We read about an old mine deep in the forests of Idaho with the remains of a 10-stamp mill and, more interestingly, a "portable" smelter.
Smelters are rare, and it's even rarer to find one deep in the backcountry. And I've never even heard of a portable one.
The mine was first worked for silver in the 1880s. A portable smelter was brought to the site in the 1900s with a significant effort. It was fitted with a uniquely designed water jacket. Reports state, however, that it was unsuccessful, so a 10-stamp mill was built next to it to process the ore. The mill and mine were worked only intermittently over the years. Most of the smelter and mill was dismantled during the Depression of the 1930s.
The mine adit is gated, but you can see that it is caved in a short way anyway.
I've been asked not to give directions to this mine. Please enjoy my photos below.
