Met Testing of Igor Samples Show +88% Recoveries for Gold with Milling,74-76% Recoveries for Gold in Column Leaching
Vancouver, British Columbia – Peruvian Precious Metals Corp. (the “Company” or “Peruvian”) Peruvian is pleased to announce results from metallurgical testing on two bulk samples of typical oxidized gold and silver mineralization collected from the Callanquitas structure at the Igor project in northern Peru. The test work was performed by BM Ingenieros SAC of Lima, Peru (“BMI”). Metallurgical testing was designed to evaluate two different processing alternatives for gold and silver: Heap leaching and agitated leaching (milling). The results, +88% recovery for gold (77% for silver) in agitated leach and from 74 to 76% recovery for gold in column leaching, shows that mineralized rock from Callanquitas can be successfully treated in a conventional mill process plant (carbon-in-pulp, “CIP”) and that low-cost heap leaching may be a viable treatment option. The results are described in detail below.
