Tudor Gold Reports Positive Metallurgical Test Results for Treaty Creek's Goldstorm Deposit

• Metallurgical test work demonstrates that saleable gold and copper concentrates can be produced from all three zones of the Goldstorm Deposit - the Upper, Central, and Lower zones - either individually or as a blended feed.
• The Upper Zone recovered 86% of the gold at a grade of 26.1 grams per tonne gold, and the Lower Zone recovered 87% of the gold at a grade of 19 grams per tonne gold; both concentrates contain potential silver credits and sulphur grades in excess of 45%.
• Combined recoveries from the Central Zone were 82.1% for gold, 88.7% for silver, and 94.1% for copper across two saleable concentrates at a combined mass pull of 4%.
• The blended composite produced combined recoveries of 80.3% for gold, 81.6% for silver, and 89.1% for copper at a mass pull of 9.8%, with minor optimisation required to reduce copper losses to the sulphide concentrate.
• The results indicate that mineralisation from each zone can be mined and processed concurrently or in separate campaigns, providing flexibility in mine planning, with the preliminary economic assessment (PEA) targeted for completion in the third quarter of this year.

Goldstorm Deposit at Treaty Creek

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, 912.3 million tonnes grading .85 grams per tonne gold, 5.07 grams per tonne silver, and .15% 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, 21.8 million tonnes grading 3.64 grams per tonne gold, 10.22 grams per tonne silver, and .14% copper. The Goldstorm Deposit remains open in all directions, and a permit application has been filed for approval to construct an underground ramp to access the high-grade gold SC-1 Zone. A preliminary economic assessment (PEA) 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-metre-plus drill program is planned to commence in May, targeting the further exploration of these zones.

Metallurgical Program Overview

Tudor Gold Corp. has reported 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. 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 mineralisation from each zone can be mined and processed concurrently or in separate campaigns, providing flexibility in mine planning.

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. To test whether mineralisation from the three zones could be mined concurrently and processed as a combined mill feed, a blended composite was prepared using equal proportions of each of the three zone composites and tested to produce both a copper concentrate and a sulphide gold concentrate.

Upper and Lower Zone Results

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 grams per tonne gold and a mass pull of 11.8%. The Lower Zone recovered 87% of the gold at a grade of 19 grams per tonne gold with a mass pull of 14%. The concentrates from both zones also contain potential silver credits and exhibit sulphur grades exceeding 45%, further enhancing their marketability.

Central Zone Results

The Central Zone produced two saleable concentrates. The copper concentrate recovered 55.1% of the gold at a grade of 68.9 grams per tonne, 68.7% of the silver at a grade of 664 grams per tonne, and 85.5% of the copper at a grade of 28.9% with a mass pull of .9%. The sulphide concentrate recovered 27% of the gold at a grade of 10 grams per tonne, 20% of the silver at a grade of 57 grams per tonne, and 8.6% of the copper at a grade of .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%.

Blended Composite Results

The blended composite, comprising mineralisation from all three zones, produced two saleable concentrates. The copper concentrate recovered 22.9% of the gold at a grade of 159.1 grams per tonne, 24.9% of the silver at a grade of 617.8 grams per tonne, and 59.6% of the copper at a grade of 30.4% with a mass pull of .4%. The sulphide concentrate recovered 57.4% of the gold at a grade of 18.3 grams per tonne, 56.7% of the silver at a grade of 64.5 grams per tonne, and 29.5% of the copper at a grade of .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 optimisation will be required to reduce copper losses to the sulphide concentrate.

Metallurgical Flowsheet

For the Upper and Lower zones, the flowsheet selected for locked-cycle testing comprised a primary target grind to 120 micrometres, followed by conventional sulphide flotation, including 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 micrometres, 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 testing is underway to evaluate the flowsheet using specific drill-hole samples that make up the composites for each zone. If required, additional blended composites will be tested in accordance with the annual production schedule developed for the PEA. Fuse Advisors Inc. of Vancouver, British Columbia, is continuing to advance the PEA to place the Goldstorm Deposit at Treaty Creek into production, with completion targeted for the third quarter of this year.

Next Steps

Variability test work is underway on the flowsheet across specific drill hole samples from each zone. Additional blended composites will be tested if required based on the annual production schedule developed for the PEA. The PEA on placing the Goldstorm Deposit in production is targeted for completion in the third quarter of this year. A 10,000-metre-plus drill program is planned to commence in May, targeting the further exploration of the CBS, Eureka, and Perfectstorm zones at Treaty Creek.
