Opus One Gold Corp (TSX-V: OOR) (the "Company" or "Opus One") is pleased to announce that two drill rigs have been mobilized on its 100% owned Noyell gold project located in the Abitibi mining district close to the mining town of Matagami in Quebec province, Canada. A third rig could be added in February if it is deemed necessary to complete the program. The drill program follows-up on Opus One's 2025 very successful program on its Zone 1 gold discovery.

The diamond drilling program will consist of approximately 26 holes adding up to around 14,000m of core. Numerous drilling targets have been identified to infill and to extend Zone 1 in all directions (see longitudinal section and maps). Additionally, Opus Ones will test a new area in the western portion of the property where significant gold was reported in drill records in the 80's and 90's by previous operators.

This new target area is located approximately 3km to the west of Zone 1 and corresponds to the eastern extension of significant gold mineralization being currently defined by drilling on the neighboring property to the west (N2 Project, Formation Metals, formerly Wallbridge). The N2 project already hosts a significant historical gold resource (Press release, Dec. 11th, 2025) and a major drilling program is in progress.

Opus One's interpretation indicates that the gold mineralization observed in its western portion of the property appears to correspond to the same geological gold bearing structure which hosts Zone 1 in the central portion of the property. A total of 5 shallow holes will be drilled on this target. These will be the first holes performed by Opus One in this portion of the property.

Louis Morin, Opus One CEO, commented: We are very enthusiastic about our upcoming new drill program. In 2025, Opus One completed 9,000 m of successful drilling on its Zone 1 discovery, carried out a bio-geochemical sampling survey around Zone 1 and a laser induced breakdown spectrometry study on mineralized core to characterize the gold bearing horizon and host units. Additionally, Opus One is developing new quality gold targets on the property. The company is therefore expanding its main mineralized zone, initiating the mineralogical characterization of its gold bearing structure and gearing up for new discoveries along the same favorable structure and, hopefully, along parallel ones. No doubt 2026 will be another exciting year for the company.
