Galiano Gold Inc.

Background

Abore is located approximately 13 kilometers north of the AGM's processing plant, directly along the haul road, and has current Open pit Measured and Indicated Mineral Resources of 388,000 ounces at 1.15 g/t and underground Measured and Indicated Mineral Resources of 139,000 ounces at 2.2 g/t Au as well as underground Inferred Mineral Resources of 165,000 ounces at 2.2 g/t Au, as published in the Company's most recent Mineral Reserve and Mineral Resource estimates effective December 31, 20252.

The Abore deposit sits along the Esaase shear corridor, which also hosts the Esaase deposit, and forms part of the northeast striking Asankrangwa gold belt. The geology of Abore is characterized by a sedimentary sequence composed primarily of siltstones, shales and thickly bedded sandstones that has been intruded by a granite, which lies parallel to the shear and dipping steeply to the northwest. The majority of mineralization is constrained to the granite, hosted in west dipping quartz vein areas developed primarily along the eastern margin of the granite/sediment contact.
