Further Potassium-Argon Age Dating at Copper Mountain, B.C..
V. A. G. PRETO ; W. H. WHITE and J. E. HARAKAL,
Potassium-argon age dating performed recently on intrusive rocks from Copper Mountain indicates that the satellite Smelter Lakes and Voigt stocks have radiometric ages which are indistinguishable from that of the Copper Mountain stock, as determined by Sinclair and White (1967). The complex of intrusive rocks known as the Lost Horse Intrusions also yields essentially t he same radiometric age, as do biotite-sul phide-pegmatite veins on Copper Mountain.
