One Bullion Launches High-Tech Survey to Uncover Botswana's Gold

VANCOUVER, BC – January 27, 2026 – In a decisive move to accelerate its exploration efforts, newly-listed gold explorer One Bullion Ltd. (TSXV: OBUL) has commissioned a massive high-resolution airborne geophysical survey over its key projects in Botswana. The company has engaged Xcalibur Smart Mapping, a global leader in geophysical services, to fly over 16,000 line-kilometers, deploying advanced magnetic and radiometric sensors to peer beneath the earth's surface and define drill-ready targets for its 2026 exploration program.

The survey will cover the Vumba and Maitengwe project areas, both located in highly prospective greenstone belts known for gold mineralization. This initiative marks a critical step for the Toronto-based company as it transitions from a privately funded explorer to a publicly-traded entity focused on unlocking the potential of its extensive land holdings in one of Africa's most stable mining jurisdictions.

An Aggressive Post-Listing Play

Having successfully listed on the TSX Venture Exchange late last year, One Bullion is wasting no time in putting its capital to work. The commissioning of this extensive and technologically advanced survey signals an aggressive strategy to build on years of foundational exploration and rapidly advance its assets toward discovery.

“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, in a statement. “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.”

This operational push is supported by recent corporate actions designed to strengthen its market presence and governance. The company recently entered into a market-making agreement with Independent Trading Group (ITG) to improve trading liquidity for its shares. It also announced a significant grant of restricted share units to key leadership, aligning management's long-term interests with shareholder value creation. Together, these moves paint a picture of a company methodically building the corporate and operational framework needed to support an ambitious exploration campaign.

Piercing the Veil of the Kalahari

The technological aspect of the survey is central to its significance, particularly at the expansive Maitengwe project. Covering over 580 square kilometers, the project lies under a veneer of young Kalahari sediments—a thick blanket of sand and gravel that effectively conceals the bedrock geology below. This makes traditional surface-based prospecting methods like mapping and sampling largely ineffective.

This is where Xcalibur Smart Mapping's expertise comes in. The Perth-based firm will utilize a horizontal magnetic gradiometer system with high-sensitivity Cesium Vapour sensors, capable of detecting minute variations in the Earth's magnetic field. These variations help geologists map different rock types, identify faults, and pinpoint structural corridors that often act as conduits for gold-bearing fluids. The survey will be flown at a tight 50-meter line spacing to generate an incredibly detailed picture of the subsurface architecture.

Combined with radiometric sensors that measure natural radioactive elements in the rocks below, the resulting datasets will allow One Bullion's technical team to 'see through' the Kalahari cover. This dramatically de-risks the exploration process by allowing the company to focus its future drilling on precise, data-driven targets rather than drilling blindly into the sand. Xcalibur's technology has a proven track record in similar covered terrains across Southern Africa, having been instrumental in discoveries by providing the critical subsurface information needed for informed decision-making.

Botswana: A Golden Opportunity Beyond Diamonds

One Bullion's significant investment underscores the growing interest in Botswana's potential as a major gold producer. While the country is world-renowned for its diamond industry and political stability, its vast greenstone belts—geological formations that host many of the world's largest gold deposits—remain comparatively underexplored.

The company's Vumba and Maitengwe projects are situated within the Francistown area, a region that is part of a major gold-producing geological trend extending into neighboring Zimbabwe. This area already hosts established gold operations, such as the Mupane and Monarch mines, proving the region's prospectivity. By securing a commanding land package of over 8,000 square kilometers across three projects, One Bullion has positioned itself as a key player in the potential diversification of Botswana's mining sector.

The country's pro-mining policies, transparent regulatory framework, and well-developed infrastructure provide a secure and supportive environment for long-term investment, making it one of the most attractive mining jurisdictions on the continent. One Bullion's systematic, data-driven approach aligns with the country's desire to see its other mineral resources developed responsibly.

From Data to Drill-Ready Targets

The upcoming survey is not being conducted in a vacuum. At the Vumba project, it will build upon an extensive history of previous work, including historical surface sampling that returned high-grade gold values up to 116 g/t Au, as well as significant trenching and drilling. An earlier Induced Polarization (IP) survey at Vumba already identified 26 high-priority targets. The new, high-resolution magnetic and radiometric data will add another crucial layer to this geological model, refining targets and potentially identifying new ones along the known gold-hosting structures.

For the largely unexplored Maitengwe project, the survey is a true game-changer, providing the first-ever comprehensive look at the geology hidden beneath the sand. The 13,950 line-kilometers planned for Maitengwe dwarf the 2,400 line-kilometers at Vumba, reflecting its scale and the critical need for this foundational data.

The survey is expected to commence within weeks and take approximately five weeks to complete. According to the company, preliminary results will be available within a week of completion, with fully processed and interpreted datasets arriving about a month later. This data will be the foundation upon which One Bullion builds its 2026 drill program, shaping the company's exploration activities for the remainder of the year and beyond.
