Exploration Access Agreement Enter For Copper Cities Project

VANCOUVER - Capstone Mining Corp. has entered into an 18-month access agreement to conduct drill and metallurgical test work at BHP Copper Inc.’s Copper Cities project located 10 km east of the Pinto Valley Mine.

Darren Pylot, CEO, said, “I am excited that we have started test work on a property neighboring our flagship Pinto Valley operation.” Mr. Pylot added, “Historic drill data from over 300 holes suggest a shallow copper target and a potentially low strip ratio pointing to a significant development opportunity.”

Copper Cities was developed in the 1950s as a part of America’s national effort to increase copper production to support the war effort in Korea. The operations included open pit mining, concentrating and leaching of copper ores. The mining and milling concluded in 1978 while leaching continued until 1982 when the site closed. Over the mine life according to USGS records, a total of 68.7 million tonnes of ore was milled at an estimated feed grade of approximately 0.66% with production of 895 million pounds of copper including 75 million pounds of copper cathode.
