| - Crystals are pseudomorphed to talc. | |
| FeAsS - Occurs as subhedral to euhedral grains locked in massive quartz in outcrops near the west adit. | |
| Cu - Occurs as micro-dendrites of native copper within massive quartz. | |
| CuS - Occurs as small anhedral grains of indigo blue/black covellite in outcrops near the east adit. | |
| FeS2 - Occurs as massive and small grains. | |
| SiO2 - Occurs as terminated crystals to a few centimeters within cavities. | |
| Mg3Si4O10(OH)2 - Talc pseudomorphs after anthophyllite occur in outcrop near the east adit. The pseudomorphs are tan-colored striated prismatic crystals to about 5 cm associated with massive sulfide and schorl. | |
| - Occur as fine black sprays associated with massive sulfide in outcrops near the east adit. |
