Revival Gold Inc. (TSXV: RVG | OTCQX: RVLGF) has released a comprehensive project update on the Mercur Gold Project in Utah, detailing progress across resource modelling, metallurgical testing, mine design, and environmental permitting. The company is targeting completion of an updated Mineral Resource Estimate and Pre-Feasibility Study, along with the potential filing of a Notice of Intention to revise Mercur's Large Mine Operating permit, by the end of Q1 2027. The update signals meaningful technical advancement at what the company describes as Utah's largest primary gold development project. Investors may be watching the Q1 2027 deadlines as key near-term milestones.

Key Points

  • Revival Gold Inc. (TSXV: RVG | OTCQX: RVLGF) is advancing the Mercur Gold Project in Tooele and Utah Counties, Utah
  • Updated Mineral Resource Estimate, Pre-Feasibility Study, and potential Notice of Intention filing all targeted for Q1 2027
  • 24 kilometres of resource delineation drilling completed over the past 18 months; 18 metallurgical column leach tests wrapped up, with 11 more to commence shortly
  • Investors should watch for updated resource model releases, additional column leach test results, and the draft Notice of Intention submission to Utah regulators

Resource Modelling and Geometallurgical Work at Main and South Mercur

Revival Gold reports that 24 kilometres of resource delineation drilling have been completed to convert Inferred Mineral Resources to the Measured and Indicated category since the 2025 Mercur MRE and Preliminary Economic Assessment. The company's mineral resource consultant, RESPEC Company LLC, is developing updated resource models for both Main and South Mercur. Separately, consultant CS-2 Pty Ltd has completed a geometallurgical analysis leveraging historical and recent assay data, including predictive analysis, with a block-scale geometallurgical model currently in progress.

Metallurgical Column Leach Testing Highlights Agglomeration Benefits

Kappes Cassiday & Associates completed 18 column leach tests using 11 composites from 2025 drill core, with crush sizes ranging from 6.35 mm to 37.5 mm and leach cycles spanning 89 to 125 days. The release states that cement agglomerated columns yielded higher leach recoveries compared to un-agglomerated columns, while composites with elevated sulphide and carbonaceous materials showed lower recoveries than predicted. Eleven additional column leach tests are expected to commence shortly, with results anticipated in Q1 2027, targeting a better understanding of heap leach performance across varying material types.

Optimised Site Layout and Mine Design Studies Completed by WSP

Mine planning consultant WSP USA Inc. completed a trade-off study comparing heap leach facility siting options, concluding that a Main Mercur location offers more favourable geotechnical conditions and lower ore haulage costs relative to the West Mercur alternative. WSP also completed a crusher location study, establishing a preferred position near the south-western limit of the Rover Pit. Additionally, a bench height trade-off study found that reducing bench height to 6.1 metres and using smaller trucks and loading units is economically more attractive than the 7.6-metre configuration used in the PEA.

Environmental Baseline Studies and NOI Submission on Track for Q1 2027

Environmental baseline field work conducted under permitting consultant Stantec Consulting Services Inc. is described as largely complete across air quality, aquatic resources, cultural heritage, hydrogeology, soils, and wildlife categories. Stantec has begun incorporating baseline data into a draft Notice of Intention for submission to the Utah Division of Oil Gas & Mining, expected in Q1 2027. The release states that approval for a revision to the existing Large Mine Operating permit is expected within approximately twelve months of NOI filing through the state-led permitting process.
