FireFox Gold Expands the East Zone to the Southwest with Ongoing Grid Drilling at the Mustajärvi Gold Project, FinlandSODANKYLÄ, FI / ACCESS Newswire / April 9, 2026 / FireFox Gold Corp. (TSX.V:FFOX)(OTCQB:FFOXF)("FireFox" or the "Company") is pleased to report the results from seven additional drill holes from its ongoing drill program at the Company's 100%-held Mustajärvi Gold Project in Lapland, Finland. Drill holes 25MJ016 through 25MJ021 were drilled in a fence configuration to probe the southwest extension of the East Zone, while drill hole 25MJ022 tested a magnetic low on the north side of the system (see Figure 1). All holes intercepted gold mineralization above the cutoff grade (see Table 1).The drilling to the south confirms that the high-grade gold system continues throughout this area, with significant mineralization encountered both in shallow intervals and at greater depths than in the previous surrounding high-grade holes 25MJ001 through 25MJ003 (see News Release dated October 27, 2025). Examples of the best intervals include:25MJ020: 5.0m averaging 6.29 g/t Au from 116m depth, including 1m at 24.9 g/t Au; and 13.0m averaging 4.57 g/t Au from 163.8m depth, including 3m at 11.66 g/t Au; and25MJ019: 9.85m averaging 3.52 g/t Au from 203m depth, including 0.85m at 13.15 g/t Au; and 3.0m averaging 4.63 g/t Au from 219m depth, including 1m at 13.25 g/t Au; and25MJ021: 3.0m averaging 12.07 g/t Au from 70m depth, including 1m at 29.2 g/t Au.Carl Löfberg, FireFox's CEO, commented about the new results, "As drilling continues, these results confirm strong gold mineralization in the southern part of the East Zone, which effectively extends the footprint of the system to approximately 400 by 250 metres. The East Zone remains open to the southwest, the west, and the northwest as it grows into the gap with the Northeast Zone. We also continue to intercept very interesting mineralization at depths of more than 200 metres, reminding us that all three of these gold zones are also open at depth. Most of these drill holes are collared at nominal spacing of approximately 50 metres, which is the spacing recommended by our resource geologist. Having completed 33 drill holes at Mustajärvi in this drill program, we look forward to steady news flow as results are processed from targets all along the mineralized trend."Mustajärvi Project and Drill Program SummaryThe Mustajärvi Project lies along the highway between the cities of Kittilä and Sodankylä, approximately 17 kilometres east of Kittilä. 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. Inclusive of these drill holes, the total drilling on the project is now 21,443 metres.Most of the drilling reported here is focused on the southwest flank of the growing East Zone deposit. Six of the seven holes in this release are comprised of fences of drill holes, directed to the northwest, aimed to fill-in and delineate the southern flank of the zone. Figure 1. Drill Holes 25MJ016 - 25MJ022 at the Mustajärvi Project, East Zone.Drill Fence 25MJ019 - 25MJ020 - 23MJ010All three of these holes were collared in shallow glacial sediments. Drill holes 25MJ019 and 25MJ020 passed directly into the ultramafic volcanic rocks of the Savukoski Group after the shallow overburden. The target mineralization in this area tends to occur beneath the contact with the underlying Sodankylä Group metasedimentary rocks. Both 2025 drill holes tested this target lithology and encountered significant mineralization. Whereas the hole from 2023 was collared too far north to test this contact zone, so it encountered only variably altered metasedimentary rocks and some narrow mineralized intervals (see Company news release dated February 28, 2024).The southernmost hole in the drill fence is 25MJ019, and it intersected the contact with metasedimentary rocks at 168.1 metres depth. This drill hole was well mineralized, intersecting several gold-bearing intervals starting from 203.0 metres downhole, including a highlight of 9.85 metres averaging 3.52 g/t Au. As FireFox geologists have noted from other drill holes into the southern lobe of East Zone mineralization, the alteration and gold mineralization in this area is often associated with mafic to ultramafic dikes and sill. Gold zones commonly occur along the contacts above and below the mafic dikes, where the metasediments are highly fractured and flooded with albite + pyrite, sericite, and quartz-carbonate-tourmaline-pyrite (QCTP) veins. In some cases, disseminated pyrite or specular hematite are good indications of mineralization. The dikes or sills (if they are close to flat lying or conformable with bedding) are usually altered, deformed, and highly fractured, but they are only rarely mineralized themselves.One such case of significant mineralization in a mafic
