One Bullion Secures Fully Funded August Drill Campaign Following

Completion of Vumba Geophysics

Vumba Geophysical Survey Completed and Maitengwe Survey Approximately 40% Complete

as the Company Moves from Target Generation to Drilling

Maiden Diamond Drill Program of ~3,000 Meters to Begin in August 2026 with Mindea

Exploration and Drilling Services (Pty) Ltd.

Toronto, Ontario – July 15, 2026 – One Bullion Ltd. (“One Bullion” or the “Company”) (TSXV:

OBUL), a gold exploration company holding complete ownership of three highly prospective

exploration projects in Botswana, today announced 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, continued advancement of exploration at Maitengwe, and the full funding 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% 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 meters of HQ diamond drilling scheduled to

commence in August 2026

• Entire ~3,000-meter drill program fully funded

• Newly acquired geophysical data being integrated with the Company’s extensive historical

geological, geochemical and structural datasets to refine and prioritize drill targets

Geophysical Surveys at Vumba and Maitengwe

The Company has successfully 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 either not evident at surface, or where surface

expression is too obscured by cover to identify trends. This enables more accurate drill targeting

and improving the probability of exploration success.

At the Maitengwe Gold Project, geophysical surveying is progressing well, with approximately

40% of the program now 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 is received, One Bullion’s technical team , including interpretation and

insights from Campbell & Walker Geophysics, has begun processing and interpret ing the

magnetic data for integration into the Company’s extensive historical geological datasets. 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 (Pty) Ltd. 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 meters 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 meter drill program is fully funded, 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.
