TORONTO, ON / ACCESSWIRE / February 28, 2022 / NextSource Materials Inc. (TSX:NEXT) (OTCQB:NSRCF) ("NextSource" or "the Company") is pleased to announce the results of a Preliminary Economic Assessment ("PEA") for an enhanced Phase 2 expansion of its 100%-owned Molo Graphite Mine Project in southern Madagascar.
The PEA considered an enhanced Phase 2 expansion consisting of a stand-alone processing plant with a production capacity of 150,000 tonnes per annum ("tpa") of flake graphite concentrate over a 26-year life of mine ("LOM"). The PEA projects that the capital costs to construct 150,000 tpa of processing capacity would be US$155.8 million with a pre-tax NPV utilizing an 8% discount rate of US$929.6 million and a pre-tax IRR of 41.1%.
The PEA assumed the Phase 2 processing plant will be built adjacent to the 17,000 tpa Phase 1 processing plant, currently under construction.
Craig Scherba, P.Geo., President and CEO of NextSource commented,
"We are very pleased the PEA defines the strong financial returns of a larger scale operation and significant scalability of our project as market demand for flake graphite for use in electric vehicle batteries is rising. A Phase 2 expansion of this magnitude will position NextSource as a major global supplier and will underpin our vertical integration strategy to construct our own battery anode facility in due course, enabling direct supply to the electric vehicle battery market."
The PEA was prepared by Erudite Strategies 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.

METALLURGY & PRICING
The PEA 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%.

| +48 mesh (jumbo flake) | 23.6 | 96.9 |
| +65 mesh (coarse flake) | 14.6 | 97.1 |
| +80 mesh (large flake) | 8.2 | 97.0 |

| +150 mesh (medium flake) | 15.5 | 97.3 |
| +200 mesh (small flake) | 10.1 | 98.1 |
| -200 mesh (fine flake) | 21.1 | 97.5 |
Pricing Matrix - Flake Size Distribution Grouping and Product Grade
| Product Size | % Distribution | Product Grade (% Carbon) |
| >50 mesh | 23.6 | 96.9 |
| -50 to +80 mesh | 22.7 | 97.1 |

The selling price used in the PEA 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. Prices used are based on current market prices provided by UK-based, commodity price reporting agencies Benchmark Minerals Intelligence and Fastmarkets, who are recognized as leaders in providing independent and unbiased market research, pricing trends and demand and supply analyses for the natural flake graphite market.
No price escalation for graphite sales prices into the future was applied to the PEA model. Current market prices were used and flatlined over the life of mine. No pricing premium for valued-added applications was applied on any sales. Furthermore, no financial or operational calculations and/or scenarios in the PEA 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.
Battery Anode Facility
The PEA's enhanced Phase 2 capacity was determined based on discussions with automotive manufacturers ("OEMs") and our battery anode offtake partners. The Company and the battery anode offtake partners are evaluating construction of a battery anode facility ("BAF"), capable of converting flake graphite concentrate from any qualified mine into spheronized and purified graphite ("SPG") and into coated SPG ("CSPG"). CSPG is the final form of natural graphite required to manufacture lithium-ion batteries required by OEMs. As announced on November 15th, 2021, the Company initiated a technical study to determine the capital and operating costs for our first BAF and is considering several proposed locations.
Based on recent discussions with OEMs and our battery anode offtake partners, the Company expects demand for CSPG to experience significant growth. For example, a single mid-sized OEM's 7-year demand forecast would require NextSource to construct a BAF with a CSPG production capacity of 58,000 tpa. Since it takes 2.2 tonnes of flake graphite to produce 1 tonne of CSPG, the majority of Phase 2 production capacity would be dedicated to supply the BAF for such a single mid-sized OEM.
Molo PHASE 1 Construction and Commissioning Update
On January 11, 2022, the Company announced the Molo Phase 1 processing plant (the "Processing Plant"), which was fully fabricated and constructed at an offshore facility, had successfully passed Factory Acceptance Testing and final verification. The Processing Plant has since been dismantled, packaged and is now ready to be shipped to the mine site.
Due to Madagascar's ongoing COVID-19 travel restrictions, and recent cyclone activity impacting the eastern seaboard of the country, the commencement of earthworks and civil work at the mine site has been delayed and commissioning of the Molo Phase 1 process plant is now targeted for Q3, 2022.
Phase 1 of the Molo Graphite Mine is fully funded and when commissioned, Molo will become one of the few operating graphite mines outside of China.
The Company has not yet made a production decision in respect of Phase 2. The Company expects that it will assess the results of a definitive feasibility study before making a production decision in respect of Phase 2.
