Accordingly, this Amendment No. 1 on Form 10-K/A should be read in conjunction with our filings made with the Securities and Exchange Commission subsequent to the filing of the Original Filing, including any amendments to those filings.    PART I  ITEM 1. BUSINESS  Background  Mexoro Minerals Ltd. (formerly known as Sunburst Acquisitions IV, Inc.) (the Company, or Mexoro) was incorporated in the State of Colorado on August 27, 1997. We were formed to seek out and acquire business opportunities. Between 1997 and 2003, we engaged in two business acquisitions and one business opportunity, none of which generated a significant profit or created a sustainable business for us.  On May 3, 2004, we completed a Share Exchange Agreement with Sierra Minerals and Mining, Inc. (Sierra Minerals), a Nevada corporation, which caused Sierra Minerals to become our wholly owned subsidiary. At the time of the share exchange transaction, Sierra Minerals held, through a joint venture with Minera Rio Tinto, S.A. de C.V. (MRT), a company duly incorporated pursuant to the laws of the United Mexican States, mineral concessions and options to obtain certain mineral concessions on properties in Chihuahua, Mexico. Because Sierra Minerals was not a Mexican company, it was prohibited by Mexican law from owning the mineral concessions directly. The joint venture allowed Sierra Minerals to have rights to these concessions while maintaining compliance with Mexican law. MRT was controlled, and continues to be controlled, by Mario Ayub. Concurrently with the Share Exchange Agreement, Mr. Ayub became a director, and later Chief Operating Officer, of Mexoro. In August 2005, Mexoro cancelled the joint venture agreement in order to pursue the mineral exploration opportunity through a new wholly owned Mexican subsidiary. On January 20, 2006, Sierra Minerals was dissolved.  In August 2005, we created a wholly owned Mexican subsidiary corporation, Sunburst de Mexico, S.A. de C.V. (Sunburst de Mexico). On August 25, 2005, Sunburst de Mexico, Mexoro and MRT entered into agreements in which MRT assigned to Sunburst de Mexico the right to explore and exploit two properties in Mexico. MRT had previously acquired property rights from the owners, Corporativo Minero, S.A. de C.V. (Corporativo Minero), and Compañía Minera De Namiquipa, S. A. de C. V. (Compañía Minera), respectively. There is no relationship between either Corporativo Minero or Compañía Minera, their officers, directors and affiliates and Mexoros subsidiaries, officers, directors and affiliates. Concurrent with assigning to  2   Sunburst de Mexico its rights to these two properties, MRT assigned to Sunburst de Mexico the option, but not the obligation, to purchase additional mineral concessions on a separate property, also located in Chihuahua, Mexico.  Through Sunburst de Mexico, we are engaged in the exploration of four gold and silver exploration properties, each made up of several mining concessions, located in the State of Chihuahua, Mexico. (Mining Concessions refers to an area of land for which the owner of the concession has the right to explore for and develop mineral deposits. The rights to and ownership of the minerals in the concessions were granted, in our case, originally by the Mexican Government to the former concession owners, and then to us from those owners. In Canada and the United States, the term is commonly referred to as Mineral Rights or Mining Claims.)  These properties are generally referred to as the Cieneguita Property, the Guazapares Property, the Encino Gordo Property and the Sahauyacan Property. We will own 100% of the Cieneguita Property upon completion of a payment of $2,000,000 to Corporativo Minero and we have the option to purchase the Guazapares Property. In August 2005, we purchased two Encino Gordo mineral concessions for $100, and we have exercised our option to purchase three additional Encino Gordo mineral concessions from an unrelated third party, all of which now comprise the Encino Gordo Property.  In December 2005, Mexoro and Sunburst de Mexico entered into a new agreement with MRT (the New Agreement). In the New Agreement, Sunburst de Mexico exercised its option to purchase three additional mining concessions in the Encino Gordo region. The New Agreement required the Company to issue to MRT two million shares of Mexoros common stock within four months of the date of the signing of the New Agreement. These shares were issued on February 23, 2006. Under the terms of the New Agreement, MRT had the option to buy all of the outstanding shares of Sunburst de Mexico for $100 if the Company failed to transfer $1,500,000 to Sunburst de Mexico by April 30, 2006. However, in April 2006, the parties amended the New Agreement to delete both the required transfer of $1,500,000 to Sunburst de Mexico along with MRTs option to purchase all of the shares of Sunburst de Mexico. The New Agreement also requires the Company to issue one million additional shares of common stock to MRT when, if ever, production of the Cieneguita Property reaches 85% of production capacity.  On October 24, 2006, we purchased exclusive exploration rights and an option to purchase several additional mineral concessions, collectively referred to as the Sahauyacan Property, in Chihuahua, Mexico, from Minera Emilio, S.A. de C.V.,(Minera Emilio). There is no relationship between Minera Emilio, its officers, directors and affiliates and Mexoros subsidiaries, officers, directors and affiliates. In order to maintain the right to explore the Sahauyacan Property, the Company paid $30,000 upon execution of the agreement and must pay $252,000 in monthly installments over a five year term. In order to purchase the Sahauyacan Property, Mexoro must pay $300,000 in cash or $500,000 in shares of the Company within the term of the option. The Company must also pay a royalty of 3% or 4% of Net Revenues. Net Revenue is calculated by subtracting smelting expenses, added value taxes and all other taxes on production sales from revenue described in detail below.  On February 13, 2006, the shareholders of the Company approved a 1:50 reverse split of its issued and outstanding common stock with one new share issued for each 50 old shares. Prior to the reverse split, the Company had 189,994,324 shares of common stock issued and outstanding. Immediately following the reverse split, the Company had 3,799,887 shares issued and outstanding. All figures relating to shares of common stock or price of shares of common stock herein reflect the 1:50 reverse split unless otherwise indicated.  We changed our name to Mexoro Minerals Ltd. on February 15, 2006. As of the date of this report, we are considered to be an exploration stage corporation, as that term is defined in the U.S. Securities and Exchange Commissions (SEC) Industry Guide 7, as we are engaged in the search for mineral deposits but not engaged in the preparation of an established commercially mineable deposit for extraction or in the exploitation of a mineral deposit.  Prior Acquisitions  In August 1999, we invested $1,000,000 in Prologic Management Systems, Inc. (Prologic), which was engaged in the business of providing systems integration services, networking services, software development and applications software for the commercial market. The investment in Prologic was made in anticipation of a business combination with that company. As part of that transaction, we acquired 3,459,972 shares of Prologic. However, the agreement to complete a business combination was terminated prior to its consummation and in March 2000 we charged off our investment to operations.  In January 2001, we entered into an agreement with Prologic to recover a portion of our investment. Pursuant to that agreement, on February 16, 2001, we completed the sale of 2,859,972 shares of stock in Prologic to Prologic, or its  3   designees, for a total sales price of $400,000. Of the sale price, $325,000 was paid in cash at closing and $75,000 through Prologics execution of a promissory note. The promissory note bore interest at the rate of 10% per annum and required payments of $25,000 principal, plus accrued interest, on each of April 12, 2001, July 12, 2001 and October 12, 2001, none of which were ever received by us. Subsequently, Prologic declared bankruptcy and we wrote the promissory note off as uncollectible.  We retained ownership of a total of 600,000 shares of Prologic, which we subsequently sold. Such shares were restricted securities as defined in Rule 144 under the Securities Act of 1933. The shares were sold in accordance with the provisions of Rule 144.   On December 4, 2000, the Company completed an agreement for share exchange between itself and HollywoodBroadcasting.com, Inc. (HBC), a Nevada corporation. As a result of that closing, HBC became a wholly-owned subsidiary of the Company.  HBC was a development stage company formed for the purpose of developing and producing original entertainment and information programming for various media including domestic and foreign broadcast, cable and satellite television, home video, DVD sales and rentals and the Internet. The Company was not able to generate significant revenues from any of the sources it relied upon in establishing its business model.  On September 28, 2001, the Company completed the sale of its wholly-owned subsidiary HBC for $1,000 in cash.  Prior Business Activities  On February 27, 2002, we were assigned a sub-distributorship agreement pursuant to a contract between 1357784 Ontario Ltd. and Romlight International, Inc. (Romlight International), a company based in Toronto, Ontario, Canada. There was no affiliation between 1357784 Ontario Ltd. and Romlight International and Prologic, HBC, Sierra Minerals, Mexoro, their officers, directors or affiliates. Pursuant to the sub-distributorship agreement, we became the exclusive worldwide distributor to the hydroponics industry of digital electronic lighting ballasts. This sub-distributorship agreement was assigned to our wholly owned subsidiary, Sunburst Digital, Inc. (Sunburst Digital), a Canadian corporation. In January 2003, the contract between 1357784 Ontario Ltd. and Romlight International and our sub-distributorship agreement were cancelled. On April 2, 2003, Sunburst Digital signed an agreement directly with Romlight International containing terms and conditions substantially identical to the terms of the sub-distributorship agreement.  We paid Romlight International a deposit of $183,454 for the sub-distributorship. Due to quality control issues, the ballasts were never sold, and we wrote off our entire deposit and ceased to operate Sunburst Digital. Sunburst Digital was administratively dissolved on March 31, 2006. We had no operations between the cessation of these activities and the acquisition of Sierra Minerals.  Current Operations  On May 3, 2004, we entered into a Share Exchange Agreement with the shareholders of Sierra Minerals, which was incorporated in Nevada on March 19, 2004. As a result of this transaction, Sierra Minerals became our wholly owned subsidiary. Pursuant to the Share Exchange Agreement, we agreed to loan to MRT, on behalf of Sierra Minerals, $147,500 to be evidenced by an 8% promissory note signed by MRT. In addition, and as a result of the closing of this Share Exchange Agreement, we paid a finders fee to two corporate entities whereby we issued an aggregate of 120,000 five year options to purchase shares of our common stock, at a price of $0.50 per share, as follows: 60,000 were issued to T.R. Winston & Company, LLC and 60,000 were issued to Liberty Management, LLC. T.R. Winston & Company, LLC, Liberty Management, LLC, and their officers, directors and affiliates are not affiliates of Mexoro, Sierra Minerals, MRT or their officers, directors, and affiliates.  Sierra Minerals had no operations between its date of incorporation and April 26, 2005. Sierra Minerals was a party to a joint venture agreement dated April 26, 2004 and amended on June 1, 2004, by and between Sierra Minerals and MRT. MRT had the right to acquire certain mineral concessions, the Cieneguita Property and Guazapares Property, as explained below. Under the terms of the joint venture, MRT and Sierra Minerals planned to form a Mexican corporation, of which Sierra Minerals would own 60% and MRT would own 40%. Sierra Minerals was required to invest $1,000,000 in this corporation within 30 days of the signing of the joint venture agreement and to secure an additional $2,000,000 line of credit for the new company. In exchange, MRT would transfer its rights in the mineral concessions to the new corporation. MRT was appointed  4   as the operator of the Cieneguita Property. Sierra Minerals advanced $167,500 to MRT, pursuant to the joint venture agreement, to pay for costs associated with the rights. However, Sierra Minerals did not meet the deadline of investing $1,000,000 into the new corporation. MRT retained the $167,500 as liquidated damages under the joint venture agreement; Sierra Minerals was not required to pay any additional damages.  The board of directors decided that it wanted to hold these mineral concessions and options for mineral concessions directly instead of through a joint venture agreement due to its belief that holding the title directly is a stronger legal position for the Company. Consequently, the joint venture agreement was cancelled and a new subsidiary formed. Once the joint venture agreement was cancelled, Sierra Minerals no longer had any rights to the mineral concessions.  On August 25, 2005, we entered into a new arrangement with MRT. Instead of a joint venture, we formed a wholly owned subsidiary, Sunburst de Mexico, which was incorporated in Mexico. Because Sunburst de Mexico is a Mexican corporation, this restructuring allowed us to take title to the properties directly in the name of Sunburst de Mexico rather than holding the interests in a joint venture. We entered into agreements with MRT, which gave Sunburst de Mexico options to purchase the mineral concessions of the Cieneguita and Guazapares Properties and the right of first refusal on two Encino Gordo Properties. The parties also entered into an operating agreement (which has subsequently been cancelled) that gave MRT the sole and exclusive right and authority to manage the Cieneguita Property. (This right had also been granted to MRT under the joint venture agreement with Sierra Minerals.)  The material provisions of the Companys property agreements are as follows:  (1)MRT assigned to Sunburst de Mexico, with the permission of Corporativo Minero (the Cieneguita Owner), all of MRTs rights and obligations acquired under a previous agreement, the Cieneguita Option Agreement, including the exclusive option to acquire the Cieneguita concessions for a price of $2,000,000. The Cieneguita Option Agreement states that the Company is to make yearly payments on May 6 of each year in the amount of $120,000 for the next 13 years and a final payment of the outstanding balance owed on the $2,000,000 in the 14th year to the Cieneguita Owner to keep the option in good standing. The Company renegotiated the payment due May 6, 2007, to $60,000 payable on November 6, 2007, which was paid and the balance of $60,000 was paid on December 20, 2007. Once the full $2,000,000 payment has been made, we will own the concessions. Yearly payments will need to be made from working capital. We do not have the capital at this time to fund the ongoing payments. We will need to raise the funds through the sale of debt or equity. We do not have any sources for such capital at this time. In the alternative, if Cieneguita is put into production, of which there is no guarantee, we must pay the Cieneguita Owner $20 per ounce of gold produced, if any, from the Cieneguita concessions up to the total $2,000,000 due. In the event that the price of gold is above $400 per ounce, the property payments payable to the Cieneguita Owners from production will be increased by $0.10 for each dollar increment the spot price of gold trades over $400 per ounce. The total payment of $2,000,000 does not change with fluctuations in the price of gold. Non-payment of any portion of the $2,000,000 total payment will constitute a default. In such case, the Cieneguita Owners will retain ownership of the concessions, but we will not incur any additional default penalty. MRT retained no interest in the Cieneguita Property.  (2)MRT assigned Sunburst de Mexico, with the consent of  Compañía Minera (the Guazapares Owner) MRTs rights and obligations concerning the Guazapares Property, including the exclusive option under the Guazapares Option Agreement, for a term of four years, to purchase seven of the Guazapares concessions upon payment of $910,000. In return, Sunburst de Mexico granted MRT a 2.5% Net Smelter Royalty (NSR) and the right to extract from the Guazapares concessions up to 5,000 tons per month of rock material; this right will terminate on exercise of the option to purchase the concessions. MRT retained no interest in the Guazapares Property.  (3)Sunburst de Mexico purchased two of the Encino Gordo concessions from MRT for a price of 1,000 pesos (approximately US$90), and MRT assigned to Sunburst de Mexico a first right of refusal to acquire three additional Encino Gordo concessions. The Company has the option to acquire 100% of the additional three Encino Gordo concessions subject to a 2.5% NSR and the obligation to make the scheduled property payments totaling $500,000.   5    (4)MRT assigned to Sunburst de Mexico, for a term of 60 months, commencing from June 25, 2004 (the Option Period), with the consent of Minera Rachasa, S.A. de C. V. (the San Francisco Concessions Owner), MRTs rights and obligations acquired under the San Francisco Option Agreement, including the option to purchase the San Francisco concession for a price of $250,000 (the Purchase Price). MRT and the San Francisco Concessions Owner reserved a combined 2.5% NSR. MRT reserved no other rights in the San Francisco concessions. To maintain the option, Sunburst de Mexico assumed the obligation to pay to the San Francisco Concessions Owner cumulative annual payments totaling $90,000; if the option is exercised prior to the expiration of the Option Period by payment of the Purchase Price, the obligation to pay the annual payments will be terminated.  (5)MRT assigned to Sunburst de Mexico, with the consent of the Rafael Fernando Astorga Hernández (San Antonio Concessions Owner), MRTs rights and obligations acquired under the San Antonio Option Agreement, including the option to purchase the San Antonio concessions for a price of $500,000 (the Purchase Price) commencing from January 15, 2004, the date of signing of the San Antonio Option Agreement (the Option Period). MRT and the San Antonio Concessions Owner reserved a combined 2.5% NSR to be paid to them. MRT reserved no other rights in the San Antonio concessions. To maintain the option, Sunburst de Mexico assumed the obligation to pay to the San Antonio Concessions Owner cumulative annual payments totaling $150,000; if the option is exercised prior to the expiration of the Option Period by payment of the Purchase Price, the obligation to pay the annual payments will be terminated. The San Antonio Concessions Owner reserved the right to extract from the San Antonio concessions up to 50 tonnes per day of rock material; this right will terminate on the date of the exercise of the option.   Also on August 25, 2005, the parties signed an operators agreement (which has subsequently been cancelled, as discussed below) pursuant to which Sunburst de Mexico engaged MRT as the operator of the Cieneguita Property. MRT was to be paid an operators fee based on the functions performed and an operators bonus equal to 10% of the net proceeds of production if operating cash costs did not exceed $230 per ounce of gold produced from the Cieneguita Property. The operators fee was to be: (a) with respect to programs: (i) 2% for each individual contract which expressly includes an overhead charge by the party contracted; (ii) 5% for each individual contract which exceeds $50,000; (iii) 15% of all other costs not included; (b) with respect to construction: 2 % of all other such costs; (c) 3.5% of operating costs after the completion of construction on Cieneguita. MRTs duties were to (a) comply with the provisions of all agreements or instruments of title under which the Cieneguita Property or assets were held; (b) pay all costs properly incurred promptly as and when due; (c) keep the Cieneguita Property and assets free of all liens and encumbrances arising out of the mining operations and, in the event of any lien being filed as aforesaid, proceed with diligence to contest or discharge the same; (d) perform such assessment work or make payments in lieu thereof and pay such rentals, taxes or other payments and do all such other things as may be necessary to maintain the Cieneguita Property in good standing, (e) maintain books of account in accordance with generally accepted accounting principles provided that the judgment of the operator, as to matters related to the accounting, shall govern if the operators accounting practices are in accordance with accounting principles generally accepted in the mining industry in Canada; (f) perform its duties and obligations in accordance with sound mining and engineering practices and other practices customary in the Canadian mining industry, and in substantial compliance with all applicable federal, state and municipal laws of Mexico; and (g) prepare and deliver reports.  The parties also signed a share option agreement pursuant to which Sunburst granted to MRT the exclusive option to acquire up to 100% of all outstanding shares of Sunburst de Mexico if Mexoro did not (a) comply with the terms of the underlying Cieneguita Option Agreement, the San Antonio Option Agreement, the San Francisco Option Agreement and the Guazapares Option Agreement and (b) loan to Sunburst de Mexico the amounts of $1,000,000 by December 31, 2005 and $1,000,000 by April 30, 2006. If the option to purchase 100% of the shares of the capital of Sunburst de Mexico were exercised by MRT, MRT was obligated to return to the Company for cancellation all of the shares of the capital of Mexoro issued by the Company to MRT and Mario Ayub. No finders fees were paid in these agreements.  On December 8, 2005, Mexoro and Sunburst de Mexico entered into a new agreement with MRT (the New Agreement) to exercise their option under the August 18, 2005 Sale and Purchase of Mining Concessions Agreement to obtain two mining concessions in the Encino Gordo region. The New Agreement modified the Companys property agreements, as discussed below. The following are additional material terms of the New Agreement:  (1)The share option agreement with MRT was cancelled.   6    (2)The Company granted MRT the option to buy all of the outstanding shares of Sunburst de Mexico for $100 if the Company failed to transfer $1,500,000 to Sunburst de Mexico by April 30, 2006. On April 6, 2006, MRT agreed to waive its option to purchase the shares of Sunburst de Mexico and also waived Mexoros obligation to transfer $1,500,000 to Sunburst de Mexico.  (3)The property agreements were modified to change the NSR to a maximum of 2.5% for all properties covered by the Agreements. The property agreements contained NSRs ranging from 0.5% to 7%.  (4)The Company agreed to issue 2,000,000 shares of the Company to MRT within four months of the date of the signing of the New Agreement. These shares were issued to MRT and its assignee, Etson, Inc., on February 23, 2006. This issuance fulfilled the Companys payment obligations under the previous property agreements.  (5)The Company agreed to issue 1,000,000 additional shares of the Companys common stock to MRT when the Cieneguita Property is put into production, if ever, and it reaches 85% of production capacity over a 90-day period, as defined in the New Agreement.  (6)The New Agreement gave Sunburst de Mexico the option to obtain three additional concessions in the Encino Gordo region.  (7)The operators agreement with MRT was cancelled.  Unless explicitly superseded or terminated by the New Agreement, as discussed above, the terms of the Companys existing property agreements remain in effect. Under the New Agreement, MRT has assigned to Sunburst de Mexico rights it acquired in a contract with Corporativo Minero. MRT entered into an agreement with Corporativo Minero on January 12, 2004 by which it acquired the right to explore and exploit the Cieneguita Property and purchase it for $2,000,000. MRT paid $150,000 upon execution of the agreement and two months later paid $200,000. This agreement gave MRT the exclusive right and option, but not the obligation, to purchase, during the term of the mining concessions of the property, an undivided 100% title to the mining concessions and the exclusive right to carry out mining activities on any portion of the mining concessions. Under our agreements with MRT, MRT has assigned this agreement and all of its rights and obligations there under, to us. As of the date of this annual report, $590,000 of the $2,000,000 has been paid to Corporativo Minero by MRT ($350,000 paid) and Sunburst de Mexico ($120,000 paid in no production penalty fees). Sunburst de Mexico had the obligation of bringing the property to production on or prior to May 6, 2006. The Cieneguita Property was not in production as of May 6, 2006 and, therefore, Sunburst de Mexico had the obligation to pay $120,000 to Corporativo Minero on May 6, 2006 to extend the contract. Through discussions with Mexoro, Corporativo Minero agreed to reduce the obligation to $60,000, of which $10,000 was paid in April 2006. Sunburst de Mexico was then required to pay the remaining $50,000 by May 6, 2006. We made this payment to Corporativo Minero and the contract was extended. The Company renegotiated the payment due May 6, 2007, to $60,000 payable on November 6, 2007, which was paid and the balance of $60,000, which was paid on December 20, 2007. Payment of $60,000 on the $120,000 that was due to the concession holders was made in May 2008 with the balance of the payment due to be paid in June 2008. We have the obligation to pay a further $120,000 per year on May 6 of each year, until the total of $2,000,000 is paid. We are currently not in default on our payments.  If the property is put into production, of which there is no assurance, then the contract calls for the remaining payments to be paid from the sale of gold, up to a total of $2,000,000. The payments, if the property should go into production, would be as follows: The remainder of the $2,000,000 payment would be paid out of production from the Cieneguita Property at a rate of $20 dollars per ounce of gold sold. However, in the event that the price of gold exceeds $400, then Sunburst de Mexico would be required to pay an additional $0.10 per each ounce for every dollar the spot price of gold trades over $400. Once $2,000,000 is paid, there is no further obligation to Corporativo Minero. Non-payment of any portion of the $2,000,000 total payment will constitute a default. In such case, Corporativo Minero would retain ownership of the concessions, but we will not incur any additional default penalty. Corporativo Minero has the obligation to pay, from the funds they receive from us, any royalties that may be outstanding on the properties from prior periods. Corporativo Minero has informed us that there were royalties of up to 7% NSR owned by various former owners of the Cieneguita Property. They have informed us that the corporations holding those royalties have been dissolved and that there is no further legal requirement to make these royalty payments. We can make no assurance that we will not ultimately be responsible to pay all or some of the 7% NSR to these former royalty holders if the property was ever put into production and Corporativo Minero did not make the payments to the royalty holders. MRT no longer has any ownership interest or payment obligations with respect to any of the concessions discussed herein.   7   On May 15, 2006, Sunburst de Mexico entered into an exploration contract with Jose Maria Rascon Rascon and Sabino Amador Rascon Polanco and with Rene Muro Lugo (all three representatives constitute the Concessionaires) for the Segundo Santo Nino concession on the Sahauyacan Property. Each concession representative owns 33.3% of the total Segundo Santo Nino title. The Company must pay the Concessionaires a total of $255,000 for this concession. The total payments to acquire 100% of this concession are as follows: all payments up to November 15, 2007 totaling $50,000 have been paid, May 15, 2008 - $15,000, November 15, 2008 - $20,000, May 15, 2009 - $20,000, November 15, 2009 - $30,000 and May 15, 2010 - $120,000.  On June 21, 2006, Sunburst de Mexico entered into an Exploration and Sale Option Agreement of Mining Concessions (the Exploration Agreement) with Minera Emilio for mineral concessions in Chihuahua, Mexico on the Sahauyacan Property. Minera Emilio owns 100% of the Sahauyacan Property. There is no affiliation between Minera Emilio and the Company or its officers, directors or affiliates.  Under the Exploration Agreement, Minera Emilio granted the Company the exclusive right to conduct exploration on the Sahauyacan Property. The Company must pay Minera Emilio $282,000 in the following manner:  (i) $30,000 payable at the execution of the Agreement (this amount has been paid); (ii) $2,500 per month as of August 21, 2006, and so on for each month elapsed for twelve months, on the 21st day of each month  (these amounts have been paid); (iii) $3,500 per month as of the beginning of the second yearly term, that is, as of August 21, 2007, and every month, on the 21st day of each month, for the whole second yearly term (the first 7 months of these payments have been made and are in good standing for a total amount of $24,500); and (iv) $5,000 monthly, during the third, fourth, and fifth yearly term, on the 21st. day of each month. The term of the Exploration Agreement is five years from the date of execution by Minera Emilio, which is June 22, 2011. While Minera Emilio signed the agreement on June 22, 2006, further negotiations occurred and the Company signed the agreement on October 24, 2006. Non-payment of any of the payments owed would constitute a default under the Exploration Agreement. As of the date of this annual report, we have not been given notice of any default. In the event we were given notice and default was not cured in a timely manner, the Company would lose the right to explore on the Sahauyacan Property and would lose the option to purchase the mineral concessions.  Minera Emilio also granted the Company the option to purchase the mineral claim. The option shall expire on June 22, 2011. The Company must provide Minera Emilio with 30 days written notice before exercising the option. The purchase price of the mineral claim is $300,000 or the equivalent of $500,000 in restricted shares of common stock of Mexoro based upon the market value of such shares during the 30 days preceding notice of the intent to exercise the option. The Company must complete a feasibility survey within three years from the date the option is exercised.  After exercising the option, the Company must pay Minera Emilio royalties on any mineral ore that is sold from the mineral claim. The rate of the royalties due varies based on the price of gold on the London Metal Exchange (the Price). If the Price is less than or equal to $600 per ounce, the royalty due is 3% of Net Revenue. If the Price is higher than $600 per ounce, the royalty due is 4% of the Net Revenue. Net Revenue is calculated by subtracting smelting expenses, added value taxes, and all other taxes on production sales from revenue.  On January 25 2008, Sunburst de Mexico entered into an exploration and option agreement with Maria Luisa Wong Madrigal for mineral concessions under the La Maravilla project on the Sahauyacan Property. The Company must pay Maria Luisa Wong Madrigal $600,000 in the following manner: (i) $33,000  January 25, 2008 (paid); (ii) $33,000  July 25, 2008; (iii) $34,000  January 25, 2009; (iv) $500,000  at the option to purchase the concession or in 36 months  January 25, 2010.  The La Maravilla project concessions are subject to royalties of 2.0% over net liquidations, which may be acquired by Sunburst de Mexico for $400,000 before commercial production is initiated. This exploration and option agreement has yet to be filed before the Mining Public Records Office as of the date of this report.  In addition, we intend to identify and obtain options on additional gold and silver properties within the Chihuahua region, if possible. We will utilize our managements contacts in the Mexican mining community in order to find potential properties that may be available. There can be no assurance that we will be able to obtain any additional property on acceptable terms or at all.  On September 19, 2007, Sunburst de Mexico, MRT and Mexoro entered into an Agreement to Defer Guazapares Property Payments. This agreement modifies the agreement entered into by MRT and Sunburst de Mexico on August 18, 2005 in regard to the Guazapares concessions in Mexico.  Under the original agreement entered into by the parties on August 18, 2005, Sunburst de Mexico was obligated to pay MRT US$60,000 on August 2, 2006 as part of the payments required for the  8   purchase of eight mineral concessions in the Guazapares area of Mexico. On July 18, 2006 the parties agreed to extend the due date for ninety days until October 31, 2006. MRT agreed to re-extend the due date for such payment by 120 days until February 28, 2007 and then again to May 31, 2007. An oral agreement extended the due date to August 31, 2007.  Pursuant to the same agreement entered into by the parties on August 18, 2005, Sunburst de Mexico was obligated to pay MRT a further amount of US$140,000 on August 2, 2007 to purchase the Guazapares concessions.  MRT is a related party as it is controlled by Mario Ayub, the President and a Director of Mexoro.  Under the September 17, 2007 agreement, Sunburst de Mexico, MRT and Mexoro agree that:  ●Any and all property payments regarding Guazapares, then owing to MRT or which would otherwise become due by December 31, 2007, will be deferred until such time as Sunburst de Mexico and Mexoro have sufficient funds to make the payments, in the opinion of the disinterested directors of Mexoro and,  ●Mexoro would issue 250,000 shares to MRT and/or assignees, in consideration for the deferral of any and all Guazapares property payments then outstanding or those arising on or before December 31, 2007.   Principal Products  Our principal product is the exploration for, and, if warranted, the mining and sale of precious minerals. Because our properties are in the exploration stage, there is no guarantee that any ore body will be found.  Mario Ayub, the Companys chief operating officer, is a past president of the National Miners Association of Mexico and of the Chihuahua Miners Association, and through his network, he has been able to discuss and obtain information on potential mining properties. A potential mining property is identified first by a visit to the property by a geologist. If the property has potential based upon the geologists findings, another visit is made to gather more information by taking surface samples and mapping the property. Also, geophysical work (in this case mineral exploration techniques using electromagnetic instruments to measure the conductivity of the rocks underground) may be performed before entering into the negotiation process for a particular property.   Glossary of Certain Mining Terms  ASSAY -- A chemical test performed on a sample of ores or minerals to determine the amount of valuable metals contained.  AURIFEROUS ZONE  An area of gold bearing rock.  BRECCIA -- A rock in which angular fragments are surrounded by a mass of fine-grained minerals.  COLUMN TEST -- The process of putting sample ore in a PVC pipe 500 centimeters in diameter and 2-3 meters high and applying lime and a cyanide solution. The purpose of a column leach test is to collect kinetic information on the ore being evaluated so that scale-up equations can be validated which will allow the projection of the commercial heap leach operation's performance under different operating scenarios.  DEVELOPMENT DRILLING -- Drilling to establish accurate estimates of mineral reserves.  DILUTION (mining) -- Rock that is, by necessity, removed along with the mineralized ore in the mining process, subsequently lowering the grade of the ore.  EPITHERMAL DEPOSIT -- A mineral deposit consisting of veins and replacement bodies, usually in volcanic or sedimentary rocks, containing precious metals, or, more rarely, base metals.  EXPLORATION -- Work involved in searching for ore, usually by sampling rocks, drilling or driving a drift.  HEAP LEACHING -- A process involving the percolation of a cyanide solution through crushed ore heaped on an impervious pad or base to dissolve minerals or metals out of the ore.   9   HIGH GRADE -- Rich ore. As a verb, it refers to selective mining of the best ore in a deposit.  HYDROTHERMAL -- An adjective applied to heated or hot magmatic emanations rich in water, to the processes in which they are concerned, and to the rocks, ore deposits, alteration products and springs produced by them.  INDICATED MINERAL RESOURCE -- An Indicated Mineral Resource is 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.  INFERRED MINERAL RESOURCE -- An Inferred Mineral Resource is 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.  LEACHABILITY  The ability for cyanide solution in a heap leach operation to leach the desirable minerals from the host rock and allow for recovery at an economic level.  MINERAL -- A naturally occurring homogeneous substance having definite physical properties and chemical composition and, if formed under favorable conditions, a definite crystal form.  MINERAL RESERVE  A mineral reserve is the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. This 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 may occur when the material is mined.  MINERAL RESOURCE  A mineral resource is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals 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.  MINERALIZATION -- The act or process of mineralizing.  MINERALIZED MATERIAL OR DEPOSIT -- A mineralized body which has been delineated by appropriate drilling and/or underground sampling to support a sufficient tonnage and average grade of metal(s). Under SEC standards, such a deposit does not qualify as a reserve until a comprehensive evaluation, based upon unit cost, grade, recoveries, and other factors, concludes economic feasibility.  MINING CONCESSION -- A term used to describe an area of land for which the owner of the concession has the right to explore for and develop mineral deposits. The rights to and ownership of the minerals in the concession are granted, in our case, by the Mexican Government to the former owners who then either transferred or optioned them to us. In Canada and the United States, the term is commonly referred to as a Mineral Right or Mining Claim.  NET SMELTER RETURN (NSR) -- A share of the net revenues generated from the sale of metal produced by a mine.  ORE -- Mineralized material that can be mined and processed at a positive cash flow.  OREBODY -- A natural concentration of valuable material that can be extracted and sold at a profit.  PRELIMINARY FEASIBILITY STUDY -- A preliminary feasibility study is a comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, has been established and an effective method of mineral processing has been determined, and includes a financial analysis based on reasonable assumptions of technical, engineering, legal, operating, economic, social,  10   and environmental factors and the evaluation of other relevant factors which are sufficient for a qualified person, acting reasonably, to determine if all or part of the mineral resource may be classified as a mineral reserve.  QUALIFIED PERSON  An individual who is an engineer or geoscientist with at least five years of experience in mineral exploration, mine development or operation or mineral project assessment, or any combination of these; has experience relevant to the subject matter of the mineral project and the technical report; and is a member or licensee in good standing of a professional association.  RECLAMATION -- The restoration of a site after mining or exploration activity is completed.  ROYALTY -- An amount of money paid at regular intervals by the lessee or operator of an exploration or mining property to the owner of the ground. The royalty, generally, is based on a certain amount per ton or a percentage of the total production or profits. Also, the fee paid for the right to use a patented process.  SILVER PAN AMALGAMATION MILL -- The raw ore is wet crushed with stamps, the crushed ore is separated from the slurry in a settling tank and then the crushed ore is charged with mercury (approximately 10% of the weight of the ore) in the amalgamation pan. The amalgam is separated from the slurry and the silver and gold is separated from the amalgam with a retort.  STRIKE LENGTH  The actual or estimated length, generally measured in meters, of a mineralized structure.  VEIN -- A mineralized zone having a more or less regular development in length, width and depth, which clearly separates it from neighboring rock.  Properties  All of the properties discussed below are located in the State of Chihuahua, Mexico. The following map illustrates the locations of Chihuahua and of the properties:  Location of Cieneguita, Encino Gordo and Guazapares Properties in Chihuahua, Mexico  11   [mexoro_amendment10ka2008001.jpg]  Cieneguita Property  Property Location  The Cieneguita Property is located in the Baja Tarahumara in Cieneguita Lluvia De Oro, an area of canyons in the Municipality of Urique, in southwest Chihuahua, Mexico. The property is located within one half mile of the small village of Cieneguita Lluvia de Oro. Access to the property is by an all weather dirt road. There is available electrical power for the property generated by diesel generators at Cieneguita Lluvia de Oro.  Claim Status and Licensing  The Cieneguita Property is currently owned by Corporativo Minero. Sunburst de Mexico has the option of purchasing the concessions under the payment plan discussed below. The concessions of this project cover a total area of 822 hectares (approximately 2,031 acres). The following table is a summary of the concessions on the Cieneguita Property:  12    Lot NameTitle NumberArea (Ha)Term of Validity(2)Royalties and PaymentsAurifero196356492.007/16/1993 to 7/15/2043(1)Aurifero Norte19615360.007/16/1993 to 7/15/2043(1)Aquilon Uno208339222.10779/23/1998 to 9/22/2048(1)La Maravilla19047948.004/29/1991 to 4/24/2041(1)  (1)           The Cieneguita concessions are all under an option to purchase for $2,000,000 of which $590,000 has been paid. MRT paid $150,000 upon execution of the agreement with Corporativo Minero and two months later paid $200,000. Because the Cieneguita property was not in production by May 6, 2006, Sunburst de Mexico was required to pay $120,000 to Corporativo Minero to extend the contract. Through discussions with Mexoro, Corporativo Minero agreed to reduce the obligation to $60,000, of which $10,000 was paid in April 2006. Sunburst de Mexico was then required to pay the remaining $50,000 by May 6, 2006. We made this payment to Corporativo Minero so the contract has been extended. The Company renegotiated the payment due May 6, 2007, to $60,000 payable on November 6, 2007, which was paid and the balance of $60,000 was paid on December 20, 2007. We paid $60,000 on May 12, 2008 of the $120,000 due on May 6, 2008, with the balance to be paid in June 2008. We are not in default on our payments. We have the obligation to pay a further $120,000 per year for the next 13 years and the balance of payments in the 14th year, until the total of $2,000,000 is paid. If the property is put into production, of which there is no assurance, then the contract calls for the remaining payments to be paid from the sale of gold, to avoid termination of the agreement.  The payments, if the property should go into production, would be as follows: The remainder of the $2,000,000 payment will be paid out of production from the Cieneguita Property at a rate of $20 dollars per ounce of gold sold. However, in the event that the price of gold is in excess of $400, then Sunburst de Mexico is required to accelerate payments by an additional $0.10 per each ounce for every dollar of gold priced over $400. The total payment we are liable for is $2,000,000. Once that amount is paid, we have no further obligation to Corporativo Minero. Corporativo Minero has the obligation to pay, from the funds they receive from us, any royalties that may be outstanding on the properties from prior periods. Corporativo Minero has informed us that there were royalties up to 7% NSR owned by various former owners of the property. They have informed us that the corporations holding those royalties have been dissolved and that there is no further legal requirement to make these royalty payments. We can make no assurances that we will not ultimately be responsible to pay all or some of the 7% NSR to these former royalty holders if the property were ever put into production and Corporativo Minero did not make the payments to the royalty holders. However, we do not see this potential for additional royalty payments as a material risk to us.  (2)           Amendments to the Mexican mining laws took effect with the publication on December 21, 2005, including certain amendments to the Ley Federal de Derechos, the act that sets forth the mining taxes' rates. Effective January 1, 2006, this legislation has converted all of the former exploration and exploitive concessions in Mexico, which carried maximum lives of six years, and  25 years, respectively, into general concessions with a 50 year life from their date of registration with the Mining Registry. The concessions are automatically registered as soon as the concession mining rights are paid and no further paper work is required. Our claims are currently in good standing and held by Sunburst de Mexico. There will be no special documents sent to us to reflect the change.  In April 2006, we applied to the Mexican government for a change of use of land permit for 30 hectares of the La Maravilla concession. La Maravilla is the concession that contains the mineralized rock that is the main interest of our exploration on the Cieneguita Property. La Maravilla currently has no activity on it other than our exploration program. The purpose of the change of use permit is to allow us, if necessary, to extract the rock from this concession for the purposes of processing to extract the precious metals that may be contained therein. We made the application in advance of any known reserves being discovered on the Cieneguita Property. We cannot assure that we will have sufficient ore reserves, if any, to commence extraction. This permit required negotiations with the government and municipality concerning such things as the removal of timber, building and maintaining roads and reclamation. In January 2007, the government agency issued the change of use permit, and we subsequently made the required payment of approximately $67,000 (720,000 Mexican pesos).  In July 2006, we submitted an environmental impact study and a risk analysis study to the Mexican government for a permit to build a heap leach mining operation on the Aurifero concession of the Cieneguita Property. The purpose of this permit is to allow us to construct an ore processing facility through heap leach mining methods. We do not have any ore reserves on the Cieneguita Property and applied for permits in advance of any conclusive results to partly limit our financial exposure searching for precious metals. In January 2007, the necessary permits to allow for the building and operation of a heap leach operation were granted to the Company. If we are unable to extract and process our discoveries, if any, then there is no need to continue exploration.    13   History  The Cieneguita mine was in limited production in the 1990s. Over a four-year period, the Cieneguita mine was operated by Mineral Glamis La Cieneguita S. de R.L. de C.V. (Glamis), a subsidiary of the Canadian company Glamis Gold Ltd. (Glamis Gold). Glamis was recently acquired by Goldcorp Inc. According to Glamis records, Glamis mined and processed 198,000 tonnes of mineralized rock grading 2.2 g/t gold on the property in 1995, ceasing production shortly thereafter. At that time, Corporativo Minero, the operator of the mine for Glamis, acquired the property. MRT entered into an agreement with Corporativo Minero on January 12, 2004 pursuant to which MRT acquired all of the mineral rights from Corporativo Minero to explore and exploit the Cieneguita concessions and to purchase them for $2,000,000. Under our agreements with MRT, MRT has assigned this agreement to us. As of the date of this annual report, $590,000 of the $2,000,000 has been paid to Corporativo Minero. MRT paid $150,000 upon execution of this agreement and two months later paid $200,000. We are obligated to make yearly payments on these concessions to Corporativo Minero until the $2,000,000 has been paid. Also, the agreement calls for the balance of the purchase price remaining to be paid out of production, if any, on Cieneguita at a rate of $20 per ounce of gold sold. However, in the event that the price of gold were to exceed $400, then Sunburst de Mexico would be required to pay an additional $0.10 per each ounce for every dollar gold trades over $400.  If Cieneguita is never put into production, we are still obligated to pay the $120,000 per year until the $2,000,000 is paid. Sunburst de Mexico made payments to the property owners of $10,000 in April 2006 and $50,000 in May 2006 in lieu of its obligation of bringing the property to production on or prior to May 6, 2006. Sunburst de Mexico has the obligation to pay $120,000 per year for the years subsequent to May 6, 2006 until the $2,000,000 is paid or the mine is put into production, if ever, in which case the remaining amount owed would be paid out of any production of the property, to avoid termination of the agreement. The Company renegotiated the payment due May 6, 2007, to $60,000 payable on November 6, 2007, which was paid, and the balance of $60,000 which was paid on December 20, 2007. The Company paid $60,000 of the $120,000 due on May 6, 2008, with the balance to be paid in June 2008. We are not in default on our payments. On termination of the agreement, there would be no further obligations by Mexoro to any parties other than assuming responsibility for any reclamation work that may need to be done as a result of exploration or mining activity if any should occur.  Geology  The Cieneguita Property is located in the mid-Tertiary domain of the Sierra Madre Occidental of Chihuahua State, Mexico. This region is dominated by felsic ignimbrites and reportedly represents the largest field of felsic volcanics in the world (Jones, 2006).  Based on the work of Jones (2006), who spent approximately two weeks on the Cieneguita Property in mid-November of 2006, the Cieneguita Property appears to lie along the eastern margin of a well-defined but previously unidentified collapse caldera named the Cieneguita Caldera. The Cieneguita Caldera appears to be part of a larger caldera complex which exhibits a rough north-south trend, which may, at its southern end, include the El Sauzal project (a producing mine). As suggested by Jones (2006), this north-south trending caldera complex may have developed along a broad north-south arc related to post-Laramide collapse and extension which occurred throughout western North America. The identification of this nested caldera is considered important as the mineralization on the Cieneguita Property appears to be controlled by volcano-structural features related to the Cieneguita Caldera and the caldera complex in which it lies (Jones, 2006).  Field mapping by Jones (2006) has indicated that the Cieneguita Caldera is approximately 15 kilometers in width and possibly up to 32 kilometers in length. This mapping also identified a number of diagnostic features of calderas. These include:  · Significant thicknesses of horizontally stratified tuff  interpreted as intracaldera deposits. · Morphologic/topographic break between ponded and outflow ignimbrites  interpreted as the topographic caldera wall. · Ring structure (based on satellite imagery). · Landslide deposits of caldera wallrocks that have been engulfed by intra-caldera tuffs in the form of megabreccias.  Jones (2006) has suggested that the Cieneguita deposit lies along the (eastern) topographic rim of the Cieneguita Caldera. This interpretation is based on an important litho-structural break between outward (easterly) dipping outflow tuffs and horizontally stratified intra-caldera tuffs. Furthermore, erosion appears to have reduced the rim to the level of the ring-fracture zone. This is based on a number of well-defined north-south striking faults and shears in the caldera wall (Jones, 2006).   14   Lithotypes  A number of lithologies have been identified on the Cieneguita Property and have been summarized by Jones (2006) below.  The extra-caldera (caldera wall) lithologies include (from oldest to youngest) a lower rhyolite tuff, an andesite vitrophyre, an upper rhyolite tuff and basaltic dykes.  Field observations indicate that the lower two units and portions of the third were deposited prior to caldera formation. Landslide blocks of andesite vitrophyre and portions of the upper rhyolite can be found engulfed by intra-caldera tuffs.  These units show relatively conformable dips in sequential beds demonstrating that they were deposited on the margins of the volcanic edifice and predate caldera formation.  Lower rhyolite tuff: The lower rhyolite unit includes at least two welded tuff sequences that are nearly indistinguishable from the upper rhyolite sequence. The rhyolites contain a low percentage but consistent amount of lithic fragments. The units thickness is unknown.  Andesite vitrophyre: This unit is a basaltic to andesitic flow which is exposed for nearly two kilometers along the strike of the caldera wall. It is strongly vitric to the north, moderately vitric in the centre and largely devitrified at the project area and to the south. The unit contains an even abundance of relatively calcic plagioclase crystals while the mafic component is predominately hornblende with minor pyroxene and biotite. This unit acts as the most important marker horizon in the caldera wall with an estimated thickness of 65-80 meters.  Upper rhyolite tuff: The base of this unit is defined by locally well graded basal surge deposits that grade upwards into tuffs with a very high percentage of lithic fragments including blocks up to several metres in diameter. The unit grades upward into a high lithic load welded tuff which marks the lowest of at least three welded tuff packages. The base of this unit occurs as landslide blocks on the Cieneguita Property indicating that it at least partially predates the Cieneguita Caldera. The three overlying welded tuff packages may be correlative with the Cieneguita Caldera itself  Basalt dykes: A single 6 meter wide basaltic dyke has been mapped cutting the upper rhyolite tuff sequence. This dyke cuts the upper caldera fill facies of the upper rhyolite sequence and is therefore considered to be post-Cieneguita Caldera formation.  The intra caldera lithologies are found within the Cieneguita Caldera and include a megabreccia sequence and caldera infill sequence.  Megabreccia Sequence: This unit is characterized by large blocks of caldera wall that collapsed into the caldera during caldera collapse. At Cieneguita, a portion of the caldera wall, consisting of both the andesite vitrophyre and the basal units of the upper rhyolite sequence, slid into the caldera and were engulfed and injected by intra caldera ash flow deposits. Within one of the larger blocks contained in the megabreccia, the contact between the andesite vitrophyre unit and the upper rhyolite tuffs strikes through the center of the formally mined area of Pit 1. This contact is thought to have had an important control on the emplacement and localization of the gold mineralization.  Caldera Infill Sequence: This unit includes rocks that were formed by volcaniclastics that were vented and deposited during caldera formation. This unit can be subdivided into two groups; basal surge deposits and lithic rhyolite tuffs.  i)Basal surge deposits exhibit dune-like forms consisting of moderately to well sorted beds of well rounded grains of siliceous volcanic rocks. They are thought to be shock deposits formed from the air blast of the initial caldera explosion.  ii)Lithic rhyolite tuffs overlying the basal surge deposits consist of horizontally stratified pyroclastics that were deposited into the Cieneguita Caldera. The tuffs include a variable, heterogeneous lithic load of pre-existing volcanic rocks and megabreccia. The unit varies from grey (when unconsolidated) to purple-salmon colored where they are more indurated and welded.   15   Intrusives: The youngest rocks found at Cieneguita are the intrusives, which cut the caldera infill sequences. They occur as dykes and sills ranging in width from one to eight meters. The three types of intrusives that have been identified are felsites, composite basalt-rhyolite vent breccias, and basalts.  i)Felsite dykes can be observed along the south ridge of Cieneguita as two dykes with an east-northeast strike dipping moderately to steeply to the northwest. They clearly crosscut the intra-caldera tuffs and are nowhere brecciated, altered or veined. They are characteristically fine grained and siliceous with sanidine and bi-pyramidal quartz phenocrysts.  ii)The composite basalt-rhyolite vent breccias/dykes commonly contain a high percentage of lithic and pumice clasts, compositional banding and spherulites. Quartz veining, specularite and heavy hematite dustings are locally quite intense within and adjacent to these intrusions suggesting they may be mineralized. They are thought to have formed by the commingling of actively erupting basaltic and rhyolitic melt.  iii)Basalt is present as dykes and irregular intrusions exhibiting a chocolate brown color and fine-grained homogenous texture. They show no signs of deformation or alteration and are thought to be post-mineralization.  Structure  The most important structures in a regional sense are those that controlled the development of the Cieneguita Caldera. The elongate shape of the Cieneguita Caldera suggests that it formed along a NNW-SSE trending axis of regional collapse and extension at the end of the Laramide. Extension continued during and after caldera formation as evidenced by normal faults that offset both pre-caldera and intra-caldera rocks down to the west (Jones, 2006).  The primary structural controls at the mineralized area on the Property trend WSW-ENE as indicated by extensive sheeted fractures and a few faults. The most important of these structures identified thus far is a fault which strikes through the centre of Tajo 1 resulting in the down faulting of the rhyolite/andesite contact to the north. Intense quartz veining and elevated gold values are associated with this fault indicating that it also acted as a conduit for gold-bearing fluids. Notably, this fault is paralleled by two of the felsite dykes described earlier. Jones (2006) suggests that these are deep-seated pre-caldera extensional structures which were reactivated during resurgent magmatism within a nested caldera to the west of the town of Cieneguita and subsequently exploited by the late felsite dykes.  Jones (2006) considers NNW to NNE striking high-angle faults to be important from an economic standpoint. He suggests that mineralization may be well off the main trend as a result of these structures acting as permeable pathways for migrating gold-bearing fluids.  Deposit Types  There are three main deposit types that are considered relevant to the Cieneguita Property: epithermal vein, mesothermal vein and porphyry. These are briefly discussed below.  Epithermal  High sulphidation epithermal deposits occur as veins, vuggy breccias and sulphide replacements ranging from pods to massive lenses associated with high-level hydrothermal systems marked by acid-leached, advanced argillic and siliceous alteration. Metal associations in these deposits include variable amounts of precious (Au-Ag) and base (Cu-Pb-Zn) metals and variable gangue mineralogies. Irregular deposit geometries are the result of host rock permeability and the orientation of mineralized controlling structures. Multiple, crosscutting composite veins are common.  Recent research indicates that these deposits form in subaerial volcanic complexes or composite island arc volcanoes above degassing magma chambers. The deposits commonly contain multiple stages of mineralization, presumably related to periodic tectonism associated with increased intrusive activity and magmatic hydrothermal fluid generation (Panteleyev, 1996). The age of the deposits are commonly Tertiary to Quaternary, however, some deposits have been dated in Mesozoic and Paleozoic volcanic belts. The rare preservation of older deposits reflects rapid rates of erosion before burial of subaerial volcanoes in tectonically active arcs.   16   Rock types associated with epithermal deposits include a subaerial andesite-dacite-rhyodacite pyroclastics & flows as well as their subvolcanic intrusive equivalents. It is also thought that permeable intervolcanic sedimentary rocks can act as sites of mineralization. The country rock surrounding epithermal veins is commonly extensively altered even though the vein walls may be sharply defined. It is also not uncommon to find large, highly colored supergene gossans covering epithermal mineralization.  Mesothermal  Mesothermal gold vein deposits are commonly associated with crustal-scale strike slip faults and can be hosted in a wide variety of lithologies (Olsen et al., 1994). Analysis of fluid inclusions from samples of quartz veins yield average temperatures of more than 250 degrees Celsius. The veins are podiform, sheared, and concordant with the enclosing brittle to ductily deformed host rock and range in metamorphic grade from greenschist to amphibolite facies. Mesothermal gold deposits are found in proximity to major regional crustal-scale fault and fracture systems and are most often hosted in secondary or tertiary structures related to the regional scale structures. Gold is deposited via 250-400 C hydrothermal fluids which originate deep in the earths crust. The fault and fracture zones act as permeable conduits for the fluids to migrate. Gold is carried in solution until the fluid reaches a point where there is either a chemical reaction with the country rock or changes in temperature and/or pressure causes the gold to precipitate. The gold and various associated metals precipitate out of solution together with quartz, carbonate and various other accessory minerals. Structural evidence such as shears, folds in bedding or pinches, swells, and pods in quartz veins are characteristic of ductile deformation and can be often found at many Au-bearing mesothermal quartz veins. Au is often associated with pyrite, chalcopyrite and/or arsenopyrite and can occur as either free grains, within the pyrite/arsenopyrite structure or as electrum.  Porphyry  Porphyry deposits are typically low grade and large tonnage deposits that are both spatially and genetically to igneous intrusions (McMillan, 1991). The intrusive rocks that host these deposits are generally found to be felsic to intermediate. There are two primary processes that are responsible for porphyry-style mineralization. The first is the fracturing that results from the upwelling of magmatic derived hydrothermal fluids into the shallow crust where lower pressure conditions cause it to boil.  The build up of fluids occurs at the time the intrusion crystallizes, leaving behind an excess of fluids, some of which are derived from the intrusions contact metamorphic front. This aqueous fluid can potentially be enriched in gold, copper, or molybdenum. Further mineralization is achieved as the cooling magma chamber provides the heat engine to create hydrothermal convection cells. Metal enriched aqueous fluid circulates thought the stockwork and all fractures adding to and re-depositing these metals. Mineralization and alteration develop both in the intrusive and in the country rock. The core of the mineralizing system is dominated by a potassic alteration zone. Potassic alteration consists of potassium feldspar, biotite, and quartz. This grades out into the phyllic zone, in which the alteration is made up of quartz and muscovite (typically fine grained sericite). This grades out into the argillic zone, where the principal alteration is quartz and a variety of clay minerals. The propylitic zone rinds the argillic zone and consists of chlorite, epidote, and carbonate.  Mineralization  The gold mineralization identified to date at Cieneguita is localized exclusively within the intra-caldera rocks (megabreccias and infill tuffs). The mineralization is structurally controlled, occurring at the intersections of east-northeast structures and north-south extensional faults. Its spatial and temporal association with the felsic dykes suggest a genetic relationship between resurgent felsic magmatism (related to a younger nested caldera?) and gold mineralization.  The three main gold-related alteration assemblages that have been observed at Cieneguita include:  -Quartz +/- biotite +/- orthoclase +/- adularia +/- calcite-Quartz-sericite-pyrite  -Hematite-goethite  Quartz-biotite-orthoclase-adularia-calcite (Low Sulphidation)  This assemblage is a form of potassic alteration and is typically bordered by sericite-chlorite-epidote-alunite-clay alteration on the margins of quartz veins. With increased veining, the clay-sericite alteration merges into a more pervasive style of alteration. Associated sulphides are minimal. This variety of alteration is best observed in the andesite vitrophyre north of  17   the project area. The quartz, along with other minerals, are present as veins and sometimes as vain selvedge alteration which in areas of intense alteration is observed as being pervasive. This alteration is not known to be associated with significant sulphide mineralization.  Quartz-sericite-pyrite (High Sulphidation)  This alteration style occurs as a pervasive overprinting within and along structural and lithological breaks. The quartz-sericite-pyrite zones are commonly bordered by clay alteration.  Hematite-goethite  This alteration style is found locally along reaction fronts, fractures, and at the leading edges of silica veins. It locally overprints the first two assemblages. It occurs as massive red to orange-brown zones that are inferred to represent the deposition of and conversion of earlier sulphides to, hypogene iron oxides. Gold mineralization on the Cieneguita Property is most strongly associated with this alteration assemblage.  As noted by Jones (2006) the alteration and mineralization styles on the Property differ with rock type and geological setting. The two principle mineralized rock hosts are intra-caldera megabreccia and intra-caldera rhyolite tuff as discussed below:  Intra-caldera megabreccia  The megabreccia unit is the primary lithological host to mineralization at Tajo 1. Severe fracturing, faulting and brecciation during caldera formation were enhanced by the rheological contrasts between the brittle andesite vitrophyre and upper rhyolite tuff. These structures were subsequently infilled/injected by the highly fluid tuff which formed the matrix to the megabreccia. It was these faulted and tuff-injected zones that became the preferred pathways for mineralizing fluids.  Mineralization within the upper rhyolite tuff blocks of the megabreccia is typically accompanied by a strong quartz-sericite-pyrite alteration assemblage. It is described as having dark grey, highly siliceous, sulphide-rich, resistant bands that preserve relict bedding. Iron-oxide alteration crosscuts this alteration along fractures and is interpreted by Jones (2006) to represent a hypogene iron-oxide retrograde event. Quartz veins appear to be either paragenetically early and/or adjacent to the more intensely altered zones. Gold grades within this litho-alteration assemblage are consistently high (>>1 g/t) in these area  Mineralization within the andesite vitrophyre blocks of the megabreccia is found in faulted and tuff injected fractures. The brittle nature of the andesite resulted in extensive internal deformation in part related to devitrification. These structures were easily exploited during landslide collapse giving rise to 3D forked voids which were immediately injected with tuff and subsequently used as preferred pathways for mineralizing fluids. These pathways contain strong quartz-sericite-pyrite alteration bordered by extensive and pervasive argillic (clay) zones. In contrast to the rhyolite, the quartz-sericite-pyrite zones in the andesite show only moderate elevations in gold (0.5-0.7 g/t).  The leading edges of the stronger quartz-sericite-pyrite zones in the andesite are marked with intense iron-oxide fronts of heavy dark red to orange brown goethite-hematite. These iron-oxide fronts consistently carry higher (>2g/t) gold grades whilst adjacent quartz-sericite-pyrite zones are only weakly mineralized.  Intra-caldera rhyolite tuff  In comparison to the megabreccia unit the rhyolite tuffs are only weakly to moderately consolidated. The repercussions of this are that there is little brittle deformation such that would allow for focused fluid flow. Instead, the highly permeable tuffs exhibit broad and diffuse zones of alteration and mineralization.  Mineralization & alteration zones in the intra-caldera rhyolite tuffs are primarily controlled by east-northeast striking structures and, to a lesser degree, north-south structures. These zones are typically characterized by Iron oxide concentrations along and bordering the associated structure. Mineralization and quartz-sericite-pyrite alteration can also be found bordering felsite dykes. Trenching at Tajo 2 has suggested a gold-copper association based on the presence of chrysocolla. Distal to the quartz-sericite-pyrite zones, the rhyolite tuff takes on a chalky white appearance related to pervasive but diffuse clay alteration.  18    Glamis Gold performed a test pilot heap leach operation on the property in the mid 1990s. Exploration on the property is still in its early stages and significant work needs to be completed before any type of ore reserve calculations, if any, could be made. We have done some initial sampling and drilling on the La Maravilla concessions as described below.  A total of 51 diamond drill holes (6,700 meters) drilled by Cominco defined an auriferous zone approximately 1,000 meters long by 200 meters wide. Within the zone, two mineralized structures were drilled during an exploration program in 1981 and 1982. Later, two drilling programs were performed by Glamis: 135 holes were drilled during 1994 and 62 holes were drilled during 1997. Both programs confirmed the delineation of the two mineralized bodies. We have posted these reports from Cominco and Glamis on our website at www.mexoro.com. The continuing exploration conducted by the Company will focus on further delineating the oxide and mixed mineralization rock structures.

