The Company's recent strategic land acquisitions have expanded the EDM Project to approximately 33,500 hectares, strengthening Fredonia's district-scale land position and providing a broader platform for long-term exploration across the surrounding mineralized corridor.

PEA Progress

The PEA continues to advance on track for completion by the end of August 2026 under the direction of independent engineering and technical consultants. The study represents the first integrated evaluation of potential development scenarios for EDM and is expected to provide an important technical framework for future engineering and development studies.

The PEA is evaluating a range of mining, processing and project development alternatives with the objective of identifying practical pathways to advance the Project while supporting future optimization opportunities.

In parallel with the PEA, the Company continues to refine its geological interpretation, resource model and supporting technical datasets as additional drilling information becomes available. Management believes these parallel workstreams will further strengthen the technical foundation supporting future engineering studies and long-term Project development.

Fredonia's flagship El Dorado Monserrat Project currently hosts a Measured and Indicated Mineral Resource of approximately 2.25 million gold equivalent ounces, as defined in the Company's NI 43-101 Technical Report (see Table 1 below). The Company is advancing its Preliminary Economic Assessment in parallel with an ongoing 10,000-metre drilling program focused on expanding the existing Mineral Resource while increasing geological confidence through targeted infill drilling. Together with the recently completed consolidation of the broader EDM district, these initiatives are designed to strengthen the Project's technical foundation, support the ongoing PEA and position the Company for continued long-term resource growth and future development.

Table 1

Gold equivalent grade (Au Eq) is derived using a gold price of US$1,800/oz, and silver metal price US$24/oz. Au Eq assumes Au and Ag recoveries of 90.0%. The limited metallurgical studies by Fredonia to date (selective Bottle rolls from Main Veins material) have indicated high (>90%) recovery of gold in oxide material. The Cerro Vanguardia mine to the east of EDM with similar mineralization reports recoveries higher than 90% for Au. Accordingly, the formula used for Au Eq is: Au Eq (g/t) = Au (g/t) + [Ag (g/t) x (24/1,800) x (0.9/0.9)]

Geo., and Fernando Ganem, P. Geo. The report is available on the Company’s profile on SEDAR+ at www.sedarplus.ca.

Drilling Update and Incoming Assay Results

The Company's ongoing drilling program continues to advance across priority target areas within the broader EDM district. To date, approximately 3,500 metres of diamond drilling have been completed as part of the Company's current 10,000-metre exploration and infill drilling program.

The Company has begun receiving assay results from the current drilling campaign, including results from infill drilling designed to increase geological confidence, refine the resource model and support the ongoing Preliminary Economic Assessment and future technical studies.

While assay results have started to be received, a substantial portion of the submitted samples remains in the laboratory process. As additional results continue to be received, validated and interpreted, the Company intends to provide shareholders with a comprehensive update once a sufficiently representative portion of the current drilling campaign has been completed.

Management believes the current drilling program will provide important geological information to further refine the Company's understanding of the mineralized system while supporting ongoing engineering, resource modelling and future development studies at EDM.
