In this Form 20-F, the Company may provide cross-references relevant to the information being provided.  These cross-references are provided for ease of reference only and are not meant to be exclusionary to other relevant information in this Form 20-F, which may relate to the disclosure in question.

SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

The information presented in or incorporated by reference in this Form 20-F includes both historical information and forward-looking statements (within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended) relating to the future results of Birch (including projections and business trends), which involve risks and uncertainties.

Numerous factors could cause actual results to differ materially from those in the forward-looking statements, including without limitation, continuing production by oil sands companies in the Company's market area, development of new competing or replacement technology, lack of market acceptance or insufficient demand, declining commodity prices, specifically the price of oil, inability of the Company to execute the business plan, failure to protect intellectual property, unsuccessful exploration of mineral properties and related activities, unfavourable changes in the regulatory environment including environmental, tax, land tenure or other regulatory regimes, the inability to finance future development and the dependence upon the abilities and continued participation of certain key employees or consultants of Birch.  As a result of the foregoing and other factors, no assurance can be given as to future results, levels of activity and achievements.

Investors are cautioned not to put undue reliance on forward-looking statements, and should not infer that there has been no change in the affairs of Birch since the date of this report that would warrant any modification of any forward-looking statement made in this document or other documents filed periodically with securities regulators.  All subsequent written and oral forward-looking statements attributable to Birch or persons acting on its behalf are expressly qualified in their entirety by this notice.  Except as required by law, Birch disclaims any intent or obligation to update publicly these forward-looking statements, whether as a result of new information, future events or otherwise.

Risk Factors

Birch is an Early Production Stage Company

Birch opened the Muskeg Valley Quarry, the initial starter quarry situated within the Hammerstone Project, in December 2005, under the regulatory approvals and operating permits received in August 2005.  The MVQ is fully operational, providing and selling a range of limestone aggregate products.  First commercial sales occurred in the second quarter of 2006.

In May 2006, Birch filed an application with the provincial regulatory authorities for the remainder of the Hammerstone Project, to integrate the existing MVQ with an expanded quarry and aggregate plant, as well as a limestone processing complex to produce limestone-based reagent products.

There are risks that the MVQ's ongoing operations may experience slowdowns and production interruptions and that operating costs may be higher than estimated.

Similarly, there are risks that the Hammerstone Project may be delayed or that the limestone processing complex may not commence operations.

These risks are due to many factors, including, without limitation:

•

breakdown or failure of equipment or processes;

•

production performance falling below expected levels of output or efficiency;

•

design errors;

•

contractor or operator errors;

•

non-performance by third-party contractors;

•

labour disputes, disruptions or declines in productivity;

•

increases in materials, equipment or labour costs;

•

inability to attract sufficient numbers of qualified workers;

•

delays in obtaining, or conditions imposed by, regulatory approvals;

•

changes in the scope of the development or operations;

•

violation of permit requirements;

•

disruption of energy supply; and

•

catastrophic events such as fires, earthquakes, storms or explosions.



The current operation and construction schedules may not proceed as planned, there may be delays and the development of the Hammerstone Project may not be completed on budget.  Any such delays will likely increase the costs and may require additional financing, which financing may not be available.  Actual costs to construct and develop the Hammerstone Project will vary from estimates and such variances may be significant.



Given the stage of development of the Hammerstone Project, various changes may be made prior to completing construction.  Based upon current scheduling, the Hammerstone Project is not expected to start commercial quicklime operations until 2009.  The information contained herein, including, without limitation, reserve and economic evaluations, is conditional upon receipt of all regulatory approvals and no material changes being made to the planned MVQ operations and the Hammerstone Project.

Mineral Reserve Quantities and Quality are Based on Estimates

There are numerous uncertainties inherent in estimating quantities of mineral reserves, including many factors beyond Birch's control, and no assurance can be given that the indicated level of reserves or recovery thereof will be realized.  In general, estimates of economically recoverable limestone reserves and the future net cash flow there from are based upon a number of factors and assumptions made as of the date on which the reserve estimates were determined, such as estimates of future demand for limestone products, geological and engineering estimates which have inherent uncertainties, the assumed effects of regulation by governmental agencies and estimates of future commodity prices and operating costs, all of which may vary considerably from actual results.  All such estimates are, to some degree, uncertain and classifications of reserves are only attempts to define the degree of uncertainty involved.  For these reasons, estimates of the economically recoverable limestone, the classification of such reserves based on risk of recovery and estimates of future net revenue expected there from, prepared by different engineers or by the same engineers at different times, may vary substantially.

Estimates with respect to mineral reserves that may be developed and produced in the future are often based upon volumetric calculations and upon analogy to similar types of reserves and/or estimates of future sales, rather than upon actual production history.  Estimates based on these methods generally are less reliable than those based on actual production history.  Subsequent evaluation of the same reserves based upon production history will result in variations, which may be material, in the estimated reserves.

Mineral reserve estimates may require revision based on actual production experience.  Mineral reserves have been determined based upon projected demand and estimated aggregate and quicklime prices and operating costs.  Market price fluctuations of aggregate, quicklime, cement and other product prices may render uneconomic the recovery of certain grades of limestone.  Moreover, short-term factors relating to oil sands development and world oil prices may impair profitability in any particular period.

No assurance can be provided as to the quantity or quality of the limestone to be produced from the quarry.

Birch Has a Lack of Cash Flows and Financing May Not be Available to the Company

Birch is a developing company and does not yet have sufficient revenues to meet its yearly operating and capital requirements. The Company has historically raised funds necessary to conduct its business primarily through issuance of equity or debt.  There is no guarantee the Company will be able to continue to raise funds through additional equity issuances, project debt financing, joint ventures and/or partnering arrangements.

The Company has incurred operating losses since its inception in 1995.  Losses are from costs incurred in operating and developing the Industrial Minerals Division, mineral exploration and mineral technology research.  Additional operating losses may occur in the future as a result of the continued operation of the MVQ and development of the Hammerstone Project.  However, the MVQ is expected to start generating increased revenues from aggregate sales in 2007.

Competitive Risk May Reduce the Company's Ability to Operate

Birch negotiates sale arrangements with its customers and has proven that its aggregate products are reliable and suitable for use in the oil sands industry.  Although the Company believes that competing aggregate resources in the Fort McMurray region are limited in both size and quality and, as a result, high market share assumptions have been made, Birch may have to compete with larger companies that have greater assets and financial and human resources, and which may be able to sustain larger losses than the Company to develop business.  Birch, and the economic viability of the MVQ and the Hammerstone Project may be negatively impacted if large new sources of aggregates and/or industrial minerals are located and developed.

10

---





Although no other quicklime and reagent limestone production operations exist in the region, one or more competitors currently supply lime products to the oil sands industry. Even with a quicklime and reagent limestone plant in the region, Birch expects it will face intense competitive pressures as it begins to bring its reagent limestone and lime products to market. In the face of this competition, Birch may need to lower prices for its products to reach its market share objectives.

Alternate Technologies May Reduce the Demand for the Company's Products

The use of limestone for aggregates and the use of quicklime and limestone as products for the treatment of air emissions and water treatment could be replaced by alternate technologies if the oil sands industry develops or locates more cost effective and efficient methods.  The rate of development of new technologies and the impact of their development on the Company's business cannot be determined.

Price Risks May Affect the Marketability of Products Produced and the Company's Financial Results

The industrial mineral industry is intensely competitive and even if commercial quantities of mineral reserves are developed, a profitable market may not exist for the sale of such reserves. Factors beyond the control of the Company may affect the marketability of any product produced. Significant price movements over short periods of time may be affected by numerous factors, including international economic and political trends, expectations of inflation, currency exchange fluctuations (specifically, the Canadian dollar relative to other currencies), interest rates and global or regional consumption patterns, speculative activities and increased production due to improved mining and production methods. The price of industrial minerals has a significant influence on the market price of the Company's shares and the Company's business activities.  The effect of these factors on the price of the Company's products cannot accurately be predicted.

Aggregate pricing in the Fort McMurray region is typically done on a spot or job basis and long-term contracts are uncommon.  Future prices and forecasting of revenues is difficult and unknown and future prices are outside the control of the Company.  If prices decline, the financial results of the Company will be adversely affected.

Customer Dependency May Reduce the Flexibility of the Company to Operate

Birch is reliant on the oil sands industry in the Fort McMurray area for the majority of its revenue.  Costs of transportation of aggregate are high relative to its cost of production and will limit the Company's ability to ship the product over longer distances.  Risks affecting oil sands companies, such as fluctuating oil and natural gas prices, fluctuations between the US and Canadian dollar, energy costs, labour shortages and capital cost overruns, could have a negative impact on Birch.  There is no guarantee oil sands companies will require the predicted volume of the Company's products.

11

---





Personnel Risks May Impact the Company's Ability to Carry Out its Operational Plans

At December 31, 2006, Birch had 27 full time and two part-time employees.  The Company relies on various other part time workers, contractors and consultants to assist in executing operations and providing technical guidance.

From time to time, Birch also utilizes the services of independent consultants and contractors to perform various specific professional services, particularly in the areas of engineering, environmental assessment, drilling, blasting, crushing, processing, analysis and research.  Although Birch believes that its relations with its employees, management, directors, consultants and contractors are satisfactory, there can be no assurance that they will remain with Birch for the immediate or foreseeable future.

Birch will be dependent on maintaining its key staff to explore and develop the mineral deposits on the Company's mineral properties.  As the Company continues to grow and expand its operations. it will be necessary to rely on workers, contractors and consultants in the local area. In northern Alberta, skilled labour shortages are common. There is uncertainty regarding the ability to retain and attract personnel to the project and should the Company not have adequate personnel, the project may not become operational or may not be economically viable.

Additionally, Birch is relying upon the good faith, expertise and judgment of the officers and directors of the Company to make appropriate decisions with respect to investments and operations.

Birch Will Require Additional Regulatory Approvals and Operating Permits

In the ordinary course of business, mining companies are required to seek regulatory approvals and operating permits from the federal, provincial and local governments for expansion of existing operations and the commencement of new operations.  Obtaining the necessary regulatory approvals and operating permits is a complex and time-consuming process involving numerous agencies and often involving public hearings and costly undertakings on the part of the Company.  The duration and success of regulatory and permitting efforts are contingent upon many variables outside the Company's control.  Environmental protection permitting, including the approval of reclamation plans, may increase costs and cause delays depending on the nature of the activity to be permitted and the interpretation of applicable requirements implemented by the permitting authority.  There can be no assurance that all regulatory approvals and operating permits will be obtained and, if obtained, that the costs involved will not exceed those previously estimated by the Company.  It is possible that the costs and delays associated with the compliance with such standards and regulations could become such that the Company could not proceed with the development or operation of the Hammerstone Project.  All regulatory approvals and operating permits for the MVQ were received in July 2005.

Title Risks May Result in Title Claims or Disputes

Birch is satisfied that it has good and proper right, title and interest in and to the mineral properties that are currently under development or in production.

Aboriginal peoples have claimed aboriginal title and rights to a substantial portion of western Canada.  Certain aboriginal peoples have filed a claim against the Government of Canada, the Province of Alberta, certain governmental entities and the RMWB (which includes the City of Fort McMurray, Alberta) claiming, among other things, aboriginal title to large areas of lands surrounding Fort McMurray, including the lands on which the MVQ and the Hammerstone Project and most of the oil sands operations in Alberta are located.  Such claims, if successful, could have a significant adverse effect on the oil sands bitumen producers and on Birch, the MVQ and/or the Hammerstone Project.

12

---





Regulatory and Environmental Requirements May Impact the Company's Ability to Operate

The Company operates in areas that are subject to governmental provisions regulating operations and development of mineral resources.  Birch Mountain may be constrained or forbidden to develop its plans or mandated operating guidelines may adversely affect the economic viability of the projects.  The Company holds mineral permits and leases issued by the Government of Alberta.

Birch is required by regulation to operate under certain environmental guidelines that are mandated by the Government of Alberta and the Government of Canada.  Additionally, public expectation of industry's environmental performance remains high. The Company has established environmental policies that it believes will allow it to operate effectively under the environmental guidelines.  Birch has and will continue to work with the regulators and local communities to address public environmental concerns. Regulatory agencies may impose operating limitations that could adversely affect Birch's revenues and/or the economic viability of a project.

Abandonment and Reclamation Costs and Regulations May Change

Birch is responsible for complying with terms and conditions of environmental and regulatory approvals and all laws and regulations regarding the abandonment of the site and reclamation of its lands at the end of its economic life, which abandonment and reclamation costs may be substantial.  A breach of such legislation and/or regulations may result in the imposition of fines and penalties, including an order for cessation of operations at the site until satisfactory remedies are made.  Abandonment and reclamation costs are estimates and since they will be a function of regulatory requirements at the time, costs of goods and services at the time and the value of the salvaged equipment may be more or less than the abandonment and reclamation costs. Birch is required to post bond or a letter of credit with Alberta Environment annually in an amount sufficient to reclaim the lands disturbed, thus managing the long-term reclamation liability.

Birch is Subject to Certain Mining Hazards

The business of mining is subject to certain types of risks and hazards, including environmental hazards, and industrial accidents.  Such occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damages, delays in mining, monetary losses and possible legal liability.  Any payments made with regards to such liabilities may have a material adverse effect on Birch's financial position.  The Company carries insurance to protect itself against certain risks of mining and processing to the extent that it is economically feasible but which may not be adequate.

Independent Reviews Provide No Assurance of Future Results

Although third parties have prepared reviews, reports and projections relating to the viability and expected performance of the MVQ and the Hammerstone Project, it cannot be assured that these reports, reviews and projections and the assumptions on which they are based will, over time, prove to be accurate.

There is a Possibility of Dilution to Present and Prospective Shareholders

Any transaction involving the issuance of additional Birch shares or securities may result in dilution, possibly substantial, to present and prospective holders of Common Shares.

13

---





Shareholders Rights Plan May Discourage Change in Control Transactions

Although the Company's shareholders rights plan (Rights Plan) is not intended to prevent a take over of the Company, to secure continuance of current management or the directors in office or to deter fair offers for the common shares of the Company, it may have the result of discouraging certain transactions by making such transactions impractical.  See Item 10B - Additional Information - Memorandum and Articles of Association.

Enforcement of Civil Liabilities by Present and Prospective Shareholders May be Adversely Affected

The enforcement by investors of civil liabilities under the federal securities laws of the US may be affected adversely by the fact that the Company is incorporated under the laws of Alberta, Canada, that the independent auditors who have audited the Company's financial statements and some or all of its directors and officers may be residents of Canada or elsewhere, and that all or a substantial portion of the Company's assets and said persons are located outside the US.  As a result, it may be difficult for holders of the Common Shares to effect service of process within the US upon people who are not residents of the US or to realize in the US upon judgments of courts of the US predicated upon civil liabilities under the federal securities laws of the US.

ITEM 4

INFORMATION ON BIRCH

A.

History and Development of Birch

Birch is an Alberta mineral exploration, development and production company formed under the provisions of the ABCA, by amalgamation of one of Birch's predecessors, also named Birch Mountain Resources Ltd., and its wholly owned subsidiary, Birch Mountain Minerals Ltd., on December 31, 1995.

Birch's head office and registered office are located at Suite 300, 250 - Sixth Avenue S.W., Bow Valley Square 4, Calgary, Alberta T2P 3H7, phone: (403) 262-1838, and Suite 1000, 400 Third Avenue S.W., Calgary, Alberta T2P 4H2, phone: (403) 232-9500, respectively.

