ONE BULLION REPORTS HIGH CONCENTRATION OF GOLD DURING ARTISANAL SAMPLING PROGRAM AT VUMBA PROJECT WHICH YIELDED A 679 G/T GOLD SAMPLE

One Bullion Ltd. has completed a targeted geological mapping and sampling program across seven identified artisanal workings within the Vumba project.

"These results validate our geologic thesis at Vumba and give us increased confidence that we are dealing with a meaningful mineralized corridor that warrants follow-up drilling," said One Bullion's chief executive officer, Adam Berk. "A cursory, first-pass sampling program has already returned visible gold and a headline grade of 679 g/t within a documented mineralized corridor, at grades not previously observed in this area. These results, combined with the high-resolution airborne geophysical survey soon to be under way, position One Bullion to rapidly refine drill targets and advance the Vumba licence through 2026."

This initial program marks the start of One Bullion's 2026 exploration program and is designed to advance the company's geologic understanding of the property through increased surface exposure and sampling. This program allows for further evaluation of the gold potential beyond the company's previously trenched and drilled areas supporting a broader assessment of the Vumba property. Although several of the artisanal workings are near historical trenches and drill holes, three previously unrecognized workings returned anomalous gold values, highlighting additional exploration upside and reinforcing the property's expansion potential. A total of 39 rock samples were collected during the program and have been submitted to ALS Laboratories for geochemical analysis. Veins are hosted in amphibolite gneiss and schist and are characterized by smokey quartz with associated sulphides.

Highlights

• Three new showings identified;
• Seven historical artisanal workings investigated;
• Thirty-nine rock samples collected and submitted for assay;
• Multiple samples exhibited visible gold a strong indication of high-grade mineralization, particularly sample Z4624;
• Selective grab samples returned grades up to 679 grams per tonne Au (sample Z4624) and 207 g/t Au (sample Z4619); five additional samples returned greater than 10 g/t Au by fire assay and have been submitted for gravity-finish reassay;
• Visible gold and sulphide mineralization observed in several of the quartz veins sampled.

Field observations

Geological mapping and sampling identified multiple occurrences of quartz veining containing sulphides. Visible gold was observed in multiple samples supporting the very high-grade assay results. This program has demonstrated qualitative confirmation of mineralization across the property and particularly new zones of mineralization outside of previously identified mineralized zones.

Geological interpretation

Mineralization is interpreted to be structurally controlled and associated with quartz vein hosted within the broader greenstone belt lithologies. These characteristics are consistent with orogenic gold systems, which are known to host significant gold deposits globally.

The identification of mineralization across approximately 2.5 km of north-south strike supports the company's interpretation of an emerging mineralized corridor at Vumba, warranting follow-up sampling and drill targeting.

Exploration context

This program forms part of the company's broader strategy to expand its exploration footprint and refine drill targeting across the Vumba licence.

The company will integrate these results into the geologic modelling, which will help prioritize follow-up targets for drilling and advance the planning for the next phase of exploration.

Next steps

As previously announced, the company is set to commence a high-resolution airborne geophysical survey across the Vumba licence area, and then subsequently will fly the Maitengwe project to the north. These surveys will be key to the advancement of the company's exploration strategy and will be conducted by Xcalibur Smart Mapping. The surveys are expected to deliver detailed structural and lithological insights to significantly enhance target definition at depth and along strike within the broader greenstone belt. The integration of geophysical data along with this mapping and these assay results will accelerate the refinement and prioritization of high-confidence drill targets, positioning the company to rapidly advance exploration and unlock the full potential of the Vumba mineralized corridor.

Quality assurance/quality control

Rock samples were collected in the field by company personnel and transported under chain-of-custody protocols to ALS Laboratories, an independent certified analytical laboratory. Sample preparation and analysis has been conducted using industry-standard procedures. Analytical testing was performed by ALS Geochemistry (Johannesburg, South Africa), the facility is ISO/IEC 17025:2017 accredited and ISO 9001:2015 certified. The entire sample is crushed to 70 per cent passing two-millimetre mesh, with a 250-gram split pulverized to 85 per cent passing minus 75 micrometres. A four-acid digest is performed on 0.4 g of sample to quantitatively dissolve most geological materials tested using ICP-AES technique. Then 30 grams of the sample material are fire assayed with an atomic absorption finish. Samples that yield results greater than 10 g/t Au undergo an additional test using 30 grams and a gravity finish, which reports up to 10,000 g/t Au with five samples that sampled overlimit still pending final results. All samples disclosed herein were selective grab samples collected from historic artisanal dumps and stockpiles. Grab samples are selective by nature and are not necessarily representative of the overall grade or tenor of mineralization on the property.
