Opus One Gold Completes 2026 Drill Program at Noyell, Extending Zone 1 Gold Mineralization From Surface to Approximately 750 Metres and Remaining Open at Depth

MONTREAL, Sept. 16, 2026 (GLOBE NEWSWIRE) — Opus One Gold Corp. (TSX-V: OOR) (the “Company” or “Opus One”) is pleased to announce the final assay results from its 2026 drilling program on its 100%-owned Noyell Gold Property, located in the northern portion of the Abitibi Greenstone Belt near Matagami, Quebec.

Those final results are completing a successful 2026 drilling campaign that significantly advanced the Company’s understanding of the Noyell property gold system. Released drill holes true width values were calculated using Geotic Log software.

Most importantly, drilling has now traced the Zone 1 gold-mineralized structure continuously from surface down to approximately 750 metres vertical depth, where it remains open at depth.

The 2026 program also identified a strong mineralized vector in the eastern portion of Zone 1, highlighted by previously announced hole NO-26-21a, which returned 4.92 g/t Au over 11.37 metres (9.08 metres true width) at approximately 700 metres vertical depth (June 17h, 2026 press release)

In addition, Opus One’s first drilling program, approximately 3 kilometres west of Zone 1 at the West boundary of Noyell property, successfully intersected gold mineralization in all five holes drilled across approximately 800 metres of strike at the newly explored Zone West, providing the Company with a second priority area for follow-up drilling.
