FireFox Gold drills 124 g/t Au over 1.0 m at Mustajärvi, Lapland

FireFox Gold Drills Downdip Extension of East Zone, including 1.0m at 124 g/t Au at the Mustajärvi Project in Lapland, Finland

SODANKYLÄ, FI / ACCESS Newswire / September 1, 2026 / FireFox Gold Corp. (TSXV:FFOX)(OTCQB:FFOXF)("FireFox" or the "Company") is pleased to report assay results from six additional drill holes completed at its 100%-owned Mustajärvi Gold Project in Lapland, Finland. This work continues to provide data for the anticipated mineral resource estimate for the project. Five holes evaluated infill and step-out targets at the East Zone, and one hole drilled a step-out at the Northeast Zone (see Figure 1 and Table 1).

Highlights from these holes include high-grade intervals in hole 26MJ021 and 26MJ022 from the central part of the East Zone:

26MJ021: 4.0m averaging 1.64 g/t gold from 77.65m depth, including 1.0m at 5.04 g/t gold, and 2.0m averaging 63.19 g/t gold from 102.4m depth, including 1.0m at 124.0 g/t gold and 0.38% cobalt; and

26MJ022: 6.0m averaging 4.38 g/t gold from 128.0m depth, including 1.0m at 23.5 g/t gold from 132.0m.

Carl Löfberg, FireFox's CEO, commented "Our drilling continues to close gaps and push boundaries at both of the main zones at Mustajärvi (East and Northeast), as part of the core work for completing our maiden resource estimate. The high-grade intercepts in holes 26MJ021 and 26MJ022 are significant because we can see in cross section that these new intercepts demonstrate that the strong mineralization from the heart of the East Zone continues down dip along the shear zone. We are excited to test these deeper targets later in the program. We have also been drilling peripheral to the expected resource area, including at the Central Zone and the Triangle Target, so that we will have a number of new expansion targets ready to support further growth at Mustajärvi through our 2027 drilling program."
