Mining
Underground mining is supported by a main shaft and a decline, producing about 330 Kt of ore per year. The primary mining method is shrinkage stoping, with resuing used for narrower, high-grade veins. Since the commissioning of the paste backfill plant in 2021, the safer and more efficient overhand cut-and-fill method has been increasingly used.

Processing
Ore is processed at a sulphide flotation plant with a design capacity of up to 1,600 tpd, producing silver-lead and zinc concentrates sold to local smelters on market terms. A gravity circuit on the pyrite flotation tails also recovers tin concentrates.
An XRT intelligent ore sorting system was commissioned in March 2023.
A portion of the dewatered tailings is sent to the backfill system, where it is made into paste and pumped underground to reduce the surface footprint. The remaining tailings are further dewatered and dry-stacked in a facility that is progressively reclaimed—a safe and environmentally preferred method of tailings storage.

Geology
The GC deposit hosts poly-metallic veins typical of mesothermal systems. The veins are fault-controlled and occur within altered zones that can extend meters above and below the faults. They are steeply dipping, with an average thickness of ~0.8 m, and have sharp contacts with the host rock.
Silver, zinc, and lead mineralization generally follow the fault direction. High-grade zones occur at intersections of northwest–west and east–west faults, forming east-plunging shoots. To date, 256 veins have been identified at GC.
