Vr Resources Limited Completes 2,892 Ft Drill Hole and Reports Polyphase Vein Intersection At New Boston Moly-Tungsten-Copper-Silver Porphyry Project in Nevada
VR Resources Limited has completed a 2,892 ft (881m) hole through continuous veining with sulfide at Jeep Mine on its New Boston moly-tungsten-copper-silver skarn and porphyry system located just off Highway 95 in west-central Nevada. Data and assays are pending from hyperspectral scanning and continuous geochemical sampling of the entire drill-hole intersection which are in progress at laboratories in Reno, Nevada. The proximal, high temperature alteration and mineral zone at Jeep Mine is visible in front of the drill in the photo. The DCIP geophysical plan map and profile illustrate the specific, and integrated geophysical target for hole NB26-003 within the larger alteration and vein zone. Drill hole NB26-003 achieved the primary objective of the program, and was longer than anticipated because of the veined and mineralized nature of the core. Further drilling will await integration of all geochemical data from this long vein intersection into the Company’s expansive project data base developed over the past seven years. There are eight approved sites for drilling on the Company’s current NOI drill permit. Data from NB26-003 will allow prioritization of the various permitted drill sites for further drilling within the large-footprint alteration, vein, sulfide and intrusive center that is now evident in three dimensions at Jeep Mine. The vein and sulfide intersection across 2,892 ft (881 m) of drill core in NB26-003 has confirmed the co-spatial, conductivity-chargeability anomaly in the Company’s 2023, 3D-array DCIP geophysical survey as the inferred sulfide center of the large-footprint polymetallic skarn and porphyry system exposed on surface at New Boston. Some initial take-aways from NB26-003 include: Continuity. Polyphase quartz veins with vein and disseminated sulfide logged in all core boxes across the 2,892 ft (881 m) intersection, from top to bottom of the hole; Breadth. NB26-003 did not drill through the target. The sub-vertical hole became unstable and was terminated at 2,892 ft, still in polyphase veins with sulfide in limestone completely recrystallized to marble and dolomitized marble, with clay-altered and sulfide-bearing porphyry intrusions; Intensity. There is no unaltered drill core. High temperature garnet skarn replacement and marbelization of limestone occurs throughout the hole. Hydrothermal alteration with vein and disseminated sulfide is logged in all rock types from top to bottom of the hole, including limestone, siltstone, and all intrusive porphyry phases as well; Energy. Vein geometries include: sheeted (parallel to bedding); sinuous/ptygmatic; stockwork; conjugate; planar crack-seal, and; vein breccia. Veins occur at all angles to core axis throughout the 2,892 ft intersection, from top to bottom of the hole; Polymetallic. Surface geochemistry at the drill collar site demonstrates moly, tungsten, copper and silver mineralization present in quartz-garnet veins in grey limestone recrystallized to marble. Sulfide mineral assemblages including pyrite, chalcopyrite and molybdenite in varying proportions and textures are logged in virtually every core box throughout the 2,892 ft hole, in veins with and without quartz, in vein breccia, and as disseminations; Source. There are numerous porphyry intrusive phases throughout the hole, themselves with quartz veins and vein and disseminated sulfide. There is more diversity in intrusive phases than is mapped on surface; they are the inferred driver of the expansive mineralized vein system exposed on surface over an east-west strike of 6,900 ft (2.1 km) at New Boston. The drill target is the result of 3D-array DCIP geophysical technology not available during porphyry exploration at New Boston from the mid 1960’s through late 1970’s. The IP-conductivity anomaly at NB26-003 is previously untested; this is the only known deep drill hole into the southern flank of the Jeep Mine skarn and porphyry center. The Company will dedicate resources to running the entire hole through the LWIR (long wavelength) and SWIR (short wavelength) hyperspectral mineral scanning at TerraCore Geospectral Imaging laboratories in Reno in order to map alteration minerals and identify alteration zonation across 2,892 ft of drill core. Also, high resolution, 8K photography of the entire drill hole will facilitate detailed mapping of complex vein geometries throughout the intersection. The Company will dedicate resources to geochemical techniques at ALS Global laboratories, also in Reno, which utilize digestion by sodium peroxide fusion in order to optimize detection of base metals and trace elements, especially for tungsten and molybdenum which are hosted in refractory minerals. New Boston has a mineral system of scale, location for infrastructure, jurisdictional history and pedigree in Nevada, and polymetallic composition all on its side to play into the current push towards domestic critical metal supply and resilience in North America. View east at Jeep Mine from the Blue Ribbon skarns located to the west, at the western end of the 3-4 km skarn and porphyry system at New Boston. The drill is visible in the left middle-ground, on the northern flank of the Jeep Mine hill where veins at surface contain moly, tungsten, copper and silver mineralization. Drill hole NB26-003 was inclined steeply to the south (towards the right in this photo), and intersected sulfide-bearing stockwork veining for 2,892 ft, across and down into the large, red-brown alteration zone that is clearly visible to the right of the drill in this photo. The drill hole tests the new, coincident conductivity and IP chargeability anomalies shown in profile, which plunge steeply across the country rock of north-dipping limestone and siltstone dipping from right to left in this photo, with sheeted and discordant quartz monzonite dykes themselves with quartz veins and sulfide.
