Mine Life2033
Syama Gold Mine is a large-scale operation, comprising the established Syama Underground Mine, the Tabakoroni Complex comprising an open pit, and recently discovered underground Ore Reserve, along with several satellite oxide pits.

Mining and processing are via the Syama Underground sulphide mine and 2.4Mtpa processing plant while oxide ore is mined from the Tabakoroni complex together with multiple satellite pits and processed through a 1.5Mtpa capacity plant.

Summary:

The Syama Project is found on the northern margin of the Achaean-Proterozoic Leo Shield which forms the southern half of the West African Craton. The project area straddles the boundary between the Kadiana–Madinani terrane and the Kadiolo terrane. The Kadiana-Madinani terrane is dominated by greywackes and a narrow belt of interbedded basalt and argillite. The Kadiolo terrane comprises polymictic conglomerate and sandstone that were sourced from the Kadiana-Madinani terrane and deposited in a late- to syntectonic basin. Prospects are centred on the NNE striking, west dipping, Syama-Bananso Fault Zone and Birimian volcano-sedimentary units of the Syama Formation. The major commodity being sought is gold. The Tabakoroni deposit is hosted in upright tightly folded greenstone rocks of the Syama Formation, comprising interbedded basalt and sediment units, and an overlying complex sequence of deep marine and turbiditic sediments. The sequence overlying the basalts contains interbedded carbonaceous units (silts and shales) that are preferentially deformed, and which form the Tabakoroni Main Shear Zone (TMSZ) that lies along the approximate contact of the greenstone-sediment sequence. Gold mineralisation occurs within the TMSZ associated with quartz vein stockworks and stylolitic quartz reefs. The Tabakoroni Porphyry Zone is located on a NNE trending splay of the NNW oriented Main Tabakoroni Shear Zone. Host rocks are comprised of interbedded greywacke and shale with small intrusi ........

Summary:

Syama is a large-scale operation which comprises two separate processing plants: a 2.4Mtpa sulphide processing circuit (ore sourced from the Syama Underground Mine) and a 1.5Mtpa oxide processing circuit (ore sourced from the Tabakoroni Open Pit Mine and near-mine oxide deposits). Syama Gold Mine The current mining method for underground exploitation is Sub-level caving. Tabakoroni A Pre-Feasibility study determined the Tabakoroni mining method would be by long hole open stoping. No Mineral Resource margin A Pre-Feasibility study determined the mining method would be by long hole open stoping. No Mineral Resource margin (external) dilution has been modelled. A minimum stope dip of 30 degrees on the footwall was applied. More rigorous mining assumptions and parameters will be applied during the conversion to Ore Reserves. A Pre-Feasibility Study was completed on Tabakoroni Underground in late 2020. Tabakoroni open pit has been in continuous mining operation since August 2018. During this time the performance of the open pit has shown a positive reconciliation between mineral resources and gold production and delivered positive cashflows. Data from the current open pit operations which also applies to the intended underground operation, such as existing infrastructure and ore haulage cost, were used as part of the underground study. Long hole open stoping is considered the most suitable mining method to extract the underground deposit. Long term support will be providing b ........

Water Supply

At Syama, water is extracted from the Bagoe River, where permitted extraction rates decrease in the dry season and no water abstraction is permitted in April each year. This is supplemented by a significant volume of accumulated rainfall that is stored in the Northern Satellite pits, along with storm and groundwater inflows into the underground mine. In addition, process water is obtained from the TSF decant water.
