One Bullion Reports Significant Historical Gold Results and Advances Exploration at Vumba

Mine or Deposit Published Figures Date and Reporting Basis Blanket Gwanda belt Underground M&I: 17.674 Mt at 3.83 g/t; 2.178 million oz. Inferred: 6.940 Mt at 3.35 g/t; 748,000 oz. Effective 30 June 2026; 100% project basis. Underground resources include reserves. [1] Mupane Tati belt M&I: 5.166 Mt at 1.42 g/t; 235,800 oz. Inferred: 4.378 Mt at 1.35 g/t; 190,700 oz. P&P reserves: 1.810 Mt at 2.07 g/t; 120,200 oz. Effective 31 December 2021; historical inventory. Resources exclude reserves. Main resource inventory excludes slimes and includes a small stockpile. [2] Vubachikwe Gwanda belt 1.04 million oz of reported historical gold production. Historical production account reproduced in the 2017 Blanket technical report. [3] Jessie Gwanda belt 12 tonnes of reported historical gold production, approximately 386,000 oz. Historical production account reproduced in the 2017 Blanket technical report. [3] Freda Gwanda belt 7,550 kg of reported historical gold production, approximately 243,000 oz. Historical production account reproduced in the 2017 Blanket technical report. Freda in Gwanda, distinct from Freda Rebecca. [3] M&I = measured and indicated; P&P = proven and probable; Mt = million tonnes; oz = troy ounces. Inferred resources are shown separately. Production, resources and reserves describe different quantities and have not been combined. The Mupane figures are historical and do not represent a current remaining inventory; Golden Eagle is included in that inventory. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

All lengths are downhole; true widths are unknown. “Including” rows lie within the preceding parent interval and are not additional meters. Reported composites are length-weighted averages that include lower-grade internal samples. Gold grades are rounded to two decimal places. The SD071 composite is strongly influenced by the 1.0 m sample at 101.81 g/t gold. The VUDD005 and VUDD016 results shown use the reported gravimetric determinations.

Sampled lengths are not established true widths. VUT004’s included 2.5 m interval uses the reported gravimetric assays; the 3.5 m parent interval also includes the adjoining 1.0 m sample grading 0.469 g/t gold. These are selected results and do not represent the average grade of the property.
