Collective Metals Initiates Inaugural Drill Program at the
Rocas Uranium Project in Southeast Athabasca Basin
March 17, 2026
Highlights:
• Drilling Underway: Drilling activities began on March 16th, 2026. Drill holes have been designed to target shallow
high-grade* basement-hosted uranium mineralization across multiple high-priority target areas. The Program is
anticipated to span approximately five (5) weeks.
• Robust & Shallow Drill Targets: The Phase I program will be comprised of approximately 1,200 to 1,500 metres of
diamond drilling across six (6) to eight (8) drill holes. Targets are located at shallow depths less than two hundred
(200) metres below surface.
• Untested Structural Corridors: For the first time in the Project’s history, the Company will drill test the 7.5 -
kilometre electromagnetic (“EM”) corridor on Rocas. This structural trend hosts historical surface mineralization
with grab samples returning up to 0.50% U3O8 and recent high-gradeǂ rare earth element (“REE”) results up to
9.83% TREO* and up to 0.41% U3O8 from 2025 prospecting.1,2
• Untapped Uranium Potential: One diamond drill will focus on high-priority target areas along prospective VTEM
corridors overlain by high-resolution ground gravity data with the proven exploration thesis of focusing on major
conductor trends associated with cross-cutting faults and surficial radioactivity expressions.
VANCOUVER, B.C. – COLLECTIVE METALS INC. (CSE: COMT | OTC: CLLMF | FSE: TO1) (the “Company” or “Collective”) is
pleased to announce that drilling activities have commenced at the Company’s Rocas Uranium Project (“Rocas”, or the
“Project”) located 75 kilometers southwest of the Key Lake Mine and Mill facilities along Highway 914 (Please see Figure 1).
Field crews have arrived at the Project and drilling has commenced on schedule.
Christopher Huggins, Chief Executive Officer of the Company, commented, “With multiple high-priority targets defined
through geophysics, surface mineralization, and recent prospecting, we believe Rocas has the potential to host shallow, high-
grade uranium mineralization. We look forward to testing these targets and advancing the Project in one of the world’s
premier uranium districts.”

2026 Drill Program
The Standard Uranium Ltd. (“Standard”) team arrived on site on March 16th and diamond drilling on the first hole in history
at Rocas is currently underway. The winter/spring program will be comprised of approximately 1,200 to 1,500 metres of
drilling at high-priority target areas following completion of a ground gravity survey and multifaceted geophysical modeling
last year (the “Program”). Rocas covers an area of 4,002 hectares across three (3) mineral claims, located along highway
914 south of the Key Lake Mine and Mill facilities in the southeastern Athabasca Basin region.
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.2

Target Selection for 2026 Drill Campaign
Targets were selected and prioritized through an iterative approach working in collaboration with Convolutions Geoscience
Corporation. Prospecting and mapping across the Project in fall 2025 outlined multiple outcrops of favourable uranium and
REE host-rocks, including radioactive metasediments, pegmatites, and structured orthogneiss. Structural measurements,
assay results, and radioactivity mapping has further refined drill targets in the 2026 target areas.
Targets are ranked and prioritized based on geophysical signature, geological/structural setting, proximity to surficial
uranium occurrences of interest, historical lakebed geochemistry, and Standard’s recent prospecting and mapping campaign
on behalf of the Company.

Qualified Person Statement
The scientific and technical information contained in this news release has been reviewed, verified, and approved by Sean
Hillacre, P.Geo., President and VP Exploration of 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’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 factors 3 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 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”.
ǂThe Company considers REE mineralization with concentrations greater that 1.0 wt.% TREO* to be “high-grade”.
