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 electromagnetic ("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.
