NextSource Materials Releases New Feasibility Study Incorporating Phased Buildout in Preparation of Mine Financing


  • The 2019 Feasibility Study (“FS”) outlines a phased development approach with Phase 1 producing 17,000 tonnes per annum (“tpa”) over the first two years of production and Phase 2 producing a total of 45,000 tpa by year 3.
  • Over the modelled life of mine (30 years), the production plants will have a pre-tax internal rate of return (“IRR”) of 43.1%, and a post-tax IRR of 36.2%. The pre-tax Net Present Value (“NPV”) at 8% discount rate will be US$237.1M, and the post-tax NPV will be US$184.3M.
  • The capital mine cost (“CAPEX”) for Phase 1 will be US$21.0M with Phase 2 CAPEX being an additional US$39.1M, for a total project cost of US$60.1M.
  • Both phases will utilize the Company’s unique, fully modular build approach, which greatly reduces build time and associated costs in relation to conventional mine construction.

TORONTO, Sept. 27, 2019 (GLOBE NEWSWIRE) -- NextSource Materials Inc. (TSX:NEXT) (OTCQB:NSRCF) (“NextSource” or “the Company”),  is pleased to report the results of its 2019 Feasibility Study  for its 100%-owned Molo Graphite Project in southern Madagascar. The FS takes into account updated mine capital equipment and mining costs, as well as current 12-month rolling flake graphite pricing on a FOB China basis, supplied by UK-based battery mineral commodities research firm, Benchmark Minerals Intelligence.

The FS was based on a Front End Engineering and Design study (“FEED”), and subsequent Detailed Engineering studies. The FS incorporates the procurement of all mining equipment, off-site modular fabrication and assembly, factory acceptance testing, module disassembly, shipping, plant infrastructure construction, onsite module re-assembly, commissioning, project contingencies and working capital. All capital and operating costs expressed for Phase 1 are considered to be accurate to +/- 10%, and accurate to +/- 12.5% for Phase 2.

In order to ensure that the Company maintains a first-mover competitive advantage over the competition and to appropriately plan for future market demand, the FS was designed to provide a flexible mine development approach that comprises a unique, all-modular build solution yielding optimal cashflow and return metrics with suitable flexibility to enable a rapid response to the anticipated market demand for graphite.

As previously reported to the market, the Company has an off-take agreement in place with a prominent Japanese trader, whom is a major supplier of flake graphite to Japan’s largest battery
processor and manufacturer of graphite anode material in lithium ion batteries (“LiB”) for electric vehicle applications. NextSource is currently in the process of formalizing an additional sales agreement with a leading European trader. As such, the FS was undertaken to include two phases in order to account for off-takers’ demand for NextSource’s SuperFlake® graphite concentrate.

PHASE 1: Production of 17,000 tpa

  • The first phase of production will consist of a fully operational and sustainable graphite mine with a permanent processing plant capable of processing 240,000 tpa of ore and producing approximately 17,000 tpa of high-quality SuperFlake™ graphite concentrate.
  • The updated build cost of the fully modular process plant marginally increased from the US$18.4 million reported in the 2017 FS to US$21.0M due to equipment cost inflation.

PHASE 2: Production Expansion to 45,000 tpa in Year 3

  • Phase 2 incorporates the processing of 240,000 tpa of ore (producing 17,000 tpa of SuperFlake® concentrate) for the first two years of operation and then ramping up to 720,000 tpa of processed ore in the third year to accommodate additional sales, resulting in a total of 45,000 tpa of SuperFlake® concentrate being produced for a mine life of 30 years.
  • The costing for Phase 2 is based on the addition of two modules of the beneficiation plant with a proportional increase in mining and infrastructure costs.
  • The capital mine cost for Phase 2 (with contingency) will be US$39.1M, for a total project cost (Phase 1 and Phase 2 with contingency) of US$60.1M.


  • The Phase 1 production plan of 17,000 tpa of finished SuperFlake® concentrate for the first two years of production followed by a ramp-up to Phase 2 production of 45,000 tpa yields the following financial metrics.

Craig Scherba, P.Geo., President and CEO of NextSource commented,

“Our Feasibility Study will greatly assist us in our current discussions with mine financiers, and reconfirms to the market the economic viability of the Molo project under current market conditions. Our all-modular build strategy has low capital and operating costs, and a rapid build time. With our phased build-out, this will allow our graphite to be easily absorbed into the current market while maintaining NextSource’s flexibility and competitive advantage to quickly penetrate the market and generate revenue, establish strong relationships with as many key buyers as possible, and verify our product for highly technical markets with production-run material.”


The Mineral Reserves and Mineral Resources did not change as a result of the FS.  As disclosed in the Company’s 2015 Molo FS, the following are the proven and probable mineral reserves.

Category Tonnage C Grade (%)
Proven 14,170,000 7.00
Probable 8,367,000 7.04
Proven and Probable 22,437,000 7.02

(1) Proven reserves are reported as the Measured Resources inside the designed open pit and above the grade cut off of 4.5% C. Similarly, the Probable Reserves are reported as the Indicated Resources inside the designed open pit and above the grade cut-off of 4.5% C. Mineral Reserves are effective as of August 14, 2014.


The Molo project hosts the following mineral resources:

  • Measured mineral resource of 23.62 MT grading 6.32% C.
  • Indicated mineral resource of 76.75 MT grading 6.25% C.
  • Inferred mineral resource of 40.91 MT at 5.78% C.

Effective date of the Mineral Resource tabulation is August 14, 2014. The Mineral Resources are classified according to the Canadian Institute of Mining definitions. A cut-off grade of 4% C was used for the “higher grade” zones and 2% C for the “lower grade” zones.  Please note that while the ‘high’ grade resource occurs within the ‘low’ grade resource, each was estimated and reported separately. A relative density of 2.36 tonnes per cubic metre was assigned to the mineralized zones for the resource estimation.  The resource remains open along strike and to depth. The Mineral Resources are inclusive of the Mineral Reserves above.  Mineral Resources reported herein include Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

The FS is based on a full suite of metallurgical test work performed by SGS Canada Metallurgical Services Inc. in Lakefield, Ontario, Canada. These tests included lab and bench scale process development work, a bulk sample/pilot plant program, and metallurgical variability testing. The overall graphitic carbon recovery into the final concentrate is 88.3%.

The selling price used in the FS is the volume weighted average sales price for the various flake sizes and grades of SuperFlake™ graphite concentrate that are expected to be produced from the Molo deposit. This price is based on 12-month rolling graphite prices provided by UK-based Benchmark Minerals Intelligence who are recognized as leaders in providing independent and unbiased market research, pricing trends and demand and supply analysis for the natural flake graphite market.

No pricing premium for valued-added applications was applied on any sales. Furthermore, no financial or operational calculations and/or scenarios in the FS financial model with regards to downstream value-added processing of SuperFlake™ graphite concentrate were included. This includes purification, spherodization coating for battery-grade graphite and thermal expansion for specialty graphite applications, such as foils.


All environmental and social responsibility information for the Molo Project has been completed to Equator Principles, which are the standards adopted by the majority of international commercial banks, as well as the International Finance Corporation’s (IFC) Performance Standards. They are the highest environmental and social standards in the world. These standards have been incorporated into the design of the Molo Project’s facilities and operations given NextSources’ commitment to follow international best practices.  There is a global consumer shift to take social responsibility into account when developing projects and NextSource has worked hard to ensure that it met this requirement.
