AMERICAN CREEK'S JV PARTNER TUDOR GOLD ANNOUNCES POSITIVE RESULTS FROM INITIAL METALLURGICAL TESTING FOR THE HIGH-GRADE GOLD SUPERCELL-ONE COMPLEX WITHIN THE GOLDSTORM DEPOSIT, AT TREATY CREEK, LOCATED IN THE HEART OF THE GOLDEN TRIANGLE, BRITISH COLUMBIA

American Creek Resources Ltd. project operator and joint venture (JV) partner Tudor Gold has announced initial results from continuing metallurgical test work on the high-grade gold Supercell-One complex (SC-1), located at the Treaty Creek project, situated within the Golden Triangle of British Columbia. The initial metallurgical results of the SC-1 composites follow the highly successful initial metallurgical results of the CS-600 subdomain, which were released in the corporation's news release dated Oct. 25, 2024, and highlighted in this news release.

The SC-1 complex was discovered during the 2024 drill campaign. This discovery demonstrates significant additional economic potential for the Treaty Creek project. The SC-1 complex is peripheral to the CS-600 copper-gold domain and is best described as a series of subparallel, intermediate- to low-sulphidation breccia structures that overprint the Goldstorm gold-copper-silver porphyry deposit. The structures are superimposed over and cut through the CS-600 copper-gold domain as a late-stage event. The SC-1 complex comprises four distinct breccia structures: SC-1A, SC-1B, SC-1C and SC-1D. While SC-1B carries high-grade copper and silver mineralization, in addition to gold mineralization, it is the only structure that is considered polymetallic. The other three structures, SC-1A, SC-1C and SC-1D, are all high-grade gold systems.

Highlights from the results of the two lowermost structures, SC-1C and SC-1D, include:

• Flotation recoveries of up to 85.1 per cent gold were achieved.
• Flotation testing confirmed that a salable concentrate from the SC-1C and SC-1D auriferous quartz-pyrite breccia structures produced a concentrate grade of 33.6 grams per tonne (g/t) gold.

Results from the SC-1C and SC-1D structures complement the recently reported metallurgical testing on the lower CS-600 subdomain, which returned:

• Flotation recoveries within the lower CS-600 subdomain returned up to 88.1 per cent copper, 63.8 per cent gold and 51.3 per cent silver.
• Flotation testing confirmed that a high-grade copper concentrate with significant quantities of gold can be produced from the lower CS-600 subdomain that exceeds 29 per cent copper with significant gold and silver grades of 33 g/t and 96 g/t, respectively.

The samples reported in this news release are from the 2024 drill campaign and were selected from representative composite samples of the SC-1C and SC-1D structures.

Commenting on the results, Ken Konkin, president and chief executive officer of Tudor Gold, stated: "We are very pleased with our preliminary metallurgical test results for two of the SC-1 structures that we believe hold the greatest potential for making a substantial economic impact on the project. This marks a significant step forward in advancing the exploration and development of the high-grade-gold complex that may lead to the 'mine-within-a-mine concept' and represents a pivotal point generating a rejuvenation of a very significant exploration target that could require a much smaller capital cost as a starter area for the Treaty Creek project. SC-1C is the largest structure, spanning up to 800 metres in length by 400 metres in depth, that we believe can be effectively processed using standard metallurgical technology. All structures are open in all directions. Most importantly, these initial findings demonstrate that a viable gold concentrate could be generated from the largest breccia structures within the Supercell complex. Additionally, the original hole that intersected SC-1C (GS-22-134) contained 17 grains of fine-grained visible gold, observed over 4.5 metres, that averaged 20.61 g/t Au. Of importance to note was that the values in GS-22-134 had very consistent gold grades with no apparent 'nugget effect' that can often occur within these types of systems. Given that we see visible gold in the core, a gravity-flotation system is currently the best choice of beneficiation. However, Tudor's goal is to optimize and enhance recoveries, and to increase concentrate grades through flotation technology. Further metallurgical studies are also under way on the copper-gold-dominant CS-600 domain, for which initial metallurgical results were announced on Oct. 24, 2024. The metallurgical study showed that material extracted from the CS-600 copper-gold domain can be processed with conventional flotation techniques to produce a high-quality copper-gold concentrate. Looking forward, the focus in the near term is to continue to investigate the SC-1C and SC-1D mineralized horizons, given that these appear to have the best grade, width and continuity, to develop a multimillion-ounce complex analogous to that of the Valley of Kings deposit at Brucejack Lake. The company is working on permitting for an exploration ramp to best delineate the supercell structures and test for additional mineralized structures along that vast untested upper contact area of the CS-600 domain."

Initial test work reported in this news release was carried out on material from two structures (SC-1C and SC-1D) at the recently discovered SC-1 complex, which is within the Goldstorm deposit at the Treaty Creek project. Only fresh, non-oxidized, mineralized material was taken from SC-1D and SC-1C, and blended into a composite sample. Previously collected high-grade samples were not tested in the preliminary tests, ensuring that the test samples were not compromised by oxide minerals. The two supercell structures were blended as one composite and were subjected to mineralogy, gravity (Knelson/Mozley), whole ore cyanidation, whole ore pressure oxidation (POX) treatment, as well as batch and locked cycle flotation testing. Initial results demonstrated flotation as the most economical and simple method to recover gold and copper mineralization. Head assays of the two composites are listed in an attached table.

From the SC1-C and SC-1D composites, no gravity-recoverable gold was detected in these particular samples. A significant portion of gold (42 per cent) was found to be locked in sulphides. The cyanide leach at a primary grind of 75 microns recovered 46.8 per cent gold. Further test work at a finer grind is currently under way. Whole-ore POX performed well, yielding over 91 per cent gold extraction after 24 hours.

The use of flotation processes demonstrated very efficient gold recoverability, achieving impressive recovery rates of 91 to 93 per cent at the rougher stage with a primary grind of 75 microns. A coarser primary grind of 125 microns was also tested with no negative effects on the recovery. Locked cycle testing yielded 85 per cent overall recovery, producing a saleable concentrate with gold content of 33.6 g/t. This translates to a substantial five times increase in gold concentration with a 17-per-cent mass pull. However, the cleaner concentrate contains some deleterious elements such as 0.8 per cent arsenic, 0.3 per cent antimony, 0.005 per cent bismuth and 0.04 per cent mercury. It is suspected some of the deleterious elements are tied up in the tennanite/tetrahedrite minerals. Further flotation test work is currently under way to improve overall concentrate quality.

The metallurgical program was carried out by SGS, of Vancouver, B.C., which has been selected to conduct further mineralogical assessment of the Goldstorm sample material. The metallurgical and mineralogical work was conducted under the supervision of Travis O'Farrell, PEng, of Fuse Advisors, a qualified person as defined by National Instrument 43-101. Mr. O'Farrell has reviewed this news release and agreed to its contents.
