Vista Gold Corp. reports drilling and test results for historic heap leach pad at Mt. Todd

Denver, Colorado, May 16, 2012 - Vista Gold Corp. (TSX & NYSE MKT: VGZ) (“Vista” or the “Company”) is pleased to announce the initial results of a sampling and metallurgical testing program on the existing heap leach pad at its Mt. Todd gold project in Northern Territory, Australia.

To date, the existing heap leach pad has been considered an environmental liability; however, as part of the ongoing feasibility study, Vista completed a review of the historic blast hole and production data associated with the heap leach pad and concluded that there may be potential to recover additional gold from the existing heap leach pad.

Fred Earnest, Vista’s President & CEO, stated “the drilling and subsequent bottle roll test results from the existing Mt. Todd heap leach pad are causing us to consider some new aspects of the Mt. Todd gold project.

The potential to convert what we had previously considered to be a brownfield site liability to a potential revenue generating component of the project could represent a potentially significant source of additional value.

We are in the process of evaluating the potentially favorable implications and timing of gold production from the existing heap leach pad and believe that the heap leach pad should be incorporated into the definitive Mt. Todd feasibility study. We are currently evaluating the impact this may have on our current feasibility study.”
