URANIUMX COMMENCES DRILL PROGRAM AT MURPHY LAKE

UraniumX Discovery Corp. has commenced diamond drilling at its flagship Murphy Lake property in the Athabasca basin in Saskatchewan -- the world's premier uranium jurisdiction. Operator F4 Uranium Corp. is directing the program. The program is fully financed with approximately $2-million. The program represents UraniumX's most significant exploration commitment to date and targets all five priority areas identified by the company's recently completed moving-loop electromagnetic (MLEM) geophysical survey.

The 2022 maiden drill program at Murphy Lake delivered the potential proof of concept as a working uranium system. Drill hole ML22-006 intersected 0.065 per cent U3O8 (triuranium octoxide) over 2.5 metres, including 0.242 per cent U3O8 over 0.5 metre, within a 4.2-metre-wide basement deformation zone at the unconformity contact. Drill hole ML22-012, 1.4 kilometres to the north of the property, returned 56 parts per million uranium in sandstone above the unconformity. Across the property, the program confirmed the full suite of discovery indicators -- clay, hematite and limonite alteration patterns, basement-hosted graphitic shears and anomalous radioactivity.

UraniumX is building on the 2022 maiden drill program and commissioned the MLEM survey that extended and refined the conductor framework across the property by 1.45 kilometres and vectored five priority target areas (see news release dated May 5, 2026). The drill program now under way will test the target areas.

Within five kilometres of the property, neighbours have delivered some of the most significant uranium drill results:

• Five kilometres -- IsoEnergy Ltd.'s Hurricane deposit: just reported 11.61 per cent U3O8 over 1.0 m (4.21 per cent over 3.5 m) on the Hurricane South trend -- extending the world's highest-grade indicated uranium resource beyond its existing footprint; Murphy Lake sits on the same structural trend (IsoEnergy's news release dated May 12, 2026);
• Four kilometres south -- Cosa Resources' Murphy Lake North project: hole MLN26-013 cut 5.0 metres of anomalous radioactivity peaking at 13,900 counts per second on the Cyclone structural trend -- the same basement architecture that runs through Murphy Lake (Cosa's news release dated March 24, 2026);
• Four kilometres east -- Cameco Corp.'s La Rocque Lake uranium zone: 29.9 per cent U3O8 over 7.0 metres (Cameco's 2023 annual information form, dated March 22, 2024) -- world-class grades from one of the world's largest uranium producers, immediately adjacent to Murphy Lake ground; Murphy Lake is also 30 kilometres northwest of Orano's McClean Lake milling operations.

Drilling at the property will begin in Target Area 1, in the northern zone near historic hole ML22-012, where the 2022 sandstone uranium intercept points to the underlying unconformity.

Esen Boldkhuu, chief executive officer of UraniumX, commented: "The 2022 program gave us uranium mineralization and strong alteration indicators. The MLEM survey provided us with five drill-ready targets. And now our neighbours -- IsoEnergy and Cosa -- have delivered a wave of world-class results within five kilometres of our property. We believe that we are in the right place, with the right operator, at the right time."

About Murphy Lake

The 609-hectare Murphy Lake property is located in the northeastern Athabasca basin, approximately 30 kilometres northwest of Orano's McClean Lake deposits, five kilometres south of IsoEnerg's Hurricane deposit, four kilometres from Cosa Resources' Cyclone structural trend and four kilometres east of Cameco's La Rocque Lake uranium zone. F4's 2022 maiden drill program at the property comprised 14 drill holes totalling 6,850 metres and confirmed a geological setting consistent with the unconformity-hosted uranium deposit model that characterizes the major deposits in the eastern Athabasca basin.

For additional information on the Murphy Lake property, please refer to the National Instrument 43-101 report titled "Technical Report For The Murphy Lake Project, NE Athabasca Basin, Saskatchewan, Canada," effective March 20, 2024, available on SEDAR+.

Mineralization on those neighboring properties is not necessarily indicative of mineralization on the Murphy Lake property.

About UraniumX Discovery Corp.

UraniumX is a Canadian-based junior uranium exploration company focused on advancing uranium properties in Saskatchewan's Athabasca basin, one of Canada's most active uranium districts. The company's flagship Murphy Lake uranium property is located in the northeastern Athabasca basin, where UraniumX is earning up to a 70-per-cent interest through an option agreement with F4 Uranium. UraniumX additionally holds 100-per-cent interests in the Zoo Bay and NeoCore uranium properties and is advancing a project generator approach across its broader portfolio by optioning non-core assets while retaining royalties and equity, allowing the company to concentrate exploration capital on Murphy Lake.
