Blue Sky Uranium Reports Positive Concentration Tests for Uranium and Vanadium at Amarillo Grande Project, Argentina

Vancouver, BC / Globe Newswire / May 23, 2018 / Blue Sky Uranium Corp. (TSX-V: BSK, FSE: MAL2; OTC: BKUCF), (“Blue Sky” or the “Company”) is pleased to report that the initial process testing on oxide material from the Company’s Ivana uranium-vanadium deposit demonstrated that simple wet scrubbing followed by wet screening results in the upgrading of metal concentration by approximately 300% for Uranium and 250% for Vanadium.

The ability to efficiently concentrate both the uranium and vanadium represents key strategic factor for developing a low-cost flowsheet for surficial mineralization that is widespread at Amarillo Grande,” stated Nikolaos Cacos, Blue Sky President & CEO. “These very positive results further support our view that we are on the right path to developing a beneficiation and processing framework to support a low-cost uranium-vanadium mining project”.

The Ivana deposit is the cornerstone of the Company’s 100% owned, district-scale Amarillo Grande Uranium-Vanadium Project in Rio Negro Province, Argentina. On April 18th, 2018, the Company filed the NI 43-101 first resource estimate technical report for the project (Thorson et al., filed on SEDAR) and is proceeding to complete a preliminary economic assessment by the end of the year.

These beneficiation studies complement the leach recovery studies presented on January 22nd, 2018, (see News Release filed on SEDAR). The studies were completed on a single composite sample believed to contain primarily carnotite (a uranium-vanadium oxide) mineralization, which is the most common style of mineralization found at Amarillo Grande. Ongoing metallurgical test work includes detailed mineralogical characterization for primary and oxide mineralization types and physical beneficiation and recovery test work on mineralized material containing primarily coffinite (+ uraninite) from the Ivana deposit.

Study Details:

The beneficiation metallurgical studies were completed on a single composite sample created from four RC samples with uranium-vanadium mineralization as carnotite coating fine to coarse poorly-consolidated sandstone and conglomerates with an average grade of 459ppm U3O8 and 537ppm V2O5. The beneficiation technique included 20 minutes of wet scrubbing inside a bottle rolling system followed by 300 micron wet screening. As a result, the fine coating of carnotite over the grains or pebbles of the sedimentary host rock were separated and pre-concentrated. Recoveries include 93% for uranium and 74% for vanadium, with an enrichment factor of 311% for Uranium and 247% for Vanadium. The reject material (gangue) returned grades of 23 ppm U3O8 and 196 ppm V2O5.
