Black Hills Most Complete Original Mining Experience Keystone, SD.
Big Thunder Gold Mine originally named Gold Hill Lode was discovered in 1892 by two German immigrant miners, W.B. Krupp and J.A. Engle. They migrated across America separately but met in Keystone, SD. Their common language connected them and they eventually became partners.

Krupp and Engle started mining the hill up high, anticipating an outcrop of indicator minerals. Unable to strike a rich vein, the miners moved down the hill to the current mine location. They were trying to intercept the Lucky Boy vein. Lucky Boy Mine was located downstream from Big Thunder, on the neighboring claim adjacent to the first half of the Big Thunder property, near Keystone, SD.
The miners studied the direction and angle of the Lucky Boy ore body.
They skillfully devised a plan to intercept the ore body by driving an adit, or access shaft, into the hill at the current mine entryway.
In Black Hills Gold Mining History, miners first drilled holes in the solid rock using only hand equipment. Then they placed powder in the drill holes to blast the rock loose.
Krupp and Engle used a drilling process called double jacking. One miner held a steel drill bit while the second miner pounded it with a sledgehammer. A series of drill holes spanned six to eight feet in the shape of a butterfly with outstretched wings. This butterfly pattern allowed explosives to excavate a safe square with very little fracture to the sides of the tunnel. A properly done blast would completely fracture the ore yet maintain integrity of the interior mine.
The butterfly drill pattern was carefully executed. Miners fired the four drill holes in the center of the blast face first, followed by the rest of the charges. This sequence fractured the rock and blew out a cone of ore from the center of the surface. The next ring of explosives directed energy toward the center area previously removed in the blast sequence. This energetic process fractured the ore more efficiently and maintained the outer wallsrsquo reliability. Firing all the drill holes simultaneously would have threatened the integrity of the walls, leading to possible cave-ins.
Big Thunder is one of the safest mines in Black Hills Gold Mining History because the adit, or access shaft, is cut in solid rock. The rock stability allowed miners to use very little timbering.
