ALX Uranium Corp. Uranium Exploration Update, Athabasca Basin, Saskatchewan

Vancouver, September 6, 2018 - ALX Uranium Corp. (TSXV: AL) (FSE: 6LLN) (OTC: ALXEF) ("ALX" or the "Company") is pleased to report geochemical results from its inaugural diamond drilling program at the Newnham Lake Uranium Project ("Newnham Lake") and ground geophysical results from the Perch Project ("Perch"), each located in the northeastern Athabasca Basin of northern Saskatchewan, east of Stony Rapids.

Newnham Lake 2018 Drilling Program

The 2018 drilling program at Newnham Lake consisted of three drill holes totaling approximately 1,164 metres. The three drill holes were designed to test high-priority drill targets interpreted from integrating the results of a historical airborne ZTEM™ survey with a 3D induced polarization/resistivity ("IP/resistivity") ground geophysical survey carried out by ALX in 2017, along with other historical data.

Highlights of the 2018 Drilling Program

• Drill hole NL18-001 was drilled to test a target approximately 140 metres along strike to the east of historical drill hole BL-066, drilled in 1979. Hole BL-066 intersected 1,656 parts per million ("ppm") uranium over 0.20 metres from 86.9 to 87.1 metres in basement pelitic gneiss just below the base of the Athabasca sandstone. Drill hole NL18-001 intersected approximately 6.0 metres of elevated radioactivity (see ALX news release dated May 14, 2018) straddling the sub-Athabasca unconformity, which included visible pitchblende. A 5.7 metre interval averaged 0.035% U₃O₈ from 100.8 to 106.5 metres, including a sample containing 0.118% U₃O₈ over 0.5 metres. Uranium pathfinder elements returned from the interval include nickel (up to 149 ppm Ni), arsenic (up to 64 ppm As) and boron (up to 217 ppm B);

• Drill hole NL18-002 was drilled approximately 200 metres along strike to the southeast of historical drill hole BL-090, drilled in 1980. Hole BL090 intersected 855 ppm uranium over 0.3 metres from 74.2 to 75.5 metres in locally graphitic pelitic gneiss 10 metres below the unconformity. Drill hole NL18-002 encountered a fault zone just above the unconformity consisting of highly brecciated, broken and rubbly core with elevated radioactivity. A strongly hematized red zone in the basement rocks just below the fault zone also shows elevated radioactivity. Geochemical sampling of the fault zone and upper portion of the red zone returned anomalous uranium (up to 202 ppm U), nickel (up to 74 ppm Ni) and boron (up to 207 ppm);

• Drill hole NL18-003 was drilled approximately 200 metres along strike to the northwest of historical drill hole BL-146, drilled in 1983. Drill hole BL146 intersected 2,260 ppm uranium over 0.13 metres straddling the unconformity from 83.64 to 83.77 metres. Drill hole NL18-003 intersected a large fault zone deep in the basement rocks approximately 62 metres wide with brecciation, fracturing and evidence of strong hydrothermal alteration. Geochemical sampling of the fault zone returned elevated uranium (up to 94 ppm U), nickel (up to 126 ppm Ni), cobalt (up to 361 ppm Co), vanadium (up to 136 ppm V) and boron (up to 362 ppm B).

"The presence of uranium mineralization over significant widths as well as intense faulting and strong hydrothermal alteration deep in the basement represent key elements of the basement-hosted uranium model," said Sierd Eriks, President and Chief Geologist of ALX. "Our initial drilling results demonstrate that Newnham Lake shows the hallmarks of a fertile mineralizing environment for uranium."

Perch 2018 Geophysical Program

A ground electromagnetic geophysical survey was carried out by ALX during the winter of 2018 to further explore anomalies identified during a 2016 gravity survey with the goal of defining drill targets. A total of 22.7 line-km were surveyed using a PROMIS Horizontal Loop Electromagnetic (HLEM) system. The interpreted HLEM conductors compare reasonably to the results of an airborne VTEM survey carried out in 2007. An interpreted cross structure from inversions of the HLEM data confirmed previously-identified structural magnetic features. In addition, a conductive bright spot and other interpreted cross structures occur over a gravity high anomaly seen in the 2016 gravity survey, indicating that the anomaly may be due to possible silicification, an important form of sandstone alteration related to hydrothermal processes.
