The company found 4.1 grams of gold per ton (g/t Au) and 311 g/t silver (Ag) in a surface grab sample of quartz-adularia altered tuff with a pervasive clay overprint from within the 2-by-3 kilometer potassium anomaly at Amsel.
The company has increased the size of the Amsel property three times, which now consists of 66 claims covering 1,363 acres and the entire 2-by-3 km quartz-adularia alteration cap.
“Simply put, we were not expecting the concentration of gold and silver mineralization reported here in a rock sample with minimal visible quartz veining, and located on the northern periphery of our integrated target at Amsel based on an array of integrated mapping, geochemical and geophysical surveys,” CEO Michael Gunning said in a statement.
“Gold and silver typically correlate with visible pyrite in banded quartz-adularia veins and vein breccia with both open space and colloform texture, … yet the high silver and gold grade reported here are from a sample of tuff with pervasive, low temperature clay alteration with minimal veining.”
The sample is one of 135 grid samples collected systematically for alteration mineral mapping, as opposed to visible mineralization, the company said. The sample grid covers the 1.8-by-2.2 km core of the larger, 2-by-3 km potassium anomaly, and the samples were used for short-wave and long-wave infrared spectral imaging to identify and map alteration minerals. The hand samples were then submitted to ALS laboratories in Reno this winter for geochemical analysis.
VR Resources has completed and filed an independent NI 43-101 Technical Report on the Amsel property. It incorporates all data collected during 2018 and 2019, and recommends first-pass drilling of the untested target at Amsel, the company said.
“High grades in silver and gold are evident across the entire breadth of the 2 x 3 km quartz-adularia alteration cap at Amsel, and more importantly in a broad range of alteration and mineralization textures in host rhyolite tuff,” Gunning said. “Our actions to increase the size of the property, again, and complete an independent, NI 43-101 Technical Report on the property speak to our conviction on the potential of Amsel.”
The large and integrated anomaly for a low-sulfidation epithermal gold-silver deposit related to pyritic, quartz-adularia vein stockworks and breccia under the southwest flank of the hill at Amsel is previously unexplored, the company said.
The Big Ten epithermal gold property in the Walker Lane belt of Nevada comprises seven properties along a district-scale 20 km trend and multiple claims. The properties are the Hat Peak, Kano Amsel, Danbo, Little Joe, Clipper and Fischer properties. There is easy access to power and rail and an international airport in Reno.
Elsewhere, the company owns the Bonita project in Nevada, a large porphyry copper-gold system discovered by VR with a 5-by-7 km footprint and five to six specific targets.
In Ontario, VR owns the previously unexplored Ranoke copper, gold project, which was staked by the firm in 2019 and is a large-scale iron oxide copper-gold target.
