Featured Graphite Company

DNI Metals Inc. logoDNI Metals Inc.

Canadian-based DNI Metals Inc. is focused on developing a vertically integrated graphite company, with an emphasis on saprolitic-hosted deposits in Madagascar and Brazil.

Saprolite, or weathered material, will allow DNI Metals to extract graphite with much lower capital expenditure and operating expense costs than the overwhelming majority of their competition.

Their vision is to become the lowest cost, highest margin, highest quality graphite producer to take advantage of the clean energy segment: fuel cells, Li-Ion batteries, energy storage, etc., as well as traditional graphite sectors, such as: refractories, powder metallurgy, recarburisers, foundries, etc.

DNI Metals Inc. - Vohitsara Madagascar Graphite Property

Vohitsara (PE38642) Graphite Property in Madagascar

Their flagship project. Initial exploration results have indicated the presence of a reasonable quantity, quality, and tenor of natural flake graphite mineralization consistent with the high-quality of flake graphite found in central-eastern Madagascar.

The property has a commercial, exploitation mining permit from the BCMM (Bureau du Cadastre Minier de Madagascar), and DNI Madagascar Sarl - a wholly owned subsidiary - has been formed in order to carry out business in that country.

In March 2017, DNI Metals signed a DA (Definitive Agreement), with Australian-based Cougar Metals NL (ASX:CGM) to develop the Vohitsara Graphite Project.

Cougar has begun a 3,000 meter drilling program, and a 1,000 meter trenching program, to be followed by a NI 43-101 resource study, and a NI 43-101 PEA (Preliminary Economic Assessment). Pursuant to the DA, this work should be completed by late 2017. Upon completion of the PEA, a 50/50 Joint Venture will be immediately formed between DNI & Cougar.

Cougar's metallurgical tests have produced very high grade concentrates, with over 98% Total Graphitic Carbon, from both high and low grade raw composites, with 28% > 500 µm (Super Jumbo flake) and 65% > 180 µm (Large flake).

DNI Metals Inc. - Madagascar Graphite

Samples of strong graphitic carbon head-grade results (3% to 13.14% Cgr) from 4 trenches covering a strike length of 700 meters, averaging 300 to 400 meters in width, at Vohitsara, yielded the following preliminary results:

Flake Distribution, Description, and Size

  • 25.3% Jumbo +30 mesh / +595 microns
  • 29.5% Jumbo +50 mesh / +297 microns
  • 12.6% Large +70 mesh / +210 microns
  •  9.9% Medium +100 mesh / +149 microns
  •  5.8% Small +140 mesh / +105 microns
  • 16.9% Small -140 mesh / -105 microns

DNI Metals Inc. - Marofody Madagascar Graphite Property

Marofody (PE8904) Graphite Property in Madagascar

DNI Metals Inc. has signed a LOI (Letter of Intent) on this claim, which is contiguous to their Vohitsara property. With this addition, DNI will have a contiguous mining tenement package comprising nearly 70 square kilometers.

Graphite mineralization in Madagascar is concentrated primarily in the central and eastern coastal areas of the country, within graphitic horizons of the highly prospective Manampotsy Formation between Toamasina (Tamatave), Brickaville and Moramanga. Most of the mineralization remains underground, or unexploited, with substantial quantities still available for commercial mining. The bulk of the deposits in the Toamasina-Moramanga belt form topographic highs that can be stripped via free-dig methods, allowing for very economic ore extraction.

Both DNI Metals projects lie in a well-defined belt, between Toamasina (Tamatave) and Brickaville, which has been producing graphite for over 50 years, with both claims having historical mine workings on them. In addition, the claims are only 50 kilometers from Madagascar's main operating deep water port at Toamasina, via a paved national highway (Route Nationale No. 2).

Modular Graphite Pilot Plant

DNI Metals has recently announced that it will build a pilot plant for testing multiple zones in both Madagascar properties. The plant will be built in five ocean shipping containers, including flotation cells, and is designed to produce up to 6,000 metric tons of graphite per year, depending on the head grade. The modular plant is scheduled to be on the Vohitsara property before the end of 2017.

DNI Metals plans to expand output at 10,000 to 12,000 metric tons per year, which will enable the company to be extremely competitive in the current graphite market owing to its lower OpEx and CapEx costs, as the ore can go straight into the flotation process following excavation.

Future expansion plans include building a processing plant where ore from their Madagascar properties can be processed and upgraded, saving the company and its shareholders a great deal of money, resulting in higher profit margins for DNI in both the expandable and spherical graphite markets.

Every producing graphite mine must certify its products for carbon content, ash content, moisture content, particle size, and impurities. By having their own plant/laboratory, experts, and a training facility, DNI will be able to provide its customers with a secure, reliable, and consistent supply of graphite.

MOU with Peninsula Mines Ltd. (Expandable Graphite)

DNI Metals has signed a non-binding MOU (Memorandum of Understanding) with Australian-based Peninsula Mines Limited (ASX:PSM) to form a cooperative joint venture to supply and potentially produce, initially up to 20,000 metric tons per year of >180 micron, >95% TGC (Total Graphitic Carbon) large flake graphite concentrate, beginning in 2018.

The parties agree to identify scope to significantly increase supply to meet projected demand for large flake graphite concentrate to supply expandable flake graphite and/or other graphite products production in South Korea.

Under this agreement, the two companies aim to initially supply large-flake graphite from Madagascar, or elsewhere, to meet the required specifications for production of expandable graphite, as defined in the offtake agreements to be entered into by the parties, including the criteria as stipulated in the offtake Memorandum of Understanding signed by Peninsula Mines with Korean expandable graphite producer, Graphene Korea Co., Ltd.

The MOU is intended to form the basis of a binding flake graphite concentrate supply/offtake joint venture that the parties will use their best endeavors to complete within six months of signing this agreement.

Peninsula Mines Ltd. is an Australian exploration and development company focused on opportunities for mineral discovery and production in South Korea. They are established in South Korea, having worked there for over five years.
