Soil, Till, Bedrock
Soil, till and bedrock sampling, NTS 11E/2, Beaver Dam gold deposit, Nova Scotia, 1986.
(requires an Internet connection)
In 1986, a number of hand dug pits and backhoe excavations were made in the overburden across and down-ice from the Beaver Dam deposit, and a smaller zone of similar mineralization, the Mill Shaft occurrence. Samples of B-horizon soil developed on till and samples of fresh till were collected at each site where possible. Approximately 125 B-horizon and more than 30 till samples were collected. Bedrock and bedrock chips encountered during an overburden drilling program were also sampled. A summary of the work can be found in Prospecting in Areas of Glaciated Terrain – 1988.
5 size fractions obtained (<2.00 mm ground to < 75 µm; 2000-180 µm ground to <75 I,’ 180-63 µm; 63-2µm; <2 µm) and analyzed for Au, As, Sb, Cu, Zn, Co, Fe, Mn, Cr, Ba, Mo, W, Hg, Pb, Cd and Ag using AAS and ICP at Bondar-Clegg.
