Exploration and Mining | Gregg Drilling LLC

Exploration and Mining Gregg Drilling can conduct specialized geotechnical drilling to extract samples from a site for exploration/mining purposes. These samples can be utilized to determine if and/or what type of mineable mineral deposits exist, to assess whether it would be economical to mine, to assist in the management and evaluation of ...

Using Test Drilling to Sample Gold Deposits ...

Test drilling for gold is an important step in prospecting and eventually commercially mining for gold. Test drilling is done to get a continuous sample of the bedrock of a given gold project. The sample is then tested to determine if there is gold in the project area and to estimate the amount of gold that can be mined in the area.

Cost Models of Theoretical Mining Operations | CostMine

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order- of-magnitude estimates.
