- 2 - CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE AND RESERVE ESTIMATES This Annual Report on Form 20-F has been prepared in accordance with the requirements of the securities law in effect in Canada, which differ from the requirements of the United States securities laws. The terms mineral reserve, proven mineral reserve and probable mineral reserve are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101  Standards of Disclosure for Mineral Projects(NI 43-101) and the Canadian Institute of Mining, Metallurgy and Petroleum (the CIM)  CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. These definitions differ from the definitions in the United States Securities and Exchange Commission (SEC) Industry Guide 7 under the United States Securities Act of 1933, as amended (the Securities Act). Under SEC Industry Guide 7 standards, a final or bankable feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition , the terms mineral resource, measured resource, indicated resource and inferred resource are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part of or all of mineral deposits in these categories will ever be converted into reserves. Inferred mineral resources have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of contained ounces in a resource is permitted disclosure under Canadian regulations; however the SEC normally only permits issuers to report mineralization that does not constitute reserves by SEC Industry Guide 7 standards as in place tonnage and grade without reference to unit measures. Accordingly, information contained in this Annual Report on Form 20-F and the documents incorporated by reference herein contain descriptions of our mineral deposits that may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. NI 43-101 Definitions Mineral resource
     Refers to a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earths crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge.
The terms mineral resource, measured mineral resource, indicated mineral resource and inferred mineral resource used in this annual Form 20-F are Canadian mining terms as defined in accordance with NI 43-101 under the guidelines set out in the CIM Standards.Measured resource
     Refers to that part of a mineral resource for which quantity grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.Indicated resource
     Refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.


---

- 3 - NI 43-101 Definitions Inferred resource
     Refers to that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.Mineral reserve
     Refers to the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. The study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that might occur when the material is mined.
Mineral reserves are categorized as follows on the basis of the degree of confidence in the estimate of the quantity and grade of the deposit.Proven reserve
     Means, in accordance with CIM Standards, for the part of a deposit which is being mined, or which is being developed and for which there is a detailed mining plan, the estimated quantity and grade or quality of that part of a measured mineral resource for which the size, configuration and grade or quality and distribution of values are so well established, and for which economic viability has been demonstrated by adequate information on engineering, operating, economic and other relevant factors, so that there is the highest degree of confidence in the estimate. This definition differs from the standards in the United States, where proven or measured reserves are defined as reserves which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; (b) grade and/or quality are computed from the results of detailed sampling and (c) the sites for inspection, sampling and measurement are spaced so closely and the geographic character is so well defined that size, shape, depth and mineral content of reserves are well established.Probable reserve
     Means, in accordance with CIM Standards, the estimated quantity and grade or quality of that part of an indicated mineral resource for which economic viability has been demonstrated by adequate information on engineering, operating, economic and other relevant factors, at a confidence level which would serve as a basis for decisions on major expenditures. This definition differs from the standards in the United States, where probable mineral reserves are defined as reserves for which quantity and grade and/or quality are computed from information similar to that of proven reserves (under United States standards), but the sites for inspection, sampling, and measurement are further apart or are otherwise less adequately spaced, and the degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation.

  CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This Annual Report on Form 20-F and exhibits attached hereto contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and Canadian securities laws. Such forward-looking statements concern the Companys plans for its properties, operations and other matters. These statements relate to analyses and other information that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management. Statements concerning estimates of mineral resources and reserves may also be deemed to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered if the property is developed, and in the case of mineral reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as expects or does not expect, is expected, anticipates or does not anticipate, plans, estimates or intends, or stating that certain actions, events or results may, could, would, might or will be taken, occur or be achieved) are not statements of historical fact and may be forward-looking statements. Forward-looking statements are subject to a variety of risks and uncertainties, which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation: risks related to the outcome of legal proceedingsrisks related to failure to obtain adequate financing on a timely basis and on acceptable terms;political and regulatory risks associated with mining and exploration;risks related to the maintenance of exchange listings;risks related to environmental regulation and liability;the potential for delays in exploration or development activities or the completion of feasibility studies;

- 5 - the uncertainty of profitability based upon the Companys history of losses;risks and uncertainties relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits;risks related to the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses;results of prefeasibility and feasibility studies, and the possibility that future exploration, development or mining results will not be consistent with the Companys expectations;risks related to gold price and other commodity price fluctuations This list is not exhaustive of the factors that may affect our forward-looking statements. Some of the important risks and uncertainties that could affect forward-looking statements are described in this Annual Report on Form 20-F under Description of the Business Risk Factors. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Forward-looking statements are made based on managements beliefs, estimates and opinions on the date the statements are made. Investors are cautioned against attributing undue certainty to forward-looking statements.

     Risk Factors
  An investment in the common shares of the Company involves a high degree of risk and must be considered highly speculative due to the nature of the Companys business and the present stage of exploration and development of its mineral resource properties. Failure to successfully address the risks and uncertainties described below could have a material adverse effect on the Companys business, financial condition and/or results of operations, and the trading price of the Companys shares may decline and investors may lose all or part of their investment. The principal activity of the Company is mineral exploration, which is inherently risky. Exploration is also capital intensive, and with its sale of the assets related to its 49% interest in the Denton-Rawhide joint venture during fiscal 2009, the Company has no source of income. The risk factors that could affect the Companys future results include, but are not limited to, those items discussed below. In particular, the following risk factors apply: History of Losses The Company has a history of losses and may continue to incur losses for the foreseeable future. As of April 30, 2010, the Company had an accumulated deficit of $86.1 million. With the fiscal 2009 sale of its Denton-Rawhide asset, the Company has no source of revenue and there can be no assurance that the Company will realize revenue growth or achieve profitability in the future. Financing Risks The Companys sources of financing include current cash and cash equivalents balances. The Company utilizes these funding sources to finance its exploration activities and general and administrative expenses. Additional financing will likely be required in the coming fiscal year in order to meet the Companys general and administrative costs, including regulatory responsibilities and the costs associated with the Central America-Dominican Republic-United States of America Free Trade Agreement (CAFTA) action (see Item 4. Information on the Company), as well as to fund any new exploration programs that may arise if the Company acquires a new exploration project during the coming fiscal year as is the goal of its project generation efforts . Furthermore, the Company does not have the funds in place to conduct mine development activities at the El Dorado property should the Company receive the permits allowing it to undertake these activities. There can be no assurance that the Company's exploration programs will result in locating additional commercially exploitable mineral ores or that the Companys properties will be successfully developed. There can also be no assurance that the underlying assumed levels of expenses will prove to be accurate. There is no assurance that financing will be available to the Company, on reasonable and acceptable terms, during the coming fiscal year or at any time in the future. Although the Company has been successful in the past in obtaining financing through the sale of its securities, there can be no assurance that it will be able to obtain adequate financing in the future or that the terms of such financing will be favourable. Failure to obtain such additional financing could result in the Companys failure to remain a going concern, the Companys inability to continue to fund PacRims CAFTA action, or cause the delay or indefinite postponement of further exploration and development of its projects with a possible loss of some properties. Going Concern During the year ended April 30, 2010, the Company incurred a loss of $5,005 (2009  $9,443) before discontinued operations and as at April 30, 2010 has an accumulated deficit of $86,100 (2009 - $81,131). The Company will require additional funding to maintain its ongoing exploration programs and property commitments as well as for administrative purposes and CAFTA arbitration and negotiation.These conditions and risks cast substantial doubt on the validity of the going concern assumption. The Companys ability to continue operations and exploration activities as a going concern is dependent upon its ability to obtain additional funding. The Company will need to raise sufficient funds to fund ongoing exploration and administration expenses as well as its costs under its CAFTA arbitration. While the Company has been successful in obtaining its required funding in the past, there is no assurance that sufficient funds will be available to the Company in the future. The Company has no assurance that such financing will be available or be available on favorable terms. Factors that could affect the availability of financing include the progress and results of the El Dorado project and its permitting application, the resolution of international arbitration proceedings over the non-issuance of permits in El Salvador, the state of international debt and equity markets, investor perceptions and expectations and the global financial and metals markets. The Company will have to obtain additional financing through, but not limited to, the issuance of additional equity.

- 9 - The consolidated financial statements do not reflect adjustments in the carrying values of the assets and liabilities, the reported revenues and expenses, and the balance sheet classifications used, that would be necessary if the company were unable to realize its assets and settle its liabilities Maintenance of Exchange Listings The Company received notification from the NYSE Amex, LLC (NYSE Amex) in November 2009 that as of July 31, 2009 it is not in compliance with listing maintenance standards outlined in the NYSE Amex Company Guide, having at July 31, 2009 stockholders equity of less than $6,000,000 while sustaining losses from continuing operations and net losses in its five most recent fiscal years. The Company intends to take the necessary steps to rectify this non-compliance and has submitted a compliance plan to NYSE Amex detailing its plans to regain compliance by the given deadline of May 2011. The plan was accepted by the Exchange in February 2010. However, if the Company is not in compliance with the continued listing standards at the end of the plan period or the Company does not make progress consistent with the plan during the period, then NYSE Amex may initiate delisting proceedings. If the Companys common shares are delisted from NYSE Amex, shareholders will not be able to trade its common shares on NYSE Amex and certain federal and state securities law exemptions for its common shares would no longer be available. Consequently, the trading market for the Companys securities in the United States will be limited. Notwithstanding NYSE Amexs acceptance of the Companys plan, there can be not assurance that the Company will be able to carry out its plan to the satisfaction of NYSE Amex or will be able to meet the conditions require to maintain its NYSE Amex listing. Exploration, Development and Operating Risks Resource exploration, development, and operation is a highly speculative business that involves significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate. While the discovery of precious metals and other minerals may result in substantial rewards, few properties that are explored are ultimately developed into producing mines. Major expenses may be required to locate and establish economically viable mineral deposits, to develop metallurgical processes and to construct mining and processing facilities at a particular site. It is impossible to ensure that the exploration or development programs planned by the Company will result in a profitable commercial mining operation. The potential for any project to eventually become an economically viable operation depends on numerous factors including: the quantity and quality of the minerals discovered if any, the proximity to infrastructure, metal and mineral prices (which vary considerably over time) and government regulations. The exact effect these factors can have on any given exploration property can not accurately be predicted but the effect can be materially adverse. Except for the El Dorado Project, on which a pre-feasibility study was completed in 2005, none of the Company's properties have a known body of ore and the Companys proposed exploration programs are an exploratory search for ore. Although mineral resource estimates included in this document (and/or in previous regulatory documents filed by the Company) have been carefully calculated, prepared, reviewed and/or verified by independent mining experts who are Qualified Persons, and have been reviewed by the Company, these amounts are estimates only and no assurance can be given that any particular level of recovery of gold and/or silver from mineral resources or previously disclosed reserves will in fact be realized or that an identified mineral resource will ever qualify as a commercially mineable (or viable) ore body which can be legally and economically exploited. Estimates of mineral resources and reserves, production and capital costs can also be affected by such factors as environmental permitting regulations and requirements, weather, environmental factors, unforeseen technical difficulties, unusual or unexpected geological formations and work interruptions. In addition, the grade of ore ultimately mined may differ from that indicated by drilling results. There can be no assurance that the percentage of gold recovered in small scale laboratory tests will be duplicated in large scale tests under on-site conditions or in production scale ore recovery. The El Dorado Project is the Companys principal exploration property, which along with its secondary grassroots exploration projects Santa Rita and Zamora-Cerro Colorado, is located in El Salvador. As with most jurisdictions, El Salvador imposes certain requirements and obligations on the owners of exploratory properties including application requirements, periodic reporting requirements, limited terms and certain fees and royalty payments. The Company may acquire interests in properties in other North, Central and South American countries that may place substantial restrictions on the Companys exploratory and development activities. There can be no assurance that additional significant restrictions will not be placed on the Company's existing or future properties or its operations. Such restrictions may have a material adverse effect on the Companys business and results of operation. Mining operations generally involve a high degree of risk. The Companys operations are subject to all of the physical hazards and risks normally encountered in the exploration, development and production of precious metals and other minerals including unusual or unexpected geological formations, seismic activity, rock bursts, cave-ins, flooding and other conditions involved in the drilling and removal of material, any of which could result in damage to or destruction of documents, samples or drill core, damage to life or property, environmental damage and possible legal liability. It may not be possible to insure against these risks, or for economic reasons the Company may elect not to insure against these risks. The payment of liabilities as a result of the occurrence of any of these hazards may have a material adverse effect on the Companys financial position.

- 10 - There can be no assurance that the Companys exploration and acquisition programs will yield new reserves to expand current resources. The development of the Companys properties will require the commitment of substantial financial resources to conduct the time-consuming exploration and development of properties. There can be no assurance that the Company will generate any additional revenues or achieve profitability. Reliability of Mineralization Estimates Although the Company has assessed the mineral resource estimates presented herein and mineral resource and reserve estimates documented in other regulatory filings, and believes that the methods used to estimate such mineral reserves and mineral resources are appropriate, such figures are estimates. As well, estimates of mineral reserves and mineral resources are inherently imprecise and depend to some extent on statistical inferences drawn from limited drilling, which may prove unreliable. Furthermore, no assurances can be given that the indicated level of recovery of gold or other minerals will be realized. Market price fluctuations of gold or other minerals may render reserves and deposits containing relatively lower grades of mineralization uneconomic. Moreover, short-term operating factors relating to the mineral reserves, such as the need for orderly development of the deposits or the processing of new or different grades, may cause mining operations to be unprofitable in any particular period. Definitional standards for reporting mineralized material differ between United States reporting standards and the Canadian standards use in this annual report We use the terms measured resources, indicated resources and inferred resources in this annual report on Form 20-F to comply with reporting standards in Canada. We advise U.S. investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. While we have converted a portion of these reserves to proven and probable under Industry Guide 7 reserves, U.S. investors are cautioned not to assume that any part or all of the additional mineral deposits in these categories will ever be converted into mineral reserves. These terms have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of measured mineral resources, indicated mineral resources, or inferred mineral resource will ever be upgraded to a higher category. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of a feasibility study or other economic evaluations. Investors are cautioned not to assume that any part of the reported measured mineral resource, indicated mineral resource, or inferred mineral resource in this Annual Report is economically or legally mineable. See Cautionary Note to U.S. Investors Regarding Resource and Reserve Estimates above. Title to Properties PRES has applied for an exploitation concession over a portion of its El Dorado Project exploration licence area and has carried out the studies required by the authorities for this concession, including an environmental impact study (EIS). The approval of the El Dorado EIS by the Salvadoran Ministry of Environmental Natural Resources (MARN) is a requirement for approval of the exploitation concession by the Ministry of Economy. The Company cannot say with certainty if or when the authorities in El Salvador will approve the El Dorado EIS or grant PRES an exploitation concession. The exploitation concession application area covers ground protected by an exploration licence granted to PRES that nominally expired in January 2005. Legal opinions secured by the Company indicate that El Salvadoran administrative laws and procedures assure PRES exclusive rights to the proposed exploitation concession area while the application is in process, despite the underlying exploration licence having expired. There can be no assurance however that this opinion will not be challenged by regulatory authorities or other third parties and that PRESs legal rights to explore within the exploitation concession application area will be upheld indefinitely pending the outcome of the application process. The Companys exploration properties may be subject to prior unregistered agreements or transfers or local land claims and title may be affected by undetected defects. The Company has investigated and believes it has good title to its properties. However, there is no guarantee that adverse claims to title will not arise in the future, nor can the Company express an opinion on how difficult the resolution of such claims would be under the laws of foreign jurisdictions. Government Law, Environmental and Other Regulatory Requirements The Companys El Dorado, Santa Rita and Zamora-Cerro Colorado and other exploration projects are located in El Salvador and the Company holds or may acquire exploration properties in other North, Central and South American countries. Mineral exploration and mining activities in foreign countries are subject to risks normally associated with the conduct of business in foreign countries and in addition its business activities may be affected in varying degrees by political stability and government regulations as these evolve in sovereign nations. These risks may include foreign labour disputes, invalidation of governmental orders, uncertain political and economic environments, war or civil disturbances, changes in laws, changes in foreign exchange rates, regulations and policies of governments, changes in foreign tax laws, delays in obtaining necessary permits, limitations on the repatriation of earnings and original investments and increased costs of and difficulty in obtaining financing.

- 11 - Currency fluctuations, exchange controls, change to tax regimes and political action could impair the value of the Companys assets in the foreign jurisdictions in which the Company operates. Mining operations have inherent risks and liabilities associated with possible pollution of the environment and with the disposal of waste products occurring as a result of mineral exploration or the production of metals from producing mines. Laws and regulations involving the protection and remediation of the environment and governmental policies and regulations for the implementation of such laws and regulations are constantly changing and are, in general, becoming more restrictive and more costly to abide by. There may be costs and delays associated with compliance with these laws or regulations that could prohibit the Company from the development or expansion of a mine. Mine closure and reclamation cost requirements could change from current estimates. PRES has experienced significant delays in the processing of its El Dorado EIS and exploitation concession application, and as a result initiated an action against the Government of El Salvador under the Central America-Dominican Republic-United States of America Free Trade Agreement (CAFTA) international trade treaty. There can be no assurance that PRES will be successful in either obtaining its sought-after El Dorado exploitation concession, or that any legal challenges PacRim has undertaken or that the Company or its subsidiaries may choose to undertake in the future to resolve this issue will be successful. Foreign Operations The Company and its subsidiaries operate in many parts of the world that have experienced social unrest, political and economic instability and resulting governmental corruption and may operate its business in manners that are contrary to the regulations imposed in the United States and Canada. While the Company has policies in place to ensure adequate monitoring of its activities and compliance with Canadian, United States and local laws and regulations in the countries in which it operates, there can be no assurance that the Companys internal control policies and procedures always will protect it from reckless or negligent acts committed by its employees or agents. Such employees or agents may undertake actions that would result in a violation of law, including but not limited to, tax laws, customs laws, environmental laws, labor laws, permitting laws and regulations, industry laws or international anti-corruption and anti-bribery laws, including Canadian anti-corruption laws and the U.S. Foreign Corrupt Practices Act. Violations of these laws, or allegations of such violations, could disrupt the Companys business and result in a material adverse effect on its business and operations. Dependence on Management The success of the operations and activities of the Company is dependent to a significant extent on the efforts and abilities of a small number of skilled and experienced executives and personnel. Due to the small size of the Company, the loss of any of these key persons or the inability of the Company to attract and retain additional highly-skilled employees may adversely affect its business and future operations. The Company does not maintain key employee insurance on any of its employees. Conflicts of Interest The Companys directors and officers may serve as directors or officers of other resource companies or have significant shareholdings in other resource companies and, to the extent that such other companies may participate in ventures in which the Company may participate, the directors of the Company may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In the event that such a conflict of interest arises at a meeting of the Companys directors, a director who has such a conflict will declare their potential conflict and abstain from voting for or against the approval of such participation or such terms. From time to time several companies may participate in the acquisition, exploration and development of natural resource properties thereby allowing for their participation in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in respect of any one program. It may also occur that a particular company will assign all or a portion of its interest in a particular program to another of these companies due to the financial position of the company making the assignment. In accordance with the laws of British Columbia, the directors of the Company are required to act honestly, in good faith and in the best interests of the Company. In determining whether or not the Company will participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider the degree of risk to which the Company may be exposed and its financial position at that time. Competition for Other Assets Significant and increasing competition exists for the limited number of gold acquisition opportunities available worldwide. As a result of this competition, some of which is with large established mining companies having substantial capabilities and substantially greater financial and technical resources than the Company, the Company may be unable to acquire future potential gold mining properties on terms it considers acceptable. The Company also competes with other mining companies in the recruitment and retention of qualified employees.

- 12 - Increased costs could affect our financial condition. We anticipate that costs at our projects that we may explore or develop, will frequently be subject to variation from one year to the next due to a number of factors, such as changing ore grade, metallurgy and revisions to mine plans, if any, in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities such as fuel, rubber and electricity. Such commodities are at times subject to volatile price movements, including increases that could make production at certain operations less profitable. A material increase in costs at any significant location could have a significant effect on our profitability. Currency Fluctuations May Affect the Costs of Doing Business The Companys offices and primary activities are currently located in Canada, the United States, and El Salvador. Gold and silver are sold in international markets at prices denominated in U.S. dollars. However, some of the costs associated with the Company's activities in Canada may be denominated in currencies other than the U.S. dollar. Any appreciation of these currencies vis-a-vis the U.S. dollar could increase the Company's cost of doing business in these countries. In addition, the U.S. dollar is subject to fluctuation in value vis-a-vis the Canadian dollar. The Company does not utilize hedging programs to mitigate the effect of currency movements. Adequacy of Insurance Coverage The Company has purchased liability insurance that it believes is appropriate for the level of risk incurred, however there are no guarantees that the level of coverage of existing policies can or will be maintained. Furthermore, the Company does not carry insurance for political risk, nor environmental damage or pollution because such coverage cannot be purchased at reasonable costs. This lack of insurance coverage could result in material economic harm to the Company if a significant claim against the Company should occur. Reclamation Risks at Denton-Rawhide During fiscal 2009 the Company sold the assets it held through its 49% interest in the Denton-Rawhide joint venture to its 51% partner Kennecott Rawhide Mining Company (see Item 4). As part of the sale of its interest in Denton-Rawhide, the Company has provided a guarantee on 49% of any reclamation and closure costs in the event that these expenditures were to exceed $7.0 million subsequent to the date of the sale. The Coordinating Committee of the Denton-Rawhide mine estimates total reclamation and severance costs for the Denton-Rawhide mine of $9.8 million. $4.5 million in reclamation and severance costs have already been incurred, leaving an estimated $5.3 million to be expended in the future. This estimate may not be a true reflection of actual reclamation and closure costs of the Denton-Rawhide mine and the Company may recognize a potential future reclamation liability, as per the terms of its sale as described above, should actual reclamation and closure costs exceed $7.0 million in excess of reclamation and severance costs incurred prior to the date of the sale (October 30, 2008). Costs and Compliance Risks as a Result of Being a Public Company Legal, accounting and other expenses associated with public company reporting requirements have increased significantly in the past few years. The Company anticipates that general and administrative costs associated with regulatory compliance will continue to increase with recently adopted corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as well as new rules implemented by the SEC, Canadian Securities Administrators, the NYSE Amex and the TSX. The Company expects these rules and regulations to continue to result in significant legal and financial compliance costs and to make some activities more time-consuming and costly. There can be no assurance that the Company will continue to effectively meet all of the requirements of the regulations to which it must comply, including Sarbanes-Oxley Section 404and National Instrument 52-109 of the Canadian Securities Administrators. Any failure to effectively implement new or improved internal controls, or to resolve difficulties encountered in their implementation, could harm the Companys operating results, cause the Company to fail to meet reporting obligations or result in management being required to give a qualified assessment of the Companys internal controls over financial reporting or the Companys independent auditors providing an adverse opinion regarding managements assessment. Any such result could cause investors to lose confidence in the Companys reported financial information, which could have a material adverse effect on the Companys stock price. The Company also expects these rules and regulations may make it more difficult and more expensive for it to obtain director and officer liability insurance, and it may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for the Company to attract and retain qualified individuals to serve on its board of directors or as executive officers. If the Company fails to maintain the adequacy of its internal controls, the Company's ability to provide accurate financial statements and comply with the requirements of the Sarbanes-Oxley Act of 2002and/or National Instrument 52-109 of the Canadian Securities Administrators could be impaired, which could cause the Company's stock price to decrease.

