Orezone’s Deep Drilling Success Raises Questions on Bomboré’s Long-Term Viability

Exploration Success at Depth

Orezone Gold Corporation has announced a fresh tranche of encouraging drill results from its flagship Bomboré Gold Mine in Burkina Faso. The latest assays confirm the presence of continuous higher-grade gold mineralization extending well below the current open pit limits, particularly in the North and P8P9 zones. Highlights include intercepts such as 1.59 grams per tonne (g/t) gold over 48 metres and 1.09 g/t over 45 metres, underscoring the potential for deeper resource growth.

These findings are part of a broader multi-year exploration program aimed at delineating the down plunge continuity of mineralized sub-zones beneath the existing life of mine pits. The results reinforce the notion that Bomboré’s mineral system remains open at depth, with broad zones of mineralization identified that do not outcrop at surface, especially in the P8P9 zone.

Strategic Implications for Resource and Production

Patrick Downey, Orezone’s President and CEO, emphasized the significance of these results in the context of the company’s long-term ambitions. The drilling success supports the potential to selectively deepen higher-grade reserve pits along the extensive 14-kilometre mineralized trend. This could materially increase Bomboré’s global resource base from the current 5 million ounces toward a targeted 7 to 10 million ounces, a goal that, while aspirational, signals strong exploration upside.

Complementing resource growth, Orezone is advancing its hard rock expansion project, aiming to boost annual gold production to between 220,000 and 250,000 ounces by late 2025. The ongoing exploration and development efforts are designed to sustain and enhance the mine’s output profile over the coming years.

Focused Drilling in Key Zones

The North Zone drilling continues to define and expand mineralized trends along a 3-kilometre strike, with mineralization hosted in structurally controlled shear zones. The North Hill sub-zone, in particular, has delivered promising grades and widths, with mineralized shoots open at depth. Similarly, the P8P9 zone has revealed wide mineralized intercepts within granodiorite units, including one of the broadest continuous mineralized zones recorded at Bomboré.

These targeted drilling campaigns complement a wider spaced step-out program aimed at discovering new higher-grade centers both near surface and at depth. Approximately 30,000 metres of drilling were completed in the first half of 2025, with plans to continue aggressive exploration in the second half of the year.

Technical Rigor and Forward Outlook

Orezone’s exploration work adheres to rigorous sampling, assay, and quality control protocols consistent with industry standards and the JORC Code. The company’s qualified personnel have verified the data integrity, lending confidence to the reported results.

While the resource expansion targets remain aspirational and subject to the usual risks inherent in mining exploration and development, the current results provide a compelling narrative of a growing, high-quality gold asset. Investors and analysts will be watching closely as Orezone advances its drilling and updates its resource models in the months ahead.
