(All dollar amounts are United States dollars unless otherwise stated)

VANCOUVER, BC, May 4, 2023 /PRNewswire/ - Galiano Gold Inc. ("Galiano" or the "Company") (TSX:GAU) (NYSE:GAU) reports first quarter ("Q1") operating and financial results for the Company and the Asanko Gold Mine ("AGM"), located in Ghana, West Africa. The AGM is a 50:50 joint venture ("JV") with Gold Fields Limited ("Gold Fields") ((JSE, NYSE:GFI) which is managed and operated by Galiano. All financial information contained in this news release is unaudited and reported in US$.

Asanko Gold Mine JV Key Metrics (100% basis):

• Safety: On February 6, 2023, the Company reported that two contractors had been fatally injured following an incident near the tailings storage facility ("TSF"). The Company has taken actions to further reinforce the Company's sustained commitment to Zero Harm and industry best practices in safety culture.
• Production performance: Gold production of 32,678 ounces during the first quarter, in line with 2023 production guidance of 100,000 to 120,000 ounces.
• Milling performance: Achieved milling throughput of 1.6 million tonnes ("Mt") of ore at a grade of 0.9 g/t during the quarter. Metallurgical recovery averaged 73% for the quarter, which was lower than prior periods due to processing lower grade stockpiles during Q1 2023.
• Cost performance and cash flow: Total cash costs¹ of $1,083/oz and AISC¹ of $1,268/oz for the three months ended March 31, 2023. Additionally, the JV generated positive cash flow from operations of $18.9 million and Free Cash Flow¹ of $12.0 million during the quarter.
• Revised AISC guidance: 2023 AISC¹ guidance for the AGM has been revised from between $1,900/oz to $1,975/oz to between $1,650/oz to $1,750/oz due to strong operational cost performance in Q1.
• Financial performance: Gold revenue of $65.1 million generated from 35,174 gold ounces sold at an average realized price of $1,850/oz for the quarter. Net income of $20.6 million during the quarter and Adjusted EBITDA¹ of $22.9 million.
• Exploration success: Advanced the first phase of an exploration drilling program at Nkran South Extension with the aim of increasing mineral reserves by converting inferred mineral resources to indicated mineral resources between the current Nkran Cut 3 reserve shell and the $1,800/oz resource shell, as well as to test for new mineralization along the southern margin of the deposit.
• Robust liquidity: $102.8 million in cash and cash equivalents, $7.0 million in gold sales receivables, $1.8 million in gold on hand and no debt as of March 31, 2023.

Galiano Gold Highlights:

• Improved long-term outlook at the AGM: The Company published the details of a new life-of-mine ("LOM") plan for the AGM on March 28, 2023 in a technical report titled "NI 43-101 Technical Report and Feasibility Study for Asanko Gold Mine, Ghana" with an effective date of December 31, 2022 ("2023 Technical Report"). The 2023 Technical Report was prepared independently by SRK Consulting (Canada) Inc. and includes the reinstatement of Mineral Reserves at the AGM. The new LOM plan identifies four main open-pit mining areas: Abore, Miradani North, Nkran and Esaase, and two satellite deposits: Dynamite Hill and Adubiaso.
• Stable balance sheet: Cash and cash equivalents of $56.2 million as at March 31, 2023, while remaining debt-free.
• Positive earnings: Net income of $8.5 million or $0.04 per common share during the quarter, which includes the Company's share of the JV's net earnings for the quarter.
• Generative exploration: During the quarter, the Company completed Phase 1 of its drilling program on its wholly owned Asumura property on the Sefwi gold belt in Ghana, designed to test for gold mineralization along two interpreted structural trends with coincident surface gold anomalies identified through soil sampling. A total of 95 holes were drilled for 12,467 metres in Phase 1, comprising 9,045 metres of reverse circulation drilling and 3,422 metres of diamond drilling.

"The first quarter marked multiple milestones for Galiano," stated Matt Badylak, Galiano's President and Chief Executive Officer, "We reinstated Mineral Reserves with the updated 2023 AGM Technical Report, demonstrating an improved eight-year mine life, with annual production averaging 217,000 ounces of gold per year at all-in sustaining costs of $1,143 per ounce. Significant optimization opportunities have been identified and an aggressive exploration program is underway on the large, highly prospective land package. During the quarter, we continued to generate significant cash flows through stockpile processing, further strengthening the AGM's balance sheet to move forward with the revised life of mine plan. At the corporate level, we closed the quarter with over $56 million in cash, no debt, and remain in an enviable position to further grow the Company.

