Deposit Type

  • Orogenic


Summary:

The Fekola deposit is an example of a disseminated orogenic gold deposit.

The Fekola Mine is hosted within an inlier of Birimian rocks of the West African craton, termed the Kédougou–Kéniéba Inlier (KKI), located on the border of eastern Senegal, western Mali and northern Guinea. The KKI is a greenstone belt characterized by sequences of approximately north–south-trending volcanic and sedimentary rocks, intruded at various stages by gabbroic suites and calc-alkaline granitoids. The major greenstone units include the Mako, Dialé–Daléma, Falémé and Kofi Series rocks. Two main crustal-scale structures; the Main Transcurrent Zone (MTZ) in the west and the Senegal-Malia shear zone system (SMSZ) in the east, bisect the KKI. The Kofi Series hosts significant gold mineralization on the eastern side of the Senegal–Mali Shear Zone and is the primary host to mineralization in the Project area.

The Fekola deposit, including the Fekola North Extension has been outlined along strike for 3,280 m, can be as much as 200 m in width and extends based on current drilling to at least 440 m depth. Gold mineralization at Fekola is dominantly hosted within bedrock and occurs with fine-grained disseminated pyrite, commonly in association with high strain zones and fold hinges. High-grade mineralization is concentrated in a high-grade shoot (>2 g/t Au) that plunges shallowly to the north–northwest at 14°.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mining operations use conventional open pit mining methods and equipment, using Owner-operator mining equipment and labour. Mining is based on a phased approach with stockpiling to bring high-grade forward and provide operational flexibility.

The proposed mine production schedule involves the movement of a total 74.4 Mt/a of mineralized material and waste to sustain processing of 7.5 Mt/a of high-grade mineralized material while stockpiling as much as 9.3 Mt of low-grade mineralization and 9.6 Mt of currently sub-economic mineralization.

The mine design is based on cutback widths of 200–250 m, minimum mining width of 40m on all benches except floor of ultimate pit with 25m, nominal road and ramp widths of 27 m and a ramp gradient of up to 10%.

Waste storage facility design is based on 10 m vertical lifts with 18º faces and 5 m berms, with facility location considerations based on minimising haulage, surface water drainage and area availability.
