Gold and silver exploration company Minco has awarded the preliminary feasibility study for its 100% owned La Laguna silver tailings project in the Zacatecas region of Mexico to Toronto-based Micon International. Micon have now started work on the study, which is expected to last some three months.
Minco has the licence to extract 14 million tonnes of tailings from the Mexican lake and continues to evaluate the surrounding land based tailings dumps. These are estimated to be 27 million tonnes within a five mile radius of the lake.
Minco plans to produce about 3.5 million ounces of silver a year, with an annual revenue of $21m for at least seven years.
