Mill A and B
By editor
Granite (near Philipsburg), Granite County, Montana
Beside the Ruby Shaft, the Granite Mountain Mining Company built two mills—A and B—housing seventy stamps between them. Stamp mills crushed ore so metal could be separated by mercury amalgamation. They were loud. They were dusty. They ran six days a week, which is another way of saying the mountain rarely slept.
When Ruby Shaft production outran A and B in 1889, the company built Mill C at Rumsey to take the overflow. The sequence is the biography of a successful mine: dig faster, crush faster, build another mill. The foundations and interpretive signs above Philipsburg still sketch that industrial logic for visitors who hear only wind where seventy stamps once argued with the hillside.
