E3 Lithium Completes Initial Field Pilot Plant Tests and Shares Results Against KPIs

E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company,” Alberta’s leading lithium developer and extraction technology innovator, is pleased to report it has completed the series of three optimized tests at its Direct Lithium Extraction (DLE) Field Pilot Plant with results surpassing Key Performance Indicators (KPIs). The pilot continues to operate with the selected optimized test, outlined below, to confirm the results, while also producing lithium concentrate for further lithium production testing.

Initial Results

As shown in the table below, all three tests have exceeded the KPIs.

Success Criteria	Key Performance Indicator (KPI)	Description	Test 1	Test 2	Test 3
Lithium recovery	≥ 80%	Mass of lithium recovered from the mass of lithium in the feed	95%	94%	83%
Lithium grade in the lithium product stream	≥ 25%	Concentration of lithium relative to other impurities (Na+K+Ca+Mg+Mn+Sr+B)	91.5%	80.1%	61.8%
	≥ 600 mg/L	Concentration of lithium in the lithium product stream	969.8 mg/L*	909.0 mg/L*	786.1 mg/L
Flow rate ratio	≥ 3	Brine flow rate divided by the system volumetric capacity	6.7	9.0	4.4
* Verification testing was completed on all preliminary data as a matter of course. The updated data outlines minor changes in the lithium concentration in the product stream than previously reported.

The differences between each test included changes in the operating conditions to optimize the cycle time (the amount of time the sorbent was exposed to the brine), flow rate ratio and the duration of each cycle.
