Exploration & Mining Services

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 mine tailings or to determine viability of reclamation of a former mine site. The demand for this type of drilling has grown in recent years as new and less expensive mining techniques have made it feasible to mine previously uneconomical sites and the utilization of former mining sites has gained importance.  Our drilling services require a high level of expertise and technical competence because the samples extracted must be free of contamination and accurately reflect the underlying mineral deposit, geology/hydrology and ground conditions.
