Portugal-based contract mining firm Mota-Engil says its Africa subsidiary has signed a mining contract for the Lafigué project in Côte d’Ivoire worth some $600 million.
Lafigué is in the north-central part of the country, some 500 km from Abidjan, within the northern end of the Oumé-Fetekro greenstone belt.
Endeavour launched construction ofn its 80%-owned project in October, following completion of a definitive feasibility study that outlined a project able to produce approximately 200,000 oz/y at an all-in sustaining cost of $871/oz over its initial 12.8-year mine life. This featured a six-stage open-pit mine amenable to conventional open-pit, drill and blast mining.
Mining is due to occur in 10-m benches, with double batters to achieve the final 20-m bench heights. Ore mining will occur in three to four flitches, selectively using smaller loading equipment in order to decrease dilution. The study detailed that diesel excavators and trucks will be used for loading and haulage, with a fleet comprising 400-t-class face shovels to load 180-t capacity dump trucks for waste mining, and 200-t-class excavators to load 180-t capacity dump trucks for ore mining.
First gold production is expected early in the September quarter of 2024.
The mining services to be carried out by Mota-Engil under the contract includes mine development, pit dewatering, free digging, drilling, blasting, loading and hauling of ore and waste, it says.
The works are scheduled to start in December 2023 and will have a duration of 60 months.
