“We are excited to see consistent high-grade zones intercepted below the current resource shell at grades
significantly above the average grade of the existing mineral resource,” said Matt Badylak, President and
Chief Executive Officer of Galiano. “We recognise the significance of encountering grades of this
magnitude and continuity of mineralization at these elevations and anticipate these results will drive near
term value through open pit resource expansion, while providing robust targets for continued exploration
success at Abore.”
Chris Pettman, Galiano's Vice President of Exploration, added: "These results validate our exploration
strategy and strengthen our confidence in Abore as we advance with expanded drill programs targeting
both open pit extensions and underground potential. We anticipate continuing aggressive drilling
operations at Abore for the balance of the year and into 2026."
Abore 2025 Phase 2 Program Overview
Following the positive results of a Phase 1 drilling program reported in Q1 2025, which targeted
mineralization within and directly below the Mineral Reserve pit1, the Company is pleased to report partial
results on Phase 2 currently underway at Abore and near 75% complete.
The Phase 2 program was designed to test for further extensions of mineralization immediately below the
Abore Mineral Reserve and Mineral Resource, across a strike length of approximately 1,600m, extending
to the northern end of the Abore Mineral Reserve pit. Drilling has progressed under budget and ahead of
schedule and is now expected to achieve approximately 10,000m over 40 holes. Complete assays have
been received for 31 holes to-date.

Abore South and Abore Main: Multiple High-Grade Ore Shoots Identified
Among the highest priorities for the Phase 2 program was testing for continuation of mineralization in the
‘saddle’ area between Abore South pit and Abore Main pit, as well as expanding the high-grade zone
initially discovered during Phase 1 drilling, where hole ABPC25-346 (the “Discovery Hole”) returned 50m
@ 3.2 g/t Au under the south end of Abore Main pit1.
Drilling from Phase 2 has confirmed mineralization continues along a low angle ore shoot, down plunge
and along strike, to the north of the known south high-grade zone into the saddle area. This high-grade
zone now has a total strike length of approximately 400m, with notable intercepts including:
Hole ABDD25-354: 17.5m @ 3.0 g/t Au from 241m
Hole ABPC25-361: 19.9m @ 2.3 g/t Au from 215m
The high-grade zone at the south end of Abore Main pit mentioned above has now been shown to be part
of another low angle, north plunging ore shoot also extending over at least 400m. It starts 60m along
strike and up plunge to the south of the Discovery Hole, where Phase 2 drilling intersected the ore shoot
under the saddle area and returned the following significant intercept:
Hole ABPC25-380 30.6m @ 2.9 g/t Au from 148m, including 17m @ 4.5 g/t Au
Multiple drill holes intercepted the down plunge extension of this ore shoot under Abore Main pit to the
north of the Discovery Hole, including the following key intercepts:
Hole ABPC25-371: 29.7m @ 2.9 g/t Au from 209m
Hole ABDD25-374: 46m @ 1.7 g/t Au from 225m, including 13m @ 2.8 g/t Au
Hole ABDD25-376: 40m @ 2.1 g/t Au from 208m, including 12m @ 3.8 g/t Au
Hole ABDD25-377: 34m @ 1.6 g/t Au from 210m, including 8m @ 3.7 g/t Au
Hole ABDD25-379: 30m @ 1.3 g/t Au from 233m, including 5m @ 3.2 g/t Au
This ore shoot remains open along strike and down plunge to the north under Main pit, as well as at depth.
Drilling during Phase 2 in the area under the saddle, between Abore South pit and Abore Main pit, has
also identified what is interpreted as a south dipping conjugate structure carrying high-grade
mineralization that connects the two north plunging ore shoots, with the following significant intercept:
Hole ABDD25-384: 16.4m @ 5.3 g/t Au from 189m
Other intercepts of note at Abore South pit include a wide intercept of mineralized granite directly below
the south high-grade zone, with hole ABPC25-368 intercepting 44.8m @ 2.0 g/t Au from 279m, including
17m @ 3.3 g/t Au . The southern most hole of the Phase 2 program, hole ABPC25-364, intercepted 28m
@ 1.6 g/t Au from 207m.

Abore North: New High-Grade Zone Discovered
Phase 2 drilling extended to the northern end of the deposit, identifying a new high-grade zone located
approximately 75m below the Abore Mineral Resource under Abore North pit, with the following
significant intercept:
Hole ABDD25-388: 23m @ 6.8 g/t Au from 240m
Further infill drilling around this intercept is currently underway to determine the orientation and size of
this new zone, which remains open along strike to the north and south, as well as at depth. In addition to
this newly discovered high-grade zone, Phase 2 drilling, under and around North pit and below the Mineral
Resource, has returned additional well-mineralized intercepts including:
Hole ABPC25-375: 11m @ 2.3 g/t Au from 189m and 7m @ 2.6 g/t Au from 208m
Hole ABDD25-387: 5.2m @ 5.5 g/t Au from 266m and 5m @ 3.0 g/t Au from 279m and 5m @ 2.0
g/t Au from 292m
These strong initial results demonstrate that there is considerable near-term growth potential at Abore
North, where active mining has yet to begin.
The current Phase 2 program remains ongoing with 9 holes from Abore South, Abore Main and Abore
North yet to be completed and/or awaiting final assays.
Next Steps
Based on the continued exploration success at Abore, the 2025 drilling campaign will now be expanded
beyond the completion of the current Phase 2 program and is anticipated to extend into 2026 to rapidly
increase drill density within the zone immediately below the current Abore Mineral Resource with the
goal of growing Inferred and Indicated Mineral Resources. The program will also continue to aggressively
test multiple priority targets for further continuations of high-grade mineralization along plunge and
beneath the known mineralized zones, which all remain open.
Key areas of strategic interest include the 'saddle' zone connecting the Abore South and Main pits, as well
as sections directly below the North pit, which present compelling mine optimization opportunities.
Mineralization remains open at depth and across the entire 1,800m of strike of the Abore deposit. The
Company is undertaking studies to evaluate underground mining potential and to define the optimal
transition depth between open pit operations and potential future underground development.
The exploration team at the AGM is well positioned to execute this aggressive drilling strategy with a fully
staffed, highly skilled team on site, sufficient funding, and the full support of the Company’s management
and Board of Directors. As demonstrated during the ramp up of the Phase 2 drilling, the Company was
able to leverage strong relationships with our in-country drilling contractors to obtain high quality
equipment and crews and plan to ramp up to a minimum of five to six drill rigs at Abore throughout the
duration of this next phase of drilling.

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.
