Black Range Graphite Project

 

The Black Range flake graphite prospect was discovered in the late 1980’s and was explored by Rossing Uranium Ltd. Between 1988 and 1992.  Roessing interpreted the graphite horizon in a fold structure  with a fold length of about 8 km.  Based on 3 821 metres of percussion drilling and 3 931 metres of diamond drilling from a 1 km segment of the horizon employing a cut-off grade of 2% graphitic carbon and using a polygonal section method, an historic estimate of 12.46 million tons grading 4.63% graphitic carbon was utilized by Rossing to assess the project.

 

Preliminary mining plans were drawn up and preliminary metallurgical work was carried out by Mintek in South Africa but the project was terminated before the flowsheet was fully optimized when the decision was made to focus instead on the graphite deposit at Okanjande.  The Okanjande deposit was brought into production in 2017 be Gecko Namibia in a joint venture with Imery Carbon and Graphite.

 

Black Range is slightly lower grade than the producing Okanjande Graphite Mine, but the potential resource is much larger than the 1 km strike length that has been tested to date.
