Metals Creek Samples 2.3% Antimony at Careless Cove in Newfoundland

Thunder Bay, Ontario--(Newsfile Corp. - November 4, 2025) - Metals Creek Resources Corp. (TSXV: MEK) (FSE: M1C1) (the "Company" or Metals Creek) is pleased to announce additional high-grade gold and antimony assay results from follow-up sampling at the Careless Cove Property in Newfoundland.

The Careless Cove Property is located within and adjacent to New Found Gold Corp.'s Queensway High-Grade Gold Project and approximately 12 kilometers southwest of New Found Gold's Keats Zone drilling (See Fig. 1: Careless Cove Location Map).

Recent follow-up prospecting and sampling took place in October to further evaluate recent high-grade assay results (See News Release: February 19, 2025) for gold and anomalous antimony. This prospecting program returned high-grade gold assays ranging from 0.07 to 10.54 grams per tonne (g/t) gold (Au) with associated high-grade antimony (Sb) assays (See Table 1: Assay Results) with values up to 2.3 percent (%). Previous sampling returned Sb values up to 0.27%. Mineralization is hosted within silicified sediments with vuggy quartz and with associated pyrite, arsenopyrite and stibnite. These assay results were from two clusters of samples (See Fig 2: Sample Location Map) from subcrop to rubble material 82m apart. The Sb is hosted within crosscutting veins (See Fig 2) with stibnite-arsenopyrite-quartz similar to other Sb mineralization located in close proximity to the Dog Bay Line, a northeast trending regional structure including the Beaver Brook Antimony Mine which is located 29 kilometers (km) to the southwest.

The high-grade Sb results is highly encouraging, showing a strong correlation between high-grade Au and Sb. Previous soil sampling programs highlighted this area to be prospective for pathfinder elements including Au and Sb. Several high-grade Au occurrences have not been sampled for Sb which will be taking place over the next several weeks.

Note: The surface grab samples described in this news release are selective by nature and are unlikely to represent average grades of the property.

Metals Creek has recently received approval for a trenching permit application to further evaluate mineralization within the Careless Cove Road Zone.

Analyses in this release was performed by Eastern Analytical of Springdale, NL with ISO 17025 accreditation. Samples were transported in sealed bags to Eastern and all samples were assayed using industry-standard assay techniques for gold. Gold was analyzed by a standard 30 gram fire assay with an AA finish. Over limits for Sb involves digesting within with HCL / Nitric acid and tartaric acid with an AA finish.
