Revival Gold Provides Update and Latest Results From Drilling at the Mercur Gold Project in Utah TORONTO, Dec. 09, 2025 (GLOBE NEWSWIRE) -- Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) (“Revival Gold” or the “Company”) is pleased to provide an update on the ongoing drilling program at the Company’s Mercur Gold Project (“Mercur”) in Utah. Highlights Revival Gold has completed 108 holes for a total of 11,300 meters of the planned 13,000-meter drilling program. Received assay results from ten additional drill holes with the following highlight intersections: 1.3 g/t gold over 18.3 meters width at 33.5 meters downhole in RM25-127 0.62 g/t gold over 24.4 meters width at 56.4 meters downhole in RM25-122 0.64 g/t gold over 18.3 meters width at 48.8 meters downhole in RM25-116 0.46 g/t gold over 56.4 meters width at 53.3 meters downhole in RMC25-133 Three intercepts extend outside the current pit designs indicating potential upside in the Rover area of the deposit. Continued confirmation of gold occurrence, grade and leachability with PEA estimates. Drilling continues with two rigs turning and additional results are pending. “Earlier this year, Revival Gold completed a Mercur PEA defining a simple, shallow heap leach gold project. We are currently infill drilling inferred resources and have hit several intercepts outside the resource area, indicating potential upside”, said Hugh Agro, President & CEO. “Overall, we continue to see results consistent with the PEA resource and metallurgical estimates.” Mr. Agro continued, “This year’s drilling is in support of a planned 2026 pre-feasibility study, the next step on the path to restarting production at Mercur. We are almost 90% through the program and are excited by the results to date.” Details Results for RM25-126, RM25-134 and RM25-133 extend outside the current pit designs indicating potential upside in the Rover area. Leachability results for drill hole data collected to-date at Mercur are consistent with the Inferred Mineral Resource and metallurgical models developed for the Mercur Preliminary Economic Assessment (see “Preliminary Economic Assessment NI 43-101 Technical Report on the Mercur Gold Project, Tooele & Utah Counties, Utah, USA” prepared by Kappes, Cassidy & Associates, and RESPEC Company LLC dated May 2 nd , 2025). The program at Mercur commenced on July 12 th and is planned for 13,000 meters. Drilling is ongoing with two RC drilling rigs focused on upgrading Inferred Mineral Resources. As of December 5, 2025, Revival Gold has completed 108 holes and 11,300 meters. Data collected will support the Company’s planned 2026 pre-feasibility study (“PFS”), a major milestone on the path to restarting gold production at Mercur.
