Location and accuracy The location given is on one of five drill holes which covered an area of approximately 1 mile by 0.5 miles on the ridge between Too Much Gold Creek and Moose Creek (Freeman and others, 1998).

Geologic setting

Geologic description

Five holes were drilled in the area to test anomalous soil values and follow up on altered and weakly mineralized dikes exposed on the Governor mine dump (ARDF no. LG172) and a nearby trench (Freeman and others, 1998). One hole intercepted 50 feet of 0.028 ounces of gold per ton. Another hole intersected thick intervals of anomalous gold but did not find significant grades. A third hole intercepted 55 feet of 0.028 ounces of gold per ton, and 0.843 ounces of silver per ton. The two other holes did not intersect significant gold values.

Mineral deposit model Fort Knox type, intrusion-hosted low-grade gold deposit.
Alteration of deposit Sericitic alteration with silicification was found along the entire length of one drill hole.

Production and reserves

Workings or exploration In 1998, five reverse circulation holes were drilled in the area to test anomalous soil sample values (Freeman and others, 1998).
Indication of production None
Production notes None.
