Work History
Mineralization was first noted in this vicinity by the GSC about 1953. Staked as DB cl (YA34420) in Jun/78 by Klinkit JV (DuPont of Can EL & Duval Corp), which performed mapping and geochem sampling later in 1978 and trenching in 1979.
Restaked as FF cl (YA67170) in Jun/81 by DC Synd (Cominco & Dome), which performed mapping and geochem sampling in 1981 and 1982, mag surveys in 1982 and 1983 and 2 holes (282 m) in 1984.
Restaked as Mul cl 1-4 (YB84643) by H. Hibbing in Jun/96.
Capsule Geology
The showing, reported by the GSC, consisted of pyrite, base-metals and a little gold and silver associated with rusty garnet-amphibole-epidote skarn. This is presumably part of a zone discovered in 1981 that consists of small pods (up to 2 m by 7 m) of pyrrhotite, chalcopyrite, arsenopyrite and sphalerite in a large skarn zone carrying low tin and tungsten values. The skarn has formed in Mississippian limestone at the margin of the Cretaceous Hake Stock and measures 700 m long and up to 11.7 m thick. Preliminary sampling gave assays in the 0.06 to 0.1% WO3 and 0.1 to 0.2% Sn ranges. Mineralization is hosted by garnet-epidote-magnetite skarn that occurs at the base of the limestone unit. It is underlain, in turn, by a siltstone, tuff and agglomerate sequence and a porphyritic volcanic flow. The entire sequence may be overturned.
The 1984 drilling tested a thick flat-lying zone and intersected widely-separated sections of magnetite containing rare chalcopyrite and abundant pyrite. The magnetite-rich intersections averaged 0.05% Sn, 1.2 g/t Ag and less than 1.08 g/t Au. Another skarn horizon at a higher stratigraphic level assayed 0.36% Sn over 1.1 m.