In April 2006, we completed a sampling of the property that included more than 500 meters of deep trenches from which we took comprehensive channel sampling. Each of the eight trenches was approximately 200 meters long and two to 10 meters deep spaced equally along the 1,000 meters strike length of the property. From the walls of these trenches, we took approximately 550 rock samples. One half of these samples were sent to ALS Chemexs laboratory in  19   Chihuahua for assaying. The sampling protocol followed the best mining practices. The purpose of the sampling was to further define the mineralized grade and potential of the property.  Our VP of Exploration believes that the mineralized material at Cieneguita is structurally controlled and hosted by breccias and tuffs varying from rhyolitic to dacitic in composition. The main mineralization and alteration zones have been developed in the intersection of WNW, NW and NE structures to the northwest (Pit 1 area) and to the southeast (Pit 2 area). These mineralized zones consist mainly of acid-sulphate alteration, including quartz-alunite and small and localized areas exhibiting residual or vuggy silica alteration zones and are interpreted to represent a high-sulphidation gold (±silver) system.  Phase 2 of exploration was designed to identify new veins and/or mineralized zones. The geological mapping and sampling activities carried out within phase 2 at Cieneguita has resulted in the discovery of gold zones in three different locations along Cieneguitas mineralized body. The three new gold locations have been identified just on the outlined limit of the known mineralized body opening the potential to the southeast in the Pit 1 South area, to the north in the Central area and to the north in the Pit 2 area, respectively.  Gold mineralization in the Pit 1 South area is mainly controlled by N35°E structures exhibiting quartz-sericite-pyrite alteration and small and localized areas with high clay content, where exposures allowed continuous chip sampling along roadcuts.  The new Central and Pit 2 North areas indicate that the mineralized material is primarily controlled by E-W and N30°W structures also exhibiting quartz-sericite-pyrite where pyrite has been completely oxidized. Small and localized areas of high clay content are also common.  From the samples taken at the Cieneguita Property we used 22 tonnes of the material to complete column tests to determine the leachability of the precious metals from the rock. In this test, the mineralized rock was placed in PVC tubes and different mixtures of a cyanide solution were dripped over the top of the columns at different flow rates. The results from these tests will help us to determine the most effective solution to use on the heap leach pads on the property. The tests, conducted by qualified geologists employed by MRT, were undertaken to determine if the metallurgy of the minerals would allow for economic recovery of the precious metals using a cyanide heap leach process. The tests were scientifically conducted and monitored for quality control and efficacy. The results of the column test indicate that up to 98% of the gold contained in the mineralized rock samples we took could be recovered from the mineralized rock if the mineralized rock is leached for a sufficient period of time. Under actual mining production conditions in the field, we would anticipate economic recovery levels from the mineralized rock to be approximately 70% to 75% recovery. The cost of the cyanide needed to recover gold above the 85% level would outweigh the value of gold recovered. We cannot guarantee that we will be able to reach this level of recovery. This is not an estimate of reserves on the property. Additional tests will be needed to determine the most effective crush size for the mineralized rock, the most cost effective flow rates of the cyanide and the most economical period of time for leaching.  According to our VP of Exploration, the results from the last mapping and sampling campaign provided evidence that the potential for the discovery of new areas with gold grades still remains open as shown by the discovery of the Pit 1 South, Central and Pit 2 North areas. This exploration program, consisting of detailed mapping and sampling on these three discovered zones, was completed in August 2007.  Concurrently with the surface exploration, a 4,000 meter diamond drilling program is being carried out in order to test the potential of those three new mineralized areas, to increase known mineralization and to characterize the gold mineralization contained within the sulphide zone. A total of 18 diamond core holes have been drilled (CI-01 to CI-18) for 3,606.91 core meters since drilling began at Cieneguita in early December 2007. All drill holes from this first phase drilling program have been focused on extending zones of high-grade gold mineralization identified by previous drilling programs (Glamis drilling program, 1994-1996). Drill hole CI-04 and CI-11 failed to intersect any economical mineralization.  Gold grades in the drilling were intersected by drillholes CI-02, CI-05, CI-06 CI-08, CI-09, and CI-10 as follows:  20

