Toronto, April 14, 2026 - Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) ("Purepoint") reports that the nine holes of its winter 2026 drill program at the Nova Discovery have been successful in extending the uranium mineralization and favourable geology at the Dorado Joint Venture Project ("Dorado" or the "Project"), located in Saskatchewan's Athabasca Basin. Purepoint, as operator of the 50/50 joint venture with IsoEnergy Ltd. (NYSE American: ISOU | TSX: ISO), completed 5,210 metres of drilling within the Nova Zone. Downhole probe readings peaked at 73,100 counts per second (CPS), building on previously confirmed assay grades of up to 8.1% U₃O₈ at the Nova Discovery (see September 18, 2025 NR). Regional drilling at Dorado is planned to resume in late June 2026.

"When evaluating the scale potential of a new discovery, tracking radioactivity across a one kilometre trend anchored by confirmed grades of up to 8.1% U₃O₈ is exactly what you want to see," said Chris Frostad, President and CEO. "We now have the geological framework and confidence to drill more aggressively when we return. We are disciplined in how we've approach this target and the results are showing it. The mineralization remains open."

Highlights

• The nine holes of the winter 2026 drill program expanded uranium mineralization at the Nova Discovery, extended the associated geologic contact for a strike length of one kilometre and established a refined targeting framework for continued expansion.

• Six holes intersected uranium mineralization as measured by a Mt. Sopris 2PGA-1000 downhole radiometric probe. Standout intersections include:

  • NV26-05:17,700 CPS average over 1.8 metres including 61,100 CPS average over 0.3 metres, and

  • NV26-03A: 10,600 CPS average over 1.7 metres including 41,200 CPS average over 0.3 metres

  • Program peak: 73,100 CPS.

  • The Nova Discovery remains open along strike, at the unconformity and at depth

• Winter 2026 results build on previously reported assay grades of up to 8.1% U₃O₈ at the Nova Discovery. Assays from the winter 2026 program are pending.

• Regional drilling is planned to resume at the Dorado JV Project in late June 2026.

• Airborne MobileMT survey to be conducted over Dorado this spring with interpretation to assist summer drill targeting.

Downhole Gamma Results of Winter 2026 Drill Program

Winter 2026 Drilling

NV26-01 was designed as a 50-metre step-out from PG25-07A to test mineralization at the same elevation. The hole encountered the unconformity at 317 metres followed by paleoweathered granite to granitic gneiss and a 67-metre-wide interval of unaltered pyritic graphitic pelitic gneiss with localized shearing. Anomalous radioactivity attributed to uranium was intersected between 462 and 470 metres, returning a downhole gamma peak of 3,500 CPS.

NV26-02 was drilled from the same pad as NV26-01 and designed to test mineralization 40 metres below PG25-07A. The hole encountered the unconformity at 310 metres followed by paleoweathered granite to granitic gneiss, then a chloritized brecciated pelitic gneiss with localized silicification. Anomalous radioactivity attributed to uranium was intersected between 423 and 425 metres, returning a downhole gamma peak of 18,900 CPS.

NV26-03A was designed as a 30-metre step-out from PG25-07A to follow up mineralization intersected in that hole. The unconformity was encountered at 311 metres followed by paleoweathered granite to granitic gneiss, a chloritized brecciated granite and chloritized graphitic pelitic gneiss. A 12-metre-wide zone of pelitic gneiss, hosting chloritized intervals with elevated radioactivity attributed to uranium, returned a downhole gamma peak of 55,100 CPS.

NV26-04 was designed as a 100-metre step-out to the northeast to test the granite-pelite contact. The unconformity was encountered at 318 metres followed by paleoweathered granite to granitic gneiss, then a sequence of chloritized pyritic graphitic pelitic gneiss. The strongest radioactivity was intersected at 474 metres returning a downhole gamma peak of 2,400 CPS.

NV26-05 was designed as a 65-metre step-out to the southeast to follow up PG25-07A mineralization. The unconformity was encountered at 322 metres followed by paleoweathered granitic gneiss to 390 metres, where a strongly hematized and chloritized pegmatite returned an average of 7,700 cps over 1.8 metres. The hole returned a downhole gamma peak of 73,100 CPS, the strongest result of the winter program.

NV26-06A was designed as a 260-metre step-out to the northeast to test the extent of the Nova Discovery along strike. Strong alteration was encountered in the sandstone before reaching the unconformity at 304 metres suggesting follow-up drilling for unconformity related uranium mineralization. Basement rocks were paleoweathered granite to granitic gneiss, followed by intervals of chloritized pegmatite and unaltered pyritic graphitic pelitic gneiss. Weak radioactivity was intersected with a peak of 890 cps defines the current northeastern extent of the Nova Discovery drilling.

NV26-07 was designed as a 200-metre step-out to the southwest of NV26-06A to test the granite-pelite contact along strike. The unconformity was intersected at 308 metres followed by 63 metres of paleoweathered granite, then unaltered pelitic gneisses hosting a 12-metre-wide chloritized pyritic graphitic pelitic gneiss between 385 and 397 metres. Anomalous radioactivity was returned between 334 and 338 metres within an interval of localized brittle to broken core consistent with the broader Nova Zone structural setting.

NV26-08 was designed as a 50-metre step-out to the southwest of NV26-05 to follow up the strong mineralization encountered in that hole. The unconformity was intersected at 322 metres followed by paleoweathered granite to granitic gneiss to 390 metres, then intervals of chloritized pyritic pelitic gneiss with localized graphite and an unaltered graphitic pyritic pelitic gneiss with localized brittle to broken core between 460 and 478 metres. Anomalous radioactivity was returned between 385 and 394 metres , confirming the continuity of the Nova Zone structural corridor to the southwest.

NV26-09A was designed as a 55-metre downdip step-out between NV26-08 and NV26-05 to further define the Nova Zone mineralized structure. The unconformity was intersected at 308 metres followed by paleoweathered granite to 316 metres, then unaltered granitic gneisses, granites and pegmatites to 441 metres before encountering a silicified pelitic gneiss and brecciated chloritized granite. Anomalous radioactivity was returned within the deeper graphitic and pyritic pelitic gneiss units between 470 and 557 metres, providing important structural context for the southern extent of the Nova Discovery.

About the Dorado Project
The Dorado Project is the flagship asset of the Purepoint and IsoEnergy 50/50 joint venture, encompassing more than 98,000 hectares of highly prospective uranium exploration ground in the eastern Athabasca Basin. The Project sits within one of the most prolific uranium districts on earth, surrounded by world-class deposits including IsoEnergy's Hurricane - the world's highest-grade indicated uranium resource. Underlain by the same fertile graphitic lithologies and fault structures that control high-grade uranium mineralization across the eastern Basin, Dorado hosts multiple untested conductors beyond the Nova Discovery, each representing a significant exploration opportunity. Shallow unconformity depths across the property allow for efficient drilling and rapid follow-up, positioning Purepoint to move quickly as the Nova Discovery continues to grow.