Birch was founded in 1995 as a junior mineral exploration company.  Prior to 2000 it explored for precious metals, base metals and diamonds on properties in western Canada, the Yukon and Kalimantan, Indonesia.  Since 2000, the Company has expanded beyond conventional mineral exploration to include industrial minerals as well as research and development on naturally occurring precious and non-precious metal microparticles and nanoparticles.  Currently, Birch is only active in Alberta, Canada.

From early 2000 to 2002, the Company's work led to the development of methods to isolate and image, using high-resolution transmission electron microscopes, naturally occurring base and precious metal nanoparticles in rocks and process residues from the Athabasca region of northeast Alberta.  The commercial significance of these findings has not been determined.  A reliable method for measuring precious metal concentration has not yet been developed nor have independently verified and commercial methods of extraction been developed.  In December 2002, Birch was awarded US patent 6,494,932 entitled, Recovery of Natural Nanoclusters and the Nanoclusters Isolated Thereby, which covers processes for the recovery of natural nanoparticles from geological materials and their processed counterparts.

In June 2002, the Industrial Minerals Division was established to pursue opportunities arising from growing demand for industrial minerals in the Athabasca region of northeast Alberta.  The mineral rights held by the Company offer a compelling business opportunity due to their location close to current and planned oil sands facilities and the forecast increase in demand for aggregate and quicklime products from the oil sands industry and local infrastructure requirements.  Consequently, management has focused on this business opportunity over the past four and a half years.

Principal Capital Expenditures



The Company has invested principally in its mineral properties in the Athabasca over the last four years.  Over the past four years, $50.9 million has been invested in the MVQ and the Hammerstone Project and $19.4 million has been invested in mining equipment, software, hardware, leasehold improvements and miscellaneous office equipment.  There have been no significant divestitures or disposals over the past three years.

B.

Business Overview

Birch's principal operations are located north of Fort McMurray, Alberta, where the Company holds metallic and industrial mineral rights over an extensive portion of the Athabasca region in the heart of Alberta's expanding oil sands industry.  Birch does not own the mineral rights to the geological formations that contain the oil sands, but owns the mineral rights to the rocks that lie geologically beneath the oil sands. Since 2002, Birch has worked to commercialize the industrial mineral potential of limestone deposits that occur on its mineral holdings in the Athabasca region.

The Company operates separate divisions for industrial minerals, and mineral exploration and technology and the consolidated financial statements provide segmented information to identify expenditures in each. See Item 17 - Financial Statements.

Industrial Minerals

Muskeg Valley Quarry



In 2004, Birch formally applied to license a limestone quarry called the Muskeg Valley Quarry, situated within the Hammerstone Project.  This original application was to develop a starter quarry to supply crushed limestone aggregate to the local market.



In February 2004, Birch released an independent technical report on the MVQ project entitled, Muskeg Valley Project, Alberta  Independent Qualified Person's Review and Technical Report(the 2004 Technical Report).  The 2004 Technical Report was a preliminary assessment of the aggregate and calcinable limestone potential of the proposed MVQ.  It included a mineral resource estimate for calcinable and aggregate grade limestone, and a preliminary financial model. The 2004 Technical Report concluded that additional studies directed towards the construction and operation of a combined aggregate and quicklime facility were justified.



In March 2004, Birch filed an application and the supporting Environmental Impact Assessment (the MVQ Application) with the NRCB to develop, operate and reclaim a quarry and aggregate plant on its mineral leases adjacent to the Muskeg River. The Company received Approval NR-2005-1 from the NRCB on July 14, 2005, as authorized by an Order in Council from the Alberta Government the previous day, to construct and operate the MVQ and an aggregate plant.  During the last two quarters of 2005, site preparation work was completed that provided access to the MVQ.  Trees and overburden were cleared and a two-kilometre commercial access road was established.  The Company extracted limestone from surface exposures of its own limestone and used it in building the access road.  During the second quarter of 2006, aggregate meeting various product specifications was produced and the first sales from the MVQ were made.

15

---





Quarry development continued through 2006 in order to create the space necessary to operate efficiently and to provide access to the four limestone rock units present in the quarry.  Overburden was removed and pit materials were excavated and trucked to stockpiles.

The Hammerstone Project



As geological evaluation of the proposed MVQ progressed, testing of core samples from a 1996 drill hole and from new holes drilled in late 2002 and early 2003 confirmed the presence of high-calcium limestone suitable for producing quicklime. Quicklime is used in a range of industrial and environmental applications including flue gas desulphurization (FGD), which removes sulphur, mercury and other contaminants from atmospheric emissions from bitumen upgrading, and in treating water used in producing bitumen from SAGD in-situ projects.  Birch has determined that a number of oil sands operators are interested in a local source of quicklime and intends to pursue the business opportunity to establish a quicklime plant on its proposed quarry site.



In December 2004, the Company filed a Public Disclosure Document for the Hammerstone Project, a project involving a southward expansion of the MVQ and construction and operation of a quicklime plant.  The footprint of the starter MVQ lies wholly within and is continuous with the Hammerstone Project. Subsequently, in March 2005, Birch released a report conforming to NI 43-101 prepared by AMEC entitled Hammerstone Project Alberta:  Independent Qualified Person's Review and Technical Report(the 2005 Technical Report).  The 2005 Technical Report was based on AMEC's prefeasibility study of the Hammerstone Project.  The 2005 Technical Report is available on SEDAR at its website, www.sedar.com.



In February 2006, Birch filed a Project Update for the Proposed Hammerstone Project(the 2006 Project Update), describing an expanded limestone processing facility producing, in addition to quicklime: hydrated lime, milk of lime, recycled spent lime, cement and reagent limestone.   The update outlines the long-term development plan for the Hammerstone Project, which will include an initial lime plant and a cement plant constructed sequentially for more efficient use of project resources and alignment to local demand.  As the oil sands region expands, the Company will add additional lime kilns and product offerings to service the local demand requirements.  Birch's vision is to provide full-cycle products and services such as re-calcining spent lime and utilization of the gypsum by-product of flue gas desulphurization in site remediation.



In May 2006, Birch filed an application and environmental impact assessment with Alberta regulatory authorities for the Hammerstone Project (the Hammerstone Application). The area of the Hammerstone Application includes areas outside the area of the original MVQ Application. The proposed Hammerstone Project integrates the existing MVQ into an expanded quarry and aggregate plant, and adds a limestone-processing complex to produce limestone-based reagent products such as quicklime, hydrated lime and cement, as well as facilities for recycling spent lime and reclaiming solid residues generated when reagent limestone or lime are used to capture sulphur.



In August 2006, an updated independent NI 43-101 technical report entitled Hammerstone Project, Alberta: Qualified Person's Review and Technical Report (the 2006 Technical Report) was released, based on an update of the pre-feasibility study. The 2006 Technical Report was authored by AMEC Americas Limited and Phoenix Process Engineering, Inc.

The 2006 Technical Report describes and values the Hammerstone Project, which will ultimately cover an area of 1,608 hectares (4,408 acres). Aggregate processing facilities within the quarry will supply the needs of the oil sands industry, local infrastructure and municipal demand, as well as providing feedstock for the proposed limestone-processing complex. Limestone aggregate and reagent product average yearly sales are projected to reach an ultimate level of 19 Mt. The limestone-processing complex includes a quicklime plant that will be built in stages, projected to reach a production capacity of 1 Mt per year. Some of the quicklime will be further processed into hydrated lime in a plant with an ultimate capacity of 400,000 tonnes per year.

Details of the Muskeg Valley Quarry and the Hammerstone Project



Location and Mineral Interests



The Hammerstone Project, which encompasses the MVQ, is located within Birch's Athabasca mineral property, approximately 60 km north of the City of Fort McMurray near the hamlet of Fort McKay, Alberta.  The Athabasca mineral property is described in greater detail in Section 4(D).  The Company's mineral leases convey the rights to develop and produce metallic and industrial minerals, including limestone, while the mineral permits allow the Company to explore for these same minerals.



The Hammerstone Project is located at a site favourable for development, where limestone occurs at surface or is overlain by only thin layers of muskeg and overburden.  The development boundaries have been determined from geological, environmental, and economic considerations.  The western boundary is set back 200 metres from the Muskeg River, consistent with setbacks for wildlife habitat on adjacent oil sands leases.  The southern boundary is an area where limestone is known from the Company's geological mapping to be at or near surface. The eastern boundary has been placed where the overlying Cretaceous and Quaternary sediments are more than 20 metres thick, making commercial development less attractive due to the requirement to remove increasing amounts of materials overlying the limestone.  To the north, the limestone deepens beneath increasingly thick oil sands.



Future expansion of the Hammerstone Project is only possible to the south because in this area limestone lies at or near surface.  The Quarry of the Ancestors, the site of an ancient stone quarry, was discovered by Birch during its fieldwork.  This northeast corner of the project area has been set aside as an archaeological exclusion zone and due to it historical significance is under protective notation by the Government of Alberta.



In some areas, Birch's mineral leases overlap with oil sands leases of Shell Canada Ltd. (leases 90 and 13) and Syncrude Canada Ltd. (leases 22 and 30). These companies own the mineral and hydrocarbon rights to the oil sands but not to the underlying Devonian limestone. Birch has co-development agreements with Syncrude Canada Ltd. and a cooperation and information sharing agreement with Albian Sands Energy Inc. (a joint venture between Shell Canada Ltd., Chevron Canada, and Western Oil Sands Inc.) that provide for cooperative exploration, environmental planning, development, extraction, and production activities in areas of the overlapping leases.



Exploration



Birch has conducted mineral exploration of the Hammerstone Project since 1995, as described in the 2006 Technical Report.  Industrial minerals exploration began in 2002 and since this time Birch has conducted geological mapping and sampling, core drilling, geochemical analyses, bulk sampling, calcine testing and aggregate testing of limestone from the Hammerstone Project area.  Birch interprets the results of its surface and subsurface exploration programs to indicate that limestone from the Hammerstone Project is suitable for producing construction aggregates, quicklime, cement and other products used by the oil sands industry and in municipal and infrastructure construction.

Mineralization



Limestone is exposed at surface across the Hammerstone Project area or is present beneath a thin layer of muskeg or glacial overburden. The four limestone units selected for quarrying are accessible from surface and all together are up to 45 metres thick; additional limestone units are present below the lowest unit. The 2005 Technical Report identifies construction aggregate, concrete rock and quicklime as products to be made from limestone quarried at the Hammerstone Project.  Other products including reagent limestone, hydrated lime, milk of lime and cement were identified in the 2006 Technical Report.



Drilling



Birch has conducted drill programs within and near the Hammerstone Project, drilling 5 holes in 1996, 9 holes in 2002/2003 and 10 holes in 2004.  Additional drilling was done for hydrogeological testing in late 2005 and early 2006, but these holes were not cored. In 2006, Birch Mountain Resources drilled fourteen core holes at 13 locations. Twelve holes development holes were within MVQ and one exploration hole was drilled off-site at Poplar Creek, north of Fort McMurray. All core was logged by Birch staff. The MVQ drill results show continuity of stratigraphy with other drill data from across the Hammerstone Project. The 2006 drill core information was not available to be included in the 2006 Technical Report.



Sampling and Analysis



Birch conducted industrial mineral sampling programs across the Hammerstone Project area from 2002 to 2006; a total of 205 samples were collected and submitted for multi-element geochemical analyses.  In 2004, one 300 tonne bulk sample was collected from a surface pit for aggregate testing.  In 2005, drill core and excavated samples were tested to determine suitability for producing aggregate products. Drill core samples were taken over selected intervals and submitted for some or all of: aggregate testing, multi-element geochemical analyses and calcine testing. Birch concluded the results of its surface and drill core sampling programs demonstrated that construction aggregates, concrete rock and quicklime can be produced from the Hammerstone Projects.



Development of the Hammerstone Project



The details in this section for the Hammerstone Project are extracted from the 2006 Technical Report.



Quarry and Aggregate Plant Development and Operations



The MVQ was opened in December 2005; production began in the first quarter of 2006 with the first sale recorded in June 2006. Site preparation at the MVQ required clearing of trees and stripping and stockpiling of organic soils and overburden, construction of access roads, water diversion structures and wash ponds, and installation of a weigh scale and office. The quarry operates as a conventional drill-blast-crush operation.  Primary crushing plants are to be located near the rock face and fed by excavators or wheel loaders.  In-pit conveyors move rock from the primary crushers to secondary crushing plants.  Birch contracted a local quarry operator to operate the quarry in 2006, but has since assumed control of all quarry operations.  In 2006, Birch purchased a Hitachi EX1800 hydraulic shovel and a Cedarapids portable screening and crushing plant to meet increasing production demands.

Hammerstone Limestone Processing Complex



The current development plan for the Hammerstone Project was presented in the 2007 Hammerstone Project Update (the 2007 Project Update), filed with NRCB, Alberta Environment and the Alberta Board on February 27, 2007. The purpose of the 2007 Project Update was to inform regulators and regional stakeholders of Birch Mountain's optimized development plan for the Hammerstone Project, completed subsequent to filing the 2006 Technical Report in August 2006. The 2007 Project Update contains a revised start-up plan and staged capital expenditures that better align production capacity with demand projections. Quarry and aggregate plant operations for the Hammerstone Project remain unchanged from the 2006 Technical Report; however, plans for the limestone processing facilities have been revised and the early capital requirements reduced.



The capital savings are due to the adoption of flash calciners for initial quicklime production, beginning on-schedule in 2009. The modular flash calciners reduce project risk and enhance flexibility because they are less expensive and can be brought on stream as the market grows. Commissioning of the first rotary kiln is now scheduled for 2012, when projected quicklime and hydrated lime sales require its construction. Additional kilns for producing activated limestone and quicklime are scheduled for construction post-2012, as they are required to meet projected sales.



Capital Cost



The revised capital plan for Hammerstone presented in the 2007 Project Update was prepared using the quarry and aggregate plant information contained in the 2006 Technical Report, and new information and cost estimates prepared by Phoenix Process Engineering, Inc. for the limestone-processing complex.  The total capital cost estimate over the life of the project is now estimated to be $437 million (down from $536 million in 2006), which covers the direct field costs of executing four crushing plants, two flash calciners, one activation plant, three calcining plants, and the indirect costs associated with design, construction and commissioning.  Based on the 2007 Project Update, the estimated capital spending requirements for 2007 to 2011 are $108 million, down from the $229 million estimate in 2006 Technical Report.  Interest and financing costs during construction are excluded. The 2007 capital cost estimates for the Hammerstone Project are summarized in Table 4-1.

Operating Costs



The operating cost estimate is based on an owner-operated quarry, aggregate plant, and limestone processing complex, as described in the 2006 Technical Report. Costs have been calculated for the four main areas of mining, aggregate processing, calcining, hydrating, and site general and administration. Costs have been developed from data considered applicable to the Fort McMurray area. Table 4-2 shows the overall average operating cost anticipated for the Hammerstone Project over its planned 55-year life.  This estimate is categorized as Class 4, Prefeasibility Study level, with a nominal expected accuracy of +25%/-25%, as defined by the Association for the Advancement of Cost Engineering Cost Estimate Classification System.

Financial Analysis



In the 2006 Technical Report, AMEC performed an independent financial analysis on the Hammerstone Project using a discounted cash flow approach that assumed 100% equity financing using first quarter 2006 Canadian dollars. Projections for annual revenues and costs are based on data developed for the limestone quarry, aggregate and limestone processing plants, capital expenditures and operating costs. Estimated project cash flows were used to determine the pre- and after-tax net present value (NPV) and pre- and after-tax internal rate of return (IRR).