- 13 - Environmental Risks and Hazards The Companys exploration, development and operational activities are subject to environmental regulation in the various jurisdictions in which it operates. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste. Environmental legislation is evolving in a manner that will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors and employees. There is no assurance that future changes in environmental regulation, if any, will not adversely affect the Companys operations. Environmental hazards may also exist on the Companys properties that are currently unknown to the Company and that have been caused by previous or existing owners or operators of the properties. Environmental approvals and permits are currently, and may in the future, be required in connection with the operations of the Company. To the extent that such approvals are required and not obtained, the Company may be curtailed or prohibited from continuing in its exploration, development or mining activities or from proceeding with its exploration or development plans for current properties. Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions that cause exploration, development or mining activities to cease or be curtailed and may include corrective measures requiring capital expenditures or remedial actions. In such an event, the Company could be required to compensate those suffering loss or damage by reason of the Companys activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations. Amendments to existing environmental laws and regulations governing exploration, development and mining activities of mining companies, or more stringent application of current laws and regulations could have a material adverse impact on the Company causing increases in exploration expenses, capital expenditures or production costs, or a reduction in production levels at producing operations, or require abandonment or delays in development of new mining properties. Future Sales of Common Shares by Existing Shareholders The sale of a large number of common shares of the Company in the public markets, or the potential for such sales, could decrease the trading price of the Companys common shares and could negatively impact the Companys ability to raise capital through future sales of common shares. We anticipate that we will raise additional capital through equity financing, which may cause substantial dilution to our existing shareholders. We may require additional equity financing be raised in the future. We may issue securities on less than favorable terms to raise sufficient capital to fund our business plan. Any transaction involving the issuance of equity securities or securities convertible into common shares would result in dilution, possibly substantial, to present and prospective holders of common shares. Foreign Private Issuer Status The Company is currently designated a foreign private issuer as defined in Rule 3b-4 under the U.S. Securities and Exchange Act of 1934, as amended, for the purposes of U.S. securities law. Although more than 50% of its voting securities are held by U.S. residents, the Company still qualifies for foreign private issuer status by meeting the following conditions as of the last business day of its most recently completed second fiscal quarter: (i) a majority of its executive officers or directors are non-U.S. citizens or residents, (ii) more than 50% of its assets are located outside the U.S., and (iii) the business of the Company is principally administered outside the U.S. The Company may in the future lose its foreign private issuer status if it fails to meet any of the aforementioned criteria. The regulatory and compliance costs to the Company under U.S. securities laws as a U.S. domestic issuer may be significantly more than the costs the Company incurs as a Canadian foreign private issuer. If the Company is not a foreign private issuer it would be required to file periodic and current reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. In addition, the Company may lose the ability to rely upon exemptions from the NYSE Amex corporate governance requirements that are available to foreign private issuers. This could have a materially adverse impact on the Companys corporate overhead costs and its ability to raise future financing. You may be unable to enforce U.S. judgments against us or our officers and directors We are incorporated under the laws of the Province of British Columbia, Canada. The majority of our directors are resident in Canada. Consequently, it may be difficult for United States investors to affect service of process within the United States upon us or upon those directors or officers who are not residents of the United States, or to realize in the United States upon judgments. Judgments of United States courts predicated upon civil liabilities may be enforceable in Canada by a Canadian court if the U.S. court in which the judgment was obtained had jurisdiction, as determined by the Canadian court, in the matter. There is substantial doubt whether an original action could be brought successfully in Canada against any of such persons or the Company predicted solely upon such civil liabilities.

- 14 - Recent market events and conditions In 2007, 2008, 2009 and into 2010, the U.S. credit markets experienced serious disruption due to a deterioration in residential property values, defaults and delinquencies in the residential mortgage market (particularly, sub-prime and non-prime mortgages) and a decline in the credit quality of mortgage backed securities. These problems led to a slow-down in residential housing market transactions, declining housing prices, delinquencies in non-mortgage consumer credit and a general decline in consumer confidence. These conditions continued and worsened in 2008, causing a loss of confidence in the broader U.S. and global credit and financial markets and resulting in the collapse of, and government intervention in, major banks, financial institutions and insurers and creating a climate of greater volatility, less liquidity, widening of credit spreads, a lack of price transparency, increased credit losses and tighter credit conditions. Notwithstanding various actions by the U.S. and foreign governments, concerns about the general condition of the capital markets, financial instruments, banks, investment banks, insurers and other financial institutions caused the broader credit markets to further deteriorate and stock markets to decline substantially. In addition, general economic indicators have deteriorated, including declining consumer sentiment, increased unemployment and declining economic growth and uncertainty about corporate earnings. These unprecedented disruptions in the current credit and financial markets have had a significant material adverse impact on a number of financial institutions and have limited access to capital and credit for many companies. These disruptions could, among other things, make it more difficult for us to obtain, or increase its cost of obtaining, capital and financing for its operations. The Companys access to additional capital may not be available on terms acceptable to it or at all. General economic conditions The recent unprecedented events in global financial markets have had a profound impact on the global economy. Many industries, including the gold and base metal mining industry, are impacted by these market conditions. Some of the key impacts of the current financial market turmoil include contraction in credit markets resulting in a widening of credit risk, devaluations and high volatility in global equity, commodity, foreign exchange and precious metal markets, and a lack of market liquidity. A continued or worsened slowdown in the financial markets or other economic conditions, including but not limited to, consumer spending, employment rates, business conditions, inflation, fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates, and tax rates may adversely affect our growth and profitability. Specifically: The global credit/liquidity crisis could impact the cost and availability of financing and our overall liquidity;the volatility of the gold price may impact our future revenues, profits and cash flow;volatile energy prices, commodity and consumables prices and currency exchange rates impact potential production costs; andthe devaluation and volatility of global stock markets impacts the valuation of our equity securities, which may impact our ability to raise funds through the issuance of equity. These factors could have a material adverse effect on our financial condition and results of operations. ITEM 4.  INFORMATION ON THE COMPANY A.
     History and Development of the Company
  The legal and commercial name of the Company is Pacific Rim Mining Corp.. The Company was formed by the amalgamation of Dayton Mining Corporation (Dayton) and Pacific Rim Mining Corp. (Pacific Rim) on April 11, 2002 under the former Company Act(British Columbia). Effective March 29, 2004, the British Columbia legislature enacted the Business Corporations Act(British Columbia) (the New Act) and repealed the former Company Act(British Columbia) which previously governed the Company. The New Act removed many of the restrictions contained in the former act, including restrictions on the residency of directors, the place of annual general meetings and limits on authorized share capital. The New Act also uses new forms and terminology. Under the New Act, every company incorporated, amalgamated or continued under the former act must complete a mandatory transition rollover under the New Act to substitute a Notice of Articles for its Memorandum within two years of March 29, 2004, after which existing articles may be altered to take advantage of new provisions contained in the New Act. Under the New Act, the directors of the Company were permitted to approve and complete this mandatory transition rollover and, accordingly, the Company filed a transition application with the British Columbia Registrar of Companies effective July 26, 2004. At the annual general meeting held on September 22, 2004, the Companys shareholders approved the removal of pre-existing company provisions that applied to the Company relating to restrictions in the former act and no longer required under the New Act. In addition, the shareholders approved new articles to bring the Companys charter documents into line with the New Act and, as permitted by the New Act, altered the authorized capital of the Company from 1,000,000,000 common shares without par value to an unlimited number of common shares without par value and the alteration of the Notice of Articles. The changes were effected and the British Columbia Registrar of Companies issued a new Notice of Articles on January 20, 2005.

- 15 - The Company is domiciled in British Columbia, Canada and is a company organized under the New Act. The Companys principal place of business is located at Suite 1050, 625 Howe Street, Vancouver, British Columbia, V6C 2T6 and its registered and records office is located on the 10thFloor, 595 Howe Street, Vancouver, British Columbia, V6C 2T5. The Company through its subsidiaries has administration offices in Nevada and El Salvador. The Companys U.S. agent is Dorsey & Whitney LLP, located at Republic Plaza Building, Suite 4700, 370 Seventeenth Street, Denver, Colorado 80202-5647, USA. Additional sources of information regarding Pacific Rim Mining Corp. include: information available on SEDAR (www.sedar.com) including the Companys unaudited interim financial statements published quarterly; the Companys 20-F filing (available at www.sec.gov); and, the Companys corporate website www.pacrim-mining.com and Spanish-language informational website (www.pacificrim.com.sv). Through its merger with Dayton Mining in 2002 and until late October 2008, Pacific Rim was 49% owner in the Denton-Rawhide residual leach gold operation, located near Fallon, Nevada. On October 29, 2008 the Company announced that it had accepted an offer from its Denton-Rawhide joint venture partner Kennecott Rawhide Mining Company (Kennecott) to purchase the net assets the Company held through its 49% interest in the joint venture. Total compensation for these net assets included US $3.1 million plus 49% of all gold and silver production from the Denton-Rawhide operation through to December 31, 2008 net of cash production costs. The Company was entitled to and received 49% of the gold and silver production from Denton-Rawhide (up to and including all gold and silver produced to December 31, 2008 only) as per the terms of sale described above. No further gold or silver production from Denton-Rawhide will be forthcoming to the Company. Pacific Rims share of gold and silver produced from the Denton-Rawhide operation during fiscal 2009 (between May and December 31, 2008) was 6,350 ounces of gold and 55,666 ounces of silver. B.
     Business overview
  Pacific Rim is an environmentally and socially responsible exploration company focused exclusively on high grade, environmentally clean gold deposits in the Americas. Pacific Rims primary asset is the high grade, vein-hosted El Dorado gold project in El Salvador. The Company also owns several similar grassroots gold projects in El Salvador and is actively seeking additional assets elsewhere in the Americas that fit its focus. Pacific Rims shares trade under the symbol PMU on both the Toronto Stock Exchange (TSX) and the NYSE Amex. Significant Events During Fiscal 2010 Significant technical and corporate events that occurred during the twelve months ended April 30, 2010 include: On November 12, 2009, the Company announced it received notice from the NYSE Amex that, based on its review of the Companys fiscal 2010 first quarter results, the NYSE Amex Company is not in compliance with Section 1003(a) (iii) of the Company Guide, having at July 31, 2009 stockholders equity of less than $6,000,000 while sustaining losses from continuing operations and net losses in its five most recent fiscal years. The Company submitted a Compliance Plan (the Plan) on December 11, 2009 which was accepted by NYSE Amex.On November 20, 2009, the Company announced that the three nominations for arbitrators in PacRims action under CAFTA and the El Salvadoran Investment Law have all accepted their appointments and as a result, the Arbitral Tribunal is therefore deemed under ICSID Arbitration Rule 6 to have been constituted.On January 4, 2010, the Government of El Salvador (GOES) filed preliminary objections to PacRims claims (the Preliminary Objection) under CAFTA and El Salvador's Investment Law. Under CAFTA Article 10.20, the Arbitral Tribunal overseeing PacRims claim is to rule on the Preliminary Objections on an expedited schedule, and to this end, conducted a hearing on the Preliminary Objection on May 31 and June 1, 2010. A ruling is expected to be issued by September 2010. PacRim believes that the GOESs objections are frivolous, without merit, and an attempt to stall the CAFTA arbitration proceedings.

- 16 - On January 14, 2010, the Company closed a private placement financing that is had announced in December 2009. Gross proceeds of CDN $2,355,000 were raised through the issuance of 11,775,000 units of the Company, each unit consisting of one common share and one common share purchase warrant.On March 4, 2010, the Company announced it had signed an amendment to the Zamora-Cerro Colorado project option agreement with the property vendors, Cerro Colorado S.A. de C.V. and Nycon Resources, Inc. This amendment provides for a deferral of the remaining Zamora-Cerro Colorado property payments (those scheduled for years 4 and 5 of the agreement), which consist of advance royalty payments to be made in cash or securities until the earlier of the date on which the Company receives confirmation that GOES has granted a mining exploitation concession for the El Dorado project or February 11, 2015. Subsequent to April 30, 2010, the following event occurred: On May 31 and June 1, 2010, a hearing on the Preliminary Objection filed by the GOES in relation to PacRims CAFTA action (see above) was held in at ICSID headquarters in Washington, DC. Under CAFTA Article 10.20, the 3-person Arbitral Tribunal hearing this case is to rule on the Preliminary Objection on an expedited schedule and is expected to issue a decision by September 2010. Current Market Status The business of mining and exploration involves a high degree of risk. The Company is entirely reliant on its current cash and cash equivalents, sale of minor gold and silver bullion balances, and future financings in order to fund legal, exploration and administration expenses. There can be no assurance that such financing will be available or be available on favourable terms, particularly considering current market conditions for issuance of capital. El Dorado Gold Project, El Salvador The Companys principal exploration property and sole material property is the El Dorado gold project, located in El Salvador approximately 65 kilometres northeast of the capital city San Salvador, and is Pacific Rims flagship advanced-stage exploration property. Pacific Rim, through PacRim and PRES, owns 100% of the El Dorado project. The El Dorado project comprises a 144 square kilometre area covered by three exploration licences with nominal expiry dates of September 28, 2013 (one licence) and September 29, 2013 (two licences) and a 12.75 square kilometre area pending conversion to an exploitation concession, which underlying exploration licence has a nominal expiry date of January 1, 2005. In accordance with Salvadoran Law, PRES presented a request for the conversion of this 12.75 square kilometre portion of the El Dorado exploration licences to an exploitation concession in December 2004. The conversion process is currently pending ministerial acceptance of PRESs EIS and issuance of environmental permits. Salvadoran administrative laws and procedures give PRES exclusive rights to the exploitation concession area while the permitting process is underway. El Dorado is subject to a royalty of 3% of net smelter returns in favour of a previous property owner. Pacific Rim has the right to buy back the royalty for $1 million for the first 1.5% and $3 million for the second 1.5%, provided that at least one half of the royalty is acquired within six months of the commencement of commercial production. In July 2008, the Company suspended all drilling activity at the El Dorado project. This decision was made in order to preserve capital and substantially reduce Pacific Rims El Salvador investment activity while the El Dorado permitting issue remains unresolved. As a result, the Company restricted its exploration activities in El Salvador and elsewhere to low-cost surface exploration work and community and environmental initiatives and has not conducted any significant exploration work to further advance the El Dorado project during fiscal 2009. In 2005 the Company completed a pre-feasibility study for the Minita deposit alone, the full details of which are provided in a NI 43-101 technical report available on SEDAR (address above). Readers are cautioned that input parameters, capital costs and commodity values have changed substantially since the 2005 pre-feasibility study was completed. A feasibility study for the El Dorado project to develop a mine plan and economic analysis of the Minita, South Minita and Balsamo deposits was initiated in fiscal 2006 and put on hiatus between late fiscal 2007 and early fiscal 2009 while the basis of the study was expanded due to the discovery of the Balsamo deposit. In February 2009 (late fiscal 2009) the Company decided to defer completion of the feasibility study. Pacific Rim intends to continue to defer completion of the feasibility study until the El Dorado permit issue is clarified and capital costs stabilize. The Company drastically reduced its exploration expenditures during fiscal 2009, which primarily affected exploration work at the El Dorado project. The Company does not intend to contemplate resuming significant exploration work designed to advance the El Dorado project further until such time as the environmental permit is received and the exploitation concession is granted. The Company intends to continue exploration activities and make expenditures required to keep the El Dorado property in good standing during fiscal 2011. CAFTA Action Initiated


---

- 17 - In April 2009, PacRim filed international arbitration proceedings against the Government of El Salvador (the Government) under CAFTA and the El Salvadoran Investment Law in its own name and on behalf of its two wholly-owned El Salvadoran enterprises, PRES and DOREX (collectively the Enterprises). A Notice of Intent to commence international arbitration proceedings had previously been filed by PacRim in December 2008. PacRim has retained the Washington, DC-based international law firm of Crowell & Moring, LLP to represent it in the arbitration and is seeking an award of damages in the hundreds of millions of dollars from the Government for its multiple breaches of international and Salvadoran law. Basis of Claim Since 2002, PRES and later DOREX have been exploring, discovering, and delineating gold deposits in El Salvador. As a result of these efforts and at the initial invitation and encouragement of the Government, PacRim and the Enterprises have developed precious metal assets and acquired rights that are significantly higher in value than the to-date investment that has already been made in El Salvador. PacRim and the Enterprises have operated in full compliance with Salvadoran law, including the countrys environmental, mining and foreign investment laws, and have met or exceeded all applicable standards while conducting business in El Salvador. Ample evidence, however, demonstrates that the Government has failed to fulfill its obligations vis-à-vis PacRim and the Enterprises. PacRims claims under CAFTA are based on the Governments breaches of international and Salvadoran law, arising out of the Governments improper failure to finalize the permitting process as it is required to do and to respect PacRims and the Enterprises legal rights to develop mining activities in El Salvador. This conduct by the Government has resulted in a significant loss to both PacRim, the Enterprises, and the local communities, and has unnecessarily delayed normal development of these valuable deposits. Pacific Rims mandate to its shareholders is to build a gold mining company that explores and develops gold deposits in an environmentally responsible manner. In meeting its responsibilities, a mine design for PRESs El Dorado gold project located in the department of Cabañas, was submitted to the Government in its final form more than two and a half years ago. Despite strong local support and the inclusion of carefully engineered and reliable environmental protections for the proposed El Dorado Mine, the Government has not met its responsibility to issue PRES the permits necessary to advance the project to the final step of full production. Arbitration Process The arbitration is administered under the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States and the Rules of Procedure for Arbitration Proceedings of the International Centre for Settlement of Investment Disputes (ICSID). ICSID is an affiliate of the World Bank and is headquartered in Washington, D.C. Developments during the twelve months ended April 30, 2010 During fiscal 2010, PacRim was informed by ICSID that three nominations for arbitrators in the action have all accepted their appointments. As a result, the Arbitral Tribunal is therefore deemed under ICSID Arbitration Rule 6 to have been constituted. On January 4, 2010, the GOES filed a Preliminary Objection to PacRims claims under CAFTA and El Salvadors Investment Law. Under CAFTA Article 10.20, the Tribunal is to rule on the Objection on an expedited schedule, set a hearing on the Objection for May 31, and June 1, 2010, and is expected to issue a ruling by September 2010. PacRim believes that El Salvador's Objection is frivolous, completely without merit, and the GOES filed it purely as an attempt to stall the arbitration proceedings. Other Properties Santa Rita Gold Project, El Salvador The Santa Rita gold project is located in central El Salvador, immediately northwest of the El Dorado project. The Santa Rita exploration licence was staked by the Companys subsidiary PRES in July 2005 after its regional reconnaissance program in El Salvador resulted in the discovery of gold-bearing quartz-calcite boulders. During fiscal 2010, the Santa Rita exploration licence expired and was immediately re-staked in accordance with local regulations by the Companys subsidiary DOREX. DOREX is currently awaiting approval of the new Santa Rita exploration licence. Despite the obvious gold potential of the Santa Rita project as indicated from early stage exploration results, the Company temporarily stepped back from exploration work at Santa Rita between fiscal 2007 and late fiscal 2008 when the project became the target of violent anti-mining protests. Exploration activities were again curtailed in July 2008 (fiscal 2009) in keeping with the Companys decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted.

