The Los Gatos mine operation consists of an underground mine, processing plant and associated surface facilities. The Los Gatos processing plant employs a conventional design and flotation technology typical of silver-zinc-lead operations. The processing flow sheet is comprised of a crushing and grinding circuit, including jaw crusher, semi-autogenous grinding (SAG) mill and ball mill, which feeds a flotation plant consisting of lead and zinc flotation circuits (including rougher, regrind and cleaner stages), lead and zinc concentrate thickening, and tailings thickening. The current operating throughput target is approximately up to 4,000 tonnes per operating day (tpod).
