Gold Standard Ventures Corp. reported favorable results from a check assay program for the North and Main Dark Star deposits on its 100%-owned/controlled Railroad-Pinion Project in Nevada's Carlin Trend. A comprehensive assay check (umpire) program was completed by ALS Chemex on original drill hole sample pulps from the company's 2015 and 2016 drilling at the Main and North Dark Star deposits which had reported values at or above the 0.14 g Au/t cut-off grade established in the NI 43-101 resource estimate. In total, ALS assayed 1,838 drill sample pulps from 37 drill holes distributed throughout the North and Main Dark Star deposits using the Au-AA23 method. ALS assays confirmed, verified and, in certain instances, increased the gold grade from the original Bureau Veritas gold fire assays. Additionally, metallurgical core holes DS16-17 and DS16-20 were completed at the Main Dark Star deposit to provide samples for column leach testing.
