Exploration History

Several pits have been put down. The main pit with a 10' X 8' face is blasted into the east side of a hill of sheared and serpentinized green volcanic rock. Two hundred feet north of the main pit is a second pit 15 feet in diameter and 10 feet deep excavated in the base of a mafic volcanic ridge. Dump material includes blocks of round-grey foliated talc. There are numerous other small pits with no rock showing some diamond drilling is reported to have been carried out in the 1930's. 1984: Application made May 1984 to operate a talc quarry.




Geology Comments

Dec 07, 2005 (C Salo) - The talc orebodies are hosted by dolomitic marble which is tremolitic in part. Interlayered with the marble are quartzite, amphibolite and phyllite. Dark coloured dykes called 'madocite' by Wilson (1926) cut the metasediments. A pink albitic granitic stock, the Moira Granite, outcrops approximately 800 m southeast of the mine site. The general strike of rocks in the area is northeast with a subvertical dip. Paleozoic sediments, sandstone, con glomerate and limestone overlie the Precambrian rocks in some areas of the property. The geology is described in more detail in LeBaron and van Haaften (1989).

Lithology Comments

Dec 07, 2005 (C Salo) - The Henderson orebody contains large masses of compact steatite which varies in colour from green to white (LeBaron and van Haaften 1989). Simandl and Ogden (1982) noted that near the contact between the micaceous dolomite and the talc body, the dolomite is partially steatitized. The company supplies small sculpture blocks to artists from time to time. At present the steatitized unit is not accessible underground. The unit is reported to be massive and unfractured but large blocks cannot be brought to surface. The soapstone is apple green, 60 to 70 percent talc and has a hardness of 2 to 2 1/2 on Moh's scale. (Dirk Demont, Canada Talc Ltd., personal communication 1990).
