Galiano Gold Intersects High-grade Mineralization Below Existing Resource At Nkran

VANCOUVER, Sept. 8, 2022 - Galiano Gold Inc. ("Galiano" or the "Company") (TSX: GAU) (NYSE: GAU) is pleased to provide initial positive drilling results testing the extension of mineralization at Nkran for underground mining potential at the Asanko Gold Mine ("AGM"), in which all eight drilled holes intercepted mineralization.

The program consisted of two widely spaced (160m) pilot holes yielding eight directional (daughter) diamond holes for a total of 5488m. Drilling intersected high-grade mineralization including 14 meters @ 4.56 g/t gold in hole NKDD22-090W1 and 7 meters @ 7.03 g/t gold in hole NKDD22-090W2 along a strike length of 160m at depths between 230m and 630m below the resource shell as described in the NI 43-101 Technical Report for the AGM filed on SEDAR. Mineralization remains open in all directions, including the zone above this mineralization and below the bottom extents of previous infill resource drilling (see news release Galiano Gold provides Nkran drilling update dated August 25, 2022). Several mineralized intercepts indicate grades and widths that may be amenable to underground mining and additional drilling is currently being contemplated to follow-up on these initial results.

"It is encouraging to have intercepted mineralization with these grades and at depths well below the existing Mineral Resource at Nkran," said Matt Badylak, President and Chief Executive Officer. "These results are the beginning of our work to understand the underground mining potential below the known Cut 3 Resource. The outcomes of this program are not only encouraging for Nkran but may also form an initial proof of concept for underground mining potential on the Asankrangwa Gold Belt."

Nkran Deeps Phase 1 Highlights

• Hole NKDD22-090W1: 14 meters @ 4.56 g/t gold from 518.6m including 4 meters @ 9.48 g/t gold from 528.8m, 4 meters @ 4.77 g/t gold from 581m and 2 meters @ 37.57 g/t gold from 625m
  
  
• Hole NKDD22-090W2: 7 meters @ 7.03 g/t gold from 379m, 5 meters @ 4.18 g/t gold from 431m and 6 meters @ 7.25 g/t gold from 480m
  
  
• Hole NKDD22-090W3: 6 meters @ 6.99 g/t gold from 474m
  
  
• Hole NKDD22-090W4: 8 meters @ 5.19 g/t gold from 298m
  
  
• Hole NKDD22-077W1: 4.5 meters @ 7.28 g/t gold from 376.3m
  
  
• Hole NKDD22-077W2: 6 metres @ 7.25 g/t gold from 480m

Intervals indicated are not true widths as there is insufficient information to calculate true widths. However, drill holes have been drilled to cross interpreted mineralized zones as close to perpendicular as possible.

The Nkran geological setting is typical of the Asankrangwa gold 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.

Figure 1 shows the location of drill holes and intercepts in plan view. Cross sections (Figures 2, and 3) as well as a long section (Figure 4) demonstrate the extent of observed Nkran Deeps mineralization at depth and along strike.

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 the Toronto Stock Exchange nor the Investment Industry Regulatory Organization of Canada accepts responsibility for the adequacy or accuracy of this release.
