Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020006 Forest or Resource Area: DEERLODGE Owner: N Impact: Report: Boulder Chief-Ida M. These two sites are treated as one mine because they are located within 1000 feet of each other on the same shear zone. This shear zone trends N82W 79NE and appears to be continuous for at least 1500 feet. Workings consist of the Ida M. adit (caved) with about 800 feet of workings, the Boulder Chief with one locked adit and one caved 350 foot shaft with four levels (unpublished information, MBMG files) and approximately 4000 feet of workings, and a large surface cut along the shear zone. The property is located at the contact between Elkhorn Mountain andesite and Boulder Batholith quartz monzonite. Most of the material on the dumps is quartz monzonite with quartz, sericite, and pyrite alteration products. Becraft and others (1963) and Roby and others (1960) provide some background information. Apparently lead, silver, and copper were the main commmodities, with most production from 1913-1917. The remaining badly eroded gravity tailings from the Boulder Chief mill suggest one to two thousand tons of ore was mined. The vein contained the typical Boulder Batholith assemblage of quartz, pyrite, galena, sphalerite, and arsenopyrite. Weak radiactivity was measured on the east end of the vein by Becraft and others (1963), who estimated that it contained .01% uranium. Our own scintillometer measurements of the dump material were only slightly anomalous. Today, both adits discarge water. In addition, tailings and dump material from the Boulder Chief have been carried over 700 feet downslope by runoff. An estimated 7000 tons of dump material remains at .042 oz/ton Au, 1.52 oz/ton Ag, .025% Cu, .97% Pb, and .22% Zn. A composite sample of the 1000-2000 tons of tailings carried .018 oz/ton Au, 4.34 oz/ton Ag, .055% Cu, 2.32% Pb, and 3.87% Zn. The entire affected area is on USFS lands. |
