Project Funded by the Minerals Coordinating Committee Through the Mineral Diversification Program

Abstract extracted from page 1 of Report 264:

ABSTRACT The Geodrilling Project (Project 264) is an ongoing program of siting, drilling, logging, sampling and analyzing bedrock drill holes. This report describes 12 drill holes which produced 2,057 feet of drill core from 6,562 feet of total drilling.

Eleven drill holes were located in the Archean granite-greenstone terrane, while one drill hole penetrated hornfelsed Early Proterozoic sediments at the contact with the Middle Proterozoic Duluth Complex.

A total of 232 core samples and 6 outcrop samples were analyzed for Au, Pt, Pd, Ag, As, Sb, Bi, B, Ba, Se, Te, Cu, Ni, Co, Cr, V, Ti02, Fe203, MnO, MgO, Al203, P20S, Si02, K20, Na20, CaO, Rb, Sr, S, F, Sn, W, Mo, Pb, Zn, Cd, Li, Be, Ga, Sc, Y, La, Ce, Zr, Nb, Ta.
