Dark Star Overview

The Dark Star deposit is located in the southern portion of the Railroad property. It is the first NI43-101 compliant resource hosted in Pennsylvanian rocks defined on the Carlin Trend. In June 2017, APEX Geosciences estimated an an Indicated Mineral Resource of 15.38 million tonnes grading 0.54 grams per tonne (g/t) gold (Au), totaling 265,100 ounces of gold, and an Inferred Resource of 17.05 million tonnes grading 1.31 g/t Au, totaling 715,800 ounces of gold (please see press release dated June 29, 2017).

In November 2015, GSV exploration drilling intersected 149.4 m of 1.45 g Au/t from 216.5 to 365.9 meters in DS15-10* (please see press release dated November 4, 2015) and 157 m of 1.59 g Au/t from 103.7 to 260.7 meters in DS15-11* (please see press release dated November 10, 2015). These intercepts are 515 meters to the north of the Dark Star resource and are thicker and higher grade than existing intercepts within the resource. In December of 2015, Gold Standard twinned RC hole DS15-11 with DS15-13, the first core hole into the deposit. DS15-13* intersected vertically-extensive, oxidized intercepts of 15.4 m of 1.87 g Au/t and 97.0 m of 1.56 g Au/t, confirming a thick zone of oxidized gold mineralization originally identified in RC hole DS15-11 (please see press release dated January 21, 2016).

At the beginning of the 2016 program, DS16-08* intersected a thick, vertically-extensive, oxidized intercept of 126.2m of 4.07 g Au/t approximately 100m south of discovery hole DS15-13. Most recently, DS16-03B* intersected a thick, vertically-extensive, oxidized intercept of 101.2m of 1.54 g Au/t approximately 120m south of DS16-08 and 220m south of discovery hole DS15-13. The 2016 program succesfully connected both the Main and North dark Star deposits and discovered a western extension of the high grade Dark Star mineralization with exciting implications for further growth of the system. The deposit now has a strike length of 1.3km with exploration potential remaining open in multiple directions. The company has announced a 2017 drill program of 24,000m at Dark Star and the 7km long Dark Star Corridor

Dark Star occurs in a 400-600 m wide, 7 km long, linear, north trending horst.  The east-bounding fault is a north-northeast-striking, 75 degree east-dipping large displacement normal fault with Eocene Elko Formation sedimentary rocks and Indian Well Formation volcanic rocks in the hanging wall. The west bounding fault is a north-northeast striking, 65 degree west-dipping normal fault that has less offset, dropping the host section 100 meters in that direction. Historic drill intercepts, alteration, and geochemical samples indicate the horst is prospective along its defined length.
