Location: The Bunkhouse prospect is at an elevation of about 2,950 feet, on the northwest bank of Bryn Mawr Creek. The map site is in the SW1/4 of sec. 34, T. 19 S., R. 11 W., of the Fairbanks Meridian. The location is accurate to within 1,000 feet.
Geology: The Bunkhouse prospect is about 2,500 feet north-northeast of the Golden Zone (HE043). The country rocks at the prospect are Triassic redbed sedimentary rocks, cut by the Bryn Mawr fault. The deposit consists of fault-controlled quartz stockwork veins and pods containing pyrite, arsenopyrite, and marcasite(?). The country rocks adjacent to the veins are bleached and argillized (unpublished report by Addwest Minerals International Ltd., 1997). Zones of disseminated sulfides up to 15 feet thick in the altered country rock contain up to 0.2 ounce of gold per ton (unpublished drill hole data). The Bunkhouse (and Lupin, HE038) deposits contain less base metals and more silver, arsenic, antimony, mercury and bismuth than the other deposits at and near the Golden Zone mine. Their ore mineralogy suggests an epithermal depositional environment.
Workings: The Bunkhouse deposit was discovered by trenching and soil sampling. Five drill holes, totaling 2100 feet, have tested the prospect to a depth of 500 feet (unpublished report by Addwest Minerals International Ltd., 1997).
Age: The Bunkhouse deposit may postdate the Late Cretaceous - Early Tertiary deposit at the Golden Zone mine (HE043).
Alteration: Zones adjacent to the veins are bleached and argillized.
