Collective Metals intercepts anomalous radioactivity at Rocas Uranium Project

Highlights Program Completion: A total of 962 metres were completed across four (4) reconnaissance drill holes at the Upper Prawn Lake, Southside, and Crab Lake target areas (Please see Figure 1). Anomalous Radioactivity: Multiple intervals of anomalous* radioactivity exceeding 300 counts per second (“ cps ”) were intersected in three (3) of the four (4) holes, totalling 1.5 metres of composite radioactivity. Geochemical assays are pending.

Geophysical Correlation: The intersection of graphitic metasediments and associated sulphide mineralization in all four (4) holes validates the Project’s electromagnetic (“ EM ”) signatures and confirms the accuracy of the current geophysical model. Significant graphitic sequences are confirmed in ROC-26-001 (0-76 m) and ROC-26-003 (36-84 m), with graphitic fault gouge also present in ROC-26-004. Structural Corridors: Brittle graphitic structures and clay gouge indicate structural reactivation and the conduits necessary for mineralizing fluids.

Secondary hematite and clay alteration confirm hydrothermal processes - a key indicator for uranium deposition. Future Work: A phase two drilling program is currently being designed to follow up on this reconnaissance work. The integration of these latest results will refine and test additional regional targets across more than five (5) km of untested conductor strike-length.

VANCOUVER, British Columbia, May 06, 2026 (GLOBE NEWSWIRE) -- COLLECTIVE METALS INC. (CSE: COMT | OTC: CLLMF | FSE: TO1 ) (the “ Company ” or “ Collective ”) is pleased to announce that drilling activities have been completed at the Company’s Rocas Uranium Project (“ Rocas ”, or the “ Project ”) located seventy-five (75) kilometers southwest of the Key Lake Mine and Mill facilities along Highway 914. The inaugural drilling program targeted anomalies derived from the 2025 prospecting results and integrated geophysical data, including recent ground gravity and historical VTEM anomalies. The Project is currently under a three-year earn-in option agreement (the “ Option Agreement ”) with Standard Uranium Ltd. (“ Standard ”).

Christopher Huggins, Chief Executive Officer of the Company, commented, “The completion of our inaugural drill program at Rocas marks an important step in advancing what we believe is a highly prospective uranium system. Intersecting anomalous radioactivity alongside reactivated graphitic structures across multiple targets validates our exploration model and reinforces the scale potential of the Project.” Figure 1. Regional overview of the Rocas Project along Highway 914 Figure 2 .

Rocas Project overview, highlighting target areas tested during the 2026 drill program 2026 Drill Program – Preliminary Results The winter drilling program (the “ Program ”) totaled 962 meters across four (4) reconnaissance drill holes. Three (3) holes intersected anomalous* radioactivity and all four (4) contain reactivated graphitic structures. This inaugural Program tested three (3) high-priority target areas identified by integrating 2025 ground gravity data, historical VTEM electromagnetics, and surface geological information and mineralization recorded during the 2025 prospecting program. 1 Radiometric results and drill hole data are provided in Table 1.

The four (4) completed drill holes encountered highly favorable geological settings for basement-hosted uranium deposits, including: Graphitic metasediments: Combined intersection downhole thickness of 114 m across all four (4) drillholes, including local fault zones featuring brittle reactivation and graphitic fault gouge, breccias, and cataclasites. Most notable is a 9-metre graphitic fault zone in ROC-26-003 (73-82 m) characterized by dark charcoal-gray cataclastic matrix with 5-10 cm graphitic fault gouge intervals and minor pyrite and pyrrhotite - a highly prospective structural setting for uranium. Accompanying clay alteration and hydrothermal hematite observed locally.

Hydrothermal Alteration : Key alteration includes clay replacement, chlorite, carbonate, and secondary hematite in and surrounding the above-mentioned graphitic fault zones, providing evidence of the hydrothermal processes required for uranium deposition. Anomalous Radioactivity: Multiple intervals of anomalous* radioactivity, with notable intersections including 0.5 m up to 360 cps in ROC-26-003 (40.5-41.0 m), 0.5 m up to 320 cps in ROC-26-004 (71.0-71.5 m), and 0.5 m at peak 650 cps in ROC-26-001 (208.5-209.0 m) totalling 1.5 metres of composite anomalous radioactivity.

Drill core photo from ROC-26-003: Clay-altered graphitic pelitic gneiss (yellow), with reactivated gouge/cataclasite intervals (black), carbonate veining, and bounding hydrothermal hematite alteration (red) Next Steps & Follow Up Building on the success of the 2026 Program, the Company and its partner, Standard Uranium Ltd., are planning follow-up activities to expand upon recent results: Regional Prospecting: Continued mapping and sampling will be conducted on radioactive anomalies identified during the 2025 season to refine drill targets.

Systematic Corridor Testing: Future drilling will move systematically along the remaining untested 5 km of the 7.5 km EM corridor, focusing on extrapolated conductors and areas with anomalous geochemistry and surface Uranium/Rare Earth Element mineralization. Geophysical Expansion: The Company intends to expand ground gravity and EM coverage to the north and south of the current target areas to identify additional structural offsets and traps for uranium mineralization. Drill core samples have been collected systematically for whole-rock multi-element geochemical analysis and submitted to SRC Geoanalytical Laboratories in Saskatoon for U 3 O 8 and Rare Earth Element (“ REE ”) assay.

These results will be integrated with detailed logging and structural modelling to prioritize follow-up target areas. The Project is positioned near the margin of the Athabasca Basin, where bedrock is covered by minimal glacial till. The 2017 airborne EM surveys defined conductive trends sub-parallel to the Key Lake Road Shear Zone, suggesting favorable metasedimentary basement lithologies.

The Company believes the combination of cross-cutting structures and significant surficial mineralization makes the Project highly prospective for shallow, high-grade** basement-hosted uranium.
