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 lodes can be identified. Two highly graphitic fault zones, historically referred to as pug seams or fissures, are associated with the major shear zone on footwall and hanging wall sides.

In general, the orebody dips east at 60 - 80°, crossing the regional structure at acute angles. At the centre of the mine the orebody alignment is 030 - 035° which changes to around 020° at the northern end of the mine. The strike of the bedding cuts across the strike of the ore body at acute angles. Traditionally the ore body has been divided into a northern and southern part based on the location of the central shaft, which lies on section line 5400N. Despite this the orebody is essentially continuous.

The southern ore zone is around 180m long and consists of a composite vein of qu ........

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 haulage roads, safety berms, waste dumps and mining benches are advanced. First ore has been delivered to the Run of Mine Pad, more than one month ahead of schedule. The Bibiani Mine plans to pour its first gold in Q3 2022.

First gold poured July 7, 2022. Gold dore’ shipped late July.

• Bibiani will produce 175,000 oz in its first 12 months of operation, 230-280 Koz/ year through 2030.

• 4 stage development of the Main Pit to support mining to +/- 350m depth and +8 years operation. This will access the approximate 2.3 Moz open pit resource.

• The Mining Contractor has been mobilized to deliver +3 Mt/y ore to the process plant, from the open pit mines.
• Exploration continues, with a view to developing satellite deposits & extending open pit mining to +10 years.

Underground mine planning has been initiated, to add 90Koz/y from 2026 and increase LOM to +14years.

Mining will be undertaken by long hole open stoping (LHOS) mining methods. A trade-off study of various LHOS methods was undertaken and the selected mining methods were:

• The main mining method will be LHOS with pillars. This method was applied to the majority of the mining areas, where the stope blocks are less continuous, occur in mu ........
