The property was first developed by Cochrane Cobalt Mining Co. Ltd from 1907 to 1916, and then several other companies after that with closure in 1962. The deposit was developed by two shafts with the deepest being an inclined shaft (70 degrees) to a depth of 630 ft. Total production was approx. 33,000 oz.Ag and 3,000 lbs. Cobalt.

| ⓘ Native Silver Formula: Ag |
| ⓘ Pyrite Formula: FeS2 |
| ⓘ Sphalerite Formula: ZnS |
| ⓘ Sternbergite Formula: AgFe2S3 Colour: pinchbeck brown Description: Along with the 14 inch vein of Stromeyerite Reported in the Ottawa Citizen on Aug 31, 1907, There were also reports of probably Sternbergite as a new mineral being an "amalgam of the sulfides of Silver and Iron" called "gyropyrite" That was reported in the Mining and Scientific Press on Sept 14, 1907 On page 12 of the Ottawa Citizen for Sept 3, 1907. They say the sulfide of Silver and Iron is argentopyrite! Sternbergite and argentopyrite were not sorted out until Quellmalz sorted them out from their pseudomorph Frieseite in 1970. So since specimens are unavailable and Sternbergite more common, it is probable that sternbergite occured but it is possible that Argentopyrite was there as well.