The pre-tax NPV of the Hammerstone Project presented in the 2006 Technical Report is C$1,669 million and the corresponding after-tax NPV is C$1,099 million (see Table 4-3), using a discount rate of 7.5%. The project's pre-tax IRR is estimated to be 36.3% and after-tax IRR is estimated to be 31.2%. The payback period is estimated at 5.9 years from first production in January 2006. The base-case quarry life is 55 years.



Table 4-3.

|----------------- | ------- | ----- | ----- | ----- | ----- | ----- | ----- | ---
|Pre-tax NPV       | $12,891 | 5,874 | 2,987 | 1,669 | 1,500 | 1,005 | 640   | 424
|Pre-tax IRR (%)   | 36.3%   |       |       |       |       |       |       |    
|After-tax NPV     | $8,613  | 3,913 | 1,981 | 1,099 | 986   | 655   | 411   | 266
|After-tax IRR (%) | 31.2 %  |       |       |       |       |       |       |    



Sensitivity analysis was performed by varying quarrying cost, process cost, product price and capital expenditure across a range of minus 20% to plus 20%. The cash flow model is most sensitive to changes in reagent limestone and aggregate product price, significantly less sensitive to mining costs, processing cost, and capital costs, and least sensitive to lime plant fuel cost.



Regulatory Status



On June 14, 2005, Birch received a decision report from the NRCB recommending approval of the MVQ. All final operating permits for the MVQ were received in the third quarter of 2005.

20

---





Birch filed the application and EIA for the Hammerstone Project on May 24, 2006 and released the 2007 Project Update to regulators and the public on February 27, 2007.  The Company expects to receive regulatory approval for the Hammerstone Project by the end of 2007 or early 2008.



Industry Overview



The Hammerstone Project is centrally located among numerous existing and planned bitumen extraction and upgrading projects in the Athabasca oil sands region of Alberta.  These projects and the associated infrastructure and municipal development, are expected to be the primary sources of demand for aggregate and reagent limestone products in the Fort McMurray region.



Demand for aggregate and reagent limestone products changes between the construction and production phases of bitumen extraction and upgrading projects. The construction phase requires a range of aggregate products including sub-base, base and construction aggregates for building roads and production facilities. In addition, asphalt aggregate is required for road building, concrete rock for building bridges, foundations and other structures, and low permeability shale pond liner to construct impermeable liners and surface water control structures. There is little or no demand for reagent limestone during the construction phase of oil sands projects.



Oil sands bitumen production facilities also require aggregate products for on-going mine and in situ project development, facilities maintenance and support, but in lower amounts than for construction.  Demand for reagent limestone products is driven by oil sands production where they are used for boiler feed-water treatment and for the control of sulphur emissions (desulphurization) where alternative fuels containing sulphur are used instead of natural gas. The reagent limestone products used for desulphurization are crushed limestone with a high calcium carbonate content for flue gas desulphurization (FGD) or fluidized bed combustion (FBC), and quicklime for FGD. Hydrated lime is used for water treatment at in-situ extraction and upgrading projects.



Supply and Demand  Aggregate



Current supplies of glacial aggregates in the Fort McMurray region are limited in both size and quality.  Poplar Creek is a gravel pit near Fort McMurray that has recently reached total depletion.  Susan Lake is another gravel pit that is believed to have less than 5 to 10 years' supply.  Although additional deposits have been found more recently, they are typically small and inadequate to assure a long-lived supply for construction and operation of oil sands mining and in situ projects.  Typically, aggregate deposits remaining in the region are sand-rich and contain ironstone, rendering them inappropriate for use in manufacturing concrete.



Based on information reported in the 2003 and 2004 Athabasca Regional Issues Working Group (RIWG) aggregate surveys, the average annual demand for road quality aggregate over the period 2003 to 2008 was 7.7 million tonnes and for concrete rock, 0.8 million tonnes. However, the RIWG aggregate surveys did not consider limestone, which was then being used by two major oil sands producers. The average annual limestone use for aggregate by these companies for 2001 to 2005 was 2.2 Mt.  Therefore, based on historical limestone aggregate use and RIWG reported data, the average aggregate demand is estimated to be 10.7 Mt annually, of which 8.5 Mt is estimated to come from glacial gravels.



Supply and Demand  Reagent Limestone and Quicklime



Quicklime and hydrated lime are not currently produced in the region and must be trucked in from plants located elsewhere. Competing sources of quicklime, their respective capacities and approximate road distances from the location of the proposed Hammerstone limestone processing complex are listed in Table 4-4.

1Data from government and industry sources.



Crushed limestone for FGD is used at the Tar Island power plant operated by TransAlta Utilities Ltd. on behalf of Suncor Energy Inc.  This limestone is believed to be obtained from Waterways Formation limestone exposed at the base of Suncor's original pit located on the west side of the Athabasca River, north of the Tar Island complex. No commercial sources of limestone, including high-calcium reagent grade limestone, currently exist in the region, other than Birch Mountain's Muskeg Valley Quarry and Hammerstone Project.  Although precise figures are not publicly available, Birch Mountain estimates that current use of reagent grade limestone in neutralizing sulphur emissions in the region amounts to approximately 250,000 to 300,000 tonnes per year.



No independent information has been found on the consumption of quicklime by the oil sands industry or other industries in the region.  Quicklime is used as a reagent in existing industrial and municipal water treatment facilities and by the pulp-and-paper industry.  Some information has been obtained from public disclosure of chemical reagents used in the oil sands industry.  Birch Mountain estimates that the current total market for quicklime and hydrated lime in northeast Alberta is 50,000 to 100,000 tonnes per year.  Much of the current demand is believed to be in the Cold Lake region, where water treatment is required for in situ steam-assisted recovery of bitumen from the oil sands.



Long-Term Demand and Sales Forecast



The long-term demand for limestone products in the Fort McMurray region is dominated by the construction and production requirements of the oil sands industry.  As described in the 2006 Technical Report, Birch Mountain contracted the Canadian Energy Research Institute (CERI) of Calgary, and Dr. Graham Davis, a mineral economist and professor at the Colorado School of Mines, to update the oil sands bitumen supply model developed be CERI and used in the 2005 Technical Report. The updated CERI/Davis model projected oil sands construction activity and bitumen production and upgrading from 2006 to 2070 and this formed the basis of Birch's most recent long-term demand and sales projections. The CERI/Davis model predicts that oil sands bitumen supply will continuously increase over the period 2006 to 2070, reaching nearly 12 million barrels per day by 2070.



Demand factors were derived for each of the limestone aggregate and reagent products scheduled for production at the Hammerstone Project. The demand factors are estimates of how much of each product is required for each barrel-per-day of oil sands capacity added by construction or each barrel-per-day of production capacity. Demand factors for aggregate and hydrated lime were independently derived from engineering design considerations. Demand factors for reagent limestone and quicklime were calculated using assumptions regarding the types and amounts of alternative sulphur-bearing fuels used by the oil sands industry over the period 2006 to 2060.

22

---





Forecast sales for limestone products were estimated by multiplying the CERI/Davis forecast oil sands construction and supply figures by the demand parameters and Birch's estimates of future market share.  For aggregate, market share estimates were adjusted to reflect competition from other known gravel deposits.  For quicklime and reagent limestone, market share estimates were made by distance weighting market share based on the closest alternative supplier at Exshaw, Alberta.  The most recently published sales estimates for all products are in the 2006 Technical Report.



Competitive Landscape



Studies by RIWG and the Alberta provincial government indicate that currently known sources of glacial gravels are insufficient to meet the long-term growth requirements of the oil sands industry.  Although additional deposits have been found recently, Birch believes they are small and inadequate to assure a long-lived supply for the construction and operation of oil sands mining and in-situ projects. Birch believes most aggregate deposits remaining in the region are sand-rich and contain abundant ironstone, rendering them inappropriate for use in making concrete and asphalt.



Based on all available information, Birch believes there will be little competition in the region for high value aggregates suitable for making concrete and asphalt. There is however more competition for lower grades of aggregate.  The prefeasibility study shows that competing sources of concrete rock are in limited supply and may be exhausted by 2011 and competing sources of lower quality A-grade and B-grade aggregates may not be totally exhausted until about 2025 to 2030.  However, Birch believes that as these competing deposits are depleted, operating costs to produce them will rise and, in the face of a long-term stable supply of aggregate from the MVQ and the Hammerstone Project, these deposits are likely to be shut-in before becoming totally exhausted.



Continuing Development of the Hammerstone Project



The Hammerstone prefeasibility update study, upon which the 2006 Technical Report is based, defined the geological, engineering, process, and financial criteria necessary to develop a quarry plan and mineral reserve estimate for the Hammerstone Project. The quarry will include and expand upon the existing Muskeg Valley Quarry and grow to cover an area of 1,608 hectares with a projected life of approximately 55 years. Quarrying will progress from north to south exposing the rock units required for production as needed. In the Hammerstone Application filed in May 2006, Birch is also seeking regulatory approval to construct and operate facilities to produce cement, recycle spent lime and store the solid by-product gypsum that is generated when limestone and/or lime are used to capture sulphur in combustion of alternative fuels. The Company expects to invest in excess of $500 million in developing the Hammerstone Project.



C.

Organizational Structure

Birch has two inactive, wholly owned subsidiaries, Dawson Bay Minerals Inc., incorporated pursuant to the Corporations Act (Manitoba) and Muskeg Valley Minerals Inc., incorporated pursuant to the ABCA.



The Company also has a 49% interest in a joint venture partnership operating as Hammerstone Products Limited.  The other joint venture partner is the Fort McKay First Nation who own the remaining 51% interest.  Hammerstone Products Limited will provide a marketing service on behalf of the MVQ in exchange for a marketing fee of $0.10 per tonne of limestone sold from the MVQ.



The work activities of the Company are organized under two main divisions:  Industrial Minerals and Mineral Exploration and Technology.

Property, Plants and Equipment

Office Space

Birch maintains its head office in Calgary, Alberta.  Executive, administrative and support staff work in the 7,972 square foot office space.  The rental commitment is $406,548 per year.

Core and Metallurgical Laboratories

The Company maintains secure lab and storage facilities in Calgary in an industrial area, for storage, logging and testing of drill core samples and for testing in relation to the mineral exploration and technology research work.  The rental commitment of these facilities is $37,200 per year.

Core drilled by Birch and core obtained from oil sands mining companies is shipped to Calgary for cutting, logging and sampling.  Drill core and samples are archived at the storage facility.  The laboratory is equipped for sample preparation, fire assay and wet chemical treatments.  Instrumental analyses are done offsite using rented analytical instruments at the University of Calgary or commercial analytical services.

Plant and Equipment

Birch owns office and computer equipment and small laboratory equipment in its offices and laboratories.  During 2006, a Hitachi EX1800 hydraulic shovel was purchased and is being used for selective excavation of limestone and should reduce the amount of blasting required.  Erection of a custom designed crushing and screening spread, acquired by the Company, is underway with delivery of the first pieces in September 2006. The Company expects this high-capacity crushing spread to be available to support aggregate sales in early 2007. Construction of scale house for weighing loaded trucks exiting the quarry was completed in late 2006.



The Company purchased three used rotary kilns, two pre-heaters and associated equipment in the second quarter of 2006 from a company in Addy, Washington and successfully dismantled and shipped all of the equipment to a laydown area cleared within the MVQ. All of the equipment will be stored at the quarry until the company receives regulatory approval to commence construction and operation of the limestone processing facilities.



Intellectual Property

In December 2002, Birch was granted US patent number 6,494,932 entitled, Recovery of natural nanoclusters and the nanoclusters isolated thereby.  Birch has also filed a similar patent application for protection under the International Patent Cooperation Treaty.  A divisional patent derived from the original patent application has been filed with the US Patent and Trademark Office.

Mineral Properties

Birch's mineral properties are located in northeast Alberta and they are collectively called the Athabasca mineral property. Since 2002, Birch's Industrial Minerals Division has explored the Athabasca mineral property with the intent of developing a commercial limestone producing operation.

Mineral Tenure in Alberta

Mineral Permits



Birch holds mineral permits issued by the Alberta Department of Energy.  Mineral permits have a 14-year term and convey the right to explore for metallic and industrial minerals.  Mineral exploration or assessment costs must be filed with the government every two years against an escalating work requirement ranging from $5.00 to $15.00 per hectare (approximately $2.00 to $6.00 per acre) for each 2-year assessment period.  Birch owns a 100% working interest in all of its mineral permits held in Alberta.  Some mineral permits are subject to a production royalty payable to the original mineral permit holder; Birch has the option to purchase most of these royalties for a fixed price.  A small minority convey a royalty right to the original mineral permit holder or its designees, with no right to purchase the royalty.  Mineral permits held in good standing may be converted to mineral leases any time prior to the expiry of their term.

Mineral Leases



Birch also holds mineral leases issued by the Alberta Department of Energy.  Mineral leases convey the right to develop and produce metallic and industrial minerals, subject to meeting development approvals.  Mineral leases have a renewable fifteen-year term, subject to payment of an annual rent of $3.50 per hectare ($1.42 per acre).  Mineral leases under production are automatically renewed at the end of their 15-year term.

In addition to Alberta mineral leases, Birch holds one Mineral Lease Agreement issued by Indian and Northern Affairs Canada (Table 4-5). This agreement conveys the mineral rights, including limestone, on lands included as part of a Treaty Settlement agreement between Canada and the Fort McKay First Nation.  The term of the agreement is 12 years.



Metallic and Industrial Mineral Permit-to-Lease Conversions



Birch has applied to have parts of certain permits that have reached the end of their respective ten-year terms converted to mineral leases.  The Province of Alberta formally recognizes their applications as permit-to-lease conversions.

Overlapping Mineral Rights



Ownership of minerals within the area of the Athabasca Oil Sands Mining Area, as defined by the Government of Alberta, is split between oil sands leaseholders and mineral lease or permit holders.  The Athabasca Oil Sands Mining Area covers all of Birch's mineral leases and many of Birch's mineral permits and permit-to-lease conversions.  Within this area, the oil sands leaseholders own the rights to all minerals that occur within the geological formations mined for oil.  Oil sands leaseholders do not own metallic or industrial mineral rights to either the overlying sedimentary rocks or the underlying Devonian limestone, which rights are owned by the metallic and industrial mineral permit or lease holders such as Birch.

Athabasca Mineral Property

As of December 31, 2006, Birch's Athabasca mineral property covered 378,201 hectares (934,533 acres). Annual rental payments on mineral leases of the Athabasca mineral property were $431,901 in 2006.  If current permit-to-lease conversions are received in 2007, net annual mineral lease rental payments will increase by $430,605. Lease rental permits will increase if the Company elects to acquire new mineral leases or decrease if existing low priority leases are allowed to expire. The Company continues its exploration and anticipates that the extent of its mineral properties will be reduced in the future to areas Birch believes to be the most prospective.

Rock Formations and Mineralization



Limestone is the principal exploration target on the Athabasca mineral property. The geology of the Athabasca mineral property is relatively simple, and is characterized by Precambrian basement overlain by about 300 meters of shallow westward dipping sedimentary rocks chiefly of Devonian and Cretaceous age. The Devonian rocks are predominantly marine dolostones, limestones and evaporites while overlying Cretaceous rocks are predominantly sandstones and shales, including oil-bearing sandstone, or oil sands, of the McMurray Formation. Structurally, the property is underlain by complexly folded and faulted Precambrian basement rocks, but the sedimentary rocks are largely undeformed, although fault zones with limited offset are present.  A large structure, the Bitumount Graben, has resulted in an estimated total downdrop of up to 200 meters of both sedimentary and basement rocks along numerous structures in the north-central part of the Athabasca mineral property.

