VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 18, 2017) – Blue Sky Uranium Corp. (TSX VENTURE:BSK)(FRANKFURT:MAL2)(OTCQB:BKUCF)(“Blue Sky” or the “Company”) is pleased to report Phase I Extension reverse circulation (RC) drilling results for the Ivana target and the Phase I results from the remainder of the Amarillo Grande uranium-vanadium project, in Rio Negro Province, Argentina (see Map 1: https://www.blueskyuranium.com/assets/news/2017-09-18-nrm1-bsk-g97x6f.pdf ).
At the Ivana target, RC drilling on the eastern flank of the previously-reported Phase I drilling area (June 19, 2017 News Release) has defined a strongly mineralized corridor that extends more than 2 kilometres in a northeast direction, is between 200 and >400 metres wide, up to 20 metres thick, and is open to expansion to the southeast and to the north (see Map 2: https://www.blueskyuranium.com/assets/news/2017-09-18-nrm2-bsk-g97x6f.pdf ). This largely continuously mineralized zone includes a higher-grade core zone over one kilometre in length, which includes drill intercepts of up to 3,136 ppm U3O8 over one metre (AGI-0100). Strong uranium grades are also present within the interpreted southeastern extension (942ppm U3O8 over one metre in AGI-0124); and, the northern extension (817ppm U3O8 over one metre – AGI-0138).

“These results represent a significant new uranium-vanadium discovery,” stated Nikolaos Cacos, Blue Sky President & CEO. “We have always held the belief that Blue Sky’s Amarillo Grande project, covering 269,000-hectares, has district-wide potential for uranium-vanadium discovery – and these results confirm that. We thank our technical team, led by Guillermo Pensado, and our shareholders for their patience and perseverance.”
Most of the uranium-vanadium found to date at Ivana and elsewhere on the Amarillo Grande property has consisted of carnotite mineralization in a surficial deposit type setting. Examples of surficial uranium deposits include Langer Heinrich in Namibia, which has Proven and Probable ore reserves and stockpiles with an average grade of 471 ppm U3O8(1) and in in the 9 months ending in March 2017 had C1 unit cash costs of US$17.51/lb U308.(2) In some of the recent strongly mineralized holes at Ivana, potentially primary mineralization was observed and the deposit style appears to include more characteristics of sandstone-type deposits. Sandstone deposits represent approximately 18% of world uranium resources, with grades of typically 0.05 to 0.35% U. These deposits are a leading source of uranium production in Kazakhstan, the USA and Niger (3).
The Company has commenced additional geophysical surveys and RC drilling to expand the strongly mineralized corridors identified to date at Ivana. Metallurgical testwork is also progressing.
Drill Program Technical Summary:
The 269,000-hectare (~665,000 acre) Amarillo Grande project spans a 140-kilometre long trend along which a number of areas of uranium-vanadium mineralization have been identified. From northwest to southeast there are three primary outcropping target areas named Santa Barbara, Anit and Ivana. This Phase 1 and Phase 1 extension RC drilling program included a total of 3,730 metres of RC drilling in 256 holes. A complete list of weighted average intervals >30ppm U308 in all holes, as well as hole location data can be viewed here: https://www.blueskyuranium.com/assets/news/2017-09-18-nrt-bsk-g97x6f.pdf . The majority of holes are vertical and, as such, reported mineralized intercepts are believed to approximate true thickness.
The first 98 holes from Ivana were previously reported in the Company’s news release dated June 19th, 2017. Based on the first set of results, a follow-up program was designed, including additional electrical tomography (ET) geophysical surveying and 60 RC drill holes totaling 858 metres, to further define an area with elevated uranium-vanadium on the eastern flank of the previously-drilled area. Overall, approximately two-thirds (104) of the 158 holes at Ivana returned intervals of at least one metre of more than 30 ppm U3O8 and grades ranged as high as 3,136 ppm over 1 metre. The mineralized area now covers approximately 3,400 metres x 1,300 metres with depths to 23 metres, including higher-grade zones.

