IsoEnergy and Purepoint Confirm Uranium Discovery in Initial Drilling at the Dorado Joint Venture Project

[{"type":"text","content":"IsoEnergy and Purepoint Confirm Uranium Discovery in Initial Drilling at the Dorado Joint Venture ProjectToronto, Ontario--(Newsfile Corp. - July 8, 2025) - IsoEnergy Ltd. (NYSE American: ISOU) (TSX: ISO) (\"IsoEnergy\") and Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) (\"Purepoint\") are pleased to announce a highly encouraging start to the inaugural drill program at their 50/50 Dorado project (\"Dorado\" or the \"Project\"), located in Saskatchewan's world-class Athabasca Basin (Figure 1). Initial drilling at the Q48 target on the Project, completed by Purepoint as the operator of the program, intersected uranium mineralization in two holes, with downhole gamma probe readings up to 79,800 counts per second (CPS). The intercepts occur within strongly altered basement rocks – suggesting an active uranium-bearing hydrothermal system. HighlightsInitial drillholes at the Q48 target, located in the southern portion of the Project, have intersected uranium mineralization, confirming the zone as a significant uranium-bearing structure. (Figure 2).Drillholes PG25-04 and PG25-05 intersected a steeply dipping, north-south trending mineralized structure at vertical depths of 60 and 20 metres below the unconformity, respectively.Radioactivity readings from downhole probe measurements averaged 11,050 cps over 3.7 metres with a maximum of 74,800 in PG25-04, and 27,750 over 2.3 metres with a maximum of 79,800 in PG25-05 (See Table 1 for full details).Mineralization is hosted within strongly clay-altered basement rocks—considered key indicators of a uranium-bearing hydrothermal system consistent with known Athabasca-style deposits.Q48 was originally highlighted as a high-priority target based on historic drilling that encountered structurally disrupted, altered basement rocks with weak radioactivity, and further confirmed in 2022 by IsoEnergy's identification of brittle faults, shearing, and alteration along the conductive trend.A third follow-up hole is underway to further track the mineralized structure along the Q48 conductive corridor to the northeast. Approximately 5,400 metres in 18 drill holes are planned for the Project in 2025. \"This is exactly the kind of start we were aiming for. These early results suggest we're on the trail of something meaningful,\" said Chris Frostad, President and CEO at Purepoint...
