Big Gold Inc. Unveils Key Gold Exploration Targets at Martin Kenty Project After Extensive Historical Data Analysis

Comprehensive Historical Data Review Completed

On July 21, 2026, Big Gold announced the completion of a historical data compilation and target generation review at its Martin Kenty Project. The process, which started on May 27, 2026, aimed to identify prioritized gold exploration targets by integrating historical geological, geochemical, geophysical, and drilling datasets. The project was overseen by Morgan Verge, P.Geo., a Qualified Person under National Instrument 43-101.

The review digitized and examined all publicly available assessment reports related to the Martin Kenty Project, encompassing historical drilling data, airborne geophysical surveys, regional geological mapping, and geochemical surveys at both regional and property scales. Past operators involved between 1975 and 2017 included Noranda Exploration, Canadian Nickel, Barrier Reef Resources, Granges Exploration, Rio Algom Exploration, Wasabi Resources, and Vanity Capital, representing over four decades of exploration activity.

Noteworthy High-Grade Historical Drill Intercepts

The compilation documented numerous historic gold mineralization intercepts at Martin Kenty. The standout intercept was 96.56 g/t Au over 0.38 metres at 28.56 metres downhole in hole 70449 at the Penn Showing. This intercept occurs within a quartz-carbonate vein surrounded by a mineralized wall-rock envelope containing pyrite, arsenopyrite, and chalcopyrite, with 12 visible gold specks recorded in the historical log.

Another significant intercept was 31.00 g/t Au over 0.49 metres at 37.26 metres downhole in hole 70471-0 in the Heronry area, featuring a smoky grey, pyrite-rich, chloritic quartz-carbonate vein parallel to foliation, encased by a light green to white fuchsite alteration halo. Additional Penn Showing intercepts include four holes grading 24.90 g/t Au over 0.26 metres, 5.45 g/t Au over 1.46 metres, 5.30 g/t Au over 0.49 metres, and 5.12 g/t Au over 0.61 metres.

Detailed Historical Drill Intercept Table Included

The announcement provides a detailed table of 27 historical drill intercepts with gold grades ranging from 96.56 g/t Au to 1.02 g/t Au and core lengths between 0.22 metres and 1.52 metres. It is noted these are core lengths as reported in historical filings, with true widths unknown. The company emphasizes these intercepts pre-date National Instrument 43-101 and its involvement with the property.

Big Gold has not independently sampled, twinned, or verified these historical drill holes, and original sample preparation, analytical, and QA/QC procedures cannot be confirmed. The Qualified Person has not conducted sufficient verification work, and the company does not treat these as current, verified exploration results. Verification would require confirmatory work such as core review or twinned drilling, which may be pursued in future programs.

Integration of Multi-Disciplinary Data for Target Prioritization

The compilation integrated geological, geochemical, and geophysical datasets to identify coincident areas of interest, enabling ranking of exploration targets from high to lower priority based on overall prospectivity. This ranked target set, along with compiled historical drill intercepts, is depicted in a project map dated July 12, 2026. According to Morgan Verge, P.Geo., this approach systematically highlights areas where multiple data types suggest mineralization potential, guiding future exploration efforts.

The integrated datasets form the basis of the project’s exploration target ranking, directing subsequent exploration and drill planning. This methodical data consolidation aligns with industry standards for preparing legacy exploration information for field follow-up, focusing resources on the most promising zones before drilling.

Summer 2026 Field Program Progress and Plans

Big Gold reports that an agreement with a field exploration contractor for the summer 2026 program at Martin Kenty is in advanced stages, with execution expected soon. As of the announcement date, no agreement has been finalized, and the program remains contingent on final terms, permits, and financing. Further details will be released once the agreement is executed.

The planned field program aims to validate the prioritized targets identified through the compilation by on-the-ground investigation, refining target priorities and informing locations for potential drilling. This field validation step is standard in exploration workflows, narrowing focus from desktop analysis to site-specific assessment ahead of drilling. The timing during summer 2026 coincides with optimal field conditions in Ontario.

Regional Setting and Nearby Exploration Activity

The Martin Kenty Project is situated within the same regional tenure as SEVA Mining Corp.'s Cameron Deposit, located northeast along trend from Big Gold’s property. SEVA has publicly reported a Mineral Resource Estimate at Cameron of 0.515 million ounces of gold Measured and Indicated at 2.44 g/t Au, and 0.740 million ounces of gold Inferred at 2.18 g/t Au. The Cameron Deposit is a third-party asset owned by SEVA Mining and is referenced solely for regional context.

Big Gold clarifies it holds no interest in the Cameron Deposit and cautions that proximity to projects with gold resources does not guarantee similar rock types, mineralization, or gold deposits extend onto its property. The company emphasizes that adjacency to known resources is not necessarily indicative of mineralization on its tenements, consistent with standard exploration disclosure practices.

Martin Kenty Project Overview and Exploration Status

The Martin Kenty Project is one of Big Gold’s two flagship exploration properties in Ontario, alongside the Tabor Project. The project remains at an early exploration stage. Historical work has identified multiple gold occurrences through surface sampling and prospecting by previous operators and Big Gold.

During Big Gold’s 2022 exploration program, grab samples returned up to 8.37 g/t Au and 8.04 g/t Au, helping define priority areas linked to favourable intrusive and structural settings prospective for gold mineralization. These results have been incorporated into the current target-ranking framework derived from the historical data compilation.

Qualified Person Oversight and Verification Status

Morgan Verge, P.Geo., the Qualified Person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical content of the announcement. The Qualified Person ensures disclosed exploration information meets professional and regulatory standards. However, the announcement notes that references to mineral resources, historical estimates, and exploration results on adjacent properties are for contextual purposes only and do not necessarily reflect Big Gold’s mineralization potential.

The announcement further clarifies that third-party information, including historical drill results from previous operators and SEVA Mining’s mineral resource estimate, has not been independently verified by Big Gold or the Qualified Person. While Big Gold’s own data and analysis have been reviewed, historical intercepts pre-date NI 43-101 and lack modern verification.

About Big Gold Inc. and Forward-Looking Statements

Big Gold Inc. is a junior mining exploration company focused initially on exploration at the Martin Kenty and Tabor projects in Ontario. The company aims to acquire and develop early-stage base and precious metal projects, emphasizing Ontario-based assets. The announcement includes standard forward-looking information disclaimers, noting that execution of planned programs depends on factors such as property access, weather, personnel and contractor availability, financing, permits, regulatory approvals, and commodity price stability.

Management believes assumptions underlying forward-looking statements are reasonable but cautions against undue reliance. Forward-looking statements are made as of July 21, 2026, and Big Gold disclaims any obligation to update such information publicly due to new data, events, or results.
