Standard Uranium Ltd. (TSXV: STND,OTC:STTDF) (OTCQB: STTDF) (FSE: 9SU0) ("Standard Uranium" or the "Company") is pleased to announce that it has signed a definitive property option agreement (the "Option Agreement"), dated September 26, 2025, with Collective Metals Inc. (CSE: COMT) (the "Optionee"), an arms-length party. Pursuant to the Option Agreement, the Optionee has been granted the option (the "Option") to acquire a seventy-five percent interest in the 4,002-hectare Rocas Project ("Rocas" or the "Project") located in the eastern Athabasca Basin region (Figure 1).
Rocas Project Highlights:
- Prime Location – More than 7.5 km of exploration strike length along a strong NE-SW magnetic low trend coincident with EM conductors and cross-cutting faults, providing shallow drill targets south of Key Lake.
- Uranium at Surface – Mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.5 wt.% U3O8 and never drill tested1 (Figure 2).
- 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.
- Inaugural Exploration – The Standard Uranium technical team mobilized to the Project September 30th, 2025, to undertake a detailed mapping, prospecting, and sampling program to ground-truth historical uranium showings at surface.
Sean Hillacre, Standard Uranium President and VP Exploration, stated: "We are very pleased to have executed the Rocas Option deal with our new partners at Collective Metals quickly, allowing our team to get boots on the ground before the snow flies in Saskatchewan. This inaugural program will allow us to build a comprehensive understanding of the geology across Rocas prior to a maiden drill program, in addition to ground-truthing historic uranium occurrences through scintillometer prospecting and re-sampling."

About the Rocas Project
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. The project was acquired via staking in May 2023 and recently expanded by an additional 931 hectares. Standard Uranium holds a 100%-interest in the Property.
The Project covers 7.5 kilometres of a northeast trending magnetic low/electromagnetic ("EM") conductor corridor which hosts several uranium showings, including historical mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.5 wt.% U3O81. Notably, none of the historical uranium occurrences have been drill-tested.
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 termination 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 ratios2.

Exploration Plans
The Company's technical team will mobilize to the Rocas Project on September 30th, 2025, to undertake a detailed mapping, prospecting, and sampling program to ground-truth historical uranium showings at surface. Collected grab samples will be transported to Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, SK for geochemical analysis.
In 2024, the Company contracted MWH Geo-Surveys (Canada) Ltd. to complete a high-resolution ground gravity survey along known conductive exploration trends on the Rocas project. The survey was designed to aid in the identification of potential zones of hydrothermal alteration of host rocks associated with uranium mineralization events.
Multiple new drill target zones have been identified on the Rocas project, outlined via the confluence of low gravity anomalies, historical surface mineralization, lakebed geochemical anomalies, EM conductors, and crosscutting fault zones.
Ongoing geophysical interpretation and modeling is planned throughout 2025 to integrate historical results with newly collected datasets, which will provide high-priority drill targets and significantly derisk the Project prior to modern drilling next year.
The Company believes the Project is highly prospective for the discovery of shallow, high-grade* basement-hosted uranium mineralization. Located south of the current margin of the Athabasca Basin, Rocas boasts shallow drill targets with bedrock under minimal cover of glacial till.
3-Year Earn-In Option

Â
Notes:
(1)Issuable at a deemed price equivalent to the last closing price of the common shares of the Optionee on the Canadian Securities Exchange immediately prior to entering into the Option Agreement.
(2)Issuable at a deemed price equivalent to the volume-weighted average closing price of the common shares of the Optionee on the Canadian Securities Exchange in the thirty (30) trading days immediately prior to issuance.

(4)Subject to a twelve (12) month escrow, with two (2) equal releases on the six (6) and twelve (12) month anniversaries of issuance.
Prior to exercise of the Option, the Company will act as the operator of the Project and will be entitled to charge a 10% fee on expenditures in Year 1, increasing to 12% in Year 2 and Year 3.
Following successful completion of the obligations of the Option (i.e., at the end of Year 3), Optionee will acquire a 75% equity in the Property, with Standard retaining 25% as well as a 2.5% net smelter returns royalty on the Project, of which 1.0% may be purchased back at any time for a one-time cash payment of $1,000,000.

About Standard Uranium (TSXV: STND,OTC:STTDF)
We find the fuel to power a clean energy future
Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world's richest uranium district. The Company holds interest in over 235,435 acres (95,277 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.
Standard Uranium's Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries. However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.
Standard Uranium's eastern Athabasca projects comprise over 43,185 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.
Standard Uranium's Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.
