Work History
Staked as Urn cl 1-124 (YA19142) in Jul/77 by Cyprus Anvil Mining Corporation, which carried out geological mapping and sampling in 1977 and 1978, and staked Urn cl 150 and 151 (YA51584) in Sep/80. Control of Cyprus Anvil was sold to Hudson's Bay Oil and Gas Ltd and subsequently to Dome Petroleum Ltd in 1981. Dome carried out prospecting of several of the barite showings in 1981. The property was sold to Curragh Resources Ltd in 1985.
Restaked as Bar cl 1-4 (YC09286) in Feb/99 by R. Hamel, who added Bar cl 5-8 (YC14612) in Apr/99 and carried out access trail cutting, prospecting and sampling in Nov/99.
Capsule Geology
Ten barite showings, representing two or three horizons from 5 to 12 m thick, occur over a strike length of 3.7 km in phyllitic chert of the Mississippian Mount Aho formation. A sample across the best showing (Urn 9), which is partly exposed over an area of 60 by 25 m, returned 79.2% BaSO4 across 21.5 m. Specific gravity of 3.94 and silica (the main impurity) resulted in a product that was determined to be below shipping grade at that time.
Resampling of the (Urn 9) showing was undertaken in 1999. Specific gravity determinations were done on three composite samples derived from a 150 kg sample and returned specific gravities ranging from 4.05 to 4.359. Geochemical analysis carried out on 2 of the composite samples confirmed that sulfide and calcium content was within allowable limits to meet drill mud specifications.