- 18 - Zamora-Cerro Colorado Gold Project, El Salvador The Zamora and Cerro Colorado project comprises a 125 square kilometre land package located 50 kilometres northwest of San Salvador, in El Salvador. During fiscal 2006 Pacific Rim signed an agreement to acquire a 100% interest in the Zamora gold project in El Salvador from a consortium of private companies, which was amended in fiscal 2007 to include additional exploration licences known as Cerro Colorado. The Company has staked additional ground between the Cerro Colorado and Zamora licences it optioned in order to cover what it believes is a large gold-bearing epithermal system situated on the same regional gold belt that hosts the El Dorado and Santa Rita gold systems in El Salvador and a number of million-plus ounce gold systems in Guatemala. The Company has not yet received confirmation that the licences it staked in fiscal 2008 and early fiscal 2009 have been formally granted. On February 11, 2010, an amendment to the Zamora-Cerro Colorado option agreement was signed by the Company and the property vendors Nycon Resources, Inc. and Cerro Colorado S.A. de C.V. (together, the Optionor). Under the terms of the amended agreement, the Company will retain is 100% option on the claims comprising the Zamora-Cerro Colorado property but will defer all further and remaining option payments to the Optionor until the earlier of February 11, 2015, or such time as the Company receives an approved mining permit for the El Dorado project (being a clear signal of the GOES support of the mining industry in El Salvador). All other aspects of the option agreement remain unchanged. The schedule of advanced royalty payments required to maintain the Companys option to purchase the Zamora-Cerro Colorado property, as per the amended agreement is: Upon TSX approval of the amended agreement:
     100,000 shares plus 100,000 warrants of the Company (shares issued)Yearly advanced royalty payments:
     The greater of:First anniversary
     100,000 shares or $100,000 in shares of the Company (shares issued)Second anniversary
     140,000 shares or $140,000 in shares of the Company (shares issued)Third anniversary
     200,000 shares or $200,000 in shares of the Company (shares issued)Payment date is earlier of the date the Company receives confirmation that the GOES has granted a mining exploitation concession for the El Dorado Project and February 11, 2015
     300,000 shares or $300,000 in shares of the Company (option payment deferred  see above)Anniversary of prior payment per February 2010 amended agreement and subsequent anniversaries
     400,000 shares or $400,000 in shares of the Company (option payment deferred  see above)
  The above advanced royalty payment schedule applies to both the Zamora and Cerro Colorado exploration license options and supersedes the original agreement terms. As per the terms of the revised agreement, advanced royalty payments as outlined above will continue until production is achieved or the exploration concessions expire. Title to 100% of the Cerro Colorado and Zamora exploration licenses is to be transferred to Pacific Rim at such time as a positive production decision is made by the Company. Upon achievement of commercial production from the Cerro Colorado or Zamora claims, the Optionor is entitled to receive a 3% net smelter royalty to a maximum of $10 million (inclusive of the dollar value of the advanced royalty payments made). Despite the positive exploration results the Company has generated to date on the Zamora-Cerro Colorado project, further exploration activities were curtailed in July 2009 in keeping with the Companys decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted. The Company intends to continue exploration activities as required to keep the Zamora-Cerro Colorado licences in good standing during fiscal 2011. Generative Program Pacific Rims project generation initiatives focus on acquiring only the highest quality projects the Company believes have the best odds of discovery. The Company focuses solely on low-sulfidation epithermal gold systems, which are environmentally-clean, high grade, and low cost. After reducing its exploration focus in El Salvador in July 2008 (fiscal 2009), Pacific Rim shifted the focus of its grassroots exploration initiatives to other jurisdictions that have similarly prospective mineral potential but a more robust appreciation of the economic benefits of the mining industry. Using its unique understanding of epithermal gold systems in the Central American Gold Belt, Pacific Rim has been very successful in locating new, high grade gold-bearing systems in the past and is ideally equipped to apply this formula for discovery in neighbouring jurisdictions. In fiscal 2009 the Company filed for two large exploration concessions in the Las Juntas de Abongares and La Union mining districts in Costa Rica on which occur epithermal vein systems with significant historic gold production. However, the concessions were never approved and Costa Rica recently reinstated a moratorium on certain mining practices that could impact the future of these concessions. The Company does not intend to pursue receipt of the concessions or focus its efforts in Costa Rica in the near future.

- 19 - The Company is continuing to evaluate potential project acquisitions elsewhere in the Americas that fit its exploration criteria and during fiscal 2010 conducted substantial due diligence work on one project that it is pursuing for acquisition. However there are no guarantees that any project evaluation or due diligence work currently underway will result in a positive outcome or that the Company will be successful in acquiring any of the projects it is currently evaluating. Competition The mineral property exploration and development business, in general, is intensively competitive and there is not any assurance that even if commercial quantities of ore are discovered, a ready market will exist for sale of same. Numerous factors beyond our control may affect the marketability of any substances discovered. These factors include market fluctuations; the proximity and capacity of natural resource markets and processing equipment; and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of mineral and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may make it difficult for us to receive an adequate return on investment. We compete with many companies possessing greater financial resources and technical facilities for the acquisition of mineral concessions, claims, leases and other mineral interests as well as for the recruitment and retention of qualified employees. Seasonality There are no seasonal affects on our mineral properties. C.

- 20 - El Salvador Properties El Salvador Mining Regime The following is based on the Companys understanding of the El Salvador mining regime. Under the laws of El Salvador, the government owns all mineral rights. All private and government-owned lands that have not been declared areas of protection for reasons of national sovereignty, areas of cultural or social interest, areas of ecological or environmental protection or areas of capitation of surface or underground waters for potable water supply; zones occupied by public service facilities; or areas that are within the urban limit of cities or towns are open to exploration and are available through application for an exploration license, which can subsequently be converted to an exploitation concession upon compliance with certain conditions. An exploration license is held by payment of an annual fee, compliance with the environmental laws of the country and fulfilment of the technical exploration program, which may be modified on an annual basis. El Salvadorian mining laws do not discriminate between nationals and foreigners. El Salvadors current mining law, which was enacted in 1996 and last amended in 2001, governs the provisions for granting of exploration licences and exploitation concessions. By granting an exploitation concession, the El Salvadoran Ministry of Economys Department of Hydrocarbons and Mines confers upon the applicant the right to produce and sell valuable commodities recovered from the natural resources within the area of the concession. To be granted an exploitation concession, which is a necessary step to commencing mining extraction activities, an environmental permit based on an Environmental Impact Study (EIS) must first be approved by the Salvadoran Ministry of Environment and Natural Resources (MARN). The applicant must also satisfy a number of other conditions. Once granted, the concession requires that development activities commence within 12 months of the date of the final concession agreement and that the mine and associated facilities be built and operated in accordance with the conditions of the environmental permit. El Dorado Property, El Salvador The Companys most advanced property in El Salvador is the El Dorado Property, which consists of three exploration licenses (contiguous to and completely surrounding the pending exploitation concession area), which the Company, indirectly through its wholly-owned subsidiaries, holds as to a 100% interest. The information presented below summarizes information prepared under the supervision of Mr. Steven Ristorcelli, P.Geo., of Mine Development Associates. This information is included in a report entitled Technical Report Update on the El Dorado Project Gold and Silver Resources dated March 3, 2008 co-authored by Mr. Ristorcelli and Mr. Peter Ronning, P.Eng. each of whom are independent Qualified Persons as defined in NI 43-101. Information presented under the headings Recent Developments, January 2008 Updated Resource Estimate, Environmental Impact Study and Mining Permit CAFTA Action and Summary has been updated by the Company to reflect developments that have occurred since March 3, 2008, being the date of the most recent El Dorado Technical Report. Predecessor Dayton upon its acquisition of Mirage Resource Corp. in April 2000 acquired the El Dorado Property. Mirage initially acquired the El Dorado Property by option agreement dated June 23, 1993 from Zinc Metal Company (ZMC) of Toronto, and its wholly-owned subsidiary, New York and El Salvador Mining Company. The option was exercised on August 25, 1994 in accordance with its terms by payment of $175,000 to ZMC and by the parties having incurred aggregate expenditures in excess of $800,000. Pursuant to the terms of the option agreement, the El Dorado Property is subject to annual advance minimum royalty payments, which are the greater of $50,000 per year or a 3% net smelter return royalty in favour of ZMC. The Company has the right to purchase the royalty from ZMC for $4,000,000 ($1,000,000 for the first one-half and $3,000,000 for the second one half) provided that at least one-half of the royalty is acquired within six months of the commencement of commercial production. In addition, the government of El Salvador is entitled to a 2% net smelter return royalty. By agreement dated March 29, 2006, the Company superseded an option agreement dated November 14, 2003 to acquire a parcel of land suitable for mineral exploitation activities within the El Dorado exploration licence area. Under the terms of the new agreement, the Company has prepaid an annual rental fee in the amount of $29,000 with the option to purchase the parcel for a payment of $971,000 at any time up to April 1, 2007. During fiscal 2007 the Company commenced the process of exercising its option to purchase one of the larger parcels of land over which it holds a purchase option agreement (negotiated during fiscal 2004), and advanced to the property owner $0.3 million of the $1.0 million total negotiated option payment. During fiscal 2008, upon transfer of title in the parcel of land to the Company, the final $0.7 million was paid. Although the El Dorado Property contains geological mineral resources, none of the Companys properties in El Salvador, including the El Dorado Property, contain known ore reserves (as defined under the SECs Industry Guide 7) and all work programs are exploratory searches for ore grade mineralization. Property Description and Location


---

- 21 - The El Dorado Property (see Figures 1 and 2 below) is comprised of three exploration licenses totalling 14,407 hectares with nominal expiry dates of September 28, 2013 (one license) and September 29, 2013 (two licenses), and the 1,275 hectare area of the pending Exploitation Concession, which underlying exploration license has a nominal expiry date of January 1, 2005. The Company continues to hold the 1,275 hectare pending Exploitation Concession area beyond its expiry date as it has declared its intention to convert the land holding to an Exploitation Concession, which will have a term of 30 years and may be extended if warranted. See El Salvador Mining Regime above. The cost to hold the licenses is a rental of $300 per square kilometre, amounting to $47,046 per year. The Company is up to date with the regulatory obligations required to maintain the licenses in good standing and is awaiting final approval of the pending exploitation concession. In addition to its mineral rights, the Company owns approximately 765,000 square metres of real estate in the central part of the El Dorado Property. Part of the El Dorado license area was the scene of mining by another company between 1948 and 1953. The Company and its environmental consultants believe that there are no existing environmental liabilities on the project related to that earlier period of production nor to the exploration activities of the Company and its predecessor companies. The exploration license area contains several prospects and deposits. Their stage of exploration and development ranges from recently discovered veins that have never been drilled to deposits that have resource estimates. The Companys permanent installations on the property at the present time consist of a laboratory for crushing rock samples and core storage warehouses with facilities for describing and sampling drill core. None of the mid-20thcentury mine workings are accessible at present. The El Dorado Property is in the Department of Cabañas, approximately 74 kilometres northeast of San Salvador, the capital city of the nation, and 10 kilometres southwest of the town of Sensuntepeque.

- 24 - Accessibility, Climate, Local Resources, Infrastructure and Physiography The El Dorado Property is accessible by a paved road that crosses the El Dorado Property. The travel time from the project site to San Salvador is approximately two and one-half hours, depending on traffic levels. The area has a large rural population and Sensuntepeque is a moderate sized town of approximately 20,000 people. Unskilled labour and persons with general business and technical skills should be readily available. El Salvador does not have an indigenous mining industry, so personnel with exploration and mining skills need to be trained or come from elsewhere. The usual public utilities are available in Sensuntepeque. The communication infrastructure, including telephone and internet, is serviceable. The existing buildings on the project site are connected to the national electrical grid, but the power supply is not considered reliable enough to service a mine. The terrain in the El Dorado Property area is one of moderate relief surrounded by higher hills to the north, east, and west. Elevations range between 200 m and 800 m above sea level. A tropical climate prevails, with a pronounced wet season from May to October and a dry season the remainder of the year. The project area contains shallow topsoils and volcanic subsoils that are cultivated for seasonal crops. Five perennial streams or rivers traverse the El Dorado License area. Water levels vary with the seasons with good flows being maintained during the wet season. History The colonial Spanish discovered gold in the district in the early 1500s, and there was sporadic, largely unrecorded small-scale production until the late 1800s. In the period from 1948 to 1953, the New York and El Salvador Mining Company operated an underground mine, producing approximately 270,000 tonnes of ore yielding about 72,500 troy ounces (2,250 kilograms) of gold. Extensive exploration since 1993 has included surface geological mapping, rock sampling and prospecting, campaigns of hand and bulldozer trenching, core drilling, and minor reverse circulation drilling. Geological Setting El Salvador can be divided into four morphological-geological units: Coastal Plains, Coastal Ranges, Great Interior Valley, and the Northern Mountain Ranges. El Dorado is situated in the Great Interior Valley, underlain by Eocene felsic to mafic volcanic rocks; in other words, dark to light coloured volcanic rocks in the order of 38 to 55 million years old. Mineralization on the El Dorado Property consists of gold and silver bearing quartz veins that are contained within the volcanic rocks. The gold and silver bearing veins of the El Dorado district, of which at least 36 exceed 1 m in width, occur over an area exceeding 50 square kilometres. Vein mineralization is dominated by quartz and calcite and ranges in width between 1 m and 15 m in surface exposures. The vein systems are up to 3 km in length, dip steeply, and generally form ridges. The mineralization fits the model of the low sulphidation epithermal type of mineralization, also referred to as the adularia-sericite type. A number of deposits around the world that belong to this type are being profitably mined. In terms of its structure and mineral deposits the Exploration License Area can be divided into 3 districts, Central, Northern, and Southern. The three districts are separated from each other by northwest trending regional scale faults whose primary displacement was lateral. Within each district, deposits are contained within quartz veins that formed along fractures that opened under tension. The mineralized veins are for the most part within about 30 degrees of vertical and trend generally north-south, but there is considerable variation both within and between districts. Exploration The long history of recent exploration on the El Dorado Property includes extensive mapping of mineralized structures, lithogeochemical sampling, trenching and drilling. There have been numerous ancillary studies including environmental base line work. Geological mapping to varying levels of detail, done by the Company and its predecessors, covers approximately 2,000 hectares of the 14,400 hectare property. Digital maps have been generated at scales ranging from 1:1,000 to 1:10,000. In addition, the project archives contain numerous individual maps of trenches, veins and target areas at various scales. The geological mapping is continuing, along with lithogeochemical sampling and prospecting. The geological mapping is accompanied by frequent sampling of the rocks on the surface. The samples are variously described as channel samples, chip channel samples, selected chips, random chips and grab samples.


---

- 25 - Mineralization The El Dorado License area contains many deposits, prospects and occurrences in veins, hot spring deposits and hydrothermal breccias. They are found in three districts, north, central and south, that are distinguished from each other by the dominant vein orientations and the level of the hydrothermal system that is exposed on the present-day surface. The veins have complex, multi-stage histories of formation. The dimensions of mineralized veins are as varied as their exploration status, ranging from those known only in single outcrops to those that have been traced on the surface over lengths of between one and two kilometres. Systems of related veins are up to three kilometres long. In those veins that have been mined or extensively drilled, mineralization has been demonstrated to exist over vertical intervals of up to 300 metres. (In considering vein lengths and vertical dimensions it is important to note that at a detailed level mineralization in this type of system is highly variable). Sampling and Analysis The sampling method used by the Company field personnel varies with the purpose of the sample. Geologists doing initial reconnaissance or prospecting may collect selected grab samples from new discoveries. Such samples would be intended only to determine if minerals of interest are present, not to estimate grades for any volume of material. For more systematic sampling, outcrops are cleaned off and in some cases shallow hand trenches are dug. Continuous chip samples are collected over intervals selected by a geologist. In many cases local labourers do the sampling, under a geologists supervision. The manner of sampling is recorded in field notes and is entered into the digital database of surface samples. Intervals from drill core to be sampled are selected by the geologist logging the core. All vein material and visibly mineralized material is sampled, with enough immediately adjacent, apparently unmineralized material sampled to make sure that all intervals are adequately tested. Sampling is done after logging is complete. The core is sawn in half along its axis. The Companys immediate predecessor as operator, Dayton, also used a rock saw for sampling core from 13 holes it drilled in 2000. Operators prior to Dayton used a percussion core splitter. Core recovery, which affects the degree to which samples are representative, is very good in the current drilling. In mineralized intervals it averages better than 98%. In past drilling, prior to the Company becoming operator, resource estimators found local problems with core recovery, finding that it averaged as low as 76% in some mineralized veins. The Company collected a large quantity of unmineralized material from a site in the region. This material is used as sample blanks that are inserted into the sample stream at a rate of one into every batch of 25 samples, as a quality control measure. All of the Companys samples are analyzed at the laboratory of Inspectorate America in Sparks, Nevada. About 25% of the samples are analyzed in duplicate by selecting a batch of material already pulverized by Inspectorate and sending it to another lab, American Assay. Once the results of the re-analysis are received, about 15% to 20% of the duplicated samples are selected for re-analysis starting with the coarse reject material. All samples which return gold results exceeding 3 g Au/tonne in the initial analysis are analyzed again using a fire assay preparation with a gravimetric finish. Security of Samples All sampling is done by the Companys employees, either geologists or labourers supervised by geologists. Once collected, samples are kept at the Companys on-site facility until they are picked up by employees of Inspectorate Americas Guatemalan affiliate. They are transported by road to the Guatemalan laboratory, where they are prepared and trans-shipped to Nevada for analysis. Some of the samples may, from time to time, be opened and inspected by border officials at the border crossing from El Salvador to Guatemala. Metallurgy Metallurgical test work has shown the El Dorado mineralization responds well to milling and cyanide leaching. Recoveries of over 92% for gold and over 88% for silver are expected. Historic recoveries during past production ranged from 87% to 91.5% for gold and 77.7% for silver. January 2008 Updated Resource Estimate On January 17, 2008 the Company released the results of an updated resource estimate for the El Dorado gold project, in which 1.4 million gold equivalent ounces were tabulated in the Measured and Indicated resource categories combined and a further 0.3 million gold equivalent ounces were tabulated in the Inferred category. Full details of the 2008 El Dorado resource estimate, by deposit and resource category, are presented below.

  The mineral resource estimates presented above have been calculated in accordance with National Instrument 43-101 as required by Canadian securities regulatory authorities, which differs from standards of the SEC. The resource estimates contained in this discussion would not be permitted in reports of U.S. Companies filed with the SEC. See Cautionary Note to U.S. Investors Regarding Resource and Reserve Estimates above. The resources were estimated by interpreting drill intercepts in cross section, coding samples, capping assays, compositing to vein thicknesses, and estimating grades and thicknesses of each of the veins into three dimensional grade thickness models. Each of the three veins comprising the Minita resource, ten veins comprising the South Minita resource, and five veins comprising the Balsamo resource were estimated separately. The 4.0 g/t cut-off grade (wherein gold equivalents are based on a silver to gold ratio of 70:1 and greater than a grade-times-thickness of 4 (g AuEq/t x metres)) is predicated on estimated operating costs of $49.68 per tonne, estimated gold recovery of 90% and a gold price of $400 per ounce. These parameters stem from the Companys 2005 El Dorado prefeasibility study, the results of which are based on various input estimates related to costs and commodity prices that were current at the time of its publication. Readers are cautioned that significant changes have occurred in a number of the inputs used in the January 2005 El Dorado prefeasibility study since its publication in January 2005. However, the Company and its consultants elected to maintain the 4.0 g/t gold equivalent cut-off grade for the 2008 El Dorado resource estimate in order to facilitate comparisons between the current resource estimate and the 2006 resource estimate. Full technical reports related to the 2008 El Dorado resource estimate, the 2006 El Dorado resource estimate and the 2005 El Dorado pre-feasibility study are publicly available on SEDAR at www.sedar.com.

- 27 - The foregoing disclosure under January 2008 Updated Resource Estimate is based on information prepared under the supervision of Mr. Steven Ristorcelli, P.Geo., of Mine Development Associates, contained in a report entitled Technical Report Update on the El Dorado Project Gold and Silver Resources dated March 3, 2008 co-authored by Mr. Ristorcelli and Mr. Peter Ronning, P.Eng. each of whom are independent Qualified Persons. This information has further been reviewed and verified by Mr. William Gehlen, Certified Professional Geologist and a Qualified Person. Mr. Gehlen is the Vice-President of Exploration of the Company and supervises the Companys exploration work on the El Salvador properties. The Companys sampling procedures follow the Exploration Best Practices Guidelines outlined by the Mining Standards Task Force and adopted by the TSX. Samples have been assayed using fire assay with a gravimetric finish on a 30-gram split. Quality control measures, including check- and sample standard-assaying, are being implemented. Samples were assayed by Inspectorate America Corporation in Reno, Nevada, an ISO 9002 certified laboratory, independent of the Company. Recent Developments In July 2008, the Company suspended all drilling activity at the El Dorado project. This decision was made in order to preserve capital and substantially reduce Pacific Rims El Salvador investment activity while the El Dorado permitting issue remains unresolved. See Environmental Impact Study and Mining Permit.As a result, the Company restricted its exploration activities in El Salvador and elsewhere to low-cost surface exploration work and community and environmental initiatives and did not conduct any significant exploration work to further advance the El Dorado project during fiscal 2010. A full feasibility study for the El Dorado project was initiated in fiscal 2007 following the discovery and delineation of the South Minita deposit but before the discovery of the Balsamo deposit. In late fiscal 2007 the Company elected to defer completion of the study in order to include the resources being drilled at the newly discovered Balsamo deposit in addition to the Minita and South Minita resources. During fiscal 2009 work on the El Dorado project feasibility study, including an underground mine plan for the Minita, South Minita and Balsamo deposits, processing facility and tailings impoundment designs, and an economic analysis of the proposed combined operation, was restarted under the direction of SRK Consulting. In its 2008 Annual Report the Company anticipated the El Dorado feasibility study would be completed during the 2009 fiscal year. However, in February 2009 the Company decided to again defer completion of the feasibility study, in this case because of: unpredictability in capital costs as changes in commodity prices due to recent economic volatility become reflected in the prices for capital items; the Companys focus on saving cash until these inputs have stabilized and the study can accurately reflect changed economic realities; and, uncertainty in the timing of the El Dorado permitting process. The Company believes recent economic volatility will continue in the short term and that capital costs and commodity values will remain in a state of flux for the coming months, a position echoed by numerous industry analysts. Pacific Rim intends to complete the feasibility study when the El Dorado permit issue is clarified and capital costs stabilize. Environmental Impact Study and Mining Permit In September 2004, PRES submitted an EIS to MARN for a 750 tonne per day operation based on producing precious metals from the Minita deposit alone. In September 2005, the finalized EIS, which incorporated initial comments from MARN, was resubmitted to MARN. MARN then conveyed its technical approval of the EIS, and instructed PRES to submit the EIS for public comment, which was carried out in October 2005. In March 2006, PRES received from MARN a list of issues raised during the public comment period and was asked to amend the EIS to address these and a number of other issues. In October 2006, the amended EIS, which included the requested clarification on a number of items, was resubmitted to MARN. Finally, in December 2006, PRES submitted a proposal for a water treatment plan in response to additional comments by MARN. Over three years have passed since the El Dorado EIS was submitted in its final form to MARN, during which time MARN has failed to take action on approval of the EIS. This in turn is preventing a resolution to PRESs exploitation concession application.

