Late 1800's-1926 - The area was prospected for talc and actinolite. An exploration pit 1.5 m square and 0.6 m deep was dug on Concession III, Lot 11 (Wilson 1926). 1930's - Diamond drilling was carried out on Concession IV, Lot 8. As well, several pits, are located on this lot. The main pit is a 3 m by 2.5 m face in the side of a hill. A second pit has a diameter of 4.6 m and a depth of 3 m (Hewitt 1972). 1940's - A trench 20 m long, 2.5 m wide and 1.2 m deep was put down on Concession III, Lot 9 (Hewitt 1972). 1982 - Steep Rock Iron Mines Limited and Canada Talc Industries Limited mapped, sampled and drilled the area. Limited bench-scale testing was carried out (Verschuren 1982).
Dec 07, 2005 (C Salo) - The area is underlain by mafic metavolcanics to the west and the Elzevir batholith to the east. Detailed mapping of the area by Verschuren (1982) shows two northwest trending zones of talc-serpentine-carbonate schist, approximately 100 to 200 m wide, occurring between the metavolcanics and the batholith (see Figure 41). Separating the two zones is actinolite schist, which is thought to represent the unaltered equivalent of the talc-serpentine-carbonate schist. The zones are composed of talc, serpentine, dolomite and magnetite in varying proportions. (Verschuren 1982).

Dec 07, 2005 (C Salo) - Wilson (1926) notes a lenticular body of soapstone on Concession III, Lot 10, 48 m by 36 m in size. The rock had a pitted appearance on weathered surface. On Concession III, Lot 11, Wilson (1926) describes a zone of 'irregularly foliated talcose dolomite' approximately 45 m in length with a width of 4.5 to 6 m. Hewitt (1972) describes the material in Concession IV, Lot 8 as veins of talc in serpentinized green metavolcanics. Dump material from one pit includes blocks of 'mauve-grey foliated talc'.
