Galiano Gold Advances Towards a Maiden
Underground Resource at Abore with
Additional High-Grade Results Encountered
Including 4.7 g/t Au over 28m and 3.5 g/t Au
over 17m
New high grade drilling intercepts to be included in maiden
underground Mineral Resource
Vancouver, British Columbia--(Newsfile Corp. - November 17, 2025) -
Galiano Gold Inc. (TSX: GAU)
(NYSE American: GAU) ("Galiano" or the "Company")
is pleased to provide an update on the 2025
Abore drilling program, currently underway at the Asanko Gold Mine ("AGM"), in Ghana, West Africa.
The latest drilling results continue to confirm multiple significant high-grade intercepts, demonstrating
continuity of mineralization within new ore shoots identified in 2025 that lie below the existing Mineral
Reserve and Mineral Resource. Continued drilling success has prompted an expansion of the 2025
Abore drilling program by a further 11,000 meters ("m") demonstrating the Company's strategic focus on
increasing Abore's Mineral Resource.

Chris Pettman, Galiano Gold's Vice President of Exploration, stated: "We are very pleased with the
progress at Abore as we continue to intercept high-grade mineralization across the deposit. These latest
drill results further confirm the potential for Abore to host meaningful underground Mineral Resources and
therefore redefine the long-term future of the AGM. These results, along with the expanded infill and step
out drilling program, will be used to define a maiden Mineral Resource, expected in February 2026."
Current Results
The most recent results are part of the ongoing Abore drilling campaign that began in Q2 2025 and will
now continue through the end of Q4 2025 and into 2026.
Based on the positive drilling results to date
1,2,3
the current Abore drill program is focused on rapidly
infilling areas immediately below the Abore Mineral Reserve and Mineral Resource to expand the
Inferred and Indicated Mineral Resource, as well as to test for further continuations of mineralization
down plunge and below known mineralized zones.
Continuity of High Grades below Main and South Pits and within the saddle zone
The most recent drilling at Abore is focused on infilling gaps within the recently discovered
ore-shoots below the Mineral Resource. Current results have confirmed high-grade
mineralization has excellent continuity within the north plunging ore shoots below both the
South pit and Main pit, as well as within the saddle zone between the two pits where a
conjugate south plunging structure also carries high grade mineralization. These zones
combined have been confirmed to span approximately 800m in strike length and carry
grades expected to support underground mining.
North High Grade Zone
Step out drilling in the vicinity of previously announced hole ABDD25-388 which intercepted
high grade mineralization at North pit has also intercepted additional high-grade
mineralization in hole ABDD25-411 returning
24.6m @ 2.0 g/t, including 17.6m
@ 2.63 g/t
and providing valuable structural information which will help inform further drilling designed to
expand this high-grade zone.
Extension at Depth
In addition to infill drilling within the known mineralized zones, the current program aims to
test for extensions of mineralization below these zones. Hole ABDD25-398 was designed to
test the area below the Main pit ore shoot and successfully intercepted 60.5m of granite with
strong mineralization returning
18.6m @ 1.6 g/t Au from 409m and 5m @ 1.6 g/t Au from
361m
at the granite-sediment contact along with strong alteration and quartz veining known
to accompany high-grade mineralization at Abore. This mineralization remains open in all
directions and is very encouraging as the current drilling continues to test deeper
underground Resource targets.
Next Steps
The Board of Directors has approved an additional budget of
$3.1M for a further 11,000m
of drilling to
be completed at Abore by the end of 2025. Key objectives of the increased budget include:
Further delineate continuity of high-grade mineralized zones identified in Q3 2025.
Increase drilling density to convert zones of Inferred Resources to the Indicated category.
Test for further extensions of mineralization along strike and plunge of known ore zones
below the Mineral Resource.
Step-out drilling below known mineralization to test for further expansions of the Abore
mineralizing system.
Resource Expansion
:
Cut-off date of January 5,2026 has been set for delivery of new exploration data to support
updated Mineral Resource and Mineral Reserve statement ("MRMR") to be released in
February 2026.
Maiden Underground Resource
:
Drilling completed ahead of MRMR cut-off date will be incorporated into a maiden
underground Mineral Resource at Abore to be released as part of the updated MRMR in
February 2026.
Abore 2025 Drilling Overview
Since January 2025, over 22,000m of drilling has been completed at Abore and includes:
Phase 1
: consisted of 5,543m and was completed in May 2025, designed to test for extensions of
mineralization immediately below the existing Mineral Resource. This initial drilling resulted in the
discovery of a new high-grade zone under Main pit as well as multiple new high-grade intercepts
under South pit.
1
First Deep Test
: An initial test for deeper mineralization consisting of 1,907m was completed in
July, 2025.
These four holes all intersected mineralized granite with three holes returning significant
widths and grades.

Phase 2:
Following positive results from Phase 1, a Phase 2 program commenced in June 2025
consisting of 10,000m of drilling designed to test for extensions of mineralization identified in
Phase 1 and expand drilling across the entire 1,800m strike length. This drilling returned
exceptional results, identifying multiple high-grade ore shoots under South and Main pits, as well
as the discovery of a new high-grade zone under North pit. The initial drill plan for this phase was
subsequently expanded to a total of 14,687m drilled.

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, 2024

.
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.
