Galiano Gold Inc. (TSX: GAU) (NYSE American: GAU) is pleased to provide an update on the 2025 drilling results at the Abore deposit, following the completion of a planned infill programme. Abore is one of the cornerstone deposits at the Asanko Gold Mine, located in Ghana, West Africa, and is currently being mined by the Company. Highlights of the infill programme include the discovery of a new high-grade zone immediately below the designed Mineral Reserve pit shell at the Abore Main pit and multiple high-grade intercepts surrounding the known Abore South pit high-grade zone.

The 2025 Abore infill drilling programme, consisting of 26 holes totalling 5,543 metres had primary objectives to:

• increase confidence in the existing Mineral Reserve model, focusing on areas throughout the known high-grade zone at Abore South; and
• test for continuations of mineralization below the existing Mineral Reserve pit shell design.

A newly discovered zone of high-grade mineralization, highlighted by hole ABPC25-346: 50m @ 3.2 grams per tonne gold from 100m, was intercepted immediately below the current Mineral Reserve pit design at the southern end of the Abore Main pit. This result provides exciting new targets, along with critical geological and structural information, to guide future drilling aimed at proving further continuations of mineralization at depth.

Drilling in and around the Abore South pit high-grade zone yielded multiple high-grade intervals matching or exceeding the predictions of the Mineral Resource model. These results strengthen confidence in this key portion of the Mineral Reserve, which hosts some of the highest-grade material throughout all of the AGM’s tenements. The drilling program examined areas both within the existing Mineral Reserve pit design and directly beneath it, confirming that mineralization continues uninterrupted and extends beyond the current Mineral Reserve boundaries at Abore South.

Highlights of intercepts at Abore South include (all diamond core samples):

• Hole ABPC25-315: 34 meters @ 12.0 g/t Au from 192m and 11 meters @ 7.2 g/t Au from 239m
• Hole ABPC25-316: 27 meters @ 6.7 g/t Au from 183m
• Hole ABPC25-317: 41 meters @ 3.0 g/t Au from 202m
• Hole ABPC25-324: 27 meters @ 2.9 g/t Au from 232m
• Hole ABPC25-325: 38 metres @ 6.7 g/t Au from 195m
• Hole ABPC25-328: 29 meters @ 3.8 g/t Au from 232m
• Hole ABPC25-329: 23 meters @ 3.1 g/t Au from 120m

High-grade zones throughout the Abore deposit, including this newly discovered zone, display consistent characteristics, with mineralization hosted primarily within the Abore granite, characterized by significant hydrothermal alteration along with high density quartz veining, intense localized brecciation, disseminated arsenopyrite and visible gold.

“The identification of a new high-grade zone beneath Abore Main and the extensions that have grown the Abore South high-grade zone from 90 meters to 180 meters long, underscore the substantial growth potential at Abore,” said Chris Pettman, Galiano’s Vice President of Exploration. “Mineralization remains open at depth throughout the entire 1,600m strike length, with these latest findings suggesting the Abore mineralizing system may be considerably more extensive than previously understood.”

Matt Badylak, Galiano’s President and CEO stated, “These results at Abore validate the robust mineralization within our current open pit reserve, while demonstrating strong potential for transitioning to a higher-grade underground operation through ongoing exploration along strike and at depth. Establishing our first underground resource at the AGM is a strategic priority for 2025. These latest findings position Abore, alongside Nkran, as promising targets for underground mine life extension and a potential source of high-grade mill feed in the future.”

Background

Abore is located approximately 13 kilometres north of the AGM’s processing plant, directly along the haul road, and has current Measured and Indicated Resources of 638,000 ounces @ 1.24 g/t Au and Inferred Resources of 78,000 ounces @ 1.17 g/t Au, as published in the Company’s most recent Mineral Reserve and Mineral Resource update effective December 31, 2024 (see press release “Galiano Gold Announces 2025 Guidance And Provides Mineral Reserve And Mineral Resource Update“ dated January 28, 2025).

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 arrays developed primarily along the western margin of the granite/sediment contact.
