Okanjande Graphite Deposit and Okorusu Processing Plant

NI 43-101 Report

Northern’s Namibian operations consist of the Okanjande graphite deposit, located 14 km south of the town of Otjiwarongo, and the Okorusu processing plant where ore will be transported for graphite recovery.  The plant is currently undergoing capital improvements and is expected to be back in operation within nine to 12 months at a rate of 30,000 tpy.  Northern’s ultimate plan is to build a large, new processing facility at the Okanjande mine which will be capable of producing up to 150,000 tpy to meet growing battery/EV demand.

Highlights

  • Namibia is one of the best jurisdictions in Africa in which to operate
  • Okanjande graphite is of the highest quality
  • The Okanjande deposit has substantial measured and indicated resources and a low waste to ore ratio
  • The operation has access to grid power
  • The deep water port of Walvis Bay is five hours away (388km) over good roads which provides ready access to European and North American markets. 

The above attributes, plus a much shorter time to market, provide a competitive advantage over other African graphite projects. 

Namibia

Northern Graphite acquired its Namibian operation in April 2022 from Imerys Group. It consists of the Okanjande graphite deposit and a processing facility located 78 km away at the idle Okorusu Fluorspar Mine (pictured above).

Mining operations began at Okanjande in 2017.  Up until November 2018 the material was trucked to Okorusu which had been retrofitted to process graphite bearing material. The processing plant did not perform to expectations and was put on care and maintenance at that time.

Northern has developed a plan to modify the Okorusu processing plant to increase throughput and recovery and improve the flake size distribution.  The plan, which will cost approximately US$14 million and take up to twelve months to implement, will bring the operation back into production at a rate of approximately 30,000tpy. 

Northern’s ultimate plan is to build a large new processing plant adjacent to the Okanjande deposit to produce 100-150,000tpy of graphite concentrate to meet rapidly growing EV and battery demand.

The Geology

The Okanjande/Okorusu operation is based on a weathered, measured and indicated resource of 6.1 million tonnes (“Mt”) grading 4.7% graphitic carbon.  There is also an inferred weathered resource of 1.2Mt grading 3.9% and a number of “weathered” exploration targets outside the main deposit.  The weathered resources overlie fresh rock, measured and indicated resources of 28.8Mt grading 5.3% (1.5Mt of contained graphite) and fresh rock inferred resources of 24.3Mt grading 4.5% (1.1Mt of contained graphite).  All resources were calculated with a 3% cut off grade and have not yet been closed off by drilling.
