Pinnacle Silver & Gold has signed an agreement with well-known metals trader Auramet, under the terms of which Auramet has agreed to provide US$5 million in finance for the development of the El Potrero gold and silver project in Mexico. The El Potrero project comprises several old mines that could be brought back into production pretty quickly and relatively cheaply, if shown to be economic. Pinnacle is currently mid-way through a major drilling campaign there. Chief executive Bob Archer joins Vox to tell us more.
