ALX Uranium Corp.

Vancouver, British Columbia--(Newsfile Corp. - August 21, 2019) - ALX Uranium Corp. (TSXV: AL) (FSE: 6LLN) (OTC: ALXEF) ("ALX" or the "Company") announced today that a three-year extension of time (the "Agreement") has been granted by a vendor to ALX for two claims totaling 1,518.6 hectares (the "Claims") within its 100%-owned Newnham Lake Uranium Project ("Newnham Lake", or the "Project") located in the northeastern Athabasca Basin of northern Saskatchewan, approximately 75 kilometres east of Stony Rapids.

Under the terms of an option agreement dated August 21, 2014, ALX was obligated to spend $1.5 million in exploration expenditures on the Claims by August 28, 2019. All other monetary terms of the option agreement (cash and shares payable to the vendor) have been satisfied by ALX. In consideration for a three-year extension to August 28, 2022 for ALX to complete the exploration expenditures, ALX has agreed to issue to the vendor 300,000 common shares of the Company.

This Agreement is subject to acceptance by the TSX Venture Exchange.

About Newnham Lake

Newnham Lake consists of fifteen claims totaling 18,524 hectares (45,773 acres), where ALX has three separate option agreements to acquire a 100% interest in the Project.

Historical drilling in the 1970s and 1980s identified encouraging amounts of uranium mineralization in the vicinity of the unconformity at shallow depths. However, due to the exploration model envisaged at the time the focus was on unconformity-hosted deposits and hence most drill holes were less than 100 metres in length. For example, 1979 hole BL-066 intersected 1,656 ppm uranium over 0.20 metres in a section containing visible grains of pitchblende, a uranium mineral commonly found associated with Athabasca Basin uranium deposits. This intersection began just below the unconformity at a depth of 86.7 metres, but the hole only tested the basement rocks to a depth 26.7 metres below the unconformity and was terminated in graphitic basement rocks at a vertical depth of 113.4 metres. Similar encouraging uranium intersections by previous operators resulted in the completion of over 150 holes in the most promising areas of the property, focused almost entirely on unconformity-hosted targets. ALX believes that the potential for uranium mineralization exists "down-dip" along the conductive structures deeper in the basement rocks, which remain relatively untested, since previous explorers concentrated on the "up-dip" expression of uranium mineralization at the unconformity between the overlying sandstone and the basement rocks.
