Gold Standard Ventures Corp. (TSXV:GSV,NYSEMKT:GSV) announced assay results from hole DS15-13, which was drilled to twin reverse-circulation hole DS15-11. Both holes are located at the North Dark Star oxide gold deposit at the company’s Nevada-based Railroad-Pinion project.
Highlights for hole DS15-13 include:

  • DS15-13 intersected vertically-extensive, oxidized intercepts of 15.4m of 1.85g Au/t and 97.0m of 1.61 g Au/t, approximately 515m north of the Dark Star maiden resource, confirming the thick zone of oxidized gold mineralization originally identified by RC hole DS15-11.
  • Higher grade intervals exist within the 97.0m zone including 18.0m of 3.36g Au/t from 182.9m to 200.9m. Gold mineralization is open in multiple directions.
  • Core confirms the presence of favorable carbonate host rocks – bioclastic limestone, silty limestone and calcareous sandstone within a coarse conglomerate debris flow unit.  This Pennsylvanian-Permian unit also hosts the Dark Star deposit to the south and represents a new, unconventional host on the Carlin Trend.  Regardless of age and convention, these carbonate rocks react in a chemically similar fashion to more well-known Carlin host formations in which early stage decalcification (carbonate removal) is followed by silicification.  Rocks of similar age and composition host large, disseminated gold deposits further west in Nevada on the Getchell Trend and in the Battle Mountain district.
  • is typical of core twins of RC holes, DS15-13 intersected higher gold grades over narrower intervals.  Difficult drilling in strongly fractured rock and the presence of high gold grades appear to have resulted in the displacement of some of the gold in RC DS15-11 down the hole into the gap between 125.1 to 149.0 meters and below 246.0 meters..
  • Gold mineralization is hosted in a multi-stage breccia and is associated with limonite, decalcification, silicification, quartz stringers, drusy quartz, hematite, clay and barite.  The brecciation is more pervasive and complex than is apparent in the DS15-11 reverse-circulation cuttings.
  • Mineralization occurs within a horst (uplifted block) of permissive host rocks, in the footwall of a large-displacement normal fault.  This favorable geologic pattern is a well-documented control to gold mineralization on the Carlin Trend.

Mac Jackson, vice president of exploration at Gold Standard, commented:

The North Dark Star discovery demonstrates the ability of Gold Standard Ventures to quickly add value through exploration.  In a little over a year, we have consolidated land within the Dark Star corridor, created a new geologic model based on re-logging, released a maiden resource estimate, defined targets and completed two phases of drilling resulting in a new discovery.  The core from DS15-13 contains spectacular breccia textures and gaudy iron oxides, indicating that we are into a very strong oxidized gold system.   In 2016, we will follow up by expanding the oxide gold zone intersected in the initial discovery holes at North Dark Star.
