Kivalliq Energy Corporation (TSXV:KIV) reported positive metallurgical results from ongoing metallurgical and beneficiation studies for the Angilak Property in NunavutTerritory. This update summarizes preliminary results from work performed on the Lac 50 Trend deposits, including: metallurgical testing of the J4 and Lac 50 zones as well as characterization studies related to optimal ore sorting methods.
As quoted in the press release:
“Results from ongoing metallurgical work at Lac 50 are encouraging,” stated Chuck Edwards, Director of Metallurgy at AMEC. “Optimizing sulphide recovery, plus improvements to alkaline leach kinetics using oxygen as oxidant, could have a positive impact on reducing costs associated with potential treatment options.”
Key Point Summary:
- J4 Zone flotation achieved an optimum sulphide recovery of 99.2% in alkaline solution at a grind size of 100% passing 140 mesh (106 µm).
- Positive alkaline leach results on J4 Zone indicate rapid uranium extraction: 92.3% in 12 hours, 95.2% in 24 hours and 96.7% in 48 hours.
- Using improved alkaline leach parameters defined by the J4 Zone testing, retesting of the 2012 Lac 50 composite upgraded the leach extraction of uranium to: 91.7% in 12 hours, 95.1% in 24 hours and 96.4% in 48 hours. (previous results released February 28, 2013)
- J4 Zone sulphide flotation and alkaline leach results are consistent with other Lac 50 deposits.
- Preliminary ore sort characterization of rock specimens from Lac 50 deposits indicates that radiometric sorting will be very effective. Radiometric characterization analysis demonstrates a 56% reduction in mass with 98% U3O8 recovery.
