Exploration holes intersect 30.5m of 0.78 g Au/t, including 7.6m of 1.58 g Au/t and 24.3m of 0.73 g Au/t, including 6.1m of 1.26 g Au/t; Surface channel sample results include 24.0m of 0.97 g Au/t and 12.0m of 7.05 g Au/t


Gold Standard Ventures Corp. (TSX: GSV) (NYSE AMERICAN: GSV) reported that 10 exploration reverse-circulation holes drilled at the LT oxide gold discovery have confirmed its potential to make an important contribution to feasibility mine plans at Gold Standard’s 100%-owned/controlled Railroad-Pinion Project in Nevada’s Carlin Trend (see attached drill hole location map: LT Drill Hole Location Map 10/29/2020 and significant drill hole summary: LT Significant Intercept Table 10/29/2020). Objectives of the drilling included testing structural and stratigraphic targets to the north and south of LT19-02, a 2019 RC hole that intersected 12.2m of 1.58 g Au/t (see November 12, 2019 news release).


A planned total of 1,324.4m of drilling in 10 RC holes has been completed year to date. Oxide results include 30.5m of 0.78 g Au/t, including 7.6m of 1.58 g Au/t in hole LT20-08; 24.3m of 0.73 g Au/t, including 6.1m of 1.26 g Au/t in LT20-01; 15.2m of 0.96 g Au/t in LT20-02; and 30.5m of 0.39 g Au/t in LT20-03. These oxide intercepts begin at or close to the current topographic surface, they establish strike and downdip continuity to mineralization and are open in multiple directions.


Jonathan Awde, CEO and Director of Gold Standard commented: “The LT target is opening up into a valuable deposit which has the potential to add oxide resources to our Feasibility mine plans now in progress. These results also demonstrate that while Railroad-Pinion is in an advanced stage of development, it continues to offer exceptional near-surface oxide exploration opportunities.”


Key Highlights from LT:  


  • Inclined drill holes LT20-01, -02 and -08 were collared from the same drill site approximately 55m north of discovery hole LT19-02. The down-dip test in LT20-01, intersected 25.9m of 0.79 g Au/t, including 6.1m of 1.47 g Au/t; a strike test to the northeast in LT20-08 intersected 30.5m of 0.78 g Au/t, including 7.6m of 1.58 g Au/t; and the up-dip test in LT20-02 intersected 15.2m of 0.97 g Au/t. Oxide mineralization in these holes begins at the current topographic surface.  
  • LT20-03, an inclined RC hole approximately 77m south of LT19-02, intersected 30.5m of 0.39 g Au/t of near-surface, oxidized mineralization.
  • Surface mapping and channel sampling was conducted in 2020 to better understand the controls of LT mineralization. To date, 252 three-meter channel samples were collected with individual assay values ranging from 0.001 to 11.9 g Au/t. Continuous channel samples identified two significant zones of oxide mineralization: 1) a 24m-wide zone averaging 0.97 g Au/t on the north end of the current drill pattern, and 2) a 12m-wide zone averaging 7.05 g Au/t on the south end which remains untested by drilling. The southern zone is associated with a northeast-striking fault zone. The channel sampling program further refines the select rock chip sampling program from 2018. Results from the earlier program returned assay values ranging from <0.005 to 12.90 g Au/t, and included individual rock samples of 12.90 g Au/t, 11.20 g Au/t, 6.65 g Au/t and 4.50 g Au/t collected from surface outcrops over a 400m by 200m area (October 11, 2018 press release).  
  • Cyanide solubility assays average 82.7% for the reported significant intercepts. Cyanide solubility assays > 60% are considered oxide for Carlin-type gold systems.
  • Gold mineralization is hosted in silicified, iron oxide (limonite, goethite, hematite) bearing breccia in the hanging wall of a north-striking quartz feldspar porphyry dike.   All of Gold Standard’s previous discoveries (e.g. Dark Star, Pinion, North Bullion, Jasperoid Wash and Dixie) are localized in dike-filled fault corridors, which are ideal structural locations for the development of gold systems.
  • These results expand upon and demonstrate continuity of oxide gold mineralization along a strike length of approximately 200m. Oxide mineralization is open in multiple directions.   LT is a high value oxide target that will receive additional exploration focus in 2021.


LT drill results are as follows:


Drill Hole Method Azimuth Incl. TD (m) Intercept (m) Thickness (m) Grade (g Au/t)
LT20-01 RC 090 -70 172.2 0-24.3 24.3 0.73
Including 18.3-24.4 6.1 1.26

LT20-06 RC 090 -55 91.4 0-4.6 4.6 0.27
          60.9-64.0 3.1 0.19
LT20-07 RC 090 -70 153.9 7.6-13.7 6.1 0.15
LT20-08 RC 050 -55 178.3 0-30.5 30.5 0.78
Including 12.2-19.8 7.6 1.58
LT20-09 RC 065 -55 152.4 0-1.5 1.5 0.54
LT20-10 RC 090 -70 166.1 No assays >0.14 g Au/t


Gold intervals reported in this table were calculated using a 0.14 g Au/t cutoff for oxide mineralization. Weighted averaging has been used to calculate all reported intervals. True widths are estimated at 70-90% of drilled thicknesses.


Don Harris, Gold Standard’s General Manager commented: “The Gold Standard Ventures exploration team focus has been to explore for oxide gold deposits on the greater Railroad-Pinion land holdings that will add value to the current prefeasibility study mine plan. LT was elevated to a high priority target based on select high grade (4.5-12.9 g Au/t) rock chip results in late 2018 and initial drilling in 2019 (12.2m of 1.58 g Au/t in LT19-02). The 2020 drilling and surface channel sampling confirms that LT is a developing project, with the right characteristics of lateral continuity, oxide cyanide solubility assays, and proximity to the Pinion deposit. As presently defined, the LT deposit is located approximately 3 km north northwest of the Pinion oxide gold reserve and has potential to add to the overall gold reserve plan in the long term. The team is excited about the project and will continue further exploration in 2021.”


Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance


All sampling was conducted under the supervision of the Company’s project 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. The samples were shipped to Paragon Geochemical’s certified laboratory in Sparks, NV where they were crushed and pulverized. Resulting sample pulps were digested and analyzed for gold using fire assay fusion and an ICP-OES finish on a 30-gram split. All other elements were determined by ICP analysis. Data verification of the analytical results included a statistical analysis of the standards, blanks and duplicates that must pass certain parameters for acceptance to insure accurate and verifiable results.


Drill hole deviation was measured by gyroscopic down hole surveys that were completed on all holes by International Directional Services of Elko, NV. Final drill collar locations are surveyed by differential GPS by Apex Surveying, LLC of Spring Creek, Nevada.
