Gold Standard Intersects 8.5m Of 11.16 g Au/t
VANCOUVER, BC - Gold Standard Ventures Corp. reported assay results from two core holes at the North Bullion deposit on its 100%-owned/controlled Railroad-Pinion Project in Nevada’s Carlin Trend. Both holes returned significant intercepts that expand the gold mineralization to the northwest and north. Results from RR16-01 are highlighted by 65.6m of 3.17 grams gold per tonne (g Au/t), which includes a higher grade interval of 8.5m of 11.16 g Au/t.
Jonathan Awde, CEO and Director of Gold Standard commented: “North Bullion was our first discovery on our Railroad-Pinion project and it remains potentially the most significant in the long term. We are very excited to see the results from the rest of this year’s program at North Bullion. We think we may be in the early stages of exploring one of the prolific high-grade, collapse breccia-hosted deposits on the Carlin Trend.”
North Bullion is a classic Carlin-style, high-grade deposit exhibiting all the characteristics of large, high-grade collapse breccia hosted deposits on the Carlin Trend. Unlike GSV’s Pinion and Dark Star deposits which are highly oxidized, gold-bearing rock at North Bullion is refractory in nature but the additional cost of processing this material is often offset elsewhere on the Carlin Trend by increased grade.
Exploration drilling at North Bullion ended in 2013 with very encouraging intercepts in the Lower Breccia Zone of 98.2m of 3.26 g Au/t (including 17.1m of 9.98 g Au/t) in RR13-11 and 73.5m of 3.67 g Au/t (including 12.2m of 6.93 g Au/t) in RR13-08. Subsequently, a new interpretation identified a west-northwest trend to the lower zone, higher-grade gold mineralization. Multiple data sets supported, and now confirm, this conclusion including grade x thickness contours, structure contours, gravity and CSAMT. West-northwest structural zones are an important control for gold mineralization throughout the Carlin Trend. Newmont’s Saddle (780,000 oz @ 19.6 g Au/t) and Tess (1.5 Moz @ 12.7 g Au/t) deposits occur along the west-northwest Rain fault, located just 7 km to the north of the North Bullion deposit.
The primary objective of the 2016 North Bullion drill program is to test for an extension of the Lower Breccia Zone to the west-northwest and north. A more cost-effective approach to drilling North Bullion was developed using reverse-circulation (RC) drills to complete and case holes (so-called precollars) to depths immediately above the target before switching to a core rig to complete the hole through the mineralized zone. This approach has proved effective in the 2016 drill program.
