Much of the gold recovered from the creek in the primary yr of operation of the dredge, was discovered inside 1 to 3 feet of bedrock, with the best concentration discovered throughout the 6 inches above bedrock. The Award introduced at the PDAC in Toronto to recognize the accomplishments of Mark Bronston, Richard Garnett, Paul Graff, W. Dan Hausel, Bruce Hickok (RIP), Toni Hinderman (RIP) and Robert Retherford. The upper 3 toes consisted largely of loam (sand, clay and gravel) which was thought to be barren of gold and was rejected by the Fisher Dredge.

Fisher Firm constructed a concentrating plant with trommel and mined with an unattached dragline in order to dredge 6 miles of Rock Creek from Atlantic Metropolis to the Mormon Cemetery. In 1884, significant gold placer operations have been proposed and the Granier ditch was constructed to haul water from Christina Lake (12 miles northwest) to South Pass. Portions of Rock Creek had been mined from 1933 to 1941. Pre-1933 gold placer mining operations on Rock Creek have been likely localized hydraulic operations designed to clean gold from slopes of adjacent hill sides.

Startup of hydraulic operations did not occur till 1890. In 1891, 6,720 ounces were recovered. Whole historical gold production from Arizona is about sixteen million ounces since data were stored beginning within the late 19th century. The common soil depth for Rock Creek was reported as 10 feet and ranged from 9 to 12 ft deep. The gravels were 6 to 10 toes deep, and gold occurred as flatten nuggets and flakes close to bedrock and in the sandy and gravel layers overlying thin clay-wealthy, false bedrock, zones. The lode stands nearly vertical and from this mine degree, it continues upward to the surface. This can be a specimen discovered in the Mary Ellen mine by Steve Gyorvary who donated it to the Wyoming Geological Survey (before it grew to become a den of scum from 2004-2008) and that i photographed it utilizing a binocular microscope (the size is probably not in meters as I like to inform some people, it's a millimeter scale). Determine 3. Steve Gyorvary stands within the mined out portion of the Carissa lode on the 400-foot-level. This a part of the excessive-grade lode was mined in the past and the empty area provides a pleasant perspective of the lode’s perspective. Steve Gyorvary at Atlantic City, Wyoming.

Pfaff, B.C., 1997, Fantastic Gold. Primarily, all of the loam piles stay untested for gold content material and supply a potentially massive useful resource if the effective gold can be effectively recovered. Based on the profitable nugget recovery in the Fisher gravel piles by varied prospectors using metal detectors, there was a usually poor nugget recovery effectivity of the Fisher operation. The mined gravel piles additionally contain some rejected gold. Even so, the nearer the placers lie to the known belt of shear zones, the larger the chance coarse gold (nuggets) can be found in stream gravel. Typically pyrite will oxidize and leave silica wealthy ridges that look porus which can be known as boxworks. As you discover mine names, search the net for those mines. In June 1867, a wealthy lode gold deposit was found alongside Willow Creek and the mine was named the Carissa. At at present's gold prices, this 40 million ounce deposit is worth about $70 billion.
