Geology of Uranium Deposits - World Nuclear Association
Where uranium is recovered as a by-product of gold mining, such as at Witwatersrand in South Africa, the grade may be as low as 0.01%U. In uranium-dominant deposits such as at Elliot Lake in Canada average grades range as high as 0.15%U.
The deposits comprise black mafic mylonite, black shale, shale, quartz diorite, basalt, basaltic andesite and felsic volcanics. Gold mineralisation displays no obvious association with sulphide content, quartz veining or alteration (graphite and sericite).
A critical measure of the viability of oil shale as an energy source lies in the ratio of the energy produced by the shale to the energy used in its mining and processing, a ratio known as "Energy Returned on Energy Invested" .
