Tudor Gold Expands Perfectstorm Zone Porphyry System, Confirms Potential for Broader Gold-Dominant Epithermal System at Treaty Creek

• Tudor Gold Corp. reported results from 10 drill holes at the Perfectstorm Zone within the 2026 Treaty Creek Project exploration program, expanding the copper-gold-silver-molybdenum porphyry system (PSP Zone) and confirming continuity potential for the near-surface gold-dominant epithermal system (PSE Zone).
• One porphyry-zone hole intersected 101.00 meters grading 0.98 grams per tonne gold and 9.39 grams per tonne silver, including a higher-grade 4.50-meter interval of 5.15 grams per tonne gold and 171.68 grams per tonne silver.
• Another hole returned 66.70 meters at 1.12 grams per tonne gold and 7.04 grams per tonne silver, including a narrow but very high-grade 0.80-meter interval grading 44.38 grams per tonne gold and 440.00 grams per tonne silver.
• Surface sampling 1.2 kilometers northwest of the current drilling returned results up to 13.54 grams per tonne gold, expanding the potential mineralized footprint of the system; 4 near-surface follow-up holes have been drilled, with results pending.
• 2 drills remain active at the Perfectstorm Zone, with the PSP Zone located roughly 1 kilometer southwest of Treaty Creek's Goldstorm Deposit and 4 kilometers northeast of Seabridge Gold's Iron Cap Deposit along the Sulphurets corridor.

Company Overview

Tudor Gold Corp. (TSXV: TUD | Frankfurt: H56) is a precious and base metals exploration and development company holding an 80% interest in the 17,913-hectare Treaty Creek Project in British Columbia's Golden Triangle. The property borders Seabridge Gold Inc.'s KSM property to the southwest and Newmont Corporation's Brucejack Mine to the southeast. Treaty Creek's Goldstorm Deposit hosts Indicated Mineral Resources of 24.9 million ounces of gold, 148.7 million ounces of silver and 3.048 billion pounds of 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, per the NI 43-101 Technical Report dated November 30, 2025. A Preliminary Economic Assessment (PEA) for placing Goldstorm into underground production is underway, alongside a permit application to construct an underground ramp to access the high-grade gold SC-1 Zone.

A Second Mineralized System Taking Shape at Perfectstorm

The 10-hole batch confirms two distinct but related mineralized styles at Perfectstorm: a copper-gold-silver-molybdenum porphyry system (PSP Zone) and a near-surface, gold-dominant epithermal vein system (PSE Zone). The PSP Zone is located roughly 1 kilometer southwest of the Goldstorm Deposit and 4 kilometers northeast of Seabridge Gold's Iron Cap Deposit, along the same northeast-southwest trending Sulphurets corridor that hosts both. The PSP Zone remains open in all directions, meaning the porphyry system has not yet been bounded by drilling.

PSP Zone: Porphyry System Continues to Grow

Multiple holes returned consistent gold, silver, copper, and molybdenum values hosted within a potassic-altered diorite intrusive. One hole intersected 100.30 meters grading 0.26 grams per tonne gold, 2.13 grams per tonne silver, 0.25% copper and 23.05 parts per million molybdenum, including a higher-grade 57.60-meter interval at 0.30 grams per tonne gold, 2.36 grams per tonne silver, 0.30% copper and 52.39 parts per million molybdenum. The same hole also returned a separate, higher-grade interval of 101.00 meters at 0.98 grams per tonne gold and 9.39 grams per tonne silver, including 4.50 meters at 5.15 grams per tonne gold and 171.68 grams per tonne silver.

Similar to the neighboring Goldstorm Deposit, the newly discovered porphyry intrusive sits between higher-grade intervals of gold-dominant mineralization, an early indication of continuity between the porphyry system and a high-grade gold overprint. A separate hole reinforces this pattern: an upper interval of 11.50 meters graded 3.51 grams per tonne gold, and the same hole returned 66.70 meters at 1.12 grams per tonne gold and 7.04 grams per tonne silver, including a 0.80-meter interval grading 44.38 grams per tonne gold and 440.00 grams per tonne silver.

PSE Zone: Confirming a Broader Epithermal Footprint

Separately, drilling targeted the near-surface, gold-dominant epithermal system first identified at Perfectstorm. One hole intersected a broad 81.00-meter interval grading 0.82 grams per tonne gold and 2.52 grams per tonne silver, including 7.50 meters at 2.94 grams per tonne gold and 3.60 grams per tonne silver, adding volume to the previously identified mineralized system. Two other holes returned narrower but higher-grade intervals, including 3.00 meters at 4.19 grams per tonne gold and 11.20 grams per tonne silver in one hole, and 3.00 meters at 6.22 grams per tonne gold and 1.27 grams per tonne silver within a broader 31.50-meter interval in another. Tudor Gold characterizes these results as confirming potential continuity of the vein-hosted epithermal system across the zone.

Surface Sampling Widens the Target Area

Surface sampling 1.2 kilometers northwest of the current Perfectstorm drilling returned results up to 13.54 grams per tonne gold, expanding the potential mineralized footprint of the system. Four near-surface holes have already been drilled to follow up on this sampling, with results pending.

Next Steps

Assay results are pending from the 4 near-surface follow-up holes, and 2 drills remain active at the Perfectstorm Zone, focused on priority target areas identified by the latest results.
