Exploration History

1890-91: veins were discovered by W. Harris. A 6.1 m deep shaft was sunk, but it filled with water shortly thereafter. 1892: W. Harris and Mr. Dobie conducted development consisting of a series of test pits ranging from 3.0-7.9 m in depth. The shaft was sunk to 7.9 m. An adit was started from the foot of the hill. 1893: the north vein was exposed by 2 shafts and several test pits. The south vein showed some test pits and stripping. Some crosscuts were also found on the vein. 2018: Honey Badger Exploration carried out prospecting and sampling.

Mineralization Comments

Feb 06, 2018 (Therese Pettigrew) - The southern composite vein occupies a shatter zone 3.5 feet wide in flat-lying Animikie iron formation. It strikes north 86 degrees east and dips vertically. The vein material is concentrated in two parallel fissure fillings, the north one has a width of 14 to 22 inches, the south one is 4 inches wide; the intervening rock is cut by small branching stringers. Calcite and white quartz occur in approximately equal amounts, accompanied by some amethyst and small amounts of sphalerite and galena. The northern composite vein occupies a fracture zone 3 feet to 3.5 feet wide in Animikie iron formation. It strikes north 82 degrees east and dips vertically. The vein material is largely concentrated in a vein 1 to 2.5 feet wide; its southern wall is well defined, whereas on the north side it is adjoined by fractured rock in which there is a ramifying network of stringers. The vein material consists of white calcite, quartz, sphalerite, and galena. The sphalerite makes up approximately 2 per cent of the exposed vein material, galena makes up a much smaller proportion (Tanton, 1931). Newspaper articles (1891-93) from the Resident Geologist’s Files, Thunder Bay, report that argentite and native silver were found on the property. Minor amounts of pyrite were reported too. Sample 1099079 collected by Honey Badger Exploration in 2018 returned 0.93 g/t Ag, 0.46% Pb, and 13.69% Zn (Assessment report 20000017904).
