FireFox Continues to Broaden the East Zone with Excessive-Grade Drill Outcomes, together with 13.75 g/t Gold over 12.4 Metres in One other Step-out Gap on the Mustajärvi Gold Venture, Finland

SODANKYLÄ, FINLAND / ACCESS Newswire / December 8, 2025 / FireFox Gold Corp. (TSX.V:FFOX)(OTCQB:FFOXF)(“FireFox” or the “Firm”) is happy to report outcomes from a further 4 holes of its 2025/26 diamond drilling program on the Firm’s 100%-held Mustajärvi Gold Venture in Lapland, Finland. Drill gap 25MJ005 is among the many finest holes but drilled on the property, extending each shallow and deeper high-grade gold zones properly to the west from earlier drilling on the East Zone. Highlighted intervals are proven under:

• 12.4 metres averaging 13.75 g/t Au from 37.9 metres

• 3.75 metres averaging 19.65 g/t Au from 99.85 metres

• 5.7 metres averaging 17.71 g/t Au from 217.0 metres

The 4 holes reported on this launch (25MJ005 – 25MJ008) take a look at for extensions of mineralization within the East and Northeast Zones (Determine 1). Every gap intersected gold-elevated zones, together with high-grade intercepts as proven in Desk 1, and offered helpful details about the controls on and continuation of the mineralized system on the Mustajärvi Venture.

Carl Löfberg, FireFox’s CEO, commented in regards to the new outcomes, “Drill gap 25MJ005 is an excellent consequence for the expansion of the Mustajärvi discovery. Mixed with drill gap 25MJ001, these two holes show continuity of the East Zone gold system properly to the southwest from the high-grade core we found in 2022. Even higher, the system appears to be strengthening on this most up-to-date gap over the 45-metre step out from 25MJ001, as each gold and tellurium grades improve. Each of those holes confirmed a robust electrical geophysics anomaly with stacked intervals of high-grade gold. Each the shallow (<100m depth) and deeper lodes seem to show comparable geochemistry and alteration over greater than 200 metres of strike. The reliability of our geophysical toolkit mixed with the excessive grade and bettering continuity across the East Zone discovery are essential as a result of our workforce can now use this information to infill and develop the East Zone, in addition to take a look at different targets at Mustajärvi. Drilling continues and we’ve got much more drill holes to return!”

This work is a part of the continuing program of as much as 10,000 metres of diamond drilling deliberate for Mustajärvi by way of spring of 2026. This system mixes infill and step-out drilling at current mineralized zones, and it additionally checks some new targets each proximal and distal to the principle mineralized buildings. The workforce accomplished the primary spherical of drilling in late October, together with 15 drill holes totalling 3985.3 metres. Ultimate assays are pending for the remaining seven holes from the primary part. The workforce at the moment are conducting the second spherical of drilling, which is anticipated to run to the top of January 2026.

Mustajärvi Venture and Drill Program Abstract

The Mustajärvi Venture lies alongside the freeway between the cities of Kittilä and Sodankylä, roughly 17 kilometres east of Kittilä. The undertaking is at a comparatively early stage as FireFox and predecessor corporations have drilled roughly 15,752 metres previous to the graduation of this program. Drilling has to this point delineated three completely different lodes of gold mineralization alongside greater than 1.5 kilometres of strike. Of the newly reported drill holes 25MJ005, 25MJ006 and 25MJ008 examined for extensions to the East Zone mineralization in three instructions, whereas 25MJ007 examined a niche inside the Northeast Zone drilling (Determine 1).

Drill gap 25MJ005 examined the conductive zone beforehand recognized by fastened loop electro-magnetic (FLEM) geophysical survey (reported February 20, 2025). An earlier gap from this program, 25MJ001, was collared 45 metres to the northeast and intersected stacked intervals of high-grade gold mineralization coinciding with the conductor, as reported on October 27, 2025.

This gap was collared in skinny glacial sediments (roughly 9.0 metres deep), overlying ultramafic volcanic rocks. Excessive-grade gold mineralization begins instantly after the contact between ultramafic volcanic rocks and intensely albite-altered and silicified intermediate tuffites. Gold right here is related to patchy and semi-massive pyrite mineralization, accompanied by quartz-carbonate-tourmaline-pyrite (QCTP) veining and brecciation. The primary mineralized interval yielded a high-grade gold zone of 12.4 metres averaging 13.75 g/t Au from 37.9 metres downhole, together with 4.1 metres averaging 37.45 g/t Au (Determine 2). This high-grade zone is adjoining to a mafic dike or sill (typically the dikes are of ultramafic composition), which is a recurring theme for the high-grade zones at Mustajärvi.

One other excessive grade-grade gold interval of observe was intersected from 99.85 metres downhole returning 3.75 metres averaging 19.65 g/t Au, together with 0.8 metres at 53.3 g/t Au and 1.0 metre at 24.6 g/t Au. Mineralization is related to patchy and semi-massive pyrite hosted in intensely albite-altered metasediments.

