Introduction
An underground copper mine consisting of two shafts just south of Calumet that worked the Kearsarge Lode.
History
The LaSalle Mining Company was organized in 1906 and began exploration work on the Kearsarge Lode. In 1909 it was acquired by Calumet and Hecla and then bought the Tecumseh and Caldwell properties in 1910. Actual production was from 1910 until 1920, when the mine closed for good.
Production
The mine produced approximately 8 million pounds of refined copper.
For the collector
As with the Laurium Mine less than a half-mile to the north, a large variety of minerals can be found here. The site is especially popular with micro-collectors. It should be noted that the northern shaft (No. 1) is on private property and access is restricted. Shaft No. 2 to the south is accessible.
Note: Coordinates given are for the No. 2 shaft.
