Updated Mineral Reserve Estimate, as of December 31, 2024 Notes: 1. The Nkran, Abore, Adubiaso, Midras South and Stockpiles Mineral Reserves are stated as of December 31, 2024 and the Esaase, Miradani North and Dynamite Hill Mineral Reserves are stated with an effective date of December 31, 2022. 2. Mineral Reserves are reported assuming a gold price of US$1,700/oz for Nkran, Abore, Adubiaso, Midras South and Stockpiles, and US$1,500/oz for Esaase, Miradani North and Dynamite Hill. 3. Mineral Reserves are reported at the point of delivery to the process plant or to stockpile. All tonnages are reported as diluted dry metric tonnes. Mineral Reserves are reported using the 2014 CIM Definition Standards. 4. Mineral Reserves are defined within seven different pit designs guided by pit shells derived from the optimization software, HxGN MinePlan's Minesight Economic Planner, GEOVIA Whittle and Datamine Studio NPVS . 5. Mining cost inputs are in US$/t mined. All other unit cost inputs are US$/t ore. Mining costs vary based on the pit, the rock type, and the depth of the pit. The base mining costs for Nkran, Esaase, Miradani North, Abore, Dynamite Hill, Adubiaso and Midras South are $2.63/t, $1.98/t, $1.94/t, $2.03/t, $2.29/t, $2.03/t, and $2.03/t respectively. There are additional expenditures for fixed contractor monthly fees, grade control, community fees, Owner's Mining G&A, and other small costs that vary with each deposit and are in addition to the $/t stated. 6. Processing cost assumptions for Nkran, Abore, Adubiaso, Midras South and Stockpiles is $10.39/t for oxide ore, $11.25/t for transition ore and $11.52/t for fresh ore, and for Esaase, Miradani North and Dynamite Hill processing cost assumptions are $8.81/t for oxide ore, $10.39/t for transition ore and $10.66/t for fresh ore. 7. General and administration cost assumptions varies by pit and timing with a range in unit costs from $5.17/t to $6.69/t ore. 8. Ore transportation cost varies for each pit based on the haul distance. It ranges between $0.61/t for Nkran and $6.15/t for Esaase. 9. Processing recovery is 94.0% for all ore types in all pits except for Abore and Esaase. Processing recovery for Abore is calculated using a fixed tail of 0.10 g/t but capped to a maximum of 94%. Processing recovery varies based on the ore type and head grade in Esaase, where the average recovery for oxide, Upper Sandstone, Cobra and Central Sandstone ore types are 90.1%, 73.8%, 71.3% and 76.4%, respectively. Processing recovery for existing stockpiles ore is calculated using a fixed tail of 0.10 g/t but capped to a maximum of 85%. 10. Mining dilution varies between pits. The average mining dilution is calculated to be 7.4%, 14.4%, 6.0%, 7.8%, 11.6%, 13.6% and 8.3%, for Nkran, Esaase, Miradani North, Abore, Dynamite Hill, Adubiaso and Midras South, respectively. 11. Mining ore loss varies between pits. The average mining ore loss is calculated to be 3.7%, 2.0%, 2.0%, 6.2%, 2.0%, 3.7% and 11.7%, for Nkran, Esaase, Miradani North, Abore, Dynamite Hill, Adubiaso and Midras South, respectively. 12. The overall strip ratio (the amount of waste tonnes mined for each tonne of ore) for AGM is 7.4 : 1. The strip ratio for Nkran, Esaase, Miradani North, Abore, Dynamite Hill, Adubiaso and Midras South is 13.5, 4.5, 5.6, 5.9, 9.8, 9.3, and 6.9, respectively. 13. Figures are rounded to the appropriate level of precision for the reporting of Mineral Reserves. Due to rounding, some columns or rows may not compute as shown. 14. Mr. Richard Miller, P.Eng., Vice President Technical Services for Galiano Gold Inc., is the Qualified Person responsible for the Nkran, Abore, Adubiaso, Midras South and Stockpiles Mineral Reserves. Dr. Anoush Ebrahimi, P.Eng., Principal Consultant (Mining) SRK (Canada) Inc., is the Qualified Person responsible for Esaase, Miradani North and Dynamite Hill Mineral Reserves. 15. The Qualified Persons are not aware of any mining, metallurgical, infrastructure, permitting, or other relevant factors that could materially affect the Mineral Reserve estimates. 16. Cut-off grades vary based on the deposit and oxidation. All cut-off grades are applied to the fully diluted Au grade. The Mineral Reserves are reported at the following cut-off grades: 1. 0.35 g/t for all Nkran ore 2. 0.40 g/t for all ore types from Adubiaso and Midras South 3. 0.50 g/t for all ore types from Abore, Miradani North, and Dynamite Hill 4. 0.55 g/t for Esaase oxide ore, and 0.70 g/t for the remaining Esaase ore types 15 Deposit Proven Probable Total Proven and Probable Tonnes (Mt) Au Grade (g/t) Au Content (koz) Tonnes (Mt) Au Grade (g/t) Au Content (koz) Tonnes (Mt) Au Grade (g/t) Au Content (koz) Nkran 10.6 1.67 571 10.6 1.67 571 Esaase 13.6 1.22 533 13.6 1.22 533 Miradani North 6.8 1.41 310 6.8 1.41 310 Abore 11.2 1.27 458 11.2 1.27 458 Dynamite Hill 1.1 1.31 45 1.1 1.31 45 Adubiaso 1.5 1.39 67 1.5 1.39 67 Midras South 1.4 1.12 49 1.4 1.12 49 Stockpiles 0.9 0.78 22 0.9 0.78 22 Total Reserve 0.9 0.78 22 46.2 1.37 2,033 47.1 1.36 2,055