Drilling results have demonstrated the extension of the Cieneguita mineralized system at depth down at least to 250 meters where mineralization is mainly hosted by sulphides. The mineralization zone is still open to the south and to depth. Drilling program continues and a second stage drilling program has been proposed to define the complete mineralization system and provide Canadian National Instrument NI 43-101 compliant resource estimation report.  Despite these results, the Cieneguita Property has no known or estimated reserves.   21   Based on the recent results, management has decided to postpone putting the Cieneguita Property back into production. Management wants to complete drilling on the property and assess the new areas to ensure that the current mine design and the strategy of putting the property into production will provide the most value for the company.  Infrastructure  The town, near the former mine, has the following services: diesel generated electrical power, cellular phone service, radio communication (CB), a health center and a school. Because the property was previously in production, it has existing infrastructure that includes power, water, railroad transportation (within 20 kilometers), and a public, all weather road with access year round. The haul roads to the heap leach pads from the open pit area are in good condition and have been maintained by third parties since Glamis halted production, and the heap leach pads used in previous mining operations are still in place. It is our intention to use the existing pads and tailings site to reduce our costs to re-open the mine. Because of this existing infrastructure, we believe that the investment needed to put the mine into production would be less than the investment that would be required for a mine that was never in production. There are no additional equipment or facilities available to us on the property. Further study is required to review the feasibility and suggested extent of our use of the existing infrastructure of the old mine.  Budget  To date, we have incurred expenses of $1,544,000 due to exploration of the Cieneguita Property. Under the direction of our VP of Exploration, we commenced phase 2 of our exploration program in April 2008, which will be completed in July 2008. We budgeted $1,000,000 for the phase 2 exploration; including $50,000 for an additional geochemical sampling program and $50,000 for general administrative expenses. We have spent a total of $252,000 on this phase of exploration. We budgeted $1,835,000 for the cost of a 9,500 meter drilling program, including assaying and supervision. The drilling program at Cieneguita commenced on December 18, 2007 and we anticipate it to continue until the end of December 2008. See Plan of Operations in the Managements Discussion and Analysis section for further information.  Guazapares Property  Property Location  The Guazapares Property is located in the Barranca section of Chihuahua State in Mexico, and according to data published by the Government of Mexico, it is at the interphase between the two main volcanic groups that form the bulk of the Sierra Madre Occidental. The location is 220 kilometers to the southwest of Chihuahua City. An all weather dirt road traverses the property. The property is accessible year round by air, rail (within 20 kilometers) and road. The area has available diesel generated power and water.  The Guazapares Property, covering 1,980 hectares (approximately 4,893 acres), is in a mining district with a history of large ore deposits. A large ore deposit would be defined as a property capable of producing in excess of 50,000 ounces of gold equivalent per year.  Claim Status & Licensing  Sunburst de Mexico owns or has an option to purchase 100% of the Guazapares concessions, as indicated below. If our exploration is successful on the optioned concessions, then Sunburst de Mexico intends to exercise its option to acquire them. There is no penalty for not exercising our options. The concessions not owned by Sunburst de Mexico are owned by Compañía Minera. There is no relationship between Compañía Minera and Mexoro, its officers, directors and affiliates. The following table sets forth those concessions in the Guazapares area that Sunburst de Mexico owns or has the option to purchase:  GUAZAPARES CONCESSIONS OWNED BY SUNBURST DE MEXICO

