Precambrian Geology Northern Swayze Greenstone Belt

Precambrian Geology Northern Swayze Greenstone Belt

A number of significant gold occurrences and a past-producing gold mine indicate good potential for gold mineralization in the northern Swayze greenstone belt. The Joburke mine produced about half a million tons of ore grading approximately 0.11 ounce Au per ton. All of the gold mineralization is spatially associated with ductile deformation zones.

In What Rock Formations Can Gold Be Found Sciencing

Apr 24, 2017 Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