Location and Access



The Athabasca mineral property is located in the Regional Municipality of Wood Buffalo (RMWB) in northeast Alberta, Canada.  The City of Fort McMurray is the urban and economic center of RMWB.  While the region covers 61,566 square km (23,771 square miles), most of itsresidents live in Fort McMurray, which has a population of 64,441. The total population of RMWB is 79,810 including an estimated 10,000 persons living in work camps located close to major oil sands construction projects. The First Nation community of Fort McKay is located in the central part of Birch's Athabasca mineral property.

Fort McMurray is located 435 km northeast of the provincial capital of Edmonton and can be reached by paved highways 2 and 63 or by regularly scheduled airline flights and bus service from Calgary and Edmonton. Fort McMurray is situated at the confluence of the Athabasca and Clearwater rivers. The larger oil sands mining plants are located approximately 45 to 100 km north of Fort McMurray.  Infrastructure north of Fort McMurray, in the vicinity of Fort McKay, is very good due to the presence of the large oil sands mining operations.  Fort McKay and the oil sands operations are accessed from Fort McMurray by provincial highway 63.  All major services, including goods and accommodation, air and helicopter service, vehicle and heavy equipment servicing and expediting can be obtained in Fort McMurray.  Infrastructure development is ongoing in Fort McMurray and the Athabasca Oil Sands Mining Area.

Near the Athabasca River, between Fort McMurray and Fort McKay, road access is good; once away from the river and further north, the number and condition of the roads decreases. A winter road exists from Fort McKay to Fort Chipewyan.  The Athabasca mineral property is accessible by road or all terrain vehicles. A high voltage power distribution line and high-pressure natural gas pipeline cross the Athabasca mineral property. Exploration activities are curtailed on certain exploration permits during moose and caribou calving season; this restriction occurs during spring break-up, which precludes land access for exploration activities at this time. Additionally, large area clearing is prohibited from May 1st to August 15th under the federal Migratory Birds Convention Act.

Mineral Title



Birch's currently active Athabasca mineral permits, permit-to-lease conversions and leases were either originally acquired from the Province of Alberta, or were acquired by purchase or option from other companies or individuals.  One mineral lease was obtained from Canada. At March 15, 2007 the Athabasca mineral property covered 380,136 hectares (939,315 acres), as outlined in Table 4-5 below:

Previous Exploration



Birch and others have previously explored the Athabasca mineral property for precious metals, diamonds and limestone.  Comprehensive details of all known prior exploration are included in the 2003 Technical Report. The 2003 Technical Report, filed in May 2003 in Canada and on June 3, 2003 as an exhibit to a Form 6-K filed with the SEC and is available in the Company's public documents at www.sedar.com and www.sec.gov.

In the period from 1993 to 1995, Birch and others explored for precious metals in areas that are now part of Birch's Athabasca mineral property.  Birch is unaware of any current precious metals exploration in the area.

In 1997-98, Birch explored with a joint venture partner for diamonds on its Athabasca mineral property.  No potentially diamond-bearing rocks were found during this exploration program.

Industrial Mineral Reserves



Mineral Reserves



Canadian and US regulations on disclosure of mineral reserves differ.  In Canada, mineral resources and reserves disclosure must conform to NI 43-101 of the Canadian Securities Regulators. In the US, Industry Guide 7 (Guide 7) of the US Securities and Exchange Commission (SEC) governs the disclosure of mineral reserves.



The limestone mineral resources and reserves for Hammerstone were first defined in the 2005 Technical Report under NI 43-101 in Canada. At that time the Canadian mineral reserves did not conform to the Guide 7 requirements. Subsequently, Birch brought the
quarry into production and since the second quarter of 2006 has sold limestone aggregates from the
quarry at market prices. On May 24, 2006, Birch submitted the Hammerstone Application containing all applications for required approvals of the Hammerstone Project that Birch reasonably expects will be received in late 2007. By establishing commercial viability through sales of aggregates to various end-users at market prices and with expectation of regulatory approval, the Hammerstone mineral reserves met Guide 7 requirements for
US purposes for qualification as a reserve as of May 24, 2006. The Hammerstone mineral reserves were updated in the 2006 Technical Report released in August 2006.



Limestone reserves are defined for each of the four geological units present in the proposed Hammerstone Quarry (2006 Technical Report). Aggregate resources and reserves are classified based on Canadian Standards Association (CSA) specifications for Concrete Materials (CSA Standard A23.1), Alberta Department of Transportation (AT) Standard Specifications for Highway Construction, and local oil sands industry specifications. For aggregates, tests included Los Angeles Abrasion (LAA) and Plasticity Index (PI). For concrete rock, test included the LAA and Magnesium Sulphate Soundness (MSS). Calcinable limestone reserves were defined based on the results of geochemical analyses of Unit 2, which contains an average 95.4% calcium carbonate and produces quicklime meeting user requirements (2006 Technical Report).



Limestone reserve estimates from the 2006 Technical Report are summarized in Table 4-6. The reserves listed meet the sales forecast feed requirements for the estimated 55-year life of the quarry.

|A Mineral Resource is a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth's crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction.  The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge.                                                                                                                                                                                                                                                             
|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.                                    
|A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit.  The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.               
|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.

ITEM 5

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

General

This discussion should be read in conjunction with Birch's consolidated financial statements.  Birch's consolidated financial statements have been prepared in accordance with Canadian GAAP, which differ from US GAAP.  For a discussion of these differences, see the notes to Birch's consolidated financial statements in Item 17 - Financial Statements.

A.

Operating Results

Years Ended December 31, 2006, 2005 and 2004



Prior to 2002, the Company focused on precious metals, base metals and diamond exploration and minerals technology development.  In 2002, the Company identified a business opportunity to develop a limestone quarry for aggregate sales and the manufacturing of quicklime for use by the oil sands industry.  As a result, since 2002 the Company has focused on advancing this limestone business opportunity and deferred funding for precious metal exploration and further technology development.  Birch intends to continue research and development of precious metals in the future.



The Company incurred a loss of $10,194,274 in the year ended December 31, 2006 (2005$4,641,818; 2004$2,887,057) and as at December 31, 2006, had an accumulated deficit of $17,484,901.



Income



The Company earned revenues from limestone sales of $1,540,564 in 2006, which includes an off-quarry limestone sale and cost of sales of $989,412 in 2006.   The Company did not have any sales in 2005 or 2004.



The Company earned interest income in 2006 of $498,028 and $332,568 in 2005.  In 2004, the Company's only source of revenue was a small amount of interest income, $48,190.



Expenses



In 2006, expenses totaled $11,243,454.

|Total Expenses                        | $ 11,243,454 | $ 4,974,386 | $ 2,935,247



Total expenses have risen in 2006 and 2005 as the Company moves forward with activities necessary for operations, including work necessary for the Hammerstone Project, the
South Haul Road ("SHR") application, the payment of professional fees related to long-term debt financing, compliance with the Sarbanes-Oxley Act and the independent 2006 Technical Report.  Total expenses increased $6,269,068 or 126%, of which $2,544,028 or 41% was related to
indirect quarry  costs, $1,600,375 or 26% was related to stock-based expenses, $727,644 or 12% was related to professional fees, $436,604 or 7% was related to shareholder services, $454,673 or 7% was due to increased salaries and benefits, $437,701 was related to interest and bank charges and $222,153 or 4% was related to amortization, accretion and depletion.  Office expense decreased $478,950 from 2005 due to an accrual of $516,286 in 2005 for the flow through shares. The remaining difference is related to development, operations and corporate activities for the development of the Company's limestone reserve in its Athabasca leases.

The increase in professional fees of $727,644 was due in part to $234,000 of fees paid for various credit facility and equipment financing contracts secured during 2006 and $242,891 in consulting fees paid for assistance in implementing compliance with Sarbanes-Oxley.  In addition, additional legal fees of $81,000 were paid for contract review and assistance with preparing and negotiating a legal settlement, and approximately $27,000 for auditing fees related to the restatement of prior years financial statements.

Total shareholder service costs increased $436,604 or 59% due mostly to an increase in Canada stock exchange costs of $306,545 or 185%.   The increase was due, in part, to increased filing fees paid to the relevant Canadian stock exchanges for the new debenture listing and the migration of Birch to the TSX for a total of $161,495.  Mail and transfer agent fees increased $146,530 due to the increased shareholder base in Canada. The increase in U.S. stock exchange costs was due mainly to higher U.S. exchange filing fees. Total marketing costs increased $75,690 due to increased expenditures on advertising in trade magazines and fees paid to the marketing joint venture with the Fort McKay First Nation.

Mineral Development Costs



In 2006, the Company spent a total of $32,987,591 of which $32,128,627 was capitalized.



|Mineral Development Costs                    | 2006         | 2005         | 2004

Industrial Minerals Costs



In 2006, Birch Mountain focused most of its resources on the opening and development of the MVQ.  These industrial mineral development costs can be broken down into four broad categories with the following estimated expenditures:

•

Site construction of $29.7 million paid to NORAMAC Ventures, an independent third party, for the excavation and stockpiling of surface overburden, development of the quarry pit, construction of equipment maintenance and lay down pads and a road and scale foundations, preparing part of the SHR and clearing the plant site;

•

Payments of $2.2 million to contractors and consultants for engineering, drilling, technical, environmental and regulatory services including any related materials;

•

An accrual of $679,000 for future site reclamation costs for the MVQ; and

•

Various administrative costs and salaries directly related to the MVQ or the Hammerstone Project.



Mineral Exploration and Technology Costs



Mineral exploration costs in 2006 were $858,964 as compared to $540,481 in 2005 and $762,371 in 2004.  The majority of these costs were land lease and permit payments to hold mineral rights. In 2006, Birch also initiated surface exploration on part of its Athabasca property north of the Hammerstone Project and adjacent to an announced oil sands development project.



The Company will make minor expenditures on mineral exploration and technology in order to hold patents and allow for some small level of future research work directed at evaluation of opportunities that may exist on mineral properties the Company holds in northeast Alberta outside of the Hammerstone Project.



B.

Liquidity and Capital Resources

Years Ended December 31, 2006, 2005 and 2004



Birch is a developing company with insufficient revenue as yet, to meet its yearly operating and capital requirements. The Company has historically raised funds necessary to conduct its business primarily through issuance of equity or debt.  The Company has incurred operating losses since its inception in 1995, and as of December 31, 2006, had an accumulated deficit of $17,484,901 (2005 - $7,290,627).  Losses are from costs incurred in the operation and development of the Industrial Minerals Division, exploration of mineral opportunities and research of mineral technology.  Results of operations have fluctuated from period to period and may continue to do so in the future. Additional operating losses may occur in the future as a result of the continued operation of the MVQ and development of the Hammerstone Project.  However, the MVQ is expected to start generating significant revenues from aggregate sales in 2007.

32

---





The Company has a working capital balance at December 31, 2006 of $9,064,787, a decrease of approximately $17.4 million from December 31, 2005.  The decrease is a result of the continued operation and development of the MVQ and Hammerstone Project as the Company spent a total of $32.1 million on mineral development, $0.9 million on mineral exploration, $2.5 million on initial quarry operations and purchased approximately $18.4 million in equipment during 2006.



During the year, Birch Mountain received $0.4 million (2005 - $4.3 million) from the exercise of stock options.  Additionally, the Company completed a public debenture financing for net proceeds, after costs of financing, of $33.2 million.  However, as the Company develops its limestone reserve, constructs the SHR and builds plant facilities, additional funds may be required.  The current estimates for capital for the MVQ and the initial phases of the Hammerstone Project, from 2007 to 2011, are $108 million, down from the $229 million in the 2006 Technical Report.  The Company is investigating project-specific financing for the longer-term development of the Hammerstone Project.



At present, the Company does not have sufficient working capital or cash flows to continue operations through 2007, without significant cash receipts from product sales from the quarry or short term financing through debt and/or equity.  The Company is actively quoting on several large aggregate construction projects scheduled for the first half of 2007.  The Company is also investigating debt alternatives and has completed a $15.5 million senior secured credit facility subsequent to December 31, 2006. The net proceeds from the financing will be used to fund the continued development and construction of the SHR recently acquired mineral permits and for general working capital purposes.



Project-specific financing for larger anticipated capital expenditures related to the Hammerstone Project may be available in the future.  To the extent the Company raises additional capital by issuing equity or convertible debt securities, ownership dilution to shareholders will result.



On-going commitments for capital resources relate largely to the maintenance of the mineral permits and leases granted to the Company by the Government of Alberta plus general operating leases and long term debt repayments.  At December 31, 2006, the Company held mineral leases, mineral permits and permit-to-lease conversions in the Athabasca region, covering an area of 380,136 hectares (939,315 acres).  Lease payments, along with associated fees in 2007 and years beyond will be approximately $432,000 annually, if Birch continues to hold all of its mineral leases into the future.    Mineral permits are maintained in good standing by making allowable exploration expenditures, although there is no obligation to do so.  Birch continuously evaluates its mineral permit holdings, relinquishing and/or acquiring permits as dictated by financial considerations as well as exploration and strategic priorities.



The Company issued convertible unsecured subordinated debentures having a face value of $34.5 million during the year.  The debentures were issued pursuant to a public offering and mature on December 31, 2011.  The debentures are convertible into common shares of the Company at any time prior to maturity at the option of the debenture holder at a conversion price of $3.30 per share.  In the year ended December 31, 2006 no debentures were converted into shares. The debentures bear interest at 6% and interest is payable semi-annually commencing on June 30, 2007.  Interest expense relating to the debentures will be approximately $2.07 million annually.

In 2006, the Company entered into a financing agreement with the Canadian Western Bank to finance a crushing and screening plant costing $6,922,050 plus goods and services taxes aggregating to 6%.  The original loan amount was $7,337,373 with an interest rate of 6.02%.  The loan is to be paid down over five years based on blended principal and interest payments of $1,379,184 per year.



Additionally, the Company financed a piece of quarry excavation equipment costing $1,235,000 under a lease arrangement.  Lease payments, consisting of principal and interest, will be $255,384 annually until August 2011 when the Company will have the option to purchase the equipment at its residual value of $200,000.



The Company is required to reclaim any land disturbances as detailed in its environmental approvals for the MVQ.  The Company estimated, based on costs provided by consulting engineers to the Company, the costs for third parties to return the MVQ to its reclaimed status as at December 31, 2006, would be $2.85 million.  For financial statement purposes, these costs have been discounted to $1.1 million.  Based on a preliminary estimate, the Company issued a letter of credit to Alberta Environment for $2.0 million for this reclamation work.  The Company must re-evaluate this annually and post additional security, as additional lands are disturbed by development, with Alberta Environment.  Also in connection with land disturbances, the Company was required to pay timber damage fees for immature trees removed, which had not reached commercial value.  The Company paid fees based on the permitted area of the MVQ even though not all the trees were cut during 2006.  A long-term asset has been recorded for the balance of amounts prepaid and this will be reduced as trees are actually cleared.



The Company estimated a future liability for the indemnification of shareholders for flow-through shares issued in 2003 and 2004, for which the Company was not able to incur qualifying expenditures.  The estimated liability and potential taxes payable, interest and penalties payable in the amount of $2.4 million has been accrued as a current liability.  During 2006, the Company amended its tax filing position and has reported the impact to the subscribers.  The actual liability will not be known until the Canada Revenue Agency reassesses each affected subscriber and the amounts are known by the Company.  The payment of the liability may stretch over many future years and could vary by up to 15%.