- 28 - CAFTA Action In April 2009 PacRim filed international arbitration proceedings against the Government of El Salvador (the Government) under CAFTA in its own name and on behalf of PRES and DOREX (collectively the Enterprises). A Notice of Intent to commence international arbitration proceedings had previously been filed by PacRim in December 2008. PacRim has retained the Washington, DC-based international law firm of Crowell & Moring, LLP to represent it in the arbitration and is seeking award of damages in the hundreds of millions of dollars from the Government for its multiple breaches of international and Salvadoran law. Basis of Claim Since 2002, PRES and later DOREX have been exploring, discovering, and delineating gold deposits in El Salvador. As a result of these efforts and at the initial invitation and encouragement of the Government, PacRim and the Enterprises have developed precious metal assets and acquired rights that are significantly higher in value than the to-date investment that has already been made in El Salvador. PacRim and the Enterprises have operated in full compliance with Salvadoran law, including the countrys environmental, mining and foreign investment laws, and have met or exceeded all applicable standards while conducting business in El Salvador. Ample evidence, however, demonstrates that the Government has failed to fulfill its obligations vis-à-vis PacRim and the Enterprises. PacRims claims under CAFTA are based on the Governments breaches of international and Salvadoran law,arising out of the Governments improper failure to finalize the permitting process as it is required to do and to respect PacRims and the Enterprises legal rights to develop mining activities in El Salvador. This conduct by the Government has resulted in a significant loss to PacRim, the Enterprises, and the local communities, and has unnecessarily delayed normal development of these valuable deposits. Pacific Rims mandate to its shareholders is to build a gold mining company that explores and develops gold deposits in an environmentally responsible manner. In meeting its responsibilities, a mine design for PRESs El Dorado gold project located in the department of Cabañas, was submitted to the Government in its final form more than two and a half years ago. Despite strong local support and the inclusion of carefully engineered and reliable environmental protections for the proposed El Dorado Mine, the Government has not met its responsibility to issue PRES the permits necessary to advance the project to the final step of full production. Arbitration Process With its filing on April 30, 2009, PacRim formally commenced arbitration against the Government of El Salvador (GOES) under CAFTA and the El Salvadoran Investment Law. The arbitration is administered under the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States and the Rules of Procedure for Arbitration Proceedings of the International Centre for Settlement of Investment Disputes (ICSID). ICSID is an affiliate of the World Bank and is headquartered in Washington, D.C. During fiscal 2010, PacRim was informed by ICSID that three nominations for arbitrators in the action have all accepted their appointments. As a result, the Arbitral Tribunal is therefore deemed under ICSID Arbitration Rule 6 to have been constituted. On January 4, 2010, the GOES filed a Preliminary Objection to PacRims claims under CAFTA and El Salvadors Investment Law. Under CAFTA Article 10.20, the Tribunal is to rule on the Objection on an expedited schedule, set a hearing on the Objection for May 31, and June 1, 2010, and is expected to issue a ruling by September 2010. PacRim believes that El Salvador's Objection is frivolous, completely without merit, and the GOES filed it purely as an attempt to stall the arbitration proceedings. PacRim fully expects that the Tribunal will reject the Preliminary Objection and proceed with the arbitration claim. Summary The El Dorado gold project is Pacific Rims most advanced exploration (and sole material) project, has been the primary focus of its exploration efforts for the past eight years and the recipient of the bulk of its exploration expenditures. The project has current estimated resources of 1.4 million gold equivalent ounces in the Measured and Indicated categories combined plus a further 0.3 million gold equivalent ounces Inferred. Because the average grade of these resources (approximately 10.5 gold equivalent grams per tonne) is relatively high, the deposits are expected to be relatively low cost to produce from underground workings. Importantly, the El Dorado deposits are also environmentally clean and their production and processing is expected to have a negligible impact on the local environment. The El Dorado project has delivered many technical successes however, its path forward to development and operation has been hampered by excessively lengthy delays in the permitting process on the part of the GOES. The Company drastically reduced its exploration expenditures during both fiscal 2009 and 2010, which primarily affected exploration work at the El Dorado project. The Company does not intend to contemplate resuming significant exploration work at the El Dorado project until such time as the environmental permit is received and the exploitation concession is granted. The Company intends to continue exploration activities and make expenditures required to keep the El Dorado property in good standing during fiscal 2011.

- 29 - Santa Rita Gold Project, El Salvador There are no known ore reserves on the Santa Rita property and all work programs on the property are exploratory searches for ore grade mineralization. The Santa Rita gold project is located in central El Salvador, immediately northwest of the El Dorado project. The Santa Rita exploration licence was staked by the Companys subsidiary PRES in July 2005 after its regional reconnaissance program in El Salvador resulted in the discovery of gold-bearing quartz-calcite boulders. Subsequent to the end of fiscal 2009, the Santa Rita exploration licence expired and was immediately re-staked by the Companys subsidiary DOREX. DOREX is currently awaiting approval of the new Santa Rita exploration licence. PRES discovered an epithermal quartz-calcite vein system at Santa Rita in fiscal 2006. Two distinct veins were originally discovered and surface rock channel samples collected from along the length of one of these, the 2+ kilometre long Trinidad vein, which returned anomalous gold (between 6.4 g/t gold and 118.3 g/t over vein widths of 1 to 2 meters) at various localities along its length. In late fiscal 2006 PRES received a permit from MARN to conduct a drill program on the Santa Rita gold project. However, during fiscal 2007 the Company stepped back from exploration work at Santa Rita when the project became the target of anti-mining protests. Exploration work at Santa Rita resumed during fiscal 2008 and continued into fiscal 2009. During this most recent exploration campaign, PRES discovered several new veins on the Santa Rita property that significantly expanded the prospective target area, and undertook a surface trenching and sampling program that revealed the Trinidad vein to be significantly wider than previously understood. In addition to the surface exploration work described above, during fiscal 2009 PRES undertook a short drill program that tested the Trinidad vein system over a strike length of approximately 500 metres. This program was carried out in a low impact, low visibility manner. It was also conducted at that specific time primarily in order to satisfy work requirements necessary to maintain PRESs legal tenure of the Santa Rita licences. In the end 9 shallow holes were drilled on the Trinidad vein, the results of which confirmed that the Trinidad vein extends to below surface and contains anomalous gold. The Company believes that further drill testing is clearly warranted. Notwithstanding the excellent exploration potential demonstrated to date at the Santa Rita project, exploration activities were curtailed in July 2008 in keeping with the Companys decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted. DOREX is currently awaiting receipt of approval of its application for the new Santa Rita exploration licence. The foregoing disclosure has been prepared by or under the supervision of William Gehlen, Certified Professional Geologist, a Qualified Person for the purposes of NI 43-101. Mr. Gehlen is the Vice-President of Exploration of the Company. The Companys sampling procedures follow the Exploration Best Practices Guidelines outlined by the Mining Standards Task Force and adopted by the TSX. Samples have been assayed using fire assay with a gravimetric finish on a 30-gram split. Quality control measures, including check- and sample standard-assaying, are being implemented. Samples were assayed by Inspectorate America Corporation in Reno, Nevada, an ISO 9002 certified laboratory, independent of the Company. Zamora-Cerro Colorado Gold Project, El Salvador During fiscal 2006 Pacific Rim signed an agreement to acquire a 100% interest in the Zamora gold project in El Salvador from a consortium of private companies, which was amended in fiscal 2007 to include additional exploration licences known as Cerro Colorado. On February 11, 2010, an amendment to the Zamora-Cerro Colorado option agreement was signed by the Company and the property vendors Nycon Resources, Inc. and Cerro Colorado S.A. de C.V. (collectively, the Optionor). Under the terms of the amended agreement, the Company will retain is 100% option on the claims comprising the Zamora-Cerro Colorado property but will defer all further and remaining option payments to the Optionor until the earlier of February 11, 2015, or such time as the Company receives an approved mining permit for the El Dorado project (being a clear signal of the GOES support of the mining industry in El Salvador). All other aspects of the option agreement remain unchanged. The schedule of advanced royalty payments required to maintain the Companys option to purchase the Zamora-Cerro Colorado property, as per the amended agreement is:


---

- 30 - Upon TSX approval of the amended agreement:
     100,000 shares plus 100,000 warrants of the Company (shares issued)Yearly advanced royalty payments:
     The greater of:First anniversary
     100,000 shares or $100,000 in shares of the Company (shares issued)Second anniversary
     140,000 shares or $140,000 in shares of the Company (shares issued)Third anniversary
     200,000 shares or $200,000 in shares of the Company (shares issued)Payment date is earlier of the date the Company receives confirmation that the Government of the Republic of El Salvador has granted a mining exploitation concession for the El Dorado Project and February 11, 2015
     300,000 shares or $300,000 in shares of the Company (option payment deferred  see above)Anniversary of prior payment per February 2010 amended agreement and subsequent anniversaries
     400,000 shares or $400,000 in shares of the Company (option payment deferred  see above)
  The above advanced royalty payment schedule applies to both the Zamora and Cerro Colorado exploration license options and supersedes the original agreement terms. As per the terms of the revised agreement, advanced royalty payments as outlined above will continue until production is achieved or the exploration concessions expire. Title to 100% of the Cerro Colorado and Zamora exploration licenses is to be transferred to Pacific Rim at such time as a positive production decision is made by the Company. Upon achievement of commercial production from the Cerro Colorado or Zamora claims, the sellers are entitled to receive a 3% net smelter royalty to a maximum of $10 million (inclusive of the dollar value of the advanced royalty payments made). The Zamora and Cerro Colorado claims comprise a 125 square kilometre land package located 50 kilometres north of San Salvador, in El Salvador. The Company has staked additional ground between the Cerro Colorado and Zamora licences it optioned in order to cover what the Company believes is a large gold-bearing epithermal system situated on the same regional gold belt that hosts PRESs El Dorado and Santa Rita gold systems in El Salvador and a number of million-plus ounce gold systems in Guatemala. The Company has not yet received confirmation that the licences it staked in fiscal 2008 and early fiscal 2009 have been formally granted. Despite the positive exploration results the Company has generated to date on the Zamora-Cerro Colorado project, further exploration activities were curtailed in July 2009 in keeping with the Companys decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted. The Company intends to continue exploration activities required to keep the Zamora-Cerro Colorado licences in good standing during fiscal 2011. The foregoing disclosure has been prepared by or under the supervision of William Gehlen, Certified Professional Geologist, a Qualified Person for the purposes of NI 43-101. Mr. Gehlen is the Vice-President of Exploration of the Company. The Companys sampling procedures follow the Exploration Best Practices Guidelines outlined by the Mining Standards Task Force and adopted by the TSX. Samples have been assayed using fire assay with a gravimetric finish on a 30-gram split. Quality control measures, including check- and sample standard-assaying, are being implemented. Samples were assayed by Inspectorate America Corporation in Reno, Nevada, an ISO 9002 certified laboratory, independent of the Company. Generative Program Pacific Rims project generation initiatives focus on acquiring only the highest quality projects the Company believes have the best odds of discovery. The Company focuses solely on low-sulfidation epithermal gold systems, which are environmentally-clean, high grade, and low cost. After reducing its exploration focus in El Salvador in July 2008 (fiscal 2009), Pacific Rim shifted the focus of its grassroots exploration initiatives to other jurisdictions that have similarly prospective mineral potential but a more robust appreciation of the economic benefits of the mining industry. Using its unique understanding of epithermal gold systems in the Central American Gold Belt, Pacific Rim has been very successful in locating new, high grade gold-bearing systems in the past and is ideally equipped to apply this formula for discovery in neighbouring jurisdictions. In fiscal 2009 the Company filed for two large exploration concessions in the Las Juntas de Abongares and La Union mining districts in Costa Rica on which occur epithermal vein systems with significant historic gold production. However, the concessions were never approved and Costa Rica recently reinstated a moratorium on certain mining practices that could impact the future of these concessions. The Company does not intend to pursue receipt of the concessions or focus its efforts in Costa Rica in the near future. The Company is continuing to evaluate potential project acquisitions elsewhere in the Americas that fit its exploration criteria and during fiscal 2010 conducted substantial due diligence work on one project that it is pursuing for acquisition. However there are no guarantees that any project evaluation or due diligence work currently underway will result in a positive outcome or that the Company will be successful in acquiring any of the projects it is currently evaluating.

- 31 - Environmental Matters Reclamation  Denton-Rawhide During fiscal 2009 the Company sold the assets it held through its 49% interest in the Denton-Rawhide joint venture to its 51% partner Kennecott Rawhide Mining Company. As part of the sale of its interest in Denton-Rawhide, the Company has provided a guarantee on 49% of any reclamation and closure costs in the event that these expenditures were to exceed $7.0 million. The Rawhide Joint Venture has put in place ongoing pollution control and monitoring programs at Denton-Rawhide. A reclamation and closure plan for Denton-Rawhide has been submitted to the Bureau of Land Management and the Nevada Department of Environmental Protection and is currently awaiting approval. Kennecott has estimated a total of $4.9 million in reclamation and closure costs under the proposed plan. Kennecott, on behalf of the Rawhide Joint Venture, has posted surety bonds as required for compliance with state and local closure, reclamation and environmental obligations. Estimated future reclamation and property closure costs for Denton-Rawhide are based on current legal and regulatory requirements. Actual costs incurred for reclamation activities in future periods could differ from the amounts estimated. Additionally, future changes to environmental laws and regulations could affect the extent of reclamation and remediation work required to be performed by the Company. Any such changes in future costs could materially impact the amounts charged to operations for reclamation and remediation. The Bureau of Mining Regulation and Reclamation (BMRR), in cooperation with other state, federal and local agencies regulates mining activities in Nevada under regulations adopted in 1989. The Nevada Administrative Code (NAC) 445A.350-NAC 445A.447 and (NAC) 519A.010 - NAC 519A.415 were developed to implement the requirements of the Nevada Revised Statutes (NRS) 445A.300-NRS 445A.730 and (NRS) 519A.010 - NRS 519A.290. BMRR is composed of three distinct technical branches: regulation, closure and reclamation. It is the mission of BMRR to ensure that Nevada's waters are not degraded by mining operations and that the lands disturbed by mining operations are reclaimed to safe and stable conditions to ensure a productive post-mining land use. These laws and regulations are the primary pieces of legislation governing the Companys reclamation obligations. International Operations The Companys exploration properties, primarily located in El Salvador, are governed by existing local environmental laws, though the Company elects in certain circumstances to exceed its obligations under local environmental law and comply with internationally accepted environmental standards. The Companys exploration programs are designed according to industry best practices to have minimal to no impact on flora, fauna and surface or underground water sources. Temporary disturbances (temporary access roads, drill pads, mud pits, hand dug trenches, impacts on existing infrastructure) are reclaimed and repaired. Using the same methods required for structural studies at dam site and large construction sites, drill holes are capped with either a 50 meter grout cap or are completely filled with grout, depending on the geologic environment. The temporary access trails, drill pads and mud sumps are reclaimed by filling in ruts, holes and pits, re-contouring any banks or steep cuts, building water diversion ditches to control runoff and planting fast growing, native grasses to stabilize the ground. Trenches are refilled and replanted in a like manner, and fence barriers are occasionally built to control livestock movement around reclaimed areas. Permanent or long term disturbances such as roads, buildings, wells, walls and fences, gates, etc. are constructed with erosion controls and stability measures including, as necessary, badenes, rock retaining walls, water diversion ditches, drain pipes and/or stabilizing vegetation, and are constructed to standards exceeding local regulation. Often, local tree varieties are harvested then replanted in the disturbed areas when it does not conflict with normal local usage. All areas of reclamation and construction are monitored on an annual basis. If additional repair is required because of the initial construction, it is repaired until the area gains stability. The Companys professional environmental staff has volunteered and assisted the local authorities in evaluating other arms-length environmental, geologic, hydrologic, disaster sites around the immediate communities by conducting land slide analysis, ground water studies, surface water studies, land fill site studies, helping to evaluate other industrial waste sites, fire prevention, disease control, disaster relief preparedness and first aid. Contractors to the Company are required to use certified, non-polluting, non-toxic additives in drilling programs and comply with international work and safety standards and procedures. These issues are routinely monitored by Company employees under the direction of the local environmental and safety managers. Environmental compliance and risk are regularly assessed by third party contractors specializing in mining and exploration risk management. In addition, the Company has established showcase programs for environmental protection, waste management and reforestation in order to educate workers and local populace on common best practice measures for a healthier, cleaner and safer living and working environment. Ongoing reclamation activities associated with the Companys exploration stage properties are expensed as exploration in the period incurred.

- 32 - Proposed Transactions Pacific Rim is continually reviewing project acquisitions and other opportunities that could enhance shareholder value. There are currently no transactions in process that would affect the financial condition, results of operations or cash flows of the Company. Related Party Transactions The Company received accounting services from an accounting firm in which an Officer of the Company is a partner. The total accounting and tax fees paid were Cdn$152,223. ITEM 4A.  UNRESOLVED STAFF COMMENTS Not applicable ITEM 5.  OPERATING AND FINANCIAL REVIEW AND PROSPECTS Critical Accounting Estimates The preparation of financial statements in conformity with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management estimates include the carrying value of mineral properties and property, plant and equipment, bullion, closure costs and stock based compensation. Factors that could affect these estimates include risks inherent in mineral exploration and development, changes in reclamation requirements, and changes in government policy. The carrying value of the El Dorado property reflects its acquisition cost, which was based on an estimate of the propertys mineral resource at the time of the acquisition. This resource estimate was filed as a National Instrument 43-101 compliant technical report in February 2002. It has been superseded by subsequent resource estimates, the most recent of which was completed in January 2008. The Companys activities in El Salvador are subject to the effects of changes in legal, tax and regulatory regimes, national and local political issues, labour and economic developments and government bureaucracy. PRES has experienced lengthy delays in the government of El Salvadors processing of the El Dorado exploitation concession application with no resolution to date, which, along with other factors beyond the control of PRES, could adversely impact operations in El Salvador or result in the impairment of the El Dorado property in the future; such impairment could be material. PRES has commenced a legal claim under CAFTA. If PRES is unsuccessful in obtaining a permit for El Dorado or in its CAFTA claim, or other factors beyond the control of the Company, such factors could adversely impact operations in El Salvador or result in the impairment of the El Dorado property in the future; such impairment could be material. As at April 30, 2010, management of the Company determined that impairment indicators existed on its El Dorado project and completed an impairment assessment on this project. The current economic environment, the decline in the Companys stock price and the difficulty in obtaining a permit were considered as impairment indicators. As part of their impairment evaluation, management considered a number of factors, including the Companys share price at April 30, 2010 and current gold prices along with the Companys 2005 pre-feasibility study. Based on this impairment evaluation no impairment of the El Dorado project was identified as of April 30, 2010. To date, the Companys discussions with its legal counsel representing the Company in the CAFTA arbitration have not resulted in a determination of any material impairment in the carrying value of the Company concessions. The Company re-evaluates the carrying values of property, plant and equipment when events or changes in circumstance indicate that carrying values may not be recoverable. If it is determined that the estimated net recoverable amount based on non-discounted cash flows is less than the carrying value, a write-down to the estimated fair value is made by a charge to earnings. The Company makes significant assumptions and estimates in determining the fair market value of stock-based compensation granted to employees and non-employees and the value attributed to various warrants and broker warrants issued on financings, which have an effect on the stock-based compensation expense recognized and the contributed surplus and share capital balances on the Companys balance sheet. Using the Black-Scholes Option Pricing Model, management has made estimates of the life of stock options and warrants, the expected volatility and the expected dividend yields that could materially affect the fair market value of these securities. The estimates were chosen after reviewing the historical life of the Companys options and analyzing share price history to determine volatility.

