Characterisation of alluvial gold exploration data to improve gold

This study uses exploration data to optimise overburden thickness, cut-off grade and stripping ratio at some alluvial gold mines in the Kibi mining district to improve gold recovery in Ghana. The specific objective is to determine sampling location, overburden thickness, gravel thickness, gravel grade and gold contents. Secondary data are from 48 The Klondike gold rush of 1896-1899 was the largest and most storied gold rush in history. It is estimated that over 100,000 gold seekers migrated to the Arctic territory from places like San Fransico and Seattle.

The Archaeology of the Gold Dredge: The Final Phase of Placer Mining

Deep mining, with hand-drills and blasting, exposed veins of gold that was then brought to the surface for processing (Glass 1985, 421–423). One early example, at Gold Hill in North Carolina, saw miners sink a shaft 970 feet deep with 894 feet of levels following veins (Glass 1985, 425).