C.

Research and Development, Patent and Licenses

During the fiscal year ended December 31, 2000, the Company commenced research in novel mineral technology applications.  The research resulted in the filing of US and international patent applications.  It is the Company's policy that costs associated with such research are expensed in the period in which they are incurred.  During the fiscal years ended December 31, 2004, 2005 and 2006 the Company did not incur any related expenses.

Late in 2002, Birch was granted US patent number 6,494,932 entitled Recovery of Natural Nanoclusters and the Nanoclusters Isolated Thereby.  Birch has also filed a parallel patent application for protection under the International Patent Cooperation Treaty.

D.

Trend Information

Industrial Minerals



Our financial results are subject to changes in aggregate product prices.  In the past fiscal year, the general trend has been relatively flat with market sales prices consistent with those used in the 2006 Technical Report. Since 2005 there has been some upward pressure on the price of concrete rock due to its scarcity in the region, with prices rising to about $30 per tonne from $20 per tonne through this period.

E.

Off-Balance Sheet Arrangements

The Company has an operating line with a Canadian chartered bank that provides for an operating overdraft on the Company's chequeing account and is available for letters of credit.  At December 31, 2006, the Company has issued letters of credit under this agreement, in the amount of $2.0 million to Alberta Environment for future site reclamation liabilities.  As security for this operating line, the Company has pledged $2.0 million of short-term investments on deposit at the bank.  These particulars are disclosed in the Company's financial statements.

Compensation Committee

The Committee has a significant list of detailed responsibilities that are
outlined in its charter.

Compensation Policy



The Company's compensation policy has three components:  (i) base salary/consulting fee and benefits, (ii) the award of stock options and (iii) bonus.  The salary/consulting fee for each executive officer is determined having regard to such executive officer's responsibilities and performance.  The Compensation Committee undertakes a review of the compensation paid by similar companies in setting guidelines for the compensation of all Company's employees. The Compensation Committee has provided greater emphasis on the issuance of stock options to its executive officers as a major form of compensation.  In the view of the Compensation Committee, the issuance of stock options has had the advantages of encouraging growth in the Company and its share value, while reducing the cash expenditures required for executive salaries. The Company is currently a party to an employment contract with Douglas J. Rowe dated December 1, 1995, and approved by the shareholders of the Company on May 31, 1996.  Pursuant to the employment contract Mr. Rowe receives a salary of $108,000 annually and is entitled to receive stock options as determined from time to time by the Committee.  The Board of Directors of the Company has subsequently approved increases in Mr. Rowe's annual salary to $140,000 per annum, effective June 15, 2000, $164,800 effective January 1, 2004, $180,000 effective March 1, 2005 and $250,000 effective January 1, 2006.

E.

Share Ownership

See Item 6  Directors, Senior Management and Employees  Directors and Senior Management, above, for disclosure regarding share ownership and options of Birch directors and senior management.

The Board of Directors of the Company adopted the stock option plan of the Company on April 24, 2006, which was ratified by shareholders on May 25, 2006 (the Plan). The purpose of the Plan is to advance the interests of the Company by encouraging the directors, officers, employees and consultants of the Company, and of its subsidiaries, if any, to acquire shares in the Company, thereby increasing their proprietary interest in the Company, encouraging them to remain associated with the Company and furnishing them with additional incentive in their efforts on behalf of the Company in the conduct of its affairs. The Plan is administered by the Board of Directors of the Company or by a special committee of the Board of Directors, if appointed, from time to time (the Board).  Pursuant to the Plan, the Board may grant non-transferable options to purchase Common shares of the Company to directors, officers, employees and consultants of the Company and its subsidiaries and employees of a person or company which provides management services (excluding investor relations services) to the Company or its subsidiaries (Management Company Employees) (such persons hereinafter collectively referred to as Participants).  Under the Plan, stock options may be granted by the Company to officers, directors, employees, consultants and employees of a person or company which provides services to the Company, its subsidiary or affiliates of the Company from time to time up to a maximum of 10% of the Company's issued capital.  Any expiration or exercise of stock options during the terms of the Plan will allow the Company to re-grant the options on a continuous revolving and reloading basis.  Any increase in the issued and outstanding common shares will result in an increase in the available number of Common Shares issuable under the Plan, and any exercises of options will make new grants available under the Plan effectively resulting in a re-loading of the number of options available to grant under the Plan.

The price of options granted under the Plan shall not be less than the market price of the Common Shares at the time the option is granted. Options issued under the Plan may be exercised during a period determined by the Board, which cannot exceed five (5) years if listed on the TSXV or ten (10) years if listed on the TSX, and are subject to earlier termination upon the termination of the optionee's employment, upon the optionee ceasing to be a director and/or officer of the Company, or upon the retirement, permanent disability or death of an optionee.  The options are non-transferable, except in limited circumstances.  There is no agreement whereunder financial assistance will be provided by the Company to facilitate the purchase of shares under the Plan.

The number of securities issuable or reserved for issuance to insiders under all security based compensation arrangements cannot at any time exceed 10% of the issued and outstanding securities of the Company and the number of securities issued to insiders under all security based compensation arrangements within a one year period may not exceed 10% of the issued and outstanding securities.

The Plan permits the Board to amend, suspend, terminate or discontinue the Plan subject to any applicable regulatory approval. In particular, the Board may amend the Plan without shareholder approval if the amendment: (a) is for the purpose of curing any ambiguity, error or omission in the Plan or to correct or supplement any provision that is inconsistent with any other provision of the Plan; (b) is necessary to comply with applicable law or requirements of any stock exchange on which the common shares of the Company are listed; (c) is an amendment to the Plan respecting administration and eligibility for participation under the Plan; (d) changes the terms and conditions on which options may be granted pursuant to the Plan including the provisions relating to option price, vesting provisions and option period; (e) changes the termination provisions of an option or the Plan; (f) is an addition of a cashless exercise feature, payable in cash or securities which provides for a full deduction of the number of underlying securities from the Plan; or (g) is an amendment to the Plan of a housekeeping nature.  Notwithstanding the foregoing, no such amendment may have the effect of (h) amending the number of common shares issuable under the Plan; (i) adding any form of financial assistance by the Company for the exercise of any option; (j) resulting in a material or unreasonable dilution in the number of outstanding common shares or any material benefit to option holders; or (k) changing the class of eligible optionees to broaden the participation by insiders of the Company.

42

---





Without limiting the generality of the foregoing, but subject to any required regulatory approval of any regulatory authority or stock exchange, the Board may amend the option price, the option period (which in no event shall exceed ten (10) years from the date of grant) and the termination provisions of options granted pursuant to the Plan, without shareholder approval, provided that if the Board proposes to reduce the option price or extend the option period of options granted to insiders of the Company pursuant to the Plan, such amendments will require shareholder approval.

The TSX rules require shareholder approval of the Plan every three (3) years.

Memorandum and Articles of Association

The information under Item 14 - Description of Securities to be Registered contained in Amendment No. 4 to the Company's Registration Statement on Form 20-F dated April 25, 2001 is hereby incorporated by reference.

On March 28, 2005 the Board of Directors (the Board) of the Company adopted the rights plan of the Company (Rights Plan), which was implemented pursuant to a shareholders rights plan agreement (the Rights Plan Agreement) of the same date between the Company and Computershare Trust Company of Canada, as rights agent.  The shareholders of the Company approved the Rights Plan on May 12, 2005.  The purpose of the Rights Plan is, firstly, to protect shareholders of the Company from unfair, abusive or coercive takeover strategies, including the acquisition of control of the Company by a bidder in a transaction or series of transactions that does not treat all shareholders equally or fairly or that does not afford all shareholders an equal opportunity to share in any premium paid upon an acquisition of control.  Secondly, the purpose of the Rights Plan is to afford both the shareholders of the Company and the Board adequate time to assess an offer made for the Company and to pursue, explore and develop alternative courses of action in any attempt to maximize shareholder value.

The Rights Plan is not intended to deter a person from seeking to acquire control of the Company if such person is prepared to make a takeover bid pursuant to a permitted bid or competing permitted bid in accordance with the provisions of the Rights Plan.  The Rights Plan is intended to make it impracticable to acquire 20% percent or more of the outstanding voting shares of the Company other than by way of a permitted bid or a competing permitted bid.  This impracticability arises as a result of the fact that the Rights will substantially dilute the holdings of a person that seeks to acquire control of the Company other than by means of a permitted bid or a competing permitted bid.

There are no provisions in the By-laws regarding public disclosure of individual shareholdings.  Notwithstanding this, applicable Canadian securities legislation required certain public disclosure of persons owning or acquiring common shares in excess of 10% of a Company's issued and outstanding share capital.

Material Contracts

Birch has not entered into any material contracts (not made in the ordinary course of business) in the two years prior to the date of filing of this Form 20-F, except the Rights Plan. (See Item 10 Additional Information  Memorandum and Articles of Association).

D.

Exchange Controls

Canadian Investment Controls



There are no governmental laws, decrees or regulations in Canada relating to restrictions on the export or import of capital, or affecting the remittance of interest, dividends or other payments to non-residents.  Dividends paid to US residents, however, are subject to a 15% withholding tax or a 5% withholding tax for dividends if the shareholder is a corporation owning at least 10% of the outstanding voting shares of Birch pursuant to Article X of the reciprocal tax treaty between Canada and the US (See Item 10 - Additional Information - Taxation).

Except as provided in the Investment Canada Act(the ICA), which has provisions that restrict the holding of voting shares by non-Canadians, there are no limitations specific to the rights of non-Canadians to hold or vote the common shares under the laws of Canada or the Province of Alberta, or in the charter documents of Birch or its subsidiaries.

The ICA requires a person who is not a Canadian resident (a non-Canadian) making an investment, which would result in the establishment of a new Canadian business or which would result in the acquisition of control of a Canadian business (i.e. the gross value of the assets of which exceed a certain monetary threshold), to identify, notify, or file an application for review with the Investment Review Division of Industry Canada (IRD).  The notification procedure involves a brief statement of information about the investment on a prescribed form to be filed with the IRD by the investor within 30 days following implementation of the investment.  Specific investments are subject to review under the ICA.  It is intention of the IRD that investments requiring only notification will proceed without government intervention unless the investment is in a specific type of business activity related to Canada's cultural heritage and national identity.

If an investment is reviewable under the ICA, an application for review in the form prescribed is normally required to be filed with the IRD prior to the investment taking place and the investment may not be implemented until the review has been completed and the Minister of Industry (Minister) (the Minister responsible for Investment Canada) is satisfied that the investment is likely to be of net benefit to Canada.  The Minister has up to 75 days to make this determination.  If the Minister is not satisfied that the investment is likely to be of net benefit to Canada, the non-Canadian must not implement the investment or, if the investment has been implemented, may be required to divest himself of control of the business that is the subject of the investment.

In 1999, some of the powers, duties and functions of the Minister were transferred to the Minister of Canadian Heritage under Parts II to VI of the ICA as they relate to the prescribed business activities enumerated under paragraph 15(a) of the ICA, namely those that relate to Canada's cultural heritage or national identity (Cultural Activities) Cultural Activities include, among other things, the distribution or sale of books, magazines, film and video recordings and music recordings.  As a result, an application for review must be submitted to the Cultural Sector Review Division of the Department of Canadian Heritage (the CSRD) in respect of the acquisition of control of a Canadian business engaged in a Cultural Activity that exceeds the prescribed lower monetary threshold applicable to the acquisition of such Canadian businesses.

47

---





The Minister of Canadian Heritage's review, similar to the Minister's review, is based on the statutory threshold of net benefit to Canada.  CSRD is guided by certain policy statements regarding investments by non-Canadians in Canadian businesses engaged in certain Cultural Activities.  CSRD's policy statements address certain Cultural Activities at the production/publication, distribution and/or exhibition levels.

The following investments by non-Canadians are subject to notification under ICA:

1.

An investment to establish a new Canadian business; and

2.

An investment to acquire control of a Canadian business that is not reviewable pursuant to the ICA.

The following investments by non-Canadians are subject to review under the ICA:

1.

An investment is reviewable if there is an acquisition of control of a Canadian business and the asset value of the Canadian business being acquired equals or exceeds the following thresholds:

a.

For non-World Trade Organization (WTO) investors, the threshold is $5 million for a direct acquisition and $50 million for an indirect acquisition; the $5 million threshold will apply however for an indirect acquisition if the asset value of the Canadian business being acquired exceeds 50% of the asset value of the global transaction;

b.

Except as specified in paragraph (c) below, a threshold is calculated annually for reviewable direct acquisitions by or from WTO investors.  The threshold for 2007 is $281 million.  Pursuant to Canada's international commitments, indirect acquisitions by or from WTO investors are not reviewable;

c.

The limits set out in paragraph (a) apply to all investors for acquisitions of a Canadian business that:

i.

engages in the production of uranium and owns an interest in a producing uranium property in Canada;

ii.

provides any financial service;

iii.    provides any transportation services; or



iv.    is a cultural business.



2.

Notwithstanding the above, any investment which is usually only notifiable, including the establishment of a new Canadian business, and which falls within a specific business activity, including the publication and distribution of books, magazines, newspapers, film or video recordings, audio or video music recordings, or music in print or machine-readable form may be reviewed if an Order-in-Council directing a review is made and a notice is sent to the Investor within 21 days following the receipt of a certified complete notification.

With reference to 1 (a) above, generally speaking, an acquisition is direct if it involves the acquisition of control of the Canadian business or of its direct or indirect Canadian parent and an acquisition is indirect if it involves the acquisition of control of a non-Canadian direct or indirect parent of an entity carrying on the Canadian business.  No change of voting control will be deemed to have occurred if an investor acquires less than one-third of the voting control of a Canadian corporation.

With reference to 1(a) above, a WTO investor, as defined in the ICA, includes an individual who is a national of a member country of the WTO or who has the right of permanent residence in relation that WTO member, a government or government agency of a WTO member, a WTO investor-controlled entity, a corporation, a limited partnership, trust or other specified business organizations that is neither WTO-investor controlled or Canadian controlled of which two-thirds of its board of directors, general partners or trustees, as the case may be, are any combination of Canadians and WTO investors.

48

---





The ICA exempts certain transactions from notification and review, including, among others,



1.

An acquisition of voting shares if the acquisition were made in the ordinary course of that persons' business as a trader or dealer in securities;

2.

An acquisition of control of the company in connection with the realization of a security interest granted for a loan or other financial assistance and not for any purpose related to the provisions of the ICA;

3.

The acquisition of voting interests by any person in the ordinary course of a business carried on by that person that consists of providing, in Canada, venture capital on terms and conditions not inconsistent with such terms and conditions as may be fixed by the Minister; and

4.

Acquisition of control of the company by reason of an amalgamation, merger, consolidation or corporate reorganization, following which the ultimate direct or indirect control in fact of the company, through the ownership of voting interests, remains unchanged.



E.

Taxation

The following is a summary of the principal Canadian federal income tax considerations under theIncome Tax Act (Canada) and the regulations thereunder (collectively, the Tax Act, or ITA), generally applicable in respect of the holding and disposition of common shares.  The income tax consequences to any particular holder of common shares will vary according to the particular circumstances of each holder, including without limitation, the status of that holder as an individual, trust, corporation or member of a partnership, the jurisdiction in which that holder is subject to taxation and the place where that holder is resident.

