Silverback

The Silverback project features overlapping yet distinct targets for an orogenic intrusion-related shear zone hosted copper-gold-silver system and magmatic nickel-copper hosted in layered mafic-ultramafic intrusion spanning the property.

Spanning the northern margin of the Lac de Mille Lacs greenstone belt and the Marmion terrane in the central Wabigoon Subprovince, the property was staked in 2021 following the discovery of adjacent Ni-Cr-Co and Cu-Au showings. Anomalous nickel mineralization has been identified in high-magnetic feeder dykes and mafic bodies across a 3.5 km area, with remobilized copper, gold, and molybdenum mineralization observed along northeasterly shear zones, locally hosting up to 9.5 g/t gold and 5.6% copper in outcrop.

The presence of molybdenite on fractures reinforces an intrusive source for copper and gold mineralization at Silverback, yet also speaks to the temperature and intensity of orogenic fluid flow carrying these metals into shear-zone structures. Molybdenum, a critical pathfinder in the Hemlo gold camp, is typically found near the strongest gold mineralization, especially where overprinted by later sericite alteration and quartz-carbonate veining.

In late November 2024, a detailed 3D array DCIP geophysics survey was completed, successfully delineating three large near-surface IP anomalies that correlate with previously identified conductivity zones. These IP and Conductivity anomalies are now the focus of our 2025 drill program, which aims to test these high-priority areas for mineralization.

The two-hole, 314m maiden drill program conducted by Holbik Exploration in the spring of 2024 tested near-surface conductors derived from the 2023 DIGEM frequency-domain airborne survey. Notable results include anomalous gold across 109 meters in a sericite-altered porphyry intrusion with disseminated pyrite in Hole 2, alongside nickel and chromium mineralization in the adjacent gabbroic mafic-ultramafic dyke, as described in more detail in News Release NR24-23 dated October 24, 2024.

The mineralized porphyry is inferred source intrusion for the widespread copper, gold, and molybdenum mineralization first identified at Silverback, spanning approximately 3.5 km of the property. Gold mineralization on the project is associated with shearing within both the feldspar porphyry, nickel-rich gabbro, and mafic volcanics.

Target Area 1 – Central Zone (CZ)

  • The largest and highest amplitude IP anomaly is 1.2 km long in the center of the project area and follows the north-south trending structural break that is evident in magnetic data. This structure is also associated with outcrops of sheared gabbro with high grade copper-gold mineralization, and with the occurrence of molybdenite on fractures.
  • The IP anomaly comes to surface along a parallel trend of shearing, approximately 300 meters east of the main showing in an area of glacial cover.
  • The magnetic response of the east-west trending mafic body forms a trough across the IP anomaly, possibly due to demagnetization from hydrothermal alteration along the Central Zone structure.
  • To the north, beyond the 1,200-meter-long IP anomaly, the Central Zone structure has associated near-surface DIGEM conductivity anomalies, potentially caused by clay alteration, as observed in Hole 002 last year.

Drilling has confirmed a dominant northeast-trending shear system, with north-northeast splays, consistent with the broader regional deformation model. These structures correlate with DIGHEM conductors and high-amplitude chargeability anomalies, reinforcing their significance as potential gold-bearing corridors. The ongoing exploration program aims to further delineate the influence of these regional-scale shear zones on mineralization across the property.

The Silverback property is situated on the west side of Lac des Mille Lacs, in the Bedivere Lake and Boot Bay areas, approximately 120 km northwest of Thunder Bay, Ontario and 62 km northeast of Atikokan. Year round access to the claim group is possible on logging roads from TransCanada Hwy 17 and Hwy 11, reaching the centre of the property.

The Silverback property straddles the Lac de Mille Lacs greenstone belt and the Marmion terrain within the central Wabigoon Subprovince where Denver Stone of the OGS mapped a series of late mafic-ultramafic intrusions in both the Lac de Mille Lac greenstone belt and the tonalitic Marmion batholith to the north.

The Marmion Shear Zone (MSZ) is a major regional structural feature within the Marmion Terrane, 50km west of Silverback, and part of the western Wabigoon Subprovince of the Superior Craton. This northeast-trending deformation zone is a key control on gold mineralization in the region, hosting several past-producing and active gold projects. The MSZ represents a deep-seated, long-lived crustal structure that has undergone multiple episodes of deformation, reactivation, and mineralization.

The structural framework of the Marmion Terrane is dominated by northeast-trending shear zones, interpreted as splays off the MSZ. These secondary structures, often associated with major rheological contrasts between intrusive and metavolcanic/metasedimentary units, serve as conduits for hydrothermal fluid flow and gold deposition. The gold-bearing systems in the region are typically hosted within sheared granodioritic plutons, mafic metavolcanics, and late-stage quartz-feldspar porphyries, with extensive quartz-carbonate veining, silica-sericite-chlorite alteration, and disseminated sulfides.

The MSZ and its associated northeast-oriented structural corridors are well-documented hosts for gold mineralization, including the multi-million-ounce Hammond Reef deposit, located within the Marmion Terrane. Similar structural settings extend across Northwestern Ontario, linking gold deposits along the western Wabigoon Subprovince.

The mafic-ultramafic intrusions are locally coarse-grained varitextured gabbro and hornblendite with discordant dikes of peridotitic to pyroxenitic composition. The dikes strike northerly and northeasterly and attain a width of up to 100 m where exposed on islands in Lac des Mille Lacs north of Bolton Bay.

The mafic to ultramafic intrusions in the Lac des Mille Lacs area are geologically related to the Quetico suite, a series of late-stage intrusions that extend over 200 km from the Minnesota border to north of Thunder Bay. These intrusions cut through sedimentary sequences and plutonic rocks of the Quetico and southern Wabigoon subprovinces. The Quetico suite is considered a continuation of the Lac des Iles suite, located ~100 km north of Thunder Bay. Some intrusions within the Lac des Iles suite, such as the Tib and Mine Block intrusions, have been dated to 2686–2689 Ma.

Silverback is a large property. It consists of 86 mineral claims in 1 contiguous block covering 4,760 hectares in an area approximately 10 x 5 km in size.

The property is located on provincial crown land, with mineral rights administered by the provincial Ontario Ministry of Mines. There are no annual lease payments, but the MNDM requires certain annual exploration expenditures and reporting (ie. mineral assessment reports) in order to maintain a mineral claim in good standing. The property falls within the traditional territories of the Lac des Mille Lac First Nation.

The property is owned 100% by VR Resources. There is an industry-standard royalty attached to the property, including a buy-back provision to VR.
