NextSource Materials Announces Initiation of Civil Works and Shipment of Buildings to the Molo Graphite Mine Site in Madagascar and Filing of Updated PEA

TORONTO, ON / ACCESSWIRE / April 28, 2022 / NextSource Materials Inc. (TSX:NEXT) (OTCQB:NSRCF) ("NextSource" or the "Company") is pleased to announce that its construction team is now setup at the Molo Graphite Mine site in Madagascar and civil and earthworks have been initiated in preparation for the delivery and installation of the processing plant. The offsite fabrication and construction of the auxiliary buildings and structures has also been completed and these are in the process of being delivered to the mine site.

President and CEO, Craig Scherba commented,

"With the mobilization of construction crews to the mine site and initiation of civils and earthworks, we have reached yet another key milestone towards commissioning of the Molo Graphite mine later this year."

Work crews have begun civil construction and earthworks, utilizing heavy construction equipment to prepare the ground for the delivery and installation of the processing plant and auxiliary buildings. The work will involve:

  • site stripping and leveling
  • laying of foundations for buildings and structures
  • excavation for utility installation
  • road remediation

The Phase 1 processing plant was designed and built using an all-modular approach and is capable of processing 240,000 tpa of ore and producing approximately 17,000 tpa of high-quality SuperFlake® graphite concentrate. On February 28, 2022, the Company announced the processing plant, which was fully assembled at an offshore facility and had successfully passed factory acceptance testing and final verification, had been dismantled, packaged, and is ready to be shipped to the mine site. The processing plant is expected to be delivered to the mine site in Q2 2022, followed by installation and commissioning in Q3 2022.

The following auxiliary buildings and structures are expected to be delivered and installed at the mine site during Q2 2022:

  • Accommodation camp
  • Water treatment plant
  • Sewage treatment plant
  • Plant offices
  • Plant workshop
  • Testing laboratory
  • Plant ablutions
  • Change house

Once Phase 1 of the Molo Graphite Mine is completed and commissioned as expected in Q3 2022, it will become one of the few operating graphite mines outside of China.


The Company announces updated results for the Phase 2 Preliminary Economic Assessment (the "PEA") for an enhanced Phase 2 expansion of its 100%-owned Molo Graphite Mine Project. The original results were press released on February 28, 2022.

The PEA considers an enhanced Phase 2 expansion consisting of a stand-alone processing plant with a production capacity of 150,000 tonnes per annum ("tpa") of graphite concentrate over a 26-year life of mine ("LOM"). The PEA assumes the Phase 2 processing plant is built adjacent to the Phase 1 processing plant currently under construction.

The PEA was updated to reflect changes to the processing plant power cost assumptions involving the consumption of diesel fuel. The PEA estimated that Phase 2 capital costs will be US$155.8 million (no changes) resulting in a pre-tax NPV utilizing an 8% discount rate of US$904.8 million (previously US$929.6 million) and a pre-tax IRR of 40.4% (previously 41.1%), the details of which are set out in the PEA. The original press release stated an incorrect average stripping ratio, which is corrected in the table below with no impact on the PEA results.

The following is a summary of the economic and operational highlights in the updated PEA that considers the increase in the power cost assumptions, as compared to the previously released results, and which supersedes the previously released results:

The PEA has been filed and is now available on SEDAR ( and is also available on NextSource's website at The PEA was prepared by Erudite Strategies (Pty) Ltd. ("Erudite") of South Africa, an independent engineering and consulting firm specializing in the mining and processing of commodities and battery materials.

The Company cautions that the PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral resources are not mineral reserves and do not have demonstrated economic viability and there is no certainty that the PEA will be realized.


The Company announces the initiation of a front-end engineering design (FEED) study and Feasibility Study for the proposed Phase 2 expansion of 150,000 tpa of graphite concentrate that was considered in the PEA. The Feasibility Study is expected to be completed by the end of 2022. Upon completion, the Company will analyze the results of the Feasibility Study prior to making a construction decision.


The PEA was prepared in accordance with National Instrument 43-101 standards by Mr. Johann de Bruin, Pr.Eng, of Erudite Strategies (Pty) Ltd. Please refer to the PEA titled "Molo Phase 2 Preliminary Economic Assessment" dated April 27, 2022 filed on the Company's profile at
