Galen McNamara, Chief Executive Officer of Silver47, stated: "Silver47 now emerges as a premier United States-focused high-grade silver explorer and developer. Uniting projects in Alaska, Nevada, and New Mexico cumulatively hosting well over 200 million silver equivalent ounces with clear upside potential, we're poised to benefit from a renewed interest in United States mineral development at a time when the importance of domestic production has returned to the national spotlight. With a talented team, strong cash position, and support from our shareholders, we plan to aggressively drive exploration, growth, and development. This combination enhances our scale and visibility in an emerging silver and critical metals market, positioning us to advance our vision and deliver ongoing value to shareholders."
Following the Transaction, the Combined Company is a premier high-grade silver focused explorer and developer with a portfolio of silver-rich mineral resource staged projects in the United States (Alaska, Nevada and New Mexico). Collectively, the Companies' mineral resources equal approximately 10 Moz AgEq at 333 g/t AgEq of indicated mineral resources and 236 Moz AgEq at 334 g/t AgEq inferred mineral resources (see mineral resource table below for full details) with substantial upside and a shared vision for significant additional silver discovery and consolidation.
Under the terms of the Transaction, Summa shareholders received 0.452 common shares of Silver47 (each whole share, a "Silver47 Share") in exchange for each Summa common share (each a "Summa Share) held (the "Exchange Ratio").
As a result of the Transaction, Summa has become a wholly-owned subsidiary of Silver47 and the Summa Shares are anticipated to be delisted from the TSX Venture Exchange at market close on or about August 5, 2025. Following the delisting, Summa intends to apply to cease to be a reporting issuer under applicable Canadian securities laws.
Strategic Rationale for Transaction
- Creation of a Leading High-Grade US-Focused Silver Explorer and Developer: The combination of Silver47's Red Mountain project in Alaska with Summa's Hughes project in Nevada and Mogollon project in New Mexico establishes a premier portfolio of high-grade silver-focused assets in the United States enhancing the Combined Company's scale, leverage to silver and appeal to investors.
- Expanded Resource Base for Accelerated Growth: The Transaction consolidates significant mineral resources of approximately 10 Moz AgEq at 333 g/t AgEq of indicated mineral resources and 236 Moz AgEq at 334 g/t AgEq inferred mineral resources (see mineral resource table below for full details) with significant growth potential between the three United States-based projects positioning the combined company to accelerate exploration and development towards production.
- Significant Re-Rate Potential Based on Valuation of Peers: The Combined Company is currently undervalued on an EV/oz metric of US$0.33/oz AgEq for their pro forma current total MI&I resource endowment. The Combined Company has significant growth potential through re-rating relative to peers, through systematic exploration, resource growth, and strategic acquisitions.
- Enhanced Capital Markets Profile and Liquidity: By consolidating projects and increasing market capitalization, the Combined Company can be expected to benefit from improved visibility and access to capital, appealing to institutional investors seeking exposure to high grade U.S.-based silver projects, supported by a tight share structure with strong backing from investors including Eric Sprott.
- Continued Growth and Value Creation: The Combined Company will pursue organic and acquisitive growth to consolidate and create a high-quality silver portfolio in the U.S. The Combined Company will plan to (i) advance the current portfolio, creating strong silver development projects by expanding on resources and grade; and (ii) continue to consolidate the silver market, acquiring high-quality silver projects in tier 1 jurisdictions at accretive valuations.
- Exceptional Technical & Capital Markets Team, and Commitment to Shareholder Value Creation: The board of directors and management team of the Combined Company includes members with deep experience in the capital markets as well as proven mine finding and mine development histories.
Benefits to Silver47 and Summa Shareholders
- Shareholders of the Combined Company will have exposure to a diversified portfolio of high-grade United States silver projects, reducing risk while positioning for upside in a rising silver market.
- The Combined Company's enhanced scale will strengthen its ability to attract strategic partnerships, unlocking capital for exploration and development to drive share price appreciation.
- Shareholders of the Combined Company will benefit from a unified management team with complementary expertise, optimizing project execution at Red Mountain, Hughes, and Mogollon for efficient resource growth and development.
- The Transaction's all-share structure aligns long-term shareholder interests, ensuring shared commitment to advancing projects and pursuing value-accretive opportunities.
- An expected increase in market exposure from high-profile United States assets should enhance the Combined Company's appeal to global investors, supporting potential inclusion in silver-focused indices and ETFs.
- Shareholders of the Combined Company are expected to benefit from reduced G&A, cost savings, and prioritized work programs and asset catalysts to drive a potential re-rating for the Combined Company.

