The Big Creek property was staked directly by the Company in the summer of 2017, to build on its copper portfolio and strategy in Nevada.
The staking of the Big Creek property is the result of the Company’s evolving understanding of the geology and exploration potential of northwestern Nevada based on its three years of exploration at the Bonita Property, located just 75 kilometres to the south (see Location Map on Satellite Image below). Upon acquisition and evaluation of satellite-based ASTER mineral reflectance data, the Company correlated a mineral alteration anomaly to a hydrothermally altered, veined and brecciated granite stock and staked the Big Creek property.
The property is little explored because of its location outside of Nevada’s established copper and gold mineral deposit belts. VR will evaluate Big Creek under the filter of current porphyry copper-moly’ mineral deposit models for the western US.
The Big Creek property is located in Humboldt County in northwestern Nevada, USA. It is on the eastern flank of the Pine Forest Range, due north across the Black Rock desert from the Company’s Bonita property. There is immediate and direct road access to the property on gravel roads connected to Highway 140, which provides direct access to the nearby town of Winnemucca.
The Big Creek Stock itself is at the immediate western edge of the Quinn River valley, which drains southwesterly into the Black Rock Desert. Topography is rugged. Elevation gain from the Big Creek stock to Bishop Peak atop the Pine Forest Range flanking the valley floor is approximately 2,500 feet.
The Pine Forest Range which forms the western flank of the Quinn Valley at Big Creek is a grassy rangeland with scattered sage at lower elevations. There is no pine or juniper. Climate is semi-arid to arid, with hot dry summers and cold dry winters.
Big Creek was staked directly by VR in June, 2017 (see News Release dated June 27, 2017). It consists of 30 claims in one contiguous block covering 620 acres (250 hectares). It is owned 100%, registered to VR’s wholly-owned and Nevada-registered US subsidiary Renntiger Resources USA Ltd. There are no associated royalties, or joint venture or carried interests.
The property is located on land administered by the federal Bureau of Land Management (BLM). There are no state or federal land use designations, or privately-owned land, impeding access to the property, nor is the property within the BLM’s broadly defined area of sage grouse protection.
A fixed wing airborne Hyperspectral survey (HSI) was completed over the Big Creek property in September, 2017, by SpecTIR LLC based out of Reno, Nevada. Approximately 70 square kilometres of data were acquired with a nominal ground resolution of 2 meters. The Dual system acquired 360 spectral bands between 400 and 2450 nanometers (nm) on 18 flight lines covering the survey area. Alteration minerals identified from the Level III Analysis of data outline argillic and phyllic alteration facies at the Big Creek Stock, which have been confirmed by follow-up mapping and sampling by VR (see Satellite Image below)
Surface exploration which followed the airborne Hyperspectral survey includes:
- Select rock samples (6) from hydrothermally altered granite and surrounding country rock of hornfelsed and veined volcanics and sediments; and
- Two orthogonal soil transects on 50 m stations for 60 samples in total.
A total of 19 rock samples were collected during detailed mapping of quartz vein sets in the altered granite, in follow-up to the Hyperspectral survey.
The Company will evaluate the use of geophysics in 2018 to map the Big Creek stock sub-surface and explore for porphyry style alteration facies and copper-moly’ mineralization.
