Tudor Gold discovers new copper-gold porphyry system and verifies gold-silver trend within Treaty Creek’s Perfectstorm Zone, British Columbia

Tudor Gold Corp. [TSXV: TUD; FSE: H56] reported that results from the first four holes drilled at the Perfectstorm Zone as part of the 2026 Treaty Creek Project Exploration Program have led to both the discovery of a new copper-gold-silver-molybdenum porphyry system (the PSP Zone) as well as the confirmation of a previously identified gold-silver-dominant epithermal system (the PSE Zone). The two drills active at the Perfectstorm Zone are now focused on these priority target areas. Tudor’s 80%-owned Treaty Creek Project is located in the heart of the Golden Triangle of northwestern British Columbia.

Results from holes PS-26-15, PS-26-16 and PS-26-18 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.

The PSP Zone is located approximately one kilometer southwest of Treaty Creek’s Goldstorm Deposit at its closet point and 4 km 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.

PSP Zone porphyry system drill results: Hole PS-26-15 intersected 4.59 g/t gold and 0.67 g/t silver over 10.50 metres starting 105.00 metres downhole, including 11.15 g/t gold and 0.84 g/t silver over 3.00 metres starting 105.00 metres downhole; 0.24 g/t gold, 2.11 g/t silver, 0.21% copper and 50.76 ppm molybdenum over 82.90 metres starting 156.00 meters downhole, including 0.23 g/t gold, 3.11 g/t silver, 0.30% copper and 41.34 ppm molybdenum, over 30.85 metres starting 208.05 meters downhole; 0.78 g/t gold and 0.29 g/t silver over 83.10 metres starting 267.90 metres downhole, including 2.73 g/t gold and 3.44 g/t silver over 2.50 metres starting 283.50 metres downhole, and 1.89 g/t gold and 3.00 g/t silver over 9.00 metres starting 342.00 metres downhole.

Hole PS-26-16 intersected 1.23 g/t gold and 2.16 g/t silver over 6.00 metres starting 265.50 metres downhole; 0.36 g/t gold, 1.95 g/t silver, 0.28% copper and 42.52 ppm molybdenum over 10.50 metres starting 331.50 metres downhole; 0.87 g/t gold, 4.33 g/t silver, 0.07% copper and 96.13 ppm molybdenum over 10.50 metres starting 393.00 metres downhole.

Hole PS-26-18 intersected 0.34 g/t gold, 1.89 g/t silver, 0.27% copper and 53.72 ppm molybdenum over 67.35 metres starting 180.00 metres downhole, including 0.46 g/t gold, 3.09 g/t silver, 0.37% copper and 54.51 ppm molybdenum over 16.35 metres starting 231.00 metres downhole.

Drillhole PS-26-17 intersected a near surface, gold-dominant epithermal vein-hosted mineralized system confirming continuity between two previous drillholes along a strike length of over 360 metres. Hole PS-23-10 drilled in 2023 intersected 1.23 g/t gold and 3.43 g/t silver over 120.15 metres, and hole PS-21-06 drilled in 2021 intersected 0.84 g/t gold and 6.09 g/t silver over 59.90 metres including 2.52 g/t gold and 6.64 g/t silver over 5.90 meters.

Hole PS-26-17 intersected 0.78 g/t gold and 2.90 g/t silver over 74.15 metres starting 86.45 meters downhole, including 2.16 g/t gold and 3.18 g/t silver over 9.10 metres starting 151.50 metres downhole.

Treaty Creek’s Goldstorm Deposit, as disclosed in the “NI 43-101 Technical Report, Treaty Creek Project, British Columbia”, dated November 30, 2025 and prepared by Garth Kirkham P.Geo. of Kirkham Geosystems and Renee Goold (Morrison), P.Eng. of Fuse Advisors, hosts Indicated Mineral Resources of 24.9 million ounces of gold, 148.7 million ounces of silver and 3.048 billion pounds of copper (912.3 million tonnes grading 0.85 g/t gold, 5.07 g/t silver and 0.15% 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% 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 underway. In addition to the Goldstorm Deposit, Treaty Creek hosts other gold discoveries nearby: the CBS, Eureka and Perfectstorm zones.

Tudor Gold Corp. holds claims in British Columbia’s Golden Triangle region, an area that hosts producing and past-producing mines and several large deposits that are approaching potential development. The 17,913-hectare Treaty Creek Project (in which Tudor Gold has an 80% interest) borders Seabridge Gold’s KSM property to the southwest and borders Newmont Corporation’s Brucejack Mine property to the southeast.
