Geology Comments

Dec 07, 2005 (P Beach) - Sulphides in chert in greywacke.

Lithology

Lithology Comments

May 04, 2011 (A Wilson) - The shaft is inclined at about 70° north. The hanging wall of the shaft is a dark grey tuff or greywacke with fragments to 3/8". The footwall appears to be a basaltic or andesitic rock with pale creamy, green selvages. The rock in which the shaft was sunk is mainly dark greywacke with two 1-foot bands of chert, and minor siliceous laminae in the greywacke.

Mineralization

Mineralization Comments

May 04, 2011 (A Wilson) - The cherty beds contain about 10% pyrrhotite, 3% pyrite, about 1% of sphalerite and galena and a trace of chalcopyrite. Spectacular splashes of chalcopyrite, galena and sphalerite, as well as pyrite and pyrrhotite are present on a few fractures in the greywacke. Analysis of a chip sample from the two chert beds gave negative results, as follows: Au and Ag, trace only; Pb, 0.03%; Zn, 0.03%. W. Doughty reported that he obtained negative results when he burned and panned specimens for gold. The beds of chert strike 098° and dip 72° north. A grab sample of the sulphide-bearing chert, collected by P. Born in 1985 returned 120 ppb Au.
