WebMar 16, 2024 · The main ore mineral is pyrite. The mineral—to varying degrees oxidized, often large, cubic, and pentagon dodecahedral, and up to 1.0 cm across—grows on quartz druse crystals. Fine-grained pyrite, more often oxidized, forms concentrations, with massive veinlets up to 0.5 cm thick at the base of quartz druses and host beresites.
