Bunyu Graphite Project

Highlights of the Bunyu Graphite Project

  • Upgraded project JORC Resource estimate to 461Mt @ 4.9% TGC
  • Volt now has the largest Mineral Resource in Tanzania (reported to the standard of the 2012 JORC Code)
  • The recently completed Bunyu PFS results have a robust Pre tax NPV of US$1.31B, 87% IRR and pay-back of 1.4 years based on 22-year LOM based on optimised Measured, Indicated and Inferred Resource categories
  • Maiden JORC Ore Reserve is 127Mt @ 4.4% TGC
  • Outstanding flake distribution of up to 81.3% in the Super Jumbo, Jumbo, Large flake categories
  • Excellent purity achieved without the use of chemicals - only crushing & flotation
  • Futher optimisation of the flotation flow sheet is ongoing to further improve purity and recovery
  • Project scale which complements global marketing drive and strategy to fast track project development

Why Tanzania?

Tanzania has a well-established mining & service industry

PESTEL analysis: Politically stable and enjoys solid economic performance

Tanzania Map
Politics Relatively stable democracy since the 1960s & English speaking
Strong and successful purge against corruption (IMF Apr 2016)
Economics Impressive Economic performance (GDP +7% 2015) (IMF Apr 2016)
Top sectors construction, communication, finance and transportation
Social Mixture of Bantu, Arab and Western cultures
Technological Undergoing a rapid change due to rise in GDP
Environmental Framework in place for environmental laws
Legal Common law system


The map below shows the location of the Bunyu Graphite Project tenements and the main graphite prospects that have been identified to date.

These lay within the 2000km2 of the company's tenement package. Volt Resources has continued to build on its dominant tenement position in this extremely well located, high quality graphite area of Tanzania.



  • The Project is approximately 10km from the sealed road and 140km from the deep water Mtwara port
  • Mtwara Port has a current annual capacity of 400,000 tonnes with the ability to expand to 750,000 tonnes without the need for additional berths. It is presently underutilised with only 34% of its capacity in use.
  • A reliable power solution and access to water supply is available.


The total resource (Measured, Indicated and Inferred) of 461Mt at 4.9% TGC has been estimated to JORC 2012 reporting guidelines for the combined Bunyu North (Bunyu 1) and Bunyu South (Bunyu 2 and 3) resource. Volt’s resources at Bunyu North & South is based on the drill hole information below.

Table A: Drilling program for 2016

Deposit RC Drilling Diamond Drilling Water Bore Drilling
Holes Metres Holes Metres Holes Metres
Bunyu One (North) 76 5,070 19 1,708 5 346
Bunyu Two 63 3,894 15 827 - -
Bunyu Three 37 2,873 5 293 - -
Total 176 11,837 39 2,829 5 346

In the above table, the mineralisation intersected showed significant extension areas and confirmed Bunyu to be a very shallow resource (<100m); as such it is considered a low cost deposit to explore and mine.
