Southern Silver Exploration Corp. (TSX-V: SSV) is pleased to report it has reached an agreement to acquire the Puro Corazon mining claim located contiguous to its 100%-owned Cerro Las Minitas project (see Figures 1 and 2 below) from an arms-length third-party.

The Puro Corazon mine, which is operated privately, is currently mining approximately sixty tonnes of ore per day and produces a silver-lead concentrate and a zinc concentrate. Southern Silver will be incorporating Puro Corazon into the much larger Cerro Las Minitas project to unlock significant capital and operating synergies. Southern Silver intends to immediately commence a 12,000-meter infill drilling program at Puro Corazon and then in the first quarter of 2026, commence preparation of an updated Technical Report and Preliminary Economic Assessment (“PEA”) in accordance with the provisions of National Instrument 43-101.

Key Transaction Highlights

• Strong Potential for Near-term Resource Growth: infill drilling program to support incremental resource additions for the consolidated Cerro Las Minitas project.
• Capital Efficiency Gains: opportunity to improve capital efficiency through faster access to higher value mineralization, while avoiding development around the Puro Corazon mining claim.
• Enhanced Mine Plan Sequencing: incorporating Puro Corazon material early in the mine plan, given its near-surface and high-grade characteristic, is anticipated to strengthen project economics.
• Improved Project Economics: combination of capital efficiencies, optimized sequencing and potential throughput increases resulting in potential improvements to NPV and IRR.
• Additional Benefits: potential synergies and efficiencies across permitting, environmental management, safety and data collection.

Lawrence Page K. C., Company President, said, “The acquisition of Puro Corazon will allow us to derisk and accelerate the development of Cerro Las Minitas in a capital efficient manner, with significantly enhanced production profile and economics.”

Robert Macdonald, Vice President of Exploration, said, “I am excited about the opportunity to begin drilling at Puro Corazon, with numerous high-grade near-surface targets already identified. We have significant historic data from Puro Corazon that will guide exploration and the results of which will be incorporated into an updated PEA, and I am confident that we will be able to add significant value to the Cerro Las Minitas project.”

The Company has been granted the right to acquire the Puro Corazon mining claim from an arms-length vendor in consideration for a series of cash payments to be made over a forty-month period following entering into of a definitive assignment agreement with the vendor. The acquisition does not involve the issuance of any securities of the Company.
