Deposit Type

  • Metamorphic hosted


Summary:

The regional geology is comprised of late Proterozoic Mozambique mobile belt lithologies consisting of mafic to felsic gneisses interlayered with amphibolites and metasedimentary rocks. The mineralisation consists of a series of intercalated graphitic horizons within felsic gneiss (siliceous and aluminous rich sediments), amphibolites (mafic sourced material) and rarely high purity marble horizons.

In the Chilalo Main deposit the core high grade mineralisation (>5% TGC) interpretation consists of two lenses. The main footwall lens strikes towards 250°, dipping roughly 50° towards 160°, with a strike length of roughly 1.1 km from the north east towards the south west, and a further strike length of roughly 500m, after a strike change to 250° at about 471280mE with a dip roughly 40° towards 180°. The average interpreted depth is approximately 200 m below surface and the true thickness is approximately 25 m for the eastern half and 10 m for the western half. The secondary high-grade lens is interpreted to be approximately 1.1 km long in the hanging wall of the western two thirds of the main lens from roughly 471800mE extending to the west. It is interpreted to be between 40 m in depth in the east, and 160 m in depth in the west, and between 2 m and 15 m in true thickness with a similar strike and dip to the main lens. The low-grade mineralisation (>2% TGC) lenses enclose the high- grade lenses and are in the hanging wall above them and have similar strike and depth e ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Chilalo open pit mine is planned as a conventional truck and shovel operation, using 40-50 tonne articulated trucks and matching excavators. Early stages of the open pit are expected to be free-dig, with the remainder to be mined using standard drill and blast techniques. Contractor mining has been assumed for the life of mine. Investigation of owner operator mining, supported by a fleet of ancillary equipment, will be undertaken as part of the BFS.

The geotechnical parameters utilised in the pit design are as per the recommendations by Open House Management Solutions' geotechnical consultants.

Initial waste generated from mining is to be used for construction of the Tailings Storage Facility (‘TSF’) and thereafter to be dumped in a designed location outside of the pit.

Pit ramps have been designed with the following characteristics:

• The dual lane ramps are 15m wide to allow for safe passage of the selected trucks with an allowance for a bund wall on the open side of the ramp and a drain on the inner side.
• The single lane ramps are 10m wide can be used for mining last benches and good bye cuts.
• Gradient of 1:10 is practicable with the proposed mining fleet.
• Ramps exit the pit crest in the direction of both the ROM and waste rock dumps.

Minimum mining width of 30m is maintained for the cutback designs, however minimum 20m of mining width is maintained on normal benches. The waste dump will be ........

Reserves at August 28, 2019:
The Mineral Resource was estimated within constraining wireframe solids using a core high-grade domain defined above a nominal 5% TGC cut-off within a surrounding low-grade zone defined above a nominal 2% TGC cut-off. The resource is quoted from all classified blocks above a lower cut-off of 2% TGC within these wireframe solids.
