Silver47 Discovers New High-Grade Massive Sulfide Zone at Red Mountain Project, AlaskaProperty-Wide Prospecting Identifies Multiple Undrilled Silver-Rich Polymetallic Targets Across 60 km TrendVancouver, British Columbia--(Newsfile Corp. - December 30, 2025) - Silver47 Exploration Corp. (TSXV: AGA) (OTCQX: AAGAF) ("Silver47" or the "Company") is pleased to report results from a property-wide prospecting and rock sampling program from its wholly owned Red Mountain Project located in Alaska (the "Red Mountain Project"). The rock sampling program covered a widely dispersed 60 km trend and identified multiple new and undrilled silver-rich, polymetallic occurrences.Highlights:New High-Grade Massive Sulfide Discovery: The newly identified FOMO Zone exposes undrilled massive sulfide lenses up to 5 m wide at surface in areas previously considered unmineralized - potentially representing the surface expression of a new VMS system at the Red Mountain Project.Exceptional Surface Grades from the FOMO Zone: Grab samples from semi-massive to massive sulfides returned: 1,793 g/t AgEq* (23.2% Zn, 10.05% Pb, 2.54% Cu, 74 g/t Ag)1,138 g/t AgEq* (9.27% Zn, 11.65% Pb, 2.40% Cu, 54 g/t Ag)972 g/t AgEq* (8.5% Zn, 7.72% Pb, 2.51% Cu, 31 g/t Ag)District-Scale Discovery Potential: Property-wide prospecting identified multiple additional undrilled high-grade polymetallic occurrences with semi-massive to massive sulfides at surface, confirming widespread mineralization across the >60 km prospective trend.Multiple Targets Emerging: Integration of new rock sample results with historic data has defined a robust pipeline of priority, largely undrilled targets for first-pass drilling.Aggressive 2026 Drill Program Planned: Silver47 is fully funded and is preparing a significant summer drill campaign to test both the existing resource areas and these exciting new high-priority exploration targets at the Red Mountain Project.Continuous Drilling Across U.S. Silver Portfolio: Drilling is set to commence in January at the Mogollon Project (New Mexico) followed by Hughes (Nevada) starting March- providing steady news flow and resource expansion across the portfolio ahead of the summer program at Red Mountain, Alaska.*Notes: g/t = grams per tonne; 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]Galen McNamara, CEO, stated: "The discovery of the FOMO Zone - a new, undrilled massive sulfide occurrence in previously untested stratigraphy - along with multiple high-grade surface showings across the 60 km trend, further highlights the Red Mountain Project's potential to host a cluster of world-class VMS deposits. This property-wide prospecting program has delivered a robust pipeline of priority drill targets, while our 2025 drilling has provided key data for an ongoing mineral resource update. With aggressive 2026 programs planned across our three core U.S. projects, Silver47 is well positioned for multiple near-term catalysts and a potentially transformative year ahead."Gary Thompson, Executive Chairman, stated: "I'd like to take this opportunity to provide a summary of the past year and some insight into the ensuing year. Silver47 recently celebrated its one-year anniversary as a public company. This past year has been transformative for the Company with the at market merger of Summa Silver, where two $40 million market-cap companies formed a $202 million company today. Drilling and non-drilling success at Red Mountain, Adams Plateau and Kennedy continue to demonstrate the high-grade silver and gold potential of these assets. As we look to 2026 resource growth and advanced development it is top of mind. Some milestones for 2026 are as follows; an updated resource at Red Mountain potentially leading into PEA level study; resource growth at Mogollon and Hughes through continued drilling; advance studies on the recovery of silver-gold from tailings at Hughes; further M&A to accelerate our mission of becoming a 1 billion ounce of silver company. Lastly, I'd like to thank our shareholders for their support. With silver price action in our sails, we are looking forward to another stellar year."Figure 1.
