Yellow Fox Antimony Project Update

Thunder Bay, Ontario--(Newsfile Corp. - May 1, 2025) - Metals Creek Resources Corp. (TSXV: MEK) (FSE: M1C1) (the "Company" or Metals Creek), is pleased to announce that the Company has been advised by its option partner Lomiko Metals Inc. (TSXV: LMR) (Lomiko) of an update on the Yellow Fox, antimony, silver, and gold property acquired from Metals Creek as per news release issued on March 11^th, 2025 (https://lomiko.com/2025-news/lomiko-announces-work-program-on-yellow-fox-antimony-silver-and-gold-property-located-in-central-newfoundland-for-spring-2025/).

This property is on the same trend as the past-producing Beaver Brook antimony mine, which is located 25km southwest of the property. Yellow Fox is an early-stage exploration property prospective in antimony, gold, and silver where historic works returned samples anomalous in gold (Au), antimony (Sb), lead (Pb), zinc (Zn), and silver (Ag). Trenching exposed the rocks, resulting in grab samples to 59.43g/t Au, 11.10% Sb, 7.00% Zn, 72.90g/t Ag, and 5.50% Pb in arsenopyrite-stibnite veins within altered monzogranite. (See Metals Creek assessment report at https://gis.geosurv.gov.nl.ca/geofilePDFS/Batch2016/002D_0779.pdf)

Lomiko announces the expansion of the Yellow Fox's land package with a new claim block (039252M) for Yellow Fox, consisting of an additional 30 claims for a total of 748 hectares. Therefore, the entire property now consists of 58 claims for a total of 1,446 hectares. Lomiko looks forward to the completion of a targeted soil sampling field program, Phase 1. The plan is to complete 10 lines at 250 meters spacing and collect approximately 700 soil samples to better define existing highly prospective antimony, silver, and gold targets and further evaluate the area to the south of the Yellow Fox showing, where little to no work has been performed historically. Metals Creek will manage and complete the work program for Lomiko.

Yellow Fox antimony and gold prospect Spring 2025 Work Program

The Company reviewed existing data and devised a plan for the fieldwork program in the spring of 2025.

Phase 1 of the plan in the spring is focused on soil sampling with the following highlights:

• Soil sampling program targeted south of Yellow Fox, showing 59.413 g/t gold and areas of increased density of interpreted structures, See Figure 1.
• Approximately 700 soil samples on ten 250m spaced lines trending approximately 110 degrees with samples taken every 25m along the line.
• Should the soil sampling program be proven effective, expansion of the lines and additional lines to the south are warranted, which would be the focus of the Phase 2 program.
• Phase 2 will see the soil sampling completed on the 250-meter parallel grids at 25-meter spacing covering the southern end of the property.
• Phase 2 will also focus on ground truthing existing targets as well as following up on newly generated targets
• Depending on the results of the phase 1 testing, a targeted EM survey will be undertaken.

Please note that the results on an adjacent or nearby property (Beaver Brook) are not necessarily what can be expected on the Yellow Fox project and that the results of surface or grab samples, by their nature, this type of sample is selective and that the assay results may not be indicative of underlying mineralization.

Location Details

The Yellow Fox Property is located approximately 10 km southwest of the Town of Glenwood NL, and south of the Trans-Canada Highway. The Property occurs within NTS map sheets 02D/14 and 15 with excellent access along several logging and skidder roads originating from Glenwood. The main Yellow Fox showing is located in the central part of License 027536M, 5km from the western end of Gander Lake. The property is centred at approximately UTM (NAD 27) grid coordinates 5,419,400m North and 645,300m East.

Geologically, Yellow Fox exhibits similar traits to those of Beaver Brook with cross-cutting structural zones which show intense carbonate alteration with sulphide-bearing stringers to veins of stibnite and arsenopyrite with similar high-grade tenors of antimony, gold, lead, zinc, and silver. Arsenopyrite is also present in both locations. Two prominent fracture vein sets are present, one being the muscovite-pyrite-rutile veins trending 356 degrees and the second stibnite-quartz-arsenopyrite being the most abundant and trending 025 degrees. Both these vein sets are similar to that of the past producing Beaver Brook antimony Mine, and both vein sets trend in N to NE, which is the same as the prospective regional structures.
