Highlights
Drilling Commences at Red Mountain: A core drilling rig is now fully operational at the Red Mountain project in Alaska, actively advancing the first hole of Silver47's 2025 summer exploration program.
Targeting High-Impact Resource Growth: The program focuses on expanding the inferred 168.6 million silver equivalent ounce resource (336 g/t AgEq*) at Dry Creek and West Tundra Flats (see Table 1), where previous drilling by Silver47 and prior operators indicates significant expansion potential.
High-Grade Precious Metals Potential: The 2025 program targets untested areas near historical high-grade intercepts, prioritizing areas richer in silver and gold to enhance Red Mountain's resource base.
Strategic Critical Minerals Focus: Red Mountain hosts five critical minerals scarce in the U.S., including zinc, copper, tin, antimony and gallium, which will be evaluated during this program to support domestic supply chain security.
Upsized Program on the Horizon: Closing of Summa Silver's oversubscribed $6.9 million subscription receipt financing was completed on June 17th, paving the way for a substantial expansion of the current drilling campaign when the Silver47 and Summa Silver merger is complete.
Gary Thompson, CEO of Silver47, stated: "We are excited to kick off a significant drill program at our Red Mountain silver-gold-rich VMS project with a view to expanding the resource base and making new discoveries. The results from previous drill holes, including DC24-106, WT24-33 and DC18-77, demonstrate the robust nature of the Bonnifield district, where Red Mountain is located, and we are eager to build on these successes. This year is shaping up to be transformational for the Company with a full season of drilling and the pending merger with Summa Silver."
Highlights from Previous Drilling (see news releases dated November 21 and 26, 2024 and February 12, 2025):

*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]

- The 2024 Red Mountain MRE was estimated and classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines" dated November 29, 2019, and the CIM "Definition Standards for Mineral Resources and Mineral Reserves" dated May 10, 2014.
- Mr. Warren Black, M.Sc., P.Geo. of APEX Geoscience Ltd., a QP as defined by NI 43-101, is responsible for completing the 2024 Mineral Resource Estimate, effective January 12, 2024.
- Mineral resources that are not mineral reserves have not demonstrated economic viability. No mineral reserves have been calculated for Red Mountain. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future.
- The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market, or other relevant factors.
- The quantity and grade of reported Inferred Resources is uncertain, and there has not been sufficient work to define the Inferred Mineral Resource as an Indicated or Measured Mineral Resource. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- All figures are rounded to reflect the relative accuracy of the estimates. Totals may not sum due to rounding. Reported grades are undiluted.
- A standard density of 2.94 g/cm³ is assumed for mineralized material and waste rock. Overburden density is set at 1.8 g/cm³. For mineralized material blocks with iron assays close enough to estimate an iron value for the block, density is calculated using the formula: density (g/cm³) = 0.0553 * Fe (%) + 2.5426.
- Metal prices are 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.
- Recoveries are 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80% Au.
- ZnEQ (%) = [Zn (%) x 1] + [Pb (%) x 0.6364] + [Cu (%) x 2.4889] + [Ag (ppm) x 0.0209] + [Au (ppm) x 0.1923]
- AgEQ (ppm) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (ppm) x 1] + [Au (ppm) x 91.93]
- Open-pit resource economic assumptions are US$3/tonne for mining mineralized and waste material, US$19/tonne for processing, and 48° pit slopes.
- Underground resource economic assumptions are US$50/tonne for mining mineralized and waste material and US$19/tonne for processing.
- Open-pit resources comprise blocks constrained by the pit shell resulting from the pseudoflow optimization using the open-pit economic assumptions.
- Underground resources comprise blocks below the open-pit shell that form minable shapes. They must be contained in domains of a minimum width of 1.5 m at Dry Creek or 3 m height at West Tundra Flats. Resources not meeting these size criteria are included if, once diluted to the required size, maintain a grade above the cutoff.
- Global AgEq calculated using component metal grades: 3.41% Zn, 1.39% Pb, 0.17% Cu, 71.4 g/t Ag, 0.43 g/t Au.
Red Mountain Project Overview
Red Mountain, situated in south-central Alaska, is a high-grade volcanogenic massive sulfide (VMS) deposit wholly owned by Silver47 Exploration Corp. Hosted within the Devonian to Mississippian-aged Totatlanika Schist, the deposit comprises submarine volcanic and volcaniclastic rocks, primarily felsic to intermediate tuffs and flows, ideal for VMS mineralization. The project hosts an inferred resource of 168.6 million silver equivalent ounces at 336 g/t AgEq across the Dry Creek and West Tundra Flats deposits, with high-grade silver, gold, zinc, lead, and copper as reported in the NI 43-101 Technical Report dated January 12, 2024. Of particular importance, both Dry Creek and West Tundra Flats remain open to expansion. Beyond precious and base metals, Red Mountain contains critical minerals-antimony, gallium, zinc, copper, and tin-scarce in the U.S., supporting national supply chain security goals.
The broader Red Mountain property, spanning over 630 square kilometers, remains substantially underexplored. Airborne magnetic and electromagnetic surveys have identified multiple untested targets within the Totatlanika Schist's favorable stratigraphy. These targets, coupled with coincident high-grade mineralized rock samples and anomalous soil geochemistry, suggest strong potential for discovering additional VMS and sedimentary exhalative deposits across the property, positioning Red Mountain as a district-scale opportunity.