Looking ahead, we have improved 2023 cost guidance, reducing all-in sustaining costs from over $1,900 per ounce to between $1,650 to $1,750 per ounce. We continue to focus on the plan to re-commence hard rock mining during the fourth quarter of 2023, while working to strengthen safety awareness across site to achieve our goal of Zero Harm at the Asanko Gold Mine."

Asanko Gold Mine – Summary of quarterly operational and financial highlights (100% basis)

Asanko Gold Mine – Financial and operational highlights for the three months ended March 31, 2023 and 2022 (100% basis)

• The AGM produced 32,678 ounces of gold during Q1 2023, as the processing plant achieved milling throughput of 1.6 Mt of ore at a grade of 0.9 g/t with metallurgical recovery averaging 73%. Recovery was lower than prior periods due mainly to processing of lower grade stockpiles and was in line with expectations.
• Sold 35,174 ounces of gold in Q1 2023 at an average realized gold price of $1,850/oz for total revenue of $65.2 million (including $0.1 million of by-product silver revenue), a decrease of $12.3 million from Q1 2022. The decrease in revenue quarter-on-quarter was primarily a function of a 16% reduction in sales volumes relative to Q1 2022.
• Total cost of sales (including depreciation and depletion and royalties) amounted to $40.5 million in Q1 2023, a decrease of $26.4 million from Q1 2022. The decrease in cost of sales was primarily due to 16% fewer gold ounces sold, lower mining contractor costs and processing ore that had no carrying value for accounting purposes. Labour costs were also lower in Q1 2023 resulting from the restructuring of the AGM's workforce completed at the end of Q1 2022 ($4.5 million decrease). These factors were partly offset by inflationary pressures on key reagents and other consumables. Depreciation and depletion expense was also $7.6 million lower in Q1 2023 relative to Q1 2022, due mainly to fewer gold ounces sold, lower depreciation on mining related assets resulting from the temporary cessation of mining at the end of Q2 2022, processing existing stockpiles that had no carrying value for accounting purposes, and lower depreciation on capitalized leases. These factors were partly offset by the impact on depreciation caused by the $63.2 million impairment reversal on MPP&E recorded at December 31, 2022.
• Income from mine operations for Q1 2023 totaled $24.7 million compared to income from mine operations of $10.6 million in Q1 2022. The increase in income from mine operations was due to a $26.4 million decrease in cost of sales, partly offset by a $12.3 million decrease in revenue (as described above).
• Reported Adjusted EBITDA¹ of $22.9 million in Q1 2023 compared to $13.1 million in Q1 2022.
• Total cash costs¹ were $1,083/oz in Q1 2023 compared to $1,361/oz in Q1 2022, a 20% decrease. Although gold sales volumes decreased by 16% in Q1 2023, total cash costs per ounce¹ were lower compared to Q1 2022 as a result of lower mining contractor costs and the processing of ore that had no carrying value for accounting purposes. In addition, labour costs were lower in Q1 2023 ($4.5 million decrease) as a result of the AGM's workforce restructuring completed at the end of Q1 2022. These factors were partly offset by inflationary pressures on key reagents and other consumables.
• AISC¹ for Q1 2023 was $1,268/oz compared to $1,559/oz in the comparative period. AISC¹ was lower in the current quarter predominately due to the decrease in total cash costs per ounce¹ mentioned above and lower sustaining lease payments ($105/oz decrease) related to the temporary cessation of mining since the end of Q2 2022. This was partly offset by an increase in sustaining capital expenditures ($92/oz increase) relating to a TSF lift.
• The AGM generated $18.9 million of cash flows from operating activities and free cash flow¹ of $12.0 million during Q1 2023. This compares to $3.9 million of cash flows from operating activities and negative $3.4 million of free cash flow¹ during Q1 2022. The increase in free cash flow¹ was primarily due to higher AISC margins¹.

