FireFox Gold, a Canadian-listed gold exploration company, reported on November 5 a 6.15-metre intercept grading 4.10 grams per tonne of gold at the Gabbro Target of its Mustajärvi project in Finnish Lapland. The company said gold-bearing drillholes across the prospect’s main shear zone now extend for more than 2.5 kilometres.
Hole 26MJ057 returned the main intercept from a downhole depth of approximately 224 metres. Within it, a higher-grade interval measured 1.05 metres at 14.65 grams per tonne. The Gabbro Target lies west of Mustajärvi’s principal mineralised areas.
Geophysical work identified a conductor before the Gabbro drilling and was designed to locate conductive structures outside the better-tested gold zones. Another hole at the target intersected narrower gold-bearing zones, but FireFox Gold provided no grades or widths for those intervals.
The company is using fixed-loop and borehole electromagnetic surveys to guide follow-up drilling, with further targets still to be tested. The Gabbro result followed the geophysical identification of the conductor.
Triangle Target and project drilling
Two reconnaissance holes tested the previously undrilled Triangle Target, farther north. Hole 26MJ037 intersected 2.7 metres grading 2.15 grams per tonne, including 0.95 metres at 3.58 grams per tonne; hole 26MJ036 returned 1 metre at 2.8 grams per tonne.
Including the recent holes, cumulative drilling at Mustajärvi reached about 31,070 metres, according to the company. The results indicate gold mineralisation beyond established lodes, but the intersections alone do not establish a continuous economic deposit. They expand the exploration footprint and aid target selection, but are not a resource addition or a commercial discovery on their own.
Further work needed to assess economic potential
Mustajärvi is in Lapland, a mineral-rich region with developed mining infrastructure and gold exploration activity that has attracted international investment. FireFox Gold’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.
Further drilling, geological modelling and metallurgical work are needed before the economic potential of the wider system can be assessed.
