Kivalliq Energy Corporation (TSXV:KIV) announced metallurgical and beneficiation test results for the Angilak Property in Nunavut, Canada. The locked cycle alkaline leaching tests show that sodium carbonate and sodium bicarbonate can be recycled; and yellowcake produced contained 70.0% uranium and low impurity levels.
As quoted in the press release:
Key Point Summary of Metallurgical and Beneficiation Testing
- Locked cycle leach tests confirmed the ability to recycle 100% of the primary alkaline leach reagents;
- Low consumption of ancillary reagents was demonstrated;
- >95% uranium recovery in 48 hour leach cycle;
- Low impurity yellowcake product meets ASTM C976-13 standard specifications;
- Radiometric ore sorting showed potential to reduce dilution with up to 96.7% uranium recovered from 49.2% of the sample mass.
Kivalliq Energy CEO, Jim Paterson, said:
Our team continues to advance and de-risk the Angilak Property by evaluating potential uranium extraction and processing options. The combination of high uranium recoveries and low reagent consumption will have a positive impact on project economics. In addition, the radiometric sorting study demonstrated the potential to remove more than 50% of the waste rock prior to milling.
