Coyote – The process of digging in river-borne gravel by tunneling until bedrock is hit. The tunnel is dug in hopes of finding a rich bedrock deposit deep in the gravel bar. Crevice – A narrow opening, resulting from a crack; a fissure. Cribbing – A timber or plank lining of a shaft; the confining of a wall-rock. CrossCut – A level driven across the course of a vein.
The process of placer mining is the process that is used to find the gold that has been eroded from the lode. Very generally speaking, placer mining involves sifting through gravel to separate the pieces of gold. Placer …
