Shoshone's Weber Mine
Initial discoveries of mineralization in the Lakeview District were made in 1888 near the site of the Weber Mine. The Weber, known at one time as the New Rainbow Mine, lies on the Weber Shear, which also hosts the Keep Cool Mine.
The Weber Pit in the Lakeview District
Three levels were developed in the underground mine. The main level was developed along the footwall and hanging wall along strike with the shear zone. The shear itself was untouched. Limited development was done on the shear in the two additional levels.
Development was shifted to surface mining operations following the development of the underground mine. In 1978 a bulldozer trenching discovered an second surface zone of mineralization 2,000 ft northeast of the original pit. It exposed a vein 10-12 ft. wide and 135 ft long. This vein was mined during the early 1980s.
Production records of the Weber indicate that it has been a primarily silver-lead mine. Shoshone is planning exploration of the Weber during fall 2007/Spring 2008.
