Vista Gold Corp. (NYSE American and TSX: VGZ) (“Vista” or the “Company”) is pleased to provide results from the ongoing drilling program at the Company’s 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) located in Northern Territory, Australia.

Highlights of Drill Holes VB20-005 and VB21-001 on Section 8435900 N and VB21-003 on Section 8435850 N

  • Confirmed continuity of mineralization north of the Batman deposit, with mineralization coming to surface;
  • Encountered a thicker than expected mineralized zone;
  • Demonstrated the presence of a definable, higher-grade zone within the confines of the mineralized envelope; and
  • Intersected veining, mineralogy and gold grades comparable to those found in the core zone of the Batman deposit, suggesting no material differences in metallurgical behavior.

Frederick Earnest, President and CEO of Vista, stated, “We are very encouraged by the results of our ongoing drilling program, which have intersected mineralization at approximately the predicted intervals, in all seven holes drilled to date. Furthermore, the results of the three holes announced today combined with those drilled previously on Section 8435935 N strongly support our confidence that the resources in the Batman deposit can be significantly increased just north of, and immediately adjacent to the planned Batman pit.

“Drilling in our initial program is complete. We are undertaking additional drilling and have secured a second drill rig to accelerate the next program. We plan to step out to the north to test targets and assess the continuity of mineralization from the Batman deposit toward the Golf-Tollis targets, approximately a kilometer to the north. The second drill rig is expected to be on site by early April. We look forward to discussing the results of the last hole in the original program, a step-out hole 500 meters to the north, as assay results become available in the coming weeks.”

In the fourth quarter 2020, the Company commenced an eight-hole drilling program to test the continuity of mineralization north of the Batman deposit.

Results from Hole VB20-001 were announced in December 2020 (News Release) and confirmed the existence of a mineralized zone that is believed to be a connection between the main Batman structure and the Golf-Tollis structure. Results from holes VB20-002, -003, and -004 were announced in January 2021 (News Release) and confirmed the existence of mineralization to the north of the main Batman structure. Relative to the three drill holes announced in January 2021, holes VB20-005 and VB21-001 were 35 meters south and VB21-005 was 85 meters south. These holes were drilled to confirm the continuity of both mineralization and grade in an area immediately north of and outside the limits of the proposed Batman pit.

Assay results for holes VB20-005, VB21-001and -003 are summarized below.

The following plan view (Figure 1) shows the locations of these drill holes relative to previously announced drill holes and the limits of the proposed Batman pit. Drill holes announced in January 2021 were drilled on Section 8435935 N (labeled as Section A-A’). Holes VB20-005 and VB21-001 were drilled on Section 8435900 N (labeled as Section B-B’), while hole VB21-003 was drilled on Section 8435850 N, approximately 50 meters to the south.

Data Verification and QA/QC

The sampling method and approach for the drillholes are as follows:

  • The drill core, upon removal from the core barrel, is placed into plastic core boxes;
  • The poly core boxes are transported to the sample preparation building;
  • The core is marked, geologically logged, geotechnically logged, photographed, and sawn into halves. One-half is placed into sample bags as one-meter sample lengths, and the other half retained for future reference. The only exception to this is when a portion of the remaining core has been flagged for use in the ongoing metallurgical testwork;
  • The bagged samples have sample tags placed both inside and on the outside of the sample bags. The individual samples are grouped into “lots” for submission to Northern Analytical Laboratories for preparation and analytical testing; and
  • All of this work was done under the supervision of a Vista geologist.

Processing of the core included photographing, geotechnical and geologic logging, and marking the core for sampling. The nominal sample interval was one meter. When this process was completed, the core was moved into the core cutting/storage area where it was laid out for sampling. The core was laid out using the following procedures:

  • One meter depth intervals were marked out on the core by a member of the geologic staff;
  • Core orientation (bottom of core) was marked with a solid line when at least three orientation marks aligned and used for structural measurements. When orientation marks were insufficient an estimated orientation was indicated by a dashed line;
  • Geologic logging was then done by a member of the geologic staff. Assay intervals were selected at that time and a cut line marked on the core. The standard sample interval was one meter, with a minimum of 0.2 m and a maximum of 1.2 m;
  • Blind sample numbers were then assigned based on pre-labeled sample bags. Sample intervals were then indicated in the core tray at the appropriate locations; and
  • Each core tray was photographed and restacked on pallets pending sample cutting and stored on site indefinitely.

The core was then cut using diamond saws with each interval placed in sample bags. At this time, the standards and blanks were also placed in plastic bags for inclusion in the shipment. A reference standard or a blank was inserted at a minimum ratio of 1 in 10 and at suspected high grade intervals additional blanks sample were added. Standard reference material was sourced from Ore Research & Exploration Pty Ltd and provided in 60 g sealed packets. When a sequence of five samples was completed, they were placed in a shipping bag and closed with a zip tie. All of these samples were kept in the secure area until crated for shipping.

Samples were placed in crates for shipping with 100 samples per crate (20 shipping bags). The crates were stacked outside the core shed until picked up for transport and shipped to NAL Pty. Ltd an independent, ISO 9000 certified lab, for standard fire assays. At the lab, the samples are pulverized and split down to 50-gram assay samples prior to assaying. The industry-standard 3 assay-ton fire assay is followed by an atomic absorption (AA) finish, except where results were greater than 3 g Au/tonne, and then a gravimetric finish was used to report final results.

The QP is satisfied that sample security measures meet industry standards. Statistical analysis of the various drilling populations and quality assurance/quality control (QA/QC) samples has not identified or highlighted any reasons to not accept the data as representative of the tenor and grade of the mineralization estimated at the Batman deposit.
