About Capstone Mining Corp.
Capstone Mining Corp. is a Canadian base metals mining company, focused on copper. We are committed to the responsible development of our assets and the environments in which we operate. Our three producing mines are the Pinto Valley copper mine located in Arizona, US, the Cozamin copper-silver mine in Zacatecas State, Mexico and the Minto copper mine in Yukon, Canada. In addition, Capstone has two development projects; the large scale 70% owned copper-iron Santo Domingo project in Region III, Chile, in partnership with Korea Resources Corporation, and the 100% owned Kutcho copper-zinc project in British Columbia, Canada, as well as exploration properties in Chile and US. Capstone's strategy is to continue to extend the lives of our current mines with mineral resource and reserve expansions, maintain the optionality on the Santo Domingo development project, prudently progress the exploration portfolio and grow through acquisitions in politically stable, mining-friendly regions. We will pace our growth with our financial capacity, to 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. Our headquarters are in Vancouver, Canada and we are listed on the Toronto Stock Exchange (TSX). Further information is available at www.capstonemining.com.
