Modern Mining June 2019

REGIONAL FOCUS: WEST AFRICA

138,6 Mt at 1,13 g/t Au (at a 0,5 g/t Au cut-off) compared to 4,8 Moz previously. It is envisaged that mining of the Namdini project will include drill and blast as well as conventional load and haul operations using 400-tonne class excavators in a face shovel con- figuration and 130-tonne class rigid body dump trucks hauling on designed access roads. An auxiliary mining fleet of dozers, graders, water carts and utility vehicles will support the min- ing operation. Mining is proposed on 3 to 4 m flitches in the ore, within 10 m benches. There is expected to be a limited amount of free-dig material with the majority of material assumed to require drilling and blasting. Mining will be carried out using staged cut- backs with four identified stages incorporated within the LoM final pit including an initial stage (Starter Pit) which will facilitate early access to the higher-grade ore near the surface. Cardinal was originally intending to deliver the Feasibility Study (FS) on Namdini in the current (June) quarter but has now reverted to the original Q3-2019 FS publication timeline so that final testwork results from the Aachen™ process can be incorporated. 

The Namdini project is located in north-eastern Ghana close to the border with Burkina Faso.
