Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine.

This drilling techniques designed to capture samples for geological evaluation for ether existing mines (grade control, pit design) or for greenfield deposits (resource definition). Drilling methods used include coring, and RC.

Mineral exploration, such as core boring, requires rapidly hydrating bentonite to ensure:
– Stability of the walls of the shaft and facilitate recovery of detritus
– Lubrication and easy recovery of drilling equipment
– Formation of a high-quality impermeable panel that allows maximum prevention of fluid loss
