Case Study: Placer Gold Mining

1988
The very word ‘gold’ conjures up very different pictures to the other minerals discussed in this book. Countless Hollywood pictures have inscribed the images of the 1849 California gold rush firmly on our minds not as deep mines but as the ‘Old Timer’ painstakingly panning for the gold in the river. Whilst much of the world’s supply now comes from deep

Origin of placer gold nuggets and history of formation of glacial gold placers, Gold Creek, Granite County, Montana

Economic Geology, 1994
Placer gold along the upper portions of Gold Creek, near Deer Lodge, Montana, occurs in Pliocene(?) fossil alluvial placers, Pleistocene till, and alluvium. The upper Gold Creek placers yielded an estimated 175 to 200 kg gold during 1890 to 1990. The gold probably originated in veins, skarn, or replacement deposits in Paleozoic and Mesozoic sedimentary

Placer-lode gold relationships in the Nansen placer district, Yukon

2016
Compositional studies have been undertaken on gold particles recovered from hypogene ore, eluvial material and placer samples in and around the Klaza property. These data have been correlated with previous descriptions of in situ mineralization to elucidate placer-lode relationships and systematic change in gold compositions between porphyry and ...
