SnapshotBunyu is one of the largest graphite deposits in the world.

Having commissioned Bunyu Stage 1, Volt intends to move to Stage 2 later this decade with the goal of leveraging the platform established by Stage 1, and Bunyu’s status as one of the largest graphite resources globally, to dramatically scale production from 24,780 to 170,000 tonnes per annum and help meet the forecasted global increase in demand for graphite products.

Environmental Impact Assessment Certificate and Mining Licences received covering both Stage 1 and 2.

As of January 2024, Volt Resources has been delivered graphite concentrate to the customer. Volt Resources expect to get the customer feedback before 29 March 2024. The company believes that successful completion of product qualification by the customer will enable it to secure the Bunyu Project financing.

Deposit type

  • Metamorphic

Summary:

The graphite mineralisation occurs in Archean basement rocks of the Mozambique Belt system which principally comprise metamorphic rocks ranging from schist to gneisses including marbles, amphibolite, graphitic schist, mica and kyanite schist, acid gneisses, hornblende, biotite and garnet gneisses, quartzite, granulite, and pegmatite veins.

Exploration has focused on areas where there is no or minimal overlying younger sedimentary sequences remaining (mostly Cretaceous sandstones and conglomerates).

Dimensions
• The main zones of mineralisation extend over an area of 3 km along strike, 800 m to 1.3 km across strike and from surface to a drilled depth of approximately 150 m below surface.

• The Bunyu 1 mineralisation remains open to the north-east (where it is under a thick sedimentary sequence), to the south-west and at depth.
