One Bullion Commences High-Resolution Airborne Geophysical Survey at Vumba Gold Project in Botswana and Appoints Joe Van Wyk as Vice President, Exploration

One Bullion Limited announced the commencement of a high-resolution airborne geophysical survey at its Vumba Gold Project in Botswana, which is being conducted by Xcalibur Smart Mapping. The company also appointed Joe Van Wyk as Vice President, Exploration, to provide on-the-ground oversight of field operations and geological team management.

The maiden drill campaign at Vumba is fully funded, targeting approximately 3,000 meters across ~15 holes. The program is expected to commence in August 2026 following survey interpretation, with initial survey results and interpretation anticipated by late July 2026.

One Bullion Limited (OBUL) has taken a routine step in its exploration cycle, following up on high-grade artisanal sampling results from April and May 2026 and a survey engagement announcement made in January 2026. The company has appointed a VP of Exploration and confirmed a fully funded maiden drill program, milestones that advance the timeline for data acquisition ahead of drilling.

The announcement does not introduce new capital, change the company's financial trajectory, or alter its fundamental risk profile.

One Bullion Limited controls approximately 8,004 km² of prospective land across three greenstone belt-hosted gold projects in Botswana: Vumba, Kraaipan, and Maitengwe. The flagship Vumba Gold Project has seen high-grade artisanal sampling results, including 679 g/t Au and 30.8 g/t Au, confirming a mineralized corridor. Historic drilling at Vumba returned high-grade intercepts, such as 41.50–44.00 m (2.50 m at 42.82 g/t Au). The company is in the exploration stage with no defined mineral resources or reserves.
