1872: J.C. Haskins discovered the veins and sunk a series of test pits on them. 1885: A.S. Hall acquired the property and sank a shaft to 6.1 m. 1886: Hall sold portions of his holdings to C. Gehl, A.H. Macdougall, and W.R. Bell. A few shallow test pits and three small open cuts were cut on the veins.

Feb 07, 2018 (Therese Pettigrew) - In the northeast part of mining location R 70 two nearly parallel veins have been developed. They strike approximately east and are about 10 chains apart. On the southern vein two test pits, 100 feet apart, have been sunk to depths of 4 and 7 feet, respectively. On the northern vein an open-cut has been driven 20 feet into the west side of Silver Hill and at the portal a shaft has been sunk at least 25 feet. Two smaller open-cuts have been made one above and one below that previously mentioned; the three open-cuts are within a horizontal distance of 50 feet. The southern vein is 2 feet wide and occurs in a fracture in diabase. The northern vein where exposed is in a fault shatter zone 4 feet wide traversing flat-lying Animikie iron formation; the eastern extension of the vein presumably passes •through a diabase sill capping Silver Hill. The strike of the southern vein varies from south 75 degrees east to south 65 degrees east, the dip is 80 degrees south. The northern vein strikes north 77 degrees east and dips 75 degrees south. The southern vein consists of coarsely crystalline white calcite and associated green fluorite, barite, colourless, and rarely amethystine, quartz, and pyrite. In the case of the north vein, vein material makes up approximately one-third of the substance within the shatter zone. It shows the same mineral assemblage as the southern vein, with the exception that no barite is visible. Mr. Ingall reports that a little silver and argentite were found in this vein (Tanton, 1931). A sample was taken by Ingall in his 1886 visit to the property. The sample contained calcite, quartz, fluorite, specks of pyrite, and was coated in parts with hydrated iron peroxide. The sample assayed traces of gold and 0.525 opt Ag (Ingall, 1888).
