With cessation of mining at Esaase in May 2022 and in-situ Mineral Reserve depletion at Akwasiso in July 2022, since August 2022 Asanko has been treating stockpiles until prefeasibility work supporting a viable LOM plan has been completed.
There are several mineral deposits at the AGM that are in different stages of exploration and advancement. Six deposits are viable to be mined by conventional truck and shovel open pit mining techniques; they are: Nkran, Esaase, Miradani North, Abore, Dynamite Hill and Adubiaso.
All pits will utilize truck-loader mining methods operated by contractors as has traditionally been the case at the AGM. Ore and waste material will be drill and blasted as required in 6 m benches, loaded using front-end loaders or backhoe excavators and then hauled using a mix of articulated and rigid body trucks. Mining will be operated by experienced contractors using either 40-t CAT 740 and/or 91-t CAT 777 trucks, depending on pit size and equipment availability.
All six pits in this report were previously subject to mining activities. The last mining activity at the AGM was in the Esaase pit, terminated in May 2022, followed by the Akwasiso pit, terminated in July 2022; however, the mill continues operations using stockpiled ore.
There are ROM stockpiles near each pit and ROM stockpiles near the primary crusher adjacent to the processing plant. Ore from Esaase, Abore, Miradani North and Dynamite Hill will be stockpile ........
