FireFox Gold Reports Second Best Intercept Ever at Mustajärvi Project: New Target Between Northeast and East Zone Returns 7.6 Metres at 32.25 g/t Gold with Visible GoldSODANKYLÄ, FI / ACCESS Newswire / February 25, 2026 / FireFox Gold Corp. (TSXV:FFOX)(OTCQB:FFOXF)("FireFox" or the "Company") is pleased to report results from four additional drill holes of its 2025/26 diamond drilling program at the Company's 100%-held Mustajärvi Gold Project in Lapland, Finland. All holes were successful step-outs around the East Zone, but drill hole 25MJ012 is particularly notable as it returned one of the best gold mineralized intervals to date from the project, including significant visible gold (VG), while filling in a gap between two zones of mineralization (see Figures 1 and 2).Hole 25MJ012 passed through two highly mineralized intervals of intensely altered and veined metasedimentary rocks separated by a weakly altered mafic dike. The two intervals are summarized below:9.5 metres at 4.82 g/t gold from 159.4 metres depth, including2.6 metres at 15.87 g/t gold; and7.6 metres at 32.25 g/t gold from 172.0 metres depth, including0.8 metres at 188.5 g/t goldThe Company notes that only one intercept in the project's history, from drillhole 22MJ006 (13.85 metres at 28.74 g/t gold) exceeded this result from 25MJ012 when comparing grade-thickness of a mineralized interval (gold grade in g/t * thickness in metres) (See Company news releases dated July 13 and September 6, 2022).The high-grade gold in 25MJ012 supports the interpretation that mineralization could extend between the Northeast and East zones, potentially increasing the mineralized footprint to roughly 1.1 kilometres in the E-W direction. In addition, this new gold mineralized interval appears to tie into an interpreted NNW-SSE trending cross-structure that connects with the Triangle Target 500 metres to the northwest (See Figure 1).Carl Löfberg, FireFox's CEO, commented about the new results, "By confirming significant high-grade mineralization in 25MJ012 between what we call the East and Northeast Zones, we can more clearly envision the potential to bring the zones together into a single gold zone spanning more than a kilometre. The geophysics and structural setting in this target area suggest there is a lot of room to build from this intercept. The surface gold results from the undrilled Triangle Target are more than 500 metres away from this intercept along an apparent fault zone. We look forward to more drilling in the area as we continue working towards an expected maiden resource estimate at the project."Each of the other three holes released today encountered significant gold mineralization around the East Zone. Drill holes 25MJ013 and 25MJ015 extended the East Zone to the northeast with intercepts such as 2.0 metres averaging 12.56 g/t gold from 8.0 metres downhole (25MJ015), 5.0 metres of 1.16 g/t gold from 62.0 metres downhole (25MJ015), and 0.9 metres of 3.41 g/t gold from 100.5 metres downhole (25MJ013). Drill hole 25MJ014 also hit lower grade mineralization (4.2 metres at 0.77 g/t gold) in a previously undrilled gap to the northwest of the East Zone.This work is part of the ongoing diamond drill program at Mustajärvi, which is expected to exceed 10,000 metres before the end of spring 2026. The program mixes infill and step-out drilling at existing mineralized zones and tests some new targets both proximal and distal to the main mineralized structures. The team has now completed the first two rounds of drilling, including 30 drill holes totalling 7,662.2 metres. Logging of drill core is ongoing, and assays are pending for the remaining 15 drill holes. The third round of drilling is expected to commence by mid-March 2026. Figure 1.

FireFox and predecessor companies have drilled approximately 15,752 metres prior to commencement of the current program, and drilling has so far delineated three different lodes of gold mineralization along more than two kilometres of strike.Drill hole 25MJ012 was collared 100 metres NW from the previously reported hole 25MJ005 which intersected 13.75 g/t Au over 12.4 metres (see Company news release dated December 8, 2025). The drill target in this area is a combination of attractive geophysics and an interpreted structural intersection. There is a widespread magnetic low along and south of the projected trace of the Mustajärvi Shear Zone (MSZ). This was the second hole aimed at testing the interpreted NNW-SSE trending structure that bisects the gap between the Northeast and East Zones. Drill hole 25MJ012 was drilled from the opposite direction than previously reported 25MJ010, cutting the target zone at a more favourable angle (see Figure 1).As in many of the drill hole
