Edikan Mine

90% owned by Perseus

The Edikan Gold Mine is a large-scale, low-grade multi open-pit operation located on the Asankrangwa Gold Belt, Ghana.

Perseus commenced commercial production at Edikan in 2012, and the mine has since produced more than 1.8 million ounces of gold.

At 30 June 2021, remaining Reserves at Edikan totalled 1.32 million ounces of gold at an average grade of 1.10g/t gold.

Edikan was Perseus’ first mining operation commencing commercial production in January 2012. The mine is in the Central Region of Ghana, within the Ashanti Gold Belt. Gold ore is sourced from several open pits and processed through a centralised processing facility with capacity to process up to 8 million tonnes of ore per annum. From 1 July 2020, gold production will average 212,000 ounces per annum for the remaining currently known 7 years of mine life, including average gold production of approximately 231,000 ounces per annum over the next four years. AISCs are expected to be in the range of US$870-US$890 per ounce over the remaining life of mine.

In 2019, Perseus signed an agreement with local Ghanaian company, Adio-Mabas Ghana Ltd, to acquire the 23.85sq km Agyakusu Prospecting License, that adjoins Perseus’s Edikan mining leases, and is located between 2km and 8km from the Edikan processing facility. Exploration success at Agyakusu could potentially extend Edikan’s mine life.

Geology

The area of the Edikan Gold Mine is underlain principally by Paleoproterozoic Birimian flysch-type metasediments consisting of dacitic volcan-iclastics, greywackes plus argillaceous (phyllitic) sediments, intensely folded, faulted and metamorphosed to upper greenschist facies. Numerous small “Basin-type” or “Cape Coast-type” granite bodies have intruded the sediments along several regional structures.

Gold mineralisation at Edikan occurs principally in the granite bodies, but also in classic “Ashanti-style” sediment hosted shear zones. The granite hosted gold mineralisation is free milling and occurs in two to three generations of abundant, narrow quartz veining associated with up to 3% pyrite, lesser arsenopyrite and traces of sphalerite, chalcopyrite, galena and rutile.

Gold occurs as very fine grains, often along sulphide grain boundaries and in fractures in sulphides, usually at or near vein margins. Coarse visible gold is occasionally observed within the quartz.

Edikan Production Process

Workforce and Community

At Edikan, we have a workforce of over 2,500 employees and contractors. Over 98% of our employees are Ghanaian nationals, and 44% of the workforce that is drawn from the local communities. Mining has been undertaken on an industrial scale for many years in Ghana resulting in a knowledgeable and highly skilled Ghanaian population.

Perseus established the Edikan Trust Fund in 2012 and contributes US$300,000 annually for community development. The Fund is administered by a committee made up of community members, traditional authorities, and Perseus representatives. The Edikan Fund provides funds for critical community initiatives including infrastructure projects and implementing health, education, and livelihood development programs. Perseus also independently funds a range of education, health, and social wellbeing program within the five villages located adjacent to the mine.
