The Mining Bureau has separate programs for hard rock exploration and hard rock mining. Hard rock exploration requires a license to perform drilling and trenching and other activities to determine if an economical mineral resource is present. Hard rock mining can occur under a Small Miner Exclusion Statement (SMES) or under an Operating Permit.

A dry mining operation feed preparation plant's first duty is to slurry the ore stream, after which the downstream processes are common for both dredge and dry mining operations. Ore slurry usually is screened to remove coarse particles, usually at about 2 mm. Coarser oversize, e.g., +10 mm, is hauled away from land-based concentrators by ...
