SnapshotKouroussa achieved its first gold pour ahead of schedule in June 2023. Despite challenges faced since then, operations have been steadily progressing with commercial production set to take place in H2-2024. Currently, the mine is navigating through operational disruptions due to contractual disputes with Corica Mining Services (“Corica”), the principal contract miner, with minimal disruption on the ground and the appointment of a mining contractor, ETASI. However, proactive steps have been taken to address these challenges to resume operations and ramp-up to commercial production. In May 2024, the Company announced that it had agreed with Corica to remobilise equipment to site and recommence the ramp-up in operations towards commercial production.

Summary:

The Republic of Guinea is located in the southern part of the West African craton. Guinea has a rich and varied mining potential with reserves estimated of several billion tonnes of bauxite and iron ore, plus gold, diamonds, and base metals. The gold ore occurs as secondary (alluvium beds and terraces of rivers) or primary (veins, quartz veins) deposits. The major gold deposits are located in the Birimian Domain in Upper Guinea, and current annual production is about 8 to 10 tons of gold, divided between small-scale miners and industrial companies. The four main known gold metallogenic areas of Guinea include (i) the Siguiri Basin of Upper Guinea (Kankan, Siguiri, Kouroussa, Mandiana) and Dinguiraye; there are lateritic and/or saprolitic deposits or indications of gold-bearing quartz veins and stockworks; (ii) the Siguiri Basin of savanna Guinea (Kankan, Siguiri, Kouroussa, Mandiana); (iii) the Kouroufing (Mamou and Kerouané) and Beyla areas located in the southeast also have auriferous quartz veins; and (iv) primary deposits of N’Zérékoré sheet NZE-Q2 (Au), coordinates 8° 12’ to 8° 08’ W longitude and 7° 40’ N latitude (Kogota-Guipo), hosted in amphibolite gneisses; Au and Ag of 1.25 to 2.1 g/t and 3.45 to 41.3 g/t, respectively. The primary deposit NZE-zone Q3 (Au) has coordinates 8° 26’59’’ longitude W and 7° 37’30’’ latitude N; the orebody is characterized by tuffites with hematite. These lithologies are located in Lower Proterozoic and Archean domains. In these areas, there are faults observed and/or interpreted, as well as kimberlite veins and pipes. The genesis of these gold deposits remains poorly understood compared to others in the West African region. Future research work on these deposits should be oriented on the model, type, and genesis (tectonic setting, host environment, texture and mineralogy of ore, age of host rocks and ore, source and composition of ore-forming fluids, hydrothermal alteration and zoning, structural setting, etc.) to assist their interpretation. The regional geology and metallogeny of gold resources in Guinea will be discussed, including the challenges to better understand these gold-bearing resources.