Effective January 1, 2006, this Mexican Government legislation has converted all of the former exploration concessions in Mexico, which carried a maximum six year life, and exploitive concessions, which had a 25 year life, into general concessions with a 50 year life from the date they were registered with the Mining Registry. The concessions are automatically registered as soon as the concession mining rights are paid and no further paper work is required. These claims are currently in good standing and held by Sunburst de Mexico. There will be no special documents sent to us to reflect this change.  (2) These concessions have been transferred to the Company. However, we must continue to make payments on these concessions in order to retain ownership. The total payments for us to acquire and retain 100% ownership of all eight concessions are as follows: November 30, 2005 - $100,000 (this payment date has been extended  see below), October 31, 2006 - $60,000 (this payment date was extended to February 28, 2007 and then to May 31, 2007 and then to August 31, 2007- see below 5), August 2, 2007 - $140,000 (see below 5), August 2, 2008 - $110,000 and August 2, 2009 - $500,000. These scheduled payments must be made to keep our agreement in good standing. Failure to make the payments would cancel our agreements to acquire these concessions.  (3) These concessions are currently under option agreements. Title to the concessions has not yet been transferred to the Company. The total payments for us to acquire 100% ownership of all three concessions are as follows: January 15, 2006 - $20,000 (paid), January 15, 2007 - $40,000 (this payment was deferred until April 15, 2007 and payment was made on March 26, 2007), January 15, 2008 - $50,000 (this payment was deferred to January 31, 2008 and was paid in April 2008), January 15, 2009 - $50,000 and January 15, 2010 - $500,000. These scheduled payments must be made to keep our option to acquire these concessions in good standing. Failure to make the payments would cancel our options to acquire these concessions.  (4) This concession is currently under an option agreement. Title to the concession has not been transferred to the Company. The total payments for us to acquire 100% ownership of this concession are as follows:  June 25, 2006 - $20,000 (this amount has been paid), June 25, 2007 - $30,000 (this amount has been paid), June 25, 2008 - $40,000 and June 25, 2009 - $250,000. These payments must be made to keep our option to acquire these concessions in good standing. Failure to make the payments would cancel our options to acquire these concessions.  (5) On September 19, 2007, Sunburst de Mexico, Mexoro and MRT entered into an agreement to defer any and all property payments regarding Guazapares, currently owing to MRT and which would otherwise become due by December 31, 2007, until such time as Sunburst de Mexico and Mexoro have sufficient funds to make the payments, in the opinion of the disinterested directors of Mexoro.  History   Old mining records in the public domain indicate that mining operations commenced on this site in the 17th century. Most of the production on this site came from high-grade vein deposits mined by crude underground methods. These records indicate that the main Guazapares breccia veins were discovered in or around 1830. The major period of production was from 1870 to 1900, when there were four silver pan amalgamation mills in operation. Although the deposits contain both gold and silver, the early mills could not recover the gold as it is very fine and occurs along cleavage planes in the pyrite. The mills at the time could only process the oxidized portions of the veins, and the unoxidized, sulfide-bearing material was usually left in the mines as pillars. The principal mine owner died in 1890, after which the mines of Guazapares slowly sank into disrepair and closed by 1900. In 1905, a U.S. company consolidated most of the properties and reopened some of the mine workings. The company ran into financial difficulties during 1907 and work halted. Ramon Valenzuela then acquired the Guazapares Property and operated a mill until 1912. Noranda Exploration, Inc. briefly optioned concessions in the area in the early 1990s. Kennecott Utah Copper Corp. optioned the core concessions in 1993-94 and drilled a few holes at one of the concessions. On Guazapares 4, and on a property adjacent to it, War Eagle Mining Company, Inc. drilled a total of 5,552 meters in 50 holes on three mineralized zones between November 1991 and August 2002.  Geology    23   There are two main deposit types that are considered relevant to the Guazapares Property: epithermal vein and mesothermal vein. These are briefly discussed below.  In an epithermal gold deposit, the gold is deposited within one to two kilometers of the surface and is deposited from hot fluids. The fluids of epithermal systems range between 50 and 200 degrees Celsius with moderate pressures (Panteleyev, 1991-4). These deposits are typically related to volcanism in continental arc settings. Epithermal type mineralized veins are often spatially and genetically related to porphyry systems (Panteleyev, 1991-4). Epithermal gold deposits are formed by two chemically distinct fluids. The first is low sulphidation fluid, a mixture of meteoric water and magmatic fluid that is of nearly neutral pH. Gold is carried in solution in low sulphidation waters and is deposited when the water rises to shallow low pressure levels in the crust and boils. The second fluid, high sulphidation fluid, which is almost totally derived from a magmatic source is deposited when the fluid cools or is mixed with meteoric water. Gold and other metals can originate either from the magma or be leeched from the host rock as the fluids travel though fractures. Low sulphidation fluids typically form mineralized cavity filling quartz veins. High sulphidation fluids often form mineralization that is penetrative into the host rock often observed as disseminated texture. Low sulphidation systems are known for containing economic quantities of silver with some copper, lead, and zinc. Other minerals associated with low sulphidation systems are chalcedony, carbonate, pyrite, sphalerite, and galena. High sulphidation systems often contain economic quantities of gold and copper. Other minerals associated with high sulphidation systems are quartz, alunite, pyrite, and other copper minerals (Panteleyev, 1991-4). Geochemical exploration for these types of deposits results in different chemical anomalies depending on the type of mineralization present. Low sulphidation deposits are higher in zinc and lead, lower in copper, and have a higher ratio of silver to gold. High sulphidation deposits are higher in arsenic and copper and have lower silver to gold ratio.  Mesothermal gold deposits can be hosted in a wide variety of lithologies. These deposits often show relationships with regional scale strike slip faults (Olsen et al., 1994). Analysis of fluid inclusions from samples of quartz veins give average temperatures of more than 250 degrees Celsius. These veins are podiform, sheared, and concordant with enclosing schists of a transitional greenschist-amphibolite grade. Gold mineralization is best associated with faults that show evidence of deformation that is transitional between ductile to brittle and associated with greenschist to amphibolite facies metamorphism (Olsen et al., 1994). Mesothermal gold deposits are found in the proximity of major regional fault and fracture systems and most often hosted in secondary or tertiary structures related to the regional scale structures. The gold is deposited from hydrothermal fluids which originated deep in the earths crust with temperatures of 250 to 400 degrees Celsius. The fault and fracture zones act as permeable conduits for the fluids to migrate. Gold is carried in solution until the fluid reaches a point where either there is a chemical reaction with the country rock or changes in temperature and/or pressure cause the gold to precipitate. The gold and associated metals precipitates out of solution along with quartz vein material. Mesothermal type deposits can be recognized by the fact that the host rocks show the affects of the fault/fracture origins. Structural evidence such as folds in bedding or pinches, swells, and pods in quartz veins is characteristic of ductile deformation and can be often found in at mineralized mesothermal quartz veins. Mesothermal quartz carbonate veins typically include pyrite and arsenopyrite with the gold. Gold can be pure, and be found as free grains or grains intergrown with sulphide minerals. The gold can also occur within the crystal lattice of arsenopyrite or as electrum, a gold mineral containing between 20 to 80 percent silver. Mineralized mesothermal quartz carbonate veins are characterized by iron rich hydrothermal carbonate alteration assemblages which are pervasive with respect to the host rock.  Mineralization  The style of mineralization at the Guazapares Property is characterized by gold and silver bearing veins and vein breccias occurring within and/or at the intersection of numerous north  northwest structures (San Francisco and San Antonio Fault Systems) and west  northwest structures (San Antonio and El Cantilito Fault Systems). These are multi-phase deposits which produced several generations of cross-cutting veins, veinlets, breccias and related hydrothermal alteration. Alteration ranges from peripheral propylitization to argillic alteration to strong to intense silicification, often with adularia development. This mineralization is physically expressed as quartz vein stockworks, silicified hydrothermal breccias, and vuggy, quartz-filled expansion breccias. At many such deposits, such as those nearby at Palmarejo (Gustin, 2004), there are at least two stages of gold-silver mineralization. The first is characterized by pyrite, sphalerite, galena and argentite in structurally controlled quartz vein breccias. There is often a later fine-grained higher-grade gold-silver, base metal-deficient phase cross-cutting the first (Durgin, 2007).  Numerous polymetallic vein showings have been the subject of much of the exploration work at the Guazapares Property.  The San Francisco Area was found to contain mineralized quartz veins, vein breccias, and quartz vein stockwork zones comprising and area of approximately 500 by 700 meters. The mineralized zone trends predominately northwest, with the highest grade mineralization occurring at intersections with the west, northwest, and northeast trending faults. The San Francisco area is characterized by stockwork type mineralization, with silicification being the major alteration.  24    The San Antonio Area consists of two main mineralized veins trending northwest and west-northwest. The mineralization covers an area of 500 by 300 metres and is observed as quartz veins and quartz stockworked veins. These exhibit textures of multiple phases of hydrothermal activity.  The El Cantilito Area is a mineralized zone found related to west and northeast trending structures where high concentrations of gold and silver have been found. The mineralization style is quartz veins, quartz stockwork, and silicification observed to cover a 500 by 350 meter area within the felsic volcanic rocks.  The Montana de Oro Area lies to the north of the Guazapares Property. This showing is characterized by mineralized structures trending north-northeast, where development of mineralized shoots was found to contain high gold concentrations.  Mineral Deposits  Geological mapping and sampling over an area of four square kilometers has outlined numerous mineralized areas within the project area.  According to our VP of Exploration, the Guazapares property consists of a series of sub-vertical, brecciated, quartz-rich zones that outcrop within an area of approximately four square kilometers and have a strike length of over two kilometers. The mineralized areas and identified drilling targets include four main zones: San Antonio, San Francisco, El Cantilito and Montaña de Oro. The mineralization is characterized by silver-gold low-sulphidation veins, locally overprinted by high-level high-grade gold-silver quartz veins. The mineralized areas and veins are structurally-controlled by north-northwest striking faults and west-northwest trending faults that have favored the development of high-grade mineralized shoots.  Mineralization at Guazapares is characterized by gold-silver veins and vein-breccias occurring within and/or at the intersection of numerous north-northwest structures (San Francisco and San Antonio fault systems) and west-northwest structures (San Antonio and El Cantilito fault systems).  On the basis the field evidence, all four mineralized areas have been considered to be prospective in which three of them San Francisco, San Antonio and El Cantilito have been followed up with initial geological mapping, sampling and drilling.  The San Francisco area is characterized by mineralized quartz veins, vein/breccias and quartz veins stockworked zones covering an area of approximately 500 x 700 meters. The mineralized zone trends predominantly northwest developing high-grade mineral concentration within the intersection of the west, northwest and northeast trending faults. The San Francisco area includes mainly stockwork mineralization and silicification, exhibiting small and localized areas of vuggy quartz within the volcanic rocks. Detailed rock chip sampling along these mineralized zones has returned high silver values ranging from trace to 2,160 g/t Ag, where gold values vary from 1.17 to 2.28 g/t Au.  Early mining, by previous owners, was focused mainly on the San Antonio vein domain where high-grade gold mineralization sampling has returned values of 42.6 g/t Au and 1,100 g/t Ag present in underground workings. Two main mineralized veins domain trending northwest and west-northwest have been identified within this targets area. Mineralization comprises an area of 500 x 300 meters and consists of quartz veins and quartz stockworked veins exhibiting multiple pulses of hydrothermal activity. Assay results from rock chip samples have returned gold values registering from trace to 8.76 g/t Au.  The El Cantilito area is a mineralized zone mainly along west and northeast trending structures where high concentrations of gold are common, varying from 1.86 to 8.39 g/t Au and exhibiting silver values from trace to 656 g/t Ag. El Cantilito is characterized by quartz veins, quartz stockwork mineralization and silicification developed in an area of approximately 500 x 350 meters within the hosting volcanic rocks.  The Montaña de Oro area is a newly identified target to the north of the Guazapares project. Montaña de Oro is characterized by mineralized structures trending north-northeast, where development of mineralized rock-shoots containing frequent high gold values (5.39, 7.22, 1.75, 19.7 and 2.5 g/t Au).  Most of Mexoros exploration efforts have been concentrated on the San Antonio and San Francisco vein domains although the vein and breccias textures, structures, alteration and metal association suggest that mineralization areas at Guazapares  25   are of low-sulphidation style. According to our VP of Exploration, these structural and mineralized systems are open towards both the north and south. Detailed field work will continue in all identified targets in conjunction with building road access and drilling platform on selected drilling locations.  The Guazapares property is without known reserves. Our proposed exploration programs are exploratory in nature.  Infrastructure  Guazapares has the infrastructure in place to support a mining operation. It has diesel generated electrical power, water, railroad transportation within 20 kilometers and an all weather road access all year round. There is trained labor for mining available in the area.  Budget  We have estimated that the exploration program on the Guazapares Property, including the recently completed drill program and an amount for a subsequent drilling program, will cost approximately $2.87 million. Of this amount, we spent approximately $672,000 from July 2007 through to the end of December 2007 for phase 1 of exploration. We have budgeted approximately $1.48 million from the total $2.87 million for additional drill program expenditures. See Plan of Operations in the Managements Discussion and Analysis section for further information.  Encino Gordo Property  Location  The Encino Gordo project is located in the Barranca section of Chihuahua State in Mexico, and according to data publicly published by the Mexican Government, it is at the interphase between the two main volcanic groups that form the bulk of the Sierra Madre Occidental. The Encino Gordo Property is 3.2 miles west of the Guazapares Property. The location is 220 kilometers to the southwest of Chihuahua City. The property is accessible by an all weather dirt road along the southwest side of the property.  Claim Status  Sunburst de Mexico owns two concessions (Title 220149 and 220148) and has the option to acquire 100% of the three other properties listed below, subject to a 2.5% NSR and making the scheduled property payments.

(2) Concessions are 100% owned by Sunburst de Mexico with no further payments to be made.  26    (3) The total payments for us to acquire 100% of these concessions from the concession owners are as follows: June 30, 2006 - $10,000 (this amount has been paid), December 31, 2006 - $25,000 (this payment was deferred until March 31, 2007 and payment was made on March 26, 2007), December 31, 2007 - $50,000 ($20,000 of this payment was made on January 3, 2008 and balance was paid on February 29, 2008), December 31, 2008 - $75,000, December 31, 2009 - $125,000 and December 31, 2010 - $200,000. These scheduled payments need to be made to keep our agreement in good standing. Failure to make the payments would cancel our agreements to acquire these concessions.   History  The Encino Gordo Property, covering 1,042 hectares (approximately 2,575 acres), is situated near an old mining district with a lengthy production history, according to public records. Old mining records indicate that mining operations commenced three kilometers east of this site in the 17th century. Most of the production from those mines came from high-grade vein deposits mined by crude underground methods. To the east of Encino Gordo, the main Guazapares breccia veins were discovered in or around 1830. The major period of production was from 1870 to 1900 when there were four silver pan amalgamation mills in operation. Although those deposits contain both gold and silver, the early mills could not recover the gold as it is very fine and occurs along cleavage planes in the pyrite. The mills of the time could only process the oxidized portions of the veins, and the unoxidized, sulfide-bearing material was usually left in the mines as pillars. The principal mine owner of the properties east of Encino Gordo died in 1890, after which the mines of Guazapares slowly sank into disrepair and closed by 1900. In 1905, a U.S. company consolidated most of the properties to the east of Encino Gordo and reopened some of the mine workings. That company ran into financial difficulties during 1907 and work halted. Ramon Valenzuela then acquired the properties to the east of Encino Gordo and operated a five stamp mill until 1912. Noranda Exploration, Inc. briefly optioned concessions in the area in the early 1990s. Kennecott optioned the core concessions east of Encino Gordo in 1993-94 and drilled a few holes in one of the concessions to the east of Encino Gordo. The Encino Gordo property has never been in production.  Mineral Deposits  Blackstone Resources Inc. hired Reliance Geological Services of Vancouver, Canada in 1996 to evaluate the results of a geological and geochemical exploration program on the Encino Gordo Property. The subsequent work revealed results that were judged worthy of a second phase of exploration. Our surface sampling has indicated the presence of mineralized structures, including gold and silver anomalies on the property. Several gold and copper anomalous areas were also identified. The property is at the very early stages of exploration, though, and much more work is needed before any decisions can be made as to the viability of the property.  Structure Empalme  The Empalme vein outcrops northwest of the Elyca structure, inside the Encino Gordo Property and has been mapped for approximately 150 meters. Workings on the breccia-vein consist of two old shafts now filled with water. The host rocks consist of a sequence of volcaniclastic sediments overlain by tuffaceous dacites with moderate silicification and supergene argillic alteration.  Cienega Vein  Our exploration shows that the Cienega vein outcrops at one location along a stream bed within the Encino Gordo Property. It consists of brecciated quartz and contains 2% to 3% disseminated pyrite hosted by brown volcaniclastics.  Arroyo Los Laureles Vein  The vein outcrops in the southeast limit of the San Miguel claim in Arryo Los Laurels. The host rocks consist of intensely fractured volcaniclastic arenites, tuffs and dacites.  The Encino Gordo Property is without known reserves. Our proposed exploration programs are exploratory in nature.  Infrastructure  The Encino Gordo Property is accessible year round by all weather roads. There is no local electricity or water currently available. We will need to supply our own diesel generated electrical power.  27    Budget  We estimate that the total geochemical and geophysical exploration program on the Encino Gordo Property will cost approximately $138,000, through December 2008, and will have the goal of identifying drill targets for a subsequent drilling program. We budgeted $50,000 for mapping and sampling, which was completed in February 2007. We spent $50,000, as budgeted, through the end of February 2007. The balance of the budgeted funds will be spent as directed by our VP of Exploration once he has reviewed all of the initial material on the property and the results of the exploration completed in February 2007. From November 2006 to April 2008 we spent $64,000 on surface exploration. At this time we do not have the necessary working capital to proceed. The geochemical sampling and mapping is preliminary work which will allow the VP of Exploration to have sufficient information available to him to plan an exploration strategy and budget for this property. We have not conducted any exploration on this property other than preliminary sampling and mapping. See Plan of Operations in the Managements Discussion and Analysis section for further information.  Sahauyacan Property  Location  The Sahauyacan Property is located near the Chihuahua-Sonora State border approximately 275 kilometers east-southeast of the city of Chihuahua and 50 kilometers south-southwest of the town of Mycoba in the state of Chihuahua, Mexico. The property is accessible by all weather dirt roads running through the center of the property.  Claim Status  The Company has recently optioned 14 mineral concessions totaling 649 hectares, which old mining records indicate cover an epithermal quartz vein system. The concessions are owned by Minera Emilio and optioned by Sunburst de Mexico. The following table is a summary of the concessions on the Sahauyacan Property:  Concession NameTitle #Surface (Ha)Term of Validity(1)Royalties and PaymentsVeronica Segunda1710838.00009/8/1982  8/8/2032(2)Esperanza Segunda1710004.00005/8/1982  4/8/2032(2)Maria Luisa1706739.600011/6/1982  10/6/2032(2)Carmela1768564.000012/17/1985  12/16/2035(2)Silvia217673212.75496/8/2002  5/8/2052(2)La Chonca218432228.18085/11/2002  4/11/2052(2)La Cumbre21609167.03149/4/2002  8/4/2052(2)La Cumbre II2203495.24987/18/2003  7/17/2053(2)La Cumbre II Fracc.

