Work History
The occurrence was discovered in 1944 by E.D. Kindle of the GSC, who located three gold bearing quartz veins in and near the Mount Sheldon granitic intrusive. In 1990, a GSC released regional stream sediment and water geochemical open file reported anomalous values for a stream sediment sample collected from a creek draining the west slope of Mount Sheldon.
In Dec/91 Crysi Exploration Ltd. staked the Sheldon cl 1-48 (YB36641) to explore for a Fort Knox, Alaska, type mineralization. The next year the claims were optioned by Kokanee Explorations Ltd, which prospected, mapped and sampled the property. In 1993 Kokanee Explorations changed its name to Consolidated Ramrod Gold Corporation and conducted a program of lithogeochemical sampling. In 1994 Consolidated Ramrod continued geological mapping and prospecting on the property.
Capsule Geology
Gold occurs with arsenopyrite in quartz veins exposed on the flanks of Mt Sheldon. The showings occur near the contact between clastic rocks of the Ordovician-Silurian Road River Formation and a small stock of Cretaceous biotite granite.
Three veins were sampled by the Geological Survey of Canada. On the east side of the mountain, a 60 cm wide quartz vein cutting porphyritic granite is exposed for 15 m. A chip sample containing 5% arsenopyrite assayed 0.51 g/t Au. On the northeast side of the mountain, a chip sample from a 30 by 60 cm area of pyrrhotite in hornfels and limestone assayed 0.2% Cu and trace Au. On the south side of the mountain, a small quartz-arsenopyrite vein in granite assayed 0.69 g/t Au and 0.06% Sn.
In 1993, Kokanee Explorations assayed a specimen of quartz-veined megacrystic granite from the east flank of the mountain and obtained 230 ppb Au, 1.4 ppm Ag, 186 ppm As, 6 ppm Bi, 32 ppm W and 0.55 ppm Te. Work carried out by the company in 1994 showed that the best results were obtained from the granitic intrusions. Nine rock samples collected from hornfels adjacent to the granitic intrusive returned background or below detection limits for most elements including gold.
A total of 176 rock samples, 54 soil samples and 2 silt samples were collected by Consolidated Ramrod Gold. Eleven of the rock samples, all collected from granite returned values between 272 and 6 167 ppb Au. The samples are mostly megacryst, variably altered, weakly mineralized with arsenopyrite, pyrite, pyrrhotite and chalcopyrite and occasionally cut by quartz vein stockworks.
