About Capstone Mining Corp.

Capstone Mining Corp. is a Canadian base metals mining company, committed to the responsible development of our assets and the environments in which we operate. We are focused on copper, with three producing mines; the Pinto Valley copper-molybdenum mine located in Arizona, US, the Cozamin copper-silver-zinc-lead mine in Zacatecas State, Mexico and the Minto copper-gold-silver mine in Yukon, Canada. In addition, Capstone has two development projects; the large scale 70% owned Santo Domingo copper-iron-gold project in Region III, Chile, in partnership with Korea Resources Corporation, and the 100% owned Kutcho copper-zinc-gold-silver project in British Columbia, Canada, as well as exploration properties in Canada, Chile and Mexico. Using our cash flow and strong balance sheet as a platform, Capstone's strategy is to continue to grow with mineral resource and reserve expansions and exploration, and through acquisitions in politically stable, mining-friendly regions. We will pace our growth with our financial capacity, ensuring we retain, as a priority, sufficient financial flexibility to meet the requirements of our existing operations and our committed development projects, while maintaining an adequate cushion to deal with market volatility and operating risks inherent in the mining industry.

Cautionary Note to United States Investors

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. Without limiting the foregoing, this news release refers to a technical report that uses the terms "indicated" and "inferred" resources. U.S. investors are cautioned that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. U.S. investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. U.S. investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization and resources contained in this news release may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
