Revival Gold Inc. has reported interim metallurgical column leach testing results for the Mercur Project in Utah, showing average gold extractions of 81% for oxide material and 43% for refractory material.

The ongoing metallurgical testwork is being conducted by Kappes, Cassiday & Associates at its laboratory in Reno, Nevada. The 2026 program evaluates 18 column tests across 11 metallurgical composites collected from half PQ core samples during the 2025 field season at Main and South Mercur.

Testing covers crush sizes ranging from 6.3 mm to 37.5 mm. Percolation testing on the 18 column samples required cement agglomeration at 2.0 kg per tonne prior to loading for two 6.25 mm crush samples and one 12.7 mm crush sample.

Average leach extractions to date for the nine oxide material columns stand at 81% for gold and 16% for silver over leach durations that remain ongoing. The nine refractory material columns yielded average extractions of 43% for gold and 31% for silver.

“Revival Gold's 2026 column leach testing at Mercur is progressing with interim results continuing to support the amenability of material to conventional crushed ore heap leaching” — Hugh Agro, President & CEO

The current program expands on previous metallurgical testing reported in September 2024, which evaluated five oxide composites yielding gold extractions between 74% and 92% at a 12.5 mm crush size without cement agglomeration.

Revival Gold consolidated 100% of the Mercur project in December 2025 by exercising its option to acquire Barrick Mining Corporation's interest, adding 996 hectares to bring the total project area to approximately 7,200 hectares.

Results to date remain preliminary and will be reconciled using tail assays following the completion of the program this fall.

“The data from this year's metallurgical testing program together with extensive available cyanide soluble assay data will help refine recovery and processing assumptions for the PFS targeted for completion by the end of Q1 next year” — Hugh Agro, President & CEO

Data from the program will support an upcoming Prefeasibility Study targeted for completion by the end of Q1 2027.
