FireFox Gold extends East and Northeast zones at Mustajärvi

FireFox Gold Drilling Extends East and Northeast Zones at Mustajärvi Project in Lapland, Finland

SODANKYLÄ, FI / ACCESS Newswire / August 5, 2026 / FireFox Gold Corp. (TSX.V: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. Three of the holes successfully expanded the Northeast and East gold zones, and three holes identified new gold mineralization in the area between those zones (see Figure 1 and Table 1). Drilling continues at the project with two rigs presently on site. FireFox significantly exceeded its plans for approximately 10,000 metres of drilling during the winter and spring campaign; and data from an additional 19 drill holes are pending.

Selected intervals from this round of results are highlighted below:

Drill hole 26MJ007 (East Zone): 2.9 metres at 11.55 g/t gold from 242.8 metres depth, including 2.0 metres at 16.48 g/t gold ;

Drill hole 26MJ006 (Northeast Zone): 5.9 metres at 5.09 g/t gold from 133.5 metres depth, including 1.0 metre at 23.9 g/t gold ;

Drill hole 26MJ010 (East Zone): 7.3 metres at 3.63 g/t gold from 142.5 metres depth, including 2.15 metres at 11.38 g/t gold ;

Drill hole 26MJ011 (Gap Zone): 1.5 metres at 16.11 g/t gold from 207.2 metres depth; and

Drill hole 26MJ006 (Northeast Zone): 5.5 metres at 3.99 g/t gold from 122.0 metres depth, including 1.5 metres at 11.77 g/t gold.

The most significant advancements from these six holes are new additions on the south and southwest side of the East Zone from drill holes 26MJ007 and 26MJ010 and the new intercept from 26MJ006 that advances the Northeast Zone to the northeast and closer to surface (see Figure 1). Current permit boundaries and buffer zones only permit limited drilling into the so-called Gap Zone, between the Northeast and East Zones, but all three holes into this gap intersected significant gold, including a substantial intercept i
