Tudor Gold Intersects 1.70 g/t Gold over 46.00 Meters at Treaty Creek

Rhea-AI Summary

Tudor Gold (symbol: TDRRF) reported results from drill hole GS-25-191 at the 80%-owned Treaty Creek Project on October 16, 2025. The hole returned 1.70 g/t Au, 12.56 g/t Ag, 0.02% Cu (1.85 g/t AuEQ) over 46.00 m, including 4.12 g/t Au over 8.90 m and 1.91 g/t Au over 7.40 m. The intercept links the 300 North and 300 Horizon zones along an SC-1 structural corridor now outlined ~350 m by 150 m. GS-25-191 expanded the 300N footprint by 55 m southwest and 300H by 110 m northeast. Assays are uncut; true widths remain undetermined and further drilling and a forthcoming Mineral Resource update (with sensitivity above 2 g/t Au) are planned.

Positive

• 46.00 m at 1.70 g/t Au (1.85 g/t AuEQ) in GS-25-191
• Includes 8.90 m at 4.12 g/t Au
• 300N–300H corridor now mapped ~350 m x 150 m
• 300N expanded 55 m and 300H expanded 110 m
• Planned Mineral Resource update with 2 g/t Au sensitivity

Negative

• All assay values are uncut, which can overstate reported grades versus capped results
• True widths have not been determined; orientation of mineralized body remains open
• Further drilling required; remaining 2025 hole results pending

Vancouver, British Columbia--(Newsfile Corp. - October 16, 2025) - Tudor Gold Corp. (TSXV: TUD) (FSE: H56) (the "Company" or "Tudor") is pleased to announce the results of the fourth 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-25-191 intersected a southwestward extension of the 300 North Zone ("300N"), linking mineralized intercepts within the 300N and 300 Horizon Zone ("300H") along a potential SC-1 Zone structural corridor, now extending approximately 350 m by 150 m. Highlights of the mineralized intercept:

• 1.70 g/t gold, 12.56 g/t silver and 0.02% copper (1.85 g/t gold equivalent ("AuEQ")) over 46.00 m, including:

  • 4.12 g/t gold, 16.48 g/t silver and 0.01% copper (4.30 g/t AuEQ) over 8.90 m, and:

  • 1.91 g/t gold, 25.06 g/t silver and 0.01% copper(2.17 g/t AuEQ) over 7.40 m.

See Table 1 below for select drill results of hole GS-25-191 accompanied by a plan map and cross section.

GS-25-191 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 300N by 55 m to the southwest and 300H by 110 m to the northeast. 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 provides additional pierce points connecting 300H and 300N Zones.

Drilling continues to confirm the higher-grade gold structures within the bulk-tonnage Mineral Resource at Treaty Creek. The upcoming Mineral Resource estimate for Treaty Creek will, in addition to updating the overall Mineral Resource, also provide sensitivity analysis of the tonnes and grade above 2 g/t gold. This analysis will provide Tudor with the ability to assess the potential for a higher-grade underground mine with a smaller footprint to kickstart gold production.

Remaining Drill Hole

The results from the remaining drill hole from the 2025 Exploration Program will be released in the coming weeks.

Table 1: Select Drill Results for Drillhole GS-25-191

Hole	Collar Coords	Dip/ Azimuth	From (m)	To (m)	Interval (m)	Gold (g/t)	Silver (g/t)	Copper (%)	AuEQ(3) (g/t)
GS-25-191	428884 mE 6273677 mN	-64/245	776.50	822.50	46.00	1.70	12.56	0.02	1.85
		including	782.00	790.90	8.90	4.12	16.48	0.01	4.30
		and	812.10	819.50	7.40	1.91	25.06	0.01	2.17
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.
