11,654 Line-km Survey at 50-m Spacing Advances Target Generation Beneath Kalahari Cover
VUDD019 Tests the North Deep Corridor Before Drilling Returns to Vumba Central
TORONTO, Oct. 14, 2026 (GLOBE NEWSWIRE) — One Bullion Ltd. (“One Bullion” or the “Company”) (TSXV: OBUL), a gold exploration company holding complete ownership of three prospective exploration projects in Botswana, today announced receipt of the final processed dataset from its 2026 high-resolution airborne geophysical survey at the Maitengwe Gold Project and provides an update on the ongoing approximately 3,000-meter HQ diamond drilling program at the Vumba Gold Project.
Highlights
- The Maitengwe airborne survey covered 11,654 line kilometers at 50-meter line spacing across the two licenses comprising the 58,075-hectare project.
- Final magnetic gradient and radiometric products are being integrated with historical geological, geochemical and structural information to refine and rank drill targets beneath extensive Kalahari cover.
- At Vumba, VUDD017 and VUDD018 were completed at the Vumba Central target to establish the principal geological and structural framework from two different drilling orientations.
- VUDD019 was drilled at the North Main deep target, a previously defined priority position within the Company’s 2026 technical drill plan, providing an early deep test of a second established mineralized corridor.
- Following VUDD019, drilling is planned to return to Vumba Central with VUDD020, the deeper Central test, followed by VUDD021, a northern step-out intended to test continuity and scale.
- VUDD017 samples are currently being processed at ALS Laboratories in Johannesburg, with initial analytical results expected within approximately 14 days, subject to laboratory turnaround, QA/QC verification and Qualified Person review.
- No assay results from the current Vumba drilling are reported in this release; visual geological observations do not establish gold grade, true width, continuity or economic significance.
“The completed Maitengwe survey and the ongoing Vumba drilling program are advancing two complementary exploration workstreams in Botswana,” said Adam Berk, Chief Executive Officer of One Bullion. “At Maitengwe, the new high-resolution dataset provides a project-scale structural framework beneath extensive cover. At Vumba, the first two holes have established complementary structural sections at Vumba Central, VUDD019 has provided an early deep test at North Main, and the drill is planned to return to Central for deeper and step-out testing. Laboratory assays remain essential to determine the significance of the alteration, veining and sulfides observed in core.”
Maitengwe Airborne Geophysical Survey
The Company has received the final processed products from the high-resolution airborne survey completed over the Maitengwe Gold Project. Xcalibur Smart Mapping acquired the dataset using a fixed-wing Air Tractor platform between July 7 and July 30, 2026. Campbell & Walker Geophysics completed post-processing and preliminary interpretation of the magnetic and radiometric data.
Maitengwe is extensively covered by Kalahari sands, limiting direct geological and structural mapping at surface. The survey products assist in mapping concealed stratigraphy, structural corridors, contacts, magnetic breaks and other features that may support future target generation. The technical team is integrating the new geophysical products with the Company’s historical geological, geochemical and structural datasets to rank prospective areas for follow-up work and future drilling.

Vumba Drilling Program Update
The Company continues its approximately 3,000-meter HQ diamond drilling program at Vumba. VUDD017 and VUDD018 were completed at Vumba Central to provide two complementary views of the interpreted structural corridor. Preliminary logging from those holes records an amphibolite-dominated sequence with variable foliation and banding, repeated silica-carbonate alteration, quartz-carbonate veining and locally observed sulfides. These observations are preliminary and do not establish gold grade or economic mineralization.
VUDD019 was drilled from the North Main deep target at 535753 mE / 7713970 mN (WGS84 / UTM Zone 35S) to a depth down-hole of 315 meters. This collar corresponds to a previously identified deep-continuity target within the Company’s 2026 technical drill plan. The hole provides a deep geological test beneath the established North Main corridor while logging, sampling and laboratory work continue on the Vumba Central core.
| Hole | Target | Status / Collar Azimuth / Dip |
Technical Role |
| VUDD017 | Central | Completed 535976 E / 7712693 N 269° / -58° |
Anchor hole establishing the principal lithological, alteration and structural section. |
| VUDD018 | Central | Completed 535894 E / 7712640 N 330° / -60° |
Oblique structural test across splays, intersections, vein stacking and possible shoot controls. |
| VUDD019 | North | Completed 535753 E / 7713970 N 267° / -69° |
Deep test beneath the North Main corridor; final survey and EOH reconciliation in progress. |
| VUDD020 | Central | Drilling 536015 E / 7712800 N 267° / -69° |
Deeper Central test intended to assess continuity of the hydrothermal and structural system at depth. |
| VUDD021 | Central | Planned 536115 E / 7712866 N 270° / -60° |
Northern step-out intended to test strike/down-plunge continuity and scale. |

Sampling, Analysis and QA/QC
Core from the current Vumba program is being logged, photographed, cut and sampled at the Company’s secure core facility. The Company intends to sample the full holes at nominal one-meter intervals, adjusted to geological contacts. Certified reference materials, blanks and duplicates are included in the QA/QC stream. Samples are transported under chain-of-custody procedures to ALS Laboratories in South Africa, an ISO/IEC 17025-accredited laboratory independent of the Company. Gold analysis is planned by 30-gram fire assay with atomic absorption finish (Au-AA25), together with multi-element analysis by four-acid digestion and ICP-AES (ME-ICP61a). Samples returning more than 10 g/t gold are planned for gravimetric-finish re-assay (Au-GRA21), with additional checks determined by the technical team and laboratory.
Samples from VUDD017 have been received by ALS Laboratories in Johannesburg and are currently being processed. Based on the laboratory’s current indicated turnaround time, the Company expects to receive initial analytical results within approximately 14 days. The timing remains subject to laboratory throughput, completion of the Company’s QA/QC review, any required repeat or over-limit analyses, and review by the Qualified Person. Verified results will be disclosed as soon as practicable thereafter.
Next Steps
- Complete detailed interpretation and target ranking using the final Maitengwe magnetic and radiometric dataset.
- Complete logging, sampling, survey reconciliation and laboratory submissions for the Vumba holes drilled to date.
- Return drilling to Vumba Central with VUDD020, followed by the planned VUDD021 northern step-out, subject to final technical release controls.
- Integrate verified geological, structural, geochemical and assay information into the three-dimensional Vumba model before subsequent drilling decisions.
Cautionary Note Regarding Visual Observations
No assay results from VUDD017, VUDD018 or VUDD019 are reported in this release. Visual identification of alteration, sulfides and quartz-carbonate veining is preliminary and is not a substitute for laboratory analysis. These observations do not establish gold grade, true mineralized widths, continuity or economic significance. Final collar, end-of-hole and downhole survey data must be reconciled in the project database before final spatial interpretation.
