Exploration

 A deep step-out drilling program at the Abore deposit, totaling 1,907m across a 1,200m strike length, yielded

positive results with mineralization intercepted in all four holes, including 36m at 2.5 g/t gold ( refer to news

release dated July 14, 2025).

“We are pleased with the progress made during the period with production, all-in sustaining costs, earnings per

share, and cash balances all improving quarter-on-quarter. This momentum, in combination with the commissioning

of the secondary crusher ahead of schedule in late July, position us well for a strong second half of the year,” said

Matt Badylak, Galiano’s President and Chief Executive Officer, “The results from our Abore deep drilling program

confirm the presence of a mineralized system 200 metres below the current Mineral Reserve over a significant 1,200

metre strike length. These findings highlight the expansion potential at Abore and provide additional exploration

targets to unlock further value beneath our existing reserves.”

Mining

 Development of the Abore pit continued during Q2 2025 with mined ore totaling 0.8 Mt, an increase of 18%

from Q1 2025, at an average grade of 0.9 g/t gold. The strip ratio at Abore was 6.2:1, a decrease of 17% from

Q1 2025.

 Continued mining operations at the Esaase deposit with mined ore totaling 0.5 Mt at an average grade of 0.7

g/t gold and a strip ratio of 5.5:1.

 Mining cost per tonne at Abore and Esaase averaged $3.59 per tonne (“/t”) in Q2 2025 compared to $2.98/t in

Q2 2024 at Abore only. The increase in mining unit rates was due to higher load and haul costs associated with

mining deeper benches, as well as higher drill and blast costs resulting from mining a higher proportion of fresh

granite ore at Abore.

 Continued with waste stripping of Cut 3 at the Nkran deposit with 1.7 Mt of waste rock mined during Q2 2025,

an increase of 113% from Q1 2025. Mined volumes at Nkran are expected to gradually increase as the mining

contractor continues to mobilize most of its mining fleet over the remainder of this year.

 At Nkran, mining cost per tonne was $4.00 for Q2 2025, which included an allocation of general overhead costs.

Nkran waste stripping costs were capitalized as development capital expenditures during the quarter.

Processing

 The AGM produced 30,350 ounces of gold during Q2 2025, an increase of 46% from Q1 2025, as the processing

plant milled 1.2 Mt of ore at an average grade of 0.8 g/t gold with metallurgical recovery averaging 89%. The

increase in gold production was driven by higher plant availability, following the 14-day maintenance shutdown

in Q1 2025, resulting in 10% more tonnes milled in Q2 2025. Gold production in Q2 2025 was also positively

impacted by the high gold-in-process inventory balance that existed at the end of Q1 2025.

 Gold production during Q2 2025 continued to be impacted by lower milling rates, as harder mined ore from

Abore required additional crushing and grinding, compared to softer ore from Esaase that was the primary mill

feed source in Q2 2024. The AGM remains on track to meet the lower end of the production guidance range of

130,000 to 150,000 ounces of gold in 2025.

 The construction of a permanent secondary crushing circuit at the AGM processing plant was completed at the

end of July 2025. As of the date of this news release, the secondary crushing circuit is ramping up to full

capability. The objective of the secondary crushing circuit is to maintain plant throughput at the design capacity

of 5.8 Mt per annum when treating harder ore.

 Processing cost per tonne for Q2 2025 was $12.89, a 10% decrease from Q1 2025. On an absolute basis,

processing costs were consistent quarter-on-quarter. The decrease in processing cost per tonne in Q2 2025 was

driven by 10% more tonnes milled, which decreased fixed processing costs on a per unit basis.

Capital Expenditures

 Sustaining capital expenditures during Q2 2025 totaled $2.2 million and related primarily to a tailings facility

expansion.

 Development capital expenditures, excluding Nkran pre-stripping costs, during Q2 2025 totaled $4.9 million and

related primarily to construction of the now completed secondary crushing circuit.

 $6.9 million in development pre-stripping costs were incurred at the Nkran deposit related to Cut 3 waste

removal and initial site establishment costs.

Costs

 AISC1 for Q2 2025 was $2,251/oz, compared to $1,759/oz in the comparative period. The increase in AlSC 1 was

primarily driven by higher capitalized stripping costs at the Abore and Esaase deposits and higher royalties

expense relative to Q2 2024. Also, during Q2 2024, low grade stockpiled ore was processed that had no

accounting book value and, as such, had no mining cost attributed to it, which resulted in lower operating costs

in the comparative quarter.