- 33 - As part of the sale of its interest in Denton-Rawhide (readers are referred to the Companys 2009 Annual Report), the Company has provided a guarantee on 49% of any reclamation and closure costs in the event that reclamation and closure costs were to exceed $7.0 million. Kennecott has estimated a total of $4.9 million for these expenditures under the proposed plan. Changes in Accounting Policies Effective May 1, 2009 the Company adopted EIC-173 Credit Risk and the Fair Value of Financial Assets and Financial Liabilities. This guidance clarified that an entitys own credit risk and the credit risk of the counterparty should be taken into account in determining the fair value of financial assets and financial liabilities including derivative instruments. The Company has evaluated the new section and determined that adoption of these new requirements did not have a significant impact on the Companys consolidated financial statements. Effective May 1, 2009 the Company adopted CICA HB Section 3064, Goodwill and Intangible Assets, which replaces CICA HB Section 3062, Goodwill and Intangible Assets, and CICA HB Section 3450, Research and Development Costs, and amendments to Accounting Guideline (AcG) 11, Enterprises in the Development Stage, EIC-27, Revenues and Expenditures during the Pre-operating Period and CICA HB Section 1000, Financial Statement Concepts. The standard intends to reduce the differences with International Financial Reporting Standards (IFRS) in the accounting for intangible assets and results in closer alignment with U.S. GAAP. The objectives of Section 3064 are to reinforce the principle-based approach to the recognition of assets only in accordance with the definition of an asset and the criteria for asset recognition; and clarify the application of the concept of matching revenues and expenses such that the current practice of recognizing assets that do not meet the definition and recognition criteria are eliminated. The standard also provides guidance for the recognition of internally developed intangible assets (including research and development activities), ensuring consistent treatment of all intangible assets, whether separately acquired or internally developed. The Company has evaluated the new section and determined that the adoption of these new requirements did not have a significant impact on the Companys consolidated financial statements. On March 27, 2009, the CICA approved EIC-174 Mining Exploration Costs. This guidance clarified that an entity that has initially capitalized exploration costs has an obligation in the current and subsequent accounting periods to test such costs for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. The Company has evaluated the new section and determined that adoption of these new requirements did not have a significant impact on the Companys consolidated financial statements. Recent accounting pronouncements not yet adopted The Canadian Accounting Standards Board (AcSB) has announced its decision to replace Canadian generally accepted accounting principles (GAAP) with International Financial Reporting Standards (IFRS) for all Canadian Publicly Accountable Enterprises (PAEs). The effective changeover date is May 1, 2011, at which time Canadian GAAP will cease to apply for Pacific Rim and will be replaced by IFRS. Following this timeline, the Company will issue its first set of interim financial statements prepared under IFRS in the first quarter of 2012 ending July 31, 2011 including comparative IFRS financial results and an opening balance sheet as at May 1, 2010. The first annual IFRS consolidated financial statements will be prepared for the year ended April 30, 2012 with restated comparatives for the year ended April 30, 2011. Management has developed a project plan for the conversion to IFRS based on the current nature of operations. The conversion plan is comprised of three phases: 1) Scoping phase which will assess the overall impact and effort required by the Company in order to transition to IFRS, 2) Planning phase which will include a detailed analysis of the conversion process and implementation plan required for disclosure for the Companys first quarter 3) Transition phase which will include the preparation of an IFRS compliant opening balance sheet as at May 1, 2010, any necessary conversion adjustments and reconciliations, preparation of a fully compliant pro forma financial statements including all note disclosures and disclosures required for the MD&A. Management has completed phase one, IFRS Scoping phase, and is now advancing through phase two, the Planning stage. Most adjustments required on transition to IFRS will be made, retrospectively, against opening retained earnings as of the date of the first comparative balance sheet presented based on standards applicable at that time. IFRS 1, First-Time Adoption of International Financial Reporting Standards, provides entities adopting IFRS for the first time with a number of optional exemptions and mandatory exceptions, in certain areas, to the general requirement for full retrospective application of IFRS. During the second quarter of 2011, management will conduct an IFRS educational session for the Audit Committee and the Board of Directors which will focus on the key issues and transitional choices under IFRS 1 applicable to the Company. Set out below are the most significant areas management has identified to date, where changes in accounting policies may have the highest potential impact on the Companys consolidated financial statements based on the accounting policy choices approved by the Audit Committee and Board of Directors.


---

- 34 - Audit Committee and Board of Directors. In the period leading up to the changeover in 2011, the AcSB has ongoing projects and intends to issue new accounting standards during the conversion period. As a result, the final impact of IFRS on the Companys consolidated financial statements can only be measured once all the IFRS accounting standards at the conversion date are known. Management will continue to review new standards, as well as the impact of the new accounting standards, between now and the conversion date to ensure all relevant changes are addressed. Impairment Assets Canadian GAAP generally uses a two-step approach to impairment testing: first comparing asset carrying values with undiscounted future cash flows to determine whether impairment exists; and then measuring any impairment by comparing asset carrying values with discounted cash flows. International Accounting Standard (IAS) 36, Impairment of Assets uses a one-step approach for both testing and measurement of impairment, with asset carrying values compared directly with the higher of fair value less costs to sell and value in use (which uses discounted future cash flows). This may potentially result in write downs where the carrying value of assets were previously supported under Canadian GAAP on an undiscounted cash flow basis, but could not be supported on a discounted cash flow basis. Currently the Company has significant assets, which based on initial assessment of these significant assets, no impairment charge is expected on transition to IFRS. Share Based Payments IFRS and Canadian GAAP largely converge on the accounting treatment for share  based transactions with only a few differences. Canadian GAAP allows either accelerated or straight line method of amortization for the fair value of stock options under graded vesting. Currently, the Company is using the accelerated amortization method and therefore the adoption of IFRS 2 is not expected to have an impact on the Companys financial statements. Under IFRS, the estimate for forfeitures must be made when determining the number of equity instruments expected to vest, while under Canadian GAAP forfeitures can be recognized as they occur. The Company will begin using the estimate of forfeitures starting May 1, 2010 when determining the number of equity instruments expected to vest. Upon adoption of IFRS 2, the Company will be fully compliant with the new standard and the adoption is not expected to have an impact on the financial statements. Exploration and Evaluation Assets Under the Companys current accounting policy, only the acquisition costs of mineral properties are capitalized. Upon adoption of IFRS, the Company has to determine the accounting policy for exploration and evaluation assets and will need to determine whether they should be classified as intangible or tangible assets. The Company is currently in compliance with the International Accounting Standards Board (IASB) Framework. Upon adoption of IFRS 6, Exploration and Evaluation of Mineral Properties, the Company will be fully compliant with the new standard. The adoption is expected to have an impact on the financial statements as the mineral property acquisition costs for El Salvador will now be included in a separate line on the Statement of Financial Position rather than as part of Property, Plant & Equipment. Property, Plant and Equipment Under IFRS, Property, Plant and Equipment (PP&E) can be measured at fair value or at cost while under Canadian GAAP, the Company has to carry PP&E on a cost basis and the revaluation is prohibited. Upon adoption of IFRS, the Company has to determine whether to elect a cost model or revaluation model. Management has yet to decide on which model to adopt. Currently, aside from the mineral property, the Company has only a small amount of equipment and vehicles capitalized as property, plant and equipment. As a result there will not be a significant impact on the adoption of either IFRS model on the Companys financial statements except for the reallocation of the mineral property costs to a separate line. In accordance with IAS 16 Property, Plant and Equipment, upon acquisition of significant assets, the Company will need to allocate an amount initially recognized in respect of an asset to its component parts and accounts for each component separately when the components have different useful lives or the components provide benefits to the entity in a different pattern.


---

- 35 - Foreign Currency IFRS requires that the functional currency of each entity in the consolidated group be determined separately in accordance with IAS 21 and the entitys financial results and position should be measured using the currency of the primary economic environment in which the entity operates (the functional currency). Based on the cash outflows or expenses the functional currency is most likely Canadian dollars for Pacific Rim Mining Corp. and United States dollars for the El Salvador companies and the United States companies. If it is determined that the Canadian entity has a Canadian dollar functional currency, the Canadian entity will need to be translated into the United States dollar reporting currency using the current rate method which will result in a cumulative translation adjustment in the Accumulated Other Comprehensive Income in the Equity section of the Statement of Financial Position. As events and conditions relevant to the Company change, it will re-consider the primary and secondary indicators, as described in IAS 21, in determining the functional currency for each entity. Going forward under IFRS, management will assess the appropriate functional currency based on existing circumstances which may have a significant impact on the Companys consolidated financial statements prepared under IFRS. Future Income Taxes Like Canadian GAAP, deferred income taxes under IFRS are determined using the liability method for temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes, and by generally applying tax rates applicable to the Company to such temporary differences. Deferred income taxes relating to temporary differences that are in equity are recognized in equity and under IFRS subsequent adjustments thereto are backward traced to equity. IFRS prohibits recognition where deferred income taxes arise from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting nor taxable net earnings. As a result, when the Company adopts IAS 12, Income Taxes, the future income tax liability will have a zero balance with the adjustment flowing through the opening retained earnings . As the Company elects and approves the IFRS accounting policy for each of the areas above, management will determine and disclose impact of the IFRS adoption at the transition date on our financial statements. The International Accounting Standards Board will also continue to issue new accounting standards during the conversion period and, as a result, the final impact of IFRS on the Companys consolidated financial statements will only be measured once all the IFRS applicable accounting standards at the conversion date are known. Based on management assessment of the information system currently used by the Company, all information required to be reported under IFRS will be available with minimal system changes. One of the more significant impacts identified to date of adopting IFRS is the expanded presentation and disclosures required. Disclosure requirements under IFRS generally contain more breadth and depth than those required under Canadian GAAP and, therefore, will result in more extensive note references. The Company is continuing to assess the level of presentation and disclosures required to its consolidated financial statements. In October 2008, the CICA issued Handbook section 1582, Business Combinations, which establishes new accounting for business combinations. This is effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after May 1, 2011. The Company has elected to early adopt this standard effective on May 1, 2010. The adoption of this standard did not have any impact on the Companys consolidated financial statements. In October 2008, the CICA issued Handbook section 1602, Non-controlling Interests, to provide guidance on accounting for non-controlling interests subsequent to a business combination. The section is effective for fiscal years beginning on or after May 1, 2011. A.
     Operating Results
  Pacific Rim is an exploration company that relies on cash and cash equivalents to fund its exploration and general and administrative expenses.


---

- 36 - For the fiscal year ended April 30, 2010, Pacific Rim recorded a loss for the period of $(5.0) million or $(0.04) per share, compared to a loss of $(6.3) million or $(0.05) per share for the fiscal year ended April 30, 2009 and $(12.7) million or $(0.11) per share for the fiscal year ended April 30, 2008. The decrease in net loss for fiscal 2010 compared to fiscal 2009 is primarily related to significantly decreased exploration expenses, offset in part by significantly lower net income from the Denton-Rawhide joint venture as a result of the sale by the Company of its interest in the joint venture during fiscal 2009. The decrease in net loss for fiscal 2009 compared to fiscal 2008 (a difference in net loss of $6.4 million) was a result of a substantial decrease in exploration costs combined with an increase in income from discontinued operations (the Denton-Rawhide Joint Venture) year over year. During fiscal 2010 the Companys cash and cash equivalents increased by $0.05 million from $1.28 million at April 30, 2009 to $1.33 million at April 30, 2010. The Company held no bullion at April 30, 2010 (unchanged from January 31, 2010) compared to bullion (held by the Company and not yet sold) valued at $1.2 million at April 30, 2009. Current assets were $ 1.4 million at April 30, 2010 (from $2.4 million at January 31, 2010) compared to $2.6 million at April 30, 2009, a decrease of $0.2 million since the end of the Companys previous fiscal year. This decrease reflects bullion sales to fund the expenditures of cash on exploration expenses and project generation efforts, general and administrative costs associated with maintaining a public company, and expenditures related to advancing the CAFTA action, offset by the proceeds of a private placement equity financing undertaken by the Company during the third quarter of fiscal 2010. At April 30, 2010 the Company had current liabilities of $1.6 million compared to $0.6 million at April 30, 2009. The $1.0 million year over year increase in current liabilities is due to a $1.0 million increase in accounts payable ($1.6 million at April 30, 2010, of which $1.1 million is due to one vendor associated with PacRims CAFTA action). Future income tax liability, related to PacRims investment in El Salvador, did not change between the fiscal 2009 and fiscal 2010 year ends and at April 30, 2010 was valued at $1.0 million. Currently, Pacific Rim has no long-term debt. The $1.2 million decrease in current assets combined with the $1.0 million increase in current liabilities, resulted in a $2.2 million reduction in working capital from $2.0 million at the end of fiscal 2009 to $(0.2) million at the end of fiscal 2010. Expenses Due to the cessation of the El Dorado drilling program in July 2008 and the reduction of other exploration expenses at all of the Companys projects, exploration expenditures decreased significantly over the past three fiscal periods, from $11.8 million in fiscal 2008 and $5.5 million in fiscal 2009 to $1.8 million in fiscal 2010. General and administrative expenses, which have trended higher over the past several years because of higher regulatory and legal costs of complying with United States and Canadian reporting and regulatory requirements, increased legal expenses, and one-time severance payments made in fiscal 2008 to key personnel, were reduced in fiscal 2010 due to reduced staffing costs as well as the generally lower level of business activity undertaken by the Company. General and administrative costs were $1.4 million in fiscal 2010 compared to $3.7 million in fiscal 2009 and $3.5 million in fiscal 2008. During fiscal 2010 the Company realized a $0.6 million gain on the sale of bullion, and a $0.2 million financing expense associated with the extension of warrants issued during the 2008 financing, for which there were no comparable items during either of fiscal 2009 or 2008. The Company booked a negligible foreign exchange loss of $0.02 million during fiscal 2010 compared to a loss of $0.2 million during fiscal 2009 and a gain of $0.4 million during fiscal 2008, primarily reflecting the impact of the US-Canadian dollar exchange rate on the Companys Canadian dollar-denominated investments on hand. Unusual Items During fiscal 2010 the Company received income of $0.04 million from the Denton-Rawhide operation compared to $3.2 million and $1.5 million during fiscal 2009 and fiscal 2008 respectively. Income from the Denton-Rawhide operation, in which the Company was a participant until December 31, 2008 is primarily related to the production of gold and silver. During fiscal 2008 the Company recovered $1.4 million on its investment in the Andacollo Mine. As this item represented the final of three staged payments on the sale of the mine, there were no comparable recoveries booked during fiscal 2009 or fiscal 2010. Summary As a result of significantly reduced exploration expenditures and decreased staffing levels associated with its reduction in exploration activity, partially offset by greatly reduced income from the Denton-Rawhide Joint Venture, the Companys loss for fiscal 2010 was reduced to $(5.0) million or $(0.04) per share from previous fiscal periods ($(6.3) million or $(0.05) per share for fiscal 2009 and $(12.7) million or $(0.11) per share for fiscal 2008.

  The Company has typically realized a net quarterly loss. Exploration expenses have generally decreased over the past eight quarters, since the Company elected to significantly reduce exploration in El Salvador in July 2008. Likewise, the Company made significant cuts to staffing levels during Q2 2009 and Q3 2009, which led to lower general and administrative costs. However, in the past four quarters, expenses related to the CAFTA action have significantly increased, offsetting the cost savings brought about by staffing cuts. Income from discontinued operations (the Denton-Rawhide joint venture) varied substantially quarter to quarter in prior periods. During Q2 2009 the Company received payment for the sale of its 49% interest in the operation and during Q3 2009 continued to participate in the proceeds of gold and silver production from the operation, which led to a notable increase in income from this discontinued operation during those two periods. Since Q1 2010 the Company has booked negligible income from discontinued operations. Net loss for each of the past 8 quarterly periods shows no discernable trend, which is largely a function of the previously significant variability in income from discontinued operations and rising costs related to the CAFTA action. Fourth Quarter Fiscal 2010 The Companys loss for the fourth quarter of fiscal 2010 was higher than any of the previous quarters during fiscal 2010, as a result of increased expenditures related to the CAFTA action, particularly preparations for the Preliminary Objection hearing held on May 31 and June 1, 2010 and increased exploration expenditures related to project generation initiatives. As the Companys participation in the Denton-Rawhide Joint Venture is completed, the Company received no income from discontinued operations to offset these expenses as it has in previous quarters, albeit only marginal amounts during fiscal 2010. The Companys fiscal 2010 fourth quarter results presented above are based on interim consolidated financial statements that have been prepared in accordance with Canadian generally accepted accounting principles (Canadian GAAP). The Companys reporting currency is the United States (U.S.) dollar and all monetary amounts are stated in U.S. dollars unless otherwise noted. Impact on Operations as a Result of Governmental Factors The Companys operations are primarily focused on the exploration for gold and silver and its sole material project, the El Dorado property, is located in El Salvador. The Company has experienced significant delays in the receipt of environmental and mining permits necessary to advance the El Dorado project further. See Item 4 Property, Plant and Equipment, and specifically El Salvador Mining Regime and El Dorado Property  CAFTA Actionfor information related to El Salvadors mining law, the Companys actions to date to comply with this law and a legal action that the Company has commenced under CAFTA. The receipt of necessary permits, or lack thereof, could have a material impact on the Companys operations. B.
     Liquidity and capital resources
  Liquidity During fiscal 2010 the Companys cash and cash equivalents increased by $0.05 million from $1.28 million at April 30, 2009 to $1.33 million at April 30, 2010. The Company held no bullion at April 30, 2010 compared to bullion (held by the Company and not yet sold) valued at $1.2 million at April 30, 2009. Current assets were $ 1.4 million at April 30, 2010 compared to $2.6 million at April 30, 2009, a decrease of $0.2 million since the end of the Companys previous fiscal year. This decrease reflects bullion sales to fund the expenditures of cash on exploration expenses and project generation efforts, general and administrative costs associated with maintaining a public company, and expenditures related to advancing the CAFTA action, offset by the proceeds of a private placement equity financing undertaken by the Company during the third quarter of fiscal 2010.

- 38 - Cash Flow Used For Operating Activities The Companys loss before discontinued operations was $(5.0) million in fiscal 2010 compared to $(9.4) million in fiscal 2009 and $(15.7) million in fiscal 2008. These losses were offset by a number of non-cash items including, notably: stock-based compensation of $0.4 million in fiscal 2010 compared to $0.6 million in fiscal 2009 and $1.0 million in fiscal 2008; shares issued for property option payments of $nil during fiscal 2010 compared to $0.3 million during fiscal 2009 and $0.2 million in fiscal 2008; $1.0 million in future income tax booked during fiscal 2008 for which there is no comparable item in fiscal 2009 and fiscal 2010; $0.2 million in financing costs related to the extension of the expiry date of warrants issued in fiscal 2008; a change in accounts payable and accrued liabilities of $0.9 million for fiscal 2010 compared to $(0.7) million during fiscal 2009 and $0.4 million during fiscal 2008; and $1.2 million change in bullion during fiscal 2010 for which there is no comparable item during fiscal 2009 or fiscal 2008. As a result, cash flow used for operating activities was $(2.2) million in fiscal 2010 compared to $(9.2) million in fiscal 2009 and $(12.9) million in fiscal 2008. Cash Flow Provided by Investing Activities During fiscal 2009 and fiscal 2008 the Company made net redemptions from short term investments ($4.2 million and $3.8 million respectively), compared to $nil during fiscal 2010. In fiscal 2008 the Company made purchases of property plant and equipment of $1.2 million compared to a negligible amount in each of fiscal 2009 and fiscal 2010. Proceeds from the sale of discontinued operations were $nil during fiscal 2010 compared to $1.8 million for fiscal 2009 (related to the sale of the Denton-Rawhide asset) and $1.4 million for fiscal 2008 (related to the sale of the Andacollo mine). As a result, cash flow provided by investing activities was $(0.01) million during fiscal 2010 compared to $6.0 million during fiscal 2009 and $4.0 million during fiscal 2008. Cash Flow Provided by Financing Activities The Company realized $2.2 million in cash flow from financing activities during fiscal 2010, compared to $nil during fiscal 2009 and $6.9 million in fiscal 2008. The fiscal 2010 and fiscal 2008 financing cash flow amounts are related to the issuance of common shares of the Company under January 2010 and February 2008 equity financings (details below) as well as the exercise of employee stock options (282,500 shares at an average price of Cdn $1.30 per share during fiscal 2008 and 16,666 shares at an average price of Cdn $0.17 per share during fiscal 2010. During fiscal 2010, the Company announced and closed a private placement financing through which a total of Cdn $2,355,000 was raised through the issuance of 11,775,000 units (Units). Each Unit consists of one common share in the Company and one non-transferable share purchase warrant (Warrant) that entitles the holder to acquire one additional common share of the Company at a price of Cdn $0.30 for a period of 36 months following the closing of the financing, which occurred on January 14, 2010. Pacific Rim reserves the right to accelerate the exercise period of the Warrants should its common stock trade above CDN $0.40 for 20 consecutive trading days. The Units were subject to a four-month trading restriction that began on the day of issuance and expired on May 15, 2010. The Company also issued 483,000 Units (the Finders Units) to certain finders (the Finders) in connection with the private placement, in payment of a finders fee of 6% of the proceeds raised from subscribers introduced by the Finders, and issued 483,000 warrants to Finders (the Finders Warrants) representing 6% of the total number of Units sold to purchasers introduced by the Finders. During fiscal 2008, the Company announced and closed a private placement financing through which a total of CDN $7,046,550 was raised through the issuance of 6,711,000 units (Units). Each Unit consists of one common share in the Company and one non-transferable share purchase warrant (Warrant) that entitles the holder to acquire one additional common share of the Company at a price of CDN $1.35 for a period of 18 months following the closing of the financing, which occurred on February 29, 2008. Pacific Rim reserves the right to accelerate the exercise period of the Warrants should its common stock trade above CDN $2.00 for 20 consecutive trading days. The Units were subject to a four-month trading restriction that began on the day of issuance and expired on June 30, 2008. A finders fee of 7% commission was paid and 7% agent warrants were issued to the finders in respect of certain placees introduced by such finders. Capital Resources and Financial Condition At April 30, 2010, the book value of the Companys current assets stood at $1.4 million, compared to $2.6 million at April 30, 2009, a reduction of $1.2 million. The decrease in current assets is primarily a result of the sale of bullion (for cash) and subsequent cash expenditures as outlined in Section 6 above, offset by the addition of cash from the sale of securities under a private placement financing as outlined in Section 6.3 above. Property, plant and equipment balances at April 30, 2010 were marginally lower than the April 30, 2009 balance ($5.5 million and $5.6 million respectively). As a result, the Companys total assets at the end of fiscal 2010 were $6.9 million compared to $8.2 million at the end of fiscal 2009.

