Drill Results

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 Gold

SODANKYLA , FINLAND – (February 25, 2026) – FireFox Gold Corp. (TSX.V: 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 Mustaja rvi 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, including

o 2.6 metres at 15.87 g/t gold; and

• 7.6 metres at 32.25 g/t gold from 172.0 metres depth, including

o 0.8 metres at 188.5 g/t gold

The 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 Lo fberg, 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 Mustaja rvi, 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.

Mustajärvi Project and Drill Program Summary

The Mustaja rvi Project lies along the highway between the cities of Kittila and Sodankyla , approximately 17

kilometres east of Kittila . 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 Mustaja rvi 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 holes in the East Zone, this hole encountered multiple stacked gold intervals. At 159.4

metres downhole, the drill passed through 9.5 metres of albite-altered metasedimentary rocks (tuffites) with

abundant quartz-carbonate-pyrite and quartz-hematite-pyrite veining, which included significant gold, the

drill cut 3.1 metres of altered mafic dike or sill. Beneath the dike, the metasedimentary rocks are again

intensely altered and cut by more quartz -hematite and quartz -pyrite-tourmaline veins over 7.2 metres of

strongly gold mineralized rocks. Gold grade trails off into less altered rocks after the visible gold interval at

177.8 metres depth (0.8 metres of 188.5 g/t gold)(See Figure 2).

FireFox geologists identified and photographed numerous occurrences of grains of coarse visible gold in two

sections of alteration and veining, from 159.60 m to 159.85 m and 178.03 m to 178.30 m, as seen in the

examples in Figure 2 . In the upper section at 159.9 metres depth, the VG occurs as discrete flakes (up to

0.5mm across) in quartz vein with minor disseminated pyrite and chlorite (green mica) clumps. In the second

interval at 178.3 metres dept h discrete flakes of VG are a bit larger (up to 1.0mm across) and are spread

across the fracture surface of a vuggy textured and oxidised quartz vein with disseminate d pyrite

(approximately 2-5% pyrite) as shown in Figure 3.

Figure 2. Examples of the visible gold in 25MJ012 within quartz veins at 159.9m and 178.3m downhole.

The upper mineralized intervals described above, which host the VG, are comprised of strongly albite altered

and moderately silicified and hematite altered metasediments . Quartz and quartz -carbonate-tourmaline-

pyrite (QCTP) veins and vein breccias are associated with the highest grades and VG. Given the high degree

of alteration and deformation evident in this drill core, FireFox geologists do not yet have enough information

to confirm whether this new high -grade zone is attributable to the Mustaja rvi Shear Zone or the crossing

structure believed to pass through the area.

However, there are three additional gold -mineralized intervals deeper in the drill hole, which may be

associated with cross cutting structures. Most notably, a 1.4 metre zone averaging 4.44 g/t gold from 228.9

metres depth includes intensely brecciated albite-altered metasediments with abundant tourmaline and

QCTP veining. The team is still compiling structural information and modelling the mineralized zones in three

dimensions.

flakes.

Drill hole 25MJ013 is the easternmost hole at the East Zone. It was collared approximately 85 metres east

of hole 22MJ007, where it was aimed at the projected trace of the MSZ. The new hole intersected three narrow

gold-mineralized intervals with grade s up to 3.41 g/t gold, indicating the continuation of the mineralized

footprint along strike to northeast.

This hole was collared in thin glacial sediments (approximately 6.5 metres deep), overlying ultramafic

volcanic rocks. The first gold mineralized interval was intersected immediately after the contact with strongly

albite-altered metasediments from 100.5 metres depth and yielded 0.9 metres at 3.41 g/t gold. Gold is

associated with patchy pyrite mineralization accompanied by QCTP veining. At 114.0 metres depth, the drill

cut another interval that returned 1.0 metre at 3.09 g/t gold, hosted in brecciated and strongly sericite and

albite altered metasediments with abundant disseminated pyrite mineralization and quartz veining. Th ese

gold-mineralized intervals are again adjacent to a mafic dike, which is a common occurrence in the multiple

mineralized horizons at Mustaja rvi East.

