The content of gold within these deposits is largely variable, and can be a factor in the economic value of the deposit. The gold contents of all deposits averages 0.41 g/t Au, with the majority of worldwide deposits averaging less than 1 g/t Au. [2] The occurrence of native gold mineralization. Example from Kalgoorlie Australia.
The highest-grade samples contained 138 grams of gold per ton of ore, surpassing the typical benchmark of eight grams for high-grade deposits. The initial exploration discovered 300 tons of gold ...