This summary is based upon the Company's understanding of current provisions of the Tax Act and the Canada-United States Tax Convention (1980) (the Tax Convention) as at the date of this Form 20-F, of all specific proposals to amend the Tax Act publicly announced prior to the date hereof and of the current published administrative and assessing practices of the Canada Revenue Agency (the CRA).  Other than such proposed amendments, this summary does not take into account or anticipate changes in the law, whether by way of judicial decision or legislative action, nor any changes in the administrative or assessing practices of the CRA.  There is no assurance that any specific proposals to amend the Tax Act will be enacted as proposed or at all.  This summary does not take into account, or anticipate any provincial, territorial or foreign tax legislation or other considerations, which may differ from those consideration described herein.

This summary is applicable only to holders of common shares who, for the purposes of the Tax Act and the Tax Convention, are resident in the US, have never been resident in or deemed to be resident in Canada at any time while they have held common shares, deal at arm's length with and are not affiliated with, the Company, hold their common shares as capital property, do not carry on and are not deemed to carry on an insurance business in Canada, and will not use or hold or be deemed to use or hold the common shares in the course of carrying on business in Canada.  Common shares will generally be considered to capital property for purposes of the Tax Act unless they are held in the course of carrying on a business of trading or dealing in securities or acquired in a transaction which may be considered to be an adventure in the nature of the trade.  Special rules, which are not discussed in this summary, may apply to a US holder that is a corporation that carries on business in Canada and elsewhere.

This summary is of a general nature only and is not exhaustive of all Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any holder of common shares.  No opinion, with respect to taxation matters, was requested by the Company or provided by its auditors or legal counsel.  Each holder should consult his own tax advisor with respect to the income tax consequences applicable to him in his own particular circumstances.

49

---





Disposition of Common Shares



A non-resident of Canada will not be subject to tax under the Tax Act in respect of a capital gain realized upon the disposition or deemed disposition of a common share of the Company unless it constitutes taxable Canadian property under the Tax Act and the holder is not entitled to relief under the Tax Convention.  Such common shares will generally not be taxable Canadian property provided the holder thereof does not use or hold and is not deemed to use or hold such shares in connection with carrying on a business in Canada; such shares are not designated insurance property of the holder within the meaning of the Tax Act; that if the shares listed on a prescribed stock exchange under the Tax Act, the holder has not, either alone or in combination with persons with whom the holder does not deal at arm's length, owned or had the right to acquire 25% or more of the issued shares of any class or series of shares in the Company within 60 months preceding the date of disposition; such holder has not elected to treat such shares as taxable Canadian property upon ceasing to be a resident in Canada; and such shares were not acquired in a tax deferred exchange for property that was itself taxable Canadian property.

In the case of a non-resident holder to whom shares of the Company represent taxable Canadian property and who is resident in the US, relief from Canadian taxation may not be available under the Tax Convention in certain cases, including, without limitation, where the value of such shares is derived principally from real property situated in Canada.  Mineral exploration rights are generally considered to be real property for this purpose. Shareholders should consult with their tax advisors as to whether they will be afforded relief under the Tax Convention.

If common shares of the Company constitute taxable Canadian property and a holder is not afforded relief under the Tax Convention, a capital gain (or capital loss) will generally be realized to the extent that the proceeds of disposition received or deemed to be received exceed (or are less than) the aggregate adjusted cost base of such shares, net of any reasonable costs of disposition or deemed disposition.  One-half of any such capital gain (taxable capital gain) will be required to be included in income in the year of the disposition.  One half of the amount of any capital loss (allowable capital loss) may be deductible against certain taxable capital gains realized in that year in accordance with the provisions of the Tax Act.  Allowable capital losses for a taxation year in excess of taxable capital gains for that year may otherwise be available for deduction in other taxation years in accordance with the provisions of the Tax Act.

However, special rules apply if a non-resident of Canada or certain designated partnerships dispose of common shares of the Company to another corporation resident in Canada with which the non-resident does not deal or is deemed not to deal at arm's length and, immediately after the disposition, the Company is connected with the purchaser corporation within the meaning of the Tax Act.  Each holder should consult with their own tax advisor with respect to the income tax consequences of any such disposition applicable to them, in their own particular circumstances.

Dividends



In the case of any dividends paid or credited or deemed to be paid or credited to non-residents, the non-resident will be subject to tax on the gross amount of such dividends.  In the absence of relief under the Tax Convention, the Company will be required to withhold therefrom on account of tax, 25% of the amount of such dividend, and remit same to the Receiver General of Canada, and the net amount of the dividend will be paid to the non-resident holder.  In certain cases Article X of the Tax Convention reduces the rate of tax on dividends paid to residents of the US to 15% of the gross dividend (or 5% in the case of dividends paid to certain corporate shareholders that beneficially own at least 10% of the Company's voting shares).  Stock dividends received by non-residents from the Company are taxable in Canada as ordinary dividends.

50

---





Dispositions of common shares to the Company will generally result in a deemed dividend to the holder equal to the amount by which the consideration paid or deemed to be paid by the Company exceeds the paid-up capital of such shares.  The amount of such deemed dividend would be subject to withholding tax as described above.

US Federal Income Tax Consequences



The following is a discussion of possible US Federal income tax consequences, under US law, generally applicable to a US Holder (as defined below) of common shares of the Company.  This discussion does not address consequences peculiar to persons subject to special provisions of US Federal income tax law, such as those described below as excluded from the definition of a US Holder.  In addition, this discussion does not cover any alternative minimum, US state and local or foreign tax consequences.

The following discussion is based upon the Internal Revenue Code of 1986, as amended (the Code), Treasury Regulations, published Internal Revenue Service (IRS) rulings, published administrative positions of the IRS, and court decisions that are currently applicable, any of which could be materially and adversely changed, possibly on a retroactive basis, at any time.  In addition, the discussion does not consider the potential effects, both adverse and beneficial, of recently proposed legislation that, if enacted, could be applied, possibly on a retroactive basis, at any time.

Circular 230 Disclosure

Any tax statement made herein regarding any US federal tax is not intended or written to be used, and cannot be used, by any taxpayer for purposes of avoiding any penalties.  Any such statement herein is written in connection with the marketing or promotion of the transaction to which the statement relates.  Each taxpayer should seek advice based on the taxpayer's particular circumstances from an independent tax advisor.

As used herein, a US Holder includes a holder of common shares who is a citizen or individual resident (as defined under US tax laws) of the United States; a corporation created or organized in or under the laws of the US or of any political subdivision thereof; an estate the income of which is taxable in the US irrespective of source; or a trust if (a) a court within the US is able to exercise primary supervision over the trust's administration and one or more US persons have the authority to control all of its substantial decisions or (b) the trust was in existence on August 20, 1996 and has properly elected to continue to be treated as a US person.  This summary does not address the US tax consequences to, and US Holders do not include, persons subject to specific provisions of federal income tax law, including, but not limited to, tax-exempt organizations, qualified retirement plans, individual retirement accounts and other tax-deferred accounts, financial institutions, insurance companies, real estate investment trusts, regulated investment companies, broker-dealers, non-resident alien individuals, persons or entities that have a functional currency other than the US dollar, persons who hold common shares as part of a straddle, hedging or a conversion transaction, and persons who acquire their common shares as compensation for services.  This summary is limited to US Holders who own common shares as capital assets and who hold the common shares directly and not through an intermediary entity.

Distributions on Common Shares of the Company

Subject to the discussion below regarding passive foreign investment companies (PFICs), US Holders receiving dividend distributions (including constructive dividends) with respect to common shares of the Company are required to include in gross income (for US Federal income tax purposes) the gross amount of such distributions, to the extent that the Company has current or accumulated earnings and profits, as determined under US Federal tax principals.  This inclusion is done without reduction for any Canadian income tax withheld from such distributions.

Any Canadian tax withheld generally may be credited (subject to certain limitations) against the US Holder's US Federal taxable income.  (See more detailed discussion at Foreign Tax Credits below.)  To the extent that distributions exceed current or accumulated earnings and profits of the Company, they will be treated first as a return of capital up to the US Holder's adjusted basis in the common shares and thereafter as a gain from the sale or exchange of the common shares.  Dividends received by non-corporate US Holders may be subject to US federal income tax at lower rates (generally 15%) than other types of ordinary income in taxable years beginning before 2011 if certain conditions are met.  These conditions include the Company not being classified as a PFIC, it being a qualified foreign corporation, the US Holder's satisfaction of a holding period requirement, and the US Holder not treating the distribution as investment income for purposes of the investment interest deduction rules.  In the case of US Holders that are corporations, such dividends generally will not be eligible for the dividends received deduction.

Foreign Tax Credit

A US Holder who pays (or has withheld from distributions) Canadian income tax with respect to the common shares of the Company may be entitled, at the option of the US Holder, to either a deduction or a tax credit for such foreign tax paid or withheld, at the option of the US Holder.  Generally, it will be more advantageous to claim a credit because a credit reduces US Federal income taxes on a dollar-for-dollar basis, while a deduction merely reduces the taxpayer's income subject to tax.

This election is made on a year-by-year basis, and applies to all foreign income taxes (or taxes in lieu of income tax) paid by (or withheld from) the US Holder during the year.  There are significant and complex limitations which apply to the credit, among which is the general limitation that the credit cannot exceed the proportionate share of the US Holder's US income tax liability that the US Holder's foreign source income bears to his/her or its worldwide taxable income.

In the determination of the application of this limitation, various items of income and deduction must be classified into foreign and domestic sources.  Complex rules govern this classification process.

In addition, this limitation is calculated separately with respect to specific classes or baskets of income; foreign taxes assigned to a particular class of income generally cannot offset United States tax on income assigned to another class.  For tax years beginning after 2006, there are two classes of income, passive category income and general category income for United States foreign tax credit purposes.  For tax years of US Holders beginning after October 22, 2004, unused foreign tax can generally be carried back one year and forward ten years.

The availability of the foreign tax credit and the application of the limitations with respect to the foreign tax credit are fact specific, and US Holders should consult their own tax advisors regarding the foreign tax credit rules.

52

---





Currency Fluctuations

For United States federal income tax purposes, the amount received by a US Holder as payment with respect to a distribution on, or disposition of, common shares, if paid in Canadian dollars, will be the US dollar value of the payment, regardless of whether the payment is later converted into US dollars.  In such case, the US Holders may recognize additional ordinary income or loss as a result of currency fluctuations between the date on which the payment is made and the date the payment is converted into US dollars.

Disposition of Common Shares of the Company

Subject to the PFIC discussion below, a US Holder will recognize gain or loss upon the sale of commons shares of the Company equal to the difference, if any, between the amount of cash plus the fair market value of any property received, and the US Holder's tax basis in the common shares of Company.

This gain or loss will be capital gain or loss if the common shares are a capital asset in the hands of the US Holder, which will be a short-term or long-term capital gain or loss depending upon the holding period of the US Holder.  Under present law, a non-corporate US Holder generally is eligible for a maximum 15% US Federal income tax rate, subject to the PFIC discussion below, for net long-term (held more than one year) capital gains.  Gains and losses are netted and combined according to special rules in arriving at the overall capital gain or loss for a particular tax year.  Deductions for net capital losses are subject to significant limitations.

US Anti-Deferral Regimes - Passive Foreign Investment Company (PFIC) Regime

The PFIC rules may apply to US Holders if the Company, or an entity directly or indirectly owned by the Company (Related Entity), derives 75% or more of its gross income from certain types of passive income (generally, interest, dividends, rents, royalties and the like), or if the average value during a taxable year of the Company or the Related Entity's passive assets (generally, assets that generate passive income) is 50% or more of the average value of all assets held by the Company or the Related Entity.  If the Company or a Related Entity is classified as a PFIC, a US Holder will be subject to increased tax liability in respect of gain recognized on the disposition of common shares or upon the receipt of certain distributions, unless the US Holder makes an election to be taxed currently on his, her or its pro rata portion of the Company's income and gain, whether or not such income or gain is distributed in the form of dividends or otherwise, and the Company provides certain annual statements which include the information necessary to determine inclusions and assure compliance with the PFIC rules.  As another alternative to the foregoing rules, a US Holder may make a mark-to-market election to include in income each year as ordinary income an amount equal to the increase in value of the Common shares for that year or to claim a deduction for any decrease in value (but only to the extent of previous mark-to-market gains).

Neither the Company nor any Related Entity can give any assurance as to its status as a PFIC for the current or any future year, and offers no opinion or representation of any kind with respect to the PFIC status of the Company or any Related Entity.US Holders should consult their own tax advisors with respect to the PFIC issue and its applicability to their particular tax situation.

ITEM 11

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company has not entered into any activities in derivative financial instruments or derivative commodity instruments. The Company's financial assets are in the form of cash and cash equivalents and are held in short term interest-bearing deposits at institutions with high credit quality ratings.

As a Canadian Company, Birch's cash balances are kept primarily in Canadian funds, revenues are negotiated in Canadian dollars and expenses are predominately in Canadian dollars. The Company does have limited exposure to foreign exchange risk, but this is restricted to payment of current trade accounts payable in US Dollars where most of the Company's cash assets are denominated in Canadian Dollars. The Company maintains a bank account in US Dollars from payments received in US Dollars to pay these trade accounts. Therefore, the Company believes it is exposed to only minimal exchange rate risk. The Company considers the amount of risk to be manageable and does not currently, nor is likely in the foreseeable future, conduct hedging to reduce its exchange rate risk.

    Executive Officer and the Chief Financial Officer, and review that these
    reports do not contain an untrue statement of a material fact or omit to
    state a material fact required to be stated therein or necessary to make the
    statements therein not misleading;
  periodically review past disclosures contained in public filings and other
    public information and advise whether any updates or corrections are
    appropriate; and
  evaluate and advise on the effectiveness of the Company's internal and
    disclosure controls and procedures, including the steps that it deems
    necessary or desirable to effect compliance with those procedures.There are inherent limitations as to the effectiveness of any system of
disclosure controls and procedures, including the possibility of human error and
circumvention or overriding of the controls or procedures. It should be also be
noted that the Company's internal controls and procedures will not prevent or
detect all errors and fraud. A control system, no matter how well conceived or
operated, can provide only reasonable, not absolute, assurance that the
objectives of the control system are met. Accordingly, even effective disclosure
controls and procedures can only provide reasonable assurance of achieving their
control objectives. Consequently, management applies its judgment in evaluating
the cost-benefit relationship of possible controls and procedures.
The Chief Executive Officer and the Chief Financial Officer, together with
management, have evaluated the effectiveness of the Company's disclosure
controls and procedures and internal controls over financial reporting as of
December 31, 2006, and identified the following material weaknesses:
1.     Design weaknesses relating to controls and processes
due to (i) insufficient communication of the Company's policies and Code of the
Conduct to employees of the Company, (ii) a lack of a formal management override
policy relating to the Company's policies and Code of Conduct, and (iii)
monitoring process to confirm responsibility of financial results. Management
believes that weaknesses in these areas aggregated to a material weakness for
effective company level controls and require more formalization of existing
controls and processes.
2.     Design weaknesses related to the processes and
communication of operational information, which may have a financial
implication, to accounting and finance, in a timely manner.
3.     Control design weaknesses relating to a lack of
segregation of various accounting duties resulting from the small size of the
Company's accounting department, lack of certain formal accounting procedures
for the documentation of various approvals and reviews, as well as, control
weaknesses inherent in accounting software employed by the Company which is not
a sophisticated enterprise application.
Solely as a result of these material weaknesses, we concluded that our
disclosure controls and procedures were not effective as of December 31, 2006.
The Company is experiencing rapid growth and has implemented new policies and
processes to address the design weaknesses described above. During fiscal 2006,
the Company undertook a comprehensive assessment of its internal control over
financial reporting by conducting regular reviews and audits to identify
weaknesses and to ensure that an environment of continuous improvement becomes a
part of the culture of the Company. The Company further intends to
systematically and regularly provide and explain its policies and Code of
Conduct to employees. In addition, the Company intends to introduce additional
internal control procedures during the next fiscal year to ensure that
appropriate internal control over financial reporting is in place and that such
controls keep pace with the growth of the Company. The Company has and will
continue to implement improvements in segregation of accounting duties, increase
controls for review, approval and documentation, and will upgrade during 2007
its accounting software to address inherent limitations.
Other than with respect to the identification of these material weaknesses,
there was no change in our internal control over financial reporting during the
year ended December 31, 2006, that materially affected, or is reasonably likely
to materially affect, our internal control over financial reporting.

|Report of Management         





MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING



The management of Birch Mountain Resources Limited is responsible for establishing and maintaining adequate internal control over financial reporting. The Securities and Exchange Act of 1934 in Rule 13a-15(f) and 15d-15(f) defines this as a process designed by, or under the supervision of, the Company's principal executive and principal financial officer and effected by the Company's Board of Directors, management and other personnel, 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 and includes those policies and procedure that:



•

Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

•

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 consolidated financial statements.



Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.



The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2006. In making this assessment, the Company's management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.



The Chief Executive Officer and acting Chief Financial Officer, together with management, have reviewed the design and effectiveness of the Company's internal control over financial reporting as part of Section 404 of the U.S. Sarbanes-Oxley Act of 2002 and have concluded that there were no changes in our internal control over financial reporting that occurred during 2006 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting other than the changes made to
address the following material weaknesses:



1.

Design weaknesses relating to controls and processes due to (i) insufficient communication of the Company's policies and Code of the Conduct to employees of the Company, (ii) a lack of a formal management override policy relating to the Company's policies and Code of Conduct, and (iii) monitoring process to confirm responsibility of financial results.  Management believes that weaknesses in these areas aggregated to a material weakness for effective company level controls and require more formalization of existing controls and processes.

2.

Design weaknesses related to the processes and communication of
operational information, which may have a financial implication, to accounting
and finance, in a timely manner.

3.

Control design weaknesses relating to a lack of segregation of various accounting duties resulting from the small size of the Company's accounting department, lack of certain formal accounting procedures for the documentation of various approvals and reviews, as well as, control weaknesses inherent in accounting software employed by the Company which is not a sophisticated enterprise application.

|Report of Management         



TO THE SHAREHOLDERS OF BIRCH MOUNTAIN RESOURCES LTD.



Management is responsible for the preparation of the financial statements and for the consistency therewith of all other financial and operating data presented in this Annual Report. In preparation of these financial statements, management selects appropriate accounting policies and uses its judgment and best estimates to report events and transactions as they occur. Management has determined such amounts on a reasonable basis in order to ensure that the financial statements are presented fairly, in all material respects.



Management maintains a system of internal controls to ensure, on a reasonable and cost effective basis, that the Company's assets are safeguarded and to facilitate the preparation of relevant, reliable and timely financial information. Management has the responsibility for preparation and fair presentation of the accompanying financial statements, including the financial processes that give rise to such consolidated financial statements. This responsibility includes selecting appropriate accounting principles and making objective judgments and estimates in accordance with Canadian generally accepted accounting principles and providing a reconciliation to generally accepted accounting principles in the United States.



It is the responsibility of the Audit Committee and the Board of Directors to review the financial statements in detail with management prior to their approval of the finan­cial statements for publication.   In addition, the Audit Committee meets regularly with management and the external auditor to review accounting policies, financial reporting and internal controls.   The Audit Committee is comprised of three independent and financially literate directors.  The Audit Committee is responsible for the compensation of the external auditor and pre-approves their retention for the appointment and any such fees related to non-audit services.



External auditors appointed by the shareholders have examined the financial statements.  Their report is attached to the audited consolidated financial statements that follow. The Audit Committee has reviewed these statements with management and the auditors and has reported to the Board of Directors.  The Board has approved the financial statements.

|Consolidated Balance Sheets  





To the Shareholders of

Birch Mountain Resources Ltd.





We have audited the consolidated balance sheets of Birch Mountain Resources Ltd. as at December 31, 2006 and 2005, and the consolidated statements of loss and deficit, and cash flows for each of the years then ended.  These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these financial statements based on our audits.



We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform an audit to obtain reasonable assurance whether the financial statements are free of material misstatement.  An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting.  Accordingly, we express no such opinion.  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 audit provides a reasonable basis for our opinion.



In our opinion, these financial statements present fairly, in all material respects, the consolidated financial position of Birch Mountain Resources Ltd. as at December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the years then ended in conformity with Canadian generally accepted accounting principles.



The financial statements as at December 31, 2004 and for the year
then ended were audited by another auditor who expressed an opinion without reservation on those statements in their report dated February 25, 2005 (except for notes 3 and 8, which are as of July 25, 2005, and note 19, which is as of November 10, 2006).

COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. 
REPORTING DIFFERENCES

In the United States, reporting standards for auditors require the addition of
an explanatory paragraph, following the opinion paragraph, when the financial
statements are affected by conditions and events that cast substantial doubt on
the Company's ability to continue as a going concern, such as those described in
note 1 to the consolidated financial statements. Our report to the shareholders
dated March 29, 2007 is expressed in accordance with Canadian reporting
standards which do not permit a reference to such events and conditions in the
auditors' report when these are adequately disclosed in the financial
statements.

|For the years ended December 31, 2006, 2005 and 2004



1.

Nature of operations and going concern uncertainty



Birch Mountain Resources Ltd. (the Company), incorporated under the jurisdiction of the Business Corporations Act of Alberta, is exploring and developing its mineral leases and permits and operating a limestone quarry on its mineral leases, in Northern Alberta.  At inception, the efforts of the Company were focused on exploration of precious metals and research into precious metals technology.  However, over the past four and a half years its focus has been on the development of its industrial minerals.  The mineral rights of the Company are to develop, extract and sell limestone products. The Company has two projects in its industrial minerals division, the Muskeg Valley Quarry and the Hammerstone Project, both of which are development of and commercialization of the limestone contained on the Company's mineral leases.  The Muskeg Valley Quarry is a limestone aggregate quarry approved by the government regulators.  The Hammerstone Project is a planned quarry expansion and quicklime and cement plants.  The Company must comply with conditions of the regulatory approvals such as to monitor ground water, report extraction and pay royalties thereon and the reclaim the site at the end of production.



As at December 31, 2006, the Company had incurred a net loss of $10.2 million for the year then ended and had an accumulated deficit of $17.5 million. The Company's ability to continue as a going concern is uncertain and dependent upon its ability to obtain additional financing and/or achieve profitable operations. The Muskeg Valley Quarry is operational and the Hammerstone Project is considered to be in the development stage.  The Company is currently exploring a range of strategic opportunities. The outcome of this review cannot be predicted at this time. If the Company is unable to obtain adequate additional financing, management may be required to curtail the Company's operations.



On August 2, 2006, the Company released an independent technical report, which indicates the existence of a limestone quarry in the Fort McMurray area and reports an estimated value for the mineral reserves significantly in excess of the current carrying value of the mineral properties.  The financials have been prepared on a going concern basis, which presumes the realization of assets and settlement of liabilities through the normal course of operations.  The financials do not include any adjustments relating to the recoverability and classification of recorded assets or liabilities that maybe necessary should the Company be unable to continue as a going concern. The ability of the Company to continue as a going concern is dependant upon the existence of economically recoverable reserves, securing and maintaining title and beneficial interest in the properties, and the ability of the Company to obtain the necessary financing or cash flow to continue the development and operation of its mineral properties.

2.

Significant accounting policies (continued)



(c)

Use of estimates



The preparation of the consolidated financial statements in conformity with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period.  Actual results could differ from those reported.



Significant areas requiring the use of management estimates include estimates related to the determination of impairment of mineral exploration costs, reclamation obligations and determination of qualifying renouncements and the assumptions used in calculating stock option compensation expense.  These estimates are reviewed periodically and, as adjustments become necessary, they are reported in earnings in the periods in which they become known.



(d)

Revenue recognition



The Company recognizes revenue on the sale of its products when delivery occurs.



(e)

Cash and cash equivalents



Cash and cash equivalents include balances with Canadian chartered banks and investment certificates with maturities of three months or less at the date of purchase.  Cash equivalents are carried at cost, plus accrued interest, which approximates market value.



(f)

Inventory



Inventory is valued at the lower of average cost and net realizable value.  Average cost includes direct materials, direct labour, operational overhead expenses and depletion.



(g)

Property, plant and equipment



Property, plant and equipment are recorded at cost.  Assets are not amortized until they are put into use. Amortization is provided over their estimated useful lives, using the following methods and rates:

|                       | Method            | Annual Rate
|---------------------- | ----------------- | -----------
|Equipment              | Declining balance | 20%        
|Computer               | Declining balance | 30% - 100% 
|Leasehold improvements | Straight line     | 5 years    
|                       |                   |            



(h)

Mineral properties



The Company expenses mineral exploration costs in the year they are incurred, unless on a property-by-property basis the deferral criteria are met and it is probable that they will be recoverable from the future operations of the related project. When it is determined that a mining property can be economically developed as a result of established proven and probable reserves, the costs of further exploration and development to further delineate the reserve on such a property are capitalized.  Determination as to the establishment of proven and probable reserves is based on results of technical reports, which indicate whether a property is economically feasible.  These expenditures are depleted according to the unit-of-production method.  This method allocates the costs of these assets to each accounting period.  The amount of depletion is measured by the portion of the mines' economically recoverable proven reserves which are recovered during the period..

|Notes to the Consolidated Financial Statements      
|For the years ended December 31, 2006, 2005 and 2004



2.     Significant accounting policies (continued)





The Company reviews its capitalized costs on a mineral property under development on an annual basis, or more frequently if events warrant, and will recognize an impairment in value on each property to the extent that the recoverable amount based on estimated future cash flows on a discounted basis is less than the carrying amount of the property.  Future cash flows are estimated based on future recoverable minerals based on proven and probable reserves.  Future cash flow estimates will also incorporate expected sales prices for recoverable minerals, costs of production and taxes, capital expenditures and development costs, remediation and closure costs, utilizing assumptions from its feasibility studies and subsequent engineering, geological or financial information where operations have not yet commenced.



Management's estimates of mineral prices, recoverable proven and probable reserves and operating and capital costs are subject to certain risks and uncertainties, which may affect the recoverability of mineral property costs.  Although management has made its best estimate of these factors, it is possible that changes could occur in the near term, which could adversely affect the future net cash flows to be generated from the properties or the financial position of the Company.



(i)

Asset retirement obligation

The Company recognizes a liability for the fair value of environmental and site restoration obligations when the obligations are incurred and the fair value can be reasonably estimated.  The fair value of the obligations is based on the estimated cash flow required to settle the obligations discounted using the Company's credit adjusted risk-free rate.  The fair value of the obligation is recorded as a liability with the same amount recorded as an increase in capitalized costs.  The amounts included in capitalized costs are depleted using the unit-of-production method. The liability is adjusted for accretion expense representing the increase in the fair value of the obligations and amortized over the mines useful life.  The accretion expense is recorded as an operating expense through periodic charges to earnings.  The Company's estimate of reclamation costs could change as a result of changes in regulatory requirements and cost estimates.



(j)

Capital lease obligations



Leases meeting certain criteria are accounted for as capital leases. The imputed interest is charged against income. If the lease contains a term that allows ownership to pass to the Company or there is a bargain purchase option the capitalized value is depreciated over the estimated useful life of the related asset.  Obligations under capital leases are reduced by rental payments net of imputed interest.



(k)

Future income taxes



The Company follows the liability method of accounting for income taxes.  Under this method, future income tax assets and liabilities are recorded based on temporary differences between the carrying amount of balance sheet items and their corresponding tax bases.  In addition, the future benefits of income tax assets, including unused tax losses, are recognized, subject to a valuation allowance, to the extent that it is more likely than not that such future benefits will ultimately be realized.  Future income tax assets and liabilities are measured using substantively enacted tax rates and laws expected to apply when the tax liabilities or assets are to be either settled or realized.

2.     Significant accounting policies (continued)



(l)

Stock-based compensation and contributed surplus



The Company uses the fair value method of accounting for all stock options granted whereby stock-based compensation on options granted is charged as an expense or capitalized depending on the nature of the grant, in the period the options are vested, based on the estimated fair value at the date of grant using the Black-Scholes Option Pricing Model.   Consideration paid by the option holders to the Company upon exercise of options is credited to common share capital.



(m)

Loss per share amounts



Loss per share amounts are computed using the weighted-average number of common shares outstanding during the year. Diluted loss per share is calculated based on the treasury stock method, which assumes that any proceeds obtained on the exercise of options and warrants would be used to purchase common shares at the average trading price for the period.



(n)

Foreign currency translation

Foreign currency denominated assets and liabilities are translated at the exchange rate prevailing at the balance sheet date for monetary items. Non-monetary assets and liabilities are translated at the rates prevailing at the transaction date.  Revenues and expenses are converted at average exchange rates for the period.  Any exchange gain or loss that arises on translation is included in the consolidated statement of loss for the period.



3.

Cash and cash equivalents



At December 31, 2006, cash equivalents included $683,962 (2005 - $31,911,272) invested in guaranteed investment certificates earning interest at rates of 2.9% (2005 - 2.15% to 2.55%).



4.

Inventory



During the year ended December 31, 2006, the Company began production of limestone, which is crushed for use in various marketable products.  The inventory consists of crushed limestone stockpiles, unprocessed limestone stockpiles and blasted but unexcavated material. Inventory includes direct production costs such as fuel, labour, contractors, production overhead and direct rock excavation work.  Inventory is recorded at the lower of cost or net realizable value.  The cost of finished products and in process inventories is determined on an average cost basis.  At December 31, 2006, the Company has recorded inventory for work in progress of $3,063,613 (2005  nil) and for finished product of $2,639,584 (2005  nil).



5.

Prepaids and deposits



Prepaids and deposits consist of $5.6 million of costs management expects to recover within the next twelve months. Due to the short-term nature of this asset, it has been classified as a current asset.  The Company also has a $2 million refundable deposit on the Cedarapids crushing equipment (Note 13) which was refunded subsequent to December 31, 2006.

6.

Restricted cash



The Company pledged as collateral $3,250,000 against a demand operating line and a revolving lease line of credit, through assignment of one-year term deposits to the Royal Bank of Canada.  The Company has drawn on the operating line for a stand-by letter of credit, which is explained in Note
10 and has drawn on the revolving lease line, which is explained in Note 13.



The Company pledged as collateral $1,000,000 against future debt repayments of a crushing spread, through assignment of a guaranteed investment certificate to the Canadian Western Bank.



7.

Long-term prepaid



The Company made a payment for the estimated timber damage charges for the clearing of the currently approved limestone quarry.  The trees will be cleared as the limestone is accessed over a number of years of planned production.   This long-term prepaid will be reduced as the clearing occurs on a basis of hectares cleared over the total amount of hectares for which the timber damage payment was based, being the total approved area.

10.

