Huaron is a hydrothermal polymetallic deposit of silver, lead, zinc, and copper mineralization hosted within structures likely related to the intrusion of monzonite dikes, principally located within the Huaron anticline. Mineralization is encountered in veins parallel to the main fault systems, in replacement bodies known as “mantos” associated with the calcareous sections of the conglomerates and other favourable stratigraphic horizons, and as dissemination in the monzonitic intrusions at vein intersections. The mineralized veins vary from a few centimetres to up to 10 metres wide, and may extend along strike for up to 1,800 metres. Most of the structures show open mineralization at depth and along strike and have excellent exploration potential. Vein orientations vary but generally trend east-west or north-south.

Mining is undertaken using a combination of conventional cut and fill, mechanised cut and fill, and mechanized sub-level long hole stoping methods. The selection of the mining method depends on the location, width, orientation, and ground conditions of the vein to be mined, as well as the ground conditions of the footwall and hangingwall. Drift and fill mining is planned to be implemented to safely mine areas where ground conditions are expected to be significantly less competent than those typically encountered.

Huaron operates an 870,000 tonne per year capacity mill using froth induced flotation technology to produce silver in copper, lead, and zinc concentrates. The mill flowsheet consists of three-stage crushing, ball mill grinding, and selective flotation of the ore to concentrates, followed by thickening and filtering of the concentrates.
