Engagement of Xcalibur Smart Mapping to Accelerate Exploration Momentum Following Successful Public Listing

VANCOUVER, British Columbia, Jan. 27, 2026 (GLOBE NEWSWIRE) -- One Bullion Ltd. (“One Bullion” or the “Company”) (TSXV: OBUL), a gold exploration company holding complete ownership of three highly prospective mining areas in Botswana, is pleased to announce that it has engaged Xcalibur Smart Mapping to conduct a comprehensive high resolution Airborne Magnetic Gradiometer and Radiometrics survey over both Vumba and Maitengwe projects, in the North-East 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 CEO, 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-kilometers of survey coverage, including 2,400 line-km over the Vumba project and 13,950 line-km over 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 (0.01 nT) and fully corrected, levelled datasets 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 km², 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 datasets approximately four weeks later, supporting the Company’s 2026 exploration and drill planning efforts.
