| Host rock: | Comus Formation |
| Host type: | Limestone |
| Associated rock: | Osgood Mountain Stock |
| Associated type: | Diorite |
| Structure: | Northeasterly Pinson Trend (Range Front Fault System)., Rocks Are Typically Contorted Due To Pre-Ore Folding. Fault Offsets In The Alluvium Indicate Post-Ore Movement. |
| Alteration processes: | Decalcification, Silicification, Oxidation. Decalcification And Iron Oxide Staining Are Associated With Ore. Decalcification Extends Well Into Barren Wall Rocks. Jasperoidal Silicification Occurs Locally. |
