Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020005 Forest or Resource Area: DEERLODGE Owner: N Impact: Report: Snyder This has been the only productive mine in the proposed Tobacco Root-Middle Mountain Wilderness area, so was the subject of a detailed investigation by O'Neill and others (1983). The mine follows a west-striking, south dipping quartz-pyrite-copper carbonate vein within a shear zone 3.3 feet thick enclosed in Archean gneiss. The vein is at least 760 feet long, and is explored by approximately 1500 feet of workings from 5 portals. Production in 1934 was 10 oz of gold, 75 oz of silver, and 326 lbs of copper. A stockpile sample carried .641 oz/ton gold, 6 oz/ton silver, and .46% copper. Presently there are two substantial discharges from the lowermost adits. However, the dumps are composed of unaltered gneiss with no visible sulfides, and dump samples showed no to a trace of metals (O'Neill and others, 1983). The Snyder Mine is located at the head of the west fork of the South Boulder River in the Tobacco Root Mountains. Mining consisted of exploiting gold in quartz veins with little or no sulfides present. The mine consists of at least four adits. The lowest adit is comprised of two openings, both of which discharge water. Both discharges sink into the dump and re-appear at the base and discharge into the main stream. Up-stream of the confluence of the adit discharge and the main stream is a fifth, un-identified adit. While there is no discharge directly out of the adit, the main stream runs along toe of the dump and may be influenced by the mine. JSNS10L: Located at the discharge point of the south caved adit. The sample will be analyzed for Dissolved Metals only. Discharge will be measured by the dam-pipe-bucket stopwatch method. JSNS20L: Located at the discharge point of the north caved adit. The sample will be analyzed for Dissolved Metals only. Discharge will be measured by the dam-pipe-bucket stopwatch method. JSNS30L: Located below the confluence of the adit discharge streams and the main stream. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by the dam-pipe-bucket stopwatch method. JSNS40L: Located on the main stream below the un-identified adit and above the road crossing. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by the dam-pipe-bucket stopwatch method. |