Along Line 9 between holes AGI-053 and AGI-102 the continuous mineralized corridor extends over approximately 2 kilometres with mineralized thicknesses ranging between 3 and 20 metres. Along the line of holes which parallels Line 9, 200 metres to the northwest, the strongly mineralized corridor has been defined between holes AGI-058 and AGI-133. These holes extend over approximately 1.5 kilometres, with mineralized intervals ranging in thickness from 3 to 12 metres. The mineralized corridor remains largely open to extension to the southeast and potentially connects with the >1000 grade x thickness area defined by holes AGI-124 & 137 on the eastern flank of the currently drilled area (southeastern extension on Map 1), also is open to expansion. The mineralized corridor is potentially also open to expansion to the north, from holes AGI-156 to AGI-138. The mineralization along this trend of holes is more variable and includes intervals of 7 metres of 255 ppm U3O8 and 171 V2O5 (AGI-138) including a single interval of one metre of 816 U3O8 and 205 V2O5. Drill hole highlights from the follow-up Phase I drilling at Ivana are provided below in Table 1.

The follow-up program provided new information that has resulted in the geological team updating the deposit model reflecting characteristics of sandstone-type and surficial-type uranium-vanadium mineralization. Higher-grade mineralization is believed to be related to fluvial medium-to-coarse sandstones and conglomerates within an ancient deltaic braided stream environment that lies unconformably over granitic basement. Uranium-vanadium mineralization at Ivana occurs primarily in the form of carnotite, a uranium vanadate, however in some of the higher-grade areas potentially primary mineralization was observed. Additional geophysical surveys and RC drilling to define the expansion potential of mineralized corridors is ongoing at Ivana and metallurgical testwork is also progressing on material from Ivana.
Drilling at Anit included 83 holes for a total of 1170 metres, with the deepest holes drilled to 20 metres. A map of the drill holes can be found at: https://www.blueskyuranium.com/assets/news/2017-09-18-nrm4-bsk-g97x6f.pdf . The program was designed to audit previous exploration results as well as test adjacent areas for extensions to mineralization. The program successfully confirmed the spatial correlation of the previously recognized mineralized zones. Out of 83 holes drilled, 53 returned intervals with at least one metre of more than 30 ppm U3O8. This area is particularly well-mineralized in vanadium with 55 of the holes returning intervals of at least one metre of 500 ppm V2O5, with values reaching as high as 3,411 ppm (0.34% in AGA-049). Drill hole highlights are provided below in Table 2:

Integrating the results of the 2017 RC drilling with the previous pit sampling, trench sampling and aircore drilling data is ongoing and is aimed at refining future infill and step-out drilling plans.
Santa Barbara Target
This was the first drill program at this target area and was considered a scouting program. Fifteen holes were drilled ranging from 4 to 25 metres length, for a total of 312 metres. Values of uranium and vanadium were low in all holes; this target area represents the lowest priority for follow-up work. A map of the drill holes can be found at: https://www.blueskyuranium.com/assets/news/2017-09-18-nrm5-bsk-g97x6f.pdf .
Methodology and QA/QC
Preparation of all samples reported herein was completed Bureau Veritas Minerals of Mendoza, Argentina. Samples were prepared by drying, crushing to 80% passing 10 mesh and then pulverizing a 250 g split to 95% passing 150 mesh. Pulps were analyzed by Bureau Veritas Commodities Canada Ltd. for 45 elements by means of Inductively Coupled Plasma Mass Spectrometry following a four-acid digestion (MA-200). Approximately every 10th sample a blank, duplicate, or standard sample was inserted into the sample sequence for quality assurance/quality control (QA/QC) purposes. No significant QA/QC issues were identified during review of the data.
The drilling program been carried out using an FlexiROC D65 drill rig from Atlas Copco, an ore-control track-mounted rig adapted to reverse circulation with triple cyclone to reduce the dust loss during sampling and automatic sampling. Every hole was surveyed by a senior geophysicist from Geopehuen SRL Service Company using a natural gamma probe from Geovista Ltd. The probe was previously calibrated at the Comisión Nacional de Energía Atómica facility (Atomic Energy National Commission, CNEA).
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. 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.
