GALIANO GOLD PROVIDES NKRAN DRILLING UPDATE

VANCOUVER, BC, Aug. 25, 2022 /PRNewswire/ - Galiano Gold Inc. ("Galiano" or the "Company") (TSX: GAU) (NYSE American: GAU) is pleased to provide an update of drilling results at Nkran following the completion of an infill drilling program at the Asanko Gold Mine ("AGM"), located in Ghana. The AGM is a 50:50 joint venture ("JV") with Gold Fields Ltd (JSE, NYSE: GFI), with the JV managed and operated by Galiano.

Effective February 28, 2022, Nkran has a Mineral Resource Estimate of 12.1 Mt at 2.09 g/t for 814 kozs indicated and 1.3 Mt at 2.23 g/t for 96 kozs inferred. The 2022 infill drilling program was designed to enhance confidence in the indicated Mineral Resource and explore for potential extensions of mineralization at Nkran.

Drilling has intercepted several high-grade intervals within and below the resource shell as described in National Instrument 43-101 Technical Report for the Asanko Gold Mine, Ashanti Region, Ghana, effective date February 28, 20221 and confirms continuity of mineralization within areas where higher levels of confidence were warranted. Results are currently being incorporated into an updated Mineral Resource Estimate which is expected to support an updated Mineral Reserve Estimate anticipated in Q1 2023.

Nkran Infill Drilling Highlights

24 diamond drill holes totalling 8,116m have been drilled at Nkran in 2022. Highlighted intercepts include:

• Hole NKDD22-100: 16 meters @ 47.3 g/t gold from 13.6m and 41 meters @ 3.0 g/t gold from 135.4m
• Hole NKDD22-099: 11 meters @ 27.6 g/t gold from 259m
• Hole NKDD22-083: 49 meters @ 3.4 g/t gold from 261.7m and 58.50 meters @ 3.5 g/t gold from 336m
• Hole NKDD22-086: 16 meters @ 5.4 g/t gold from 191m
• Hole NKDD22-080: 45 meters @ 2.3 g/t gold from 107m
• Hole NKDD22-105: 8 meters @ 10.4 g/t gold from 109m
• Hole NKDD22-106: 59 meters @ 2.7 g/t gold from 330m

Nkran Overview (See Table 1 for full drilling results)

The Nkran pit is located immediately adjacent to the 5.8 million tonne per annum processing plant, and has historically yielded the highest average mined grades on the Asankrangwa Belt and contributed significant cash flows to the AGM. During the mining of cut 2, Nkran produced 15.2M tonnes at 1.63 g/t and reported metallurgical recoveries of 94%.

"We are encouraged by these results which demonstrate the continuity of high-grade mineralization below the previously mined portions of the Nkran deposit," said Matt Badylak President and Chief Executive Officer. "This deposit has historically yielded significant cash flows due to its proximity to the processing plant, elevated grade profile and favourable metallurgy. It is important to note that mineralization extends below the current resource shell and remains open at depth. Going forward, we anticipate Nkran to be a key deposit in our upcoming Life of Mine Plan and are excited to incorporate these latest drilling results into an updated Technical Report scheduled for release in Q1 2023."

Nkran Geology and Cross Sections

The Nkran geological setting is typical of the Asankrangwa belt with a sedimentary sequence of interlayered shale, siltstone, and sandstone. Two granitic bodies intrude along shear zones that control mineralization which dips steeply to the northwest along with the sheared host stratigraphy.

Cautionary Note to US Investors Regarding Mineral Reporting Standards:
As a British Columbia corporation and a "reporting issuer" under Canadian securities laws, the Company is required to provide disclosure regarding its mineral properties, including the AGM, in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. In accordance with NI 43-101, the Company uses the terms mineral reserves and resources as they are defined in accordance with the CIM Definition Standards on mineral reserves and resources (the "CIM Definition Standards") adopted by the Canadian Institute of Mining, Metallurgy and Petroleum. In particular, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" used in this press release are Canadian mining terms defined in accordance with CIM Definition Standards. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

United States investors are also cautioned that while the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any "measured mineral resources", "indicated mineral resources", or "inferred mineral resources" that the Company reports are or will be economically or legally mineable.

Further, "inferred resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist. In accordance with Canadian rules, estimates of "inferred mineral resources" cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.

Neither Toronto Stock Exchange nor the Investment Industry Regulatory Organization of Canada accepts responsibility for the adequacy or accuracy of this release.
