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.

Concentrates: MORE GOLD LESS WORK! Our concentrates come from the amount of dirt we take from our gold mine and run through the trommel. All the lighter sand is washed out while all the gold and the heavy sand stays in the sluice. This is a natural process no gold is taken out or added! 15 gallons of ore condensed into one gallon is $45.00
