Location: 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).
Geology: 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.
Workings: In 1998, five reverse circulation holes were drilled in the area to test anomalous soil sample values (Freeman and others, 1998).
Alteration: Sericitic alteration with silicification was found along the entire length of one drill hole.
Production: None.

Commodities (Major) - Au; (Minor) - Ag
Development Status: None
Deposit Model: Fort Knox type, intrusion-hosted low-grade gold deposit.
