Blue Sky Uranium Reports Positive Metallurgical Results from Ivana Target, Amarillo Grande Project, Argentina
22 Janvier 2018 - 3:25PM
Blue Sky Uranium Corp. (TSX-V:BSK) (FSE:MAL2)
(OTC:BKUCF),
("Blue Sky" or the "Company") is
pleased to report the initial metallurgical results for
carnotite-mineralized material from the Ivana target area have
yielded recoveries of more than 95% for uranium using alkaline
leach processing.
“High metallurgical recovery is a key factor to
support low cost uranium production from surficial deposits such as
Amarillo Grande,” stated Nikolaos Cacos, Blue Sky President &
CEO. “The use of a low-cost recovery process and the ability to
recover vanadium also significantly enhances the potential of a
project.”
Ongoing metallurgical test work includes
physical beneficiation assessments, as previously carried out on
samples from the Anit target area (see Blue Sky news release dated
February 7th, 2011), and initial test work on coffinite (+
uraninite) mineralized material. The Anit preliminary beneficiation
test work demonstrated that a very simple wet screening method
could be utilized to reject coarse clastic material, producing a
lower-mass concentrate containing a high percentage of the in situ
uranium.
Study Details:
The metallurgical studies were completed on a
single composite created from four samples with carnotite (a
uranium-vanadium oxide) which is the most common style of
mineralization found at Amarillo Grande. The composite was
characterized as a fine to coarse poorly consolidated sandstone
with average grade of 408ppm U3O8 and 512ppm V2O5. The alkaline
leaching study was carried out using 492g of sample in 1kg leaching
solution with 50 g/L Na2CO3 (sodium carbonate) and 20 g/L NaHCO3
(sodium-bicarbonate) at 80 °C with constant agitation for 8 hours.
Sampling was done every hour and the uranium and vanadium content
related to the initial pregnant solution were estimated. The
results indicate that 95% of the uranium is leached in 2 hours and
60% of the vanadium in 3 hours, with estimated consumption of 40
kg/t sodium carbonate and 8 kg/t of sodium bicarbonate.
The studies included an assessment of uranium
and vanadium adsorption by kinetic ionic interchange using Purofine
PFA 600/4740 resin over time until reaching equilibrium. The
“mother” solution generated by the alkaline leaching study
underwent magnetic agitation at room temperature, where the resin
was activated with a 1M sodium- bicarbonate solution. The results
indicate that vanadium is adsorbed faster than uranium, at 30 and
80 minutes respectively.
The study was completed by INVAP S.E. at their
facilities following ISO 17025 standards, and the analytical
methodologies used traceable certified standards and verified
devices. INVAP S.E. is an Argentine company based in Rio Negro
province, devoted to the design and construction of complex
technological systems, with more than 30 years in the domestic
market and more than twenty in the international scene. The company
has a long track record of success for global clients in the
nuclear sector.
About the Amarillo Grande
Project This new uranium district was first identified,
staked and underwent preliminary exploration by Blue Sky from 2007
to 2012 as part of the Grosso Group’s strategy of adding
alternative energy focus to its successful portfolio of metals
exploration companies. The proximity of several major targets
suggests that if resources are delineated a central processing
facility would be envisioned. The area is flat-lying, semi-arid and
accessible year-round, with nearby rail, power and port access.
Mineralization identified to date at Amarillo
Grande has characteristics of sandstone-type and surficial-type
uranium-vanadium deposits. The sandstone-type deposit is
related to a braided fluvial system comprising a potentially
district-size “roll front” system. Uranium minerals are present in
the porous of poorly-consolidated sandstones and conglomerates. In
surficial-type uranium deposits, carnotite mineralization coats
loosely consolidated pebbles of sandstone and conglomerates.
Carnotite is amenable to leaching, and preliminary metallurgical
work at the project indicates that the mineralized material can be
upgraded using a very simple wet screening method. The
near-surface mineralization, ability to locally upgrade,
amenability to leaching and central processing possibility suggest
a potentially low-cost development scenario for a future
deposit.