 Relative to Q1 2025, AISC 1 decreased by 10% in Q2 2025 due to 8% higher gold sales volumes.

 The Company expects AISC1 for FY 2025 at the higher end of its guidance range due to production expectations

at the lower end of the guidance range. In addition, there have been several factors outside of the Company’s

control that impact the Company’s reported AISC 1. Higher royalties resulting from higher realized gold prices

and the increase to the Growth and Sustainability Levy (“GSL”) from 1% to 3% effective April 1, 2025, are

estimated to impact FY 2025 AISC 1 by approximately a further $100/oz (at the current spot gold price).

Furthermore, the rapid appreciation of the Ghanaian Cedi against the US dollar during Q2 2025 adds further

upward pressure on AISC1, if sustained over the remainder of 2025.

Exploration

 Infill drilling completed at the Abore deposit led to discovery of a new high-grade zone immediately below the

mineral reserve pit shell at the south end of the Abore Main pit, including 50 meters (“m”) at 3.2 g/t gold ( refer

to news release dated May 5, 2025 ). The infill drilling also increased confidence in the mineral reserve and

mineral resource in the area in and around the known high-grade zone at the Abore South pit, while also

increasing the strike length of this zone from 90m to 180m.

 Positive results from a deep step-out drilling program at the Abore deposit, totaling 1,907m across a 1,200m

strike length, with mineralization intercepted in all four holes, including 36m at 2.5 g/t gold (refer to news release

dated July 14, 2025). The program confirmed the Abore granite and mineralizing system continues 200m below

the current Mineral Reserve pit shell over a strike length of at least 1,200m, remains open in all directions and

appears to carry sufficient grades and widths below the current Mineral Reserve pit shell to support the

potential development of bulk underground mining.

CONSOLIDATED FINANCIAL HIGHLIGHTS FOR THE THREE MONTHS ENDED JUNE 30, 2025 AND 2024

 The Company sold 29,287 ounces of gold in Q2 2025 at a quarterly record average realized gold price of

$3,317/oz for total revenue of $97.3 million. The increase in revenue from the comparative period was due to

a 45% increase in realized prices and a 5% increase in gold ounces sold.

 Income from mine operations for Q2 2025 totaled $37.2 million, compared to $23.6 million in Q2 2024. The

increase in income from mine operations was due to higher revenues as described above. This was partly offset

by higher depreciation expense on mining leases and higher depletion expense on Abore and Essase deferred

stripping costs during Q2 2025. Royalties expense was also higher in Q2 2025 due to higher earned revenues

and the increase to the GSL from 1% to 3% effective April 1, 2025.

 The Company reported net income attributable to common shareholders of $19.3 million in Q2 2025, compared

to $7.3 million in Q2 2024. The increase in net income during Q2 2025 was primarily due to the increase in

income from mine operations as described above, and partly offset by an increase in finance expense related to

realized and unrealized losses on the Company’s gold hedging derivatives.

 Reported Adjusted EBITDA 1 of $39.9 million in Q2 2025, compared to $16.2 million in Q2 2024. The increase in

Adjusted EBITDA1 was primarily driven by higher revenues, partly offset by higher royalties as described above.

 The Company generated $35.8 million of cash flow from operating activities in Q2 2025, compared to $4.5

million in Q2 2024. The increase in operating cash flow was primarily driven by higher realized gold prices during

Q2 2025.

 As of June 30, 2025, the Company had cash and cash equivalents of $114.7 million and no debt.

CONSOLIDATED FINANCIAL HIGHLIGHTS FOR THE SIX MONTHS ENDED JUNE 30, 2025 AND 2024

 The Company sold 56,281 ounces of gold during the six months ended June 30, 2025 at an average realized gold

price of $3,084/oz for total revenue of $173.9 million. The increase in revenue from the comparative period was

due to a 38% increase in realized prices and 32% increase in gold ounces sold.

