TUDOR GOLD EXPANDS FOOTPRINT OF TREATY CREEK'S PERFECTSTORM ZONE WITH DRILL RESULTS INTERSECTING HIGH-GRADE GOLD, 9.00 G/T GOLD OVER 9.50 METERS, INCLUDING 43.29 G/T GOLD OVER 1.20 METERS, DOWN-DIP FROM HIGH-GRADE SURFACE SAMPLES

Tudor Gold Corp. has released results from four holes drilled at the Perfectstorm zone at its 80-per-cent-owned Treaty Creek project in British Columbia's Golden Triangle. Results from drill holes 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-sulphidation system approximately 500 metres northwest of prior drilling on the Perfectstorm copper-gold porphyry system. Additionally, drill hole 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 downdip and along strike and remains open.

The 2026 Treaty Creek exploration program has been completed, with crews currently demobilizing from site. The 2026 program consisted of 22,511 metres 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.

Drill highlights:

• Hole PS-26-34 intersected:
  • 2.25 grams per tonne gold and 3.10 g/t silver over 37.50 metres starting 127.50 metres downhole, including:
    • 5.25 g/t gold and 6.93 g/t silver over 10.50 metres starting 130.50 metres downhole;
    • Including 10.17 g/t gold and 11.85 g/t silver over 4.50 metres starting 136.50 metres downhole.
• Hole PS-26-36 intersected:
  • 0.80 g/t gold and 713.91 g/t silver over 4.20 metres starting 45.00 metres downhole;
  • 9.00 g/t gold and 9.66 g/t silver over 9.50 metres starting 163.50 metres downhole, including:
    • 22.29 g/t gold and 21.52 g/t silver over 3.62 metres starting 165.30 metres downhole;
    • Including 43.29 g/t gold and 16.90 g/t silver over 1.20 metres starting 166.50 metres downhole.
• Hole PS-26-35 intersected:
  • 1.77 g/t gold and 2.31 g/t silver over 21.60 metres starting 366.00 metres downhole, including:
    • 6.89 g/t gold and 5.86 g/t silver over 3.55 metres starting 367.50 metres downhole;
  • 0.93 g/t gold and 3.40 g/t silver over 49.80 metres starting 1,042.95 metres downhole, including:
    • 2.34 g/t gold and 10.16 g/t silver over 3.90 metres starting 1,072.00 metres 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 metres 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. Drill holes PS-26-34 and PS-26-36 were targeted at testing the downdip 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 metres, 190 metres downdip 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 metres. Two subsequent drill holes, 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 metres to the east was identified with results of up to 35.66 g/t gold indicating the possibility of multiple stacked subvertical structures.

Extension of gold-dominant mineralization at depth at PSP zone discovery

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

The PSP zone is located approximately one kilometre southwest of Treaty Creek's Goldstorm deposit at its closest point and approximately four kilometres 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.

Quality assurance/quality control

Diamond drill core and surface rock samples were prepared at MSALABS' preparation laboratory in Terrace, B.C., and assayed at MSALABS' geochemical laboratory in Langley, B.C. All samples were analyzed using four-acid digestion ICP-MS finish and PhotonAssay for gold. Samples returning greater than 10 parts per million 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 MSALABS' personnel cut from assay rejects at the time of preparation. MSALABS' quality system complies with the requirements for the international standards ISO 17025 and ISO 9001. MSALABS is independent of the company.

About Treaty Creek

Treaty Creek's Goldstorm deposit, as disclosed in the "NI 43-101 Technical Report, Treaty Creek Project, British Columbia," dated Nov. 30, 2025, and prepared by Garth Kirkham, PGeo, of Kirkham Geosystems and Renee Goold (Morrison), PEng, of Fuse Advisors, hosts indicated mineral resources of 24.9 million ounces of gold, 148.7 million ounces of silver and 3,048 million pounds of copper (912.3 million tonnes grading 0.85 g/t gold, 5.07 g/t silver and 0.15 per cent copper) and inferred mineral resources of 2.6 million ounces of gold, 7.2 million ounces of silver and 67.9 million pounds of copper (21.8 million tonnes grading 3.64 g/t gold, 10.22 g/t silver and 0.14 per cent copper).

The Goldstorm deposit remains open in all directions, and a permit application has been filed for approval to construct an underground ramp for access to drill the high-grade gold SC-1 zone. A preliminary economic assessment on placing the Goldstorm deposit in production as an underground mine is now under way. In addition to the Goldstorm deposit, Treaty Creek hosts other gold discoveries nearby: the CBS, Eureka and Perfectstorm zones.
