HISTORIC CONTEXT

aka East Rampart Mountain

When Sahinen in 1935 described the Elk Park mining district, little significant mining had been done. Although numerous prospects scattered through the area concentrated on vein mineralization, there has been little additional development even since 1935.

The area is a high mountain valley drained by Bison Creek as it flows through the broad high valley of Elk Park just east of the Continental Divide from Butte. The Butte area to the west and the Basin and Helena area mines to the east were very productive, the area in between, which includes Elk Park, were very minimal mining districts. The Elk Park mining district is underlain by the quartz monzonite of the Boulder batholith with the Elk Park valley filled with recent alluvium. To the east the eroded surface of the batholith is covered by flows of dacite. Pegmatites in the district contain tourmaline and display iron-stained vugs which are possibly the result of pyrite oxidation (Roby et al 1960).

What little production that has occurred in the district came from two lode mines: the Montreal Star and the Sunset. The Sunset, although rarely active, was developed by the Sunset-National Mining Company in 1906 when a gold and silver bearing ore body was found. No production was recorded until 1935 and 1936 when 87 tons of ore reduced to 64 ounces of gold, 128 ounces of silver, and 8 pounds of copper. Although production records are available only for 1940 to 1942, the Montreal Star produced gold, silver, copper and lead ore.

BOUNDARIES OF THE DISTRICT

Sahinen (1935) describes the Elk Park district as being in the vicinity of the Elk Park station on the branch line of the Great Northern Railroad about 18 miles northeast of Butte. Because the district has produced little if any ore, there has been no attempts in the mining literature to categorize the area as a mining district. Roby et al (1960) combines the district with discussions of the Lowland, Beaver Gulch and Nez Perce districts because so little mining has occurred in the area. Figure 1 shows the district as defined by the AMRB (1994) for inventory purposes.

HISTORIES OF SELECTED MINES

Montreal Star and Golden Gate

Situated in section 3 T2N R7W on the west side of Lowland Creek, these claims were located in 1906 by Fred, Henry and Louis Gagnier and Victor Jauron. Production records are available only for 1940 to 1942 when the mine produced gold, silver, copper and lead ore. The mine was opened by a 112 foot shaft with 120 feet of drifting. On the surface, the mine has been developed with cabins, a hoist shack and a rotary kiln and blower (Beck 1986).

Sunset

The Sunset claim (MS#7377) is located in section 3, T2N, R7W. It was developed by the Sunset-National Mining Company in 1906. A 150 ft drift was driven eastward from a shaft to a gold and silver bearing ore body. However, no production was recorded until 1935 & 1936 when 87 tons of ore reduced to 64 ounces of gold, 128 ounces of silver, 8 pounds of copper and 5,983 pounds of lead.
