GALIANO GOLD EXPANDS ABORE HIGH-GRADE FOOTPRINT
WITH MULTIPLE INTERCEPTS IN LATEST DRILLING INCLUDING
14.2 g/t Au OVER 15m and 4.7 g/t Au OVER 24m
New high-grade intercepts expand mineralized footprint well below existing drilling, results will be
included in upcoming Abore maiden underground Mineral Resource
Vancouver, British Columbia, January 29, 2026 – Galiano Gold Inc. (“Galiano” or the “Company”) (TSX,
NYSE American: GAU) is pleased to report the latest results of the 2025 Abore drilling program, which
was completed in December 2025 at the Asanko Gold Mine (“AGM”) in Ghana, West Africa. Multiple
intercepts demonstrate continuity of high-grade zones and step out drilling confirms new high-grade
mineralization up to 200 meters (“m”) below previous holes. These results demonstrate the robustness
of Abore’s underground potential and will be included in the maiden Abore underground Mineral
Resource estimate expected to be released in February 2026.
This News Release highlights results from the expanded Abore Phase 2 drilling campaign announced in
November of 2025 1 designed to prove continuity of known mineralization, as well as to test for
continuations of the Abore mineralizing system at depths up to 200m below previous drilling. The AGM
exploration team successfully completed the 11,000m program in December 2025, enabling all results
to be included in the upcoming Abore Mineral Resource update.
Selected Drill Highlights (see notes 3,4,5 from Table 1):
Hole ABDD25-431: 14.2 grams per tonne (“g/t”) gold (“Au”) over 15m from 231m
Hole ABDD25-444: 4.4 g/t Au over 30m from 306m
Hole ABDD25-453: 30.4 g/t Au over 4m from 500m
Hole ABDD25-428: 2.5 g/t Au over 45m from 213m
Hole ABDD25-429: 4.7 g/t Au over 24m from 151m
Hole ABDD25-448: 3.0 g/t Au over 11m from 480m and 3.4 g/t Au over 15m from 496m and 2.5
g/t Au over 27m from 529m
Hole ABDD25-443: 2.3 g/t Au over 23m from 401m
Hole ABDD25-447: 2.3 g/t Au over 19m from 247m
Chris Pettman, Galiano's Vice President of Exploration, stated: “These latest results conclude an extremely
successful year of discovery at Abore in 2025 that has seen the deposit emerge as a key growth target for
the AGM. This latest phase of drilling highlights that the Abore mineralizing system is much larger than
previously believed and remains open as we continue to step out and intersect mineralization at depth. I
am also proud of the AGM exploration team as they were able to safely and efficiently deliver these
11,000m within six weeks, in time for inclusion in the upcoming maiden underground Mineral Resource.”

Current Abore Drilling Results
High-Grade Continuity
Infill drilling at Abore South pit has returned multiple high-grade intercepts, which further confirm the
robust nature and continuity of high-grade mineralization in this zone. Highlighted intercepts include:
24m @ 4.7 g/t Au from 151m in hole ABDD25-429
15m @ 14.2 g/t Au from 223m in hole ABDD25-431
17m @ 1.7 g/t including 6m @ 3.6 g/t Au from 196m in hole ABDD25-436
15m @ 2.1 g/t Au from 122m in hole ABDD25-437
At Abore Main pit, current drilling has both infilled and expanded the known high-grade zones with
multiple intercepts of high-grade mineralization, increasing the vertical extent of the Main pit ore shoot
by at least 50m. Additionally, hole ABDD25-444 returned intercepts of 30m @ 4.4g/t Au from 306m and
18m @1.95 g/t Au from 282m. These intercepts are particularly encouraging as they occur north of a
known and typically barren structural break in the host granites and display the same alteration, veining
and sulphide related mineralization that characterizes the highest grade mineralization in other areas of
the deposit.

Two infill holes at Abore North pit also intersected strong mineralization with hole ABDD25-424
returning 34m @ 2.0 g/t Au from 254m, and hole ABDD25-44 returning 19m @ 2.3 g/t Au from 247m
and 8m @ 3.2 g/t Au from 287m, further demonstrating the potential for growth of the high-grade zone
at the northern end of the Abore deposit.
Step Out Drilling at Depth
As part of this phase of drilling, four step out holes were drilled to test for the extensions of the Abore
mineralizing system up to 200m below previous drilling. All four holes intersected mineralization, with
two holes below Abore Main pit returning significant high-grade intercepts. Hole ABDD25-448
intersected 11m @ 3 g/t Au from 480m, 15m @ 3.4 g/t Au from 496m and 27m @ 2.5 g/t Au from 529m
and hole ABDD25-453 returned 4m @ 30.4 g/t Au from 500m, as well as 26m of lower grade
mineralization.
Hole ABDD25-452 was drilled to similar depths below Abore South pit and intersected 50m of the Abore
granite which is the primary host of Abore mineralization. The intercept carries a lower grade zone of
mineralization ranging from 0.9 g/t Au to 1.5 g/t Au, but is characterized by high density quartz veining,
brecciation, alteration, and sulphides that is typically associated with Abore style mineralization.
These results are highly encouraging as they demonstrate that the Abore system and associated high-
grade mineralization remains open at depth across the entire 1.8 kilometres of strike length of the Abore
deposit.
2026 Exploration
Following a very successful 2025 program, exploration efforts at the AGM in 2026 will be focused on
supporting a revised Life of Mine plan and Mineral Reserve and Mineral Resource update anticipated in
2027. An initial 2026 exploration budget of $17 million has been approved by the Galiano Board of
Directors.
Exploration activities will be heavily focussed on delivering near term value through Mineral Resource
and Mineral Reserve growth within the brownfields space, while simultaneously continuing to advance
the greenfields generative portfolio at the AGM with early stage work and drill testing at numerous high
priority regional targets.
The necessary drill rigs and crews were secured ahead of the end of 2025, allowing the 2026 exploration
program to begin quickly in the first week of January 2026. Drilling is already underway at Abore, with
four rigs currently active. An additional three to four rigs will be added as an infill drilling program at
Esaase is expected to commence later in the first quarter of 2026.

Priority Resource and Reserve Growth Programs
Abore
An aggressive program of 30,000m of drilling is planned at Abore in 2026 with three primary goals:
Continue to grow the underground Mineral Resource through step out drilling to at least 200m
below the maiden Mineral Resource, expected to be released in February 2026.
Selective infill drilling to prove continuity of mineralization and convert and upgrade Mineral
Resource categories in support of a potential maiden underground Mineral Reserve in 2027.
Flexibility to step out and test for mineralization at deeper elevations based on results as drilling
progresses.
Esaase
A phased program of infill drilling is planned for Esaase through 2026 which is designed to convert
existing open pit Mineral Resources from Inferred to Indicated category to significantly increase the
Esaase Mineral Reserve and support planning of potential future open pit expansions.
Phase 1 of drilling, consisting of approximately 9,000m focused on the main Esaase pit, is
scheduled to commence in February 2026.
Results from Phase 1 will inform the potential continuation of the Esaase program up to an
additional four phases to be completed in 2026 ahead of the 2027 Mineral Resource and Mineral
Reserve update in 2027.
Background
Abore is located approximately 13 kilometers north of the AGM’s processing plant, directly along the haul
road, and has current Measured and Indicated Mineral Resources of 638,000 ounces at 1.24 g/t Au and
Inferred Mineral Resources of 78,000 ounces at 1.17 g/t Au, as published in the Company’s most recent
Mineral Reserve and Mineral Resource estimates effective December 31, 20242.
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.
