Pre-Construction Locked-Cycle Testwork Completed

Detailed Engineering Design Independent Testwork Confirms Efficiency of EcoGraf(TM) Process

HIGHLIGHTS

- Independent locked-cycle program, managed by GR Engineering, to provide data for detailed engineering design of EcoGraf(TM) HFfree Battery Anode Material Facility in Western Australia is complete and provides the information to complete equipment sizing and selection

- EcoGraf(TM) product carbon purities achieved 99.97% for tested feedstock confirming the effectiveness of the proprietary EcoGraf(TM) HFfree purification process

- Results indicate further opportunity to reduce reagent consumption in the EcoGraf(TM) process and lower production costs

EcoGraf Limited ("EcoGraf" or the "Company") (ASX: EGR; FSE: FMK; OTCQX: ECGFF) is pleased to report that pre-construction locked-cycle testing has been completed, validating the EcoGraf(TM) HFfree purification process, exceeding carbon purity targets, providing the opportunity to reduce production costs and generating data for detailed engineering design works.

The pilot testing was commissioned by GR Engineering Services Limited ("GR Engineering"), on behalf of EcoGraf, to provide data for detailed engineering design works as part of the pre-construction program for the Company's new EcoGraf(TM) HFfree Battery Anode Material Facility in Western Australia.

A total of six cycles were completed, processing spherical graphite through the multi-stage EcoGraf(TM) HFfree purification flowsheet to simulate operational conditions and obtain final data to undertake detailed engineering for construction of the new Western Australian facility. Excellent results were obtained from filtrate recycling supporting reduced feed water requirements while maintaining impurity levels below customers specifications.
