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

Highlights:

• Uranium and High-Grade REE Mineralization at Surface: Significant REE mineralization grades associated with varying uranium concentrations of uranium hosted in outcrop and boulder grab samples has been confirmed across the Project, including a newly identified pegmatite outcrop with assay results up to 9.83% TREO* and 0.016% U3O8 in grab sample. Uranium assays from outcrop and boulder grab samples range across the Project from 0.007% to 0.409% U3O8.
• Discovery of New Radioactive Showings: Scintillometer prospecting conducted in the fall of 2025 uncovered previously undocumented radioactive occurrences across the Project in rock types favorable for uranium and REE mineralization.¹
• Ongoing Exploration: The inaugural diamond drill program at the Project is scheduled to commence in March 2026 and will begin testing high-priority zones along the main 7.5-kilometre magnetic low and EM conductive corridor, which coincides with gravity lows, cross-cutting structures, and several uranium and REE occurrences.
  

VANCOUVER, British Columbia, March 10, 2026 (GLOBE NEWSWIRE) -- COLLECTIVE METALS INC. (CSE: COMT | OTC: CLLMF | FSE: TO1- (the "Company" or "Collective") is pleased to announce final assay results from its 2025 exploration program on the Rocas Uranium Project ("Rocas", or the "Project"), currently under a three-year earn-in option agreement with Standard Uranium Ltd. ("Standard").

The Company completed a detailed mapping and sampling program across historical uranium showings and other zones of interest on the Project during the fall of 2025 (Figure 1). Multiple areas of strong radioactivity were identified, and assay results confirmed anomalous uranium mineralization across the Project. In addition, significant Rare Earth Element ("REE") mineralization was identified, with concentrations reaching high-grade Total Rare Earth Element Oxides plus Yttrium ("TREO*") thresholds.

Christopher Huggins, Chief Executive Officer of the Company, commented "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."

2025 Prospecting Program - Geochemical Assay Results

From September 30 to October 8, 2025, the Standard Uranium technical team completed a detailed mapping, prospecting, and sampling program to verify results from historical uranium showings at surface on the Project (Figure 2). Prospecting confirmed multiple uraniferous outcrops and boulders across the Project, including areas proximal to historical showing SMDI #5781 (0.195% and 0.054% U3O8).² Uranium concentrations of up to 0.409% U3O8 were obtained from outcrop exposures and boulder surface showings. In addition to discovering previously undocumented radioactive anomalies, the program confirmed significant REE mineralization on the Project in both outcrop and boulders, with several samples returning high grades exceeding 1.0% TREO* (Table 1).

A total of 16 outcrop and boulder grab samples were submitted to Saskatchewan Research Council Geoanalytical Laboratories ("SRC") in Saskatoon, SK - an ISO/IEC 17025:2017 and Standards Council of Canada certified analytical laboratory - for whole-rock, uranium, and REE geochemical analysis. Uranium and TREO* results from the 16 radioactive samples are summarized below in Table 1. Oxide TREO* values in Table 1 represent the total amount of rare earth element oxides in the lanthanide series plus the chemically similar element yttrium (Y2O3). Parts per million ("ppm") values were converted to oxide weight percent (wt.%) using the applicable conversion factor for each REE oxide and then summed.³

Rocas 2026 Exploration

The Company recently announced its plans to complete the first ever drill program on the Project in March 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.

In 2025, the Company contracted MWH Geo-Surveys (Canada) Ltd. to carry out a high-resolution ground gravity survey over the Rocas Project⁴, while Convolutions Geoscience Corporation has completed subsequent processing, interpretation, and modelling of the gravity data. The ground gravity survey identified 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. Gravity lows in this geological setting are often associated with reduced rock density which may indicate alteration zones associated with uranium.

Airborne EM surveys conducted 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 indicate structural widening of the trend, and offsets and termination points indicate important subsidiary cross-cutting structures. Additionally, a 2007 field sampling program identified lakebed geochemical anomalies that statistically rank as greater than 95th percentile U, Co, V, and Zn along the conductor corridor, including high U/Th ratios⁵-

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 tested²-

("Standard") and a "qualified person" as defined in NI 43-101 - Standards of Disclosure for Mineral Projects.

Samples collected for analysis were sent to SRC Geoanalytical Laboratories ("SRC") in Saskatoon, Saskatchewan for preparation, processing, and ICP-MS or ICP-OES multi-element analysis using total and partial digestion and boron by fusion. Radioactive samples were tested using the ICP-MS2 uranium multi-element exploration package plus boron. Samples chosen for REE analysis were tested using the REE2 package by ICP-MS. All samples marked as radioactive upon arrival to the lab were also analyzed using the U₃O₈ assay (reported in wt.%). SRC is an ISO/IEC 17025:2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats were inserted into the sample stream at regular intervals in accordance with Standard Uranium's quality assurance/quality control ("QA/QC") protocols. All samples passed internal QA/QC protocols and the results presented in this release are deemed complete, reliable, and repeatable.

REE oxide conversion factors³ were verified using the following formulas:
Convert REE (Rare Earth Element) ppm to REO (Rare Earth Oxide): REO % = (ppm / Atomic Weight of REE) * (Molecular Weight of REO / 10,000).

Element-to-oxide conversion factor: Molecular weight of the oxide / atomic weight of the element. For oxides with more than one metal cation, account for the number of cations in the formula.

Historical data disclosed in this news release relating to sampling results from previous operators are historical in nature. Neither the Company nor a qualified person has yet verified this data and therefore investors should not place undue reliance on such data. The Company's future exploration work may include verification of the data. The Company considers historical results to be relevant as an exploration guide and to assess the mineralization as well as economic potential of exploration projects. Any historical grab samples disclosed are selected samples and may not represent true underlying mineralization.

Natural gamma radiation from rocks reported in this news release was measured in counts per second ("cps") using a handheld RS-125 super-spectrometer and RS-120 super-scintillometer. Readers are cautioned that scintillometer readings are not uniformly or directly related to uranium grades of the rock sample measured and should be treated only as a preliminary indication of the presence of radioactive minerals. The RS-125 and RS-120 units supplied by Radiation Solutions Inc. ("RSI") have been calibrated on specially designed Test Pads by RSI. Standard Uranium maintains an internal QA/QC procedure for calibration and calculation of drift in radioactivity readings through three test pads containing known concentrations of radioactive minerals. Internal test pad radioactivity readings are known and regularly compared to readings measured by the handheld scintillometers for QA/QC purposes.

*The Company considers uranium mineralization with concentrations greater than 1.0 wt% U₃O₈ to be "high-grade".

**The Company considers radioactivity readings greater than 65,535 counts per second (cps) on a handheld RS-125 Super-Spectrometer to be "off-scale".

The Company considers REE mineralization with concentrations greater that 1.0 wt.% TREO* to be "high-grade".
