Deposit Type

  • Orogenic
  • Mesothermal
  • Vein / narrow vein


Summary:

DEPOSIT TYPES
Three types of gold occurrences may be expected at Kobada:
• Primary lode gold mineralisation, associated with quartz veins and fault zones related to one or several Eburnean deformation phases (orogenic gold, shear zone gold or mesothermal gold deposits). Deposits of this typeoccur in the surrounding area.
• Lateritic deposits, resulting from the climatic weathering and alteration of primary deposits with diffusion of the gold into mushroom-shaped red oxidation zones (saprolite).
• Placer deposits, where the gold is associated with large angular fragments of quartz and intensely silicified pyritic rocks in alluvial sand and gravel horizons usually several metres in thickness. These fragments are derived from proximal lode deposits.

Placers are present on the Project and have been worked by artisanal miners for a long time.

The Kobada gold deposit is a quartz-carbonate veined mesothermal, orogenic gold deposit hosted within a greenstone belt. It is located in arenites affected by a geological structure that is oriented northeast along the border of an intermediate intrusive that has basic components. Mesothermal veins are formed at moderate temperature and pressure, in and along fissures or fractures in rocks. They are known for their large size and continuation to depth and, therefore, are a major source of the world’s gold production. Veins are usually less than 2 m wide and often occur in parallel sets.

Mining Methods

  • Truck & Shovel / Loader


Summary:

The Kobada Open-Pit Project is an approximately 16-year LOM operation including the preproduction period. The mine will need to support a processing plant with a nominal mill feed of 3 Mt/a of ROM.

The mineralised material contained within the final pit design has been determined based on a 0.35 g/t gold COG. All Inferred Resource materials are treated as waste in the pit optimisation. The mill feed is made up entirely of Measured and Indicated Resource materials (laterite, saprolite, transition and sulphide) above the calculated COG.

The Kobada Gold Mine lends itself to a standard open-pit mining method using articulated trucks and a hydraulic loader (hydraulic shovel or excavator).

Approximately 90 % of all the materials to be mined is contained in the saprolite and laterite. Although this type of material can be extracted directly with excavators without drilling and blasting, it has been estimated that approximately 5 % of this material will require some drilling and blasting. All transition and fresh rock material must be drilled and blasted.

The first six months will be exclusively dedicated to pre-production without feeding the process plant.

From Year 1 to Year 8, the process plant will be fed mainly with high-grade oxides from the pit and supplemented by the ROM stockpile.

From Year 9 to Year 11, the process plant will be fed mainly with high-grade sulphides from the pit and supplemented by the ROM s ........

Projected Production:
The Kobada Gold Project, when completed, will produce 100 000 oz/a of gold via a conventional gravity carbon-in-leach (CIL) process designed to treat 3 Mt/a of run of mine (ROM) for the first 10 years of production, followed by low gold production as a result of treating low grade ore.
