VANCOUVER, British Columbia -- 

Viva Gold Corp. (TSX-Venture: VAU; OTCBB: VAUCF) (the “Company” or “Viva”) is pleased to announce that it will initiate a Preliminary Economic Assessment (“PEA”) of its Tonopah gold project based on receipt of positive preliminary metallurgical column testwork and results from its fall 2019 drilling program. The Tonopah project is located on the prolific Walker Lane mineral trend in western Nevada, near the town of Tonopah.

“Viva is pleased to advise that it intends to retain Gustavson Associates of Lakewood, Colorado to initiate a PEA of the Tonopah gold project. A strong gold price outlook, positive metallurgical test results, and completion of the recent exploration step-out drilling program is driving this decision. The Tonopah project includes a robust core of pit-constrained measured and indicated, plus inferred gold resource, sufficient in size to contemplate an open-pit heap leach recovery operation to produce up to 50,000 ounces of gold per year, which we believe will be supplemented with additional self-funded discovery of additional gold resources over time. The PEA will help Viva to put a solid valuation under its share price and will open potential strategic options for the Tonopah project,” states James Hesketh, President and CEO.

Mineral Resource

As announced on July 16, 2019, Viva has filed a NI43-101 Technical Report on Mineral Resources at Tonopah supporting a pit-constrained measured and indicated gold resource estimate containing 253,000 ounces, plus an additional 123,000 ounces of inferred resource. This estimate was completed utilizing a gold price of $1,250 per ounce and an average gold recovery of 70%. The resource estimate is sensitive to price and recovery and is likely to increase in size with either higher gold price or gold recovery rates.

Metallurgical Testwork

In August 2019, Viva retained McClelland Laboratories Inc. of Sparks, Nevada to initiate 60-day column leach tests on four composite samples derived from drillholes TG1805-TG1815. These holes were drilled as confirmation holes in and around the measured and indicated resource area. Assay reject samples from this program were composited by rock type, sized to a nominal 80% passing 10 mesh size, and agglomerated with cement for testing. These are the first column tests performed on Tonopah project drill samples.

Column leach test results for samples taken from the Palmetto argillite formation, which contains approximately half of the total gold resource at Tonopah, leached quickly and resulted in gold recovery of over 90%, which, if further verified, will provide a significant economic driver to the project. Recovery rates in the overlaying Tertiary volcanics, a complex assemblage of locally silicified rhyolite tuffs, greywacke, air-fall tuffs and siltstone, show slower recovery rates, but with additional time under leach are expected to approximate the 70% recovery range. Incremental gold recovery was still occurring in all of the columns when the tests were terminated. It is anticipated that an additional 2% to 5% recovery may be possible with additional time under leach. Final results are expected within about a month. Preliminary leach results are shown in the following table:

Drillhole Results

Viva completed a total of 10 reverse circulation (RC) drill holes totaling approximately 1,520 meters. Drillhole locations for this step-out exploration program were designed to test undrilled areas along the northwest trending flank of Palmetto Argillite formation at the Tertiary volcanic contact over a distance of about two kilometers around and between the Midway Hills and the Mineral Resource area. Geophysical survey data combined with historic drilling was utilized to predict the locations of structural junctions and splays for drillhole targeting. The Midway Hills area was last drilled in the 1990’s. Significant intercepts within those holes are shown in the attached table.

“All of the drillholes in this program penetrated the Palmetto argillite/Tertiary volcanic contact zone and encountered hydrothermal alteration, silicification, quartz veining and sub-grade gold mineralization. This program was geologically encouraging in that it confirmed the presence of gold bearing mineralization over a large area, demonstrating the significant size potential of the project. The cross cutting structural features that are often associated with high-grade mineralization at the Tonopah project were not encountered in this program. Additional analysis is required to determine the magnitude and direction of structural movements to improve drill targeting in future drill programs,” states Ed Bryant, project geologist.

The Tonopah property contains a near-surface low-sulfidation epithermal gold system which includes near vertical quartz-adularia-gold veins hosted by Ordovician age Palmetto argillite and the overlying Tertiary rhyolitic volcanics all within a low-angle zone of gold mineralization which includes and often parallels an erosion surface discontinuity at the top of the Palmetto argillite. Mineralization has been identified in a series of north-striking extensional structural zones within an overall mineralized trend along the north-northwest Walker Lane trend.
