1. Vohitsara Graphite Project - Madagascar

Initial drilling and resource complete. 

Dan Weir, CEO, commented, “When comparing one graphite deposit to another it is important to look at multiple factors:


  1. The Grade

  2. The size, and potential size of the deposit.

  3. Flake size distribution.

  4. The host rock - Hard rock verses, Weathered rock.

  5. Metallurgy.

  6. Infrastructure.

  7. Historical mining, or current mining in the area.

  8. People involved in the project.”


DNI has assembled a strong knowledgeable graphite development team who have built four graphite processing plants and operated two graphite mines.


The team chose this part of Madagascar because it has the potential to host graphite projects which could be developed into producing mines.


Graphite has been produced in the area for over 100 years with some of the historical production occurring on DNI’s properties.


Highlights from the resource study are as follows:


  • Main Zone: Inferred Mineral Resources of 4 Million tonnes (“Mt”) at 5% Graphitic Carbon, (“GC”) using a 3% GC Cut-Off Grade Base Case

  • Potential for further growth along north-south strike length

  • A saprolitic deposit is easier to mine and process than a similar hard rock graphitic deposit.



  1. The drilling program on the Main zone that was completed in 2017, covered a length of approximately 750 metres.  The Main zone is open ended.

  2. The Marofody project has historical production.  It has historical mapping to show the possibility of multiple mineralized zones.  Further testing is needed, and will commence in 2019, to analyze these zones.

Metallurgical Testing – 65% Large and Jumbo Flake


  1. Metallurgical testing was performed by Cougar Metals and IMO of Australia, and was Press released by DNI on June 19, 2017

  2. Metallurgical Tests have produced high-grade concentrates (>98% Total Graphitic Carbon) from both high and low-grade raw composites

  3. Conventional Flowsheet utilized with minimal grinding

  4. The high-grade sample produced a concentrate with 28% >500 µm (Super Jumbo Flake) and 65% > 180 µm (Large Flake), at an overall concentrate grade of 98.4% Total Graphitic Carbon

  5. The low-grade sample produced a concentrate with 53% mass > 180 µm (Large Flake) at an overall concentrate grade of 98.3% Total Graphitic Carbon

  6. Results achieved at a coarse grind size of 1 mm

Pilot Plant is designed ready to be built

DNI's next step is to build a 6,000 tonne per year pilot plant than can then be used as part of our commercial operations as DNI expands to 20,000+ tonnes per year.

The environmental permitting process is complete, except for the final sign off from the Minister of Mines.

A new government was elected in January of 2019 and they have put all permits on hold pending a review of the mining laws.

2. Marofody Graphite Project - Madagascar

Exploration project next to the Vohitsara Project.  Makes a contiguous land package of over 63 km2.  Historic mining, huge potential.

DNI’s Vohitsara and Marofody Graphite Projects in Madagascar


  • 50kms to Madagascar’s main port, on a paved road.

  • This part of Madagascar sees high annual amounts of rainfall and a hot climate, which weathers the rock in a saprolitic form, making the mining and the processing of the material easier than hard rock.

  • Mining friendly jurisdiction. 

  • Two operating graphite mines in the area. One 20 kms north, and the second 50 kms to the south.
