On October 5, 2020, Vista Gold Corp. filed a technical report titled “NI 43-101 Technical Report Mt Todd Gold Project 50,000 tpd Preliminary Feasibility Study Northern Territory, Australia,” dated October 7, 2019, with an effective date of September 10, 2019 as amended September 22, 2020, (the “Technical Report”), with the securities regulatory authorities in Canada.
The Technical Report provides updated material, scientific, and technical information based on additional data obtained from extensive metallurgic test work conducted in 2018 and 2019. The recent metallurgic test programs have confirmed: (1) the efficiency of ore sorting across a broad range of head grades and the natural concentration of gold in the screen undersize material prior to sorting; (2) the efficiency of fine grinding and improved gold leach recoveries at an 80% passing grind size of 40 microns; and (3) the selection of FLSmidth’s (FLS) VXP mill as the preferred fine grinding mill.
In September, 2020, the Technical Report was amended to correct and/or clarify certain items, including:
| · | Changes to the title page to include each Qualified Person’s (QP) professional designation to comply with form requirements |
| · | Clarification of QP disclaimers and additions to Section 3 – Reliance on Other Experts to comply with form requirements |
| · | Additions to Section 9 - Exploration and Section 10 - Drilling to comply with form requirements |
| · | Clarification of credentials in certificates for specific QPs |
| · | Adjustment of measured, indicated, and inferred mineral resources for Quigleys deposit |
| · | Certain other minor changes to comply with form requirements |
There are no changes to the following key items in the Technical Report:
| · | Reported measured, indicated, and inferred mineral resources for Batman deposit |
| · | Reported design parameters for the open pit mine plans |
| · | Reported proven and probable mineral reserves |
| · | Reported design parameters for the process plant or process flow sheet |
| · | Reported metallurgical recoveries and associated supporting test work |
| · | Reported capital and operating costs |
| · | Reported design parameters for the tailings dams and waste rock dump |
| · | Reported design parameters and associated costs for the reclamation plan |
| · | Reported financial results from the cash flow analysis, rates of return, and schedules |
This information is intended to assist stakeholders and other readers of this Technical Report in their understanding of the Mt Todd Gold Project and in forming judgements regarding the quality of the data collected, reported, and used in the Technical Report. The highlights of the PFS are presented in the following table:
