The original rock contained pyrite (FeS2) which oxidized (rusted) with the sulfur carried away with rain water while the iron (Fe) remained in place staining the rock red to brown. Pyrite is often gold-bearing and if the gold occurs as free gold within the pyrite crystal structure, the pyrite will dissolve while the free gold will remain in place.
