One Bullion Commences 2026 Diamond Drilling Program at Vumba Gold Project
One Bullion Limited (OBUL) has commenced its 2026 diamond drilling program at the Vumba Gold Project in Botswana, marking the start of a planned 3,000-meter HQ program across ten holes. The drilling strategy is based on a completed integrated technical review that identified three priority mineralized structural corridors—Central, South, and North—where geological, geochemical, and geophysical datasets converge. The program aims to define the orientation, continuity, and plunge of mineralized structures and higher-grade shoots using oriented HQ core to build a robust 3D geological model.
The drilling objective is to test the orientation, continuity, and plunge of known mineralized structures and higher-grade shoots, while investigating continuity at depth, the true geometry of zones, controls on higher-grade shoots, structural bends, splays, and intersections, quartz-vein and sulfide distribution, and alteration patterns. The Central Corridor is the highest-priority target, containing known gold mineralization, historical drilling, high-grade surface occurrences, and structurally complex geology. The first hole, VUDD017, is testing this area. The South Corridor consists of a compact cluster of historical drilling, trenching, and surface results associated with a steep structural and lithological corridor, with testing focused on continuity and geometry. The North Corridor features established gold mineralization with a strong association to arsenic, sulfidation, and mafic host rocks, with the program testing deeper continuity and structural linkage.
In addition to the Vumba project, One Bullion completed a high-resolution airborne magnetic survey at its Maitengwe Project, which is currently being processed and interpreted to refine targets for future exploration.
Regarding administrative updates, the company issued 875,000 earned restricted share units (RSUs) to officers and directors. One Bullion also extended its consulting agreement with SLD Capital Corp. for an additional six-month term. Under the terms of this agreement, SLD Capital Corp. is entitled to receive approximately 83,333 common shares per month during the term, subject to TSX Venture Exchange acceptance.
Adam Berk, CEO, commented on the development: “This is an important step forward for One Bullion and the Vumba Gold Project... We are now testing the areas where multiple independent datasets point to the strongest potential for continuity and scale.” He added, “The focus of this program is to move Vumba from identifying gold mineralization to defining the geometry, continuity and structural controls of the system... position the Company for the next phase of systematic exploration.”
Assays for the program are handled by ALS Laboratories in South Africa, an ISO/IEC 17025-accredited facility. Sample preparation involves crushing to 70% passing 2 mm, riffle splitting, and pulverizing a 250g split to 85% passing 75 microns. Gold analysis is conducted via 30g fire assay with atomic absorption finish (method Au-AA25), with samples above the upper detection limit re-assayed by gravimetric finish. Multi-element analysis utilizes a four-acid digestion with ICP-AES finish (method ME-ICP61a) for a 33-element suite. Quality assurance and control measures include certified reference materials spanning the expected grade range, blanks for contamination monitoring, and field duplicates inserted into the sample stream, with chain of custody maintained from collection to laboratory.
