VANCOUVER, British Columbia, Dec. 19, 2024 (GLOBE NEWSWIRE) -- VR Resources Ltd. (TSX.V: VRR, FSE: 5VR; OTCBB: VRRCF), the "Company", or “VR”, has received the final, inverted data for the state-of-the-art, 3D array DCIP survey completed last month on its Silverback copper-gold project located in Northwestern Ontario.

  • A large, high amplitude chargeability anomaly is identified in the center of the project, central to the broadest part of the main mafic - ultramafic body with nickel-chrome mineralization, as shown in Figure 1.

    • Photo 1 shows copper-gold mineralization in a sheared and silicified mafic rock from a new showing discovered in January 2023 that is in the northern part of the new chargeability anomaly. Similarly, there are fractures with remobilized moly in gabbro in the southern part of this large chargeability anomaly.

  • There are several additional chargeability anomalies to the west and northeast, also associated with edges of the mafic-ultramafic body, and anchored by north-south structures with known copper-gold mineralization.

Figure 1. Plan map of the Silverback 3D DCIP survey area with chargeability results as isoshells at 12.5 mV/V (orange) and 15 mV/V (red) with inferred shear-zones and margins of the nickel-mineralized mafic dykes and intrusions spanning the project area. The survey straddles the northern margin of the Lac des Mille Lacs greenstone belt with the Marmion batholith on a deep seated lithotectonic structures.

Initial Impressions. The dipole-dipole survey, with a 150m equant station grid array covered an area of 3,500 by 2,750 meters over the centre of the project. Firstly. All the strong chargeability anomalies correlate with the edges of the mafic-ultramafic body with copper-gold occurrences spanning some 4 km across the breadth of the property. But in addition, there is also a clear structural control to the new anomalies: the large, central anomaly is anchored by a north-south shear-zone with structural offsets evident on detailed airborne magnetic data obtained last winter, and the discreet anomalies that lie to the west occur on a west-northwest trend that is subparallel to the greenstone belt contact in the southern part of the Marmion terrane.

In summary, the new IP survey delineates chargeability anomalies at the intersection of mafic feeder dykes that are offset by sinistral, north-south faults. The new chargeability anomalies are potentially the source for remobilized and concentrated sulfide minerals on structure. Remobilized molybdenum is a crucial pathfinder metal for gold mineralization in the Hemlo gold camp, and is commonly cited as evidence for an intrusion-related source of mineralization. The molybdenite occurrence shown in Figure 1 in the southern part of the main chargeability anomaly at Silverback, and the porphyry unit with gold-bearing quartz-carbonate veins located to the west (see Photo 1 of NR24- dated October 24th) serve as important building blocks for this evolving, integrated model for a large, polymetallic copper-gold system at Silverback.
