REVIVAL GOLD PROGRESSES DRILLING

AND DEVELOPMENT ACTIVITIES AT MERCUR

Toronto, ON – September 8th, 2025 – Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) (“Revival Gold”

or the “Company”) is pleased to provide an update on drilling and development activities at the

Company’s Mercur Gold Project (“Mercur” or, the “Project”) located in Utah, U.S.A.

Drilling Highlights

• Two rigs operating at Mercur since July have completed approximately 3,200 meters of a

planned 13,000-meter drilling program at Mercur this year.

• Six PQ core holes have been drilled to collect material from the east walls of the Main

Mercur pits and Rover area for column leach testing. Twenty-two RC holes have been drilled

in the Marion Hill and Rover areas to infill historical drilling (Figure 1).

• Core and chip logging is ongoing with Revival Gold having implemented Datarock Pty Ltd’s

geoscience platform this season to process chip tray images and utilize machine learning to

help interpret the data. Optical televiewer images have been collected from two core holes

to support geotechnical studies on the project.

• 1,300 samples have been submitted to ALS Assay Lab from sixteen holes.

• RC drilling has predominantly been targeted to infill Inferred Mineral Resources in the

Rover area, with some holes planned to pursue potential extensions outside the existing

mineral resources.

• Core drilling will continue to focus on collecting representative metallurgical samples

throughout the Main Mercur area. Planned core drilling at South Mercur this year remains

subject to permitting approval by Utah’s Division of Oil, Gas and Mining.

Development Highlights

• Revival Gold has engaged Stantec Consulting Services Inc. and KTW Environmental

Consultants LLC to evaluate the existing environmental baseline information , identify

supplemental baseline data requirements and develop baseline work plans.

• Kappes, Cassiday & Associates has been engaged to oversee metallurgical sample

collection, design metallurgical composites in support of future metallurgical testing, and

2

coordinate with our permitting team to develop a project description and footprint to

optimize project permitting timelines and project economics.

• Subterra LLC has been engaged to support drilling-related geotechnical data collection and

to develop Pre-Feasibility Study (“PFS”)-level open-pit geotechnical models.

• RESPEC Company LLC has been retained to refine and update 3D models for mineral

resource estimating purposes in support of a PFS.

“With two rigs operating and a third on its way, we’ve completed about a quarter of the planned

13,000-meter drilling program at Mercur this year”, said Hugh Agro, President & CEO. “Meanwhile,

key components of the Mercur development consulting team have coalesced under the leadership

of our VP, Engineering & Development, John Meyer, in preparation for the potential completion of

a PFS and the formal launch of mine permitting in 2026. Initial assay results from the drilling

program are expected later this fall”, added Agro.