 Income from mine operations for the six months ended June 30, 2025 totaled $52.5 million, compared to $29.8

million in the comparative period of 2024. The increase in income from mine operations was due to the increase

in revenue as described above and the Company only consolidating the financial results of the AGM from March

4, 2024 to June 30, 2024 in the comparative period. These factors were partly offset by higher depreciation and

depletion expense and royalties in 2025.

 The Company reported a net loss attributable to common shareholders of $7.5 million for the six months ended

June 30, 2025, compared to net income of $4.1 million in the comparative period of 2024. The decrease in net

income was primarily driven by higher realized and unrealized losses on gold hedging instruments in 2025. This

was partly offset by the Company consolidating a full six months of financial results of the AGM in 2025.

 Reported Adjusted EBITDA 1 of $58.9 million during the six months ended June 30, 2025, compared to $21.1

million in the comparative period of 2024. The increase in Adjusted EBITDA 1 was driven by higher realized gold

prices and the Company consolidating a full six months of financial results of the AGM in 2025.

 The Company generated $61.7 million of cash flow from operating activities during the six months ended June

30, 2025, compared to $17.5 million in the comparative period of 2024. The increase in cash flow from

operations was driven by higher realized gold prices and the Company consolidating a full six months of financial

results of the AGM in 2025.

This news release should be read in conjunction with Galiano’s Management’s Discussion and Analysis and the

Unaudited Condensed Consolidated Interim Financial Statements for the three and six months ended June 30,

2025 and 2024, which are available at www.galianogold.com and filed on SEDAR+.

1 Non-IFRS Performance Measures

The Company has included certain non-IFRS performance measures in this news release. These non-IFRS

performance measures do not have any standardized meaning and therefore may not be comparable to similar

measures presented by other issuers. Accordingly, these performance measures are intended to provide additional

information and should not be considered in isolation or as a substitute for measures of performance prepared in

accordance with IFRS. Refer to the Non-IFRS Measures section of Galiano’s Management’s Discussion and Analysis

for an explanation of these measures and reconciliations to the Company’s reported financial results in accordance

with IFRS.

 Total Cash Costs per Gold Ounce Sold

Management of the Company uses total cash costs per gold ounce sold to monitor the operating performance

of the AGM. Total cash costs include the cost of production, adjusted for by-product revenue and production

royalties per ounce of gold sold.

 AISC per Gold Ounce Sold

The Company has adopted the reporting of “AISC per gold ounce sold”. AISC include total cash costs, AGM general

and administrative expenses, sustaining capital expenditure, sustaining capitalized stripping costs, reclamation

cost accretion and lease payments made on the AGM’s mining and other service lease agreements per ounce of

gold sold.

 EBITDA and Adjusted EBITDA

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) provides an indication of the

Company’s continuing capacity to generate income from operations before taking into account the Company’s

financing decisions and costs of amortizing capital assets. Accordingly, EBITDA comprises net income (loss)

excluding finance expense, finance income, depreciation and depletion expense, and income taxes. Adjusted

EBITDA adjusts EBITDA to exclude non-recurring items and non-cash items (“Adjusted EBITDA”) and includes the

calculated Adjusted EBITDA of the AGM joint venture for periods prior to the consolidation of its ownership.

 Free cash flow

The Company believes that in addition to conventional measures prepared in accordance with IFRS, management

and certain investors and analysts use free cash flow to evaluate the Company’s performance with respect to its

operating cash flow capacity to meet non-discretionary outflows of cash. The presentation of free cash flow is

not meant to be a substitute for the cash flow information presented in accordance with IFRS, but rather should

be evaluated in conjunction with such IFRS measures. Free cash flow is calculated as cash flow from operating

activities, excluding one-time charges not indicative of current period cash flow performance, less cash flows

used in investing activities and payments made to mining and service contractors for leases capitalized under

IFRS 16.

 Adjusted net income (loss) and adjusted net income (loss) per common share

The Company has included the non-IFRS performance measures of adjusted net income (loss) and adjusted net

income (loss) per common share. Neither adjusted net income (loss) nor adjusted net income (loss) per share

have any standardized meaning and are therefore unlikely to be comparable to other measures presented by

other issuers. Adjusted net income (loss) excludes certain non-cash items or non-recurring items from net income

(loss) to provide a measure which helps the Company and investors to evaluate the results of the underlying core

operations of the Company and its ability to generate cash flows and is an important indicator of the strength of

the Company’s operations and performance of its core business.
