Vista Gold Drilling Confirms Adjacent Mineralized Zone
at the Mt Todd Gold Project
Denver, Colorado, December 14, 2020 – Vista Gold Corp. (NYSE American and TSX: VGZ) (“Vista” or the
“Company”) is pleased to provide initial drill 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.
In late October, the Company commenced an eight-hole proof of concepts drilling program to test targets known as
the Batman Hanging Wall Lode and the Batman North Extension. The goal of the program is to confirm the existence
of higher-grade mineralization with vertical and lateral continuity within and immediately adjacent to the planned
Batman pit. The first hole (VB20-001) targeted the Batman Hanging Wall Lode to the east of the main Batman
structure. The remaining holes will target the Batman North Extension, where drilling is progressing.
Hole VB20-001 Highlights
Confirmed the existence of a mineralized zone that is believed to be a connection between the main Batman
structure and the Golf-Tollis structure;
Intersected the mineralized zone as projected and found the zone to be thicker than previously expected
aggregating to 60 meters of 0.72 grams of Au/ton that contained three higher grade intervals; and
Demonstrated the presence of potentially higher grade material within the mineralized zone with a single
one-meter assay of 7.79 grams of Au/tonne.
Frederick Earnest, President and CEO of Vista commented, “We are encouraged by the results received so far. Over
the last year, our geologists have been evaluating the potential continuity and connectivity of the mineralized
structures extending from the Batman deposit northeast ~5.4 Km to the Quigleys deposit. The results of this first hole
confirm our initial interpretation and suggest that additional drilling could result in the basis for an increase in the
mineral resource estimates both within and outside the currently designed Batman pit. We are now drilling the third
of three holes on a fence across the Batman North Extension. Should the results from these next three holes confirm
an extension of the structure and mineralization that forms the Batman deposit, additional drilling could ultimately
lead to future changes to the mine design.” Vista Gold CEO Video

Figure 1 – Batman Hanging Wall Lode
The plan view above shows the interpreted location of the Batman Hanging Wall Lode. VB20-001 intersected the
lode at the predicted location and encountered a thicker mineralized zone than anticipated. As shown, the Batman
Hanging Wall Lode splays off from the known Hanging Wall Lodes adjacent to the Core Zone and trends to the
northeast where it connects to a thickening zone of mineralization that is in alignment with the mineralized structure
that hosts the Golf-Tollis known mineralization.

Qualified Person
John Rozelle, Vista’s Sr. Vice President, a
Qualified Person (QP) as defined by National
Instrument 43-101 – Standards of Disclosure
for Mineral Projects , has verified the data
underlying the information contained in and has
approved this press release.
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;
4
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-m, 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.
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 either 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. NAL Pty. Ltd and Genalysis Laboratory Services Pty Ltd. are both independent of the Company.
