NextSource Materials Inc. (TSX:NEXT)(OTCQB:NSRCF) ("NextSource" or "the Company") announces an update on the commissioning process at its Molo Graphite Mine ("Molo mine") in southern Madagascar

Since announcing first graphite production in June 2023, the Company has progressed methodically through debottlenecking and optimization activities to achieve the plant nameplate capacity of 17,000 tonnes per annum of SuperFlake® graphite concentrate.

During this ramp-up process, the Company further identified and is rectifying underperforming equipment in the screening circuit. These constraints have delayed the point at which NextSource expects to reach plant nameplate capacity.

Installation of replacement equipment is expected to be complete in April and ramp-up projected to continue until June, with the aim of achieving nameplate capacity in July. As a result of the revised schedule, the Company expects the first commercial shipment and sale of SuperFlake® concentrate under offtake agreements to occur in June.

Notwithstanding a slower than expected commissioning process, the Company has produced SuperFlake® concentrate with a carbon (C) content of over 95% and concentrate is being stockpiled at the mine and at a third-party warehouse facility at the Port of Tulear for shipment as qualifying material for prospective customers.

To date, the Company has completed the shipment of almost 60 tonnes of qualifying material to our Battery Anode Facility (BAF) Technology Partner for testing and conversion into coated, spheronized, purified graphite ("CSPG").

Molo Mine Expansion Feasibility Study Complete

On December 12, 2023, the Company announced the results of the "Molo Graphite Mine Expansion NI 43-101 Technical Feasibility Study Report 2023 (the "Feasibility Study") that proposed an expansion of the Molo Mine up to a production capacity of 150,000 tpa of SuperFlake® graphite concentrate.

The Feasibility Study, prepared by Erudite Strategies (Pty) Ltd., has been filed under the Company's profile on SEDAR at www.sedar.com, and also available for download on NextSource's website at https://www.nextsourcematerials.com

Readers should refer to the Feasibility Study for details and assumptions relating to the Molo Mine mineral resource and reserve estimates and data verification procedures.

The Company has initiated the environmental permitting process for the expansion of the Molo mine. However, the decision to commence the construction of phase 2 will only be taken once the current initiatives to secure both a binding offtake agreement and sufficient funding for construction costs and working capital are satisfactorily concluded .
