FireFox Gold Announces Discovery of the Lammas Zone, Intersecting 21.0m at 4.13 g/t Gold
more than 650m from Previous Drilling at the Mustajärvi Project in Lapland, Finland
SODANKYLA , FINLAND – (September 16, 2026) – FireFox Gold Corp. (TSX.V: FFOX)(OTCQB:
FFOXF)(“FireFox” or the “Company”) is excited to announce the discovery of the “Lammas Zone” at its 100%-
owned Mustaja rvi Gold Project in Lapland, Finland . Lammas is a newly recognized high-grade gold-
mineralized zone that is nearly a kilometre east of the main Mustaja rvi Shear Zone (MSZ) (Figure 1). The
discovery drill hole, 26MJ032, intersected several gold-mineralized intervals, highlighted by:
• 21.0m averaging 4.13 g/t gold from 114.0m depth, including 1.0m at 21.6 g/t gold, and;
• 4.2m averaging 3.41 g/t gold from 138.0 metres depth.
Since the initial discovery in 2018, the Company’s focus has been on exploring the three known kilometres
of mineralization along the MSZ, making new discoveries at the Northeast and East Zones. Now that FireFox
is working towards completing its initial resource estimate for the project early in 2027 , the arrival of a
second drill rig has allowed testing of a broader array of targets across the property. Lammas is one of several
such priority targets that are receiving their first drill tests as targets for future resource growth at
Mustaja rvi.
Carl Lo fberg, FireFox’s CEO, commented “The results from this hole indicate just how much potential for
discovery and expansion remains in the Mustajärvi Shear Zone system. Here at Lammas, work is just beginning,
but this structural trend appears to have continuity over some appreciable distance. It is common in orogenic
gold systems to find mineralization along multiple structures, either parallel splays of a fault system or stepovers
where one system is offset but continues. We have now drill-tested the structure in both directions along strike
from the discovery hole, and geophysics and BoT geochemistry suggest that it could continue across the highway
onto our northern block and eventually to ground held by Agnico Eagle Mines, more than 1 kilometre away. We
plan to return to drilling on the structure in the coming weeks when winter conditions provide better access. In
the meantime, we look forward to assays from the two other holes we have completed at Lammas, as well as
from our other drilling at multiple targets throughout the project.”
Details of the New Discovery
The FireFox team conducted detailed ground magnetics across most of the tenement, and the team noted
several apparent structures with responses consistent with alteration along the MSZ. The Company has been
examining the broad structural setting around Mustaja rvi as expressions of the crustal-scale Venejoki Shear
Zone that passes along the southern margin of the tenement. The northeast striking structure that hosts the
Lammas discovery was further upgraded after detecting gold anomalies in base-of-till (BoT) sampling over
the new target. Finally, the FireFox team , working with its in -house geophysicist, Markku Mont onen from
2
Magnus Minerals, executed an electromagnetic survey at Lammas that returned conductors consistent with
the high-pyrite high-grade gold mineralization at the Northeast and East Zones.
As the first drill hole tested the target, FireFox geologists noted the characteristic intense albite alteration,
along with abundant quartz-carbonate and tourmaline veining and brecciation. The team moved quickly to
drill two additional holes at Lammas, along the same southwest -northeast (SW -NE) trend, testing
approximately 250 metres of the structure so far . In those holes, geologists also observed pyrite-tourmaline
veining associated with albitized and brecciated metasedimentary rocks, again consistent with the style of
mineralization encountered in the discovery hole.
The Company only has assays from one of the three holes, and there is no visible gold reported from any of
the Lammas holes so far . FireFox cautions that the presence of pyrite mineralization , and accompanying
favourable alteration, do not necessarily indicate the presence of gold mineralization in the two additional
holes at Lammas. Preliminary geological logging and estimates of prospectivity should not be relied upon.
Mustajärvi Project and Details of Drill Results
The Mustaja rvi Project lies along the highway between the cities of Kittila and Sodankyla , approximately 18
kilometres east of Kittila . FireFox and predecessor companies drilled approximately 15,752 metres prior to
commencement of the current program and delineated three different lodes of gold mineralization along
more than two kilometres of strike. Inclusive of this drill hole, the total drilling on the project is now 29,897
metres.
The high -grade gold mineralization at Mustaja rvi is almost always associated with abundant pyrite or
hematite (iron oxides). In 2025, FireFox successfully employed fixed-loop electromagnetic (FLEM) surveys
to identify gold in conductive (pyrite -dominant) horizons at the near -surface high-grade Mustaja rvi East
Zone (see Company news releases dated October 27, 2025 and December 8, 2025). This methodology allows
for visualization of conductive anomalies that may be related to gold mineralization. Anomalies that further
coincide with breaks in the magnetics and structurally complex zones are high-priority targets, as this setting
compares very favorably with the East Zone discovery.
In addition to its broad application of detailed magnetics, the Company initiated additional FLEM surveys on
targets lying up to 2 kilometres east of the East Zone. The surveys identified two well-defined anomalies
recommended for drill testing (see the Company’s news release dated January 12, 2026). The highest priority
of these was a strong conductive EM anomaly along an apparent northeast -striking structure or lithologic
contact that was already of interest. A BoT sampling program in this area also returned encouraging results,
indicating that the potential mineralized system identified by the FLEM work may extend farther along strike
towards the northeast. This area, now called the Lammas Zone, is located approximately 750 to 950 metres
east-southeast of the centre of East Zone (Figure 1). This work resulted in the three-hole reconnaissance
drilling program at Lammas earlier this summer to test the FLEM and BoT targets.
Drill hole 26MJ033 was collared approximately 60 metres southwest of the discovery hole to test the
continuation of the same electromagnetic anomaly, and drill hole 26MJ035 was collared approximately 200
metres to the northeast to test a BoT anomaly along the same trend.

