ISR is a low cost environmentally sound process of extracting minerals

Very low comparable capital and operating costs

Used extensively for decades around the world for recovering metals and salts

30% of world wide and 90% of current U.S. U3O8 production utilizes ISR technology

Currently 26 known U3O8 and Copper ISR projects in operation or under development globally

In-Situ Recovery – Well Understood, Proven Technology

Florence Project In-Situ Recovery Process

12

Injection and recovery wells are drilled deep into the bedrock where the oxide copper mineralization is

Wells are concrete encased and sealed to protect water quality

Low pH solution, similar in strength to household vinegar or lemon juice, is pumped under low pressure through the injection wells to gently dissolve the copper

Copper rich solution is pumped to surface through recovery wells for processing into pure copper cathode sheets

Perimeter and observation wells are monitored continuously to ensure hydraulic control of fluids is maintained at all times and water quality is protected

Recent Drill Core Intersections – Florence Deposit

13

The high frequency of prolific fracture patterns and densities observed during the most recent drilling program further confirm that the Florence copper oxide deposit represents the ideal conditions for in-situ recovery of copper

The porous nature of the deposit creates significant hydraulic communication across geologic structures and rock types throughout the oxide deposit

Average copper grade in recent three drill holes was 0.47% CuT; this compares favorably with calculated model grades of 0.43% CuT (see August 16, 2011 Curis Press Release)

BHP Production Test Results (1998)

17

BHP Copper undertook an ISCR production test at Florence in 1998. Results from the test included the following:

Extensively fractured bedrock, confirmed that chrysocolla mineralization and saturated nature of deposit make it ideal for ISCR extraction

Confirmed ability to maintain full “hydraulic control” of solutions in ground

Confirmed environmental safety of full life cycle of operations including closure

Demonstrated ability to protect water quality during and after operations (14 years of subsequent water quality monitoring confirm process is safe)

Cautionary and Forward Looking Statements

30

CAUTION REGARDING FORWARD-LOOKING INFORMATION This presentation includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address exploration drilling, test results, exploitation activities and events or developments that the Company expects to occur, are forward-looking statements. Although the Company believes that the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the Company’s actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking statements. These include but are not limited to uncertainties and costs related to the Company’s exploration and development activities, such as those associated with continuity of mineralization, or determining whether mineral resources or reserves exist on a property; uncertainties related to the accuracy of our estimates of mineral reserves, mineral resources; expected production rates, the timing of expected production, the geotechnical or hydrological nature of mineral deposits, and diminishing quantities or grades of mineral resources; uncertainties related to the ability to obtain necessary environmental, land use, and other licenses, permits, approvals, surface rights and title for development projects; uncertainties and delays related to judicial or regulatory proceedings; changes in, and the effects of, laws, regulations and government policies affecting our exploration, development and mining operations, particularly laws, regulations and policies in jurisdictions in which our projects are located, relating to environmental protection and associated compliance costs, land use, effective future tax rates, the protection of the health and safety of mine workers, and mineral rights ownership; changes in general economic, market or business conditions, the financial markets and in the demand and market price for copper, gold, and other minerals and commodities, such as diesel fuel, steel, concrete, electricity and other forms of energy, mining equipment, and fluctuations in exchange rates, particularly with respect to the value of the U.S. dollar and Canadian dollar, and the continued availability of capital and financing on terms acceptable to the Company; the ability of the Company to achieve fulfillment of all conditions for drawdown under its loan agreement with RK Mine Finance Trust I; the risk of inadequate insurance or inability to obtain insurance to cover all risks associated with the exploration, development or mining of the Company’s projects; the risk of loss of key employees; changes in accounting policies and methods we use to report our financial condition, including uncertainties associated with critical accounting assumptions and estimates; environmental issues and liabilities associated with mining including processing ore; and labour strikes, work stoppages, or other interruptions to, or difficulties in, the employment of labour in markets in which we operate mineral projects or mines, or environmental hazards, industrial accidents or other events or occurrences, including third party interference that interrupt the production of minerals in our mines. Investors are cautioned that any such statements are not guarantees of future performance and actual results or developments may differ materially from those projected in the forward-looking statements. For more information on the Company, a more detailed description of the assumptions used to develop the forward-looking statements and the risk factors that may cause actual results to differ materially from forward-looking statements, investors should review the Company's continuous disclosure filings, copies of which are available at www.sedar.com.

CAUTIONARY NOTE TO U.S. INVESTORS CONCERNING RESERVE ESTIMATES The mineral reserves disclosed in this presentation have been estimated in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), as required by Canadian securities regulatory authorities. The Company is not subject to the reporting requirements of section 13(a) of section 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”). However, the Company’s U.S. investors are cautioned that SEC Industry Guide 7 under the Exchange Act, as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates contained in this news release may not qualify as “reserves” under SEC standards. In addition, disclosure of “contained ounces” is permitted disclosure under Canadian regulations; however, the SEC only permits Exchange Act reporting companies to report reserves in ounces, and requires reporting of mineralization that does not qualify as reserves as in place tonnage and grade without reference to unit measures.
