prospecting of lime stone deposit through core drilling


GEOLOGY OF FLORIDA LIMESTONE AND SAND DEPOSITS …

Mining companies are likely to find two types of rock when prospecting in Florida for new deposits: relatively hard limestone and soft limestone. The hard limestone will yield a range of high value products including aggregates and other finished stone materials. The soft limestone will be used for lower value products such as limerock base, shell

Gold Prospecting | How to Find Gold in the United States

Hydrogeochemical prospecting for gold: Groundwater collected from wells, springs, and drill holes may provide clues to the presence of subsurface gold deposits. As groundwater flows through the deposit, minute amounts of gold are leached from the rocks. These can sometimes be detected in groundwater samples collected from wells located down gradient from the deposit.
