    Initial Jasperoid Wash drilling campaign

Jasperoid Wash Drilling

Phase 1 and 2 drilling programs were conducted in 2017 and 2018. 

Key Highlights from recent Jasperoid Wash Drilling:

On February 21, 2019, the Company reported Phase 2 results from 19 RC holes and 2 core holes.

  • Core hole JW18-30 intersected 27.7m of 0.86 g Au/t, including 4.9m of 1.12 g Au/t and 12.2m of 1.17 g Au/t. The hole confirmed the down-dip continuity of mineralization intersected in JW18-01 (see July 26, 2018 news release). Material from this hole will be used for column leach testing.
  • Stepout hole JW18-37 intersected 25.9m of 0.69 g Au/t, including 6.1m of 1.10 g Au/t, of near-surface oxide mineralization. This intercept is approximately 80m north of drill holes JW18-26 (22.9m of 0.76 g Au/t, including 10.7m of 1.15 g Au/t) and JW18-28 (38.1m of 0.63 g Au/t, including 15.2m of 1.23 g Au/t) (see July 26, 2018 news release). These oxide intercepts begin at or near the current topographic surface.
  • JW18-29, a core twin of RC hole JW18-16 (27.4m of 0.25 g Au/t - announced on July 26, 2018), intersected 53.2m of 0.31 g Au/t in the central portion of the deposit. Oxide mineralization begins at the current topographic surface and the intercept is thicker and higher-grade than the JW18-16 intercept. Mineralized material from this hole will be used for column leach testing.
  • On the northernmost end of the deposit, stepout drill holes JW18-47 and -48 intersected oxide mineralization beginning at the current topographic surface. These intercepts extend the strike length of the deposit approximately 550m to the north of drill holes JW18-26 (22.9m of 0.76 g Au/t) and JW18-28 (38.1m of 0.63 g Au/t) where mineralization also begins at or near the current topographic surface (see July 26, 2018 news release). Mineralization remains open for additional expansion.
  • On the southern end of the deposit, drill holes JW18-38, -40, -41, -43 and -44 intersected shallow oxide gold mineralization that extends the deposit to the south and southeast. Oxide mineralization begins at or near the current topographic surface and remains open to the east and south.
  • Drilling has outlined a zone of near-surface, oxide gold mineralization measuring approximately 1,575m long (striking north-northeast) by 650m wide (east-west). The 49 holes completed in 2018 continue to establish lateral and strike continuity of the near-surface oxide mineralization which remains open in multiple directions.
  • AuCN test results indicate the significant drill intercepts are comprised of zones of both oxide and reduced mineralization. AuCN ratios are a first-pass estimate of the potential gold recovery and ratios >60% are indicative of oxide material. Further metallurgical work is required.

Drill Hole Assay Tables*


*The gold intervals reported in these assay tables are based on a 0.14 gpt Au cut-off. Weighted averaging has been used to calculate all reported intervals. The reported gold intervals may, or may not represent true thicknesses and, or widths. In general, the gold distribution within these large, complex breccia bodies tends to be irregular and will require additional drilling to establish true widths. 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 or certified reference material was inserted approximately every tenth sample. The North Dark Star core and RC samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, NV. The samples are crushed, pulverized and sample pulps are shipped to Bureau Veritas certified laboratory in Sparks, NV or Vancouver, BC. Pulps are digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30-gram split. All other elements are determined by ICP analysis. Data verification of the analytical results includes a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to insure accurate and verifiable results.
