The Algonquin is an old mine. It was one of the earliest mines in Montana’s Philipsburg district. By 1877, it was being worked by a 10-stamp mill for silver with minor amounts of gold. The mill proved inefficient, and a new 20-stamp mill was soon installed. Reportedly, there was an 80-stamp mill here, but I didn’t see it. Perhaps it was the huge mill nearby at Granite?
