Standard Uranium begins first drilling at Rocas project in Athabasca Basin

Standard Uranium Vice President of Exploration Sean Hillacre joined Steve Darling from Proactive to announce that drilling has officially commenced at the Company’s Rocas Uranium Project, located approximately 75 kilometres southwest of the Key Lake Mine and Mill facilities. The Rocas Project is subject to a three-year earn-in option agreement with Collective Metals, which can earn a 75% interest by funding CAD$4.5 million in exploration expenditures. Under the agreement, the current drill program is fully funded by Collective Metals and operated by Standard Uranium. The exploration team mobilized to site on March 16, with diamond drilling now underway on the first-ever hole at Rocas. The winter/spring 2026 campaign is expected to comprise approximately 1,200 to 1,500 metres of drilling, targeting high-priority zones identified through a 2025 ground gravity survey and integrated geophysical modeling. Rocas covers 4,002 hectares across three mineral claims along Highway 914 in the southeastern Athabasca Basin, a globally significant uranium district. Recent fieldwork has confirmed the presence of both uranium and rare earth element (REE) mineralization across the property. Notably, a newly identified pegmatite outcrop returned assays of up to 9.83% total rare earth oxides (TREO) and 0.016% U₃O₈ from grab samples. Additional uranium assays from outcrop and boulder samples across the project range from 0.007% to 0.409% U₃O₈, highlighting widespread mineralization potential. The inaugural drill program will focus on testing high-priority targets along a 7.5-kilometre magnetic low and electromagnetic conductive corridor. This corridor coincides with gravity lows, cross-cutting structural features, and multiple uranium and REE surface occurrences, making it a compelling exploration target. Management believes the program represents a key milestone in unlocking the project’s potential, as Standard Uranium advances exploration efforts within one of the world’s premier uranium jurisdictions. #proactiveinvestors #standarduraniumltd #tsxv #stnd #otcqb #sttdf #mining #uranium #SeanHillacre #RocasProject #AthabascaBasin #Uranium #REE #DiamondDrilling #Exploration #MiningNews #ResourceStocks #Geophysics #RareEarthElements #MineralExploration #KeyLakeMine #JuniorMining #DrillProgram #MiningUpdate #RadioactiveRocks #EnergyMetals #NaturalResources