Effective January 1, 2006, this Mexican Government legislation has converted all of the former exploration concessions in Mexico, which carried a maximum six year life, and exploitive concessions, which had a 25 year life, into general concessions with a 50 year life from the date they were registered with the Mining Registry. The concessions are automatically registered as soon as the concession mining rights are paid and no further paper work is required. These claims are currently in good standing and held by Sunburst de Mexico. There will be no special documents sent to us to reflect this change.  (2) The Company must pay Minera Emilio a total of $282,000 for these concessions. Of this, $10,000 was paid on December 2005 and $20,000 was paid on October 25, 2006. The December 2005 payment was made as good faith payment as we negotiated to acquire the properties. That payment has been applied to the total purchase price. The Company must pay $2,500 per month for twelve months on the 21st day of each month beginning on August 21, 2006. The monthly payments of $2,500 have all been paid for a total $30,000. Beginning on August 21, 2007, the Company must pay $3,500 per month  28   on the 21st of each month for twelve months. The monthly payments of $3,500 have all been paid to February 2008 for a total of 7months and $24,500. We are in default for March 2008 and April 2008 payments. We expect to make these payments in May 2008.  Beginning on August 21, 2008, the Company must pay $5,000 per month on the 21st of each month until the balance of $282,000 is paid (36 months).  (3) This concession was originally included in the Promise to Contract an Option Agreement between Minera Emilio and Jose Emilio Touche Creel on December 5, 2005, whereby Sunburst de Mexico set forth an offer to enter into and execute an exploration and option to purchase an undivided 100% title in and to the mining concessions located in the Sahauyacan Property. This concession was not included in the Exploration and Sale Option Agreement of Mining Concession contract dated June 21, 2006. At the present time, Mexican public records show that this concession has been cancelled; however, there is an official letter issued by the Mexican Mining Director General at that time which notifies that cancellation was revoked. Minera Emilio has the option to reinstate this concession.  (4) The Company must pay the following concession representatives a total of $255,000 for this concession: Leopoldo Rascon Lopez, Sabino Amador Rascon Polanco and Rene Muro Lugo. Each concession representative owns 33.3% of the total Segundo Santo Nino title. The total payments to acquire 100% of this concession are as follows: all payments up to the date of this annual report totaling $55,000 have been paid, May 15, 2008 - $10,000, November 15, 2009 - $20,000, May 15, 2009 - $20,000 and November 15, 2010 - $30,000 and May 15, 2010 - $120,000.  (5) The Company must pay the following payments to Maria Luisa Wong Madrigal to acquire 100% ownership of these concessions:  January 25, 2008 - $33,000 (paid), July 25, 2008 - $33,000, January 25, 2009 - $34,000 and July 25, 2010 - $500,000. These scheduled payments must be made to keep our option to acquire these concessions in good standing. Failure to make the payments would cancel our options to acquire these concessions.  History  The main vein in the area, the Santo Nino vein was the focus of a small scale underground gold mining operation in the late 1800s and early 1900s, with at least three main underground mine access drifts supplying feed to a centrally located mill, which is still present. The mine was closed at the time of the Mexican revolution. The Santo Nino vein system has not been evaluated using modern techniques or explored by drilling.  Geology  Our initial exploration work on the property, as part of due diligence before acquiring the property, indicates that the geology exposed in the project area reveals a complex geologic history. We believe that the basement in the area is composed of dark gray-green massive, fractured and folded phyllitic metasedimentary and metavolcanic rocks in contact with Lower to Middle Cretaceous banded shale and fine grained arenite. Our exploration suggests that these phyllitic rocks are in contact with a Tertiary volcaniclastic sequence that occurs as intercalated fine to coarse grained tuffaceous sediments, volcanic breccias and flows which range in composition from andesite to rhyolite. Our exploration suggests that the entire sequence has been locally crosscut by at least two intrusive units of diorite to rhyolite composition possibly represent synvolcanic hypabyssal intrusions. The Tertiary volcanic sequence is the main host to the gold/silver quartz vein system present in the project area.  Mineral Deposit  A surface geological mapping and sampling crew evaluated the property from September 2006 through December 2006. Mapping on the property was completed at a scale of 1:5,000 with individual veins being mapped at a scale of 1:1,000. To date, a total of 300 samples have been taken from the property, including 101 rock chip and channel samples, 41 stream sediment samples and 158 soil samples. The underground workings were evaluated for safe entry and the mine has been deemed unsafe to open. A limited part of the mine was opened and bulk samples were taken. The Sahauyacan Property is without known reserves. Our proposed exploration program is exploratory in nature.  Santo Nino Vein  Our initial mapping indicates the Santo Nino vein consists of milky quartz and crackle breccia accompanied by iron oxides and veinletts of crustiform, banded and chalcedonic quartz which is suggestive of an epithermal origin. Our sampling of the rocks shows that mineralization presently recognized within the vein consists of chalcopyrite, malachite, azurite, pyrite and abundant iron oxides with manganese oxides. The predominant alteration adjacent to the vein is moderate to strong argillic alteration with local quartz and sericite which forms a halo to the vein which is locally up to 50 meters wide. Further from the vein this moderate to strong argillic zone is transitional to a zone of weak argillic alteration accompanied by supergene oxidation, and propylitic alteration. This weak argillic alteration zone is more than 200 meters wide. Our initial exploration has shown that the vein is locally offset along at least one left lateral fault (in the Mina Cobriza area).  Our initial exploration shows that a second quartz vein parallel to and west of the Santo Nino vein has been mapped (Santo Nino Segundo vein). The northern termination of the Santo Nino vein appears to represent a fault offset (left lateral fault)  29   possibly offsetting the mineralizing system 200 meters to the west. Here the wide weak argillic alteration zone (hangingwall to the vein system) is present and continues to the north-northwest for more than 500 meters to Sahuayacancito.  La Cumbre:  The La Cumbre area covers the local hill top located approximately 500 meters east of the Santo Nino vein. Cominco (now Teck Cominco Limited), drilled at least three holes in this area in the mid 1990s. Drill results have not been obtained from this work.  Our initial work in the area shows that the stratigraphy in the La Cumbre area consists of tertiary volcanics composed of porphyritic andesitic flows intercalated with fine to coarse volcaniclastic sediments overlain by rhyolite tuffs and flows. Tectonic breccias and stockwork zones are accompanied by veins and veinletts of chalcedonic quartz with iron oxides (hematite), manganese and very fine pyrite. Four brecciated structures have been identified to date in our preliminary exploration. Alteration consists of pervasive silicification with weak to moderate massive chalcedonic quartz in the matrix of the breccias, accompanied by a weak argillic alteration of the wall rock. Numerous old surface trenches are present in this area and will be the subject of future sampling and mapping.  Drilling program  Reconnaissance and detailed mapping (1:1,000) programs in the Sahuayacan project have identified four significant drilling targets: Santo Niño, La Cumbre, Cerro Cacho and Santa Teresa.  To date a total of approximately 2,000 meters have been drilled in 13 diamond drillholes. Eight holes were drilled in the Santo Niño vein-structure (SDH-1, through SDH-4 and SDH-7 through SDH-10), two diamond drillholes (SDH-5 and SDH-6) were drilled in La Cumbre mineralized area and two holes (SDH-11 and SDH-12) on the Santa Theresa vein.  SDH-1 through SDH-4 and SDH-7 through SDH-10 were collared along the Santo Niño mineralized vein. Drillhole SDH-1 intersected two zones of gold mineralization over the 165.05 meters drilled in this hole, including 7.50 meters with 2.56 g/t Au and 11.00 meters with 2.24 g/t Au including 8.00 meters with 2.98 g/t Au.

The results from drillholes SDH-3 and SDH-4 showed gold anomalies varying from 0.01 to 0.02 g/t. Geological and structural mapping survey along the Santo Niño vein has identified a north-east structure that is displacing the mineralized zone. Current field investigations are aimed to define in more detail the structural setting on this part of the mineralized vein-structure.  Drillholes SDH-5 and SDH-6 were collared in the La Cumbre zone. The two holes intersected mineralization from surface to 175 metres. Only the SDH-5 intersected several two meters wide intercepts with gold mineralization. Our VP Exploration  30   believes that the gold in these zones is free gold and is contained in the fractures in the oxides. As the drilling consumes massive quantities of water, we believe the free gold has been washed away from the core. As a result, we plan to re-drill the La Cumbre zone using reverse circulation drilling to ensure all the particles are captured while drilling. No assurance, though, may be given that any gold values will be found when it is redrilled using reverse circulation drilling.  The final area tested at Sahauyacan was the Santa Theresa target, where two drillholes (SDH-11 and SDH-12) were completed. SDH-12 has intersected a mineralized zone, consisting of 7.5 meters with 56.01 g/t Au and 283.22 g/t Ag.

A summary of the assay results of the mineralized zones intersected is provided in Plan of Operations in the Managements Discussion and Analysis section.  Infrastructure  The Sahauyacan Property is accessible year round by all weather roads. There is no local electricity or water currently available. We will need to supply our own diesel generated electrical power.  Budget  We spent $557,000 from January 2007 to February 2008, on an initial geochemical and geophysical exploration program on the Sahauyacan Property.  The goal of the exploration was to identify drill targets for a subsequent drilling program. We have one geologist doing preliminary sampling and mapping of this property based on the recommendation of our VP of Exploration. We have finished our 13 hole drill program on the property, which cost approximately $365,000 and $92,000 for the sample analysis and lab. See Plan of Operations in the Managements Discussion and Analysis section for further information.  Employees  The Company currently has 28 persons working for Sunburst de Mexico in Mexico, including four geologists, field staff and administrative personnel. All of these persons are provided to Sunburst de Mexico under third party contract, either directly or via a personnel service agency. Our VP of Exploration began work on March 1, 2007. The VP of Exploration is a full time position with a salary of $110,000 per year plus incentive stock options, stock awards, living allowance and benefits. The job entails spending time in the field directing the exploration projects on our four properties. Other than the VP of Exploration, all mineral exploration and operations are contracted out to third parties. In the event that our exploration projects are successful and warrant putting any of our properties into production, all such operations would be contracted out to third parties. Also, we rely on members of management to handle all matters related to business development and business operations.  ITEM 1A. RISK FACTORS  Not Applicable.  ITEM 2.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION  Special Note of Caution Regarding Forward Looking Statements  Certain statements in this Form 10-K/A, including statements in the following discussion which are not statements of historical fact, are what are known as "forward looking statements", which are basically statements about the future. For that reason, these statements involve risk and uncertainty since no one can accurately predict the future. Words such as "plans," "intends," "will," "hopes," "seeks," "anticipates," "expects "and the like often identify such forward looking statements, but are not the only indication that a statement is a forward looking statement. Such forward looking statements include statements concerning our plans and objectives with respect to the present and future operations of the Company, and statements which express or imply that such present and future operations will or may produce revenues, income or profits. Numerous factors and future events could cause the Company to change such plans and objectives or fail to successfully implement such plans or achieve such objectives, or cause such present and future operations to fail to produce revenues, income or profits. Therefore, the reader is advised that the following discussion should be considered in light of the discussion of risks and other factors contained in this report on Form 10-K/A and in the Company's other filings with the SEC. No statements contained in the following discussion should be construed as a guarantee or assurance of future performance or future results.  Overview  We are a start-up exploration stage company and have not yet generated or realized any revenues from our exploration projects, which commenced on May 1, 2004. As of February 29, 2008 we had $12,947 in our bank account and do not have sufficient cash to maintain our operations after June 2008. Currently, officers of the company are providing the necessary working capital to maintain our current operations. The funds coming from the officers are interest free loans with no terms of repayment and are unsecured. The officers are committed to providing the necessary working capital for the company to keep its operations going until June 2008 but they are not contractually obligated to do so. It is unlikely that the officers of the Company can contribute additional working capital after June 2008. If no additional capital is raised prior to the end of June 2008, we will most likely have to cease operations. Furthermore, if our exploration is successful, we will need to raise additional funds to meet our needs for additional exploration and/or production.  Our continued existence and plans for future growth depend on our ability to obtain the additional capital necessary to operate either through the generation of revenue or the issuance of additional debt or equity. While we believe that we have raised sufficient funds in our recent private placement offering and loans from our officers to allow us to continue in business until July 2008, we may not be able to continue in business beyond that date unless we obtain additional capital. We have  33   not generated any revenues, and no revenues are anticipated unless and until mineralized material is discovered on the properties in which we have an interest.  On May 5, 2008, we signed a letter of intent (LOI) to enter into a strategic alliance with Paramount Gold and Silver Corp. (Paramount). The agreement calls for Paramount to invest a minimum of $4 million and maximum of $6 million into the Company, fixed at a price of $0.50 per unit by June 23, 2008. The LOI contemplates that Paramount will provide an immediate cash infusion into Mexoro in the amount of $500,000 in the form of a secured convertible debenture bearing interest at a rate of 8% per annum for a term of one year.   On May 9, 2008, we issued a secured convertible debenture (the Debenture) with a one-year term.  The Debenture is in a principal amount of $500,000 and carries a per annum interest rate of 8%.  In connection with the issuance of the Debenture, we entered into a Security Agreement with the Debenture holder that secured our assets until there has been full compliance with the terms of the Debenture.  The Debenture holder may convert all or a portion of the principal amount of the Debenture into units consisting of one share of our common stock and half a warrant to purchase one share of our common stock.  Subject to certain adjustments upon the occurrence of various capital reorganizations and other events, the units are convertible at $0.50 per unit for a total of up to 1,000,000 shares of common stock and up to 500,000 warrants to purchase shares of common stock (the Warrants).  The Warrants have a term of four years from the date that the Debenture holder converts the Debenture or the portion of the Debenture covering those warrants.  A holder of the Warrants may exercise those Warrants at $0.75 (subject to adjustments upon the occurrence of certain events like stock splits).  For the 12 month period from May 2008 to April 2009, we may need to raise additional capital to maintain operations. We will need a minimum of $550,000 for taxes and property payments and an additional $1,400,000 for general and administrative costs. This does not include any capital to execute our exploration programs as detailed below. The following table shows our contractual property payments that are due until April 2009:   NameDatePayment TypeUSDEncino Gordo PropertyDecember 31, 2008Property payment$75,000San FranciscoJune 2008Property payment$40,000Sahauyacan PropertyJuly 2008Property payment$33,000Sahauyacan PropertyAugust 2008Property payments$180,000Guazapares Property1August 31, 2008Property payment$110,000Cieneguita Property2May 2008Property payment$60,000San AntonioJanuary 2009Property payment$50,000  1All Guazapares payments due by December 31, 2007 have been deferred, until in the opinion of the directors of Mexoro, Sunburst de Mexico and Mexoro have sufficient funds to make the payments. This includes deferred payments of $60,000 in August 2006 and $140,000 in August 2007.  2The Cieneguita property payment of $120,000 was due in May 2008, of which, Mexoro paid $60,000. The balance of $60,000 was due and outstanding at the date of this report.  Additionally, if our exploration during that time period is successful, we may need to raise additional capital to fund those exploration programs. At this time, we cannot assess with any accuracy our total capital needs to fund an expanded exploration program beyond our basic program. As part of our agreement with Paramount Gold and Silver we are expecting a capital infusion between $4 and $6 million prior to June 23, 2008.  No assurance can be given, though, that these funds will be received by us. We do not have any additional sources of additional capital to fund our operations beyond June 2008 if the funds from Paramount are not received. We also believe that we will not generate any revenues that would allow us to continue operations. If we are unable to raise additional capital through debt or equity beyond June 2008, it is most likely that  34   we would need to cease operations and forfeit our properties as we would be unable to make the necessary property payments.  Plan of Operations  Summary  Our business plan is to proceed with the exploration of our Mexican mineral properties to determine whether they contain commercially exploitable reserves of gold, silver or other metals. Currently, we do not have sufficient capital to fund our current exploration plans and meet our monthly general and administrative costs. Our officers have committed to lend additional capital to Mexoro pursuant to a non-interest bearing unsecured loan with no terms of repayment. The officers are under no contractual obligation to provide these funds. The funds should be sufficient to enable the Company to operate until the end of June 2008. After that time, we will neither have sufficient funds to continue our exploration plans nor funds for general administrative expenses. As a minimum, we will need to raise additional working capital to maintain basic operations. We would plan to raise those funds through the sale of equity or debt. At this time we do not have any sources to raise additional capital for the company and no assurance may be given that we will be able to find sources to raise additional capital. Failure to raise any additional capital would most likely require us to cease operations and abandon all of our exploration properties.  In the event that our exploration program finds exploration targets that warrant additional exploration work, including exploration by drilling, we will not have enough cash available to fund an expanded exploration program. If we decide to expand our exploration program, we would need to raise additional capital to meet these needs. We currently do not have any sources of additional capital available to us and we may not have any in the future. The failure to raise additional capital would severely curtail our ability to conduct any additional exploration work that might be warranted because of the results of our current exploration program.  We are not involved in any research and development on our exploration properties. We have no known reserves on the Cieneguita Property, but in anticipation of favorable results, we had planned to put the property into production, subject to the availability of funding and some additional exploration currently being completed. In anticipation of putting the property into production, we purchased approximately $250,000 worth of new and used mining equipment to be used for heap leach production. We had contemplated putting the Cieneguita Property in production during 2008 but recent positive exploration results have put the production schedule on hold. The mineralized material that has been defined by the extensive drilling appears to suggest that the mineralized material is far larger than originally contemplated.  Therefore, Management wants to ensure, based on the new exploration results, that the mine design contemplated will be suitable for the expanded size of the mineralized material. We also anticipate building a processing plant in the city of Chihuahua and we have the necessary permits in place to construct such a plant.  As we have purchased milling equipment and if we do not find sufficient ore reserves on the Cieneguita Property, we may lose all of our capital investment. In that event, we would try to re-sell the equipment we purchase, but no assurances can be given that we would be able to sell the equipment at a price to recover close to our original investment, or at all.  In the event that we did discover a mineral deposit on one of our properties other than the Cieneguita Property, of which there is no guarantee, we would need to expend substantial amounts of capital to put any of our properties into production, if so warranted. The amount of such expenditures is indeterminable at this time as our exploration program has not advanced far enough to provide us with results to determine this information.  Such expenditures are dependent upon the size of the mineralized body, the grade of the mineralization and the type of mining that is required to extract any minerals that may be found. Regardless, we do not have enough capital available to us to make any such expenditure that would be required to put any mineral property into production, and we therefore would have to raise the additional capital or, if possible, enter into a joint venture for the production phase. If we were to form a joint venture, we cannot assess what our final position in the project would be. We do not have any sources of capital available to us at this time to fund such a project if one should be discovered.  We hired our VP of Exploration on March 1, 2007. We also hired an office administrator for our office in Chihuahua. We hired one geologist at the end of August 2006, another geologist in January 2007 and two more geologists in August 2007 to work on our exploration programs. We do not expect any significant change in additional contractors to conduct exploration over the next 12 months. Other than the VP of Exploration and our geologists, all of the employees we hire are contracted from third parties specializing in providing employees for Mexican companies. In using third party contractors, we minimize our  35   exposure to Mexican employment law, and all liabilities are undertaken by the third party contractors providing the services. We pay a flat rate to the third parties for their services.  In the event that we should find a mineable reserve, it is managements intention to contract the mining and milling of any ore reserves out to third parties. If we put the Cieneguita Property into production, we anticipate hiring one mine manager to oversee the work done by the third party contractors. We do not have any known reserves at this time.  Exploration Projects  Current Status  Sahuayacan  Mexoro has completed a diamond drilling program of 13 holes comprising 2,027.35 meters. Nine of the 13 holes were directed to test the Santo Niño vein, two drillholes were collared on the La Cumbre target and two more were drilled on the south of the property to test the Santa Teresa target. Of the 13 drillholes only three have intersected economically attractive mineralization. The mineralized intercepts are as follows:

A detailed report with the most recent drilling results has been completed. All data and field information collected is being evaluated and a second phase exploration and drilling campaign is being planned on selected targets. A second phase drilling program will be aimed to define the potential volume and grade of the mineralized system at Sahuayacan, primarily focusing on the Santa Teresa and La Cumbre targets which may represent a mineralization system developed along a caldera margin. Additional targets have been identified along the circular feature that seems control the emplacement of alteration and mineralization zones on the Sahuayacan Project.  Guazapares  The first drilling program in the Guazapares project has been completed with 19 drill holes totaling 2,670 meters. The most recent drilling results are from 13 completed holes drilled at the San Francisco Este, San Francisco Centro and El Cantilito, three of the main targets identified in the project. All drill holes in the San Francisco Centro and El Cantilito intersected long intervals of gold and silver mineralization. Intersections are shown in true width.  The drilling commenced on the San Antonio area, where three diamond holes (GU-01, GU-02, and GU-03) have been drilled for 452.85 meters. All three holes intersected mineralization at a depth of approximately 100 meters. Surface and underground sampling from San Antonio indicates the mineralization extends from surface to a depth of at lease 135 meters with a width varying from 1.2 meters to 12 meters in thickness. The mineralized structure has a strike length of 800 meters and is open to the northwest and southeast as well as to depth.  The GU-01, GU-02 and GU-03 holes have been focused on extending zones of high-grade mineralization encountered in the San Antonio adit where a new gold zone in the underground samples returned grades of 37 g/t gold and 1,000 g/t silver over two meters. The highest grades occurred within vein-breccias, quartz veins and quartz stockworked veins exhibiting multiple pulses of hydrothermal activity. Analysis of the mineralization and alteration assemblages, structural setting and geochemistry of the San Antonio target area indicates that the high gold values tend to cluster in two main mineralization styles:  1.Mineralized rock-shoots developed along the extensive San Antonio vein system.2.Large and structurally controlled breccia bodies or structural zones developed in the intersections of mainly NW and NE trending faults and structures.   36   San Francisco Este Target  The San Francisco Este target is characterized by mineralized veins/breccias, quartz veins stockworked zones. The mineralized and altered zone on this target trends predominantly northwest. Drillholes GU-04 to GU-07 and GU-17 to GU-18 were designed to test the silver (± gold) mineralization identified on surface. GU-04 intersected 9.55 meters with 2.17 g/t Au Eq from surface down to 10 meters depth. Drillhole GU-08 encountered a mineralized interval of 5.20 meters with 1.68 g/t Au Eq. These intervals complement previous results for the surface sampling where we reported silver values up to 2,160 g/t Ag. Drillholes GU-05, GU-06 and GU-07 reported only gold and silver anomalies and did not intersect economic mineralization. Assay results from GU-17 to GU-19 are still pending. Results from the mineral zone at San Francisco Este are summarized below:  Drillhole GU-04  SampleFromToWidthTrueAuAgID(m)(m)(m)Width(g/t)(g/t)2549801.51.51.05750.023104254991.52.510.7050.02929.9255002.53.651.150.810750.046128255013.654.951.30.91650.15679.1255024.956.451.51.05750.39137255036.457.951.51.05750.09361.3255047.959.451.51.05750.04915.9255059.4510.551.10.77550.05647.22550610.5512.051.51.05750.1483872550712.0513.551.51.05750.231032552935.536.71.20.850.02665.5   San Francisco Centro Target  The San Francisco Centro target is characterized by quartz veins, veins/breccias and quartz veins stockworked areas exhibiting multiple pulses of hydrothermal activity. Mineralization in San Francisco Este tends to cluster in mineralized shoots developed primarily in the intersection of main structures. Drillholes GU-08 to GU-13 were planned to test the east-west mineralized structure identified during the mapping and sampling process in the central part of the concessions. All drillholes intersected mineralization from surface down to 100 meters depth. Drillhole GU-10 intersected 13.75 meters with 2.75 g/t AU Eq. and 22.98 meters with 2.80 g/t Au Eq. from 8.15 meters down to 85 meters depth. Drillhole GU-13 intercepted 9.0 meters with 3.63 g/t Au Eq. and 4.50 meters with 1.56 g/t Au Eq.

