New Core Drilling Intersects 5.3m Of 7.02g Au/T
VANCOUVER, BC - Gold Standard Ventures Corp.reported that 2016 drilling has extended the North Bullion gold system 180 meters to the north of previous drill holes on its 100%-owned/controlled Railroad-Pinion Project in Nevada's Carlin Trend.
Four more core holes were completed in the 2016 program at North Bullion. Drill hole RR16-05 returned 19.8m of 4.40 grams gold per tonne (g Au/t) which includes a higher grade interval of 5.3m of 7.02 g Au/t. This result follows RR16-01 which intersected 65.6m of 3.17 grams gold per tonne (g Au/t) including a higher grade interval of 8.5m of 11.16 g Au/t located west-northwest of previous drilling.
The primary objective of the 2016 North Bullion drill program was to test for extensions of the Lower Breccia Zone to the west-northwest and north. With RR16-01 and RR16-05, both orientations have proved to be successful. West-northwest and north-striking structural zones are an important control for gold mineralization throughout the Carlin Trend. The 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-striking Rain fault, located just 7 km to the north of the North Bullion deposit (Longo, et al., NBMG Bulletin 111, 2002). North Bullion exhibits all the classic characteristics of large, high-grade collapse breccia hosted gold deposits on the Carlin Trend. Unlike GSV's Dark Star and Pinion deposits which are highly oxidized, gold-bearing rock at North Bullion is refractory in nature but the additional cost of processing this material is commonly offset elsewhere on the Carlin Trend by increased grade.
A more cost-effective approach to drilling North Bullion was developed using reverse-circulation (RC) rigs to drill and case holes (so-called pre-collars) to depths immediately above the target before switching to a core rig to complete the hole through the mineralized zone. This approach proved effective in the 2016 drill program as the Company successfully prepared 10 pre-collars at its Railroad-Pinion Project of which 6 have been completed with core to date.
Mac Jackson, Gold Standard's Vice President of Exploration stated, "We had tremendous results at North Bullion this year, intersecting high-grade gold in both our west-northwest and north trending targets while substantially lowering our drill costs. With this isolated, high-grade intercept in RR16-05, it looks like we have found a new extension of the gold system, well north of previous drill holes. Once again, we have demonstrated the potential for a North Carlin-style big system in the Railroad-Pinion district. We are looking forward to following up on these results with a larger exploration program at North Bullion in 2017."
