Collective Metals Confirms Strong Radioactivity at Surface

During Successful Exploration Program at the Rocas

Uranium Project

October 16, 2025

VANCOUVER, B.C. – COLLECTIVE METALS INC. (CSE: COMT | OTC: CLLMF | FSE: TO1) (the “Company” or “Collective”) is

pleased to announce preliminary results from its 2025 exploration program at the Rocas Uranium Project (“Rocas”, or the

“Project”), currently under a three -year earn-in option agreement with Standard Uranium Ltd . (“Standard”) (CSE: STND).

From September 30th to October 8th, 2025, the Company completed a detailed mapping and sampling program across

historical uranium showings and zones of interest on the Project, identifying multiple zones of strong radioactivity.

Highlights:

• Strong Radioactivity at Surface – Verification of strong radioactivity at multiple historical uranium showings, with

several handheld scintillometer measurements exceeding 10,000 counts per second (“cps”) at surface.

• Discovery of New Radioactive Showings – Scintillometer prospecting identified previously undocumented

radioactive anomalies across the Project area within lithologies favorable for uranium and Rare Earth Element

(“REE”) mineralization.

• Prime Location – Geological mapping along structural and electromagnetic (“EM”) trends across the Project

confirmed the presence of deformed and hydrothermally altered basement lithologies along more than 7.5 km of

exploration strike length south of Key Lake.

• New Uranium Targets – Results from a high-resolution ground gravity survey completed in 2024 highlight potential

alteration halos and high -priority exploration targets along well -defined structural corridors. A diamond drill

program is planned for 2026 to test targets identified and prioritized through detailed exploration activities carried

out this year.

Christopher Huggins, Chief Executive Officer of the Company, commented, “We are very excited to have confirmed

encouraging radioactive presence at the Rocas Uranium Project during our recently completed mapping and sampling

program, in partnership with Standard Uranium. Moving forward, we feel well prepared to follow up severa l prospective

uranium targets, identified in 2024, during a planned diamond drill program in 2026.”

2025 Prospecting Program – Preliminary Results

The Rocas project comprises 4,002 hectares, located 75 kilometers southwest of the Key Lake Mine and Mill facilities along

Highway 914, and approximately 72 kilometers south of the present-day margin of the Athabasca Basin (Figure 1). Beginning

September 30th and concluding October 8th, 2025, the Standard Uranium technical team completed a detailed mapping,

prospecting, and sampling program to ground-truth historical uranium showings at surface on the Project.

• A total of 16 outcrop and boulder grab samples have been submitted to Saskatchewan Research Council

Geoanalytical Laboratories in Saskatoon, SK for whole-rock, uranium, and REE geochemical analysis.

• Prospecting confirmed several uraniferous outcrops and boulders across the Project, including SMDI showing

5781 (1,100 ppm U)1. Anomalous* radioactivity with a peak of >33,000 cps was measured at SMDI showing 5781

(Figure 2) with several other instances of elevated radiometry were noted, locally up to 26,000 cps.

• A total of 73 handheld scintillometer readings of anomalous radioactivity >300 cps were recorded, including 10

measurements >10,000 cps at surface (Figure 3). Prospecting for radioactive boulders and outcrop was

completed using handheld RS-120 Super-Scintillometers and RS-125 Super-Spectrometers manufactured by

Radiation Solutions Inc. (“RSI”).

• More than 150 detailed geological observations, structural measurements, and scintillometer readings were

taken from several outcrops across the Project within the target areas, identifying deformed and hydrothermally

altered basement lithologies associated with radioactivity (Figure 4).

Figure 2. Investigation at SMDI showing 5781 (13V 416713 E, 6274629 N) returned strong radioactivity across an area of

35 m. Scintillometer readings ranging from: A) 26,900 cps, B) 25,400 cps, and C) 33,000 cps.

Rocas Project Exploration

The Company plans to complete the first ever drill program on the Project in 2026 to begin testing high-priority zones

along the main 7.5 kilometre magnetic low/EM conductive corridor, which is host to several uranium showings and has

remained un-drill tested to date.

• Earlier this year, the Company contracted MWH Geo-Surveys (Canada) Ltd. to carry out a high -resolution ground

gravity survey over the Rocas Project 2, while Convolutions Geoscience Corporation has completed subsequent

processing, interpretation, and modelling of the gravity data. The ground gravity survey outlines several gravity low

anomalies coincident with historical surface mineralization, lakebed geochemical anomalies, and cross-cutting fault

zones along the known conductive exploration trends on the Project.

• Historical airborne EM work in 2017 defined conductive trends on the Project west of and sub -parallel to the Key

Lake Road shear zone, corresponding with favourable metasedimentary basement lithologies. Multiple parallel

conductors, offsets, and terminatio n points indicate the trend widening and potential cross -cutting structures.

Additionally, a 2007 field sampling program identified anomalous lakebed geochemical anomalies that statistically

rank as greater than 95th percentile U, Co, V, and Zn along the conductor corridor, including high U/Th ratios.3

The Company believes the Project is highly prospective for the discovery of shallow, high-grade** basement-hosted uranium

mineralization. Positioned proximal to the margin of the Athabasca Basin, Rocas boasts shallow drill targets with bedrock

under minimal glacial till cover. Historical mineralized outcrop grab samples along approximately 900 metres of strike length,

returned values ranging from 587 ppm U (SN85073) up to 0.498 wt.% U3O8 (SN23901) and have never been drill tested.4
