Teuton Resources Reports Positive Metallurgical Results from Treaty Creek Project

Victoria, British Columbia — May 13, 2026 — Leads & Copy — Teuton Resources Corp. reports that Joint Venture partner Tudor Gold Corp. has announced positive results from its metallurgical program at the Treaty Creek’s Goldstorm Deposit.

The metallurgical program, initiated in late 2025, used composite samples from the higher-grade Upper, Central, and Lower zones of the Goldstorm Deposit. Test work demonstrates that saleable gold and copper concentrates can be produced from all three zones, either individually or as a blended feed.

Tudor’s May 12, 2026, news release indicated 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.

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

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 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 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.

Fuse Advisors Inc. is advancing the preliminary economic assessment on placing the Goldstorm Deposit at Treaty Creek in production, targeted for completion in the third quarter of this year.

Teuton was the original staker of the Treaty Creek property and presently holds a 20% carried interest in the Treaty Creek Project. Additionally, Teuton owns a 0.98% Net Smelter Royalty in the Goldstorm deposit area as well as in the northern portion of the Perfectstorm zone.

Teuton owns interests in more than twenty properties in the “Golden Triangle” area of northwest British Columbia and was one of the first companies to adopt the “prospect generator” model.
