Deposit Type

  • Metamorphic


Summary:

Disseminated graphite flakes occur in two main layers between about 20 and 40 m apparent thickness hosted within granulitic gneisses. The mineralised zones strike NNW and dip at ~45-75° to the ENE and have been traced by mapping, trenching and drilling along approximately 1,300 m strike length.

The graphitic and waste rocks are weathered to varying depths across the deposit and may be described as oxidised, transitional or fresh. The oxidised domain is characterised by the oxidation of sulphide minerals, e.g. pyrite, and by the formation of secondary sulphate minerals such as jarosite and hydrous clay minerals such as goethite, smectite and kaolinite.

The central part of the western graphite zone was intruded by granitic material which has displaced or stoped away the graphite mineralisation. Marble layers are noted in the hanging wall of the east graphite zone; some of these were originally logged as granite with xenoliths but were later verified to be calcium carbonate with ‘xenoliths’ rich in clinopyroxene. Marble may be useful for neutralising any acid forming (sulphide-bearing) rocks or waste generated during future mining activities. A garnetiferous marker layer has been noted along the base of the eastern graphite zone. The graphite schists and gneisses are generally underlain by a monotonous sequence of grey granulite and gneiss lithologies.

The general geological continuity along strike is verified by the drilling pattern and the appa ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Project comprises two main deposits – Razafy and Razafy Northwest (NW), broadly 1.5km apart, spread out over approximately 2km2. An initial 0.5Mtpa process plant will be located about 0.5km north of Razafy, to be expanded to 1.0Mtpa in Year 3, ready for milling 1.0Mtpa from Year 4 onwards – staged development.

It is envisaged that two waste dumps will be constructed at Razafy, a smaller one to the east and a larger one to the west of the pit. A single waste dumps will be constructed at Razafy NW.

Mining will be carried out using conventional open pit methods of drill and blast followed by load and haul.

The total material movement at the Project has been estimated at approximately 2Mtpa for the first three years of operation, increasing to a maximum of 4Mtpa in subsequent years.

It is believed that a mining fleet comprising 60t to 80t excavators and 30t to 40t capacity trucks would be suited for the scale of mining envisaged.

The mining operation would excavate and load the ore and waste in accordance with the marked ore and waste boundaries and ensure minimum dilution and maximum recovery of ore.

The ore is to be hauled to a single ROM pad located to the north of Razafy and east southeast of Razafy NW.

The bulk of the waste will be dumped in areas adjacent to the pits, with 26% required for constructing the TSF embankment and 3% for other mining related infrastructure such as the Run of Mine (“ ........


Crushing and Grinding
Flow Sheet: Source

ROM ore at 6.3% to 10.3% TGC is crushed in a two-stage crushing and screening plant and then conveyed to the primary milling circuit where it is milled in a closed circuit to further liberate and prepare the ore for flotation.
