Production
Located in Ghana, West Africa, the Asanko Gold Mine is Galiano’s flagship asset since 2016. A parity join venture with Gold Fields, it is managed and operated by Galiano, with a 10% interest held by the Government of Ghana.
The Asanko Gold Mine is a multi-deposit complex, with four main open-pit mining areas: Abore, Miradani North, Nkran and Esaase, and multiple satellite deposits, situated on the Asankrangwa Gold Belt, and a 5Mtpa carbon-in-leach (CIL) processing plant. Gold production commenced in January 2016 and commercial production was declared on April 1, 2016.
In 2022, the mine produced 170,342 ounces, primarily from stockpiles, achieving the upper end of revised guidance of 160,000 to 170,000 ounces. The Asanko Gold Mine is expected to produce between 100,000 to 120,000 ounces from stockpiled material in 2023, at all-in sustaining cost guidance of between $1,900/oz to $1,975/oz. All-in sustaining cost is anticipated to be elevated in 2023, primarily due to waste stripping necessary to restart mining at Abore, which will benefit future years production, as well as higher expenditures on the tailings storage facility.
Approximately 2,200 people are employed at the mine. 99% of the total workforce are Ghanaians, of which around 53% are from our local communities.
The Asanko Gold Mine has a downstream tailing storage facility, further details are available here: Asanko TSF Disclosure
Geology
The Nkran deposit is located within the Kumasi Basin on the "Asankrangwa gold belt". The basin is bound to the south by the Ashanti Fault/Shear and the Bibiani shear to the north. The Asankrangwa gold belt expresses itself as a complex of northeast trending shear zones situated along the central axis of the Kumasi Basin. The Nkran deposit is located on a jog along the regional Nkran Shear, which is a zone of about 15 km in width and may be traced on a northeast to southwest trend for a distance of some 150 km. This is one of several major northeast trending shears/structures that bisect the Kumasi Basin/Asankrangwa Gold Belt.
