Tudor Gold Reports Positive Metallurgical Test Results for Treaty Creek
Rhea-AI Summary
Tudor Gold (OTCQB:TDRRF) reported positive metallurgical test results from the Upper, Central and Lower zones of the Goldstorm Deposit at Treaty Creek. Locked-cycle tests show saleable gold and copper concentrates can be produced from each zone and from a blended feed.
Combined recoveries reached 80.3% gold, 81.6% silver and 89.1% copper for the blended composite. The results indicate zones can be mined and processed separately or together, supporting flexible mine planning. A preliminary economic assessment on putting Goldstorm into production is targeted for completion in the third quarter of this year.
Positive
- Upper Zone gold concentrate recovered 86% of gold at 26.1 g/t with 11.8% mass pull
- Lower Zone gold concentrate recovered 87% of gold at 19.0 g/t with 14% mass pull
- Central Zone combined concentrates recovered 82.1% gold, 88.7% silver and 94.1% copper at 4.0% mass pull
- Blended composite combined concentrates recovered 80.3% gold, 81.6% silver and 89.1% copper at 9.8% mass pull
- All three zones and blended feed produced saleable gold and copper concentrates, enabling flexible mine planning
- Preliminary economic assessment for placing the Goldstorm Deposit in production is targeted for completion in Q3 this year
Negative
- Minor optimization is required to reduce copper losses to the sulphide concentrate in the blended composite
- Preliminary economic assessment on placing the Goldstorm Deposit in production is still in progress and not yet completed

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
The Central Zone produced two saleable concentrates. The copper concentrate recovered
The blended composite, comprising mineralization from all three zones, produced two saleable concentrates. The copper concentrate recovered
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.

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.
