ALX Uranium Corp. Announces Vesting of 40% Interest in Black Lake Uranium Project, Athabasca Basin

In September 2017, ALX signed a definitive agreement with UEX, whereby ALX can earn up to a 75% participating interest from UEX in Black Lake (for additional details of the earn-in terms, see ALX news release dated July 31, 2017). Black Lake is currently the subject of a joint venture, in which UEX until recently held a 90.92% interest in the Project, with Orano Canada Inc. (formerly AREVA Resources Canada Inc.) holding the remaining 9.08% interest. ALX has earned its 40% interest in the Project from UEX by meeting an initial commitment of $1.0 million in exploration expenditures and issuing 5.0 million common shares of ALX to UEX. ALX is operator of exploration at Black Lake.

Results of the 2017 Drilling Program

The 2017 fall drilling program at Black Lake consisted of five holes totaling approximately 2,830 metres designed to test new target areas developed by ALX in the northern portion of Black Lake. All five holes intersected graphitic fault zones in the basement rocks. Sandstone alteration observed included dravite veining, siderite and minor pyrite, and basement alteration included hematization, chloritization, saussuritization and carbonate veining. Geochemical results in selective samples from the sandstone show elevated uranium and lead values (up to 117 parts per million ("ppm") U and 97 ppm Pb) and anomalous values of boron (up to 1,430 ppm B).

Two of the drill holes, BL-155 and BL-156, intersected narrow intervals of uranium mineralization in the basement where pitchblende, a uranium mineral, was observed in veinlets just below the unconformity, at depths of 316.7 metres and 272.8 metres respectively. Geochemical results returned 0.06% U₃O₈ over 0.15 m in hole BL-155 and 0.03% U₃O₈ over 0.07 metres in hole BL-156 corresponding to these pitchblende veinlets. Large graphite-rich fault zones, varying from 34 to 68 metres thick with local strongly graphitic to carbonaceous breccias were intersected in holes BL-152, BL-153 and BL-156. These graphitic fault zones are enriched in uranium pathfinder elements such as nickel (up to 401 ppm Ni), copper (up to 1,420 ppm Cu), cobalt (up to 81 ppm Co) and boron (up to 195 ppm B).

An independent geological review of the Project commissioned by ALX on both historical exploration at Black Lake and ALX's 2017 exploration program concluded that highly-prospective target areas remain at the Project, and should be tested by further drilling. ALX plans to carry out additional holes on the sparsely-drilled western edge of the conductive system and on deeper targets in the central part of Black Lake.

About Black Lake

Black Lake consists of 12 claims totaling 30,381 hectares with all-weather road access and nearby infrastructure, including a commercial airport. The Project lies adjacent to ALX's Gibbons Creek project.

In 2004, UEX intersected a significant intersection of uranium mineralization in drill hole BL-18 (0.69% U₃O₈ over 4.4 metres, including 1.09% U₃O₈ over 1.5 metres) which sparked an extensive amount of exploration work in the northern Athabasca Basin by UEX and other uranium exploration companies. Several other mineralized holes were drilled at the Project over the next ten years, but despite encountering a series of uranium occurrences, no new uranium deposit was discovered.

Black Lake hosts a 24 kilometre-long conductive system and is staked over the Platt Creek Fault, a major NNE-trending fault parallel to the Black Lake Fault. Previous drilling in the northern part of Black Lake encountered uranium mineralization at the unconformity between the overlying Athabasca sandstone and underlying basement rocks at downhole depths between 274.10 metres and 340.75 metres. Historical exploration has also demonstrated the potential for a polymetallic mineralizing system in relatively shallow sandstone cover that ranges from 225 to 300 metres. A predecessor company of UEX re-sampled historical drill hole RL‑4B drilled by Eldorado Uranium in 1980, which returned values of 171.6 ppm uranium, 0.207% cobalt and 256 ppm nickel over 0.75 metres from 251.00 to 251.75 metres in basement rocks, approximately 25 metres below the unconformity.
