Vista Gold Corp. 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.
North Extension Drilling Highlights
Frederick Earnest, President and CEO of Vista, stated, “We continue to be encouraged by the results of our ongoing drilling program, which demonstrate that the Batman Core Zone extends to the north, as expected, and further validate our belief that mineralization with vertical and lateral continuity exists within and immediately adjacent to the planned Batman pit. Drilling continues on the remaining holes in our 2,400-meter program, with completion and results expected this quarter. We are presently evaluating targets for a follow-up drill program with the objective to confirm continuity and connectivity of the mineralized structures extending northeast to the Quigleys deposit.”
In the fourth quarter 2020, the Company commenced an eight-hole proof of concept 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 mineralization with vertical and lateral continuity within and immediately adjacent to the planned Batman pit.
Results from Hole VB20-001 were announced in December 2020 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. Holes VB20-002, -003, and -004 targeted the Batman North Extension to the north of the main Batman structure.
Data Verification and QA/QC
The sampling method and approach for the drillholes are as follows:
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:
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.
