Vancouver, British Columbia--(Newsfile Corp. - May 12, 2026) - Tudor Gold Corp. (TSXV: TUD) (FSE: H56) (the "Company" or "Tudor") is pleased to report the positive results of its metallurgical program initiated in late 2025 with composite samples sourced from within and adjacent to the higher-grade Upper, Central, and Lower zones of Treaty Creek's Goldstorm Deposit. (See Figure 1 below for an oblique view of the Goldstorm Deposit zones.) Overall, the metallurgical test work demonstrates that saleable gold and copper concentrates can be produced from all three zones, either individually or as a blended feed. The results also indicate that mineralization from each zone can be mined and processed concurrently or in separate campaigns, providing flexibility in mine planning. A preliminary economic assessment on placing the Goldstorm Deposit in production is targeted for completion in the third quarter of this year.

Goldstorm Deposit Metallurgical Program Results

The metallurgical program primarily focused on producing a sulphide gold concentrate from the Upper and Lower Zones, while also evaluating the potential to produce both a copper concentrate and a sulphide gold concentrate from the Central Zone. In addition, to test whether mineralization from the three zones could be mined concurrently and processed as a combined mill feed, a blended composite was prepared using equal proportions from each of the three zone composites. This composite was tested to produce both a copper concentrate and a sulphide gold concentrate.

The Upper and Lower Zones both produced saleable sulphide concentrates, achieving excellent gold recoveries. The Upper Zone concentrate recovered 86% of the gold at a grade of 26.1 g/t gold and a mass pull of 11.8%. The Lower Zone recovered 87% of the gold at a grade of 19.0 g/t gold with a mass pull of 14%. The concentrates from both zones also contain potential silver credits and exhibit sulphur grades in excess of 45%, further enhancing their marketability.

The Central Zone produced two saleable concentrates. The copper concentrate recovered 55.1% of the gold at a grade of 68.9 g/t, 68.7% of the silver at a grade of 664.0 g/t, and 85.5% of the copper at a grade of 28.9% with a mass pull of 0.9%. The sulphide concentrate recovered 27.0% of the gold at a grade of 10.0 g/t, 20.0% of the silver at a grade of 57.0 g/t, and 8.6% of the copper at a grade of 0.9% at a mass pull of 3.1%. Combined recoveries from the Central Zone were 82.1% for gold, 88.7% for silver, and 94.1% for copper at a mass pull of 4.0%.

The blended composite, comprising mineralization from all three zones, produced two saleable concentrates. The copper concentrate recovered 22.9% of the gold at a grade of 159.1 g/t, 24.9% of the silver at a grade of 617.8 g/t, and 59.6% of the copper at a grade of 30.4% with a mass pull of 0.4%. The sulphide concentrate recovered 57.4% of the gold at a grade of 18.3 g/t, 56.7% of the silver at a grade of 64.5 g/t, and 29.5% of the copper at a grade of 0.7% with a mass pull of 9.4%. Combined recoveries for the blended composite were 80.3% for gold, 81.6% for silver, and 89.1% for copper at a mass pull of 9.8%. Minor optimization will be required to reduce copper losses to the sulphide concentrate.

The results of the locked-cycle test work are set out in Table 1 for the Upper, Central and Lower Zone composites and for the blended composite.

1. Upper Zone - Calculated head grade 3.57 g/t gold, 6.03 g/t silver, 0.06% copper
2. Central Zone - Calculated head grade 2.22 g/t gold, 17.2 g/t silver, 0.60% copper
3. Lower Zone - Calculated head grade 3.06 g/t gold, 11.06 g/t silver, 0.04% copper
4. Blended Zone - Calculated head grade 3.00 g/t gold, 10.69 g/t silver, 0.22% copper

Goldstorm Deposit Metallurgical Program

The metallurgical test work program was designed for initial flowsheet development for producing saleable concentrates from the three zones of the Goldstorm Deposit.

For the Upper and Lower Zones, the flowsheet selected for locked-cycle testing comprised a primary target grind to 120 µm, followed by conventional sulphide flotation. This included a regrind of the rougher concentrate and two stages of cleaner flotation.

For the Central Zone and the blended composite, the selected flowsheet likewise commenced with a primary target grind to 120 µm, followed by an initial copper flotation stage. The resulting rougher copper concentrate was reground and treated through three stages of cleaner flotation. The copper flotation tailings were subsequently processed through a sulphide rougher stage, after which the rougher concentrate was reground and subjected to three stages of cleaner flotation.

Variability test work is underway to test the flowsheet on specific drill hole samples that were used to make up the composites for each of the zones. If required, additional blended composites will be tested based on the annual production schedule developed for the Preliminary Economic assessment.

Preliminary Economic Assessment

Fuse Advisors Inc. of Vancouver, British Columbia, is continuing to advance the preliminary economic assessment on placing the Goldstorm Deposit at Treaty Creek in production, which is targeted for completion in the third quarter of this year.

The Goldstorm Deposit remains open in all directions, and a permit application has been filed for approval to construct an underground ramp for access to drill the high-grade gold SC-1 Zone. A Preliminary Economic Assessment on placing the Goldstorm Deposit in production as an underground mine is now underway.

In addition to the Goldstorm Deposit, Treaty Creek hosts other recent gold discoveries nearby: the CBS, Eureka and Perfectstorm zones. A 10,000-meter plus drill program is planned to commence in May targeting the further exploration of these zones.
