Work History

Staked as Sunset, Sunrise, Wheaton and Golden Slipper claims (8745) in Aug/06 by G.M. Stevens, who drove a 26 m drift and 6 m cross-cut on the Golden Slipper claim in 1909. The Sunrise, Wheaton and Golden Slipper claims were sold in 1916 to Lottie Anderson, who took them to lease in 1930 and explored with 15 m of adit between 1923-27. They were later sold to Mrs R. Rocki.
The area surrounding the Crown Grants was staked as Alta cl 1-100 (Y8085) in May/66 by Silver Pack Mining Ltd as part of its adjoining Tally Ho property; restaked as EB cl 1-16 (Y78480) in Apr/74 by E. Bernier and as Caribou cl 1-24 (YA62164) in Aug/81 by Westfort Petroleum Ltd, which performed mapping and geochemical sampling later in the year.
T. McCrory purchased the Crown Grants and added Buffalo cl 1-12 (YA75776) in Oct/83 and sold the property to Tally-Ho Exploration Ltd later in the year. Tally-Ho performed mapping, sampling and trenching in 1984 on behalf of Wheaton River Joint Venture (Tally-Ho, Euro-Petroleum Corporation and Wesclift Resources Ltd). Wesclift's interest was transferred to Permian Resources Ltd in 1985 when the joint venture explored with mapping and geochemical sampling, bulldozer trenching and 5 percussion holes (240.7 m).
Restaked as Tempus Fugit cl 1-4 and 6-16 (YB46407) in Sept/93 by Mountain Highgrade Mines Ltd and Main Street Mining Ltd to surround the Sunrise, Wheaton and Golden Slipper Crown Grants owned by Main Street. The following year the partnership carried out a program of geophysical surveys, sampling, excavator trenching, road building and underground rehabilitation on the claims and the Crown Grants.

Capsule Geology

On the Golden Slipper claim several tons of quartz float was found lying on granitic rocks near the summit of Mount Stevens. The quartz contained small amounts of disseminated galena, free gold and sylvanite and although the source was not located, it appeared not to have travelled far. A quartz vein on the Sunrise claim, to the east, is up to 2.1 m thick and 15 m long and contains some galena, pyrite and native gold. This vein was explored with three short cross-cuts and an open-cut. A galena-bearing sample taken from the Sunrise Vein by MacLean assayed only trace in Au and Ag. Three grab samples from open-cut No. 4 on the Golden Slipper claim averaged 55.2 g/t Au and 1 066.3 g/t Ag. Warren reported that hedleyrite, tellurbismuth, and hessite are present on the property.
Sampling in 1984 returned assays of 41.1 g/t Au, 1 405.7 g/t Ag and 21.9 g/t Au, 1 200.0 g/t Ag on specimens from two adit dumps on the west face of Mount Stevens. In 1985, a 50 cm chip sample across a galena bearing quartz vein (Trench 85-1) assayed 2.5g/t Au and 794.1 g/t Ag. The veins are apparently associated with narrow, northwest-trending rhyolite dikes of Eocene age that cut Triassic volcanic rocks and Cretaceous granodiorite. The 1985 drilling outlined several anomalous zones with the best 1.5 m intersection for Au (740 ppb) in Hole 2 and Ag (25 ppm) in Hole 3.
The 1994 geophysical surveys attempted to locate the mineralized quartz veins. Although the total field magnetic field survey determined that the quartz veins were associated with magnetic lows, the metamorphosed volcanic rocks and the rhyolite dikes also returned magnetic lows. The VLF-EM survey failed to detect the quartz veins. Trenching uncovered several new quartz veins on the summit of Mt Stevens. A 40 cm chip samples taken from a vuggy white quartz vein, containing limonite in its cavities (trench 94-5) assayed 1.95 g/t Au and 64.1 g/t Ag. Rock samples collected from a quartz vein located in the Stevens No. 1 Adit (Golden Slipper Crown Grant) returned up to 49.3 g/t Au and 573.9 g/t Ag.
