| FBI warns of threat from anti-government extremists WASHINGTON | Mon Feb 6, 2012 7:21pm EST (Reuters) - Anti-government extremists opposed to taxes and regulations pose a growing threat to local law enforcement officers in the United States, the FBI warned on Monday. These extremists, sometimes known as "sovereign citizens," believe they can live outside any type of government authority, FBI agents said at a news conference. The extremists may refuse to pay taxes, defy government environmental regulations and believe the United States went bankrupt by going off the gold standard. 52

| Endnotes 57 The Company has included non-GAAP performance measures, total cash costs, by-product and co-product, per gold ounce, throughout this document on a historic and estimated forward looking basis. In the mining industry, these are common performance measures but do not have any standardized meaning. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the Company and certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Total silver cash costs on a by-product basis are calculated by deducting by-product gold revenues from production cash costs. Such information relating to the San José Mine is provided to us by Minera Santa Cruz S.A. who is responsible for and has supplied to the Company all reported results from the San José Mine. The technical information pertaining to the San José Mine contained herein is, with few exceptions as noted, based entirely on information provided to the Company by Minera Santa Cruz S.A. ("MSC"). The Company's joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this information. As the Company is not the operator of the San José Mine, there can be no assurance that production information reported to the Company by MSC is accurate, the Company has not independently verified such information and readers are therefore cautioned regarding the extent to which they should rely upon such information. The Company has also made estimates of potential future cash flow from MSC based on a sustained silver price of $34/oz and gold price of $1,700/oz as well as assumptions over operating costs, capital expenditures, production levels, taxes, and other factors which are beyond our control since we are not the operator of the San José Mine. The feasibility of mining at our El Gallo Complex and Gold Bar Project, has not been established in accordance with SEC Guide 7, and we have no proven or probable reserves on those properties as defined by U.S. law. A "reserve," as defined by regulation of the SEC, is that part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. A reserve requires a feasibility study demonstrating with reasonable certainty that the deposit can be economically extracted and produced. There are no assurances that we will be able to prove that there are reserves at the El Gallo Complex and Gold Bar Project. The forward looking information contained in this presentation such as estimated timelines to production, production levels, capital expenditure requirements, and operating costs have been estimated without the benefit of a feasibility study so there can be no assurance over the accuracy of those estimates or that commercial production will be achieved.
