The gold deposits at Bibiani are structurally controlled mesothermal lode-type deposits. The mineralization is associated with quartz veins and quartz stockworks which are hosted within a sequence of Lower Birimian fine to medium grained turbiditic sandstones. The sedimentary turbidite sequence is tightly folded, with west-dipping axial planes and localised development of steep west-northwest dipping shear zones which have acted as conduits for the initial gold mineralization. Gold is closely associated with arsenopyrite and pyrite. Sericite alteration is also commonly observed, both along mineralized structures, and associated with the felsic intrusives. High-grade veins often occur within graphitic shales which generally contain significant sedimentary/metamorphic pyrite.

The Bibiani deposit is hosted within a thick sequence of fine-grained graded turbidites with localised thin interbeds of fine to medium- grained turbiditic sandstones. The orebody is a mesothermal lode type deposit which is similar to the lode deposits in the Konongo Axim belt hosting the significant Obuasi deposit. The Bibiani orebody geometry is structurally controlled by a steep, north to north-east trending shear corridor 200 - 400m wide, within Lower Birimian sediments and close to the \ eastern contact of the Upper Birimian. The shear zone includes quartz infill as massive veins and quartz stock works. In the widest parts of the orebody, two and locally three individual quartz reefs or lod ........

Mining at Bibiani will be by conventional open pit mining methods involving drilling, blasting, loading and hauling with diesel driven equipment. Bench heights for drilling and blasting will be 6.0m. Loading of the blasted mineralised material and waste will take place in two by three metre flitches on each bench.

The open pit mining operation will be undertaken by a mining contractor, who has been engaged and has commenced mining operations.

The Bibiani mining operation is planned to sustain a steady state production rate of 4.0Mtpa. The current LoM plan includes mining from three pits; the Main pit and two satellite pits; namely Walsh and Straus Pits.

The mining strategy that will be followed at Bibiani is to commence pre-stripping at the Bibiani Main Pit and Walsh simultaneously. This work started in March 2022. Mineralised material will be produced from the Satellite Pits (Walsh and Strauss) while waste stripping continues in the Bibiani Main Pit and production from the Bibiani Main Pit is built up. In the early years of operation production will be from a combination of the Satellite Pits and the Bibiani Main Pit. Once the Satellite Pits are mined out the full production rate will be produced from the Bibiani Main Pit.

On February 28, 2022, Open Pit Mining Operations have started, with focus on delivery of ore from the Strauss and Walsh satellite pits. The #1 Cutback at the Main Pit has also started. Refurbishment of mine haula ........
