This new design substantially reduces land area usage of the Project by approximately 80% (see Figure 1) and results in no chemical process tailing dams being required at Norra Karr. The combination of the above, results in a single waste stream at the Norra Karr site consisting of the mineral aegirine which can be dry stacked in a lined impoundment together with waste rock from mining, eliminating the need for a wet tailings storage facility. The rare earth, zirconium and niobium bearing concentrate will be transported to a dedicated off-site location for chemical processing and further recovery.
In the PEA following physical separation resulting material streams either are shipped as products or as concentrates for further processing at other locations and a single waste stream to be stored at the Norra Karr site. The Norra Karr site will only include mining and comminution methods consisting of crushing, milling and magnetic separation, eliminating all chemical processing from Norra Karr and associated waste vs the 2015 PFS study. Introducing a revised Project flowsheet to minimize the environmental footprint at the Norra Karr site: The PEA also identifies future opportunities to valorize the residual mined material which could potentially result in all mineralized material mined to be treated as potential commercial products. In the PEA more than 50% of total mined material is planned to be sold as products compared with previously less than 1% in the 2015 PFS.
Significant increase in resource utilization by proposing recovery of nepheline syenite (NS) industrial mineral, zirconium oxide (Zr) and niobium oxide (Nb) products in addition to the rare earth oxide (“REO”) products. Main PEA Highlights (In comparison to the 2015 PFS) (“SRK”) and all figures in the PEA are US dollars unless otherwise specified.Īs previously announced, the Company commissioned SRK to re-evaluate the Project at PEA level with the objective to improve resource utilization, project sustainability and substantially minimize environmental footprint of the Project compared to the design in the pre-feasibility study which was released in 2015 1 (the “2015 PFS”) and formed the basis for the current mining lease permitting process. (“ Leading Edge Materials” or the “ Company”) ( TSXV: LEM) ( Nasdaq First North: LEMSE) ( OTCQB: LEMIF) is pleased to announce the results of a Preliminary Economic Assessment study ("PEA" or the “Report”) for the development of its 100%-owned Norra Karr REE project located in Sweden (“Norra Karr” or the “Project”).
