Black Rock Mining Limited (ASX:BKT) is focused on developing its Mahenge Graphite Project, which holds the largest high-grade flake graphite resource in Tanzania – the third largest contained graphite resource in the World. The Mahenge Project is undergoing a Pre Feasibility Study (PFS) which is due for completion in November 2016, following positive scoping study results released March 2016. The PFS is expected to roll directly into a DFS.
A global Mineral Resource of 162.5Mt at 7.8% TGC holds 12.7Mt of contained graphite. This extensive resource contains a high-grade portion of 38.7Mt @9.9% TGC, or 13.5Mt @10.7% TGC. Current drilling at the Cascades zone is expected to deliver higher grade resources by the end of 2016.
Metallurgical test work indicates excellent flake size and quality with up to 99.1% TGC concentrates produced from a simple four stage flotation process. This sector leading purity provides potential to manufacture battery grade spherical graphite with minimal chemical purification or to possibly substitute chemical with cleaner thermal purification. Spherical graphite and expandable graphite have been produced from Mahenge concentrates with superior technical specifications.
The large resource with high-grade zones, high proportion of coarse flake and potential to produce exceptionally high purity coarse graphite flake offers flexibility to develop a long life mine that can supply high quality graphite products to customers for decades.
