Our newest project, Shirley Basin, is one of the assets acquired as a part of the Pathfinder Mines Corporation transaction which we closed in December 2013. We also acquired all the historic geologic and engineering data for the project, which has nearly 3,200 historic drill holes. The Preliminary Economic Assessment was issued January 27, 2015. Baseline studies necessary for permitting and licensing of the project are complete, the WDEQ application for permit to mine has been submitted, and work on other applications is underway.

Cautionary Note to U.S. Investors: The terms “mineral resource,” “measured mineral resource,” “indicated mineral resource” and “inferred mineral resource,” as used on our website are Canadian mining terms that are defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). These Canadian terms are not defined terms under United States Securities and Exchange Commission (“SEC”) Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC by U.S. registered companies. The SEC permits U.S. companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Accordingly, note that information contained on this website describing the Company’s “mineral resources” is not directly comparable to information made public by U.S. companies subject to reporting requirements under U.S. securities laws. U.S. investors are urged to consider closely the disclosure in our Form 10-K which may be secured from us
