Canada-based Kivalliq Energy has reported high purity uranium deposits at the Lac 50 Trend within its flagship Angilak property in Nunavut Territory.
Optimized results from preliminary metallurgical tests for the Lac 50 Trend indicate that 94.1% of uranium can be extracted in 48 hours and 95.9% of uranium extracted in 72 hours.
The company also reported uranium value of 71.9% for a final yellowcake product from preliminary yellowcake precipitation test.
The Saskatchewan Research Council (SRC) initiated metallurgical testing program at the trend in June 2012, which was designed to examine uranium alkaline leaching optimization and evaluation of purity levels.
Nuclear laboratory services provider AMEC’s metallurgy director Chuck Edwards stated that the final yellowcake produced from the leach solution was a low-impurity product.
"Available final yellowcake assays fell below the Maximum Concentration Limit Without Penalty of ASTM C967-13, Standard Specification for Uranium Ore Concentrate.
"The alkaline leaching process proposed for the Lac 50 Trend uranium deposits is similar to that used successfully for almost 30 years at Eldorado Nuclear’s Beaverlodge mill in northern Saskatchewan," Edwards added.
The Lac 50 Trend hosts an inferred resource of 2,831,000t of uranium oxide grading at 0.69% U3O8 for 43.3 million pounds.
