These companies are doing what is referred as hard rock mining in which they are digging open pits up to 1,500 deep to blast granite and quartz veins where the gold is located. This is a very expensive and labor intensive method, but through their underground geologic surveys, theyve proven large quantities of gold to exist and therefore can justify the heavy capital investment.
