Wolfden Resources Corporation to provide the exploration results from its fall/winter exploration program at its Big Silver Project in Maine, USA. Drilling included 8 holes in some 1,750 metres across serval different target types. Part of the objective of the program was to determine the potential for expansion of the known mineralization to a depth of 400 metres, well beyond the historical work of 125 to 150 metres.

The Company holds the mineral rights to a land package of over 800 acres and has reasonable expenditure commitments to maintain and complete a 100% interest in the Project. The core of the Big Silver Project is a 1,500 m by 2,000 m area of historic silver, zinc, lead, copper and gold mineralization with historic drill intercepts including 530.2 g/t AgEq over 15.2 metres and 14.63 g/t Au and 1.07% Cu over 7.0 metres. The high precious-metal polymetallic mineralization is hosted by sediments, mafic volcanics and hydrothermal breccias.

Wolfden's objective was to confirm and expand on the historic results utilizing several techniques including drilling, soil sampling, an induced polarization and ground magnetic geophysical surveys. Wolfden's work has defined and expanded the footprint of the mineralized zones with the new data providing context and prioritized target areas for future drill programs. The silver, zinc, lead, copper and gold zones are hosted by variably altered mafic volcanic, diorite, siltstone to sandstone, conglomerate, siliceous sinter and hydrothermal breccia. Sulphide minerals comprise disseminated to veinlet to blebby sphalerite, galena, tetrahedrite, chalcopyrite and arsenopyrite.

Alteration comprises variable amounts of milky silicification, bleaching, sericitization, spillitization, pervasive to veinlet style calcite, dolomite and rhodonite (manganese carbonates) and barite veins. Soils are pervasively enriched in zinc (to 7,384 ppm), lead (to 5,232 ppm), manganese (to 8,870 ppm) and silver (to 20.4 g/t Ag) with local enrichments of copper (to 3,473 ppm), arsenic (to 769 ppm) and gold (to 484 ppb). Zinc- and silver-in-soil anomalies are the largest with the northwest trending, combined zinc- (approximately >500 ppm) and silver-in-soil anomaly (>1 g/t silver) extending for approximately 1,700 metres by up to 600 metres wide.

The >1 g/t silver-in-soil anomaly (eastern northwest-trending soil anomaly lobe), which partially to totally overlaps a zinc-in-soil anomaly at its western side occurs as a 2,250 metre by up to 500 metre anomaly. These anomalous soil zones not only overlay known zones, but also show connections between the historic zones and indicate extensions along strike. Ground magnetic high anomalies correlate with mafic volcanics and diorite bodies with the magnetically low areas correlating with sediments, siliceous sinter and altered volcanic rocks.

Mineralized zones often occur at the contact between the magnetic highs and magnetic lows. Induced polarization (IP) chargeability highs and resistivity high edges correlate quite well with the known mineralized zones and suggest additional targets, sometimes with coincident anomalous soil samples. These steeply to moderately dipping anomalies generally persist to the survey depth of 400 metres and also show up as buried targets.

There is significant scope to test, extensions of known zones to depth and along strike and to test new, sub-cropping to buried targets. In 2021, 8 holes comprising 1,751.5 metres were drilled with 4 holes testing the Ag-Zn-Pb Main Zone and 4 holes testing geochemical targets in the M2 Zone area. Significant amounts of Ag-rich mineralization was intersected in the Main Zone with holes returning to 217.1 g/t AgEq over 42.5 metres in hole PB21-03 with individual samples returning 978.0 g/t AqEq over 0.7 metres in hole PB21-05.

Sphalerite mineralization was obvious in all but the first hole drill. Galena often occurred with the sphalerite and tetrahedrite (silver-bearing mineral) was only observed at the Main Zone. Mineralization occurs as disseminations, fracture-fill, veinlets and clots and is most pervasive in coarse sandstone and conglomerates.
