J2 Metals Inc. Announces Option to Acquire the District-Scale Sierra Plata Silver-Antimony Project in Taxco, Mexico

Vancouver, British Columbia--(Newsfile Corp. - December 22, 2025) - J2 Metals Inc. (TSXV: JTWO) ("J2" or the "Company") is pleased to announce that it has entered into a 3-year option with Impact Silver Corp. (TSXV: IPT) ("Impact"), a Mexican silver producer, to acquire the 2,200-hectare Sierra Plata Project, located in the Zacualpan District near Taxco, Guerrero State, Mexico.

The Sierra Plata Project hosts multiple past-producing silver mines, including El Salto and El Sabino, as well as numerous smaller historic workings. In addition to its silver endowment, the project is considered highly prospective for antimony, a strategic metal of increasing importance in global supply chains. The project is adjacent to mining claims held by Grupo México and Impact, and the Company believes that the historic San Miguel silver mine, a significant multi-level past producer, extends into the Sierra Plata project area. The Taxco region was, for centuries, one of the most important silver-producing districts in the Spanish Empire.

Project Highlights:

• District-scale land package in a major historic silver district.
• Multiple past-producing silver mines located within the project area.
• Numerous productive trends and fault structures identified across the project.
• Strong silver and antimony prospectivity.
• Access to Impact's local technical expertise and regional drilling infrastructure.

J2 also announces that Simon Clarke has been appointed to the Company's board of directors.

Thomas Lamb, CEO of J2, commented: "We are delighted to have struck this exciting deal with Impact on the Sierra Plata Project, a large and highly prospective land package within a historic silver district. Under Mexican mining regulations, certain concessions require regular investment, and Sierra Plata lies outside Impact's current production focus, creating a compelling opportunity for J2 to advance the project.

"Sierra Plata hosts five historic silver mines and numerous historic workings. The historic, multi-level San Miguel Mine, which ceased production in the 1930s, is understood to extend from Grupo México ground into the Sierra Plata Project. We believe that at current silver prices San Miguel is a strong candidate for a production restart, which would obviously be an exciting catalyst for J2.

"Beyond visiting several historic mines and workings, our team's recent site visit to Sierra Plata confirmed multiple vein systems and structural trends in and around the project. Prior work by Impact indicates that important regional mineralized trends extend across the Sierra Plata land package. With Impact focused on its core producing areas, J2 is well positioned to advance exploration on this important part of the broader district.
