Star Metro - UraniumX Commences Drill Program at Murphy Lake

VANCOUVER, BC / ACCESS Newswire / May 26, 2026 / UraniumX Discovery Corp. (CSE:STMN)(OTCQB:STMXF)(FSE:Q7S) ("UraniumX" or the "Company") is pleased to announce the commencement of diamond drilling at its flagship Murphy Lake Property (the "Property") in the Athabasca Basin, Saskatchewan - the world's premier uranium jurisdiction. Operator F4 Uranium Corp. (TSXV: FFU) ("F4") is directing the program. The program is fully funded with ~$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% U₃O₈ over 2.5 metres, including 0.242% U₃O₈ over 0.5 metres, 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 ppm 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 underway will test the target areas.

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

• 5 km - IsoEnergy's Hurricane Deposit: just reported 11.61% U₃O₈ over 1.0 m (4.21% 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 news release dated May 12, 2026).

• 4 km south - Cosa Resources' Murphy Lake North Project: hole MLN26-013 cut 5.0 metres of anomalous radioactivity peaking at 13,900 cps on the Cyclone structural trend - the same basement architecture that runs through Murphy Lake. (Cosa news release dated March 24, 2026).

• 4 km east - Cameco's La Rocque Lake Uranium Zone: 29.9% U₃O₈ over 7.0 metres (Cameco Corporation 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 km 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 (see Figure 1).

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 km northwest of Orano's McClean Lake deposits, 5 km south of IsoEnergy Ltd.'s (TSX: ISO) Hurricane Deposit, 4 km from the Cosa Resources (TSXV: COSA) Cyclone structural trend, and 4 km east of Cameco Corporation's (TSX: CCO) La Rocque Lake Uranium Zone. F4's 2022 maiden drill program at the Property comprised 14 drill holes totaling 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.
