Madagascar graphite is renowned for its quality and flake size. For almost a century, Madagascar has been exporting flake graphite to the world but only in very small quantities from privately owned mines. That is about to change.
The Molo Project represents the first and substantial maiden discovery of high-quality graphite in Madagascar in decades. Comprising almost 50 percent of premium-priced large and jumbo flake graphite, the Molo Project is blessed with an excellent flake size distribution and can produce a SuperFlake™ concentrate between 97% to 98% carbon purity with simple flotation alone.

In order to meet advanced testing requirements and validation from potential off take customers, large bulk samples of finished graphite were required. To satisfy this, NextSource Materials conducted the largest-known pilot plant operation of any junior graphite project globally, processing 200 tonnes of ore and producing 13 tonnes of finished SuperFlake™ concentrate.
Extensive independent testing by these potential off take customers verified that Molo's SuperFlake™ meets all the major demand market applications for natural flake graphite, namely refractories, anode material for lithium-ion batteries, expanded graphite for specialty graphite foils, and graphene inks.
The Molo ranks as one of the largest-known and highest-quality flake graphite deposits in the world. The Molo has a National Instrument (NI) 43-101 compliant total combined graphite resource of 141.28 million tonnes (Mt) at 6.13% total graphitic carbon (C), with a contained ore reserve of 22.44 Mt at 7.02%C.

The Molo Project is one of seven graphite zones verified on the property. While the Molo deposit is very large in tonnage, the actual footprint itself is surprisingly small.
Contained in an area of just 500 metres wide by 2000 metres long, the deposit is open along strike and at depth and is one half of a double-folded complex. This means that the Molo can easily be expanded to meet market demand as required.
And, as if the Molo is not already large enough, additional graphite trends extend off of it for over 50 kilometres. In fact, through detailed and extensive geological trenching and sampling, over 300 line kilometres of continuous graphite has been mapped on our property – all immediately at surface.
The Molo deposit (red) is 500m x 2000m in size, and there is over 300 line kms of continuous graphite that is unidentified, immediately at the surface (green).
The Molo is perfectly situated for low-cost, open-pit mining. The resource is immediately at the surface, with minimal overburden, and a negligible stripping ratio.
As a Feasibility-stage project, the Molo Project been verified to have operating costs (OPEX) in the lowest quartile and can compete directly with Chinese flake graphite pricing.
The Molo Project will use the Port of Ehoala at Fort Dauphin. A modern deep-water port built by the World Bank and Rio Tinto in 2009.
After the release of NextSource’s robust Full Feasibility Study in 2015, an extensive 18-month value engineering exercise was undertaken in order to further optimize the Project’s positive economics.
It revealed that utilizing a two-phase, modular build approach would provide the most efficient and cost-effective solution to building a mine.
NextSource has assembled a specialized team of structural, mechanical and process engineers along with a leading modular solutions technology provider and will be delivering to the industrial minerals industry a mining first: the achievement of a full-scale, permanent graphite mine utilizing cutting edge modular supply and modular build technology.
