VANCOUVER, BC, April 6, 2021 /PRNewswire/ – Blue Sky Uranium Corp. (TSXV: BSK) (FSE: MAL2) (OTC: BKUCF), “Blue Sky” or the “Enterprise”) is happy to announce that the Firm is preparing to execute a second period of approach layout exams for the Ivana uranium-vanadium deposit at the Firm’s Amarillo Grande Job in Rio Negro Province, Argentina. Impartial Technological Advisor Chuck Edwards, P.Eng., will again oversee the testwork application and ongoing procedure design and style to support long term highly developed engineering scientific tests.
“The Ivana deposit is the cornerstone of price at the Amarillo Grande Job. This comprehensive metallurgical program is a vital action to even further advancing Ivana and building supplemental benefit for the project as a complete,” stated Nikolaos Cacos, Blue Sky President & CEO.
The metallurgical testwork will be accomplished at the Saskatchewan Study Council, (SRC) in Saskatoon, Saskatchewan. SRC is 1 of Canada’s foremost suppliers of utilized research, advancement & demonstration, and engineering commercialization, such as certain experience in uranium. SRC is an ISO 9001:2015 accredited corporation. Outcomes of these reports will let refined processing money and running value estimates and will assess the qualities of last uranium and vanadium products. Further plan aspects and a summary of former final results are supplied below.
Chuck Edwards P.Eng. is a distinguished Professional Engineer and metallurgist with in depth experience in Study and Improvement, functions, govt service, consulting and engineering management. He specializes in uranium processing for both alkaline and acid leach crops and was included in the engineering design of all the present uranium facilities in Saskatchewan’s Athabasca Basin, and has labored on uranium initiatives on 5 continents. Mr. Edwards was the System Engineering Advisor at the Saskatchewan Study Council, Director of Metallurgy at Amec Foster Wheeler, and Principal Metallurgist at Cameco Corporation, amid other individuals. Further, he has been a Technical Advisor to the Intercontinental Atomic Electricity Company (IAEA), Vienna Austria considering the fact that 1999 and served as President of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) in 2011-2012. He was the independent certified individual liable for the procedure design and testwork program for Ivana documented in the Preliminary Financial Assessment (PEA) introduced February 27, 2019. Additional specifics on Chuck Edwards track record can be located listed here.
Specifics of Present-day Approach Layout Method
The future experiments will be carried out on a new composite bulk sample consisting of mineralized product from the Ivana deposit. The method unit operations to be investigated in this second established of exams contain:
- membrane filtration and liming
- uranium-vanadium separation by solvent extraction
- uranium and vanadium precipitation
- uranium calcining, and vanadium calcining.
Membrane filtration exams will be carried out with loaded leach answer (liquor) from the alkaline carbonate course of action. The membrane filtration process will generate a few solutions: 1) a concentrated loaded leach liquor, 2) a concentrated reagent liquor for reuse in leaching, and 3) a clean up fluid for washing uranium and vanadium precipitates. The testwork will figure out the exact chemistry and the movement charge of each and every procedure stream.
Liming reduces the bicarbonate concentration in the concentrated loaded leach liquor and also precipitates impurities these kinds of as sulfate ion, iron, thorium and radium. The precipitates are eliminated by filtration. The filtrate is feed to the solvent extraction (SX) circuit. The method will evaluate the consumption of liming reagents and the exact chemistry and the stream rate of each individual approach stream.
The SX circuit separates the uranium and the vanadium into two aqueous answers. The uranium answer is feed to the uranium precipitation method. Similarly, the vanadium resolution is feed to the vanadium precipitation procedure.
Uranium is precipitated as uranium peroxide, also regarded as yellowcake, which is calcined to uranium oxide, which is drummed for shipping and delivery to prospects. Vanadium is precipitated as ammonium metavanadate, also acknowledged as redcake, which is calcined to vanadium pentoxide, which is also drummed for shipping and delivery to clients. The testwork method will evaluate the effectiveness of the precipitation approach for just about every of uranium and vanadium, the consumption of precipitation reagents, the precise chemistry and stream rate of each approach stream, and the purity of the uranium oxide and the vanadium pentoxide products and solutions relative to current market standards.
Summary of Metallurgical Final results to Day
In December 2018, BSK completed a first set of process design and style assessments for the Ivana uranium-vanadium mill. The checks were finished at the Saskatchewan Investigation Council (SRC) in Saskatoon, Saskatchewan.
Based on the testwork, the over-all system plant recovery is 85% for uranium (derived from 89% leach feed preparing restoration and 95% subsequent alkaline leach circuit recovery) and 53% for vanadium (derived from 89% leach feed preparing recovery and 60% subsequent alkaline leach circuit recovery). Recoveries were being established by way of the mineralogical, metallurgical and system engineering check function plan completed by The Saskatchewan Exploration Council (SRC), as detailed in the Blue Sky’s Press Release dated February 7th, 2019.
The do the job in incorporated:
- Mineralogical willpower
- leach feed preparation
- leach feed thickening
- slurry carbonation
- uranium-vanadium leach
- leach tailings filtration
The conventional uranium minerals in the Ivana take a look at sample are carnotite, liebigite, and tyuyamunite. Two extra uranium minerals consist of an oxidized variant of coffinite, called β-coffinite by Blue Sky, and a however un-named one.
Leach feed preparation, employing agitated attrition scrubbing, separates the smaller sized -100 micron diameter uranium-vanadium particles from the larger barren +100 micron diameter particles. The smaller particles represent the leach feed. The more substantial particles are squander, sooner or later to be disposed in mined-out areas. Leach feed preparation boosts the leach feed uranium and vanadium grades by around four moments.
Leach feed thickening gives a appropriate leach feed slurry density for leaching. Slurry carbonation boosts the concentration of leach reactants to a degree appropriate for uranium and vanadium leaching.
The uranium-vanadium leach is an alkaline carbonate (sodium carbonate and bicarbonate) approach. No oxidant was necessary to accomplish the recoveries mentioned higher than.
Leach tailings filtration separates the squander barren leached solids (tailings) from the useful uranium-vanadium loaded leach liquor.
Process Style Conditions
The process details from all of the method layout exams will be made use of to derive course of action layout standards for the Ivana uranium-vanadium mill, permitting much more refined design of the mill and derivation of funds and working price tag estimates for the mill.

About the Amarillo Grande Project
The Firm’s 100% owned Amarillo Grande Uranium-Vanadium Job in Rio Negro Province, Argentina is a new uranium district managed by Blue Sky. The Ivana deposit is the cornerstone of the Challenge and the to start with section of the district for which both of those a Mineral Useful resource Estimate and a Preliminary Financial Assessment have been done. Mineralization at the Ivana deposit has characteristics of sandstone-style and surficial-sort uranium-vanadium deposits. The sandstone-style mineralization is connected to a braided fluvial procedure and suggests the likely for a district-sizing process. In the surficial-form deposits, mineralization coats loosely consolidated pebbles, and is amenable to leaching and straightforward upgrading.
The Project incorporates numerous other target locations about a regional trend, at or near surface area. The place is flat-lying, semi-arid and available calendar year-spherical, with nearby rail, ability and port access. The Firm’s approach consists of delineating sources at various places and advancing the full venture to prefeasibility amount.
