Summary - Turnagain Project
Preliminary Economic Assessment
Production of Nickel/Cobalt Concentrate
AMC Mining Consultants (Canada) Ltd.
The PEA, published December 2011, models production of an 18% Ni, 1% Co concentrate for sale to smelters. Initial mill throughput of 43,400 tonnes per day ramps up to 84,600 tonnes per day in year 6.
After year 21, low grade stockpiles are processed.

The PEA includes the use of inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. The study is preliminary in nature and there is no assurance the mining, metal production, or cash flow scenarios outlined in this report would ever be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

MINERAL RESOURCES
The total estimated resource for the Turnagain Project, at a 0.1% Ni cut-off, is as follows:
Measured : 227,379,000 tonnes @ 0.22% Ni and 0.014% Co
Indicated : 638,103,000 tonnes @ 0.21% Ni and 0.013% Co
Inferred : 976,295,000 tonnes @ 0.20% Ni and 0.013% Co
DEVELOPMENT PLAN
The PEA evaluates the development of the Turnagain deposit by conventional open-pit methods with trucks and shovels. Material will be processed using a conventional concentrator to produce nickel-cobalt concentrate.

OPPORTUNITIES
Potential for payable platinum and palladium in the concentrate
Improved metallurgical performance
Increased mine life with existing defined resource and Hatzl area resource
Optimization of tailings storage facility construction
Additional resource potential for both nickel/cobalt and platinum/palladium
within the Turnagain ultramafic complex
Third party ownership/operation of the transmission line
Financing of the proposed interconnection fee tariffs over five years
Shared access development cost
We advise U.S. investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize them. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories would ever be converted to reserves.
