Botswana Gold Mine Completes Processing of 11,654 Line-Kilometers of Airborne Geophysical Data

en.Wedoany.com Reported - On October 14, Canadian mineral exploration company One Bullion announced that it has received the final processed data from the 2026 high-resolution airborne geophysical survey at its Maitengwe Gold Project in Botswana. This survey covered a 58,075-hectare mineral rights area, with a cumulative total of 11,654 line-kilometers of airborne surveying completed at a line spacing of 50 meters. Meanwhile, the company's Vumba Gold Project in Botswana has completed three new diamond drill holes and is advancing an annual drilling program totaling approximately 3,000 meters.

The Maitengwe airborne geophysical survey was conducted by Xcalibur Smart Mapping, with field data acquisition completed between July 7 and 30 using a fixed-wing Air Tractor aircraft. Campbell & Walker Geophysics was responsible for the post-processing and preliminary interpretation of magnetic and radiometric data. The project's technical team is currently integrating magnetic gradient, radiometric, historical geological, geochemical, and structural data to identify concealed stratigraphy, structural corridors, lithological contact zones, and magnetic anomaly boundaries beneath the Kalahari sand cover, and to prioritize follow-up drill targets.

The Vumba project utilizes HQ-size diamond drilling. The completed drill holes VUDD017 and VUDD018 are located in the Vumba Central target area, with azimuths of 269° and 330° and dip angles of -58° and -60°, respectively. Preliminary core logging recorded amphibolite-dominated stratigraphy, along with silicification-carbonate alteration, quartz-carbonate veins, and localized sulfides. The two drill holes were designed to establish a primary geological cross-section and to test branch faults, structural intersections, and vein stacking, respectively.

Drill hole VUDD019 is located in the North Main deep target area, with a final depth of 315 meters, a drilling azimuth of 267°, and a dip angle of -69°, designed to test the deep extension of the identified mineralized structural corridor. The follow-up drill hole VUDD020 has commenced at Vumba Central, using an azimuth of 267° and a dip angle of -69° for deep testing. The company also plans to drill hole VUDD021 to conduct extensional exploration along the northern part of the mineralized structure, in order to obtain geological data on the strike and deep continuity of mineralization.

Core from the Vumba project is being logged, photographed, cut, and sampled, with analysis planned on a nominal one-meter sample basis, adjusted according to geological contact boundaries. Samples from drill hole VUDD017 have been delivered to ALS Laboratories in South Africa, with preliminary assay results expected approximately 14 days after October 14. Testing employs a 30-gram sample fire assay with atomic absorption analysis, along with four-acid digestion and inductively coupled plasma atomic emission spectrometry for multi-element determination. Samples with gold grades exceeding 10 g/t are planned for gravimetric re-analysis.
