Technical Report Authorship and NI 43-101 Compliance for the EDM Project

The technical report, formally titled "NI 43-101 Technical Report – Preliminary Economic Assessment, El Dorado – Monserrat Gold-Silver Project," was prepared by three qualified persons: Sergio Alvarado Casas, R.M. (Geology), Ricardo Muñoz González, R.M. (Mining), and Carlos Puga Gómez, R.M. (Mining), all registered members of Chile's Comisión Calificadora de Competencias en Recursos y Reservas Mineras de Chile. Alvarado Casas, the principal author, serves as an independent consultant through Geoinvest Limitada and is confirmed independent of Fredonia within the meaning of NI 43-101. All three authors meet the Canadian regulatory definition of qualified persons.

EDM Project Scale and Location Within Argentina's Deseado Massif

The EDM project spans approximately 33,500 hectares in Santa Cruz province and forms the centrepiece of Fredonia's broader Argentine land package of approximately 64,000 hectares across three licence areas in the Deseado Massif geological region. The project is situated near AngloGold Ashanti's Cerro Vanguardia gold-silver mine, which the release states produced approximately 180,000 ounces of gold during the twelve months ended June 30, 2026, based on publicly available third-party data. The company notes that Cerro Vanguardia's performance is not necessarily indicative of the EDM project's mineralization or economic potential.

Connection to August 2026 PEA Results and Recent Financing Activity

The technical report serves as the formal NI 43-101 support document for PEA results announced August 31, 2026. That earlier release disclosed project economics including figures for annual gold-equivalent production, net present value, and internal rate of return. Separately, the company announced the closing of a C$11.5 million bought deal private placement in September 2026, including the full exercise of an underwriters' option, suggesting ongoing capital activity around the EDM asset ahead of potential further study work.