These shallower intervals of high-grade gold mineralization are related to enrichment within the typical suite of pathfinder parts seen on the Mustajärvi East, Northeast, and Central Zones: bismuth (Bi), tellurium (Te), molybdenum (Mo), selenium (Se), and cobalt (Co).

Importantly, the opening intersected deeper high-grade gold mineralization from 217.0 metres related to a fault-breccia zone with quartz infill and missing pyrite mineralization (Determine 3). This deeper interval yielded 5.7 metres averaging 17.71 g/t Au, together with 1.4 metres at 48.7 g/t Au (the longer interval contains 1.4 metres of core loss). Along with being a lot decrease in pyrite and albite, the hint ingredient geochemistry of this decrease interval is considerably completely different, most notably decrease in Bi and Mo.

As well as, there are a number of slender intervals of anomalous gold intersected between 239 metres depth and the top of the opening (305.5m), together with 4 particular person intercepts grading between 0.55 g/t Au and 1.19 g/t Au.

Drill gap 25MJ006 prolonged the fence of holes made by 25MJ002 to 25MJ004 (See Firm information launch dated October 27, 2025). It was collared 125 metres additional to the northwest (Determine 1) to check the lithological controls of mineralization on this course. The opening drilled intensely altered metasediments and intersected three slender mineralized intervals above 0.5 g/t Au. Probably the most notable interval was at 145 metres depth and returned 1.0m at 16.8 g/t Au. The high-grade mineralization is related to a brecciated interval together with QCTP veining inside intensely altered metasediments.

Drill gap 25MJ008 was designed to check for an japanese continuation of the East Zone. The opening was collared in skinny glacial sediments (roughly 8.4 metres deep) overlying Savukoski Group ultramafic volcanics. The opening intersected a mineralized contact between the ultramafic volcanic rocks and intensely albite-altered metasediments with QCTP veining at 143.8 metres, the place a 1 metre interval yielded 0.65 g/t Au. The most effective intercept within the gap returned 2.13 g/t Au over 1.7 metres ranging from 181.0 metres, hosted in strongly albite-altered intermediate tuffites with QCTP veining.

Drill gap 25MJ007 was the primary gap of this system to revisit the Northeast Zone. Restricted earlier drilling on this zone recognized altered metasediment sequences, QCTP veining, and breccias that hosted high-grade gold intervals, just like these later encountered on the East Zone. The strongest and thickest mineralization within the space occurred in a cluster of holes on the northeastern restrict of drilling within the space (see Determine 1). This included bonanza intercepts akin to 1.35m averaging 93.88 g/t Au, together with 0.65m at 129.5 g/t Au at 184.14 metres depth in 21MJ001 and 16.45m at 7.69 g/t Au from 154.2 metres depth in 21MJ010 (reported on June 17, 2021 and September 9, 2021, respectively).

This gap examined a niche in drilling roughly 100 metres to the west. The opening was collared in skinny glacial sediments (roughly 5.8 metres deep) overlying Savukoski Group ultramafic volcanics. It handed by way of a contact between the ultramafic volcanic rocks and intensely albite-altered metasediments at 30.9 metres depth, reducing a number of intervals with anomalous gold grades. Probably the most notable interval yielded 0.95 metres at 3.35 g/t Au from 138.15 metres depth. Mineralization is managed by QCTP veins and veinlets with disseminated pyrite hosted in intensely albite-altered intermediate tuffites. Further holes within the 2025/2026 program will take a look at for a northeast extension of the Northeast Zone.

Methodology & High quality Assurance

The core was transported from the rig to the Firm´s core storage facility in Sodankylä, the place FireFox’s exploration workforce carried out the geological and geotechnical logging and chosen the assay intervals. Assay intervals had been usually 1 metre however in some circumstances had been modified in line with lithological boundaries and different components. FireFox geologists maintained chain of custody and sampling procedures in line with finest trade observe and with due consideration to high quality assurance and high quality management, together with sampling ¼ core and crush stage duplicates and insertion of licensed commonplace and clean samples.

FireFox workforce members transported the drill core samples to an ALS pattern prep lab in Sodankylä or to the GeoPool Exploration Hub for core reducing. The cut up drill core samples had been then crushed to -2 mm, cut up and pulverized into 1kg pulps at ALS Sodankylä, earlier than being shipped to the ALS facility in Rosia Montana, Romania for gold by hearth assay of fifty gm aliquots with AAS end (technique Au-AA26). All samples exceeding 50.0 g/t Au had been re-assayed with a gravimetric end (technique Au-GRA22). Different parts, altogether 48, had been measured after four-acid digestion by ICP-AES and ICP-MS (technique ME-MS61) on the ALS facility positioned in Loughrea, Eire.
