- Mineralization is described as being epigenetic hydrothermal vein-type, consisting of chalcopyrite, bornite, and malachite, with gangue of pyrite, quartz, carbonate, graphite, and ankerite. Copper mineralization occurs in quartz-carbonate veins.
- The northeast-trending and steeply dipping fracture system and mineralized veining at Magnum Creek was explored for a length of 1,375 meters, 90 meters wide, and to a depth of 365 meters. Veins range from less than 1 meter up to 7.6 meters, and ten veins have been identified.
- From 1970-1974, the Churchill mine processed 598,000 tons of copper ore grading 3.0% copper.
