UraniumX and F4 Complete Murphy Lake Drilling, Define Two Mineralized Trends
UraniumX and F4 Complete Murphy Lake Drilling, Define Two Mineralized
Trends
SIX OF NINE HOLES RETURN ANOMALOUS RADIOACTIVITY IN EXPANDED 4,092 METRE
CAMPAIGN
VANCOUVER, BC / ACCESS Newswire / July 7, 2026 / UraniumX Discovery Corp. (CSE: STMN)
(OTCQB: STMXF) (FSE: Q7S) (“ UraniumX” or the “ Company”) is pleased to announce that it has
completed its expanded 2026 diamond drill program at its flagship Murphy Lake Property (the “Property”)
in the Athabasca Basin, Saskatchewan. Operator F4 Uranium Corp. (TSXV: FFU) (“F4”) directed the
program, which was fully funded by UraniumX under the existing option agreement through which the
Company is earning up to a 70% interest in the Property.
The program was expanded during execution from an originally planned approximately 2,500 metres to a
completed 4,092 metres in nine drill holes across six target areas. Drilling tested priority target areas
identified by the 2026 moving loop electromagneti c (“MLEM”) survey and defined two distinct trends: the
Murphy Lake North Trend and the Murphy Lake South Trend. Anomalous radioactivity was intersected in
five of the six target areas tested, with six of the nine holes returning elevated radioactivity and multiple
holes displaying strong hydrothermal alteration at the unconformity. Core has been logged and sampled,
and assay results are pending.
The final two holes of the program, ML26-022 and ML26-023, were completed on the Murphy Lake South
Trend at Target Areas 6 and 3 respectively, testing two modelled conductors running parallel to the
conductor that hosts mineralized hole ML22-006 (0.065% U3O8 over 2.5 metres, including 0.242% U3O8
over 0.5 metres; see F3 Uranium Corp. news release dated August 10, 2022). ML26-023 intersected
anomalous radioactivity of up to 400 cps over 0.5 metres in basement rocks just below the unconformity,
with downhole gamma readings greater than 500 cps over a total of 3.2 metres peaking at 2,696.9 cps,
the highest downhole gamma peak reported during the program. ML26-022 encountered limonite
alteration in the sandstone above the unconformity and a weakly altered shear zone in the basement,
with no radioactivity above 300 cps.
Program Highlights
• Program expanded by approximately 64%. The 2026 campaign was expanded from an
originally planned 2,500 metres to a completed 4,092 metres in nine drill holes; the consistently
encouraging results gave the partners the confidence to expand the program across the
Property’s target areas.
• Anomalous radioactivity in five of six target areas. Anomalous radioactivity was intersected
in five of the six target areas drill tested, with six of nine holes returning elevated radioactivity
across two distinct trends, the Murphy Lake North Trend (Target Areas 1 and 2) and the Murphy
Lake South Trend (Target Areas 3, 4, 5 and 6).
• Two trends defined. Drilling defined two mineralized trends on the Property: the North Trend,
where anomalous radioactivity was intersected over more than 330 metres of strike length
including visually identified pitchblende in ML26-015; and the South Trend, now extended to a
strike length of nearly 1.3 kilometres, where ML26- 019A, ML26-021 and ML26 -023 returned
anomalous radioactivity along strike from the 2022 mineralized intercept in hole ML22-006.
• Highest reported downhole response of the program. Hole ML26-023, one of the final two
holes of the program, returned the highest downhole gamma peak reported during the program
at 2,696.9 cps, with anomalous downhole readings greater than 500 cps over a total of 3.2
metres (286.1 to 287.7 metres and 290.6 to 292.2 metres) and handheld readings up to 400
cps in the first basement rocks below the unconformity (Figure 3), complementing ML26-019A's
peak of 2,564 cps (see Technical Disclosure; radiometric readings are preliminary, are not a
measure of uranium grade, and may not correlate with chemical assays).
• Assays are the next catalyst. Core has been logged and sampled; assay results from the
program are anticipated in the second half of 2026.
Results in Context
The Murphy Lake Property is situated in the northeastern Athabasca Basin, approximately 5 km south of
IsoEnergy’s Hurricane deposit and approximately 4 km from Cameco’s La Rocque Lake Uranium Zone.
The Property lies approximately 30 km northwest of Orano’s McClean Lake deposits and uranium
processing facility. The 2026 drill program represents the first systematic test of MLEM-defined conductors
on the Property and has established the presence of two mineralized trends with anomalous radioactivity
and strong hydrothermal alteration.
The North Trend was tested at Target Areas 1 and 2 and the South Trend at Target Areas 3, 4, 5 and 6;
Target Area 6 was the only area tested that did not return radioactivity above 300 cps. The consistency of
anomalous radioactivity across both trends, combined with strong hydrothermal alteration at the
unconformity in multiple holes, is considered highly encouraging by the Company’s geological team.

Ground Geophysics
UraniumX intends to fund a follow -up ground geophysical survey program, subject to planning with F4 as
operator, to refine and expand drill targets across the Property. The survey is expected to extend the
coverage of MLEM and other geophysical methods along both the North Trend and South Trend to identify
additional conductive corridors for future drilling. Results would be integrated with the 2026 drill results to
prioritize targets for the next phase of exploration.
Esen Boldkhuu, CEO of UraniumX, commented: “We set out to test both trends and we did exactly that,
significantly exceeding our initial target of 2,500 metres with 4,092 metres completed across nine drill holes.
Two distinct mineralized trends are now defined across the Property: the North Trend with anomalous
radioactivity over more than 330 metres of strike and visible pitchblende in our very first hole, and the South
Trend, now nearly 1.3 kilometres, along strike from the historical intersection in hole ML22-006. ML26-023,
one of our final two holes, returned the highest downhole gamma peak reported during the program at
2,696.9 cps. Anomalous radioactivity in five of the six target areas we tested is exactly the consistency we
wanted to establish before assays, and we look forward to reporting the laboratory results as they are
received.”
Next Steps
Assay results from the 2026 drill program are anticipated in the second half of 2026. Core samples have
been submitted to Saskatchewan Research Council’s Geoanalytical Laboratories in Saskatoon for multi -
element analysis including uranium (U3O8). UraniumX will report assay results promptly upon receipt.
The integration of drill results with new geophysical data will inform the design of the next drill program at
Murphy Lake.

Technical Disclosure
Handheld spectrometer readings reported in this news release were obtained using a handheld Radiation Solutions
RS-125 spectrometer on drill core. Downhole gamma readings were obtained from a Mount Sopris QL-40GR downhole
natural gamma probe. Radiometric r eadings are a preliminary indication of the presence of radioactive minerals and
are not a direct or reliable measure of uranium grade. Radiometric readings may not correlate with chemical assay
results. Visual identification of mineralization, including pitchblende, is preliminary in nature and is not a substitute for
chemical assay. Assay results from chemical analysis of core samples are required to determine uranium grades and
are pending. Composite parameters applied to handheld spectrometer data: mini mum composite thickness of 0.5 m,
cut off of 300 cps, and maximum internal dilution of 2.0 m. All reported intervals are downhole lengths; true thicknesses
have not been determined.
