Dec 07, 2005 (B Nelson) - Sulphide zone contained up to 40% pyrrhotite, 20% pyrite and traces of chalcopyrite as thin stringers, blebs, lenses and massive layers. Traces of chalcopyrite were reported in the drill hole. Copper values were not reported. **This occurrence does not meet the current OGS standard for a copper occurrence. It was named a mineral deposit in a previous compilation because it indicates what the compiler considered slightly anomalous base metals in the ground.**
Dec 07, 2005 (B Nelson) - Not known.