Cieneguita  The phase I exploration program at Cieneguita carried out from November 2006 to February 2007 was initially focused on a systematic geological mapping (1:1,000) and sampling of roadcut and outcrop exposures on the property. This program outlined the main mineralization zone which has been traced in outcrops approximately 800 meters along strike. In addition three new high-grade gold areas were identified beyond the known limits of mineralization.  According to our VP of Exploration, the results from the mapping and sampling campaign provided evidence that the potential for the discovery of new areas with gold grades still remains open as shown by the discovery of the Pit 1 South, Central and Pit 2 North areas.  The results from the mapping and sampling campaign outlined two main high-grade gold mineralization areas which are providing additional evidence to increase the known mineralized zone of the Cieneguita system to the NE. Analysis of the alteration, structural setting and geochemistry of the northeast part of the Pit 1 area indicates that there is potential for a structurally controlled body to the northeast of the known PIT 1 area. Assay results have been received for samples from roadcuts and outcrop exposures on the Cieneguita Property. The values ranged from trace to 31.6 g/t Au taken from several two meter channel sample located 75 meters to the NE of the known PIT 1 area. This high-grade gold sample is part of the  42   NE PIT1 area, a 20 meters exposure averaging 5.43 g/t Au. The high-grade gold mineralization encountered at the NE PIT 1 area is part of the same structural trend identified in the PIT 1 area where gold values ranged from trace to 29 g/t Au.  Gold mineralization was also found at the S PIT 2 area, 100 meters to the south of the known PIT 2 area. Sampling on the mineralized area has returned values varying from 1.18 to 3.2 g/t Au.

A total of 18 diamond core holes have been drilled (CI-01 to CI-18) for 3,606.91 core meters since drilling began at Cieneguita early December 2007. All drill holes from this first phase drilling program have been focused on extending zones of high-grade gold mineralization identified by previous drilling programs (Glamis drilling program, 1994-1996). Drill hole CI-4 and CI-11 failed to intersect any economical mineralization.

Gold mineralization at Cieneguita occurs mainly as disseminated and minor proportion structurally-controlled. Mineralization is hosted by breccias and tuffs varying in composition from rhyolite to dacite. The main mineralized and altered zones have been developed to the northwest (PIT-1 area) and southeast (PIT-2 area). These mineralized zones consist mainly of acid-sulphate alteration, including quartz-alunite assemblages exhibiting small and localized areas with residual or vuggy silica. Cieneguita is interpreted to represent a high-sulphidation gold-silver system.  Drilling results have demonstrated the extension of the Cieneguita mineralized system at depth down at least to 250 meters where mineralization is mainly hosted by sulphides. The mineralization zone is still open to the south and to depth. Drilling program continues and a second stage drilling program has been proposed to define the complete mineralization system and provide a NI 43-101 resource estimation.  Encino Gordo  During this year reconnaissance program we carried out a detailed and property scale mapping and sampling program outlining numerous gold, silver and gold-copper coincident geochemical anomalies. The stage I of the exploration program was undertaken in an effort to define the style and characteristics of the mineralization areas indicated by the geochemical anomalies. Within this stage several gold and sulphide mineralization areas including pyrite and chalcopyrite have been identified within an over 500 meters stockwork area and fault-veins structure.  All information and field evidence gathered during the mapping and sampling process are suggesting the presence of porphyry style alteration and mineralization characterized by the presence a concentric alteration patterns (potassic  44   alteration grading outward to quartz-sericite and propylitic alteration), coincident Cu, Au and Mo geochemical anomalies and a multiple-event of veining. No assurance can be given, though, that we will find such a deposit, if at all.  The stage II of the exploration program aimed to detail and characterize all identified alteration and mineralization areas and define and prioritize drilling sites is underway and is expected to be completed by May 2008.  Exploration Projects  Potential and Next Exploration Stage  Our exploration team will aggressively pursue as a high priority the following:  1.Advance all projects to the next exploration stage2.Exploring and try to increment the known resources at the Cieneguita advanced project  3.Design, implement and manage a strong new targets generation and identification of advanced projects program aimed to expand our portfolio.  The following exploration program has been planned for each of the projects:  Sahuayacan  Surface mapping and drilling results are suggesting that the high gold values tend to cluster at certain areas along the Santo Niño and the Santa Teresa vein structures with intervening areas of low gold grades. A more disseminated deposit seems to be present at the La Cumbre area. The cluster of gold values indicate the development of mineralized rock shoots within the extensive Sahuayacan system as evidenced by the intercepts from the SDH-1 in the Santo Niño vein and the SDH-12 along the Santa Teresa vein.  All evidence is suggesting that the mineralization is controlled by a circular feature that may represent a caldera margin running from the Santa Teresa target up to north to the La Cumbre target. This evidence is open up the potential to further extend the mineralization found at Santa Teresa and La Cumbre targets further north.  Next exploration stage will include mapping and sampling along the circular feature trying to define additional mineralization areas and drilling targets.  The figure below shows the different geological elements encountered in the Sahuayacan system and is also exhibiting the relationship between the Santo Niño, La Cumbre and Santa Teresa target areas.   45   [mexoro_amendment10ka2008003.jpg]   46


[mexoro_amendment10ka2008004.jpg]  The above figure illustrates the La Cumbre target and the circular features controlling development of alteration and mineralization at the Sahuayacan Project. La Cumbre and Santa Teresa are both spatially associated with the circular features that may represent the emplacement of a caldera-related Au-Ag hydrothermal system.  If management decides to continue drilling, we will need to raise additional funding through the sale of debt or equity because we do not have sufficient capital to continue such an exploration program. Additional drilling would cost a significant amount of money and there is no assurance that we would be able to raise such additional amounts of money. We have not identified any additional sources of funding to implement such a program  Total budgeted costs for exploration on the Sahuaycan Property for 2008 is $763,000  The Sahuayacan Property is without known reserves. Our proposed programs are exploratory in nature.      47


Guazapares  The mineralization systems encountered in the Guazapares project are essentially of two types: a silver-dominated system at San Francisco Este, San Francisco Centro, and El Cantilito which exhibits localized areas of high-grade gold mineralization; whereas at San Antonio the system is dominated by gold mineralization. Surface mapping and drilling results are suggesting that the high-grade mineralization tends to cluster at certain areas along the mineralized veins with intervening areas of low-grade mineralization. The cluster of high-grade mineralization is suggesting the development of mineralized rock-shoots as evidenced by the intercepts from drillholes GU-04 and from GU-08 to GU-16.  The present drilling results are providing the evidence to highlight the great potential of several areas in the Guazapares project. Main potential targets are shown in the figure below.  1.Drilling results on the San Francisco Este target are opening the potential to explore further northwest along the same structure.2.Drillholes GU-12 and GU-13 at are suggesting the development of high-grade mineralized rock-shoots along structures inflections and have opened up the exploration potential to the west and northwest.  3.Drilling results at El Cantilito (GU-16) have opened up the exploration potential to the west of the system which is a covered terrain. Drillhole GU-15 is also opening potential to the west along the El Cantilito mineralized system and since GU-15 was stopped in mineralization at 169 meters depth the exploration potential is still open at depth.4.All mineralized system and targets are suggesting the potential to explore where all system intersects each other creating the right setting to develop attractive mineralization zones.  [mexoro_amendment10ka2008005.jpg]   48   Diamond drilling of the Guazapares Project encountered mineralization in most of the drillholes. The highest grades occurred within vein-breccias, quartz veins and quartz stockworked veins exhibiting multiple pulses of hydrothermal activity.  Analysis of the mineralization and alteration assemblages, structural setting and geochemistry of the project area indicates that the high gold values are spatially associated to a rhyolite-dacite dome and tend to cluster in two main mineralization styles:  · Mineralized-shoots developed along the extensive San Antonio vein system. · Large and structurally controlled breccia bodies or structural zones developed in the intersections of mainly NW and NE trending faults and structures.  [mexoro_amendment10ka2008006.jpg]  The mineralized rock-shoots still remain open in all directions highlighting the potential for gold mineralization beneath covered areas on project area, though no assurance may be given.  Drilling continues to explore newly identified altered and mineralized areas and extending the mineralized trends and mineralized rock-shoots remaining with open potential in Guazapares.  If management decides to continue drilling, we will need to raise additional funding through the sale of debt or equity because we do not have sufficient capital to continue such an exploration program. Additional drilling would cost a significant amount of money and there is no assurance that we would be able to raise such additional amounts of money. We have not identified any additional sources of funding to implement such a program.  Total funds budget for exploration of the Guazapares project is $1,820,000.  The Guazapares Property is without known reserves. Our proposed programs are exploratory in nature.  49    Cieneguita  The recent exploration activities in Cieneguita have provided with results to highlight the potential of this project. Mapping and sampling process around Cieneguita has identified two new areas of mineralization 500 meters to south of the current known mineralized zones. These two areas are exhibiting same size, characteristics, and intensity of alteration-mineralization that the one encountered on Cieneguita. Detailing mapping and sampling is currently underway.  Leaching tests on oxide and mixed mineralized rock has returned a recovery above 90%, whereas the recovery in the sulphide mineralized rocks is showing recoveries varying from 70% to 75 % in a leaching process lasting 25 to 30 days. Leaching tests combined with the assay results from drilling and the new areas found 500 meters away from Cieneguita are providing the possibility to increase known zones and to make of the Cieneguita deposit an attractive property in the region. No assurance, though, may be given that we will be able to identify an economic ore body at this property. Considering latest results and findings the proposed work program for Cieneguita will include:  · Current drilling program will be extended from 4,000 meters to 6,000 meters · Leaching test to the sulfide encountered at depth by current drilling program · Detailed mapping and sampling of the two new areas identified within our property 500 meters away from Cieneguita.  If management decides to continue drilling, we will need to raise additional funding through the sale of debt or equity because we do not have sufficient capital to continue such an exploration program. Additional drilling would cost a significant amount of money and there is no assurance that we would be able to raise such additional amounts of money. We have not identified any additional sources of funding to implement such a program. If we can not obtain additional financing, we could seek a joint venture partner if the drilling results warranted it. We do not have any joint venture partners at this time and can give no assurance that we will be able to find one if the Cieneguita Property warranted such a joint venture.  The total budget for exploration on the Cieneguita Property is $2,050,000.  The Cieneguita Property is without known reserves. Our proposed programs are exploratory in nature.  Encino Gordo  We carried out a detailed and property scale mapping and sampling program on the Encino Gordo project outlining a porphyry-style mineralization exhibiting numerous gold, silver and gold-copper coincident geochemical anomalies. We have identified two drilling targets in the project area; however in order to define the system better, we have planned a geophysical survey (IP and magnetics) to know the potential of the near-mesothermal (porphyry-style) system present at the Encino Gordo property before the drilling program.  50   [mexoro_amendment10ka2008007.jpg]  The above figure illustrates coincident Cu and Au geochemical anomalies on the Encino Gordo Property which are spatially associated to a potassic alteration core resembling the classical geochemical-alteration signature of the porphyry systems.  Management and our VP of Exploration will review the information provided by phase 1 of the exploration plan and determine whether a drill program is recommended. If a drill program is recommended, and we have received our permits that have been applied for in advance, we do not have sufficient information at this time to estimate what the drill program would entail. We need extensive information to determine the number of drill holes to drill, where they would be located and to what depth they would be drilled. This information will be provided by phase 1 of the exploration plan.  Total exploration budget for the Encino Gordo property is $740,000.  The Encino Gordo Property is without known reserves. Our proposed programs are exploratory in nature.  Target Generation and Growth Strategy  A fundamental component of our strategy is to advance to the drilling stage all of our properties and implement a strong generative and property acquisition program through a well establish financial process and a proper funding consistency.  The proposed generative program will be contemplating four main directions:  1.A new targets generation program that will create a pipeline of quality properties providing a steady stream of new prospect and/or projects for the company to explore, farm-out and/or joint venture out.2.A property acquisition program aimed to identify and acquire at low cost (whenever possible) early- to mid-stage properties on selected locations along the main gold-silver belts in Mexico.  3.Focus on small- to medium-size gold-silver deposits (minimum deposits containing 250,000 oz of Au Eq.)  51    4.The new targets generation and property acquisition program will be initially focused on the Sierra Madre belt and Central Mexico. It will be extended further south in Mexico and other countries if conditions and projects potential warranted.  The proposed exploration program is to be undertaken by the Mexoros exploration team using in-house knowledge in combination for support and guidance of high-quality consultant with expertise in the region. The new targets generation program is aimed to feed our project pipeline at two drill and/or near-to-drill-stage projects per year.  Phase I - Target Generation  Objectives  · Identify two to four target areas (approx. 20 x 30 kilometers) which have potential to host small- to medium-size gold and/or gold-silver deposits. · Identify one or two specific opportunities with close to drill ready targets. For example, identify old workings or existing mines with good upside potential. · Time frame: six months.  Key Steps and Exploration Tools  After initial trip to evaluate gold and gold-silver deposits potential it has become more evident that the acquisition and evaluation of more detailed geological maps and geochemistry with field follow-up is critically important to identify new areas of potential. Careful and selective use of such data may be the most immediate and cost-effective way to focus exploration efforts toward prospective gold-silver areas.  Key steps will include mainly the following activities, among other considerations:  · Acquire geological maps 1:250,000 and 1:50,000 (from SGM) · Generate geological and mineral occurrences base maps. · Identify key host rocks. · Complete structural interpretation from known geology, TM imagery, and geophysical data (if available). · Integrate mineral occurrences, alteration, lithology and structures. · Complete initial targeting using the above compilation. · Select and prioritize targets.   Results of Operations  Year ended February 29, 2008 compared to the year ended February 28, 2007.  In this discussion of Mexoros results of operations and financial condition, amounts, other than per-share amounts, have been rounded to the nearest thousand dollars.  Critical Accounting Estimates  The preparation of the Companys financial statements requires management to make various judgments with respect to estimates and assumptions. On an ongoing basis, management regularly reevaluates its estimates and assumptions; however actual amounts could differ from those based on such estimates and assumptions.  The Company has made certain accounting estimates that have a material bearing on the financial statements. The principal of such estimates are:  Income Tax Valuation Allowance  The Company has a potential $4,305,400 deferred income tax asset based on the difference in timing of certain deductions for income tax and accounting purposes. The ability of the Company to ultimately derive a benefit from the deferred tax asset  52   depends on the existence of sufficient taxable income of the appropriate character within the carry forward period available under the tax law.  References in the discussion below to 2008 are to our current fiscal year ended February 29, 2008, while references to 2007 are to our fiscal year ended February 28, 2007.  Revenues  We did not earn revenues during 2008 or 2007 because we did not have commercial production of any of our properties. We do not anticipate earning revenues until such time as we have entered into commercial production of our mineral properties, if ever. We are presently in the exploration stage of our business. We can provide no assurance that we will discover commercially exploitable levels of mineral resources on our properties or, if such resources are discovered, that we will enter into commercial production of our mineral properties. Interest income is recorded under Other Income in the Statement of Operations in the financial statements.  Operating Costs  We did not incur any operating costs during the years ended 2008 and 2007 due to the fact that we did not achieve production from exploration activities during either year.  Expenses  Our expenses increased to $8,040,328 for the year ended February 29, 2008 compared to $5,106,389 for the year ended February 28, 2007, representing an increase of $2,934,000.  In 2008, we incurred higher general and administrative expenses, exploration expenses and write off of property costs, which resulted in increase of expenses.  The increase in 2008 is attributable to $816,000 spent on investor relation activities compared with $111,000 in 2007 to raise additional funds for exploration activities and higher advertising and promotion costs of $159,000 in 2008 compared to $nil in 2007.  Our exploration expenses increased to $2,680,680 in 2008 compared with $1,089,498 in 2007 as a result of the increased activity of the Company as it advanced its business plan.  For the year ended February 29, 2008, we incurred $580,000 in mineral property costs for Encino Gordo and Guazapares properties pertaining to a deferral agreement.  At February 29, 2008, we tested the carrying amounts of Encino Gordo and Guazapares properties for recoverability.  Based on our tests, we concluded that the sum of undiscounted cash flows expected to result from the use and eventual disposition of Encino Gordo and Guazapares properties was nil as the properties have no known reserves. Accordingly, a mineral property impairment loss of $580,000 has been recognized for the year ended February 29, 2008. Impairment of mineral property costs in 2008 increased to $580,000 compared to $259,000 for 2007. If we are able to raise additional funds to continue with our business plan, we anticipate that exploration expenditures will increase in fiscal 2008 as a result of exploration activities on our Mexican mineral properties.  Our interest expense decreased to $57,633 for 2008 compared to $2,293,904 for 2007. The higher interest expense in 2007 pertains to convertible debentures issued by the Company in March and April of 2006. The Company recorded a beneficial conversion feature of $1,359,300 as interest expense and $906,200 as relative fair value of the warrants in relation to the convertible debt. The Company did not incur interest expense related to convertible debt in 2008.  Loss  Our net loss increased to $8,096,604 for 2008 compared to $7,393,034 for 2007, representing an increase of $704,570. This change in our loss was primarily attributable to higher investor relations expenses, exploration expense and impairment of property costs in 2008. The non-cash components of stock-based compensation and impairment of mineral property costs were $2,454,000 and $580,000 respectively, for a total of $3,034,000 compared to the net loss for the year of $8,096,604. In 2007, the non-cash components of stock-based compensation and impairment of mineral property costs were $2,445,000 and $259,000 respectively, for a total of $2,704,000 compared to the net loss for the year of $7,393,034.  53    We anticipate that we will continue to incur a loss until such time as we can commence the development stage of our operations and achieve significant revenues from sales of gold recovered from our Mexican mineral properties, if ever. There is no assurance that we will commence the development stage of our operations at any our Mexican mineral properties or achieve revenues.  Liquidity and Capital Resources  Since inception, we have undergone two unsuccessful business combinations, which have caused us to incur significant liabilities and have resulted in the accumulation of a substantial deficit during the exploration stage. As of February 29, 2008, we had total assets of $858,000, total liabilities of $2,235,000, and a deficit of $33,828,000 accumulated during the exploration stage.  Cash and Working Capital  We had cash of $12,947 as of February 29, 2008, compared to cash of $13,148 as of February 28, 2007. We had working capital deficiency of $1,810,905 as of February 29, 2008, compared to a working capital deficiency of $44,980 as of February 28, 2007.  We will require additional financing during the current fiscal year according to our planned exploration activities. We plan to spend approximately $7,111,000 from March 2008 to December 2008 to carry out exploration and administration activities on our Mexican mineral properties, and in the event that our exploration is successful on our Cieneguita Property, we anticipate spending a further $2,200,000 on milling equipment and building a plant to put that property into production. We anticipate spending approximately $1,400,000 during the next 12 months on general and administrative costs. We presently do not have sufficient financing to enable us to complete these plans and will require additional financing to perform future exploration work on our Mexican mineral properties. Our actual expenditures on these activities will depend on the amount of funds we have available as a result of our financing efforts. There is no assurance that we will be able to raise the necessary financing.  The amount of working capital could be adversely affected further in the event claims are made against us alleging that certain shares we previously issued pursuant to Form S-8 registration statements constituted an illegal public offering because the company was a shell company at the time and, as a result, was not eligible to use Form S-8 for registration of shares under the Securities Act of 1933. In August and October of 2005, the Company issued shares of common stock to an officer of the Company, as compensation for consulting services. The two share issuances were for a combined total of 30,000 shares and each of the share issuances was made pursuant to a registration statement on Form S-8 under the Securities Act of 1933. Although the Company believes these shares were properly issued, a claim could be made that issuance of the shares constituted an illegal public offering because the Company was a shell company at the time. Shell companies  (i.e. companies which have no or nominal operations and either (i) no or nominal assets; (ii) assets consisting solely of cash and cash equivalents; or (iii) assets consisting of any amount of cash and cash equivalents and nominal other assets) are not eligible to use Form S-8 for registration under the Securities Act of 1933. If either of these transactions did violate federal securities laws, subsequent purchasers of the shares may have claims against us for damages or for rescission of their purchase transaction and recovery of the full subscription price paid, together with interest. As of the date of this annual report, no one has made or threatened any claim against us alleging violation of the federal securities laws. In the event such claims were successfully asserted there is no assurance that we would have sufficient funds available to pay and it is likely that we would be required to use funds currently designated as working capital for that purpose. That would substantially reduce the amount of working capital available for other purposes and, in that event, we could be forced to cease or discontinue certain operations and to liquidate certain assets to pay our liabilities, including, but not limited to, rescission claims.  Cash Used in Operating Activities  Cash used in operating activities increased to $3,837,069 for the fiscal year ended February 29, 2008 compared to $2,646,000 for the fiscal year ended February 28, 2007. The cash used in operating activities came primarily from exercise of warrants into shares of common stock. It was primarily used for general and administrative costs and for the exploration programs on the properties.  Cash Used in Investing Activities   54   Cash used in investing activities decreased to $172,036 for the fiscal year ended February 29, 2008 compared to $375,384 for the fiscal year ended February 28, 2007 for the purchase of equipment.  Financing Activities  Cash provided by financing activities increased to $4,027,811for the fiscal year ended February 29, 2008 compared to $2,557,736 for the fiscal year ended February 28, 2007. All cash provided by financing activities in 2007 was provided by convertible debt, exercise of warrants and share issuances. Cash provided by financing activities was used to fund our operating and investing activities.  We anticipate continuing to rely on equity sales of our common stock or issuance of debt in order to continue to fund our business operations. Issuances of additional shares will result in dilution to our existing shareholders.  In January 2006, the Company began issuing convertible debentures, with principal and accrued interest at 7% per year, convertible into units at the option of the holder. Each unit consists of a warrant to purchase 25,000 of the Companys shares of common stock at $1.00 per share and $25,000 of debt, which may be converted to shares of common stock at $0.50 per share and is exercisable until April 30, 2008. As of February 28, 2006, the Company had issued convertible debentures in the amount of $652,000. In addition, the warrants are redeemable by the Company, at $0.01 per share, in the event the Companys common stock closes with a bid price, on average, over $3.00 per share for a consecutive 20-day period and settled on a physical basis.  In order to get assistance with financing activities, on January 30, 2006, the Company entered into a Consulting Agreement with G.M. Capital Partners, Ltd., a British Virgin Islands company (GM Capital). Under the agreement, GM Capital will provide the Company with a variety of services including financial public relations, strategic planning, acquisition consulting and assistance in securing equity or debt financing. Specifically, GM Capital agreed to provide financial public relations counsel services including (i) being a liaison between the Company and its stockholders; (ii) advising the Company with respect to existing and potential market makers, broker-dealers, underwriters and investors as well as being the liaison for the Company with respect to communications and information (e.g., interviews, press releases, stockholder reports, etc.) as well as planning, designing, developing, organizing, writing and distribution such communications and information; (iii) assisting the Company in establishing an investor relations program and advising the Company with respect to stockholder meetings, interviews of Company officers by the financial media, and interviews of Company officers by analysts, market markers, broker-dealers and other members of the financial community; and (iv) assisting in making the Company, its management, products and services, and financial situation and prospects, known to the financial press and publications, broker-dealers, mutual funds, institutional investors, market makers, analysts, investment advisors and other members of the financial community. GM Capital also agreed to provide strategic planning services, which included (i) consulting with the Company as to, the management, marketing, consulting, strategic planning, corporate organization and structure, financial matters in connection with the operation of the business of the Company, expansion of projects; (ii) reviewing and advising the Company regarding its overall progress, needs and condition; (iii) assisting the Company in the monitoring of services provided by the Companys advertising firm, public relations firm and other non-legal professionals to be employed by the Company; and (iv) advising the Company on the continued development of an investor relations program and the stimulation of interest in the Company by institutional investors and other members of the financial community.  Under the terms of the agreement, the Company will pay GM Capital the following: (i) a monthly fee of $10,000, (ii) 10% success fee for any financing facilitated by GM Capital outside of the United States, and (iii) the issuance of a total of 5,000,000 warrants, each of which entitles the holder to purchase one share of the Companys common stock.. The warrants are exercisable at the right of the holder, have no redemption features, and are settled on a physical basis. The warrants include 1,000,000 Series A Warrants exercisable at $0.50 per share, 1,000,000 Series B Warrants exercisable at $0.75 per share, 1,000,000 Series C Warrants exercisable at $1.00 per share, 1,000,000 Series D Warrants exercisable at $1.25 per share, and 1,000,000 Series E Warrants exercisable at $1.50 per share. The Series A Warrants will be fully vested upon issuance. They will be exercisable at any time following their issuance but will expire on June 30, 2007 if not fully exercised on or before that date. The remaining series of Warrants will each vest and become exercisable only at the time that the immediately preceding series has been fully exercised. Therefore, the Series B Warrants will vest only upon the timely exercise of all Series A Warrants, and the same restriction will apply to each of the succeeding series of warrants (i.e. the Series C, D and E Warrants). Unless terminated earlier as a result of failure to vest, the Series B and Series C Warrants will each expire on December 31, 2007 and the Series D and Series E Warrants will each expire on December 31, 2008. However, the Agreement also stipulates that G.M. Capital cannot exercise any warrants if, after the exercise, G.M. Capital would own 4.99% or more of the issued and outstanding common stock of Mexoro. G.M. Capital is an accredited investor. These warrants were issued pursuant an exemption from registration under Regulation S of the Securities Act of 1933, as amended. The fair value of the 5,000,000 warrants was determined using the Black-Scholes option pricing model using a  55   ten-year expected life of the option, a volatility factor of 152%, a risk-free rate of 5% and no assumed dividend rate and totals $3,898,000 of stock-based compensation expense which is amortized over the twenty four month term of the GM Capital contract at $487,250 every quarter until November 30, 2007.  On August 31, 2006, the Company entered into an Amended Consulting Agreement with G.M. Capital. All of the terms remained the same except for the following:  (1)G.M. Capital represented that it does fall within United States jurisdiction in regard to this contract.(2)G.M. Capital is no longer required to provide services regarding the acquisition of a business because the Company does not plan to acquire a business in the near future.  (3)G.M. Capital clarified that the investors, market makers, and other financial industry contacts which it will speak to in regard to the Company are non-United States persons.(4)The Company acquired the sole discretion to determine how many Warrants G.M. Capital can exercise in order to restrict G.M. Capitals beneficial ownership at any one time to no more than 4.99% of the issued and outstanding shares of the Company.  (5)G.M. Capital will no longer be the liaison between the Company and its stockholders.(6)G.M. Capital will no longer advise the Company about potential market makers, broker-dealers, underwriters and investors.  (7)The Warrants were revised to remove the liquidated damages provision related to the registration rights of the holders of the Warrants.  Furthermore, we had amended our agreement with G.M. Capital to eliminate any reference whereby G.M. Capital would assist us in identifying, evaluating, structuring, negotiating and closing acquisitions. In the event we discovered no material ore reserves and have no more exploration plans to continue after June 2008 we would be without the services of G.M. Capital to assist us in reformulating the business plan of the Company. If we should abandon our exploration strategy, current management has sufficient expertise to reformulate the business plan and pursue other options without the help of G.M. Capital. G.M. Capitals main function was to identify and introduce potential investors to us in foreign jurisdictions for raising capital through the sale of equity or debt.  In May 2008, the Company verbally terminated the agreement with G.M. Capital for providing assistance in financing activities.  On March 4, 2006, the Company agreed to issue 1,651,200 shares of common stock at a price of $0.25 per share to settle $412,800 in promissory notes payable. As a condition, the promissory note holders waived all accrued interest payable on the notes. On April 6, 2006, these shares were issued and the Company recorded a $7,259 gain on settlement of debt.  On April 3, 2006 and May 31, 2006, the Company issued 550,000 shares of common stock and 200,000 shares of common stock respectively and closed a private placement for total proceeds of $375,000. As at February 28, 2006, the Company had received $170,000 of subscriptions for this unit offering. Units consisted of one share of common stock and one-half of one warrant. Each full warrant entitles the investor to purchase an additional share of the Companys common stock at a price of $1.00 per share and is exercisable until April 30, 2008. The units were priced at $0.50 each.  During the quarter ended May 31, 2006, the Company issued a total of $2,265,500 convertible debentures. The convertible debentures, with principal and accrued interest at 7% per year are convertible into $25,000 units at the option of the holder. Each unit consists of a warrant to purchase 25,000 of the Companys shares of common stock at $1.00 and $25,000 of debt, which may be converted to shares of common stock at $0.50 per share and is exercisable until April 30, 2008. In addition, the warrants are redeemable by the Company, at $0.01 per share, in the event the Companys common stock closes with a bid price, on average, over $3.00 per share for a consecutive 20-day period. Further, under the terms of the debenture, until May 2007, the Company is prohibited from effecting or entering into an agreement to affect any subsequent financing involving a Variable Rate Transaction. The term Variable Rate Transaction means a transaction in which the Company issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of common stock at a conversion, exercise or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of common stock at any time after the initial issuance of such debt or equity securities.  The holders of the debentures converted all of the debentures to shares of common stock at $0.50 per share in June 2006. The Company issued 5,835,000 shares and 2,917,500 warrants to debenture holders upon the conversion. We have paid to the convertible debenture holders a total of $58,308, which is their accumulated interest on the debentures. During August  56   2006, the Company cancelled 50,000 shares of common stock with respect to the conversion and 25,000 warrants with respect to this conversion due to non-payment of subscription funds.  Going Concern  Our financial statements have been prepared on a going concern basis, which assumes the realization of assets and settlement of liabilities in the normal course of business. Our ability to continue as a going concern is dependent upon our ability to generate profitable operations in the future and/ or to obtain the necessary financing to meet our obligations and repay our liabilities arising from normal business operations when they become due. The outcome of these matters cannot be predicted with any certainty at this time and raise substantial doubt that we will be able to continue as a going concern. Our financial statements do not include any adjustments to the amount and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern.  The Company has a history of operating losses and will need to raise additional capital to fund its planned operations. As at February 29, 2008, the Company had working capital deficiency of $1,810,011 (2007 - $44,980 working capital) and an accumulated deficit during the exploration stage of $33,828,000 (2007  $25,731,407). These conditions raise substantial doubt about the Companys ability to continue as a going concern.  Off-Balance Sheet Arrangements  We currently do not have any off-balance sheet arrangements which have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to our investors.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.  In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Mexoro Minerals Ltd. as of February 29, 2008, and the results of its operations and its cash flows for the year ended February 29, 2008 and the period from March 1, 2004 (Exploration Stage) to February 29, 2008, in conformity with accounting principles generally accepted in the United States of America.

