Uraniumx Reports Anomalous Radioactivity in 300-metre
Step-out Holes at Murphy Lake
Four Holes Drilled, Four Conductor Intersections: Uranium Indicators In Every Hole
VANCOUVER, BC / ACCESS Newswire / June 9, 2026 / UraniumX Discovery Corp. (CSE: STMN)(OTCQB: STMXF)
(FSE: Q7S) ("UraniumX" or the "Company") is pleased to report additional drill results from the 2026 diamond drill program
at the Murphy Lake Uranium Property (the "Property") in the Athabasca Basin, Saskatchewan. Drill holes ML26-017 and
ML26-018, the third and fourth holes of the program, both intersected anomalous radioactivity within a thick graphitic and
sulphide-bearing deformation zone in the basement, located approximately 300 metres along strike from the holes previously
reported on June 2, 2026.
Highlights
Drill hole ML26-017 returned anomalous handheld spectrometer readings up to 460 cps within a 0.5 metre interval (386.0
to 386.5 metres), with downhole gamma probe readings peaking at 2,217 cps, and intersected a 13.2-metre graphitic and
sulphide-rich deformation zone (401.6 to 414.8 metres).
Drill hole ML26-018, drilled up-dip of ML26-017, returned anomalous handheld spectrometer readings up to 350 cps
within a 0.5 metre interval (347.0 to 347.5 metres), with downhole gamma probe readings greater than 500 cps over 6.6
metres (peak 1,097.5 cps), and intersected a 10.3-metre deformation zone (355.8 to 366.1 metres).
Combined with the visually identified pitchblende reported in drill hole ML26-015 on June 2, 2026, the first four holes
have demonstrated three consistent indicators of an active uranium mineralizing system across an approximately 300-metre
conductive corridor: graphitic and sulphide-bearing shear in the basement, intense bleaching, clay, chlorite, and limonite
alteration in sandstone and basement, and anomalous handheld and downhole gamma readings in every hole drilled. This
corridor is referred to herein as the Murphy Lake North Trend.
Four holes completed, zero barren holes. Every drill hole has returned structural, alteration, and radiometric indicators on
targets identified by the Company-funded MLEM survey. No drill hole completed to date has been abandoned, and no drill
hole has been returned barren of indicator response.
The program is now advancing to Target Area 4 to test along strike from historical drill hole ML22-006, which intersected
0.242% U3O8 over 0.5 metres within a graphitic deformation zone. Assay results from drill holes ML26-015 through
ML26-018 are pending.
Drill Program Results
Drill holes ML26-017 and ML26-018 were drilled at Target Area 2 on the Property (see Figure 1), testing a conductor target
along strike of the same resistivity low trend as Target Area 1, as identified by the Company-funded MLEM survey (see news
release dated May 5, 2026).
Drill hole ML26-017 returned handheld spectrometer readings greater than 300 cps over 0.5 metres at 386.0 to 386.5 metres
(peak 460 cps), with corresponding downhole gamma probe readings greater than 500 cps over 0.4 metres (peak 2,217 cps).
ML26-017 intersected a 13.2-metre graphitic and sulphide-rich deformation zone from 401.6 to 414.8 metres. Both holes
encountered the same style of conductive structure imaged by the Company-funded MLEM survey.
Drill hole ML26-018, drilled up-dip of ML26-017, returned handheld spectrometer readings greater than 300 cps over 0.5 metres
at 347.0 to 347.5 metres (peak 350 cps), with corresponding downhole gamma probe readings greater than 500 cps over 6.6
metres (peak 1,097.5 cps). ML26-018 intersected a 10.3-metre deformation zone from 355.8 to 366.1 metres

The First Four Holes Have Answered Key Questions.
With four drill holes completed in the 2026 Phase 1 program, the following has been demonstrated across the Murphy Lake
North Trend, an approximately 300-metre conductive corridor at the northern end of the Property:
The conductive structure imaged by the May 2026 MLEM survey has been confirmed by drilling and is present at every
drilled target across approximately 300 metres of strike;
A consistent graphitic and sulphide-bearing shear zone is present in the basement at each tested location;
Intense hydrothermal alteration, including strong bleaching, clay, chlorite, and patchy limonite alteration, is present in both
the sandstone above the unconformity and the basement at each tested location;
Uranium-bearing fluids reached the Property, as evidenced by the visually identified pitchblende reported in drill hole
ML26-015 above the unconformity (see news release dated June 2, 2026); and
Handheld spectrometer and downhole gamma probe readings exceeded the Company's designated "anomalous" thresholds
in every drill hole completed to date.
Taken together, these results establish the geological context of an active uranium mineralizing system. The Murphy Lake North
Trend has been drill-confirmed across approximately 300 metres of strike with consistent geological signature in each hole.
Laboratory assay results from drill holes ML26-015 through ML26-018 are anticipated in the second half of 2026 and will
determine the uranium content of the intercepts described in this news release and in the news release dated June 2, 2026.
The remaining objective of the 2026 exploration program is to determine whether high-grade uranium mineralization is present
within the now-confirmed conductive corridor. The Company's view, supported by the targeting model defined by the MLEM
survey and the geological response across the first four drill holes, is that systematic follow-up drilling across the Murphy Lake
North Trend and the remaining MLEM-defined priority target areas represents the highest-impact path to making that
determination. Such follow-up drilling would be subject to capital availability and continued positive geological results.
What Comes Next
The program will now advance to Target Area 4, located at the southern end of the Murphy Lake Property and along strike from
F4's 2022 historical drill hole ML22-006, which intersected 0.065% U3O8 over 2.5 metres, including 0.242% U3O8 over 0.5
metres (see Murphy Lake NI 43-101 Technical Report on SEDAR+). Target Area 4 was identified and refined by the May 2026
MLEM survey.
Beyond the currently funded Phase 1 program, the Company is evaluating options to expand the 2026 exploration program to
include systematic follow-up across the Murphy Lake North Trend and the remaining MLEM-defined priority target areas. Any
such expansion would be subject to capital availability and continued positive geological results.
Murphy Lake sits in the heart of the eastern Athabasca Basin's most active exploration corridor, 5 km from IsoEnergy's Hurricane
Deposit, the world's highest-grade indicated uranium resource (IsoEnergy Ltd. news release dated July 18, 2022), and 4 km from
Cameco's La Rocque Lake Uranium Zone, where drill hole Q22-040 intersected 29.9% U3O8 over 7.0 metres (Cameco
Corporation 2023 Annual Information Form, dated March 22, 2024).
Esen Boldkhuu, Chief Executive Officer of UraniumX, commented: "Pitchblende in Hole 1, the same conductor and alteration
package 300 metres along strike in Holes 3 and 4, all within 5 km of IsoEnergy's Hurricane deposit. The MLEM survey worked,
the corridor is proven, and the next phase of drilling will test along strike of F4's 2022 intercept of 0.242% U3O8."
