ONE BULLION LIMITED ANNOUNCES HIGH RESOLUTION AIRBORNE GEOPHYSICAL SURVEY TO ADVANCE DRILL TARGETING AT VUMBA AND MAITENGWE PROJECTS

One Bullion Ltd. has engaged Xcalibur Smart Mapping to conduct a comprehensive high-resolution airborne magnetic gradiometer and radiometrics survey over both the Vumba and Maitengwe projects in the northeast and central districts of Botswana, respectively. The planned surveys represent a key milestone as the company advances toward drill-ready targets in its 2026 exploration program.

"These surveys are a critical step in systematically unlocking value across our portfolio and positioning the company for a focused and efficient drill program later this year," said One Bullion's chief executive officer, Adam Berk. "Following our successful public listing late last year, we are moving aggressively to advance our assets. High-resolution geophysical data will significantly improve our ability to prioritize targets, allocate capital effectively and accelerate exploration momentum as we enter 2026."

The airborne geophysical program will comprise approximately 16,350 line kilometres of survey coverage, including 2,400 line km over the Vumba project and 13,950 line km over the Maitengwe project, inclusive of tie lines. Surveys will be flown at a 50-meter line spacing with 500-meter tie lines, and will be conducted by Xcalibur, utilizing a horizontal magnetic gradiometer system, complemented by radiometric and sensors. This configuration will deliver high-sensitivity magnetic data and fully corrected, levelled data sets suitable for advanced geological interpretation.

The resulting magnetic, radiometric and gravity products are expected to materially enhance the company's understanding of the subsurface stratigraphy under the project areas. This is particularly significant at Maitengwe, which is a large land package, covering 580.75 square kilometres, where geological exposure is minimal due to a veneer of young Kalahari sediments. The surveys are designed to help identify prospective structural corridors and geological features that may host mineralization, thereby reducing exploration risk ahead of planned drilling.

The surveys are expected to commence within the next few weeks and will require approximately five weeks to complete across both project areas. Preliminary geophysical results are anticipated within one week of survey completion, followed by fully processed and interpreted data sets approximately four weeks later, supporting the company's 2026 exploration and drill planning efforts.
