Silver47 Completes Successful Red Mountain Drill Program and Intersects Massive Sulfides in Multiple Holes

The Red Mountain Deposit Remains Open to Expansion in Multiple Directions with Assays Pending

Silver47 Exploration Corp. (TSXV: AGA,OTC:AAGAF) (OTCQB: AAGAF) (‘Silver47’ or the ‘Company’) is pleased to announce the completion of its summer 2025 drill program at its wholly-owned Red Mountain Project in south-central Alaska.

Highlights:

• Significant Mineralization Intersected: Completed eight holes at Dry Creek and seven holes at West Tundra Flats, intersecting massive, semi-massive, and disseminated sulfides in step-out and infill drilling, with assays pending (see Figure 2-5 of core photos below).

• Establishing a Strong Alaskan High-Grade Resource Base: The 2025 program targeted untested areas near historical high-grade intercepts to enhance Red Mountain’s inferred 168.6 million silver equivalent ounce resource (336 g/t AgEq*) at Dry Creek and West Tundra Flats.

• Red Mountain Deposit Open to Expansion: Both the Dry Creek and West Tundra Flats zones remain open to expansion in multiple directions and the Company is completing detailed geological modelling to guide vectoring towards additional mineralization in 2026.

• Multiple Untested Targets: There are at least 35 mineralized prospects across the Red Mountain Project covering a 55 km trend many of which are undrilled or represent preliminary drilled discoveries.

• High-Value Critical Minerals: An ongoing metallurgical study is evaluating Red Mountain’s potentially significant concentrations of antimony and gallium, critical for U.S. defense, where current supply chains are at risk from foreign dominance.

• Fully Capitalized: The Company is fully funded with approximately $27 million in working capital to deploy towards aggressive growth-oriented drilling on our American silver projects.

Galen McNamara, CEO, stated: ‘The 2025 Red Mountain drill program has intersected massive sulfides in multiple holes. With assays pending, we now look forward to drilling at Mogollon in Q4 of this year and Hughes in early 2026. Fully funded with $27 million, we’re positioned to accelerate resource growth on our silver and critical mineral projects to deliver value from America’s next generation of strategic mineral assets.’

*Notes: g/t=grams per tonne; AgEq=silver equivalent; ZnEq=zinc equivalent; m=metres; Ag=silver; ‎Au=gold; Cu=copper; Zn=zinc; Pb=lead; 1ppm=1 g/t. Equivalencies are calculated using ratios with metal prices of US$2,750/tonne Zn, US$2,100/tonne Pb, US$8,880/tonne Cu, US$1,850/oz Au, and US$23/oz Ag and metal recoveries are based on metallurgical work returned of 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80% Au. Silver Equivalent (AgEq g/t) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (g/t) x 1] + [Au (g/t) x 91.93]

Drill Program

The 2025 Red Mountain drill program consisted of fifteen drill holes – eight holes at the Dry Creek target (Figure 1) and seven holes were completed at the West Tundra Flats target (Figure 1). The Dry Creek and West Tundra Flat targets together account for an inferred resource of 15.6 Mt at 336 g/t AgEq* for 168.6 million silver equivalent ounces.

Drilling at both targets consisted of a series of infill and step-out holes designed to test areas near historical high-grade drill intercepts and modelled domains where the structural controls on high-grade mineralization were not fully resolved. Multiple holes at each target intersected mineralized zones consisting of variable proportions of massive, semi-massive, and disseminated sulfides (Figures 2, 3, 4, and 5). Assays are pending from all holes drilled.

Based on observations from drilling together with results from ongoing geological modelling, multiple mineralized lenses and domains at Dry Creek and West Tundra Flats targets remain open along strike and down-dip. The company will integrate all new assay data with the geological modelling to guide vectoring towards additional VMS-related, high-grade mineralization in 2026.

Quality Assurance and Quality Control

Quality assurance and quality control (QAQC) protocols for drill core sampling at the Red Mountain Project followed industry standard practices. Core samples were typically taken at 1.0 m intervals in mineralized zones, and 3.0 m intervals outside of mineralized zones. Sample lengths were adjusted as necessary so as not to cross lithologic and mineralogic boundaries. QAQC check samples were inserted into the sample stream with one blank, one duplicate (coarse), and one certified reference material (CRM) occurring within every 20 samples. Drill core was cut in half, bagged, sealed and delivered directly to ALS Minerals Fairbanks, Alaska for transport to the ALS Minerals Laboratories labs in North Vancouver, British Columbia. ALS Minerals Laboratories are registered to ISO 9001:2008 and ISO 17025 accreditations for laboratory procedures. Core samples were analyzed at ALS Laboratory facilities in North Vancouver using four-acid digestion with an ICP-MS finish. Gold analysis was by fire assay with atomic absorption finish, or gravimetric finish for over-limit samples. Over-limits for silver, zinc, copper, and lead were analyzed using Ore Grade four-acid digestion. The standards, certified reference materials, were acquired from CDN Resource Laboratories Ltd. of Langley, British Columbia and selected to represent expected mineralization.
