Purepoint Intersects 7.4 Metres Averaging
8,760 CPS at the Unconformity in First Drill
Hole at Q24, Dorado Project
Toronto, Ontario--(Newsfile Corp. - September 17, 2026) -
Purepoint Uranium Group Inc. (TSXV:
PTU) (OTCQB: PTUUF) ("Purepoint")
today reported radiometric results from the completed 2026
summer drill program at the 50/50 Dorado Joint Venture ("Dorado" or the "Project") with IsoEnergy Ltd.
(NYSE American: ISOU) (TSX: ISO), located in Saskatchewan's Athabasca Basin. Drill hole PG26-11,
the first hole completed at the Q24 target, intersected 7.4 metres averaging 8,760 counts per second
("cps") across the unconformity, including 0.5 metres averaging 38,710 cps. The Q24 radioactive
interval occurs primarily within strongly altered and structurally disrupted basement rocks, at a separate
target area from both Nova and Q23.
"The first hole at Q24 delivered exactly what we look for in this part of the Athabasca Basin; strong
radioactivity at the unconformity, significant alteration, structural disruption and graphitic basement
rocks," said Chris Frostad, President & CEO of Purepoint. "These geological features have guided
uranium exploration in this district for decades and seeing them come together in the first hole at a new
target area is really encouraging. Q24 is separate from both Nova and Q23, giving us an important new
area for follow-up drilling at Dorado."
Highlights
PG26-11, the first hole drilled at Q24, intersected 7.4 metres averaging 8,760 cps from 284.1 to
291.5 metres at the unconformity, including 0.5 metres averaging 38,710 cps. The maximum
downhole probe reading is 50,110 cps.
The radioactive interval occurs within strongly clay-sericite-chlorite altered basement rocks (pelitic
gneiss) having local fault brecciation. Chalcopyrite veining was observed 3.3 metres farther
downhole, providing additional evidence of hydrothermal activity.
Q24 is a separate target from Nova and Q23, adding another priority area for follow-up drilling at
Dorado.
At the Q23 target, hole PG26-10 intersected intervals of elevated radioactivity associated with
altered sandstone and basement rocks.
Q24 Target — First-Pass Drilling
PG26-11, the first drill hole completed at Q24, tested a strong ground electromagnetic (EM) conductor
(Figures 1 and 2) and encountered strongly altered and broken sandstone before reaching the
unconformity at approximately 285 metres. The principal radioactive interval extended from 284.1 to
291.5 metres and averaged 8,760 cps over 7.4 metres, including 0.5 metres averaging 38,710 cps.
Core recovery was incomplete within this higher-radioactivity interval; assays from the recoverable
portion are pending. Chalcopyrite (copper-bearing) veining was observed 3.3 metres farther downhole
at 294.8 metres (Figure 3).
The hole encountered sericite, clay and chlorite altered pelitic gneiss from the unconformity to a depth of
318 metres. A second radioactive interval, just below the chalcopyrite veining, averaged 1,010 cps over
6.2 metres from 297.2 to 303.4 metres. Pyritic graphitic pelitic gneiss, with chlorite alteration and local
fault breccia, was drilled from 318 to 343 metres then unaltered pelitic gneiss to a final depth of 551
metres.
Additional Results from Q23 Target
Summer drilling also tested the Q23 target area located east of Q24. PG26-10 returned several intervals
of elevated radioactivity, including 0.8 metres averaging 1,000 cps from 292.0 to 292.8 metres, 1.2
metres averaging 1,030 cps from 339.5 to 340.7 metres and 1.7 metres averaging 660 cps from 349.4
to 350.8 metres.
The hole also encountered significant desilicification and broken core in the lower sandstone, together
with altered basement rocks. The Q23 results provide an additional priority target area for evaluation as
the Joint Venture integrates the summer program into its 2027 exploration priorities.
2026 Summer Program
The 2026 summer drill program completed 3,669 metres of drilling across the Nova, Q23 and Q24
target areas. The program tested multiple geological and geophysical settings across Dorado, with
radioactivity encountered at more than one target, reinforcing the Joint Venture's strategy of
systematically evaluating multiple prospective corridors across the Project. The first-pass Q24 result,
together with the Q23 results and the broader geological information collected during the program, will
be integrated with the final MobileMT structural interpretations to establish priorities for the 2027
exploration program.
Demobilization was completed in September. Laboratory assays from the summer drilling remain
pending and will be reported when they become available, together with their incorporation into the Joint
Venture's 2027 exploration planning.

About the Dorado Project
The Dorado Project is located along the eastern margin of Saskatchewan's Athabasca Basin in
Canada. The property covers prospective structural corridors considered favourable for unconformity-
related uranium mineralization and is operated by Purepoint under a 50/50 joint venture with IsoEnergy
Ltd.
Dorado hosts the Nova Discovery, where previous drilling returned assays of up to 8.1% U3O8 over 0.4
metres within 1.62% U3O8 over 2.1 metres. Uranium mineralization has been identified along a
prospective structural corridor extending approximately one kilometre and is associated with intense
alteration, structural disruption and graphitic basement rocks.
Exploration at Dorado is focused on advancing the Nova Discovery while systematically evaluating
additional priority targets across the Project's prospective structural and conductive corridors, including
Q23 and Q24.
Gamma Logging
A Mount Sopris 2PGA-1000 downhole total gamma probe was utilized for radiometric surveying and
counts per second reported in this press release.
A handheld RS-125 Gamma-Ray Spectrometer is used during core sampling and provides a readout of
equivalent % K, ppm of U and Th. All drill intercepts are core width, and true thickness is yet to be
determined.
