Location: The occurrence is in Rocky Mountain Creek about 0.2 mile below the stibnite vein called the Lindfors prospect (NM080); it is at an elevation of about 550 feet. The location is shown on figure 4 of Coats (1944). The location is accurate within about 500 feet.
Geology: Rocky Mountain Creek has been mined for gold, and concentrates contain scheelite (NM082). The creek was one of six creeks on the Seward Peninsula that have been identified as possibly containing important amounts of scheelite (Coats, 1944, p. 6). This prospect is on a linear feature mapped from aerial photographs by Hummel (1962 [MF 248]). The linear appears to closely coincide with the scheelite-bearing vein and scheelite-bearing float that was traced from Rocky Mountain Creek southerly for 4,000 feet to Nelson Gulch (Coats, 1944, figure 4). Bedrock in this area is a calcareous schist that gradationally overlies quartzite and schist (Hummel, 1962 [MF 248]).
Workings: Explored by placer mining on Rocky Mountain Creek.
Production: Possibly some placer production of scheelite from Rocky Mountain Creek.
Commodities (Major) - W; (Minor) - Au?
Development Status: None
Deposit Model: Scheelite-bearing quartz-plagioclase veins in schist.
