Location: The placer ground at Little Pup is located in the lower section of Little Pup Gulch, a tributary of Poorman Creek. These coordinates correspond to location 30 of Cobb (1972 [MF405]) and place the Little Pup placer ground in section 20, T. 16 S., R. 17 E., Kateel River Meridian. The location is accurate.
Geology: The bedrock underlying the pay streak of Little Pup is phyllite, although schist is present at the mouth of the gulch (Mertie, 1936). There is very little gravel in Little Pup, and it is covered by about 60 feet of muck (Brooks, 1915). A deep mine was operated in 1914 (Brooks, 1915). A stretch about 450 feet long was worked out before 1933 (Mertie, 1936). The pay streak was about 5 to 18 feet wide and 3,000 feet long and carried good gold values (Mertie, 1936). The ground ran as much as $2.25 (gold at $20.67 per ounce) per square foot of bedrock. Production was reported to be about 230 ounces of gold (Mertie, 1936). The last mention of placer mining was in 1933. Exploration on Little Pup may have occurred in 1934 and 1935 (Mertie, 1936).
