Big Gold identifies gold targets at Martin Kenty

Compiled historical drilling includes 96.56 g/t Au over 0.38 metres at the Penn Showing and 31.00 g/t Au over 0.49 metres in the Heronry area Toronto, Ontario--(Newsfile Corp. - July 21, 2026) - Big Gold Inc. (CSE: BG) (FSE: H7L) (the "Company" or "Big Gold") is pleased to announce the results of the historical data compilation and target-generation review at its 100%-owned Martin Kenty Project in the Kenora Mining Division of northwestern Ontario. The review, which commenced on May 27, 2026 , was developed to identify numerous prioritized gold exploration targets and compiled historical drill intercepts, including 96.56 g/t Au over 0.38 metres 1 at the Penn Showing and 31.00 g/t Au over 0.49 metres 2 in the Heronry area. Highlights Numerous new gold exploration targets identified: priority targets across the Martin Kenty Project, based on the integration of historical geological, geochemical, geophysical and drilling datasets (see Figure 1).

High-grade historical drill intercepts compiled : Notable holes including 70449 which returned 96.56 g/t Au over 0.38 metres from 28.56 metres downhole at the Penn Showing 1 , hosted in a quartz-carbonate vein with visible gold, and 31.00 g/t Au over 0.49 metres from 37.26 metres in hole 70471-0 in the Heronry area 2 . Other notable Penn Showing historical intercepts : Returned 24.90 g/t Au over 0.26 metres 3 , 5.45 g/t Au over 1.46 metres 2 , 5.30 g/t Au over 0.49 metres 2 and 5.12 g/t Au over 0.61 metres 2 . Comprehensive gold exploration database now in hand: All publicly available assessment reports for the Project - historical drilling records, airborne geophysical surveys, regional geological mapping, and regional and property-scale geochemical surveys - were reviewed and digitized where appropriate, spanning operator records from 1975 to 2017.
