Silverback Project Gold Mineralized Porphyry Intrusion Discovery
VANCOUVER - VR Resources Ltd. reported on the drill program at its Silverback Project in Ontario, in follow-up to the new base metal results reported. 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. 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 margin with sulfide. The strong vein alteration with gold and disseminated pyrite is coincident with a DIGEM conductor.
This discovery of an altered, gold-bearing porphyry intrusion in Hole 002 is near a 99th percentile gold anomaly in an OGS regional lake sediment survey. 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.
CEO Justin Daley, said, "The blind discovery of a gold-mineralized porphyry intrusion at the Silverback project is significant. We have seen the high-grade potential for gold and copper in sparse outcroppings along shear zones, and we have now identified a source mineralized porphyry intrusion in two drills holes which themselves span about 1.5 km. The potential here is that the hydrothermal alteration, veining, and sulfide mineralization now evident at Silverback is commonly associated with large, intrusion-related gold deposits in Archean rocks in Ontario.
We’re excited to finalize plans for a 3D-array IP survey at Silverback in order to map chargeability and conductivity, which we now know correlates to pyrite mineralization with gold, and vector into the core of this gold system. We believe the survey will identify a central mineralized intrusion that is the source of widespread polymetallic mineralization at surface.”
