Tudor Gold Expands Treaty Creek’s Perfectstorm Zone Copper-Gold Porphyry System and Potential for Broader Gold-dominant Epithermal System
Vancouver, British Columbia–(Newsfile Corp. – September 17, 2026) – Tudor Gold Corp. (TSXV: TUD) (FSE: H56) (the “Company” or “Tudor“) reports results from ten drill holes drilled at the Perfectstorm Zone as part of the 2026 Treaty Creek Project Exploration Program. Drilling has expanded the recently discovered copper-gold-silver-molybdenum porphyry system (the “PSP Zone”) and confirmed the potential for continuity of the near-surface gold-dominant mineralization in the epithermal system (the “PSE Zone”). Tudor’s 80%-owned Treaty Creek Project is located in the heart of the Golden Triangle of Northwestern British Columbia.
See Table 1 below for select drill results of holes PS-26-19 to 28 accompanied by plan maps and cross sections.
PSP Zone – Continued Expansion of the Porphyry System
Hole PS-26-19 intersected:
- 0.21 g/t gold, 1.66 g/t silver, 0.26% copper and 58.39 ppm molybdenum, over 89.65 meters starting 178.00 meters downhole, including
- 0.30 g/t gold, 2.64 g/t silver, 0.45% copper and 54.92 ppm molybdenum over 18.65 meters starting 249.00 meters downhole
Hole PS-26-23 intersected:
- 0.26 g/t gold, 2.13 g/t silver, 0.25% copper and 23.05 ppm molybdenum, over 100.30 meters starting 166.50 meters downhole, including
- 0.30 g/t gold, 2.36 g/t silver, 0.30% copper and 52.39 ppm molybdenum, over 57.60 meters starting 209.20 meters downhole, and
- 0.35 g/t gold, 3.10 g/t silver, 0.48% copper and 72.71 ppm molybdenum, over 12.00 meters starting 222.00 meters downhole
- 0.98 g/t gold and 9.39 g/t silver over 101.00 meters starting 293.50 meters downhole, including
- 2.01 g/t gold and 32.15 g/t silver over 25.50 meters starting 351.00 meters downhole, and
- 5.15 g/t gold and 171.68 g/t silver over 4.50 meters starting 372.00 meters downhole
Hole PS-26-27 intersected:
- 0.26 g/t gold, 2.32 g/t silver, 0.29% copper and 50.39 ppm molybdenum, over 76.55 meters starting 211.15 meters downhole, including
- 0.35 g/t gold, 2.53 g/t silver, 0.44% copper and 61.72 ppm molybdenum, over 23.70 meters starting 264.00 meters downhole
- 0.89 g/t gold and 3.40 g/t silver over 32.00 meters starting 411.00 meters downhole, including
- 3.60 g/t gold and 7.18 g/t silver over 2.00 meters starting 439.45 meters downhole
Hole PS-26-28 intersected:
- 3.51 g/t gold and 4.04 g/t silver over 11.50 meters starting 173.00 meters downhole, including
- 4.85 g/t gold and 5.79 g/t silver over 6.00 meters starting 175.50 meters downhole
- 1.12 g/t gold and 7.04 g/t silver over 66.70 meters starting 377.00 meters downhole, including
- 44.38 g/t gold and 440.00 g/t silver over 0.80 meters starting 434.50 meters downhole
Results from holes PS-26-19, PS-26-21, PS-26-23, PS-26-25, PS-26-27, and PS-26-28 demonstrate consistent gold, silver, copper, and molybdenum values hosted within a potassic altered diorite (porphyry) intrusive. Similar to the neighbouring Goldstorm Deposit, the newly discovered porphyry intrusive is located between higher-grade intervals of gold-dominant mineralization. Continued intercepts of higher-grade material demonstrate early continuity of a high-grade gold-dominant overprint to the porphyry system. The PSP Zone is located approximately one kilometer southwest of Treaty Creek’s Goldstorm Deposit at its closet point and 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.
PSE Zone – Broader Zones of Epithermal-style Gold-dominant Mineralization
Hole PS-26-20 intersected:
- 0.82 g/t gold and 2.52 g/t silver over 81.00 meters starting 78.00 meters downhole, including
- 2.94 g/t gold and 3.60 g/t silver over 7.50 meters starting 90.00 meters downhole
Hole PS-26-22 intersected:
- 4.19 g/t gold and 11.20 g/t silver over 3.00 meters starting 465.00 meters downhole
- 1.40 g/t gold and 3.65 g/t silver over 7.20 meters starting 432.80 meters downhole
Hole PS-26-24 intersected:
- 1.10 g/t gold and 0.85 g/t silver over 31.50 meters starting 154.50 meters downhole, including
- 6.22 g/t gold and 1.27 g/t silver over 3.00 meters starting 183.00 meters downhole
Drillhole PS-26-20 intersected a broad zone of near surface, gold-dominant epithermal vein-hosted mineralized system, adding to the volume of the previously identified mineralized system. Holes PS-26-22, PS-26-24, and PS-26-26 intersected several higher-grade gold-dominant intervals confirming the potential continuity of the vein hosted system.
Surface sampling in an area located 1.2 kilometers northwest of current Perfectstorm drilling has returned results up to 13.54 g/t gold, expanding the potential mineralized footprint of the system. Four near-surface drill holes have been drilled to follow-up, with results to be reported on receipt. The two drills remain active at the Perfectstorm Zone and are focused on priority target areas identified by recent results.

(1) All assay values are uncut, and intervals reflect drilled intercept lengths. True widths have not been determined as the mineralized body remains open in all directions. Further drilling is required to determine the mineralized body orientation and true widths.
(2) HQ and NQ diameter core samples were sawn in half and typically sampled at standard 1.5 meters intervals.

QA/QC
Diamond drill core 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.
