[{"type":"text","content":"Refining Drill Targets Ahead of Planned Spring 2026 Program VANCOUVER, British Columbia – TheNewswire - February 17, 2026 — UraniumX Discovery Corp. (CSE: STMN) (OTC Pink: STMFX) (FSE: A41L7T) (the “Company” or “UraniumX”) and F4 Uranium Corp. (“F4”) are pleased to announce the commencement of a four-line, 9.2 line-kilometre Moving Loop Electromagnetic (“MLEM”) ground geophysical survey (the “Program”) at the Murphy Lake Property (the “Murphy Lake”) in Saskatchewan’s Athabasca Basin. The Program, conducted by EarthEx Geophysical Solutions, is designed to refine conductor targets identified by prior geophysical work and historic drilling ahead of the Company’s planned drill program in late spring 2026. Murphy Lake is located approximately 5 km south of IsoEnergy’s (TSX: ISO) Hurricane Deposit (the “Hurricane Deposit”) and 4 km east of Cameco’s (TSX: CCO) La Rocque Lake Uranium Zone. Background — Previous Exploration Results Previous drilling completed by F4 at Murphy Lake in 2022 comprised 14 drill holes totaling 6,850 metres. The historical program intersected elevated uranium geochemistry and alteration features commonly associated with Athabasca Basin uranium mineralization, including hematite and limonite alteration within sandstone and graphitic shear zones. Drill hole ML22-006 contained the most significant result, returning 0.065% U₃O₈ over 2.5 metres (from 322.5 m to 324.5 m), including 0.242% U₃O₈ over 0.5 metres, within a 4.2-metre-wide deformation zone. Drill hole ML22-012, located approximately 1.4 km to the north, returned anomalous uranium geochemistry of 56 ppm U over 0.5 m in sandstone immediately above the unconformity, suggesting the mineralizing system extends along strike. “The 2022 drill program confirmed that Murphy Lake hosts the geological architecture we look for in the Athabasca Basin — graphitic basement conductors, a wide deformation zone with uranium mineralization, and alteration signatures consistent with the unconformity-hosted model. This MLEM survey is the next disciplined step: resolving conductor geometry so we can position drill holes with precision for the spring program,” said Esen Boldkhuu, Chief Executive Officer of UraniumX.
