"Blue Sky" or the "Company") is pleased to provide an update on current exploration and planned follow-up programs for the Company's wholly-owned Amarillo Grande Uranium-Vanadium Project in Rio Negro, Argentina ("AGP"). The AGP covers a 145 km prospective trend, including the Ivana deposit which demonstrated strong economic potential in a recent NI 43101 Preliminary Economic Assessment.

Work to date has identified three high-priority target areas with significant anomalies of uranium and vanadium. The exploration program for the next six months, including RC drilling, is designed to systematically identify and delineate mineralization potentially extending the Ivana deposit to the west (Ivana West target). The program will also test targets in two other key areas, Ivana Central and Ivana North, within 25 kilometres of the deposit.

The program includes:

Auger drilling and down-hole radiometric measurements (currently in progress)

6km-long Induced Polarization ("IP") geophysical survey (planned)

Up to 4,500 metres of reverse circulation ("RC") drilling (planned)

"Following on the heels of our successful PEA for the Ivana deposit, we are continuing exploration with confidence in the potential for discovery of additional deposits that will build value," stated Nikolaos Cacos, Blue Sky President & CEO. "Our team has made considerable advancements in exploration targeting and all of our results to date confirm significant uranium and vanadium anomalies to the west and north of the Ivana deposit, with additional prospects along the 145km-long exploration trend covered by the Amarillo Grande Project."

Program Details

On February 27th, 2019 the Company announced a PEA for the Ivana deposit, including an updated inferred mineral resource estimate of 22.7 million pounds of U308 and 11.5 million pounds of V2O5 (23.9 million tonnes averaging 0.037% U3O8 & 0.019% V2O5 at a 100 ppm uranium cut-off). The PEA concludes that the current mineral resources support 13 years of uranium and vanadium production from a surficial mining operation, with robust economics after modest capital outlay, but noted that there was still considerable potential to identify new resources to the west and north. The Company is therefore continuing exploration with a particular focus on shallow "blind" targets not exposed at surface.

Target Development

Pit sampling work completed to date, as well as past wide-spaced diamond drilling and ground radiometrics, has aided in the identification of shallow mineralized targets in the Ivana West, Ivana Central and Ivana North areas. Results from Ivana West, adjacent to the main deposit area, returned high grades of uranium and vanadium from pit sampling as reported in the Company's news releases dated November 15, 2018 and April 29, 2019. Pit sampling at the Ivana Central and North areas was completed as part of a 2011 exploration program which also returned high values of uranium (report by C.G. Verley, filed on www.sedar.com dated May 29th, 2012).

In 2013, Blue Sky's joint venture partner at the time, Areva S.A., drilled 11 core holes in the Ivana Central and North target areas totaling 2023.5 metres with depths ranging from 110 to 280 metres. Since the middle of 2018, Blue Sky's exploration team has been relogging, resampling and re-interpreting those holes and applying the in-house geological and exploration models that have been developed and refined as the Ivana deposit has been advanced. This work has identified two suites of pathfinder elements that the Company plans to employ as geochemical indicators to vector towards blind uranium deposits during the upcoming exploration program.
