The Syama Gold Mine is a large-scale operation, comprising the established Syama Underground Mine, the Tabakoroni Complex and the recently discovered Syama North 3Moz resource, along with several satellite oxide pits.
The Resolute is working through a PFS for low capital expansion options to further expand the Syama North Sulphide operations, with the results expected in 2023.
The March 2022 LOM Plan assumed first production from Tabakoroni underground in 2026. Following the discovery of the Syama North resource, the Resolute has deferred the development of the Tabakoroni Sulphide Project. |

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 ........

Syama Gold Mine
The 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 by backfillin ........
