PROMISING OUTCOME FROM COLLABORATION
WITH DUNDEE SUSTAINABLE TECHNOLOGIES
Toronto, ON – August 18th, 2025 – Revival Gold Inc. (TSXV: RVG, OTCQX: RVLGF) (“Revival Gold”
or the “Company”) is pleased to announce promising results from a program of metallurgical testing
undertaken in collaboration with Dundee Sustainable Technologies (“DST”), a subsidiary of Dundee
Corporation (TSX: DC.A), to evaluate the effectiveness of DST’s Glasslock Process™ on a high-grade
sample from the Joss deposit at the Company’s Beartrack-Arnett Gold Project (“Beartrack-Arnett”
or, the “Project”) located in Idaho, U.S.A.
Highlights
• GlassLock Process ™ testing on high-grade underground sulphide material at Beartrack -
Arnett boosted the concentrate gold grade 31% and cut the arsenic content by 99% with
almost no loss in gold.
• DST’s GlassLock Process has been successfully tested globally and used at an industrial
scale at the Tsumeb smelter facility in Namibia.
• 3,900-meter core drilling program will be kicked off later this year to continue to test and
expand on the high-grade underground potential at Beartrack-Arnett.
The DST work was undertaken subsequent to Dundee Corporation’s purchase of a strategic stake
in Revival Gold (see Revival Gold news release dated February 19 th, 2025) and followed up a
previously reported flotation testing program on a 4.6 g/T gold composite from the Joss deposit
that yielded a flotation concentrate grading 50 g/T gold, 23% sulphide sulphur and 13.5% arsenic
(see Revival Gold news release dated September 6 th, 2023). DST developed a similar arsenopyrite-
rich concentrate from Joss samples ( 50.3 g/T gold, 23.6% sulphide sulphur, 13.7% arsenic ) and
following their GlassLock Process™ the concentrate graded 66.1 g/T gold (a 31% increase), 17.9%
sulphide sulphur (a 24% reduction), and 0.19% arsenic (a 99% reduction). No measurable gold was
lost during the GlassLock Process™. The primary biproduct from the GlassLock Process™ is a stable,
insoluble, arsenic-rich glass characterized as non -toxic using Environmental Protection Agency’s
Method 1311 Toxicity Characteristic Leaching Procedure.
“DST’s Glasslock Process™ offers Revival Gold the opportunity to produce a direct- to-smelter
saleable gold concentrate from a potential second phase underground sulphide operation following
the planned open pit heap leach phase at Beartrack-Arnett”, said Hugh Agro, Revival Gold President
& CEO. “A 3,900-meter exploration drilling program will be initiated later this year as we continue
to test and expand Beartrack-Arnett’s high-grade underground potential”, added Agro.

“One of the key attractions for Dundee Corporation in getting involved with Revival Gold earlier this
year was the potential for our subsidiary business, DST, to help unlock additional value from Revival
Gold’s high-grade sulphide material ,” observed Jo nathan G oodman, President & CEO, Dundee
Corporation. “DST is expected to play a big role in the future of gold processing with Glass Lock™
already having been successfully tested on projects in Canada , the United States and Africa and
implemented on an industrial–scale to stabilize arsenic-bearing feed materials at Dundee Precious
Metal Inc.’s Tsumeb smelter facility in Namibia”, added Goodman.
Results from Revival Gold’s DST metallu rgical testing will be presented by the Company ’s, Vice
President, Engineering & Development, John Meyer, at the upcoming Nevada Mineral Processors
Division annual meeting taking place August 20-22, 2025, in Reno, Nevada.
