ABSTRACT:Black Rock Mining Limited (ASX.BKT) (“Black Rock Mining” or “the Company”) is pleased to announce the Ulanzi infill drilling Mineral Resource upgrade from its Mahenge Project in Tanzania. The global Mineral Resource of 162.5 Mt@ 7.8% TGC hosts 12.7Mt of contained graphite, confirming the Mahenge Project as being the largest and highest grade flake graphite resource in Tanzania. In Global terms, Mahenge is the third largest JORC compliant graphite Mineral Resource in the World. This offers significant flexibility for potential development into a long life (+30 year) mining operation. It has potential to be mined from multiple zones at low strip ratios, high-graded to accelerate capital payback in early years and can be scaled up in future due to the large resource size. Extensive metallurgical test work indicates that high purity concentrates in the 99% TGC range can be made from a straightforward flotation circuit for both oxide and fresh mineralisation. An extensive spherical and expandable graphite assessment programme indicates that Mahenge graphite can make premium products. The Pre Feasibility Study (PFS) will be released in November and the Definitive Feasibility Study (DFS) is expected in March 2017. Our objective is to commercialise the Mahenge Project by taking it into production. Chairman Stephen Copulos commented: “The upgraded Mahenge resource is an excellent development for Shareholders. This provides a higher level of resource confidence and development flexibility - with additional upside expected from Cascades. The large resource with significant higher-grade portions and straightforward metallurgy are the key building blocks for the current PFS, planned for release in November this year. The September $5m capital raising puts the Company in a sound position to continue its development programmes with independent expandable and spherical graphite test results continuing to generate highly positive results and offtake interest.”
