One Bullion Reports High Concentration of Gold During Artisanal Sampling Program at Vumba Project Which Yielded a 679 g/t Gold Sample

Executive Summary of Recent Release

• One Bullion Ltd. reported high-grade gold surface grab samples from artisanal sampling at the Vumba Project in Botswana on April 27, 2026.
• The headline sample returned 679 g/t Au, with additional samples ranging from >10.0 g/t to 207 g/t Au.
• The program investigated seven historical artisanal workings and identified three previously unrecognized workings with anomalous gold values.
• Mineralization is hosted in smoky quartz veins within amphibolite gneiss and schist, interpreted as structurally controlled orogenic gold systems.

News vs. Market Expectations

• The 679 g/t sample is significantly higher than historic surface samples disclosed in January (e.g., OB1080 – 116 g/t Au), representing a material improvement in grade perception.
• However, the news is classified as Routine - Positive because it follows the planned exploration cycle announced in January and does not constitute a resource definition or drilling result.
• The market has already reacted negatively to previous updates, with the stock price declining from $2.60 in December 2025 to $0.40 by April 2026 despite positive exploration news.
