Galena a lead sulfide PbS is heavy brittle and breaks into cubes. Sphalerite is a zinc sulfide ZnS mineral that is brownish yellowish or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite FeS which is also called fool’s gold is common in nearly all types of rocks.

Ore occurs as coatings on boulders within the brecciated ore body. Mineralization includes galena lead sulfide sphalerite zinc sulfide and pyrite iron sulfide . Silver occurred in the galena ore at about 68 ounces of silver per ton of galena. Between 500 000 and 1 000 000 worth of silver and lead were recovered from the Bull Domingo Mine.
