Summary:

The Yanfolila Greenstone Belt, which is orientated north-south on the eastern margin of the greater Siguiri Basin hosts the Project. This belt forms part of the Birimian Volcano-Sedimentary series of the West African Craton. The belt contains several sub-basins including the KMSB and the KSB. These sub-basins, and the eastern margin of the wider Siguiri Basin, are bound to the east by the SSZ and the Siekerolé Granite. The SSZ is the major basin-bounding structure in the region. Mineralisation is typical lode gold-style deposits structurally reminiscent of a foreland fold and thrust belt with a deformational framework similar to the hanaian Gold Province.

The KMSB hosts the majority of the Yanfolila gold deposits and targets currently defined. It has a stratigraphic sequence of basalt, polymict conglomerate, feldspathic sandstone, silt-shale, and a lithic-dominated greywacke. Mafic and felsic (porphyry, granodiorite, and diorite) intrusives crosscut the stratigraphy. Splays of the SSZ and regional-scale structures, which crosscut strata, control gold mineralisation. Gold is associated with rheological contrasting rock types that have been structurally deformed to provide fluid pathways from where any combination of disseminated, vein, breccia, intrusive, and replacement styles may evolve.

Outcrop is sparse throughout the basin and is mostly extensive lateritic and depositional terrains.

Lithologies at KW comprise interbedded siltstone and ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Yanfolila Gold Mine (‘Yanfolila’), located in southern Mali, is a high-grade open pit mining operation, with underground potential.

The Project will be developed by progressively mining five deposits: KE, KW, GW, SE, and SW. The Gonka deposit is also shown as it may be included in the Project at a later date. HUM will contract with a mining service provider to apply industry standard open pit mining methods to remove waste and ore from the deposits according to a mine production schedule. Mining methods will include excavating the soft oxidized ore near the surface, and drilling and blasting harder transitional and fresh rock. Haul trucks will follow haul roads to transport waste rock to engineered waste rock disposal facilities (WRD).
