Tantalex Lithium Resources Corp. reported that it has filed its NI 43-101 Preliminary Economic Assessment (PEA) Report for the Manono Lithium Tailings Project, Manono, Democratic Republic of Congo, with an effective date of October 6th, 2023 (the Mineral Resource Report). As highlighted on the news release of October 6, 2023, the results of the PEA are compelling, and the Company Board has recommended the Project to proceed to a Feasibility Study.

Key PEA Highlights: Excellent project economics and financial returns: Robust pre-tax NPV10% of approximately USD 764 million and 87.4% IRR on a nominal basis, and a pre-tax NPV 10% of approximately USD 638 million and 82.3% IRR on a real basis. Rapid payback of 1 year after first production using a Life of Mine spodumene concentrate price of USD 2,800/t SC5.5 (FOB, Africa) as forecast by Fastmarkets, an internationally recognized price reporting agency. Project Capital Cost Estimate (CAPEX) of USD 147,7 million including contingencies, Life-of-Mine (LOM) of 6 years with an estimated annual production of 112,000 t of spodumene concentrate.

Low risk plant operation and tailings reclamation: Ready to use tailings dump resources to feed beneficiation plant with minimum cost of mining, crushing, grinding, and processing. Process plant nameplate capacity is 1.26Mtpa of run-of-mine (ROM) ore based on robust flowsheet using learnings from other lithium producers. A number of opportunities have been identified to improve capital and operating costs and plant capacity.

The exploration program is being finalized with a focus on increasing indicated resources and extending life of project. The PEA was prepared by Sedgman Novopro of Montreal, Canada with Mineral Resource and Mining contributions from MSA Group in accordance with National instrument 43-101, Standards of Disclosure for Mineral Projects (NI 43-101).
