Named for the blacksmith Fred LaRose who discovered the site in the summer of 1903. The mine named after him went on to produce over 26 million oz. of silver and 1 million lbs of cobalt. Veins from the mine are visible on the cliff faces in the north end of Cobalt.

"The story seems unlikely, but because it is such a good tale it has become widely publicized as part of the folklore that distinguishes this community. The stocky smithy, working at his forge one evening, noted a red fox snooping about the camp. Letting fly his hammer he missed the animal but cracked off a piece of rock, exposing the glitter of silver. Irrespective of the means of obtaining the sample, its reality is unquestionable as it yielded the LaRose [sic] mine." [Grice (1989), page 87]
