Point Location Description: ' py ' symbol 3.5 km SE of Tincap.
Location Method: Conversion from MDI
Access Description: From the junction of Hwy 2 and 29/42 in Brockville, drive N on Hwy 29/42 for 11/4 ml and turn SW onto a concession road. Drive 11/4 ml and, just before the second bend on the road, take a road that leads S and to the pit (about 250 yds from the concession road).
Mineral location : cacoxenite, pyrite and pyrrhotite. pre- 1863-1879 : the Brockville Chemical Company operated the mine and a plant (from 1869) that produced sulphuric acid (in Brockville). The acid plant continued after the mine closed, using U.S. pyrite, until 1884. The main pit was sunk to 250 ft and a shaft, at the bottom of a 50 ft pit, was sunk about 200 ft. From this shaft levels were run to the SW (the Big Drift), S (Gardener Drift) and E. The Big Drift was over 400 ft long and, in one place, over 300 ft wide. In the Gardener Drift the ore was lost. In the E drift calcite and ore were abundant but it had to be abandoned due to water and unsafe walls (no timbering). Mining of open-cuts appears to have been carried out in a piecemeal and unsafe fashion.
Province: Grenville
Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - Pyrite occurs with calcite in a series of irregular lenses conformable with the enclosing granite gneiss. Quartzite and marble and the gneiss have been intruded by a diabase dyke. This is the only known location in Canada of cacoxenite. The pyrite, which is high in cobalt, is commonly massive but also occurs in cubes and octahedrons up to 2 inches long. Calcite is massive and crystalline. Pyrrhotite occurs as crystals which may reach several inches in length. Also : steatite, hisingerite, siderite, apatite and feldspar.
