Toronto, Ontario--(Newsfile Corp. - September 30, 2026) - Thistle Resources Inc. (TSXV: TRCG) (OTCQB: TRCGF) (FSE: BU9) (the "Company" or "Thistle") is pleased to announce the acquisition of the Brunswick East Project Claims. This claim package consists of 62 units covering an area of 13.64 kms², located strategically between the World-Famous Brunswick #12 Mine and our High-Priority Brunswick Antimony Project.

Highlights

• Staked Claim #12639 (13.64 kms²) covering a suite of clastic sedimentary rocks that hosts Sb and Ag mineralization to the south where they are in contact with the Pabineau Granite contact.
• Explored previously for its VMS potential due to the proximity of the Brunswick #12, the recent discovery of Sb to the south along the granite contact makes the ground an attractive addition to the project.
• The acquisition increases the project size to 269 units, covering an area of 59.18 Km².

Patrick J Cruickshank, MBA, President & CEO stated, "We are thrilled to have acquired this strategic project and enhance our footprint adjacent to the world class Brunswick #12 Mine. I consistently hear that the best location to find new deposits is in the shadows of existing deposits. This also almost doubles the size of our Brunswick Antimony Project and secures the entire mineralized contact from the granite intrusion. Acquiring "Brunswick East" claims through the province's lottery staking system (NB eClaims Process) was a spectacular achievement for such a valuable asset with immense potential. We look forward to including this project in our 2027 exploration program."
