Tudor Gold Corp. (TSX-V: TUD) (FSE: H56) reports results from four holes drilled at the Perfectstorm Zone at its 80%-owned Treaty Creek Project in B.C.’s Golden Triangle. Results from drillholes PS-26-34 and PS-26-36, which were drilled to follow-up on surface sampling completed earlier in the season, have identified a new high-grade low to intermediate sulfidation system approximately 500 meters northwest of prior drilling on the Perfectstorm copper-gold porphyry system. Additionally, drillhole PS-26-35 intersected a continuance of gold-dominant mineralization at depth within the PSP Zone system identified to date. Perfectstorm’s PSP Zone has now been extended down-dip and along strike and remains open.

The 2026 Treaty Creek Exploration Program (the “2026 Program”) has been completed, with crews currently demobilizing from site. The 2026 Program consisted of 22,511 meters of drilling in 44 holes and was successful in discovering a new porphyry system, the PSP Zone, and multiple zones of epithermal gold mineralization at the Perfectstorm Zone. The PSP Zone has been defined by 23 holes announced to date, with a further 19 holes in the queue for assaying at the lab. A maiden Mineral Resource estimate is expected to be prepared for the PSP Zone once all assays have been received from the 2026 Program.

Hole PS-26-36 intersected:

• 0.80 g/t gold, and 713.91 g/t silver, over 4.20meters starting 45.00 meters downhole
• 9.00 g/t gold, and 9.66 g/t silver, over 9.50 meters starting 163.50 meters downhole, including
  • 22.29 g/t gold, and 21.52 g/t silver, over 3.62 meters starting 165.30 meters downhole, including
  • 43.29 g/t gold, and 16.90 g/t silver, over 1.20 meters starting 166.50 meters downhole

Hole PS-26-35 intersected :

• 1.77 g/t gold and 2.31 g/t silver over 21.60 meters starting 366.00 meters downhole, including
  • 6.89 g/t gold and 5.86 g/t silver, over 3.55 meters starting 367.50 meters downhole
• 0.93 g/t gold and 3.40 g/t silver over 49.80 meters starting 1042.95 meters downhole, including
  • 2.34 g/t gold and 10.16 g/t silver, over 3.90 meters starting 1072.00 meters downhole

Northwest Expansion of High-Grade Gold Mineralization at Perfectstorm Zone

Surface prospecting and sampling completed at the Perfectstorm Zone throughout the 2026 Program identified a strongly mineralized vein and breccia system approximately 25 meters in width at surface composed of multiple mineralized structures containing abundant chalcopyrite and galena. Four of the surface samples returned significant gold and silver values of up to 12.90 g/t gold and up to 444 g/t silver indicating a precious metal rich structural system. Drillholes PS-26-34 and PS-26-36 were targeted at testing the down-dip extension of this surface zone. As highlighted above, PS-26-34 cut 10.17 g/t gold and 11.85 g/t silver over 4.50 meters, 190 meters down-dip of the surface expression. PS-26-36 cut both high-grade gold and silver intervals extending the mineralized zone along a strike length of 125 meters. Two subsequent drillholes, PS-26-37 and PS-26-38 have assays pending with intercepts through this zone.

Additional prospecting in the area has returned surface sample results indicating the possibility of multiple high-grade gold and silver mineralized structures throughout the area. Another north-south trending structure occurring 210 meters to the east was identified with results of up to 35.66 g/t gold indicating the possibility of multiple stacked sub-vertical structures.

Extension of Gold Dominant Mineralization at Depth at PSP Zone Discovery

Drillhole PS-26-35 intersected a continuance of gold-dominant mineralization at depth within the PSP Zone system. The drillhole has extended the mineralized footprint by 220 meters at depth from PS-26-21 which intersected 0.85 g/t gold and 4.09 g/t silver over 34.50 meters, including 1.68 g/t gold and 8.77 g/t silver over 7.50 meters (see news release dated September 16, 2026), adding significant volume to the mineralized system, while demonstrating consistent, broad, gold-dominant intercepts.

The PSP Zone is located approximately one kilometer southwest of Treaty Creek’s Goldstorm Deposit at its closest point and approximately four kilometers northeast of Seabridge Gold’s Iron Cap Deposit, along the northeast-southwest trending Sulphurets corridor that hosts multiple porphyry deposits and prospects. The system remains open in all directions.

Qualified Person

The Qualified Person for this news release for the purposes of National Instrument 43-101 is the Company’s Senior Vice President of Exploration, Ken Konkin, P. Geo. He has read and approved the scientific and technical information that forms the basis for the disclosure contained in this news release.

QA/QC

Diamond drill core and surface rock samples were prepared at MSA Labs’ Preparation Laboratory in Terrace, BC and assayed at MSA Labs’ Geochemical Laboratory in Langley, BC. All samples were analyzed using 4-acid digestion ICP-MS finish and PhotonAssayTM for gold. Samples returning greater than 10 ppm gold were analyzed to extinction. Analytical accuracy and precision are monitored by the submission of blanks, certified standards and duplicate samples each inserted every 20 samples by Tudor Gold personnel. Duplicate samples are obtained by MSA Labs’ personnel cut from assay rejects at the time of preparation. MSA Laboratories quality system complies with the requirements for the International Standards ISO 17025 and ISO 9001. MSA Labs is independent of the Company.
