Tudor Gold Intersects 1.70 g/t Gold over 73.50 Meters at Treaty Creek

Vancouver, British Columbia--(Newsfile Corp. - October 8, 2025) - Tudor Gold Corp. (TSXV: TUD) (FSE: H56) (the "Company" or "Tudor") is pleased to announce the results from the third drillhole completed from the 2025 exploration drilling program (the "Program") at its 80%-owned Treaty Creek Project, located in the heart of the Golden Triangle of Northwestern British Columbia.

Drilling Highlights:

Hole GS-25-190 intersected a 70-meter ("m") eastward extension of the 300 Horizon Zone ("300H"), linking mineralized intercepts within 300H and 300 North Zone ("300N") along a potential SC-1 Zone structural corridor. Highlights of the mineralized intercept:

• 1.70 g/t gold, 3.46 g/t silver and 0.01% copper (1.75 g/t gold equivalent ("AuEQ")) over 73.50 m, including:

  • 2.03 g/t gold, 2.06 g/t silver and 0.01% copper (2.06 g/t AuEQ) over 38.0 m, including:

    • 2.58 g/t gold, 3.01 g/t silver and 0.01% Cu (2.62 g/t AuEQ) over 8.00 m; and

    • 4.41 g/t gold, 3.46 g/t silver, 0.01% copper (4.46 g/t AuEQ) over 10.50 m

See Table 1 below for select drill results of hole GS-25-190 accompanied by a plan map and cross sections.

GS-25-190 was targeted to infill high-grade mineralization between 300N and 300H and provide continuity between the two previously unconnected zones. This drill hole expands the mineralized footprint of 300H by 70 m to the east and 300N by 45 m to the southwest. In addition, the intercepted mineralization occurs along a structural orientation similar to the previously identified four sub-parallel gold-bearing breccia systems of the SC-1 Zone. Mineralization along this axis now connects 300H and 300N.

Tudor has filed a permit application for the development of an underground ramp to access the high-grade gold SC-1 Zone as well as the other higher-grade gold zones. Once the ramp is completed, underground drill stations will be excavated to support definition drilling for mine-planning purposes and provide for more efficient expansion drilling. Underground drilling is expected to reduce the time and cost of delineating the high-grade gold zones and allow for year-round drilling by Tudor.

Remaining Drill Holes and Mineral Resource Update

The results from the remaining two drill holes from the 2025 Exploration Program will be released in the coming weeks. Following the receipt of the remaining drill hole data, an updated Mineral Resource estimate will be prepared that will include all drilling from 2024 and 2025 exploration programs comprising approximately 15,000 meters of drill data. The updated block model used to estimate the 2025 Mineral Resource will be comprised of 5mx5mx5m blocks rather than the 10mx10mx10m blocks used to estimate the 2024 Mineral Resource estimate. The smaller block size will provide better resolution of the higher-grade gold mineralization. The updated Mineral Resource estimate is targeted to be completed in the fourth quarter of this year.

Table 1: Select Drill Results for Drillhole GS-25-190

• All assay values are uncut and intervals reflect drilled intercept lengths.

• HQ and NQ diameter core samples were sawn in half and typically sampled at standard 1.5 m intervals.

• The following metal prices were used to calculate the Au Eq metal content: Gold $1850/oz, Ag: $21/oz, Cu: $3.75/lb. Calculations used the formula AuEQ = Au g/t + (Ag g/t*0.0100901) + (Cu ppm*0.0001236). All metals are reported in USD and calculations consider recoveries of 90 % for gold, 80 % for copper, and 80 % for silver.

• 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.

About Treaty Creek

The Treaty Creek Project hosts the Goldstorm Deposit, comprising a large gold-copper porphyry system, as well as several other mineralized zones. As disclosed in the "NI-43-101 Technical Report for the Treaty Creek Project", dated April 5, 2024 prepared by Garth Kirkham Geosystems and JDS Energy & Mining Inc., the Goldstorm Deposit has an Indicated Mineral Resource of 27.87 million ounces (Moz) of AuEQ grading 1.19 g/t AuEQ (21.66 Moz gold grading 0.92 g/t, 2.87 billion pounds (Blbs) copper grading 0.18%, 128.73 Moz silver grading 5.48 g/t) and an Inferred Mineral Resource of 6.03 Moz of AuEQ grading 1.25 g/t AuEQ (4.88 Moz gold grading 1.01 g/t, 503.2 Mlb copper grading 0.15%, 28.97 Moz silver grading 6.02 g/t), with a pit constrained cut-off of 0.7 g/t AuEQ and an underground cut-off of 0.75 g/t AuEQ. The Goldstorm Deposit remains open in all directions and requires further exploration drilling to determine the size and extent of the Deposit.
