Drilling Intersects 14.9 g/t Gold Over 5.9 Meters and Extends Depth of Mineralization by 240 Meters at Joss

Toronto, ON – June 25^th, 2026 – Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) (“Revival Gold” or the “Company”) is pleased to report additional high-grade drill results from the Joss area at the Company’s Beartrack-Arnett Project (“Beartrack-Arnett” or the “Project”) located in Idaho, U.S.A.

Highlights

• Hole BT26-254D intercepted:
  • 2.37 g/T gold over 147.2 meters drilled width at 808 meters downhole including:
    • 9.3 g/T gold over 3.5 meters drilled width at 818 meters downhole;
    • 14.9 g/T gold over 5.9 meters drilled width at 861 meters downhole; and,
    • 9.3 g/T gold over 4.7 meters drilled width at 949 meters downhole.
  • Hole BT26-253D intercepted:
    • 4.0 g/T gold over 6.8 meters drilled width at 540 meters downhole.
  • Hole BT26-251DA intercepted:
    • 4.5 g/T gold over 4.1 meters drilled width at 719 meters downhole.
  • Complete results for previously reported BT26-252D (see Revival Gold news release dated April 20^th, 2026) include:
    • 3.1 g/T gold over 62.2 meters drilled width at 538 meters including:
      • 6.4 g/T gold over 19.1 meters drilled width at 573 meters; and,
      • 8.0 g/T gold over 4.3 meters drilled width at 596 meters.
    • This year’s drilling program targeted the expansion of the high-grade underground sulphide Mineral Resources in the Joss area, last drilled in 2022.
    • Field work on the current 2026 drilling program is expected to wrap up shortly with five primary drill holes and three wedge drill holes (total of eight pierce points) having all intersected the target Panther Creek Shear Zone (“PCSZ”) in approximately 5,500 meters of core drilling.
    • Results in BT26-254D have extended the depth of drilled mineralization in the Joss area by about 240 meters to about 850 meters below surface in the deepest hole drilled to-date on the project.
    • Joss has a known mineralized strike of about 1.2 km, and multiple higher grade (+2g/T gold) mineralized zones with horizontal (true) widths of 2-20 meters within a larger lower grade halo that ranges from 5 to 70 meters true width and remains open along strike and at depth where the PCSZ appears to be widening.
    • Results for primary drillhole BT26-255D and wedge drillholes BT26-253DW, BT26-254DW, and BT26-255DW, are pending.

“Today’s results highlight the impressive strength of sulphide mineralization at Beartrack-Arnett and extend the depth potential of the drilled underground deposit at Joss to 850 meters, increasing the deposit’s vertical dimension by 240 meters or about 70%. The deposit displays true widths of 2-20 meters in the high-grade mineralized zone and remains open at depth and beyond its existing 1.2 km of known mineralized strike”, said Hugh Agro, President & CEO. “Further results from the Joss drilling program are expected this summer and into the fall”, added Agro.

Background

The Beartrack-Arnett gold project is a structurally controlled orogenic gold deposit striking north-south within the PCSZ. The deposit is subject to an earn-in agreement for 100% by Revival Gold and is one of the Top-5 new gold discoveries made in the United States in the last fifteen years (S&P Capital IQ Pro. Discovery is defined as an increase of gold Mineral Resources and Reserves, starting from no resource in 2010 to today).

In the Joss area, the project currently hosts an underground sulphide Inferred Mineral Resource of 6,745,000 tonnes grading 4.05 grams gold per tonne for 877,000 ounces of gold that is not included in Beartrack-Arnett’s 2023 first phase open pit, heap leach PFS economics (see “Preliminary Feasibility Study NI 43-101 Technical Report on the Beartrack-Arnett Heap Leach Project, Lemhi County, Idaho, USA” prepared by Kappes, Cassidy & Associates, IMC, KCH and WSP dated August 2nd, 2023, for further details).

The current drilling program in the Joss area was designed to expand the area of known mineralization, augment an update to the Beartrack-Arnett’s mineral resources estimate, and potentially support a future underground mine economic study.

Detailed Results

Detailed results from BT26-251DA, BT26-252D, BT26-253-D, and BT26-254D are presented below.

Table 1: Detailed Drill Results

Notes:

(1) Mineralized haloes calculated including internal dilution between shears where mineralization was mostly elevated above 0.5 g/T Au and had scattered intercepts > 1 g/T Au. High grade intercepts were not capped.
(2) All included intercepts are based on a 2 g/T cutoff grade allowing up to 1.8m true width of internal dilution and requiring a minimum true thickness intercept of 7.6 g x m or minimum true thickness of 1.8 m. External dilution was excluded where the average of the external interval with dilution was below the cutoff grade.
(3) True thickness is estimated at 45-55% of drilled thickness in the reported holes.
(4) Numbers may not add due to rounding.
(5) Partial results from BT26-252D were previously reported in Revival Gold news release dated April 20^th, 2026.

QA/QC 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 Twin Falls, Idaho. Gold analyses are performed at the ALS Geochemistry laboratory in Reno, Nevada and Vancouver, British Columbia.  ALS Minerals is an ISO/IEC 17025:2017 accredited lab.

Gold assays are determined on half sawn PQ and HQ core by fire assay and Atomic Absorption Spectroscopy (AAS) on a 30-gram nominal sample weight (Au-AA23).
