The Syama Gold Mine, located in the south of Mali, West Africa approximately 30km from the Côte d’Ivoire border and 300km southeast of the capital Bamako, comprises the Syama Underground Mine and the Tabakoroni Open Pit Mine.
The Syama Underground Mine is owned by Société des Mines de Syama S.A. (SOMISY). Resolute’s asset ownership of Syama is an 80% interest in SOMISY and the Government of Mali has a 20% interest in SOMISY. Tabakoroni is owned by Société des Mines de Finkolo SA (SOMIFI) of which Resolute owns 90% through its wholly owned subsidiary, Resolute (Finkolo) Pty Ltd. The Government of Mali owns a 10% free carried interest in SOMIFI.
Syama is a large-scale operation which comprises two separate processing plants: a 2.4Mtpa sulphide processing circuit and a 1.5Mtpa oxide processing circuit. The sulphide circuit comprises three-stage crushing, milling, flotation, roasting, calcine leaching and elution with ore sourced from the Syama Underground Mine and stockpiles. The oxide circuit comprises conventional crushing, SAG milling and leaching, with ore sourced from the Tabakoroni Open Pit Mine.
Tabakoroni is located 35km south of the Syama processing plant. Mining commenced during the September 2018 Quarter with first ore through the mill in November 2018. The culmination of successful exploration and the completion a Pre-Feasibility Study has led to the declaration of a maiden underground Ore Reserve at Tabakoroni of 2.9 million tonnes at 4.6 grams per tonne gold for 430,000oz. Continued exploration success and resource conversion drilling are expected to increase this Ore Reserve during 2021.
Syama sulphide production is forecast to increase by more than 25% to between 155,000oz and 170,000oz with a resulting decrease in AISC to between US$1,200/oz and US$1,275/oz.
Syama oxide production of 80,000oz to 85,000oz is forecast at an AISC between US$1,050/oz and US$1,090/oz from the Cashew and Tabakoroni satellite operations.
Syama Solar Hybrid Power Station
In 2019, Resolute partnered with Aggreko plc for the development of a new solar hybrid power station at Syama. This innovative power solution will combine battery, thermal and solar generation technologies to deliver cost effective and environmentally friendly power. Once fully operational, the new power station is expected to generate long term electricity cost savings of up to 40% and reduce carbon emissions by approximately 20%.
The new power plant will be delivered in two stages. The first phase will comprise the installation of three new thermal energy Modular Block generators and a battery storage system. The second phase will see the construction of a 20MW solar array on the surface of the existing Syama Tailings Storage Facility, thereby maximising positive environmental outcomes and augmenting Resolute’s rehabilitation program.
In addition, as a joint corporate social responsibility initiative, Resolute and Aggreko have agreed to jointly fund community power investments in the Syama region. The aim of these investments will be to provide sustainable power to local villages in the Syama region which currently have limited access to reliable electricity.
