AMERICAN CREEK'S JV PARTNER TUDOR GOLD COMMENCES 2025 EXPLORATION DRILL PROGRAM AT TREATY CREEK

American Creek Resources Ltd. project operator and joint venture partner Tudor Gold Corp. has provided an update on the 2025 exploration drill program at the flagship Treaty Creek project, located in the Golden Triangle of northwestern British Columbia.

2025 exploration program

Phase 1 drilling of the 2025 exploration program has commenced and is expected to consist of seven holes totalling approximately 6,000 metres of diamond drilling at the Goldstorm deposit. The primary objective of the phase 1 drill program is to expand the recently discovered high-grade gold Supercell-One system (SC-1), which was delineated over an 800-metre-by-400-metre area during 2024. SC-1 is a gold-dominant, quartz-sulphide, breccia-hosted structural corridor open to the northwest, north and east. There is excellent potential to discover further high-grade SC-1-style gold-bearing structures proximal to the Goldstorm deposit within a 600-metre-by-400-metre area extending from SC-1 to previously identified high-grade intercepts within the 300H and 300N domains of the Goldstorm deposit.

Drill results from SC-1 in 2022 to 2024 include the following high-grade gold intercepts:

• GS-23-176-W1: 15.00 metres at 15.64 grams per tonne gold equivalent (14.89 grams per tonne gold, 4.72 grams per tonne silver and 0.60 per cent copper);
• GS-22-134: 25.50 metres at 9.96 grams per tonne gold equivalent (9.66 grams per tonne gold, 1.23 grams per tonne silver and 0.24 per cent copper):
  • Including 4.50 metres at 20.86 grams per tonne gold equivalent (20.61 grams per tonne gold, 1.50 grams per tonne silver and 0.20 per cent copper);
• GS-23-179: 12.00 metres at 10.07 grams per tonne gold equivalent (9.78 grams per tonne gold, 1.35 grams per tonne silver and 0.23 per cent copper);
• GS-24-185: 13.50 metres at 9.60 grams per tonne gold equivalent (9.58 grams per tonne gold, 0.44 gram per tonne silver and 0.01 per cent copper).

Drill results from the 300H and 300N domains in 2021 and 2023 include the following high-grade gold intercepts:

• GS-21-113-W1: 13.50 metres at 8.96 grams per tonne gold equivalent (8.77 grams per tonne gold, 15.10 grams per tonne silver and 0.01 per cent copper);
• GS-21-113: 24.00 metres at 6.06 grams per tonne gold equivalent (5.81 grams per tonne gold, 20.30 grams per tonne silver and 0.01 per cent copper);
• GS-23-178-W1: 12.00 metres at 6.03 grams per tonne gold equivalent (5.90 grams per tonne gold, 12.31 grams per tonne silver and 0.01 per cent copper).

Phase 2 of the 2025 exploration program will consist of 1,600 metres of additional exploration drilling contingent on the success of phase 1 drilling.

Underground permitting

The application to permit an underground exploration drill program focused on the high-grade SC-1 is expected to be finalized in the coming weeks. Phase 3 of the 2025 exploration program will consist of two oriented-core geotechnical diamond drill holes, totalling approximately 500 metres, targeting the portal and ramp entrance area for the underground development. These holes are planned to be drilled at the end of the 2025 exploration program.

Ken Konkin, senior vice-president of exploration for Tudor Gold, commented: "We are focused on increasing the high-grade gold potential of SC-1 with this year's drill program. The planned holes are designed to expand upon the successful intercepts from our recent drill campaigns. The targets are structurally controlled, late-stage, gold-rich breccia systems that complement the four known SC-1 structures: SC-1 A, B, C and D. We look forward to a successful 2025 exploration program in the following months as we begin our quest to develop a multimillion-ounce high-grade gold system peripheral to the gold-copper Goldstorm deposit."

Quality assurance and control

Ken Konkin, PGeo, senior vice-president of exploration for Tudor Gold, is the qualified person, as defined by National Instrument 43-101, responsible for the project. Mr. Konkin has reviewed, verified and approved the scientific and technical information in this news release.

About Treaty Creek

The Treaty Creek project hosts the Goldstorm deposit, comprising a large gold-copper porphyry system, as well as several other mineralized zones. As disclosed in the "NI-43-101 Technical Report for the Treaty Creek Project," dated April 5, 2024, prepared by Garth Kirkham Geosystems and JDS Energy & Mining Inc., the Goldstorm deposit has an indicated mineral resource of 27.87 million ounces of gold equivalent grading 1.19 grams per tonne gold equivalent (21.66 million ounces gold grading 0.92 gram per tonne, 2.87 billion pounds copper grading 0.18 per cent and 128.73 million ounces silver grading 5.48 grams per tonne) and an inferred mineral resource of 6.03 million ounces of gold equivalent grading 1.25 grams per tonne gold equivalent (4.88 million ounces gold grading 1.01 grams per tonne, 503.2 million pounds copper grading 0.15 per cent and 28.97 million ounces silver grading 6.02 grams per tonne), with a pit-constrained cut-off of 0.7 gram per tonne gold equivalent and an underground cut-off of 0.75 gram per tonne gold equivalent.

The Goldstorm deposit has been categorized into three dominant mineral domains and several smaller mineral domains. The CS-600 domain largely consists of nested pulses of diorite intrusive stocks and hosts the majority of the copper mineralization within the Goldstorm deposit. CS-600 has an indicated mineral resource of 15.65 million ounces of gold equivalent grading 1.22 grams per tonne gold equivalent (9.99 million ounces gold grading 0.78 gram per tonne, 2.73 billion pounds copper grading 0.31 per cent and 73.47 million ounces silver grading 5.71 grams per tonne) and an inferred mineral resource of 2.86 million ounces of gold equivalent grading 1.20 grams per tonne gold equivalent (1.87 million ounces gold grading 0.79 gram per tonne, 475.6 million pounds copper grading 0.29 per cent and 13.4 million ounces silver grading 5.63 grams per tonne). The Goldstorm deposit remains open in all directions and requires further exploration drilling to determine the size and extent of the deposit.

Treaty Creek JV partnership

American Creek is a proud partner in the Treaty Creek project.

The project is a joint venture, with Tudor Gold owning three-fifths and acting as operator. American Creek and Teuton Resources each have a one-fifth interest in the project, creating a 3:1 ownership relationship between Tudor Gold and American Creek.

Tudor and American Creek entered into a binding letter of intent on June 6, 2025, and announced on June 9, 2025, pursuant to which Tudor will acquire all of the issued and outstanding shares of American Creek by way of a plan of arrangement. Currently, American Creek holds a 20-per-cent carried interest and Tudor holds a 60-per-cent interest in the Treaty Creek project, located in northwestern British Columbia. On completion of the proposed transaction, Tudor will hold an 80-per-cent interest in the Treaty Creek project.
