Work History
Staked as Homestake cl (13078) in Jun/20 by L. Walsh etc. Optioned in Jun/28 by T. McKay, who explored with 26.8 m of shafts and 38.4 m of drifting in 1928-31. R.G. Lee purchased control from L. Walsh, etc about 1950.
Optioned in Jun/51 by Lustre Yukon ML and in 1962-63 by United Keno Hill ML, which did extensive bulldozer trenching on two veins. Additional bulldozing financed by B. Kunze in 1966 uncovered a new vein and the property was optioned in 1967 by Hecla Mg C of Can L which carried out 107 m of crosscutting, 143 m of drifting and 203.9 m of underground drilling (4 holes).
The property was transferred to Evelyn Lee in Mar/71 and explored by further trenching in 1974.
Capsule Geology
Both a longitudinal and a transverse-type vein are present. United Keno exposed the longitudinal vein for more than 90 m along strike. Mineralization consists of erratic lenses of arsenopyrite and galena in a quartz carbonate gangue. Arsenopyrite sections assayed as high as 102.9 g/t Au over narrow widths.
A transverse vein was uncovered for a length of 30 m in 1966 with a width varying from 3 to 7.6 m. Mineralization consists of tetrahedrite and galena in a carbonate gangue. A chip sample across a 7.6 m width assayed 1131.4 g/t Ag, 2.2% Pb and 0.5% Zn. No mineralization was found underground, 45 m below the surface trenches.
