Collective Metals Confirms Anomalous Uranium and High-Grade Rare Earth Element Mineralization up to 9.83% TREO* at Surface on the Rocas Project

Executive Summary
- Final assay results from the 2025 surface prospecting program at the Rocas Uranium Project show high‑grade REE mineralization up to 9.83 % TREO* and uranium concentrations as high as 0.409 % U₃O₈ in outcrop/boulder grab samples.
- A newly identified pegmatite outcrop yielded 9.83 % TREO* and 0.016 % U₃O₈, confirming the coexistence of significant REE and uranium mineralization across the project.
- The company will commence its inaugural diamond‑drill program in March 2026 to test high‑priority targets along a 7.5 km magnetic low/EM conductive corridor that hosts multiple historic showings.
Key Details
- Assay Highlights (16 samples):
- Sample 244980 – Outcrop – 0.016 % U₃O₈, 9.833 % TREO* (highest REE grade).
- Sample 244986 – Boulder – 0.409 % U₃O₈, 0.084 % TREO*.
- Additional outcrop grades: 0.007–0.195 % U₃O₈; TREO* up to 1.354 %.
-
Boulder grades: U₃O₈ from <0.001 to 0.409 %; TREO* up to 4.589 %.
-
Uranium Range Across Project: 0.007 % – 0.409 % U₃O₈ in surface grab samples.
-
New Radioactive Showings: Scintillometer surveys (Fall 2025) identified previously undocumented radioactive anomalies in rock types favorable for uranium and REE mineralization.
-
Upcoming Drilling (March 2026):
- First ever diamond‑drill program on Rocas.
-
Targets: high‑priority zones along the main 7.5 km magnetic low/EM conductive corridor, coincident with gravity lows, cross‑cutting structures, and known uranium/REE occurrences.
-
Geophysical Work (2025):
- High‑resolution ground gravity survey by MWH Geo‑Surveys; processing by Convolutions Geoscience identified several gravity lows aligning with surface mineralization and lakebed geochemical anomalies.
-
Airborne EM surveys (2017) defined conductive trends west of the Key Lake Road shear zone, indicating structural widening and subsidiary cross‑cutting structures.
-
Historical Context:
- Historical outcrop grab samples over ~900 m strike length have returned up to 0.498 % U₃O₈ but remain undrilled.
-
Project sits ~75 km SW of Key Lake Mine, within the Athabasca Basin margin, offering shallow drill targets with minimal glacial till cover.
-

Notable Quotes
“Confirming high‑grade REE mineralization up to 9.83 % TREO at surface alongside widespread uranium across Rocas significantly enhances the Project’s discovery potential. As we mobilize for our inaugural drill program, Rocas stands out as a highly prospective, shallow uranium target in the Athabasca Basin.” – Christopher Huggins*, CEO, Collective Metals Inc.
