The Baniaka Project will produce greener, higher value iron ore products with lower carbon intensity.
During the Fourth Quarter 2023, Genmin was granted the Mining Permit for Baniaka. The Mining Permit in conjunction with the Certificate of Environmental Conformance received in August 2023, provides regulatory approval for Genmin to build and operate Baniaka. |

Summary:
Deposit Type
Baniaka is located within the Chaillu Massif, where the Archaean basement comprises granitoids and gneisses with greenstone belts consisting of metasediments and metavolcanics including amphibolites, quartzites, micaceous schists and banded iron formation (BIF).
Iron mineralisation at Baniaka is associated with an eluvial and/or colluvial accumulation of iron-rich fragments derived from erosion of the underlying iron-enriched BIF units (DID), oxide BIF (SO and Intact Oxide), and primary BIF (Primary)). The DID and Oxide BIF are enriched in iron compared to the Primary, with in-situ grades of 40–50% Fe and 40–45% Fe, respectively, and 33% Fe for the Primary.
The BIF units are hosted in, and concordant with, felsic schists and para-gneisses with lesser amphibolite occurrences. Primary iron mineralisation is present as magnetite. The BIF units, wall rocks and early granitoids have been metamorphosed and have undergone multiple phases of deformation. Two (2) early phases of deformation show plunging, tight to isoclinal folds, boudinage structures and shearing. Two (2) later phases of deformation comprising open to gentle folding are also recognised. The metamorphic grade is Lower Amphibolite Facies.
The fault network of the PFS Prospects is well defined and pervasive, however faults have minor offsets of less than 15m. Younger brittle faulting, possibly related to the formation of the Francevillian basin to the north, and late ........
Summary:
The Baniaka Project assumes conventional truck and shovel, shallow, free dig contract open pit mining operation, over an initial 10-year mine life.
The optimal pit mines 140Mt at a strip ratio of 0.21 (Waste to Ore) and an average processed Fe grade of 45.5%. Phase designs were completed to provide a practical mine design and aid in the creation of the production schedule. The larger areas were split into phases approximately 1km in length. Each phase design incorporates appropriate twin access ramps and a mining strategy that provides for both in-pit and ex-pit haulage of ore and waste.
Main haul roads were designed at 25m wide to accommodate two-way traffic for a Caterpillar 777 haul truck. Road widths of 15m have been designed for lower levels to minimise waste stripping and maximise ore extraction. Switchbacks have been designed to an inner radius of 25m and a minimum mining width of 20m has been implemented.
Waste rock encountered while mining is to be used for the construction of mine haul roads and embankments. Haul roads have been designed to a 10% gradient. Cut and fill is required to optimise haulage and trafficability in the undulating terrain. Additionally, a surface water assessment identified areas requiring embankments to prevent encroachment of water into the mining areas.
The waste rock dumps have been designed with embankments composed of colluvium and bedrock material to contain Loess material and to maximise ........

Reserves at November 16, 2022:
Ore Reserve Estimated with break-even cut-offs for average grade material by ore type have been estimated at the rate of 29% Fe for DID, 29% Fe for HYB and 25% Fe for Soft Oxide.
Mineral Resources are reported at a head grade of 40% Fe, most samples have a large recoverable fragment content. Where samples contain at least 25% of =1 mm eBIF fragments but grade is less than 40% Fe, mass yield is lower, but the recovered product remains saleable
Mineral Resources are reported inclusive of Mineral Reserves.
