FireFox Gold Corp has reported final results of the Phase 2 diamond core drilling program at its 100% owned Mustajärvi Gold Project in the Central Lapland Greenstone Belt, Finland. This phase of drilling consisted of nine drill holes, with assays for the first five holes reported on November 26th, 2019. The program has significantly expanded the footprint of the Mustajärvi mineralization by intersecting massive tourmaline-quartz-pyrite veins approximately 500 metres northeast of the known Central Zone mineralization, including 0.85 metres averaging 24.7 g/t Au within 1.95 metres averaging 12 g/t Au in Hole 19MJ006. President and CEO of FireFox Gold Carl Löfberg said "The results from Mustajärvi continue to indicate that gold mineralization is associated with the Mustajärvi Shear Zone, potentially over more than 900 metres of strike length. There is potential to expand mineralization, particularly to the northeast of the Central Zone and around the Mustajärvi NE target."

Summary of Recent Results

Hole 19MJ007 was a step-out hole collared 250m southwest of the Mustajärvi Central Zone drill holes. It targeted a major bend in the Mustajärvi shear zone that is spatially associated with a strong IP chargeability anomaly and low resistivity values. This single drill hole intersected anomalous gold concentrations (1 metre averaging 0.15 g/t Au between 170.6-171.6 metres down hole) in proximity to the interpreted contact between metasediments and gabbro. Due to these anomalous values and the favorable lithological setting, "Mustajärvi SW" remains a valid target for additional follow-up drilling.

Drill holes 19MJ008 and 19MJ009 were drilled within the Mustajärvi Central Zone with the goal of extending the high-grade mineralization yielded earlier by 18MJ010 (2 metres averaging 45.1 g/t Au; see FireFox news release dated Jan 21, 2019). Drill hole 19MJ008 targeted an area between the high-grade mineralization and the most eastern drill hole of the Mustajärvi Central Zone. It intersected anomalous gold grades (1 metre averaging 0.18 g/t Au). Drill hole 19MJ009 targeted the continuation of the high-grade mineralization of 18MJ010 about 50 metres to the southwest. It intersected three narrow intervals of mineralization: 1 metre averaging 1.07 g/t Au from 105–106m down hole; 0.5 metre averaging 2.36 g/t Au and 0.1% Co from 112.1–112.6m down hole; and 1 metre averaging 3.49 g/t Au between 145–146m down hole.

The last drill hole, 19MJ003, was drilled almost perpendicular to the direction of all the other drill holes. Its purpose was to test a second mineralized structure (Trend 2; see FireFox new release dated Jan 3, 2019) which was identified during the trenching at the Mustajärvi Central Zone. While the gossanous samples collected from this trench yielded good grades (9 samples range from 0.05 to 7.91 g/t Au and averaging 2.05 g/t Au), the drilling identified a weakly anomalous zone measuring about 20-metres-wide that yielded peak values of 1 metre averaging 0.17g/t Au (between 10-11 metres down hole), 0.4 metres averaging 0.2 g/t Au (between 14.2-14.6 metres down hole) and 0.2 metres averaging 0.5 g/t Au (between 20.4-20.6 metres down hole). Due to difficult drilling conditions, the hole suffered from strong core loss, making the identification of representative grades of the Trend 2 mineralization ambiguous.

The results of these drill holes within the Mustajärvi Central Zone mineralization are interpreted to indicate that the high-grade zone, earlier intersected by drill hole 18MJ010, is discontinuous and displays the strong pinch-and-swell nature of the gold-mineralized veins at Mustajärvi.

Overall, the Phase 2 drilling campaign was successful in discovering new significant gold mineralization approximately 500 metres NE from the Mustajärvi Central Zone, indicating that the Mustajärvi Shear may be mineralized over at least 900 metres of its strike. The Mustajärvi SW area, 250 metres southwest of the Central Zone, warrants additional follow-up drilling to confirm the expansion of the Mustajärvi system in this direction.
