SUMMA SILVER ANNOUNCES STAKING OF THE HIGH-GRADE GOLD-SILVER KENNEDY PROJECT, NEVADA

Summa Silver Corp. has acquired the Kennedy project, located in Pershing county, Nevada, through low-cost claim staking. The Kennedy project consists of 99 mineral claims spanning approximately 2,000 acres, is 100 per cent owned by the company and is free of any royalties.

Key highlights:

• Past-producing district: The project covers most of the historic Kennedy mining district in northern-central Nevada where minor amounts of gold and silver were produced intermittently from high-grade veins between 1891 and the second World War.
• High grades reported: Historic mining focused on near-surface oxide mineralization where mined grades were reported to be 15 grams per tonne gold and 311 grams per tonne silver. Deeper secondary and sulphide mineralization reportedly remains unmined.
• Undrilled Nevada vein field: Approximately 22 kilometres of veins have been traced across the Kennedy project; these veins have not seen systematic modern exploration.
• Acquisition thesis: The Kennedy project represents an internally generated prospect that was acquired because it was open for staking and potentially represents a one-million-ounce near-surface gold target in Nevada.
• Company to remain focused on robust core projects: Summa Silver will continue to focus on the Hughes and Mogollon projects, where high-grade mineral resource estimates were recently announced.
• Hughes project drilling update: The previously announced drill program at the Hughes project is well under way. All holes completed have intersected zones of quartz veins, stockworks and breccias in aggressive stepouts at the Ruby zone. All assays are pending.

Galen McNamara, chief executive officer, stated: "It's not often that a significantly underexplored high-grade historic mining district in Nevada is open for staking. As many explorers in the state know, multiple important Nevada discoveries have been made by re-evaluating historic mining districts like this. Although we will continue to direct our focus to the Hughes and Mogollon projects, we look forward to advancing the Kennedy project to drill-ready status in the coming months."

Kennedy project summary

The Kennedy project consists of 99 unpatented mining claims located in Pershing county, Nevada, approximately 75 kilometres south of Winnemucca. The Kennedy project is situated on major aeromagnetic and gravity lineaments, which are also spatially associated with the Sleeper gold deposit. Priority exploration targets at the project consist of high-grade sheeted veins as well as bulk-tonnage disseminated and/or stockwork-hosted gold-silver mineralization.

The Kennedy district consists of numerous high-grade, gold-silver-bearing quartz veins, where over 22 kilometres of veins have been traced at surface. Most of historic mining in the Kennedy district was reportedly from the Gold Note mine, which was centered on a series of high-angle northwest-striking veins traced for over 350 metres along strike. Historic mining at Gold Note focused on near-surface (less than 40 metres) oxide mineralization. Deeper secondary sulphide mineralization remains unmined. Mine grades were reportedly as high as 15.5 grams per tonne gold with 311 grams per tonne silver.

Exploration plans

Following staking, a short prospecting and sampling program was completed and results are pending. The company is now planning a multidisciplinary exploration program consisting of geological mapping, soil geochemical sampling and IP (induced polarization) geophysics. Data from these programs will be used to prioritize targets for follow-up drill testing in early 2026.

Corporate update

In addition, the company has engaged the services of ICP Securities Inc. to provide automated market-making services, including use of its proprietary algorithm, ICP Premium, in compliance with the policies and guidelines of the TSX Venture Exchange and other applicable legislation.

ICP is an arm's-length party to the company.

The company has also engaged Fairfax Partners Inc. to provide investor relations services. Under the agreement, which starts immediately, Fairfax will receive a total payment of $70,000 plus GST (goods and services tax) for a three-month term.

About Summa Silver Corp.

Summa Silver is a junior mineral exploration company. The company owns a 100-per-cent interest in the Hughes project, located in central Nevada, and in 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 has seen modern exploration prior to the company's involvement.
