GHANA – The Prestea underground gold mine has reached commercial production says 90% owner and operator Golden Star Resources of Toronto. The government of Ghana holds a 10% interest. All construction is complete and output is expected to continue to ramp up during 2018.
Mining at Prestea also includes an open pit with a remaining life of less than one year.
The underground mine has an expected life of 5.5 years. Proven and probable reserves for the underground mine are 1.1 million tonnes averaging 13.93 g/t gold for 490,000 contained oz. of gold. The measured and indicated resource is 1.6 million tonnes at 15.69 g/t gold or 792,000 contained oz. Gold will be recovered using carbon-in-leach technology.
Guidance for the Prestea project in 2018 is 93,000 to 113,000 oz. of gold at a cash operating cost of US$740 to US$880 per ounce.
Golden Star has a program of exploration drilling underway at Prestea with the objective of boosting annual production and extending the mine life.
