VANCOUVER, British Columbia, August 8, 2013 /PRNewswire/ -- Capstone Mining Corp. ("Capstone") (TSX: CS) is pleased to announce that it has entered into an option agreement (the "Option") with Sociedad Química y Minera de Chile S.A. ('SQM") to earn up to 70% of a property, Project Providencia (the "Property"). The initial option is on 350,000 hectares (3,500 square kilometres) in Chile's II Region and would be reduced overtime to a maximum of 50,000 hectares if a joint venture is formed. The Property is located 50 kilometres east of the city of Taltal, approximately half way between Capstone's Santo Domingo Project and Anglo American's Mantos Blancos copper mine. It rests at a mean elevation of 1,800 metres above sea level, with mostly gentle topography and it benefits from the Pan-American Highway cutting through the centre of the block. Due to the unique nature of SQM's core business as a producer of specialty fertilizers and inorganic industrial chemicals, significant portions of the large Property in the Cretaceous belt have been exclusively held by SQM for decades for the value of their surface deposits of nitrates and iodine, among other minerals. The Property has seen little to no modern exploration for bedrock hosted, metallic mineral deposits, or even comprehensive geological mapping, prospecting and geophysical surveying, despite being centrally located in one of the world's largest copper mining districts. Capstone's strategy will be to cover the very large holding with several state-of-the-art airborne, remote sensing technologies to identify discrete anomalies or areas of prospectively for more detailed ground follow-up. "Capstone's strategic goal is to expand its asset base and selectively add to our portfolio of exploration projects in the Americas," said Brad Mercer, Sr. Vice President, Exploration of Capstone. "This is an excellent opportunity to look at a very large under-explored land package in the world's most prolific copper jurisdiction, with an option to make a more significant investment in stages if exploration results warrant. The proximity to Capstone's Santo Domingo Project and other copper mines offers potential synergies should exploration prove successful. " "Capstone geologists believe that the property is prospective for a variety of styles of mineralization, including iron oxide-copper-gold ("IOCG"), porphyry copper and Mantos Blancos type. Activities will be led by our Chilean geology team who were instrumental in the discovery of Santo Domingo IOCG deposit," he added.
