Tudor Gold Discovers New Copper-Gold Porphyry System and Confirms Gold-Silver Epithermal Trend Within Treaty Creek’s Perfectstorm Zone

Date: 7 August 2026

Tudor Gold Corp. reports 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.

See Table 1 below for select drill results of holes PS-26-15 to 18 accompanied by plan maps and cross sections.

PSP Zone – New porphyry discovery along Sulphurets corridor

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 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 – Continuity of epithermal-style gold-dominant system validated

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 meters. Hole PS-23-10 drilled in 2023 intersected 1.23 g/t gold and 3.43 g/t silver over 120.15 meters, and hole PS-21-06 drilled in 2021 intersected 0.84 g/t gold and 6.09 g/t silver over 59.90 meters including 2.52 g/t gold and 6.64 g/t silver over 5.90 meters. (See news releases dated October 31, 2023 and August 30, 2021.)

Hole PS-26-17 intersected:

0.78 g/t gold and 2.90 g/t silver over 74.15 meters starting 86.45 meters downhole, including
- 2.16 g/t gold and 3.18 g/t silver over 9.10 meters starting 151.50 meters downhole

(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.
