Standard Uranium Completes First Rocas Drill Program Near Key Lake

Standard Uranium has delivered the first drill test of the Rocas Uranium Project in northern Saskatchewan, giving the company a stronger technical footing on a basement-hosted target corridor southwest of one of Canada’s best-known uranium processing hubs.

The company completed 962 metres across four reconnaissance drill holes at the Upper Prawn Lake, Southside and Crab Lake target areas. Three of the four holes intersected anomalous radioactivity above 300 counts per second, totalling 1.5 metres of composite radioactivity, while all four holes encountered graphitic metasediments and associated sulphide mineralisation. Laboratory assays are still pending. 

The result is early-stage, but technically useful. In Athabasca Basin exploration, graphitic basement rocks, structural reactivation, sulphides, alteration and radioactivity are important vectors when integrated with geophysical data.

Standard Uranium said the drilling validated electromagnetic signatures and confirmed the accuracy of its geophysical model, with graphitic sequences intersected in ROC-26-001 and ROC-26-003 and graphitic fault gouge recorded in ROC-26-004. 

Rocas is located about 75 kilometres southwest of the Key Lake Mine and Mill facilities, about 72 kilometres south of the present-day Athabasca Basin margin. The project covers 4,002 hectares and includes a 7.5-kilometre northeast-trending magnetic low/electromagnetic conductor corridor. Historical outcrop grab samples along approximately 900 metres of strike have returned up to 0.5 wt.% U₃O₈, though Standard Uranium cautions that historical occurrences had not been drill-tested before this program. 

The company’s immediate next step is target refinement. Standard Uranium is designing a phase-two drill program that will incorporate the new structural, geological and radiometric information and test additional targets across more than five kilometres of untested conductor strike length. 

Rocas is currently under a three-year earn-in option agreement with Collective Metals Inc., while Standard Uranium holds a wider Athabasca Basin portfolio of more than 232,864 acres. That project-generator model gives the company a relatively broad uranium exploration platform at a time when nuclear fuel security is again moving up the policy and utility procurement agenda. 

The significance lies in the technical confirmation rather than headline grade. No assay-backed uranium grade has yet been released from the 2026 drilling and handheld or downhole radiometric readings are not a substitute for chemical assays.

Even so, the intersection of anomalous radioactivity within graphitic, structurally reactivated basement rocks gives Standard Uranium a more focused exploration model for follow-up drilling.

Rocas adds a live uranium exploration entry in Saskatchewan at a point when the Athabasca Basin remains one of the world’s most important jurisdictions for high-grade uranium discovery, development and long-term nuclear fuel supply.
