FireFox Gold Corp. (TSX.V: FFOX) has announced that it has finished a small drilling program at its Mustajärvi Project in Finland to offset a recently discovered high-grade zone in the East Target. On July 13, 2022, FireFox announced that the company had completed a drill program at Mustajärvi (13.85m at 14.39 g/t gold in drill hole 22MJ006). That near-surface mineralization was discovered (less than 20m vertical). The drill hole returned significant coarse gold in one of the samples.
The subsequent screen fire assays detected significant coarse gold in one of the samples. The more rigorous screen fire assays returned a calculated total gold for one of the 227.4 g/t gold samples. All the section’s high-grade samples (more than 10 g/t) were confirmed by gravimetric finish and by 1,000-gram screen fire assays. A new weighted average of 13.85m at 28.74 g/t gold was calculated for drill hole 22MJ006.
The FireFox team devised a drilling program with five holes to examine an alternative route and seek further extensions of the new shallow high-grade zone. The program was designed to test for further high-grade zones downhole and to the southwest. This program’s shallow drill holes ranged from 100 to 160m in depth. One hole was drilled to a depth of 267m.
The program was successful in finding further extensions of the shallow high-grade zone. These new zones were found to be downhole and to the southwest of the original zone.
Drillhole 22MJ006 was the sixth drill hole along a 1.5km stretch of the Mustajärvi Shear Zone. The hole penetrated 90 gram-meters of gold, expressed as grade-thickness. Most of these intervals have been reported from drill holes directed to the north-northwest, perpendicular to the Mustajärvi Shear Zone, because that is an important controlling direction for gold mineralization. In several instances, FireFox geologists have noted crossing structures that also appear to host significant alteration, veining, and gold. The most recent intercepts from the East Target indicate that the cross structures may be very significant in this area and that mineralization might be thicker.
Sedimentary rocks (laminated siliciclastic rocks) and mafic volcanic or intrusions are more prevalent at the East Target than at the Central Zone or the Northeast Target. A follow-up drilling has been executed because the mineral system is shifting to the northeast.
According to Carl Löfberg, FireFox’s CEO, it is uncommon for gold exploration to encounter such thick intervals of high-quality material less than 20 meters down. Because we moved quickly to follow up on our last drill results with these several shallow drill holes, we tested our hypothesis that the mineralization in the East Target has some new controls. We anticipate reporting the outcomes of this drill program in a few weeks. If we succeed in these recent drills, we expect the newest high-quality area to increase significantly.
