The recently acquired Silverback project has overlapping but distinct
targets for an intrusion related copper-gold system and magmatic
nickel-copper-PGEs hosted in layered ultramafics. It straddles the Lac
de Mille Lac greenstone belt and the Marmion terrane in the central
Wabigoon Subprovince. The property was staked in 2021 after the
discovery of adjacent Ni-Cu-PGE and Cu-Au showings. Anomalous nickel
mineralization is associated with high-magnetic feeder dykes and mafic
bodies found across 3.5 km in grab samples and drill results;
remobilized copper, gold, and molybdenum mineralization has been
observed on north-south shear zones, locally hosting up to 9.5 g/t
gold and 5.6% copper. Before vending to VR, the project was
flown with airborne DIGEM and followed up with two short scout
drillholes 1km apart on strong conductors anomalies.
A two-hole, 314m maiden drill program conducted by Holbik Exploration in
spring 2024 at Silverback tested near-surface conductors derived from
the recent, 2023 DIGEM frequency-domain airborne survey targeting
sulfide mineralization below glacial till cover. Anomalous gold occurs
across 109 meters in a sericite-altered porphyry intrusion with
disseminated pyrite in Hole 2, just above the nickel and chromium
results reported on October 22nd in NR-24-22, as shown in the drill
section in linked above. Similar alteration and weak gold mineralization
is also seen 1.5 km to the east in porphyry dykes in Hole 1.
-
There are 20 one-metre samples with >10ppb gold across a 109m
interval of altered and sheared porphyry;
-
Up to 649 ppb gold in a 25cm quartz-carbonate vein with
sulfide margins;
-
The strong vein alteration with gold and disseminated pyrite is
coincident with a DIGEM conductor;
-
0.10% Ni, 0.15% Cr, 171 ppm Cu, and 86 ppm Co over 50m
starting at 160m in Hole 2, below the porphyry;
-
Ni-Cr-Co grades increase with depth towards the western margin of
a mafic dyke with a strong conductor;
-
Nickel sulfide observed in mafic feeder dyke aligns with high nickel
tenors of ~77%;
Overall, the mineralized porphyry is now the inferred source intrusion
for the widespread copper, gold, and molybdenum mineralization first
recognized at Silverback in surface samples along north-south shear
zones spanning about 3.5 km of the property, with up to 9.5 g/t gold and
5.6% copper locally (see Figure 8).
