ONE BULLION SECURES FULLY FUNDED AUGUST DRILL CAMPAIGN FOLLOWING COMPLETION OF VUMBA GEOPHYSICS

One Bullion Ltd. has provided an exploration update highlighting progress across its Botswana gold exploration portfolio.

The company has achieved several key milestones, including the completion of geophysical surveying at Vumba, the continued advancement of exploration at Maitengwe and the full financing of its inaugural drill campaign, which is scheduled to commence August, 2026.

"The completion of geophysics at Vumba, strong progress at Maitengwe and the execution of our drilling contract mark key milestones as we transition from target generation into drilling," said Adam Berk, chief executive officer of One Bullion. "Our technical team is integrating the newly acquired geophysical data with several years of exploration results to refine and prioritize the highest-quality drill targets. With funding secured and drilling scheduled to begin in August, 2026, we are excited to commence this important phase and test the exploration potential of our Botswana portfolio."

Highlights:

• Completed the high-resolution geophysical survey at the Vumba gold project, an important milestone in advancing one of Botswana's underexplored greenstone belts;
• Geophysical survey at the Maitengwe gold project approximately 40 per cent complete and progressing as planned;
• Executed a diamond drilling contract with Mindea Exploration and Drilling Services Pty. Ltd. for the initial phase of drilling in Botswana, with mobilization expected by August, 2026;
• Maiden program of approximately 3,000 metres of HQ diamond drilling scheduled to commence in August, 2026;
• Entire approximately 3,000-metre drill program fully financed;
• Newly acquired geophysical data being integrated with the company's extensive historical geological, geochemical and structural data sets to refine and prioritize drill targets.

Geophysical surveys at Vumba and Maitengwe

The company has completed its high-resolution geophysical survey at the Vumba gold project, marking an important milestone in advancing one of Botswana's underexplored greenstone belts. Geophysical surveys of this nature help to map stratigraphy and structures, delineating potential mineralized targets that are not evident either at surface or where surface expression is too obscured by cover to identify trends. This enables more accurate drill targeting and improves the probability of exploration success.

At the Maitengwe gold project, geophysical surveying is progressing well, with approximately 40 per cent of the program completed. Data acquisition continues as planned, and the company expects the survey to provide valuable information to refine and prioritize drill targets across the project.

As geophysical data are received, One Bullion's technical team, including interpretation and insights from Campbell & Walker Geophysics, has begun processing and interpreting the magnetic data for integration into the company's extensive historical geological data sets. This work is expected to further enhance target definition ahead of future drilling campaigns across both project areas.

Maiden drill program

In preparation for drilling, the company has executed a drilling contract with Mindea Exploration and Drilling Services to conduct the initial phase of diamond drilling in Botswana. Under the agreement, mobilization is expected to begin by August, 2026, with drilling commencing shortly thereafter.

The inaugural program will consist of approximately 3,000 metres of HQ diamond drilling, scheduled to commence in August, 2026. HQ-diameter core has been selected to maximize core recovery, geological logging quality and structural interpretation, providing the technical team with high-quality samples for geological, geotechnical and future metallurgical evaluation.

Importantly, the entire 3,000-metre drill program is fully financed, allowing the company to execute the campaign without requiring additional financing.

Next steps

The company's exploration strategy continues to focus on systematically advancing its highly prospective land package through modern exploration techniques, disciplined target generation and phased drilling programs designed to maximize discovery potential.

Further updates will be provided as the company's exploration program advances.