- 39 - At April 30, 2010 the Company had current liabilities of $1.6 million compared to $0.6 million at April 30, 2009. The $1.0 million year over year increase in current liabilities is due to a $1.0 million increase in accounts payable ($1.6 million at April 30, 2010, of which $1.1 million is due to one vendor associated with PacRims CAFTA action). Future income tax liability, related to PacRims investment in El Salvador, did not change between the fiscal 2009 and fiscal 2010 year ends and at April 30, 2010 was valued at $1.0 million. Currently, Pacific Rim has no long-term debt. The $1.2 million decrease in current assets combined with the $1.0 million increase in current liabilities, resulted in a $2.2 million reduction in working capital from $2.0 million at the end of fiscal 2009 to $(0.2) million at the end of fiscal 2010. The Company does not intend to resume significant exploration programs in El Salvador until such time as the El Dorado environmental permit and exploitation concession are received. The Company can not judge if or when the required permits will be received and is not currently planning any exploration programs for its El Dorado, Santa Rita and Zamora-Cerro Colorado properties for fiscal 2011 beyond what is necessary to keep all of its exploration licences in good standing. Should the required permits be granted, the Company will evaluate its options for resuming full scale exploration work designed to advance its El Salvador projects. The Company intends to continue its project generation initiatives with the aim of acquiring a new exploration project, outside of El Salvador, during fiscal 2011. The Company plans on conducting low cost field work, technical and legal due diligence on projects it is currently evaluating and to seek new prospects for staking or property acquisitions that fit its exploration focus. The Company anticipates that its fiscal 2011 exploration plans as outlined above will cost approximately $1.0 million. The Company anticipates requiring financing during fiscal 2011 in order to fund its exploration programs. The Companys general and administrative costs are expected to remain stable during fiscal 2011, reflecting, lower staffing costs as a result of personnel reductions undertaken in fiscal 2009 and fiscal 2010. Expenditures related to PacRims CAFTA action are expected to continue at present or modestly higher levels during fiscal 2011, and are dependant on the level of arbitration activity. The Company has currently accumulated a liability of approximately $1.1 related to the CAFTA action, which is partly responsible for the Companys current working capital deficit. The Company is currently discussing vendor-specific alternative financing opportunities that will reduce this accounts payable position. The Company may also seek financing during fiscal 2011 to remediate its working capital deficit, for general working capital expenses and to finance acquisition of and/or exploration programs on a new project. The business of mining and exploration involves a high degree of risk and there can be no assurance that current exploration programs will result in profitable mining operations. The Company has no source of revenue, and will require additional cash to continue fund legal, exploration and administration expenses. The Company as at April 30, 2010 had a current working capital deficit of $0.2 million and had incurred losses since inception and has an accumulated deficit of $86.1 million at April 30, 2010. The Companys ability to continue operations and exploration activities as a going concern is dependent upon its ability to obtain additional funding. The Company will need to raise sufficient funds to support ongoing exploration and administration expenses as well as its costs under PacRims CAFTA arbitration. While the Company has been successful in obtaining its required funding in the past, there is no assurance that sufficient funds will be available to the Company in the future. The Company has no assurance that such financing will be available or be available on favorable terms. Factors that could affect the availability of financing include the progress and results of the El Dorado project and its permitting application, the resolution of international arbitration proceedings over the non-issuance of permits in El Salvador, the state of international debt and equity markets, investor perceptions and expectations and the global financial and metals markets. Additional financing will require, but may not be limited to, the issuance of additional equity On November 12 the Company announced it received notice from the NYSE Amex that, based on their review of the Companys fiscal 2010 first quarter results, the Company is not in compliance with Section 1003(a)(iii) of the NYSE Amex Company Guide, having at July 31, 2009 stockholders equity of less than $6,000,000 while sustaining losses from continuing operations and net losses in its five most recent fiscal years. In order to maintain listing of the Companys common shares on the NYSE Amex, the Company was required to submit a compliance plan to NYSE Amex addressing how it intends to regain compliance with Section 1003(a)(iii) by May 11, 2011, which plan was submitted on December 11, 2009. On February 11, 2010 (subsequent to the end of Q3 2010), the Company announced that it had received notice of acceptance of the plan by NYSE Amex. WithNYSE Amexs acceptance of the plan, the Companys NYSE Amex listing is expected to continue during the plan period, up to May 11, 2011, subject to periodic review to determine whether the Company is making progress consistent with the plan and conditions of NYSE Amex. If the Company is not in compliance with the continued listing standards at the end of the plan period, or if the Company does not make progress consistent with the plan during the period, then NYSE Amex may initiate delisting proceedings.

- 40 - The Companys common shares continue to trade on the NYSE Amex under the symbol PMU with the trading symbol extension BC to denote non-compliance with NYSE Amexs continued listing standards while the Plan period is in effect. The Companys common shares also continue to be listed on the TSX in Canada under the symbol PMU. The Company does not have any off-balance sheet arrangements. Outlook The Company will continue to curtail its exploration programs and expenditures in El Salvador until such time as PRES receives the El Dorado environmental permit and exploitation concession. The Company remains confident that it will either receive the El Dorado permit and mining concession or that it will be appropriately compensated. The Company believes the principal risk is its ability to fund the ongoing CAFTA action to a just conclusion. The Company anticipates expending approximately $1.0 million on exploration-related expenses during fiscal 2011, primarily on low-cost exploration work required to keep all of its El Salvador projects in good standing, limited community relations initiatives, and due diligence evaluation of new projects outside of El Salvador. This work will be revised should circumstances change and depending on the Companys success in acquiring a new exploration project, in which case exploration expenditures will likely increase, and/or financing opportunities. The Company anticipates requiring financing during fiscal 2011 in order to fund its exploration programs. The Companys general and administrative costs are expected to remain stable during fiscal 2011, reflecting, lower staffing costs as a result of personnel reductions undertaken in fiscal 2009 and fiscal 2010. Expenditures related to PacRims CAFTA action are expected to continue at present or modestly higher levels as during fiscal 2010, and are dependant on the level of arbitration activity. The Company is currently discussing vendor-specific alternative financing opportunities that will reduce its accounts payable and accrued liabilities, the majority of which are payable to a single vendor involved in the CAFTA action and/or for general working capital expenses and/or future expenses related to the CAFTA action. The Company will continue to seek opportunities for dialogue with the GOES aimed at resolving the El Dorado permitting situation. The Company and its subsidiaries have a well documented history of supporting local inhabitants and building relationships with all stakeholders. This is a key component of the Companys approach to exploration and development, and will continue in all jurisdictions in which it and its subsidiaries operate. Notwithstanding these diplomatic efforts, until resolved, PacRims CAFTA action is expected to proceed during fiscal 2011. The Company is currently awaiting the outcome of the Preliminary Objection hearing held on May 31 and June 1, 2010, which will determine the course of this arbitration going forward. The Company may seek traditional or alternative financing arrangements during fiscal 2011 specifically ear-marked for legal expenses. C.

     Trend Information
  While the Company does not have any producing mines, it is directly affected by trends in the metal industry. The El Dorado Gold Project, Santa Rita Gold Project and the ZamoraCerro Colorado Gold Project are all projects containing gold deposits. At the present time global metal prices are extremely volatile. Metal prices, driven by rising global demand, climbed dramatically and approached near historic highs over the past several years. The global economic and credit crisis has affected all industries, and the base metals sector has seen plummeting metal prices since October 2008 with some recovery. The effect of high metal prices had a significant positive impact on the ability to raise equity capital and to attract interest from potential sources of required capital to fund the costs of placing the El Dorado Gold Project into production; however, the increasing metal prices also contributed to significant increases in the capital costs of many projects including El Dorado. Overall market prices for securities in the mineral resources sector and factors affecting such prices, including base metal prices, political trends in the countries such companies operate, and general economic conditions, may have an effect on the terms on which financing is available to the Company, if at all. Refer to Risk Factors for further information on uncertainty or items affecting the business or nature of business of the Company. E.
     Off-Balance Sheet Arrangements
     - 41 - The Company has no material off-balance sheet arrangements such as guarantee contracts, contingent interest in assets transferred to an entity, derivative instrument obligations and any obligations that trigger financing, liquidity, market or credit risk to the Company. F.

     The stock options granted to Thomas Shrake, Steven Krause and William Gehlen, were valued in a currency other than the currency that the Company uses in its financial statements and has been translated herein at the rate of CDN$1.0656 for every US$1, which was the exchange rate on the day of the stock option grants.(2)
     The other compensation attributable to Steven Krause is calculated by multiplying his total salary paid by Avisar Chartered Accountants by the percentage of total Avisar billings attributable to the Company. During the 2010 fiscal year, Avisar Chartered Accountants charged the Company CDN$152,223 for accounting, tax and financial consulting services and has been translated herein at the rate of CDN$1.07321 for every US$1.(3)
     Mr. Shrakes official annual salary is US $250,000 per year. Since November 2008, in light of economic and market conditions, Thomas Shrake has voluntarily taken only US $180,000 in salary per year, representing 72% of his official salary. Incentive Plan Awards - Outstanding Share-Based Awards and Option-Based Awards On August 26, 2009, amendments to the Companys 2006 Evergreen Incentive Stock Option Plan (the 2006 Stock Option Plan) approved by the Directors on July 22, 2009, were ratified, confirmed and approved by the Shareholders. As a result, the 2006 Stock Option Plan has been superseded by the Amended 2006 Evergreen Incentive Stock Option Plan (the Amended Evergreen Plan). The 2006 Stock Option Plan has in the past been, and the Amended Evergreen Plan has and will be, used to provide share purchase options which are granted in consideration of the level of responsibility of the executive as well as his or her impact or contribution to the longer-term operating performance of the Company. In determining the number of options to be granted to the executive officers, the Board takes into account the number of options, if any, previously granted to each executive officer, and the exercise price of any outstanding options to ensure that such grants are in accordance with the policies of the Toronto Stock Exchange (TSX), and closely align the interests of the executive officers with the interests of the Shareholders. The following table sets forth information concerning all awards outstanding under incentive plans of the Company pursuant to which compensation that depends on achieving certain performance goals or similar conditions within a specified period, at the end of the most recently completed financial year, including awards granted before the most recently completed financial year, to each of the Named Executive Officers: Name

     This amount is the dollar value that would have been realized computed by obtaining the difference between the market price of the underlying securities at exercise and the exercise or base price of the options under the option-based award on the vesting date. On December 30, 2009, 165,000 options granted to Mr. Shrake, 125,000 options granted to Mr. Krause and 66,000 options granted to Mr. Gehlen on December 30, 2008, priced at Cdn$0.17 vested. No other previously granted options awarded to either Mr. Shrake, Mr. Krause or Mr. Gehlen vested or were exercised between May 1, 2009 and April 30, 2010. Messers. Shrake, Krause and Gehlen were granted stock options on January 27, 2010 (400,000, 250,000 and 200,000 options respectively) priced at CDN$0.21 with an expiry date of January 26, 2015. The options vest as to 1/3 on the grant date, and 1/3 on each of the subsequent two anniversaries of the grant date. The Companys closing market price on the TSX on January 27, 2010 (the grant date) was Cdn $0.20. Including previously awarded stock option grants, at April 30, 2010 Mr. Shrake held a total of 1,400,000 options (of which 962,000 are fully vested), Mr. Krause held a total of 500,000 options (of which 333,333 are fully vested) and Mr. Gehlen held a total of 650,000 options (of which 514,000 are fully vested). Pension Plan Benefits The Company does not have a pension plan that provides for payments or benefits to the Named Executive Officers at, following, or in connection with retirement. Termination and Change of Control Benefits The Company has a current employment agreement with Thomas Shrake, CEO, which includes termination and change of control benefits.
     - 45 - In the employment agreement, change of control is defined as any change in the effective control or direction of the Company and includes: (a)
     an acquisition of 20% or more of the voting rights attached to all outstanding shares of the Company by a person or combination of persons acting in concert by virtue of an agreement, arrangement, commitment or understanding; or(b)
     a change in the Companys officers or Directors, which alters the effective control or direction of the Company. An event of termination is defined in the employment agreement as the occurrence of any of the following events at any time after a change of control, without the executives written consent: (a)
     a change (other than changes that are clearly and exclusively consistent with a promotion) in the executives position or duties (including any position or duties as a director of the Company), responsibilities (including, without limitation, the person(s) to whom the executive reports, and who report to the executive), title or office in effect immediately prior to the change of control, which includes any removal of the executive from or any failure to re-elect or re-appoint the executive to any such positions or offices;(b)
     any failure by the Company to increase the executives remuneration in a manner consistent (both as to frequency and as to percentage increase) with increases granted generally to the Companys other senior personnel;(c)
     the Company permanently relocating the executive to any place other than the location at which he reported to work on a regular basis immediately prior to the change of control;(d)
     the Company taking any action to deprive the executive of any material fringe benefits enjoyed by him immediately prior to the change of control or the Company failing to increase or improve such material fringe benefits on a basis consistent with increases or improvements granted to the Companys other senior personnel;(e)
     any breach of the Company of any provision of the employment agreement;(f)
     the good faith determination by the executive that, as a result of the change of control or any action or event thereafter, the executives status or responsibility in the Company has been diminished or the executive is effectively being prevented from carrying out his duties and responsibilities as they existed immediately prior to the change of control; or(g)
     failure by the Company to obtain, in a form satisfactory to the executive, an effective assumption of its obligations hereunder by a successor to the Company, including a successor to a material portion of its business. If, as a result of a change of control of the Company, Mr. Shrake experiences an event of termination as described above, Mr. Shrake is entitled to a severance payment of 24 months salary (based on his official annual salary of US$ 250,000) and is able to exercise any stock options previously granted within 45 business days in the event of termination after a change of control. Steven Krause has a consulting agreement with the Company which includes a change of control clause. In this consulting agreement, change of control means the acquisition by any person or by any person and joint actor, whether directly or indirectly, of voting securities as defined in the Securities Act of British Columbia, as amended from time to time (the Securities Act), which, when added to all other voting securities of the Company at the time held by such person or by such person and a person acting jointly or in concert with another person as that phrase is interpreted by the Securities Act, totals for the first time not less than fifty percent (50%) of the outstanding voting securities of the Company or the votes attached to those securities are sufficient, if exercised, to elect a majority of the Board of Directors. Should a change of control occur, all outstanding stock options held by Mr. Krause will become fully vested in accordance with the terms of the 2006 Evergreen Incentive Stock Option Plan, whereupon such options may be exercised in whole or in part by Mr. Krause. William Gehlen has an employment agreement with a subsidiary of the Company that includes termination and change of controlbenefits.. If, as a result of a change of control of the Company, Mr. Gehlen experiences an event of termination as defined above, Mr. Gehlen is entitled to a severance payment of 12 months salary, plus one months salary per year of service after one year, up to a maximum of 24 months salary, and is able to exercise any stock options previously granted within 30 calendar days in the event of termination after a change in control.
    - 46 - Other than as set forth above, neither the Company nor its subsidiaries has a contract, agreement, plan or arrangement that provides for payments to a Named Executive Officer following or in connection with any termination (whether voluntary, involuntary or constructive), resignation, retirement, a change of control of the Company or its subsidiaries, or a change in responsibilities of the Named Executive Officer following a change in control. Estimated Incremental Payment on Change of Control Under the terms of Thomas Shrakes employment agreement, the estimated incremental payment upon termination by the Company on a change of control of the Company, Mr. Shrake is entitled to receive approximately $360,000 (calculated as at April 30, 2010) based upon an amount equal to 24 months salary plus any amounts owed in respect of accrued vacation and the accelerated option value of his existing stock options. There are no provisions in Steven Krauses consulting agreement that would require the Company to make any payments to Mr. Krause upon a change of control of the Company. Under the terms of William Gehlens employment agreement, the estimated incremental payment upon termination by the Companys subsidiary on a change of control of the Company, Mr. Gehlen is entitled to receive approximately $240,000 (calculated as at April 30, 2010) based upon an amount equal to 12 months salary plus one months salary for every year of service beyond one year to a maximum of 24 months salary, plus any amounts owed in respect of accrued vacation and the accelerated option value of his existing stock options.

     Board Practices
  Corporate governance relates to the activities of the Companys board of directors (the Board), the members of which are elected by and are accountable to the shareholders, and takes into account the role of the individual members of management who are appointed by the Board and who are charged with the day to day management of the Company. The Board is committed to sound corporate governance practices which are both in the interest of its shareholders and contribute to effective and efficient decision making. National Policy 58-201 Corporate Governance Guidelinesestablishes corporate governance guidelines which apply to all public companies. The Company has reviewed its own corporate governance practices in light of these guidelines. In certain cases, the Companys practices comply with the guidelines; however, the Board considers that some of the guidelines are not suitable for the Company at its current stage of development and therefore these guidelines have not been adopted. National Instrument 58-101 Disclosure of Corporate Governance Practicesmandates disclosure of corporate governance practices, which disclosure is set out below.
     - 49 - Independence of Members of Board and Management Supervision by Board The Companys Board currently consists of five directors, a majority of whom are independent based upon the tests for independence set forth in Section 803 of the NYSE Amex Company Guide and National Instrument 52-110 Audit Committees(NI 52-110). Upon election to the Board at the shareholders meeting on August 25, 2010, the Board will include three (3) independent directors: Messrs. Myckatyn, Petrina, and Fagin. Mr. Shrake and Ms. McLeod-Seltzer are not considered independent as they are the President and Chief Executive Officer, and Board Chairman, respectively, of the Company. The Board facilitates the exercise of independent judgement in carrying out its responsibilities, by the effective supervision of management by the independent directors on an informal basis through active and regular involvement in reviewing and supervising the operations of the Company and through regular and full access to management. Further independent supervision is performed through the Audit Committee which is composed entirely of independent directors who meet regularly with the Companys auditors without management being in attendance. The independent directors hold meetings without the presence of non-independent directors on a quarterly basis and are also encouraged to meet at any time they consider necessary without any members of management, including the non-independent directors, being present. The Companys auditors, legal counsel and certain employees may be invited to attend. During the Companys most recently completed financial year, the independent directors met a total of three (3) times. Leadership is provided for the Boards independent directors through access to management and the independent operation of the Audit Committee, as discussed above, and through its Lead Director, Mr. Myckatyn. As Lead Director, Mr. Myckatyns role and responsibilities are to: (i)
     assist the Chairman to manage the Board and its committees in a manner that ensures that these relationships are effective and efficient and further the best interests of the Company;(ii)
     oversee the process of evaluation of the Board, its committees and individual Directors;(iii)
     act as the principal sounding board and counsellor for the Chairman;(iv)
     ensure that the Chairman is aware of concerns of the independent directors, shareholders and other stakeholders;(v)
     work with the Chairman to assist the Chairman in fulfilling her responsibilities in managing the Board;(vi)
     work with the Chairman to co-ordinate the agenda for Board meetings;(vii)
     chair and manage all meetings for the independent directors;(viii)
     attend committee meetings when it is appropriate to do so; and(ix)
     meet, from time to time, with the Chairman and the President and Chief Executive Officer to convey and discuss concerns of the independent directors.

  Board Mandate The mandate of the Board is to manage or supervise the management of the business and affairs of the Company and to act with a view to the best interests of the Company. The Board sets long-term goals and objectives for the Company to formulate the plans and strategies necessary to achieve those objectives and to supervise and offer guidance to the Companys senior management in their implementation. Although the Board has delegated to senior management personnel the responsibility for managing the day-to-day affairs of the Company the Board is ultimately responsible for all matters relating to the Company and its business. In fulfilling its mandate, the Board, among other matters, is responsible for reviewing and approving the Companys overall business strategies and its annual business plan; reviewing and approving the quarterly corporate and cash flow forecasts; reviewing and approving significant capital investments; reviewing major strategic initiatives to ensure that the Companys proposed actions accord with shareholder objectives; reviewing succession planning; assessing managements performance against approved business plans and industry standards; reviewing and approving the reports and other disclosure issued to shareholders; ensuring the effective operation of the Board; and safeguarding shareholders equity interests through the optimum utilization of the Companys capital resources. The Board expects management to efficiently implement its strategic plans for the Company in a professional, competent and ethical manner, to keep the Board fully apprised of its progress in doing so and to be fully accountable to the Board in respect to all matters for which it has been assigned responsibility. In addition to matters, which must by law or pursuant to the constating documents of the Company be approved by the Board, all matters of strategic importance to the Company are referred to the Board for prior review and approval. Any material expenditures or legal commitments, including without limitation debt or equity financings, acquisitions and divestitures by the Company, financial statements and major disclosure documents are subject to prior approval by the Board. The Board holds meetings on a regular basis to review the Companys strategy as well as to consider and approve particular matters. One of the Boards responsibilities is to review and, if thought fit, to approve opportunities as presented by management and to provide guidance to management. The Board expects management to operate the business of the Company in a manner that enhances shareholder value and is consistent with the highest level of integrity. Management is expected to execute the Companys business plan and to meet performance goals and objectives. The Board oversees the management of the Companys affairs directly and through its committees. The Board also meets to plan for the future growth of the Company; identify risks of the Companys business, thus ensuring the implementation of appropriate systems to manage these risks; monitor senior management; and ensure timely disclosure of material transactions. Frequency of Board meetings, as well as the nature of agenda items, change depending upon the state of the Companys affairs and in light of opportunities or risks that the Company faces. When necessary and appropriate, issues may be approved and adopted by the Board by way of written resolutions in accordance with applicable corporate law. Position Descriptions The Board has developed written position descriptions for the Chairman, the President and CEO and for the Directors at large. On a quarterly basis, the Board approves the operating and capital forecasts, and the Chairman and President and CEO are required to ensure the Company operates within those guidelines. Material departures must be approved by the Board. The Board is of the view that the respective corporate governance roles of the Board and management, as represented by the Chairman and President and CEO, are clear, and that the limits to managements responsibility and authority are well defined. The Board has not developed written position descriptions for the Chair of each Board committee. The Chairs of the Nominating and Compensation Committees, as well as the Health, Safety and Environmental Committee are responsible for calling the meetings of each Committee, establishing meeting agenda with input from management, and supervising the conduct of the meetings. The Chair of the Audit Committee has a clear mandate from the Board to carry out his responsibilities. Orientation and Continuing Education New directors are provided with a Board Manual, as reviewed and adopted by the Board, which contains comprehensive information and guidelines on the duties of the Board, and members of management, terms of reference for committees and policies adopted by the Board. New directors are given a full briefing by the Chairman of the Board and President and CEO. The President and CEO reports at each board meeting on the Companys activities and provides directors with a monthly written report. All directors are encouraged to contact senior management for updates at any time.
    - 51 - The Board currently does not provide continuing education for its directors. By using a Board composed of experienced professionals with a wide range of financial, legal, exploration and mining expertise, the Company ensures that the Board operates effectively and efficiently. Board members are encouraged to communicate with management, legal counsel and, where applicable, auditors and technical consultants of the Company; to keep themselves current with industry trends and developments and changes in legislation with managements assistance; and to attend related industry seminars and visit the Companys operations. Board members have full access to the Companys records. Ethical Business Conduct The Board has adopted a written Code of Conduct and Ethics by which it and all officers and employees of the Company abide. A copy of the Code of Conduct and Ethics is available for review on the Companys website and on SEDAR at www.sedar.com. In addition, the Board, through its meetings with management and other informal discussions with management, monitors in compliance with the Code of Conduct and Ethics and encourages a culture of ethical business conduct. The Companys high calibre management team promotes a culture of ethical business conduct throughout the Companys operations and is expected to monitor the activities of the Companys employees, consultants and agents in that regard. The Board encourages any concerns regarding ethical conduct in respect of the Companys operations to be raised, on an anonymous basis, with the President and CEO, the Chairman, or another Board member as appropriate. It is a requirement of applicable corporate law that Directors and senior officers who have an interest in a transaction or agreement with the Company promptly disclose that interest at any meeting of the Board at which the transaction or agreement will be discussed and, in the case of Directors, abstain from discussions and voting in respect to same if the interest is material. These requirements are also contained in the Companys Articles, which are made available to the Directors and senior officers of the Company.

