The mineralized zone is 20 to 25 feet wide near the fault contains 10-15% of combined galena and sphalerite. An associated rock unit is the Copper Creek Granodiorite. Ore control was faults. Alteration is silicification of the limestone.
Area structures include block faulting trending NNW. Regional trends: minor Pre-Cretaceous E- and NE-trending folds and major Post-Cretaceous NNW-trending faults.