Drill hole 25MJ014 tested for a northwest extension of the East Zone towards the gap zone tested by

25MJ012. The Mustaja rvi Shear Zone likely passes through the area where there is a steep gradient from

magnetic high to magnetic low. The hole was collared approximately 100 metres SSW from hole 25MJ011 in

strongly deformed, oxidised and pervasively altered metasediments, likely affected by the proximity to the

fault zone.

The hole only encountered relatively low-grade mineralization associated with abundant albite and hematite

alteration, but the intense alteration suggests a possible near -miss of higher gold grades nearby. From 69.0

metres depth, one interval assays 0.575 g/t gold over 2.0 metres. Another interval from 74.0 metres depth

yielded 0.77 g/t gold over 4.2 metres. Interestingly, these gold intercepts were also adjacent to altered but

unmineralized mafic dikes.

Drill hole 25MJ015 tested for an eastern extension of near-surface high grade gold mineralization within

the East Zone. The h ole was collared approximately 38 metres east of surface trench MJT202 4-1 which

returned 10.1 metres averaging 13.79 g/t gold (See Company news release dated Nov 21, 2024 ). The hole

confirmed an expansion of near -surface high-grade gold mineralization starting immediately beneath the

thin glacial sediment cover (approximately 8.0 metres deep) with an interval of 2.0 metres averaging 12.56

g/t gold, including 1.0 metre at 22.7 g/t gold. This mineralized interval just below the glacial cover is hosted

in albite-altered and silicified metasediments with abundant quartz veining , brecciation, and pyrite, both

disseminated and in clots.

The drill hole continued through another mafic dike, below which a gold mineralized zone occurred from

39.3 metres depth that yielded 1.08 g/t gold over 3.0 metres. The mineralization in this interval is hosted in

strongly albite-altered and silicified metasediments with common quartz-carbonate-pyrite veining.

Deeper in the hole at 62.0 metres depth, the drill cut a wider mineralized interval that returned 1.16 g/t gold

over 5.0 metres , including 1.0 metre of 3.43 g/t gold. Once again, the gold is hosted in strongly altered

metasediments with QCTP veining and disseminated pyrite between mafic dikes.

Notably, this drill hole intersected several more narrow low-grade gold mineralized intervals with grades up

to 0.66 g/t gold. Most of the gold intercepts in this hole are associated with the margins of mafic dikes. The

ongoing 3D modelling of the Mustaja rvi East Zone continues to reveal the importance of certain mafic dikes

in localizing fluid flow and concentrating gold grades. These dikes appear to account for some of the repeated

stacked gold intervals that contribute to the high grade-thickness of gold mineralization in the East Zone.

Methodology & Quality Assurance

The core was transported from the rig to the Company´s core storage facility in Sodankyla , where FireFox’s

exploration team conducted the geological and geotechnical logging and selected the assay intervals. Assay

intervals were generally 1 metre but in some circumstances were modified according to lithological

boundaries and other factors. FireFox geologists maintained chain of custody and sampling procedures

according to best industry practice and with due attention to quality assurance and quality control, including

sampling ¼ core and crush stage duplicates and insertion of certified standard and blank samples.

FireFox team members transported the drill core samples to an ALS sample prep lab in Sodankyla or to the

GeoPool Exploration Hub for core cutting. The split drill core samples were then crushed to -2 mm, split and

pulverized into 1kg pulps at ALS Sodankyla , before being shipped to the ALS facility in Rosia Montana,

Romania for gold by fire assay of 50 gm aliquots with AAS finish (method Au -AA26). All samples exceeding

50.0 g/t Au were re -assayed with a gravimetric finish (method Au -GRA22). Other elements, altogether 48,

were measured after four -acid digestion by ICP-AES and ICP -MS (method ME -MS61) at the ALS facility

located in Loughrea, Ireland.

ALS Laboratories is a leading international provider of assay and analytical data to the mining industry. All

ALS geochemical hub laboratories, including the Irish facility, are accredited to ISO/IEC 17025:2017 for

specific analytical procedures. The Firef ox QA/QC program consists of insertion of certificated standard

material and blanks inserted by Firefox into the analytical batches did not show deviations from

recommended values.
