Copper mining in Michigan In the 1850s, mining began on stratiform native copper deposits in felsite -pebble conglomerates and in the upper zones of basalt lava flows (locally called amygdaloids ).
Basalt is frequently mined in a surface mine, or quarry. The majority of basalt is used a aggregate (gravel) in making concrete and asphalt paving. Typically, boreholes are drilled in the rock with power drills, boreholes loaded with explosives, and fired- producing the first breakage.
The mine produced 27.8 million carats (1 ct = 200 mg; 5 carats = 1 gram) of low grade diamonds in 1993-1994. Because of the high rate of production at Argyle, mining operations will end within the next few years. The mines at Kimberley, South Africa have produced a total of more than 200 million carats since the 1870s.
