Morella Corp Ltd (ALTAF)

Direct Extraction Study (DLE)
During the Quarter the Company received an interim progress report from Recion Technologies
(“Recion”) which provided positive early-stage indications of successful lithium concentration using
Recion’s ion exchange media (Media) process and FLV brine.
The brine sample used for testing was obtained from (417,213mE; 4,197,266mN; 1438mRL) near
surface (from 4.26m) of the playa at FLV and was expected to be highly diluted from surface water,
however the testing process focussed on lithium extraction from the brine type or signature of the
brine. As part of the next phase of DLE testing Morella will provide brine samples from reservoirs
identified in the Passive Seismic and MT surveys completed earlier in 2022. (Refer ASX announcement
Geophysical Exploration Update for Fish Lake Valley Lithium Project released on 22 February 2022)
The report has identified that two hours of absorption is sufficient to extract lithium from the brine
with extraction efficiency up to 95% using an absorption column configuration. Absorption column
configuration has been used in water treatment operations and is known to be scalable using
standard/commercially available equipment.
Extended testing saw high lithium recoveries, resulting in lithium concentration levels over 600%.
Kinetics Test
Morella provided a 20 litre brine sample to Recion in June 2022, initial testing was conducted at
benchtop scale, focusing on understanding how Recion’s Media process performed with the FLV brine.