  While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine if the Companys financial statements or disclosures are complete and accurate and are in accordance with GAAP and applicable rules and regulations. These are responsibilities of management and the independent auditors. Composition of the Audit Committee The members of the Audit Committee are David Fagin, William Myckatyn and Anthony Petrina. All of the members are financially literate and independent for the purposes of National Instrument 52-110 (NI 52-110). Mr. Fagin is a financial expert, in that he has an understanding of generally accepted accounting principles and financial statements; is able to assess the general application of accounting principles in connection with the accounting for estimates, accruals and reserves; has experience preparing, auditing, analyzing or evaluating financial statements that entail accounting issues of equal complexity to the Companys financial statements (or actively supervising another person who did so); has an understanding of internal controls and procedures for financial reporting and an understanding of audit committee functions. Mr. Fagin does not have an accounting designation; instead his expertise is derived from his high level involvement in the financial matters of public corporations almost continuously for at least 35 years. Mr. Fagin was involved in the valuation of oil and gas companies for ten years both as a consultant and a bank appraisal engineer (1958-68); President of a subsidiary of Rosario Resources Corporation, a NYSE company (1968-75), Executive Vice-President (1975-77) then President (1977-82) during which period he was intimately involved in financial and accounting matters. In 1982, he founded Fagin Exploration Company and worked closely with an accountant and auditors to maintain the records. From 1986 to 1991, Mr. Fagin was the President and Chief Operating Officer for Homestake Mining Corporation (NYSE), responsible for producing operations in six countries and was involved in decisions for corporate financial reporting. Between 1992 and 1996, Mr. Fagin was Executive Chairman of Golden Star Resources Ltd. (ASE and TSE) and managed all administrative matters including annual reports, audits and registration in Canada and the U.S. Since 1987, Mr. Fagin has served on boards and audit committees of several public companies including T. Rowe Price Mutual Funds, Golden Star Resources Ltd., Canyon Resources Corp. (recently acquired by Atna Resources Ltd.), Dayton Mining Corp. and the Company, where he was either Chairman or a member of each audit committee. He is currently a director of Atna Resources Ltd. and Golden Star Resources Ltd. Mr. Myckatyn does not have an accounting designation. However, Mr. Myckatyn is financially literate in that he has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Companys financial statements. Mr. Myckatyn has over 30 years experience in the mining industry. Mr. Myckatyn was Chairman, President and Chief Executive Officer of Dayton Mining Corporation (Dayton) from 1998 to April, 2002 where he led the restructuring of Dayton and its subsequent merger with the Company. Prior to 1998, Mr. Myckatyn was the President and CEO of Princeton Mining Corporation, overseeing completion in 1997 of the construction of the Huckleberry open-pit copper mine in British Columbia and the 1998 merger of the company with Imperial Metals Corporation. Mr. Myckatyn worked for Gibraltar Mines Limited from 1991 to 1996, initially as Mine Manager and ultimately as President and CEO as the company transitioned from being controlled by Placer Dome Inc. into an independent growth oriented public company, and through it acquisition by Westmin Resources Inc. in 1996. For over ten yeas prior to that, Mr. Myckatyn worked for various operations controlled by Placer Dome Inc. and its associated and predecessor companies including four separate mines in Australia and the Philippines. Mr. Myckatyn is the Lead Director of QuadraFNX Mining Ltd. and a director of First Point Minerals Corporation, San Marco Resources Inc. and OceanaGold Corporation. Mr. Myckatyn received his Bachelor of Applied Science in Mining Engineering from the University of British Columbia in 1972 and is a registered member of the British Columbia Association of Professional Engineers and Geoscientists.
     - 55 - The third member of the Companys audit committee, Anthony Petrina, is financially literate in that he has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Companys financial statements. Mr. Petrina worked for Placer Dome for 32 years, serving as President, Chief Executive Officer and Vice-Chairman, until his retirement in 1992. Mr. Petrina has been a director of several other mining companies since his retirement to date. Nomination of Directors The Nominating Committee is composed of two directors, Messrs. Petrina (Chair) and Myckatyn, each of whom are independent within the meaning of Section 803 of the NYSE Amex Company guide and based upon tests for independence set forth in NI 52-110. The Nominating Committee has the responsibility for recommending to the Board the nominees to fill vacancies on the Board or to be proposed by any member of the Board as candidates for election as directors at the annual general meeting. The Nominating Committee also recommends to the Board a desirable balance of expertise among the Board members, seeks out possible candidates to fill Board positions and aids in attracting qualified candidates to the Board. In addition, the Nominating Committees responsibilities include reviewing and monitoring the orientation of new Board members; reviewing and approving officers directorships in other companies and reviewing directors relationships with outside entities with regard to potential conflicts of interest. Compensation The Compensation Committee is composed of Messrs. Fagin (Chair), and Myckatyn, each of whom are independent within the meaning of Section 803 of the NYSE Amex Company guide and based upon tests for independence set forth in NI 52-110. The overall purpose of the Compensation Committee is to make recommendations to the Board for human resources and compensation policies and to implement and oversee same if the Board approves the recommendations for the Company. The Compensation Committee is responsible for reviewing all overall compensation strategy, objectives and policies; annually reviewing and assessing the performance of the executive officers; recommending to the Board the compensation of the executive officers; reviewing executive appointments; and reviewing the adequacy and form of directors compensation. To determine compensation payable, the Compensation Committee reviews compensation paid for directors and officers of companies of similar size and stage of development in the mineral exploration industry and determines an appropriate compensation reflecting the need to provide incentive and compensation for the time and effort expended by the directors and senior management while taking into account the financial and other resources of the Company. See also Statement of Executive Compensation above. No compensation consultant or advisor has, at any time since the beginning of the Companys most recently completed financial year, been retained to assist in determining compensation for any of the Companys directors and officers. Other Committees Committees of the Board are an integral part of the Companys governance structure. The Boards committees presently consist of an Audit Committee, a Compensation Committee, a Heath, Safety and Environmental Committee and a Nominating Committee. The Boards committees have been established to devote the necessary expertise and resources to particular areas, and to enhance the quality of discussion at Board meetings. The Committees facilitate effective Board decision making by providing recommendations to the Board on matters within their respective responsibilities. The Board believes that the Committees assist in the effective functioning of the Board and that the composition of the Committees should ensure that the views of the independent directors are effectively represented. A discussion of the Companys Audit, Nominating and Compensation Committees is provided above under the sub-headings Audit Committee, Nomination of Directors and Compensation. The Companys Health, Safety and Environmental Committee is composed of Messrs. Myckatyn (Chair), Shrake and Petrina, a majority of whom are considered independent based upon the tests for independence set forth in NI 52-110. The Health, Safety and Environmental Committee has the responsibility for reviewing the Companys environmental policy and for ensuring the Companys operations are operated in a manner consistent with the environmental policy and also for ensuring the Companys operations are run in a manner that does not unduly expose its employees to unnecessary risk of accident or death. The Board has determined that, at this stage of the Companys development, it is not necessary for the Board to have additional standing committees. The Board may from time to time appoint a special committee of one or more directors which committee may engage an outside advisor at the Companys expense in order to assist the committee in fulfilling its responsibilities.
     - 56 - Assessments The Board annually, and at such other times as it deems appropriate, reviews the performance and effectiveness of the Board, the directors and its committees to determine whether changes in size, personnel or responsibilities are warranted. To assist in its review, the Board conducts informal surveys of its Directors respecting its own effectiveness. In addition, the Board satisfies itself that the Board, its committees, and its individual directors are performing effectively through frequent discussions between management and individual Board members. There are also discussions among the independent directors with resulting comments to the Board. Shareholder Feedback and Concerns The Company is dedicated to the maintenance of good shareholder relations and attempts to deal with any expressed concerns of shareholders in an effective and timely manner. The Company employs a Vice-President of Investor Relations to monitor and promptly address shareholder concerns in an expeditious and informal manner. If any material issues of concern arise the Board of Directors is informed and provides direction for action as needed. The Company has a disclosure policy which is followed and is available for review on the Companys website. D.

     Memorandum and Articles of Association
  1.
     The Company, was formed on April 11, 2002 by the amalgamation of Dayton and Pacific Rim under the former Company Act (British Columbia). Now existing under the Business Corporations Act, S.B.C. 2002, c. 57 (British Columbia) (the Act), as amended, the Company, is permitted to conduct any lawful business that it s not restricted from conducting by its Notice of Articles and Articles, neither of which contain any restriction on the business the Company may conduct.2.
     A director who has a disclosable interest in a proposed contract or transaction with the Company shall be liable to account to the Company for any profits that accrue to the director under or as a result of the contract or transaction unless disclosure is made thereof and the contract or transaction is approved in accordance with the provisions of the Act. A director who holds a disclosable interest in a contract or transaction into which the Company has entered or proposes to enter into is not entitled to vote on any directors resolution to approve that contract or transaction, unless all the directors have a disclosable interest in that contract or transaction, in which case any or all of those directors may vote on such resolutions. The Articles of the Company permit an interested director to be counted in the quorum at the meeting whether or not the director votes on any or all of the resolutions considered at the meeting. The Company, if authorized by the board of directors, may borrow money, issue debt obligations and charge the assets of the Company, provided only that such power is exercised bona fide and in the best interests of the Company. There is no mandatory retirement age for directors. A director is not required to hold shares of the Company.3.
     The Company has only one class of common shares, without any special rights or restrictions. The dividend entitlement of a shareholder of record is fixed at the time of declaration by the board of directors. A vested dividend entitlement does not lapse, but unclaimed dividends are subject to a statutory six year contract debts limitation. Each common share is entitled to one vote on the election of each director. There are no cumulative voting rights, in consequence of which a simple majority of votes at the annual meeting can elect all the directors of the Company. Each common share carries with it the right to share equally with every other common share in dividends declared and in any distribution of surplus assets of the Company after payment to creditors on any winding up, liquidation or dissolution. There are no redemption or sinking fund provisions. All common shares must be fully paid prior to issue and are thereafter subject to no further capital calls by the Company. There exists no discriminatory provision affecting any existing or prospective holder of common shares as a result of such shareholder owning a substantial number of shares.
      - 59 - 4.
     Pursuant to the Act and the Articles of the Company, the rights of shareholders may be changed only by the shareholders passing a special resolution approved by two-thirds (2/3) of the votes cast at a general meeting of the Company, the notice of which is accompanied by a circular describing the proposed action and its effect on the shareholders. Certain special resolutions provide that a shareholder may dissent in respect of the resolution, by sending a notice of dissent to the Company and otherwise complying with the provisions of the Act. A shareholder who validly exercises such right of dissent in accordance with the Act may have the shares that are subject of the notice of dissent purchased by the Company at their fair value.5.
     The board of directors must call an annual general meeting once in each calendar year and not later than 15 months after the last such meeting. The board may call an extraordinary general meeting at any time. Notice of such meetings must be accompanied by information circular describing the proposed business to be dealt with and making the required disclosure regarding the Company and the matters to be considered at the meeting. A shareholder or shareholders holding in the aggregate of 5% of the issued shares of the Company may requisition a meeting and the board is required to hold such meeting within four months of such requisition. Admission to such meetings is open to registered shareholders and their duly appointed proxyholders. Others may be admitted with the consent of the meeting.6.
     The constating documents of the Company contain no limitations on the rights of non-resident or foreign shareholders to hold or exercise rights on the shares of the Company.7.
     There are no provisions in the Companys constating documents that would have an effect of delaying, deferring or preventing a change in control of the Company and that would operate only with respect to a merger, acquisition or corporate restructuring involving the Company or any of its subsidiaries.8.
     There are no provisions in the Companys constating documents that govern the ownership threshold above which shareholder ownership must be disclosed.9.
     There is no limitation at law upon the right of a non-resident to hold shares in a Canadian company. However, the Investment Canada Act (Canada) requires certain non-Canadian individuals, governments, corporations, agencies or entities who wish to acquire a Canadian business or to establish a new Canadian business as those terms are defined in that Act, to file a notification or an application for review with Investment Canada, a Canadian federal governmental agency. The Investment Canada Act requires that certain acquisitions of control of a Canadian business by a non-Canadian must be reviewed by the Minister responsible for the Act and approved on the basis that the Minister is satisfied that the acquisition is likely to be of net benefit to Canada, having regard to the criteria set forth in the Act. The Act makes the acquisition of  control a reviewable event. The Act sets out detailed rules for determining whether control has been acquired. The acquisition of one-third or more of the voting shares of a corporation may, in some circumstances, be deemed to constitute acquisition of control. A reviewable acquisition of control may not be implemented before being approved by the Minister. If not ultimately approved, a reviewable acquisition that has been completed may be subject to an order to divest, enforceable by injunction or a court order directing disposition of assets or shares.10.
     There are no provisions in the Companys constating documents that govern changes in capital that are more stringent that required by law. C.
     Material contracts
  On October 29, 2008 the Company announced that it had accepted an offer from its Denton-Rawhide joint venture partner, Kennecott Rawhide Mining Company (Kennecott), to purchase the net assets the Company holds through its 49% interest in the joint venture. Total compensation for these net assets included $3.1 million plus 49% of all gold and silver production from the Denton-Rawhide operation through to December 31, 2008 net of cash production costs. The Company was entitled to and received 49% of the gold and silver production from Denton-Rawhide (up to and including all gold and silver produced to December 31, 2008 only) as per the terms of sale described above. No further gold or silver production from Denton-Rawhide will be forthcoming to the Company. Readers are referred to the Companys news release of October 29, 2008 (available at www.pacrim-mining.com) for further information about the sale of the Denton-Rawhide assets.

