Revival Gold Extends High-Grade Mineralization to Greater Depths at Joss

• Hole BT26-254D returned 14.9 grams per tonne (g/t) gold over 5.9 metres, within a broader interval of 2.37 g/t gold over 147.2 metres.
• Drilling extended the depth of known mineralization at Joss by about 240 metres to approximately 850 metres below surface, the deepest point tested on the project to date.
• Additional intercepts from holes BT26-253D and BT26-251DA returned 4.0 g/t gold over 6.8 metres and 4.5 g/t gold over 4.1 metres, respectively.
• The 2026 drill program has completed approximately 5,500 metres of core drilling across eight pierce points, all of which intersected the target structure.
• Results from four additional drill holes remain pending and are expected in the coming months.

Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) is a Canada-based gold mine developer with a portfolio of development and exploration projects in the United States. The company is advancing its Mercur Gold Project in Utah while continuing exploration at its Beartrack-Arnett Gold Project in Idaho. Headquartered in Toronto, Canada, Revival Gold also maintains a U.S. exploration and development office in Salmon, Idaho.

High-Grade Drill Results Including 14.9 g/t Gold Over 5.9m at Joss Underground Target

The latest results from the Joss area confirm high-grade gold mineralization within the Panther Creek Shear Zone, the geological structure hosting the deposit. Hole BT26-254D intersected a broad zone of mineralization measuring 147.2 metres, grading 2.37 g/t gold, which included a higher-grade section of 14.9 g/t gold over 5.9 metres. The same hole also returned intervals of 9.3 g/t gold over 3.5 metres and 9.3 g/t gold over 4.7 metres.

Hole BT26-253D intercepted 4.0 g/t gold over 6.8 metres at 540 metres downhole, while hole BT26-251DA returned 4.5 g/t gold over 4.1 metres at 719 metres downhole. Complete results from previously reported hole BT26-252D, first disclosed on April 20, 2026, included 3.1 g/t gold over 62.2 metres, with higher-grade sections of 6.4 g/t gold over 19.1 metres and 8.0 g/t gold over 4.3 metres.

President and CEO Hugh Agro said:

"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."

Depth Extension of Mineralization by 240 Metres to 850m Below Surface

Results from hole BT26-254D extended the depth of drilled mineralization in the Joss area by approximately 240 metres, to about 850 metres below surface, marking the deepest hole drilled on the project to date. This represents an increase of about 70% in the deposit's known vertical dimension.

Joss has a known mineralized strike length of about 1.2 kilometres. Higher-grade zones, defined as greater than 2 g/t gold, measure 2 to 20 metres in true width and sit within a broader, lower-grade zone ranging from 5 to 70 metres in true width. Both the strike length and depth of the deposit remain open, with the Panther Creek Shear Zone appearing to widen at depth.

The Joss area currently hosts an underground inferred mineral resource of 6,745,000 tonnes grading 4.05 grams gold per tonne, containing 877,000 ounces of gold. This resource is separate from the open pit, heap leach project outlined in Beartrack-Arnett's 2023 preliminary feasibility study.

2026 Drill Program Supporting Future Resource Update and Underground Economic Study

The current drilling campaign at Joss, the first at the target since 2022, was designed to expand the area of known mineralization. Field work is nearing completion, with five primary drill holes and three wedge holes, totalling eight pierce points, all having intersected the target structure across approximately 5,500 metres of core drilling.

Results from primary hole BT26-255D and wedge holes BT26-253DW, BT26-254DW, and BT26-255DW remain pending. The program is intended to support an updated mineral resource estimate for Beartrack-Arnett and to inform a potential underground mine economic study.

Agro added:

"Further results from the Joss drilling program are expected this summer and into the fall."

Outlook and Next Steps

Revival Gold expects to report the remaining pending drill results later this summer and into the fall. These results, together with today's findings, are intended to support an updated mineral resource estimate and a future underground economic study for the Joss target.
