About the Palmer Project

Palmer is a resource expansion stage, high-grade volcanogenic massive sulphide (VMS) project that hosts a 4.75 million tonne inferred resource estimate grading 1.84% copper, 4.57% zinc, 0.28 g/t gold and 29.0 g/t silver (see Note 1) and is currently being updated to evaluate the effect of several successful drill programs completed since the initial resource in 2010. The project is located in a very accessible part of coastal southeast Alaska, with road access to the edge of the property and within 60 kilometres of the year-round deep sea port of Haines. Mineralization at Palmer occurs within the same belt of rocks that is host to the Greens Creek mine, one of the world's richest VMS deposits. There are at least 25 separate base metal and/or barite occurrences and prospects on the Palmer property, indicating the potential for discovery of multiple deposits.

Note 1: See the Company's technical report entitled, "Palmer VMS Project, Southeast Alaska, Mineral Resource Estimation and Exploration Update" dated March 4, 2010 and available on www.sedar.com. Resource estimate utilizes an NSR cut-off of US$50/t with assumed metal prices of US$700/oz for gold, US$12/oz for silver, US$2.25/lb for copper, and US$0.85/lb for zinc, with estimated metal recoveries of 55%, 55%, 90%, and 90% respectively. An "Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. Due to the uncertainty that may be attached to Inferred Mineral Resources, it cannot be assumed that all or any part of an Inferred Mineral Resource will be upgraded to an Indicated or Measured Mineral Resource as a result of continued exploration. Confidence in the estimate is insufficient to allow the meaningful application of technical and economic parameters or to enable an evaluation of economic viability worthy of public disclosure.
