Gold Standard Ventures Provides Dark Star Exploration Update
41.2 meters of 3.06 g Au/t sulphide mineralization intersected directly below Dark Star North pit boundary
VANCOUVER, British Columbia, Sept. 13, 2021 (GLOBE NEWSWIRE) -- Gold Standard Ventures Corp. (NYSE AMERICAN: GSV) (TSX: GSV) (“Gold Standard” or the “Company”) today announced drill results from 20 reverse circulation (“RC”) drill holes at the Dark Star gold deposit.

Key Highlights:
-
Drill holes DR21-14 and DR21-15 were completed at Dark Star North to support conversion of certain Inferred resources to Measured and Indicated resources for inclusion in the mine plan.
-
Drill hole DR21-15 intersected an interval of 41.2 meters of 3.06 g Au/t sulphide mineralization directly below the oxide pit boundary.
Jason Attew, President and CEO, commented, “Dark Star drilling was focused on development holes for 2021 and the drill program accomplished the desired objectives. The two deeper drill holes at Dark Star North both intersected mineralization below the pre-feasibility study pit boundary, highlighting the exploration potential at depth at Dark Star.”
Development Highlights:
-
Drill holes DR21-11, DR21-12, and DR21-17 through DR21-20 were completed at Dark Star Main as in-fill drill holes and intersected ore grade mineralization similar to holes previously drilled at Dark Star Main and indicate that the ore body is still open to the south.
-
Drill holes DR21-01 through DR21-09 were completed on a zone of gravels east of the Dark Star Main deposit. The gold grades intersected represent an eroded portion of the Dark Star Main deposit and are currently being evaluated for utilization / suitability as over-liner on the proposed heap leach pad.

Note: Gold intervals reported in this table were calculated using a 0.14 g Au/t cutoff for oxide mineralization and a 1.0 g Au/t cutoff for sulphide mineralization. Weighted averaging has been used to calculate all reported intervals. True widths are estimated at 70-90% of drilled thicknesses. Drill holes presented in this table have a gold equivalent gram-meter product greater than 10.
Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance
All Gold Standard sampling was conducted under the supervision of the Company’s senior geologists and the chain of custody from the project to the sample preparation facility was continuously monitored. A blank, certified reference material, or rig duplicate was inserted approximately every tenth sample. Samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in either Sparks, NV or Hermosillo, Mexico where they were crushed and pulverized. Resulting sample pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy finish on a 30-gram split. Over limit gold assays were determined using a fire assay fusion with a gravimetric finish on a 30-gram split. All other elements were determined by ICP in Vancouver, B.C. Data verification of the analytical results included a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to insure accurate and verifiable results.
