REVIVAL GOLD PROVIDES UPDATE AND LATEST RESULTS FROM DRILLING AT THE MERCUR GOLD PROJECT IN UTAH

Revival Gold Inc. has provided an update on the continuing drilling program at the company's Mercur gold project in Utah.

Highlights

• Revival Gold has completed 108 holes for a total of 11,300 metres of the planned 13,000-metre drilling program.
• Received assay results from 10 additional drill holes with the following highlight intersections:
  • 1.3 g/t gold over 18.3 metres width at 33.5 metres downhole in RM25-127;
  • 0.62 g/t gold over 24.4 metres width at 56.4 metres downhole in RM25-122;
  • 0.64 g/t gold over 18.3 metres width at 48.8 metres downhole in RM25-116;
  • 0.46 g/t gold over 56.4 metres width at 53.3 metres 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 (preliminary economic assessment) 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 and chief executive officer. "Over all, 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 prefeasibility study, the next step on the path to restarting production at Mercur. We are almost 90 per cent 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, 2025).

The program at Mercur commenced on July 12 and is planned for 13,000 metres. Drilling is continuing with two RC (reverse circulation) drilling rigs focused on upgrading inferred mineral resources. As of Dec. 5, 2025, Revival Gold has completed 108 holes and 11,300 metres. Data collected will support the company's planned 2026 prefeasibility study (PFS), a major milestone on the path to restarting gold production at Mercur.

The Mercur property includes interests optioned from Barrick Resources (USA) Inc. and others as summarized in the company's preliminary economic assessment National Instrument 43-101 technical report on the Mercur gold project, Tooele & Utah Counties, Utah, U.S., prepared by Kappes, Cassidy & Associates, and RESPEC dated May 2, 2025, for further details.

QA/QC (quality assurance/quality control) program

Quality assurance/quality control consists of the regular insertion of certified reference materials, duplicate samples and blanks into the sample stream. Sample results are analyzed immediately upon receipt, and all discrepancies are investigated. Samples are submitted to the ALS Geochemistry sample preparation facility in Elko, Nev. Gold analyses are performed at the ALS Geochemistry laboratory in Reno, Nev., or Vancouver, B.C., and multielement geochemical analyses are completed at the ALS Minerals laboratory in Vancouver, B.C. ALS Minerals is an ISO/IEC-17025:2017-accredited lab.

Gold assays are determined on reverse circulation drill cuttings and quarter-sawn PQ core by fire assay and atomic absorption spectroscopy (AAS) on a 30-gram nominal sample weight (Au-AA23). One quarter of the PQ core samples were submitted for assay, one-quarter is kept for sample archive and one-half is preserved for future metallurgical column tests. For samples containing greater than 100 ppb (parts per billion) Au as determined by fire assay, gold content is also determined by cyanide leach with an AAS finish on a nominal 30-gram sample weight (Au-AA13). Multielement geochemical analyses are completed on composites samples from selected drill holes using the ME-MS 41 method.
