American Creek Resources Ltd. announced that project operator and JV partner Tudor Gold has provided the results of its updated Mineral Resource Estimate (MRE) prepared by Garth Kirkham P. Geo., of Kirkham Geosystems Ltd., and JDS Energy and Mining Inc. ("JDS") for the flagship Treaty Creek project (the "Project") located in the Golden Triangle Region of British Columbia. Tudor Gold's previous MRE for the Project was included in a technical report entitled "NI 43-101 Technical Report, Treaty Creek Project, British Columbia,", dated April 28, 2023, with an effective date of April 28, 2023. (the "2023 MRE").

Increased the Indicated Mineral Resource by 19% in gold equivalent ounces (AuEQ), consisting of a 16% increase in gold (Au), 14% increase in silver (Ag) and 32% increase in copper (Cu). Indicated Mineral Resource of 27.87 million ounces (Moz) of AuEQ within 730.20 million tonnes (Mt) at a grade of 1.19 g/t AuEQ; comprised of: 21.66 Moz of Au at 0.92 g/t, 128.73 Moz of Ag at 5.48 g/t, and 2.87 billion pounds (Blbs) of Cu at 0.18%. Inferred Mineral Resource of 6.03 Moz of AuEQ within 149.61 Mt at a grade of 1.25 g/t AuEQ; comprised of: 4.88 Moz of Au at 1.01 g/t, 28.97 Moz of Ag at 6.02 g/t, and 503.23 million pounds (Mlbs) of Cu at 0.15%.

The CS-600 domain, comprised of a monzodiorite intrusive stock and associated gold-copper porphyry system, constitutes a large part of the deposit with an Indicated Mineral Resource of 15.65 Moz of AuEQ within 400.29 Mt at a grade of 1.22 g/t AuEQ; consisting of: 9.99 Moz of Au at 0.78 g/t; and 2.73 Blbs of Cu at 0.31%. An 58% increase in the AuEQ ounces within the CS-600 domain. The 2023 drilling improved geologic understanding of the mineralization in the northern portion of the deposit.

The NS-STK Domain was reinterpreted to be a NE-SW trending stockwork and is associated with the 300H Domain mineralization. This system has now been separated into its own mineral domain, named 300N. Advanced metallurgical studies and refined the pit constrained and underground cutoff grades, increasing the pit constrained cutoff from 0.5 to 0.7 g/t AuEQ and the underground cutoff from 0.7 to 0.75 g/t AuEQ.

The 2023 Inferred Mineral Resource was 7.35 million ounces of AuEQ at 0.98 g/t AuEQ but the company was able to convert some of those ounces to the Indicated category and increase the grade of the current Inferred Mineral Resource of 6.03 million ounces of AuEQ to 1.25 g/t AuEQ. This was a result of drilling higher grades in step-out holes, as well as converting several of the 2023 Inferred Mineral Resources to the Indicated Mineral Resource category through closer-spaced fill-in drilling. Furthermore, the copper content of the CS-600 domain in the Indicated category has also increased by 37%, now containing 2.73 billion lbs of copper at 0.31% with an additional Inferred Mineral Resource of 476 million lbs of 0.29% copper.

The higher gold-equivalent grades in the Inferred category strongly suggests that the company has not yet passed through the strongest portion of the Goldstorm mineralized system.