     Exchange controls
  There are currently no governmental laws, decrees, regulations or other legislation of Canada which affect the import or export of capital, including the availability of cash and cash equivalents for use by the Company. E.
     Taxation
  Although not free from doubt, the Company believes it likely did not constitute a "passive foreign investment company" during the tax year ended April 30, 2010. However, the Company may constitute a passive foreign investment company in the current and future tax years. If the Company constitutes a passive foreign investment company for a tax year, such classification will likely have adverse U.S. federal income tax consequences for U.S. shareholders. Although the matter is not free from doubt, U.S. investors in our Common Shares should be aware that the Company believes that it likely did not constitute a passive foreign investment company (PFIC) during the tax year ended April 30, 2010. However, based on current business plans and financial projections, the Company believes there is a significant likelihood that it will be a PFIC for the current and future tax years. If the Company is a PFIC for any year during a U.S. shareholders holding period, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any so-called excess distribution received on its Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the shareholder makes a timely and effective "qualified electing fund" election (QEF Election) or a "mark-to-market" election with respect to the Common Shares. A U.S. shareholder who makes a QEF election generally must report on a current basis its share of the Company's net capital gain and ordinary earnings for any year in which the Company is a PFIC, whether or not the Company distributes any amounts to its shareholders. However, U.S. shareholders should be aware that there can be no assurance that we will satisfy record keeping requirements that apply to a qualified electing fund, or that we will supply U.S. shareholders with information that such U.S. shareholders require to report under the QEF rules, in the event that we are a PFIC and a U.S. shareholder wishes to make a QEF Election. Thus, U.S. shareholders may not be able to make a QEF Election with respect to their Common Shares. A U.S. shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayers basis therein. This paragraph is qualified in its entirety by the discussion below under the heading Certain United States Federal Income Tax Considerations. Each U.S. shareholder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our Common Shares. CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of Common Shares. This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and relating to the acquisition, ownership, and disposition of Common Shares. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including specific tax consequences to a U.S. Holder under an applicable tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of Common Shares. No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the IRS) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary. Scope of this Summary Authorities This summary is based on the Internal Revenue Code of 1986, as amended (the Code), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, U.S. court decisions, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the Canada-U.S. Tax Convention), and U.S. court decisions that are applicable and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive or prospective basis which could affect the U.S. federal income tax considerations described in this summary. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.
     - 61 - U.S. Holders For purposes of this summary, the term "U.S. Holder" means a beneficial owner of Common Shares that is for U.S. federal income tax purposes: an individual who is a citizen or resident of the U.S.;a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized under the laws of the U.S., any state thereof or the District of Columbia;an estate whose income is subject to U.S. federal income taxation regardless of its source; ora trust that (a) is subject to the primary supervision of a court within the U.S. and the control of one or more U.S. persons for  all substantial decisions or (b) has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. Non-U.S. Holders For purposes of this summary, a non-U.S. Holder is a beneficial owner of Common Shares that is not a U.S. Holder. This summary does not address the U.S. federal income tax consequences to non-U.S. Holders arising from and relating to the acquisition, ownership, and disposition of Common Shares. Accordingly, a non-U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences (including the potential application of and operation of any income tax treaties) relating to the acquisition, ownership, and disposition of Common Shares. U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including the following U.S. Holders: (a) U.S. Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) U.S. Holders that are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) U.S. Holders that are dealers in securities or currencies or U.S. Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) U.S. Holders that have a functional currency other than the U.S. dollar; (e) U.S. Holders that own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) U.S. Holders that acquired Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) U.S. Holders that hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) partnerships and other pass-through entities (and investors in such partnerships and entities); or (i) U.S. Holders that own or have owned (directly, indirectly, or by attribution) 10% or more of the total combined voting power of the outstanding shares of the Company. This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are (a) U.S. expatriates or former long-term residents of the U.S., (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Income Tax Act (Canada) (the Tax Act); (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Common Shares in connection with carrying on a business in Canada; (d) persons whose Common Shares constitute taxable Canadian property under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-U.S. Tax Convention. U.S. Holders that are subject to special provisions under the Code, including U.S. Holders described immediately above, should consult their own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of Common Shares. If an entity that is classified as a partnership (or pass-through entity) for U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax consequences to such partnership and the partners of such partnership generally will depend on the activities of the partnership and the status of such partners. Partners of entities that are classified as partnerships for U.S. federal income tax purposes should consult their own tax advisor regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Common Shares. Tax Consequences Not Addressed This summary does not address the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Common Shares. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.
     - 62 - Passive Foreign Investment Company Rules If the Company were to constitute a passive foreign investment company under the meaning of Section 1297 of the Code (a PFIC, as defined below) for any year during a U.S. Holders holding period, then certain different and potentially adverse rules will effect the U.S. federal income tax consequences to a U.S. Holder resulting from the acquisition, ownership and disposition of Common Shares. In addition, in any year in which the Company is classified as a PFIC, such holder would be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidelines may require. PFIC Status of the Company The Company generally will be a PFIC if, for a tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income (the income test) or (b) 50% or more of the value of the Companys assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the asset test). Gross income generally means all sales revenues less the cost of goods sold, and passive income generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporations commodities are (a) stock in trade of such foreign corporation or other property of a kind which would properly be included in inventory of such foreign corporation, or property held by such foreign corporation primarily for sale to customers in the ordinary course of business, (b) property used in the trade or business of such foreign corporation that would be subject to the allowance for depreciation under Section 167 of the Code, or (c) supplies of a type regularly used or consumed by such foreign corporation in the ordinary course of its trade or business. For purposes of the PFIC income test and asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the Company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, passive income does not include any interest, dividends, rents, or royalties that are received or accrued by the Company from a related person (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income. In addition, under certain attribution rules, if the Company is a PFIC, U.S. Holders will be deemed to own their proportionate share of any subsidiary of the Company which is also a PFIC (a Subsidiary PFIC), and will be subject to U.S. federal income tax on their proportionate share of (a) a distribution on the shares of a Subsidiary PFIC and (b) a disposition or deemed disposition of shares of a Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC. Although the matter is not free from doubt because the Company disposed of its interest in the Denton-Rawhide joint venture, the Company believes that it likely did not constitute a PFIC during the tax year ended April 30, 2010. Based on current business plans and financial expectations, the Company believes that there is a significant likelihood that it will be a PFIC for current and future tax years. The determination of whether any corporation was, or will be, a PFIC for a tax year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any tax year depends on the assets and income of such corporation over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Company (or a Subsidiary PFIC) concerning its PFIC status or that the Company (and each Subsidiary PFIC) was not, or will not be, a PFIC for any tax year. Each U.S. Holder should consult its own tax advisor regarding the PFIC status of the Company and each Subsidiary PFIC. Default PFIC Rules Under Section 1291 of the Code If the Company is a PFIC, the U.S. federal income tax consequences to a U.S. Holder of the acquisition, ownership, and disposition of Common Shares will depend on whether such U.S. Holder makes an election to treat the Company and any Subsidiary PFICs as a qualified electing fund or QEF under Section 1295 of the Code (a QEF Election) or a mark-to-market election under Section 1296 of the Code (a Mark-to-Market Election). A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a Non-Electing U.S. Holder. A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of Common Shares and (b) any excess distribution received on the Common Shares. A distribution generally will be an excess distribution to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a U.S. Holders holding period for the Common Shares, if shorter).
     - 63 - Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares, and any excess distribution received on Common Shares, must be ratably allocated to each day in a Non-Electing U.S. Holders holding period for the respective Common Shares. The amount of any such gain or excess distribution allocated to the tax year of disposition or distribution of the excess distribution and to years before the entity became a PFIC, if any, would be taxed as ordinary income. The amounts allocated to any other tax year would be subject to U.S. federal income tax at the highest tax applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as personal interest, which is not deductible. If the Company is a PFIC for any tax year during which a Non-Electing U.S. Holder holds Common Shares, the Company will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent tax years. A Non-Electing U.S. Holder may terminate this deemed PFIC status by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Common Shares were sold on the last day of the last tax year for which the Company was a PFIC. QEF Election A U.S. Holder that makes a QEF Election for the first tax year in which its holding period of its Common Shares begins, generally, will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Common Shares. However, a U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such U.S. Holders pro rata share of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such U.S. Holder, and (b) the ordinary earnings of the Company, which will be taxed as ordinary income to such U.S. Holder. Generally, net capital gain is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and ordinary earnings are the excess of (a) earnings and profits over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each tax year in which the Company is a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by the Company. However, for any tax year in which the Company is a PFIC and has no net income or gain, U.S. Holders that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a U.S. Holder that made a QEF Election has an income inclusion, such a U.S. Holder may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as personal interest, which is not deductible. A U.S. Holder that makes a QEF Election generally (a) may receive a tax-free distribution from the Company to the extent that such distribution represents earnings and profits of the Company that were previously included in income by the U.S. Holder because of such QEF Election and (b) will adjust such U.S. Holders tax basis in the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a U.S. Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Common Shares. The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as timely if such QEF Election is made for the first year in the U.S. Holders holding period for the Common Shares in which the Company was a PFIC. A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such year. A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent tax year, the Company ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which the Company is not a PFIC. Accordingly, if the Company becomes a PFIC in another subsequent tax year, the QEF Election will be effective and the U.S. Holder will be subject to the QEF rules described above during any subsequent tax year in which the Company qualifies as a PFIC. U.S. Holders should be aware that there can be no assurances that the Company will satisfy the record keeping requirements that apply to a QEF, or that the Company will supply U.S. Holders with information that such U.S. Holders require to report under the QEF rules, in the event that the Company is a PFIC and a U.S. Holder wishes to make a QEF Election. Thus, U.S. Holders may not be able to make a QEF Election with respect to their Common Shares. Each U.S. Holder should consult its own tax advisor regarding the availability of, and procedure for making, a QEF Election. Mark-to-Market Election A U.S. Holder may make a Mark-to-Market Election only if the Common Shares are marketable stock. The Common Shares generally will be marketable stock if the Common Shares are regularly traded on (a) a national securities exchange that is registered with the Securities and Exchange Commission, (b) the national market system established pursuant to section 11A of the Securities and Exchange Act of 1934, or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange ensure active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be regularly traded for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter.
     - 64 - A U.S. Holder that makes a Mark-to-Market Election with respect to its Common Shares generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to such Common Shares. However, if a U.S. Holder does not make a Mark-to-Market Election beginning in the first tax year of such U.S. Holders holding period for the Common Shares or such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares. A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which the Company is a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common Shares, as of the close of such tax year over (b) such U.S. Holders tax basis in such Common Shares. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (a) such U.S. Holders adjusted tax basis in the Common Shares, over (b) the fair market value of such Common Shares (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years). A U.S. Holder that makes a Mark-to-Market Election generally also will adjust such U.S. Holders tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of Common Shares, a U.S. Holder that makes a Mark-to-Market Election will recognize ordinary income or ordinary loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years). A Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the Common Shares cease to be marketable stock or the IRS consents to revocation of such election. Each U.S. Holder should consult its own tax advisor regarding the availability of, and procedure for making, a Mark-to-Market Election. Although a U.S. Holder may be eligible to make a Mark-to-Market Election with respect to the Common Shares, no such election may be made with respect to the stock of any Subsidiary PFIC that a U.S. Holder is treated as owning, because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge described above with respect to deemed dispositions of Subsidiary PFIC stock or distributions from a Subsidiary PFIC. Other PFIC Rules Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a U.S. Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Common Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations). However, the specific U.S. federal income tax consequences to a U.S. Holder may vary based on the manner in which Common Shares are transferred. Certain additional adverse rules will apply with respect to a U.S. Holder if the Company is a PFIC, regardless of whether such U.S. Holder makes a QEF Election. For example under Section 1298(b)(6) of the Code, a U.S. Holder that uses Common Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Common Shares. Special rules also apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC. Subject to such special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. The rules relating to distributions by a PFIC and their eligibility for the foreign tax credit are complicated, and a U.S. Holder should consult with their own tax advisor regarding the availability of the foreign tax credit with respect to distributions by a PFIC. The PFIC rules are complex, and each U.S. Holder should consult its own tax advisor regarding the PFIC rules and how the PFIC rules may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares. U.S. Federal Income Tax Consequences of the Acquisition, Ownership, and Disposition of Common Shares The following discussion is subject to the rules described above under the heading Passive Foreign Investment Company Rules. Distributions on Common Shares
     - 65 - Subject to the PFIC rules discussed above, a U.S. Holder that receives a distribution, including a constructive distribution, with respect to a Common Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated earnings and profits of the Company, as computed for U.S. federal income tax purposes. A dividend generally will be taxed to a U.S. Holder at ordinary income tax rates. To the extent that a distribution exceeds the current and accumulated earnings and profits of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder's tax basis in the Common Shares and thereafter as gain from the sale or exchange of such Common Shares. (See  Sale or Other Taxable Disposition of Common Shares below). However, the Company may not maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder should therefore assume that any distribution by the Company with respect to the Common Shares will constitute ordinary dividend income. Dividends received on Common Shares generally will not be eligible for the dividends received deduction. In addition, the Company does not anticipate that its distributions will be eligible for the preferential tax rates applicable to long-term capital gains. The dividend rules are complex, and each U.S. Holder should consult its own tax advisor regarding the application of such rules. Sale or Other Taxable Disposition of Common Shares Subject to the PFIC rules discussed above, upon the sale or other taxable disposition of Common Shares, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash plus the fair market value of any property received and such U.S. Holder's tax basis in such Common Shares sold or otherwise disposed of. Subject to the PFIC rules discussed above, gain or loss recognized on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the Common Shares have been held for more than one year. Gain or loss recognized by a U.S. Holder on the sale or other taxable disposition of Common Shares generally will be treated as U.S. source for purposes of applying the U.S. foreign tax credit rules unless the gain is subject to tax in Canada and is resourced as foreign source under the Canada-U.S. Tax Convention and such U.S. Holder elects to treat such gain or loss as foreign source. Preferential tax rates apply to long-term capital gain of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gain of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code. Recent Legislative Developments Newly enacted legislation requires certain U.S. Holders who are individuals, estates or trusts to pay up to an additional 3.8% tax on, among other things, dividends and capital gains for tax years beginning after December 31, 2012. In addition, for tax years beginning after March 18, 2010, new legislation requires certain U.S. Holders who are individuals that hold certain foreign financial assets (which may include the Common Shares) to report information relating to such assets, subject to certain exceptions. U.S. Holders should consult their tax advisors regarding the effect, if any, of this legislation on their ownership and disposition of Common Shares. Additional Considerations Receipt of Foreign Currency The amount of any distribution paid to a U.S. Holder in foreign currency, or on the sale, exchange or other taxable disposition of Common Shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency. Foreign Tax Credit Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Common Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. Holders U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holders income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. Holders U.S. federal income tax liability that such U.S. Holders foreign source taxable income bears to such U.S. Holders worldwide taxable income. In applying this limitation, a U.S. Holders various items of income and deduction must be classified, under complex rules, as either foreign source or U.S. source. Generally, dividends paid by a foreign corporation should be treated as foreign source for this purpose, and gains recognized on the sale of stock of a foreign corporation by a U.S. Holder should be treated as U.S. source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to the Common Shares that is treated as a dividend may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition, this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and each U.S. Holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.
     - 66 - Backup Withholding and Information Reporting Under U.S. federal income tax law and Treasury regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, recently enacted legislation generally imposes new U.S. return disclosure obligations (and related penalties) on U.S. Holders that hold certain specified foreign financial assets in excess of $50,000. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U.S. Holders may be subject to these reporting requirements unless their Common Shares are held in an account at a domestic financial institution. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult with their own tax advisors regarding the requirements of filing information returns, and, if applicable, filing obligations relating to a Mark-to-Market or QEF Election. Payments made within the U.S. or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Common Shares generally may be subject to information reporting and backup withholding tax, at the rate of 28% (and increasing to 31% for payments made after December 31, 2010), if a U.S. Holder (a) fails to furnish such U.S. Holders correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons, such as corporations, generally are excluded from these information reporting and backup withholding rules. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holders U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner. Each U.S. Holder should consult its own tax advisor regarding the information reporting and backup withholding rules. F.

     - 67 - ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK A.
     Quantitative Disclosure about Market Risk
  The Company holds its cash and cash equivalents primarily in U.S. dollar and Canadian dollar denominated accounts and its expenses are primarily incurred in U.S. dollars. At April 30, 2010 the amount of cash and cash equivalents held was $1,333, the amount of accounts receivable was $81 and the amount of accounts payable and accrued liabilities was $2,626. Based on these net exposures at April 30, 2010 and assuming that all other variables remain constant, a 10% depreciation or appreciation of the US dollar against the Canadian dollar would result in an increase or decrease of $76 in the Companys net earnings. The Company is subject to price risk from fluctuations in the market price of gold and silver as a result of it holding bullion, which in turn is affected by numerous factors including central bank policies, producer hedging activities, the value of the US dollar relative to other major currencies, global demand and supply and global political and economic conditions. The following table summarizes the remaining contractual maturities of the Companys financial liabilities and operating and capital commitments at April 30, 2010: 2011$

     Qualitative Disclosure about Market Risk
  The Companys objectives when managing capital and risk are: To maintain adequate capital to operate its business and safeguard its ability to continue as a going concern; andTo minimize the use of debt prior to the commencement of development activities The Company continuously assesses its capital structure in light of economic conditions, debt and equity markets and changes in the Companys short-term and long-term plans. The Company is not subject to externally imposed capital requirements. Credit Risk Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. The Companys credit risk is primarily attributable to its liquid financial assets. The Company limits its exposure to credit risk by depositing its cash and cash equivalents with international financial institutions. The Company does not have financial assets that are invested in asset based commercial paper. Commodity Price Risk Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. The Companys credit risk is primarily attributable to its liquid financial assets and the maximum credit risk the Company is exposed to is 100% of cash and receivables. The Company limits its exposure to credit risk by depositing its cash and cash equivalents with international financial institutions. The Company does not have financial assets that are invested in asset based commercial paper. Foreign Currency Risk Foreign exchange risk is the risk that the fair value of the Companys financial instruments will fluctuate because of changes in foreign exchange rates. The Company holds its cash and cash equivalents primarily in U.S. dollar and Canadian dollar denominated accounts and its expenses are primarily incurred in U.S. dollars. At April 30, 2010 the amount of cash and cash equivalents held was $1,333, the amount of accounts receivable was $81 and the amount of accounts payable and accrued liabilities was $2,626. Based on these net exposures at April 30, 2010 and assuming that all other variables remain constant, a 10% depreciation or appreciation of the U.S. dollar against the Canadian dollar would result in an increase or decrease of $76 in the Companys net earnings. The Company has not entered into any derivative contracts to manage foreign exchange risk at this time.
     - 68 - U.S. dollar against the Canadian dollar would result in an increase or decrease of $76 in the Companys net earnings. The Company has not entered into any derivative contracts to manage foreign exchange risk at this time. Liquidity Risk Liquidity risk is the risk that the Company will encounter difficulty in raising funds to meet its operating commitments. The Company does not presently have sufficient working capital to meet its accounts payable and accrued liabilities, nor its anticipated exploration and general and administrative expenses or the estimated costs of pursuing the CAFTA action during fiscal 2011. The Company will require financing during fiscal 2011 to meet these expenses and obligations. The Company seeks to manage liquidity by maintaining adequate cash and cash equivalent balances to meet its short term commitments and by raising equity or debt financing as required to meet long term commitments The Company has no assurance that such financing will be available or be available on favorable terms. Factors that could affect the availability of financing include Pacific Rims performance as measured by various factors including the progress and permitting of the El Dorado project, the state of international debt and equity markets, investor perceptions and expectations and the global financial and metals markets. Fair Values As at April 30, 2010, the Companys carrying values of receivables, deposits and accounts payable and accrued liabilities approximate fair values due to their short terms to maturity.

  Not Applicable ITEM 15. CONTROLS AND PROCEDURES A.
     Disclosure controls and procedures
  Management has designed disclosure controls and procedures, or has caused them to be designed under its supervision, to provide reasonable assurance that material information related to the Company is gathered and reported to senior management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), as appropriate to permit timely decisions regarding public disclosure. The Company has not changed its disclosure controls during the twelve months ended April 30, 2010 that has materially affected, or is reasonably likely to materially affect, its control over disclosures. Due to staffing changes made during the year ended April 30, 2009, the Chief Financial Officer became responsible for preparing, authorizing, and reviewing information that is key to the preparation of financial reports. He is also responsible for preparing and reviewing the resulting financial reports. This weakness has the potential to result in material misstatements in the Companys financial statements, and should be considered a material weakness in its disclosure controls and procedures. B.
     Managements annual report on internal control over financial reporting
  Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended (Exchange Act). Management has designed internal control over financial reporting, or caused it to be designed under its supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements. Any system of internal control over financial reporting, regardless of how well designed, has inherent limitations. As such, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. There has been no change to the Companys internal controls over financial reporting during the twelve months ended April 30, 2010 that has materially affected, or is reasonably likely to materially affect, its control over financing reporting. A material weakness is a control deficiency, or combination of control deficiencies, such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. The Companys CEO and CFO assessed the design and operating effectiveness of the Companys internal control over financial reporting as at April 30, 2010: Based on that assessment, management concluded that, as at April 30, 2010, the Companys internal control over financial reporting was not effective due to the existence of a material weakness in the design of internal control over financial reporting caused by a lack of adequate segregation of duties in the financial close process. The Chief Financial Officer is responsible for preparing, authorizing, and reviewing information that is integral to the preparation of financial reports. He is also responsible for preparing and reviewing the resulting financial reports. The weakness has the potential to result in material misstatements in the Companys financial statements, and should also be considered a material weakness in its disclosure controls and procedures. Management has concluded that taking into account the present stage of the Companys development the Company does not have sufficient size and scale to warrant hiring of additional staff to correct the weakness at this time.
     - 70 - This annual report on Form 20-F does not include an attestation report of the Companys registered public accounting firm regarding internal control over financial reporting. Managements report was not subject to attestation by the Companys registered public accounting firm pursuant to temporary rules of the SEC that permit the Company to provide only Managements report in this annual report. C.
     Changes in internal control over financial reporting
  During the period covered by this annual report on Form 20-F, there has been no change to the Companys internal controls over financial reporting that has materially affected, or is reasonably likely to materially affect, its control over financing reporting. The Chief Financial Officer is responsible for preparing, authorizing, and reviewing information that is key to the preparation of financial reports. He is also responsible for preparing and reviewing the resulting financial reports, which represents a weakness that has the potential to result in material misstatements in the Companys financial statements. Management has concluded that taking into account the present stage of the Companys development the Company does not have sufficient size and scale to warrant hiring of additional staff to correct the weakness at this time. ITEM 16 [RESERVED] ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT David Fagin is a financial expert, in that he has an understanding of generally accepted accounting principles and financial statements; is able to assess the general application of accounting principles in connection with the accounting for estimates, accruals and reserves; has experience preparing, auditing, analyzing or evaluating financial statements that entail accounting issues of equal complexity to the Companys financial statements (or actively supervising another person who did so); has an understanding of internal controls and procedures for financial reporting and an understanding of audit committee functions. Mr. Fagin does not have an accounting designation; instead his expertise is derived from his high level involvement in the financial matters of public corporations almost continuously for at least 35 years. Mr. Fagin was involved in the valuation of oil and gas companies for ten years both as a consultant and a bank appraisal engineer (1958-68); President of a subsidiary of Rosario Resources Corporation, a NYSE company (1968-75) and then Executive Vice-President (1975-77) then President (1977-82) during which period he was intimately involved in financial and accounting matters. In 1982, he founded Fagin Exploration Company and worked closely with an accountant and auditors to maintain the records. From 1986 to 1991, Mr. Fagin was the President and Chief Operating Officer for Homestake Mining Corporation (NYSE), responsible for producing operations in six countries and was involved in decisions for corporate financial reporting.

ITEM 16B. CODE OF ETHICS The Company has had in place, since 2002, a Code of Conduct and Ethics (the Code). A revised Code was approved by the Board of Directors of the Company on December 17, 2002. A copy of the Code can be found on the Companys website at http://www.pacrim-mining.com/s/CorporateGovernance.asp. There have never been any departures or material waivers of the Code since its inception. ITEM 16C.

     The aggregate fees billed for products and services other than as set out under the heading Audit Fees, Audit Related Fees and Tax Fees. Audit Fees are the aggregate fees billed by PricewaterhouseCoopers LLP for the audit of the Companys consolidated annual financial statements and attestation services that are provided in connection with statutory and regulatory filings or engagements. Audit-Related Fees are the fees billed by PricewaterhouseCoopers LLP for assurance and related services that are reasonably related to the performance of the audit or review of the Companys financial statements and are not reported under Audit Fees. This category comprises fees billed for independent accountant review of the interim financial statements and Management Discussion and Analysis, as well as advisory services associated with the Companys financial reporting. Tax Fees are the fees billed for professional services rendered by PricewaterhouseCoopers LLP for tax compliance, tax advice, and tax planning. Pre-Approval Policies and Procedures The Audit Committee nominates and engages the independent auditors to audit the financial statements, and approves all audit, audit-related services, tax services and other services provided by independent auditors. Any services provided by the independent auditors that are not specifically included within the scope of the audit must be pre-approved by the Audit Committee prior to any engagement. The Audit Committee is permitted to approve certain fees for audit-related services, tax services and other services pursuant to a de minimusexception before the completion of the engagement. ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES None. ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS None. ITEM 16F. CHANGE IN REGISTRANTS CERTIFYING ACCOUNTANT None. ITEM 16G. CORPORATE GOVERNANCE The Companys common shares are listed on the NYSE Amex. Section 110 of the Amex Company Guide permits the NYSE Amex to consider the laws, customs and practices of foreign issuers in relaxing certain NYSE Amex listing criteria, and to grant exemptions from NYSE Amex listing criteria based on these considerations. A company seeking relief under these provisions is required to provide written certification from independent local counsel that the non-complying practice is not prohibited by home country law. A description of the significant ways in which the Companys governance practices differ from those followed by domestic companies pursuant to NYSE Amex standards is as follows: Shareholder Meeting Quorum Requirement: The NYSE Amex minimum quorum requirement for a shareholder meeting is one-third of the outstanding shares of common stock. In addition, a company listed on the NYSE Amex is required to state its quorum requirement in its bylaws. The Companys quorum requirement is set forth in its Memorandum and Articles. A quorum for a meeting of members of the Company is two persons who are, or who represent by proxy, shareholders who, in the aggregate, hold at least 5% of the shares entitled to be voted at the meeting.
     - 72 - Proxy Delivery Requirement:The NYSE Amex requires the solicitation of proxies and delivery of proxy statements for all shareholder meetings, and requires that these proxies shall be solicited pursuant to a proxy statement that conforms to SEC proxy rules. The Company is a foreign private issuer as defined in Rule 3b-4 under the Exchange Act, and the equity securities of the Company are accordingly exempt from the proxy rules set forth in Sections 14(a), 14(b), 14(c) and 14(f) of the Exchange Act. The Company solicits proxies in accordance with applicable rules and regulations in Canada. The foregoing are consistent with the laws, customs and practices in Canada. In addition, we may from time-to-time seek relief from the NYSE Amex corporate governance requirements on specific transactions under Section 110 of the NYSE Amex Company Guide by providing written certification from independent local counsel that the non-complying practice is not prohibited by our home country law, in which case, we shall make the disclosure of such transactions available on our website at www.pacrim-mining.com. Information contained on our website is not part of this annual report.
