Virginia Energy Resources Inc. (TSXV:VAE) reports the initiation of metallurgical studies for the Coles Hill project in Virginia.
The press release is quoted as saying,
The Preliminary Economic Assessment relied upon previous metallurgical work completed by Colorado School of Mines Research Institute and Hazen Research in 1982, which focused on conventional uranium processing methods of that era. The historical metallurgical testing included agitated leaching of ground core samples with sulfuric acid and with sodium carbonate plus sodium bicarbonate. Because of high acid consumption, alkaline leaching was the recommended option despite showing only an 83.5% recovery rate compared to a 94% recovery rate with acid leaching.