Operating line of credit



The Company has a revolving credit facility with a Canadian chartered bank that provides two types of credit.  The first is a revolving demand loan, by way of either, Royal Bank prime based loans, letters of credit or letters of guarantee in the amount of $2,000,000.  The second provides for a revolving lease line of credit by way of approved lease agreements to acquire capital assets in the amount of $1,455,663.  The Company provided a general security agreement over all assets as collateral for this credit facility.  A $2,000,000 (2005  $670,000) letter of credit was drawn against the revolving demand facility as guarantee to the Alberta Government for future site reclamation obligations as outlined in Note 14 and $1,154,806 (2005  nil) was drawn against the lease line as outlined in Note 13.

Deferred revenue



In September 2003, the Company signed an agreement to sell limestone to Syncrude Canada Ltd. within Syncrude's Aurora mine, which would be extracted by Syncrude and reported monthly.  The Company received a non-refundable $100,000 payment and a payment of $50,306 to be applied against future extraction.  During the current year, no limestone was extracted (2005  nil; 2004 - nil)



12.

Other current liabilities



The Company raised capital through the issuance of flow through shares in 2003 and 2004, which provided for an indemnity to the subscriber for additional taxes payable if Birch was unable to or failed to renounce the qualifying expenditures as agreed, without limiting the recourse of the subscriber.  The Company applied for and filed the necessary forms to qualify for and renounce expenditures in 2002, 2003 and 2004 and has subsequently determined some of these expenditures do not qualify for flow through tax treatment.  The Company is exposed to costs for the indemnification of the subscribers and any assessed corporate taxes, penalties and interest.  The Company has estimated and accrued a potential liability in the amount of $2,437,781 (2005 - $3,346,264).  Subsequent to December 31, 2005, the Company amended its tax filings and the related reported tax balances have been revised to reflect this change.  Based on information available at the time of these amended filings, the Company increased its original estimate of the potential liability by $300,000.  This change has been accounted for as a change in estimate due to better information becoming available.  The offsetting entry is recorded to share capital as the amount is attributable to flow through share capital issued in prior years. This amount is subject to measurement uncertainty due to the tax filing positions of the subscribers, their tax rates and the amount of corporate taxes, penalties or interest that may be payable, which will not be known until any potentially affected subscribers as reassessed for their tax positions by the Canada Revenue Agency and these amounts become known to the Company.  To date, the Company has refunded $32,732 (2005  nil) to affected subscribers who were reassessed by the Canada Revenue Agency.  The Company believes this estimate could vary higher or lower by up to fifteen percent.

(b)         As part of the Company's operating line of credit, outlined in Note 9, the Company financed a piece of quarry equipment costing $1,235,000 at an annualized interest rate of 6.6% with a five year repayment term. The equipment has a residual value of $200,000, which is the purchase option at the end of the lease.  The Company is treating the arrangement as a capital lease. The principal and interest payments are $21,282 per month commencing on August 3, 2006.  Interest expense relating to the capital lease for the year was $26,218.



Future minimum annual lease payments under the capital lease obligation over the next five years are as follows:

Asset retirement obligation



The Company has estimated the total discounted future cost of reclaiming the site of its limestone quarry to be $1,100,000 (2005 - $360,000).  The total future undiscounted costs are estimated at $2,849,650 (2005 - $1,100,000). This amount is based on estimates provided by consulting engineers to the Company for costs that would be incurred by third parties to return the quarry to its reclaimed status as defined under the Company's environmental and operating permits.  Costs are allocated to two categories and the future site reclamation timing is determined by management for each category.  Site infrastructure will service the quarry for its estimated fifty five year life and the initial production quarry area is estimated not to be reclaimed for ten years.  The discounted future cost estimates have been determined by management using a 3% inflation rate and a 7.5% credit adjusted risk free rate.  The amounts are subject to measurement uncertainty with respect to costs in the local market for third parties to perform this work, the actual timing of reclamation, the inflation rate used and the discount rate used.  A $2,000,000 (2005 - $670,000) irrevocable standby letter of credit was drawn on the Company's operating line of credit as a guarantee to Alberta Environment for the estimated future reclamation.

| | Carrying value         | 28,537,087  | -   



The Company issued convertible unsecured subordinated debentures having a face value of $34.5 million during the year.  The debentures were issued pursuant to a public offering and mature on December 31, 2011.  The debentures are convertible into common shares of the Company at any time prior to maturity at the option of the debenture holder at a conversion price of $3.30 per share.  In the year ended December 31, 2006 no debentures were converted into shares.



The debentures are unsecured and bear interest at 6% and interest is payable semi-annually commencing on June 30, 2007.  Interest expense relating to the debentures for the year was $141,781 (2005  nil) and has been included in accrued liabilities.



The Company has classified the debentures in the financial statements according to the separate debt and equity component parts using the effective interest rate method resulting in (i) $4,775,000 being allocated to contributed surplus representing the relative fair value of the conversion feature as determined by the effective interest method, and (ii) $29,725,000 being allocated to the carrying value of the convertible debentures.



In connection with the debenture issue, the Company paid professional fees in the sum of $1,468,025.  These fees have been allocated to debt and equity on the same pro-rata basis used to allocate the original proceeds.  The debentures are shown net of the issue costs of $1,264,842 and the resulting carrying value of the convertible debentures of $28,460,158 will be accreted to the $34,500,000 principal amount over the term to maturity using the effective interest method with the corresponding interest expense being included in the consolidated statements of loss.  The accretion of the discount on the convertible debentures for the year amounted to $76,930 and is included in interest and bank charges.

The Company has a stock option plan that was established in 1994 and has been subsequently amended by the shareholders, including most recently in 2006.   The purpose of the plan is to offer persons who provide services to the Company, whether directors, officers, consultants or employees, an opportunity to obtain an interest in the Company through the purchase of common shares and to aid in attracting, retaining and encouraging the continued involvement of such persons.   The plan contains provisions stating that the option period may not exceed five years and the aggregate number of shares issuable upon the exercise of all options granted under the Plan shall not exceed 10% of the issued and outstanding common shares of the Corporation from time to time.  The options currently vest over a period of eighteen moths.  The plan is administered by the Compensation Committee of the Board of Directors who determines to whom options shall be granted including the terms and vesting of the grants.  When options are granted, the Compensation Committee sets the strike price equal to the closing price on the Toronto Stock Exchange for the previous day.

The Company has outstanding options on common shares as follows:

Loss per share amounts



Basic loss per share is calculated using the weighted-average number of shares outstanding for the year.  For purposes of the calculations, the weighted-average number of shares outstanding was 81,002,073 (2005  71,644,531; 2004  56,596,951).  All of the outstanding options have been excluded from the calculation of diluted loss per share for all periods presented as the effect common shares issuable upon exercise of share options is anti-dilutive.   All of the Company's outstanding options are available for dilution in future periods.

18.   Loss per share (continued)



The Company issued convertible unsecured subordinated debentures having a face value of $34.5 million during the year. The debentures are convertible into common shares of the Company at any time prior to maturity at the option of the debenture holder at a conversion price of $3.30 per share resulting in a potential for an additional 10,454,545 shares being issued.  All of the outstanding debentures have been excluded from the calculation of diluted loss per share for all periods as the effect common shares issuable upon conversion is anti-dilutive.



19.

Deficit



Pursuant to Section 38 of the Business Corporations Act of Alberta, the shareholders approved a reduction in the stated capital by the amount of the accumulated deficit as of June 30, 2004.  As a result, the deficit and share capital were reduced by $27,748,932.



20.

Concentration of credit risk

Assets that potentially subject the Company to concentration of credit risk are sales and accounts receivable. The Company provides credit to most of its customers in the ordinary course of business, and generally collateral or other security is not required.  The Company conducts ongoing credit evaluations of its customers and maintains allowances for potential credit losses. During 2006, the Company had two major customers that accounted for 87% of our revenues and accounts receivable. The loss of any one of our large customers could have a material adverse effect on our financial position, results of operations and cash flows, however, these particular customers are large, well-known and respected entities in their industry and management does not consider the risk unmanageable.



21.

Other limestone sale

The Company earned income from the
sale of limestone held under exploration permits outside of the active quarry.
The Company's only direct cost of sale for this income is government royalties,
which are netted against the gross sales.

(i) During 2005, 350,000 stock options at a weighted average price of $2.41 were forfeited by a director.



(ii) Expenses included in professional fees in the period were valued based on the market price of the stock at the time of the transaction.



The Company uses the Black-Scholes option-pricing model to estimate the fair-value for stock-based compensation for employees, directors, officers and advisors.  The vesting period of the options is eighteen months and their fair value was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Prior to January 1, 2003, the Company was not required to recognize compensation expense for options granted to employees, directors, officers and advisors.  Had the fair-value method been used from January 1, 2001 to January 1, 2003, the Company's net loss and net loss per share, adjusted for the amortization of stock options issued in prior periods into stock based expenses, would have been as follows:

26.  Segmented information



The Company's principal business segment, Industrial Minerals, is the acquisition, exploration, development and operation of its mineral leases and permits.  The Company also engages in ongoing exploration and research of mineral technology.  In identifying these segments the Company considers the organizational structural and areas of budget responsibility as well as the general corporate philosophy.  The Industrial Minerals division generates its revenue from the sale of limestone products such as aggregates and reagent products.  The Mineral Exploration and Technology division could generate income from the sale of technology patents or significant valuable mineral or metals discoveries.  The accounting for revenue, expense and assets attributed to each segment is based on each transaction, which is coded to separate general ledger department codes for each segment.  The Company's activities are focused in Western Canada and the Company's assets are located in Alberta.

Financial instruments



Fair values

The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities and other current liabilities approximates their fair value because of the short-term maturities of these items.



Foreign currency risk

The Company maintains cash balances and occasionally enters into transactions to purchase goods and services denominated in United States currency for which the related expenses and accounts payable balances are subject to exchange rate fluctuations.  The transactions and balances have been stated in Canadian dollars in accordance with the Company's foreign currency translation policy.

Material differences between Canadian and United States generally accepted accounting principles



The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principals in Canada (Canadian GAAP), which in most respects conform to accounting principles generally accepted in the United States (U.S. GAAP).



If these consolidated financial statements were prepared in accordance with U.S. GAAP, the impact would be as follows:

Significant differences between Canadian GAAP and U.S. GAAP that would have an effect on these consolidated financial statements are as follows:



a)

Mineral properties are accounted for in accordance with Canadian GAAP as discussed in Note 2.  For U.S. GAAP purposes, exploration costs relating to unproven mineral leases and permits as well as acquisition costs for leases and permits that do not provide for unrestricted exploration, are expensed as incurred.



The Company tracks expenditures on its mineral properties as exploration or development and under U.S. GAAP capitalizes costs relating to the development of proven reserves as defined by SEC Industry Guide 7.

|For the years ended December 31, 2006, 2005 and 2004



27.  Material differences between Canadian and United States generally accepted accounting principles (continued)



Capitalized costs are then assessed to determine if a writedown in the carrying value is necessary and any writedown would be considered an operating expense and included in the determination of operating loss for the period in which the writedown occurred.



Under Canadian GAAP, the Company was regarded as a production stage enterprise for 2005 and under U.S. GAAP the Company was regarded as an exploration stage enterprise.  On May 24, 2006, the Company filed all of the necessary applications to prove it had the legal rights to exploit its mineral leases, sales to various end-users at market prices and with expectation of regulatory approval, the Hammerstone mineral reserves met SEC Industry Guide 7 requirements for qualification as a reserve.  Subsequent to May 24, 2006, the Company is regarded as a production stage enterprise under Canadian and U.S. GAAP.
Total sales volumes for 2006 were
1,539,292 tonnes of limestone including the off-quarry sale and the Company
produced 2,244,987 tonnes of limestone during 2006.



For 2004, 2005 and to May 24, 2006, the Company's reserves did not meet the criteria for proven reserves under SEC Industry Guide 7, therefore, all expenditures on mineral properties capitalized under Canadian GAAP were expensed as operating costs under U.S. GAAP, increasing the losses and loss for each year.



b)

Under Canadian GAAP, stripping costs related to the betterment of the mineral property are capitalized while those related to removing overburden to access limestone for processing are included in the cost of inventory and cost of goods sold.



Under U.S. GAAP,
stripping costs incurred during the production phase of a mine should be
included in inventory and cost of goods sold for that period.



Management has determined that
stripping costs up to May 24, 2006 under both Canadian and U.S. GAAP would be
capitalized.





c)

Under Canadian GAAP, the conversion option embedded in the convertible debentures was presented separately as a component of shareholders' equity.  Under U.S. GAAP, the embedded conversion option was not subject to bifurcation and was thus presented as a liability along with the balance of the convertible debentures.  The principal accretion occurring under Canadian GAAP was not required under U.S. GAAP and the adjustment was included in the interest expense adjustment in the reconciliation.



Under Canadian GAAP, the accretion expense for 2006 was $76,930 and under U.S. GAAP the accretion expense was $19,441, a difference of $57,489.



d)

Commencing January 1, 2003, the Company adopted the fair value method of accounting for stock options for both Canadian and U.S. GAAP purposes. The effect of this change was that stock-based compensation is recorded as an expense instead of disclosing the effect of granting options as pro-forma information in the notes to the financial statements.



In December 2004, the FASB enacted FAS 123
 revised 2004 (''FAS 123R''), ''Share-Based Payment'', which replaces
FAS 123 and supersedes APB Opinion No. 25 (''APB 25''), ''Accounting for
Stock Issued to Employees''. FAS 123R requires the measurement of all
employee share-based payments to employees, including grants of employee stock
options, using a fair-value-based method and the recording of such expense in
the consolidated statements of loss. There was no significant impact on the
Company based on the adoption of the new requirements under FAS 123R.

Had the Company adopted the fair value method for its U.S. GAAP disclosure prior to Jan 1, 2003, the following net losses would have been reported:

New Accounting Pronouncements in U.S. GAAP



Accounting for Uncertainty in Income Taxes



In June 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48), an interpretation of FASB Statement No. 109, Accounting for Income Taxes.  FIN 48 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.  The Interpretation requires that the Corporation recognize in the financial statements, the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position.  FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure.  The provisions of FIN 48 are effective beginning January 1, 2007 with the cumulative effect of the change in accounting principle recorded as an adjustment to the opening balance of deficit.  The Corporation is currently evaluating the impact FIN 48 will have on its consolidated financial statements.



Fair Value Measurements



In September 2006, the FASB issued FAS No. 157, Fair Value Measurements (FAS 157), which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, and is applicable beginning in the first quarter of 2008. The Company is currently evaluating the impact that Fas 157 will have on its consolidated financial statements.



The Fair Value Option for Financial Assets and Financial Liabilities



In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities  Including an amendment of FASB Statement No. 115, (FAS 159) which permits entities to choose to measure many financial instruments and certain other items at fair value at specified election dates. A business entity is required to report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. This statement is expected to expand the use of fair value measurement. FAS 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, and is applicable beginning in the first quarter of 2008. The Company is currently evaluating the impact that FAS 159 will have on its consolidated financial statements.

Subsequent events



Subsequent to year-end, an additional 725,000 stock options were issued to employees, directors, consultants and officers.



On March
30, 2007 the Company completed a $15,500,000 senior secured credit facility with Brookfield Bridge Lending Fund Inc. to provide financing for the continued development and construction of the South Haul Road, recently acquired mineral permits and for general corporate purposes. The facility has a term of twelve months with an extension option for an additional twelve months. The facility may be repaid at any time without penalty.



On March 16, 2007, the Company completed a lease buyout with the Royal Bank of Canada for the lease on the quarry equipment costing $1,235,000 as described in Note
8.  The Company's lease line of credit was closed and the RBC released a restriction on a GIC for $1,250,000.