Galiano Gold Inc. – Financial highlights for the three months ended March 31, 2023 and 2022

• The Company reported net income of $8.5 million in Q1 2023, compared to a net loss of $1.5 million in Q1 2022. The increase in earnings during Q1 2023 was due to the recognition of the Company's share of the JV's net earnings for the quarter and a $2.3 million positive fair value adjustment on the Company's preference shares in the JV. During Q1 2022, the Company did not recognize its share of the JV's net loss as the carrying value of the Company's investment in the JV was nil as at March 31, 2022.
• Adjusted EBITDA¹ for Q1 2023 amounted to $6.7 million, compared to a loss of $1.5 million in Q1 2022. The increase in Adjusted EBITDA¹ was primarily a result of the Company's share of the JV's Adjusted EBITDA. During Q1 2022, the Company did not recognize its share of the JV's net earnings as the recoverable amount of the Company's equity investment was estimated to be nil.
• Cash used in operating activities in Q1 2023 was $0.5 million, compared to $3.2 million in Q1 2022. The reduction in cash used in operating activities from Q1 2022 to Q1 2023 was driven by working capital movements, specifically related to the Company's service fee receivable from the JV.
• As of March 31, 2023, the Company had cash and cash equivalents of $56.2 million, while remaining debt-free.

2023 AGM Outlook

The Company provided preliminary guidance for 2023 based on the new LOM plan for the AGM, which outlined production of between 100,000 to 120,000 ounces at AISC¹ between $1,900/oz and $1,975/oz. Given the strong performance in Q1 2023, the AISC¹ is now expected to be between $1,650/oz to $1,750/oz. AISC¹ is still anticipated to be elevated in 2023 compared to the LOM average primarily due to waste stripping necessary to restart mining at Abore, which will benefit future years production, as well as higher expenditures on the TSF.

The Company is not adjusting capital guidance, and it continues to work on obtaining the necessary joint venture approvals and develop a detailed mining restart plan that may impact the timing of capital expenditures in 2023. It is currently expected that $38 million of sustaining capital expenditures, excluding capitalized waste stripping, will be spent on the TSF Stage 7 expansion, plant infrastructure and water management in 2023 (spend as of March 31, 2023: $4.9 million). Additionally, development capital of $24 million is expected to be spent on Abore and Miradani North site establishments (spend as of March 31, 2023: $0.9 million).

For 2023, the exploration budget at the AGM is estimated at $15 million (spend as of March 31, 2023: $3.5 million), which includes approximately 40,000 metres of drilling, as well as ground geophysics, trenching, soil sampling and regional mapping. The 2023 exploration program is focused on targeting discoveries on underexplored greenfield areas of the AGM tenements, as well as increasing the Mineral Reserve and Mineral Resources at known deposits.

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 and the JV's reported financial results in accordance with IFRS.

• Total Cash Costs per ounce
  
  Management of the Company uses total cash costs per gold ounce sold to monitor the operating performance of the JV. Total cash costs include the cost of production, adjusted for share-based compensation expense, by-product revenue and production royalties of 5% per ounce of gold sold.
• All-in Sustaining Costs Per Gold Ounce and All-in Sustaining Margin
  
  The Company has adopted the reporting of "all-in sustaining costs per gold ounce" ("AISC") as per the World Gold Council's guidance. AISC include total cash costs, corporate overhead expenses, sustaining capital expenditure, sustaining capitalized stripping costs, reclamation cost accretion and lease payments made to and interest expense on the AGM's mining and service lease agreements per ounce of gold sold. Excluded from AISC are one-time severance charges in line with World Gold Council guidance. All-in sustaining margin is calculated by taking the average realized gold price for a period less that period's AISC.
• EBITDA and Adjusted EBITDA
  
  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 interest expense, interest income, amortization and depletion, and income taxes. Adjusted EBITDA adjusts EBITDA to exclude non-recurring items and to include the Company's interest in the Adjusted EBITDA of the JV. Other companies and JV partners may calculate EBITDA and Adjusted EBITDA differently.
• Free cash flow
  
  The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use free cash flow to evaluate the JV'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 flows from operating activities of the JV adjusted for cash flows associated with sustaining and non-sustaining capital expenditures 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 or net loss to provide a measure which helps the Company and investors to evaluate the results of the underlying core operations of the Company or the JV and its ability to generate cash flows and is an important indicator of the strength of the Company's or the JV's operations and performance of its core business.
