Tudor Gold Extends Perfectstorm 480 Meters Down-Dip as Its PEA Nears

Tudor Gold has reported 4 new holes from the Perfectstorm Zone at its Treaty Creek Project in British Columbia's Golden Triangle, extending gold-dominant mineralization in the newly discovered porphyry system more than 480 meters (m) down-dip of earlier drilling. The holes also added higher-grade intercepts that tie a gold overprint (later gold mineralization laid over the porphyry) to the system, much like the nearby Goldstorm Deposit. The near-surface gold zone was also extended along strike, meaning along its length. Three drill rigs are now turning at Perfectstorm, and a preliminary economic assessment (PEA) on an underground mine at Goldstorm is being finalized.

Company Overview

Tudor Gold (TSXV: TUD) is a precious and base metals exploration and development company with claims in British Columbia's Golden Triangle, an area that hosts producing and past-producing mines and several large deposits with development potential. The company holds an 80% interest in the 17,913-hectare Treaty Creek Project, which borders Seabridge Gold's KSM property to the southwest and Newmont Corporation's Brucejack Mine property to the southeast. The Goldstorm Deposit at Treaty Creek hosts indicated mineral resources of 24.9 million ounces (Moz) of gold, 148.7 Moz of silver, and 3.048 billion pounds (lb) of copper, and inferred mineral resources of 2.6 Moz of gold, 7.2 Moz of silver, and 67.9 million lb of copper. The deposit remains open in all directions.

Porphyry System Extends 480 Meters Down-Dip

The 4 holes form part of the 2026 Treaty Creek exploration program and tested both the near-surface PSE Zone and the PSP Zone, a copper-gold-silver-molybdenum porphyry system recently discovered at Perfectstorm. A porphyry is a large body of mineralized intrusive rock. The hole designed to test the system's down-dip continuity, meaning its extension along the slope of the body at depth, cut gold-dominant mineralization more than 480 meters (m) beyond previous drilling.

That hole returned 0.98 grams per tonne (g/t) gold and 3.29 g/t silver over 31.80 m from 646.90 m downhole, including 3.98 g/t gold and 14.72 g/t silver over 4.20 m. Deeper still, it cut 15.05 g/t gold and 5.33 g/t silver over 1.50 m from 913.50 m downhole. Shallower in the same hole, a vein-hosted interval graded 3.43 g/t gold and 7.99 g/t silver over 2.65 m from 267.35 m downhole, among several higher-grade intervals that open a large target-rich area across the greater Perfectstorm Zone.

Assays are uncut, meaning high values were not capped, and true widths, the actual thickness of the mineralized body, are not yet determined. The PSP Zone now measures approximately 850 by 750 m and remains open in all directions. It sits approximately 1 kilometer (km) southwest of the Goldstorm Deposit at its closest point and 4 km northeast of Seabridge Gold's Iron Cap Deposit, along the northeast-southwest Sulphurets corridor that hosts multiple porphyry deposits and prospects.

Higher-Grade Gold Overprint Mirrors Goldstorm

Results across 3 of the new holes show consistent gold, silver, copper, and molybdenum values hosted within an altered diorite intrusive, the rock that forms the porphyry. As at Goldstorm, the porphyry intrusive lies between higher-grade intervals of gold-dominant mineralization, and the latest intercepts add continuity to a high-grade gold-dominant overprint on the system.

One hole returned 0.85 g/t gold and 2.94 g/t silver over 96.30 m from 264.30 m downhole, including 2.02 g/t gold over 5.30 m and 1.92 g/t gold over 6.70 m. Another cut 1.16 g/t gold, 0.21% copper, and 116.91 parts per million molybdenum over 11.00 m from 115.00 m downhole. It then cut 0.22 g/t gold, 0.19% copper, and 25.10 parts per million molybdenum over 59.50 m from 141.00 m, including 0.36% copper over 18.00 m. Deeper in that hole, 0.67 g/t gold and 3.72 g/t silver over 37.50 m from 247.00 m included 1.20 g/t gold and 13.41 g/t silver over 7.50 m.

Near-Surface Gold Zone Broadens

Drilling also extended the near-surface, gold-dominant, vein-hosted PSE Zone along strike. The new hole returned 1.16 g/t gold and 13.92 g/t silver over 25.50 m from 238.50 m downhole, including 4.38 g/t gold and 81.97 g/t silver over 3.00 m.

Mineralization in the PSE Zone now covers approximately 600 m by 300 m and ranges in thickness from 25 m to over 100 m. The extension adds to the volume of the previously identified near-surface system.

Goldstorm Mine Study in Final Stage

Tudor Gold has retained Fuse Advisors Inc. to prepare a preliminary economic assessment (PEA) examining the potential for an underground mining operation focused on the higher-grading gold mineralization at Goldstorm outlined in its 2026 mineral resource estimate, announced on January 22, 2026. The study is being finalized.

Alongside the PEA, the company has filed a permit application to construct an underground ramp to access the high-grade gold SC-1 Zone for drilling.

Next Steps

Three drill rigs are now active at the Perfectstorm Zone, focused on priority target areas identified by the recent results. Tudor Gold expects to complete over 20,000 m of drilling with those rigs to finish the remainder of the 2026 exploration program.