Drill hole 26MJ032 tested the most prominent FLEM conductor plate and an interpreted splay of the
Mustaja rvi Shear Zone, a secondary fault system to and the most highly mineralized section along the regional
Venejoki Shear Zone. The splay corresponds to northeast-trending discontinuities interpreted from ground
magnetic data. The hole is collared in thin glacial sediments (approximately 13.0 metres deep) and passed
through the contact between ultramafic volcanic rocks and intensely altered metasedimentary rocks at a
depth of 86.8 metres. This is a familiar pattern seen at Mustaja rvi, as these ultramafic rocks overlie the
metasedimentary rocks as the contact and the shear zone dip south.
The hole successfully confirmed that the FLEM plates were associated with conductive rocks by intersecting
broad, stacked gold-bearing intervals associated with patchy and semi -massive pyrite mineralization
beginning at 114.0 metres downhole. The shallowest interval yielded 21.0 metres at 4.13 g/t Au, including
1.0 metre at 21.6 g/t Au at a depth of 118.0 metres. This interval is followed by a thin section of internal
waste (3.0 metres thick), after which the drill continued through another 4.2 metres averaging 3.41 g/t Au
from a depth of 138.0 metres, including 1.0 metre at 7.22 g/t Au. It is noteworthy that this high-grade zone
occupies the footwall of a significant fault zone, and the veins are clearly multi -generational, chaotic, and
often comprised of vein breccias.
Gold is associated with patchy and semi -massive pyrite and intense quartz-carbonate-tourmaline-pyrite
(QCTP) veining hosted in strongly albite- and silica- sericite- altered metasedimentary rock (Figure 2).

Tourmaline, a black variety referred to as schorl, is particularly abundant in these mineralized intervals,
forming semi-massive clots in the QCTP veins, apparent open space filling, and sometimes brecciated by
interstitial pyrite.
Deeper in the hole, the drill cut two additional narrow intervals with strong grade. These lower intervals are
associated with patchy and disseminated pyrite hosted in intensely albite- and silica-altered sections of mafic
intrusive rocks. The intervals returned 1.0 metre at 3.01 g/t Au from a depth of 186.0 metres and 1.0 metre
at 1.82 g/t Au from a depth of 191.0 metres.
Structural logging by Finnish specialist consultants Structural Geology Company (SGEO) indicates that the
mineralized interval in drill hole 26MJ032 is consistent with the deformation and other geological
characteristics of the Mustaja rvi Shear Zone system. SGEO confirms that the newly discovered mineralization
occurs within a northeast -trending deformation zone displaying the same quartz -tourmaline-pyrite
alteration assemblage observed in mineralized zones at the Northeast and East Zones. The overall alteration
and setting suggest repeated hydrothermal fluid flow within a long -lived structure. Based on these
5
correlations with other drill holes and previously modelled deformation zones, SGEO interprets the zone as
likely representing a separate branch or splay within a broader mineralized corridor.

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 so me 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
¼ core duplicates, crush stage duplicates, and insertion of certified standard and blank samples.
FireFox team members transported the samples to an ALS sample prep lab in Sodankyla . The samples were
sawed then crushed to -2 mm, split and pulverized into 1kg pulps, before being shipped to the ALS facility in
Rosia Montana, Romania for gold by fire assa y 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
