Viva Gold Announces Additional Results from Tonopah Gold Project Drill Program

VANCOUVER, BC — May 13, 2026 — Leads & Copy — Viva Gold Corp. has announced additional results from its 2026 reverse-circulation (RC) drill program at the Tonopah Gold Project in western Nevada.

The company said the drill program, designed to expand and infill gold mineralization, aims to upgrade inferred resources to a level supporting conversion to mineral reserves in the pre-feasibility study. Nineteen holes totaling 3,210 meters have been drilled, including three exploration holes at the Midway Hills prospect.

Assay results have been received for eight holes (TG2601–TG2608), with results for TG2601–TG2604 and preliminary data for TG2608 disclosed on April 23, 2026. Assays for the remaining 11 holes are pending.

James Hesketh, President & CEO, stated that the new mineral intercepts are within the 2025 PEA resource shell in areas previously categorized as either waste or inferred mineralization. He added that the results are potentially adding to shallow high-grade mineralization that can be mined early in the mine life and are likely to convert inferred mineralization to measured and indicated status while also adding new zones of inferred mineralization. Hesketh believes these upgrades in both category and grade should help reduce strip ratio and add to the economics of the ongoing pre-feasibility study for Tonopah.

Key highlights from the latest assay returns include:

• TG2606: 51.8 meters @ 2.34 grams per tonne (g/t Au), including 32 m at 3.14 g/t, which included 9.1 m @ 9.3 g/t, containing 1.5 m @ 26.3 g/t, all in five zones between 21.3- and 163.1-meters depth;
• TG2608: 65.5 m @ 0.48 g/t Au in four zones between 25.9- and 137.2-meters depth;
• TG2607: 16.8 m @ 0.37 g/t in three zones between 56.4- and 115.8-meters depth.
• TG2605: 19.8 m @ 0.36 g/t in two zones between 62.5- and 123.4-meters depth

The Tonopah Gold Project is located on the Walker Lane Mineral Trend in western Nevada, approximately 30 minutes south of Kinross Gold’s Round Mountain Mine. Viva Gold has defined a high-confidence gold mineral resource and demonstrated the potential for an economically viable open-pit, heap leach/mill gold project through its 2025 preliminary economic assessment (PEA).

Viva Gold utilizes a documented system of inserting blanks and standards into the assay stream and maintains a strict chain of custody for samples. Assays are completed at independent laboratories with internal quality assurance and quality control systems and procedures. American Assay Laboratories Inc. of Reno, Nevada, performed the assays using fire assay and ICP methods with gravimetric finish.

James Hesketh, MMSA-QP, approved the scientific and technical disclosure in this release.

Viva Gold trades on the TSX Venture Exchange (“VAU”), the OTCQB (“VAUCF”), and the Frankfurt Exchange (“7PB”). Viva currently has approximately 172 million shares outstanding.
