FireFox Gold intercepts 4.13 g/t Au over 21.0 m at Mustajärvi, Lapland

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

SODANKYLÄ, FI / ACCESS Newswire / September 16, 2026 / FireFox Gold Corp. (TSXV:FFOX)(OTCQB:FFOXF) ("FireFox" or the "Company") is excited to announce the discovery of the "Lammas Zone" at its 100%-owned Mustajärvi Gold Project in Lapland, Finland. Lammas is a newly recognized high-grade gold-mineralized zone that is nearly a kilometre east of the main Mustajärvi 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 Mustajärvi.

Carl Löfberg, 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 coul