These conditions raise substantial doubt about its ability to continue as a going concern. Managements plans regarding those matters also are described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

MEXORO MINERALS LTD. (An Exploration Stage Company) Notes to the Consolidated Financial Statements (Expressed in U.S. Dollars) Years Ended February 29, 2008 and February 28, 2007  1.BASIS OF PRESENTATION  Mexoro Minerals Ltd. (formerly Sunburst Acquisitions IV, Inc.) ("Mexoro" or the Company) was incorporated in the state of Colorado on August 27, 1997 and on February 15, 2006 its name was changed to Mexoro Minerals Ltd. The Company was formed to seek out and acquire business opportunities. Between 1997 and 2003, the Company was engaged in two business acquisitions and one business opportunity, none of which generated a significant profit or created sustainable business. All were sold or discontinued. Currently, the main focus of the Companys operations is in Mexico.  The Company had previously been pursuing various business opportunities and, effective March 1, 2004, the Company changed its operations to mineral exploration. Accordingly, as of March 1, 2004 the Company is considered to be an exploration stage company.  On May 25, 2004, the Company completed a Share Exchange Agreement with Sierra Minerals and Mining, Inc. (Sierra Minerals), a Nevada corporation, which caused Sierra Minerals to become a wholly-owned subsidiary. Sierra Minerals held certain rights to properties in Mexico that the Company now owns or has an option to acquire. Through Sierra Minerals, the Company entered into a joint venture agreement with Minera Rio Tinto, S.A. de C.V. (MRT), a company duly incorporated pursuant to the laws of Mexico, which is controlled by an officer of the Company. In August 2005, the Company cancelled the joint venture agreement in order to directly pursue the mineral exploration opportunities through a wholly-owned Mexican subsidiary, Sunburst Mining de Mexico S.A. de C.V. (Sunburst de Mexico). On August 25, 2005, Sunburst de Mexico, Mexoro and MRT entered into agreements providing Sunburst de Mexico the right to explore and exploit certain properties in Mexico. In December 2005, the Company and Sunburst de Mexico entered into a new agreement with MRT (the New Agreement) (note 5). On January 20, 2006, Sierra Minerals was dissolved.  2.SIGNIFICANT ACCOUNTING POLICIES  (a)Principles of consolidation  The accompanying financial statements include the accounts and activities of Mexoro and its wholly-owned subsidiary, Sunburst de Mexico. All intercompany balances and transactions have been eliminated in consolidation.  (b)Financial instruments  (i)Fair value  The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities and promissory notes approximate their fair values because of the short-term maturity of these financial instruments. The carrying value of convertible debentures approximates their fair value because these instruments earn interest at the market rate.  (ii)Interest rate risk  The Company is not exposed to significant interest rate risk due to the short-term maturity of its monetary current assets and current liabilities. The convertible debentures are not exposed to interest rate risk because the interest rate is fixed to maturity.  (iii)Credit risk  The Company's financial assets that are exposed to credit risk consist primarily of cash that is placed with major financial institutions.    (iv)Translation risk


67


The Company translates the results of non-U.S. operations into U.S. currency using rates approximating the average exchange rate for the year. The exchange rate may vary from time to time. This risk is considered moderate, as the Companys mining project expenses are recorded in Mexican pesos and converted to U.S. currency.  (c)Equipment  Equipment is recorded at cost less accumulated amortization. Amortization is provided on the following basis:  Software2 years straight-lineMachinery10% declining-balanceVehicles25% declining-balanceComputer equipment30% declining-balanceOffice equipment30% declining-balance  (d)Cash and cash equivalents  The Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents.  (e)Mineral property costs  The Company has been in the exploration stage since March 1, 2004, and has not yet realized any revenues from its planned operations. It is primarily engaged in the acquisition and exploration of mining properties. Mineral property exploration costs are expensed as incurred. Mineral property acquisition costs are initially capitalized when incurred using the guidance in EITF 04-02, Whether Mineral Rights Are Tangible or Intangible Assets. The Company assesses the carrying costs for impairment under SFAS No. 144, Accounting for Impairment or Disposal of Long Lived Assets at each fiscal quarter end. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs then incurred to develop such property, are capitalized. Such costs will be amortized using the units-of-production method over the estimated life of the probable reserve. If mineral properties are subsequently abandoned or impaired, any capitalized costs will be charged to operations.  (f)Basic and diluted income (loss) per share  The Company computes income (loss) per share in accordance with SFAS No. 128, "Earnings per Share", which requires presentation of both basic and diluted earnings per share (EPS) on the face of the statement of operations. Basic EPS is computed by dividing income (loss) available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential shares of common stock outstanding during the period using the treasury stock method and convertible preferred stock using the if-converted method. In computing diluted EPS, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Diluted EPS excludes all dilutive potential shares if their effect is anti-dilutive. All previously stated share and per share balances have been restated to give retroactive effect to the 1:50 reverse stock split that occurred on February 15, 2006. Dilutive loss per share has not been presented because the effects of all common share equivalents were anti-dilutive.  (g)Impairment or disposal of long-lived assets  In August 2001, the FASB issued Statement No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (FAS 144). FAS 144 clarifies the accounting for the impairment of long-lived assets and for long-lived assets to be disposed of, including the disposal of business segments and major lines of business. The Company has implemented FAS 144. Long-lived assets are reviewed when facts and circumstances indicate that the carrying value of the asset may not be recoverable. When necessary, impaired assets are written down to estimate fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates.


68


(h)Use of estimates  The preparation of financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 of estimate include the impairment of assets and rates for amortization, accrued liabilities, future income tax balances and the inputs used in calculating stock-based compensation. Actual results could differ from those estimates and would impact future results of operations and cash flows.  (i)Consideration of other comprehensive income items  SFAS No. 130  Reporting Comprehensive Income requires companies to present comprehensive income (consisting primarily of net loss plus other direct equity changes and credits) and its components as part of the basic financial statements.  (j)Stock-based compensation  Effective March 1, 2004, the Company adopted the fair value based method of accounting for stock-based employee compensation in accordance with the provisions of SFAS No. 123 Accounting for Stock-Based Compensation, using the prospective transition method. Accordingly the Company recognized the fair value of stock-based employee compensation for all awards made after March 1, 2004. The Company is in accordance with Emerging Issues Task Force No. 96-18 "Accounting for Equity Instruments That are Issued to Other than Employees for Acquiring, or in Conjunction with Selling, Goods or Services" ("EITF 96-18"), with respect to options and warrants issued to non-employees.  Effective March 1, 2005, the Company adopted the fair value recognition provisions of SFAS No. 123R Share Based Payments (SFAS No. 123R), using the modified prospective transition method. Under that transition method, compensation cost is recognized for all share-based payments granted prior to, but not yet vested as of March 1, 2005, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and compensation cost for all share-based payments granted subsequent to March 1, 2004, based on the grant-date fair value estimated in accordance with the provisions of SFAS 123R. Results for prior periods have not been restated. As of March 1, 2004, there were no unvested options; and therefore, there was no effect on the Companys reported loss from operations, cash flows or loss per share as a result of adopting SFAS No. 123R.  All transactions in which goods or services are the consideration received for the issuance of equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable. Equity instruments issued to employees and the cost of the services received as consideration are measured and recognized based on the fair value of the equity instruments issued (see note 11).  (k)Income taxes  The Company accounts for income taxes in accordance with SFAS No. 109  Accounting for Income Taxes. Deferred tax assets and liabilities are recognized with respect to the tax consequences attributable to differences between the financial statement carrying values and tax basis of existing assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. Further, the effect on deferred tax assets and liabilities of changes in tax rates is recognized in income in the period that includes the enactment. A valuation allowance against deferred tax assets is recorded. If based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.  (l)Foreign currency translation  Mexoro and its subsidiary Sunburst de Mexico maintain accounting records in their functional currencies, U.S. dollars and Mexican pesos, respectively. Mexoro and Sunburst de Mexico translate foreign currency transactions into the respective functional currencies in the following manners: at the transaction date, each asset, liability, revenue and expense is translated into the functional currency by the use of the exchange rate in effect at that date; at the period end, foreign currency monetary assets and liabilities are re-evaluated into the functional currency by using the exchange rate in effect at the balance sheet date. The resulting foreign exchange gains and losses are included in operations.


69


In preparing consolidated financial statements, the Company translates the assets and liabilities of its subsidiary into U.S. dollars at the exchange rate in effect at the balance sheet date. Revenue and expenses are translated into U.S. dollars at the average exchange rate for the applicable period. Any gain or loss from such translations is included in stockholders equity as a component of other comprehensive income.  (m)Asset retirement obligations  The company accounts for asset retirement obligations (ARO) in accordance with Financial Accounting Standards Board (FASB) Statement No. 143, Accounting for Asset Retirement Obligations (FAS 143). This accounting standard applies to the fair value of a liability for an ARO that is recorded when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. Obligations associated with the retirement of these assets require recognition in certain circumstances: (1) the present value of a liability and offsetting asset for an ARO, (2) the subsequent accretion of that liability and depreciation of the asset, and (3) the periodic review of the ARO liability estimates and discount rates. In 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations  An Interpretation of FASB Statement No. 143 (FIN 47), which was effective for the company on December 31, 2005. FIN 47 clarifies that the phrase "conditional asset retirement obligation," as used in FAS 143, refers to a legal obligation to perform asset retirement activity for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the company. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. Uncertainty about the timing and/or method of settlement of a conditional ARO should be factored into the measurement of the liability when sufficient information exists. FAS 143 acknowledges that in some cases, sufficient information may not be available to reasonably estimate the fair value of an ARO. FIN 47 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an ARO.  The Company is in an early stage of mineral exploration and has no known reserves as of February 29, 2008. Accordingly, the Company cannot reasonably estimate the fair value of those obligations because of their indeterminate settlement dates.  (n)Recent accounting pronouncements  (i)In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments, an amendment of FASB Statements No. 133 and 140. This statement permits fair value re-measurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. It establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation. In addition, SFAS 155 clarifies which interest-only strips and principal-only strips are not subject to the requirements of Statement 133. It also clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives. SFAS 155 amends Statement 140 to eliminate the prohibition on a qualifying special purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. This statement is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006. The adoption of this standard did not have a material effect on the Companys results of operations or financial position.   (ii)In September 2006, the Securities and Exchange Commission (SEC) released SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (SAB 108). SAB 108 provides interpretive guidance on the SECs views on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The Company adopted SAB 108 during the fourth quarter of 2006. The adoption did not have a material impact on the Companys financial position, cash flows, or results of operations.