Notes to Silver47 Mineral Resources:
1. The 2024 Red Mountain mineral resource estimate ("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.
2. Mr. Warren Black, M.Sc., P.Geo. of APEX Geoscience Ltd., a "qualified person" ("QP") as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), is responsible for completing the MRE, effective January 12, 2024.
3. Mineral resources that are not mineral reserves have no 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.
4. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market, or other relevant factors.
5. The quantity and grade of reported inferred mineral resources is uncertain, and there has not been sufficient work to define the inferred mineral resource as an indicated or measured mineral resource.
6. All figures are rounded to reflect the relative accuracy of the estimates. Totals may not sum due to rounding. Reported grades are undiluted.
7. 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.
8. 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.
9. Recoveries are 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80% Au.
10. ZnEQ (%) = [Zn (%) x 1] + [Pb (%) x 0.6364] + [Cu (%) x 2.4889] + [Ag (ppm) x 0.0209] + [Au (ppm) x 1.923]
11. AgEQ (ppm) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (ppm) x 1] + [Au (ppm) x 91.93]
12. Open-pit resource economic assumptions are US$3/tonne for mining mineralized and waste material, US$19/tonne for processing, and 48° pit slopes.
13. Underground resource economic assumptions are US$50/tonne for mining mineralized and waste material and US$19/tonne for processing.
14. Open-pit resources comprise blocks constrained by the pit shell resulting from the pseudoflow optimization using the open-pit economic assumptions.
15. 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.
Notes to Summa Mineral Resources:
1. Silver Equivalent (AgEq) cut-off grade for the Hughes Project in situ Mineral Resources is based on a silver price of $25/oz, recovery of 90% Ag, and cost assumptions including: USD$88.2/t average mining cost for approximately 70% longhole stoping and 30% cut and fill mining, USD$36.3/t processing cost, USD$9.7/t G&A cost, USD$0.20/oz Ag refining cost for a total mining, processing and G&A cost of USD$134.2/tonne. A 3% royalty has also been applied to the cut-off grade determination.
2. Silver Equivalent (AgEq) cut-off grade for the Hughes Project tailings Mineral Resources is contained within an optimized pit and based on a silver price of $25/oz, recovery of 90% Ag, and cost assumptions including: USD$2.25/t mining cost, USD$21.0/t processing cost, USD$9/t G&A cost, USD$0.50/oz Ag refining cost for a total mining, processing and G&A cost of USD$33.34/tonne. A 3% royalty has also been applied to the cut-off grade determination.
3. Silver Equivalent (AgEq) cut-off grade for the Mogollon Project Mineral Resources is based on a silver price of $25/oz, recovery of 97% Ag, and cost assumptions including: USD$83/t mining cost for longhole stoping, USD$36.3/t processing cost, USD$9.7/t G&A cost, USD$0.20/oz Ag refining cost for a total mining, processing and G&A cost of USD$129/tonne A 3% royalty has also been applied to the cut-off grade determination.
4. AgEq is based on silver and gold prices of $25/oz and $2100/oz respectively, and recoveries for silver and gold of 90% and 97%, respectively for the Hughes Project, and 97% and 97%, respectively, for the Mogollon Project. AgEq Factor= (Ag Price / Au Price) x (Ag Rec / Au Rec); g AgEq/t = g Ag/t + (g Au/t / AgEq Factor).
5. Rounding as required by reporting guidelines may result in apparent discrepancies between tonnes, grade, and contained metal content.
6. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources estimated will be converted into mineral reserves. The quantity and grade of reported Inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred mineral resources as Indicated mineral resources. It is uncertain if further exploration will result in upgrading them to the Indicated mineral resources category.
7. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
8. There are no known environmental, permitting, legal, or other factors which could materially affect the MREs.

About Silver47
Silver47 Exploration Corp. is a Canadian-based exploration company that wholly-owns six silver and critical metals (polymetallic) exploration projects in Canada and the US. These projects include the Red Mountain Project in southcentral Alaska, a silver-gold-zinc-copper-lead-antimony-gallium VMS-SEDEX project. The Red Mountain Project hosts an inferred mineral resource estimate of 15.6 million tonnes at 7% ZnEq or 335.7 g/t AgEq, totaling 168.6 million ounces of silver equivalent, as reported in the NI 43-101 Technical Report dated January 12, 2024. Silver47 also owns a 100% interest in the Hughes Project located in central Nevada and the Mogollon Project located in southwestern New Mexico. The high-grade past-producing Belmont Mine, one of the most prolific silver producers in the United States between 1903 and 1929, is located on the Hughes Project. The Mogollon Project is the largest historic silver producer in New Mexico. Both projects have remained inactive since commercial production ceased and neither have seen modern exploration prior to Summa's involvement.
