GALIANO GOLD ANNOUNCES SIGNIFICANT DRILL RESULTS FROM ABORE, INCLUDING 45m @ 12.4 g/t Au & 37m @ 10.6 g/t Au

VANCOUVER, BC, March 11, 2024

The Abore infill drilling programme consisted of 84 holes totalling 22,470 metres. It was designed to convert Inferred Mineral Resources below the current Mineral Reserve pit shell¹ to the Indicated Mineral Resource category and evaluate the potential to optimize and/or expand the pit. Earlier positive results from this campaign were highlighted in a news release "Galiano Gold Provides Asanko Gold Mine 2023 Exploration Program Update" (see press release dated October 25, 2023).

This program resulted in the discovery of a new high grade zone within the southern portion of Abore which was intersected in four drill holes over approximately 120 metres of strike length as shown in a series of cross sections in Figures 2 to 5 below. Intercepts in this zone are amongst the best ever intercepted at the AGM and include:

• Hole ABPC23-224: 45 metres @ 12.4 g/t gold from 191m
• Hole ABPC23-226: 37 metres @ 10.6 g/t gold from 199m
• Hole ABPC23-239: 54 metres @ 3.3 g/t gold from 207m 
• Hole ABPC23-228: 41 metres @ 3.3 g/t gold from 191m

This new zone of mineralization is hosted primarily within the Abore granite and is characterized by significant hydrothermal alteration along with high density quartz veining, intense localized brecciation, disseminated arsenopyrite and visible gold. It remains open along strike in both directions and is untested at depth. A follow-up drill program is currently underway to test the extent of this zone.

Robust mineralization was also intersected across the deposit as demonstrated by the following highlighted intercepts:

• Hole ABPC23-246: 18 meters @ 8.2 g/t gold from 172m 
• Hole ABPC23-259: 24 meters @ 5.4 g/t gold from 263m 
• Hole ABPC23-223: 27 meters @ 4.2g/t gold from 246m
• Hole ABPC23-228: 41 metres @ 3.3 g/t gold from 191m
• Hole ABPC23-213: 20 meters @ 4.5 g/t gold from 166m
• Hole ABPC23-241: 23 meters @ 3.8 g/t gold from 156m 
• Hole ABPC23-249: 19 meters @ 4.0 g/t gold from 273m 

"These excellent results demonstrate that Abore has significant upside potential beyond the current Reserves," stated Chris Pettman, Galiano's Vice President of Exploration. "Seeing significant intervals of high grade gold along the entire 1,600 metre strike length of the deposit, and the discovery of the new high grade south zone, gives us confidence that Abore will continue to grow and add considerable value to the AGM life of mine."

Matt Badylak, Galiano's President and Chief Executive Officer added, "The results of this program are expected to affect the size and geometry of the Abore Reserve pit. The impact this will have on Mineral Reserves and ore delivery in 2024 is currently being evaluated through pit optimization and redesign. The Company plans to update Abore Mineral Resources and Mineral Reserves and provide 2024 production and cost guidance following the completion of this work in April."
