Agency: NF Region District: R1 Ranger District: PHILIPSBURG Forest Service Tract: Watershed Code: Forest or Resource Area: DEERLODGE Owner: M Impact: V Report: Forest Rose The largest producer in the Dunkleburg District, the Forest Rose contains at least 3500 feet of workings over a 400 foot vertical range. The ore occurs on the nose of the north-plunging Dunkleburg Anticline where the Kootanai gastropod limestone intersects an axial plane fault zone (Popoff, 1953). Mineralization replaces the limestone and can be followed for 1000 feet along plunge. The ore contains galena, sphalerite, pyrite, quartz, and calcite, and ore mined averaged 4.0% lead, 4.0% Zn, and 3 oz/ton Ag. The grade decreases rapidly away from the crest of the fold. Both Wasa ore and Forest Rose ore were processed at the Forest Rose Mill. Combined production from both mines totalled 59 oz of gold, 153,624 oz of silver, 106 tons of copper, 1465 tons of lead, and 2540 tons of zinc (Northern Testing Laboratories, 1983). Like the Wasa, the mine was active in the early 1900's and again from 1941-1947. The main adit is caved and discharges was into the dump and tailings below. Northern Testing (1983) estimated the dump, on private land, contains 18,200 tons of .005 oz/ton gold, .4 oz/ton silver, .020% copper, .21% lead, and .63% zinc. Forest Rose Mill This 65-90 ton per day flotation mill operated from 1940-1947, and processed ore from both the Wasa and Forest Rose (Popoff, 1953). Using a detailed topographic map they created, Northern Testing (1983) calculated that the tailings were comprised of 124,500 tons of material with an avaerage grade (from 3 samples) of .017 oz/ton gold, .63 oz/ton silver, .038% copper, .377% lead, and 1.04% zinc. They noted that water from the mine discharge ran across the top of the ponds. In 1992, there was not enough mine water to make it to the tailings, but springs emerged from the base of the tailings. |
