Prospecting and Mining Old Mine Sites

December 2016
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.

Epithermal Ore Deposits Associated With Tertiary Volcanism—And the Feasibility of Metal Detecting for Them

December 2000
