Canadian-listed gold explorer FireFox Gold reported a 6.15-metre intercept grading 4.10 grams per tonne of gold at its Mustajärvi project in Finnish Lapland, extending gold-bearing drillholes across the prospect’s main shear zone to more than 2.5 kilometres. The company said the results indicate mineralisation beyond established lodes, but do not establish a continuous economic deposit.
Drilling tests targets beyond established zones
Reported on November 5, drillhole 26MJ057 at the Gabbro Target intersected the gold over a main interval beginning at an approximate downhole depth of 224 metres. Within it, a 1.05-metre interval graded 14.65 grams per tonne. The Gabbro Target lies west of Mustajärvi’s principal mineralised areas.
Geophysical work identified a conductor at Gabbro and was designed to locate conductive structures outside better-tested gold zones. Hole 26MJ057 followed up that target; another hole there intersected narrower gold-bearing zones, for which no assay figures were provided. Farther north, two holes tested the previously undrilled Triangle Target structure.
At Triangle, hole 26MJ037 intersected 2.7 metres grading 2.15 grams per tonne, including 0.95 metres at 3.58 grams per tonne. Hole 26MJ036 intersected 1 metre grading 2.8 grams per tonne.
Further work needed to assess the wider system
FireFox is using fixed-loop and borehole electromagnetic surveys to guide follow-up drilling, and further Mustajärvi targets remain to be tested. Cumulative drilling, including the recent holes, has reached about 31,070 metres.
The new intersections expand the exploration footprint and help guide target selection, but are not a resource addition or a commercial discovery on their own. Additional drilling, geological modelling and metallurgical work are needed before the economic potential of the wider system can be assessed.
Mustajärvi is in the mineral-rich Lapland region, where established mining infrastructure and gold exploration activity have attracted international investment. FireFox’s central technical question is whether scattered mineralised zones can be connected into a resource of sufficient scale and grade to support a potential mine-development case.
