The Wedge mine has just struck a very rich vein of ore at the 350-foot level in the west drifts. It is different from anything found here before, of a sulpheret character, but will mill $200 in free gold. Mr. Cook is here in the interests of the Barstow Mill, securing low-grade ore that will not pay to mill here.
Montana Gold - The GOLD HUNTER
Gold-bearing gravel was discovered in Silver Creek in western Montana in 1864. The pay streak was 30 to 50 feet wide and 15 to 20 feet deep and had a relatively high silver content. Soon gold was found in the adjacent hills in gold-silver quartz veins in metamorphosed Belt Series rocks.

A gold mill houses the equipment necessary to remove gold from the surrounding waste rock, either by concentrating it or by mechanically separating it. The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material.

Gold is part of a group of metals called noble metals, which include gold, silver, and platinum; they all resist chemical action, do not corrode, and are not easily changed by acids.