70


(iii)In September 2006, FASB issued SFAS No. 157, Fair Value Measurements. SFAS No. 157 provides guidance for using fair value to measure assets and liabilities. It clarifies that for items that are not actively traded, such as certain kinds of derivatives, fair value should reflect the price in a transaction with a market participant, including adjustment for risk, not just the companys mark-to-model value. SFAS No. 157 also requires expanded disclosure of the effect on earnings for items measured using unobservable data. Fair value refers to the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007.   (iv)In July 2006, FASB issued Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes  An Interpretation of FASB Statement No. 109. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprises financial statements in accordance with FASB Statement No. 109, and also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 is effective for financial statements issued for fiscal years beginning after December 15, 2006. The adoption of this standard is not expected to have a significant impact on the Companys consolidated financial statements.  (v)On February 15, 2007, the FASB issued SFAS Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. This Statement permits companies and not-for-profit organizations to make a one-time election to carry eligible types of financial assets and liabilities at fair value, even if fair value measurement is not required under U.S.GAAP. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the effect of the adoption of SFAS No. 159.  (vi)In December 2007, the FASB issued SFAS No. 141 (R), Business Combinations, and SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements. SFAS No. 141 (R) requires an acquirer to measure the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquiree at their fair values on the acquisition date, with goodwill being the excess value over the net identifiable assets acquired. SFAS No. 160 clarifies that a noncontrolling interest in a subsidiary should be reported as equity in the consolidated financial statements. The calculation of earnings per share will continue to be based on income amounts attributable to the parent. SFAS No. 141 (R) and SFAS No. 160 are effective for financial statements issued for fiscal years beginning after December 15, 2008. Early adoption is prohibited. We have not yet determined the effect on our consolidated financial statements, if any, upon adoption of SFAS No. 141 (R) or SFAS No. 160.   3.GOING CONCERN  The accompanying financial statements have been prepared on a going-concern basis. The Company has a history of operating losses and will need to raise additional capital to fund its planned operations. As at February 29, 2008, the Company had a working capital deficiency of $1,810,905 (2007 - $44,980 working capital) and a cumulative loss during the exploration period of $33,828,011 (2007 - $25,731,407). These conditions raise substantial doubt about the Companys ability to continue as a going concern.  The Company intends to reduce its cumulative loss through the attainment of profitable operations, from its investment in a Mexican mining venture (note 5). In addition, the Company has conducted private placements of convertible debt and common stock (note 9), which have generated a portion of the initial cash requirements of its planned Mexican mining ventures (note 5).  4.EQUIPMENT  February 29, 2008February 28,2007CostAccumulated DepreciationNet BookNet BookValueValue

In August 2005, the Company formed its wholly owned subsidiary, Sunburst de Mexico, which allowed the Company to take title to the properties into the name of Sunburst de Mexico. On August 25, 2005 the Company entered into property agreements with MRT, which provided Sunburst de Mexico options to purchase the mineral concessions of the Cieneguita and Guazapares properties and the right of refusal on three Encino Gordo properties. The Company also entered into an exploration and sale agreement, in October 2006, with Minera Emilio for mineral concessions of the Sahauyacan Property.  In August 2005 the parties also entered into an operators agreement, that gave MRT the sole and exclusive right and authority to manage the Cieneguita Property, and a share option agreement which granted MRT the exclusive option to acquire up to 100% of all outstanding shares of Sunburst de Mexico if the Company did not comply with the terms of the property agreements. The operating agreement and share option agreement have subsequently been cancelled.


72


The material provisions of the Companys property agreements are as follows:     Cieneguita  MRT assigned to Sunburst de Mexico, with the permission of the Cieneguita owner, Corporativo Minero, S.A. de C.V. (Corporativo Minero), all of MRTs rights and obligations acquired under a previous agreement, the Cieneguita option agreement, including the exclusive option to acquire the Cieneguita Property for a price of $2,000,000. As the Cieneguita Property was not in production by May 6, 2006, Sunburst de Mexico was required to pay $120,000 to Corporativo Minero to extend the contract. Corporativo Minero agreed to reduce the obligation to $60,000, of which $10,000 was paid in April 2006 and the balance paid on May 6, 2006. The Company made this payment to Corporativo Minero and the contract was extended.  The Company has the obligation to pay a further $120,000 per year for the next 13 years and the balance of the payments in the 14th year, until the total amount of $2,000,000 is paid. The Company renegotiated the payment due May 6, 2007, to $60,000 payable on November 6, 2007, which was paid, and the balance of $60,000 was paid on December 20, 2007.  In the alternative, if the Cieneguita Property is put into production, of which there is no guarantee, the Company must pay the Cieneguita owners $20 per ounce of gold produced, if any, from the Cieneguita Property to the total $2,000,000 due. In the event that the price of gold is above $400 per ounce, the property payments payable to the Cieneguita owners from production will be increased by $0.10 for each dollar increment over $400 per ounce. The total payment of $2,000,000 does not change with fluctuations in the price of gold. Non-payment of any portion of the $2,000,000 total payment will constitute a default. In such case, the Cieneguita owners will retain ownership of the concessions, but the Company will not incur any additional default penalty. MRT retained no interest in the Cieneguita Property.  Guazapares  MRT assigned to Sunburst de Mexico, with the consent of the Guazapares Property owner Compañía Minera, S.A. de C.V. (Compañía Minera), MRTs rights and obligations concerning the Guazapares Property, including the exclusive option, for a term of four years, to purchase seven of the Guazapares Property concessions upon payment of $910,000. The total payments for the Company to acquire and retain 100% ownership of all eight concessions are as follows: November 30, 2005 - $100,000 (this payment date was extended  see below), October 31, 2006 - $60,000 (this payment date was extended to February 28, 2007, then to May 31, 2007 and then to August 31, 2007- see below), August 2, 2007 - $140,000 (see below), August 2, 2008 - $110,000 and August 2, 2009 - $500,000.  On September 19, 2007, Sunburst de Mexico, Mexoro and MRT entered into an agreement to defer any and all property payments regarding Guazapares, currently owing to MRT and which would otherwise become due by December 31, 2007, until such time as Sunburst de Mexico and Mexoro have sufficient funds to make the payments, in the opinion of the disinterested directors of Mexoro.  Mexoro agreed to issue 250,000 shares to MRT and/or assignees, in consideration for the deferral of any and all Guazapares property payments currently outstanding and those arising on or before December 31, 2007  In return, Sunburst de Mexico granted MRT a 2.5% NSR and the right to extract from the Guazapares concessions up to 5,000 tons per month of rock material; this right will terminate on exercise of the option to purchase the concessions. Otherwise, MRT retained no interest in the Guazapares Property.   San Francisco (Guazapares)  MRT assigned to Sunburst de Mexico, for a term of 60 months, commencing from June 25, 2004 (the Option Period), with the consent of the San Francisco concessions owner Minera Rachasa, S.A. de C.V. (Minera Rachasa), MRTs rights and obligations acquired under the San Francisco option agreement, including the option to purchase the San Francisco concessions for a price of $250,000 on June 25, 2009.


73

The 2007 Option Plan has the purpose (a) to ensure the retention of the services of existing executive personnel, key employees, and directors of the Company or its affiliates; (b) to attract and retain competent new executive personnel, key employees, consultants and directors; (c) to provide incentive to all such personnel, employees,


76


consultants and directors to devote their utmost effort and skill to the advancement and betterment of the Company, by permitting them to participate in the ownership of the Company and thereby in the success and increased value of the Company; and (d) allowing vendors, service providers, consultants, business associates, strategic partners, and others, with or that the board of directors anticipates will have an important business relationship with the Company or its affiliates, the opportunity to participate in the ownership of the Company and thereby to have an interest in the success and increased value of the Company.  The 2007 Option Plan constitutes a single omnibus plan, but is composed of two parts. The first part is the nonqualified stock option plan (NQSO Plan) which provides grants of nonqualified stock options (NQSOs). The second part is the restricted shares plan (Restricted Shares Plan) which provides grants of restricted shares of Company common stock (Restricted Shares). The maximum number of shares of common stock that may be purchased under the plan is 6,000,000.  Pursuant to a consulting agreement between the Company and GM Capital Partners Inc. (GM Capital), signed January 31, 2006, the Company granted 5,000,000 warrants (see note 11). The agreement provided for the provisions of financial public relations services from December 1, 2005 to November 30, 2007. The fair value of the 5,000,000 warrants totaled $3,898,000 and was determined using the Black-Scholes option pricing model using weighted averages: 2.38 year expected life of the warrants, a volatility factor of 152%, a risk-free rate of 5% and an assumed dividend rate of 0% The weighted average fair value of the warrant was $0.78 per warrant, while the weighted average stock price on the dates granted was $1.00. The fair value was amortized over the 24-month term of the contract and the Company recorded $487,250 as stock-based compensation expense and an offsetting credit to additional paid-in capital every quarter until November 30, 2007.  In the year ended February 29, 2008, the Company awarded 1,915,000 options to purchase common shares (2007  800,000) and recorded stock-based compensation expense of $939,741 (2007 - $496,000). The weighted average fair value of each option granted for the year ended February 29, 2008 was $0.71. The following weighted average assumptions were used for the Black-Scholes option-pricing model used to value stock options granted in 2008 and 2007:  20082007Expected volatility66.82% - 73.37%152%Weighted-average volatility71.32%152%Expected dividend rate--Expected life of options in years3 - 1010Risk-free rate4.04% - 4.91%5.00%  There were no capitalized stock-based compensation costs at February 29, 2008 or February 28, 2007.

The weighted average fair value of the warrant was $0.57 per warrant, while the weighted average stock price on the date granted was $1.26. Stock-based compensation for these warrants of $64,000 is being amortized over the six month term of the promissory notes starting on October 17, 2007.

The fair value of the 5,000,000 warrants totaled $3,898,000 and was determined using the Black-Scholes option pricing model using weighted averages: 2.38 year expected life of the warrants, a volatility factor of 152%, a risk-free rate of 5% and an assumed dividend rate of 0% The weighted average fair value of the warrant was $0.78 per warrant, while the weighted average stock price on the dates granted was $1.00.

During the Companys two most recent fiscal years and any subsequent interim period up to and including the date of Smythe Ratcliffes resignation, there have been no disagreements with Smythe Ratcliffe on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Smythe Ratcliffe, would have caused them to make reference thereto in their report on the financial statements for such periods.  On December 7, 2007, the board of directors of the Company appointed the firm of Meyler & Company, LLC (Meyler & Company), One Arin Park, 1715 Highway 35, Middletown, NJ 07748, as the independent auditor of the Company for the fiscal year ending February 29, 2008.  During the two most recent fiscal years or subsequent interim period, neither the Company, nor anyone on its behalf, consulted with Meyler & Company regarding the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, nor did the entity of Meyler & Company, provide advice to the Company, either written or oral, that was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue. Further, during the Company's two most recent fiscal years or subsequent interim period, the Company has not consulted the entity of Meyler & Company, on any matter that was the subject of a disagreement or a reportable event.  ITEM 9A(T).   CONTROLS AND PROCEDURES.  Disclosure Controls and Procedures  The Securities and Exchange Commission defines the term disclosure controls and procedures to mean a company's controls and other procedures of an issuer that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commissions rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuers management, including its chief executive and chief financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.  The Company maintains such a system of controls and procedures in an effort to ensure that all information which it is required to disclose in the reports it files under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified under the SEC's rules and forms and that information required to be disclosed is accumulated and communicated to chief executive and chief financial officers to allow timely decisions regarding disclosure.  As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on this evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were not designed and were not effective in providing reasonable assurance of achieving the objectives of timely alerting them to material information required to be included in our periodic SEC reports and of ensuring that such information is recorded, processed, summarized and reported with the time periods specified because the Company did not have sufficient personnel resources with the accounting function to affect timely financial close.  Internal Control Over Financial Reporting  The management of the Company is responsible for the preparation of the financial statements and related financial information appearing in this Annual Report on Form 10-K/A. The financial statements and notes have been prepared in conformity with accounting principles generally accepted in the United States of America. The management of the Company also is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. A company's internal control over financial reporting is defined as a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over


82


financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.  Management, including the chief executive officer and chief financial officer, does not expect that the Company's disclosure controls and internal controls will prevent all error and all fraud. Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable, not absolute, assurance that the objectives of the control system are met and may not prevent or detect misstatements. Further, over time control may become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate.  With the participation of the chief executive officer and chief financial officer, our management evaluated the effectiveness of the Company's internal control over financial reporting as of February 29, 2008 based upon the framework in Internal Control Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation along with the report from the Companys independent registered public accounting firm, our management has concluded that, as of February 29, 2008, the Company had a material weakness in its internal control over financial reporting.  Specifically, the management determined that the Company did not have sufficient personnel resources with the accounting function to affect timely financial close process and to effectively evaluate and resolve certain routine and non-routine and/or complex accounting transactions.  To remediate our internal control weaknesses, management intends to implement the following measures:  1. The Company will add sufficient accounting personnel to properly segregate duties and to effect a timely, accurate preparation of the financial statements.  2. The Company will hire a qualified professional for the role of chief financial officer to oversee the accounting and finance function of Mexoro.  The additional hiring is contingent upon Mexoro getting funded through equity or debt for its continued exploration activities and corporate expenses. Mexoros management expects to secure funds in the coming fiscal year but provides no assurances that it will be able to do so.  This annual report 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 Securities and Exchange Commission that permit us to provide only management's report in this Annual Report on Form 10-K/A.  Changes in Internal Control over Financial Reporting  There were no changes in the Company's internal control over financial reporting that occurred during the last fiscal quarter, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

Mr. Sanders will contribute approximately 20 hours per week (approximately 30% of his time) to the business and operations of the Company.  Audit Committee  As our company is relatively small and a developmental company, we have neither an audit committee of the Board of Directors nor an audit committee financial expert, as such term is defined under the Securities Exchange Act. We believe that the members of our Board of Directors are collectively capable of analyzing and evaluating our financial statements and understanding our internal controls and procedures, including those pertaining to financial reporting.  In addition, we believe


84


that retaining an independent Director who would qualify as an audit committee financial expert would be overly costly and burdensome and is not warranted in light of our current size.  Code of Ethics  Our Board of Directors adopted a code of business conduct and ethics policy, the Code of Ethics. The Code of Ethics allows us to focus our Board of Directors and each Director and officer on areas of ethical risk, provide guidance to Directors to help them recognize and deal with ethical issues, provide mechanisms to report unethical conduct and help foster a culture of honesty and accountability.  Section 16(a) Beneficial Ownership Reporting Compliance  Section 16(a) of the Exchange Act requires our directors, officers (including a person performing a principal policy-making function) and persons who own more than 10% of a registered class of our equity securities to file with the Commission initial reports of ownership and reports of changes in ownership of our common stock and other equity securities of ours. Directors, officers and 10% holders are required by Commission regulations to send us copies of all of the Section 16(a) reports they file. Based solely upon a review of the copies of the forms sent to us and the representations made by the reporting persons to us, we believe that during the fiscal year ended December 31, 2007, our directors, officers and 10% holders complied with the filing requirements under Section 16(a) of the Exchange Act.  ITEM 11.  EXECUTIVE COMPENSATION.  The following table sets forth executive compensation for fiscal years ended February 29 and 28, 2008, 2007 and 2006. We have not paid any salaries or bonuses to any of our officers from our inception through the date hereof. We refer to all of these officers collectively as our "named executive officers".

Options Granted During the Last Fiscal Year  On April 7, 2008, the board of directors approved the granted of stock option according to the 2008 Nonqualified Stock Option Plan (2008 Option Plan) whereby the board is authorized to grant to employees and other related persons stock options to purchase an aggregate of up to 6,000,000 shares of the Company's common stock. Subject to the adoption of the 2008 Option Plan, all of the options were granted and vest, pursuant to the terms of the 2008 Option Plan in six equal installments, with the first installment vesting at the date of grant, the second installment vesting October 7, 2008, the third installment vesting April 7, 2009, the fourth installment vesting October 7, 2009, the fifth installment vesting April 7, 2010 and the last installment vesting October 7, 2010. As of February 29, 2008, the Company had not granted any options under the 2008 Option Plan.  Fiscal 2007  On February 26, 2007, the board of directors approved the granting of stock options according to the 2007 Nonqualified Stock Option Plan (the 2007 Option Plan). The 2007 Option Plan has the purpose (a) to ensure the retention of the services of existing executive personnel, key employees, and directors of the Company or its affiliates; (b) to attract and retain competent new executive personnel, key employees, consultants and directors; (c) to provide incentive to all such personnel, employees, consultants and directors to devote their utmost effort and skill to the advancement and betterment of the Company, by permitting them to participate in the ownership of the Company and thereby in the success and increased value of the Company; and (d) allowing vendors, service providers, consultants, business associates, strategic partners, and others, with or that the board of directors anticipates will have an important business relationship with the Company or its affiliates, the opportunity to participate in the ownership of the Company and thereby to have an interest in the success and increased value of the Company.  The 2007 Option Plan constitutes a single omnibus plan, but is composed of two parts. The first part is the nonqualified stock option plan (NQSO Plan) which provides grants of nonqualified stock options (NQSOs). The second part is the restricted shares plan (Restricted Shares Plan) which provides grants of restricted shares of Company common stock (Restricted Shares). The maximum number of shares of common stock that may be purchased under the plan is 6,000,000.  In fiscal 2007, options were granted as follows:  · On March 1, 2007, the Company granted 660,000 NQSOs to employees and consultants under the 2007 Option Plan at a price of $1.04 per common stock for a period of three years.  · On April 16, 2007, the Company granted 900,000 NQSOs to officers and directors under the 2007 Option Plan at a price of $1.15 per common stock for a period of three years.  · On August 15, 2007, the Company granted 75,000 NQSOs to an employee under the 2007 Option Plan at a price of $0.75 per common stock for a period of three years.  · On September 1, 2007, the Company granted 105,000 NQSOs to employees under the 2007 Option Plan at a price of $1.05 per common stock for a period of three years.  · On October 15, 2007 the Company granted 150,000 NQSOs to a former officer under the 2007 Option Plan at a price of $1.33 per common stock for a period of three years. These shares were subsequently cancelled when the officer resigned in November 2007.  · On December 21, 2007, the Company granted 25,000 NQSOs to a consultant under the 2007 Option Plan at a price of $0.90 per common stock for a period of three years.  The fair value of the 900,000 options granted to directors and officers was determined using the Black-Scholes option pricing model using a ten-year expected life of the option, a volatility factor of 152%, a risk-free rate of 5% and no assumed dividend rate.

Fiscal 2006  On February 27, 2006, the Company granted 800,000 ISOs under the ISO Plan to directors, officers and consultants at a price of $0.50 per common stock for a period of ten years. The ISOs vest in four equal installments, at the time of the grant and then every six months thereafter. Compensation cost, being the fair value of the options, is calculated to be $982,000 of which $248,000 is expensed on the date of issue and as the remainder vests.  The fair value of the 800,000 options was determined using the Black-Scholes option pricing model using a ten-year expected life of the option, a volatility factor of 152%, a risk-free rate of 5% and no assumed dividend rate.

Aggregate Option Exercises in Last Fiscal Year  None of the named executive officers exercised options during the year ended February 29, 2008.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE.  On September 18, 2007, the Company issued 500,000 common shares to MRT, a company controlled by our President and Director Mario Ayub>  The Company also issued MRT 250,000 shares of common stock were issued pursuant to the Encino Gordo contract. The Company issued 250,000 shares of common stock pursuant to an agreement in consideration of deferral of any and all Guazapares property payments currently outstanding and those arising on or before December 31, 2007. The shares were valued at $1.16 per share, based on the closing quoted market price on September 18, 2007.  We currently rent an office in Mexico for our wholly owned subsidiary Sunburst de Mexico. The office is located at C. General Retana, 706 Col. San Felipe, Chihuahua, Chih., Mexico, C.P. 31203. The lease is for two years that commenced on September 15, 2006, and we pay $900 per month for it. Previously, we leased an office and office services from MRT, a company controlled by Mario Ayub, an officer and director of the Company. We paid $950 per month for office rent and $5,000 per month for office services on a month to month basis.  Previous to February 29, 2008, we had been paying monthly management fees of $5,000 to Robert Knight (Knight Financial Ltd.), our former CEO, $3,710 from February 2007 to November 2007 to Tracy A. Moore, our former CFO, for corporate financial advisory services and $6,000 to Mario Ayub, our President and COO. We also paid $7,950 to Salil Dhaumya for CFO services from October 16 to November 30, 2007.  Indemnification of Officers and Directors  Our articles of incorporation, as amended, provide that, to the fullest extent permitted by Colorado law, our directors or officers shall not be personally liable to us or our shareholders for damages for breach of such director's or officer's fiduciary duty. The effect of this provision of our articles of incorporation, as amended, is to eliminate our rights and our shareholders rights (through shareholders' derivative suits on behalf of our company) to recover damages against a director or officer for breach of


90


the fiduciary duty of care as a director or officer (including breaches resulting from negligent or grossly negligent behavior), except under certain situations defined by statute. We believe that the indemnification provisions in our Articles of Incorporation, as amended, are necessary to attract and retain qualified persons as directors and officers.  Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Act" or "Securities Act") may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  Exclusion of Liability  Pursuant to the Colorado Corporation Code, the Companys articles of incorporation exclude personal liability for its directors for monetary damages based upon any violation of their fiduciary duties as directors, except as to liability for any breach of the duty of loyalty, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, acts in violation of Section 7-5-114 of the Colorado Corporation Code, or any transaction from which a director receives an improper personal benefit. This exclusion of liability does not limit any right which a director may have to be indemnified and does not affect any director's liability under federal or applicable state securities laws.  Conflicts of Interest  None of the officers of the Company will devote more than a portion of their time to the affairs of the Company. There will be occasions when the time requirements of the Companys business conflict with the demands of the officers other business and investment activities. Such conflicts may require that the Company attempt to employ additional personnel. There is no assurance that the services of such persons will be available or that they can be obtained upon terms favorable to the Company.  ITEM 14.
