CAUTIONARY STATEMENT This presentation includes certain “forward-looking statements”. These statements are based on information currently available to the Company and the Company provides no assurance that actual results will meet management’s expectations. Forward-looking statements include estimates and statements that describe the Company’s future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by terms such as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”, or “plan”, or their conditional or future forms. Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results relating to, among other things, results of exploration, project development, reclamation and capital costs of the Company’s mineral properties, and the Company’s financial condition and prospects, could differ materially from those currently anticipated in such statements for many reasons such as: changes in general economic conditions and conditions in the financial markets; changes in demand and prices for minerals; litigation, legislative, environmental and other judicial, regulatory, political and competitive developments; technological and operational difficulties encountered in connection with the activities of the Company; and other matters discussed in this news release. This list is not exhaustive of the factors that may affect any of the Company’s forward-looking statements. These and other factors should be considered carefully and readers should not place undue reliance on the Company’s forward-looking statements. The Company does not undertake to update any forward- looking statement that may be made from time to time by the Company or on its behalf, except if required to do so by applicable securities laws.

Appendix: Zinc Outlook

“The predicted rally in prices comes as Xstrata Plc (XTA) closes its Brunswick mine in this month, an operation which yielded 2.9 million tons of ore last year. About 841,000 tons of mine output will be lost by 2014 as Xstrata also shuts the Perseverance mine in Canada and Vedanta Resources Plc (VED) closes Lisheen in Ireland.”
