On behalf of the board, I extend our gratitude to our team, partners, and
stakeholders who have been instrumental in reaching this milestone. We are
excited about the future and look forward to continuing our journey towards
excellence in lithium refining."


TVL Train 1 - Crystalliser technology package award - JordProxa


Train 1 utilises the standard causticisation process for the production of
lithium hydroxide monohydrate. The flowsheet comprises conversion of various
feedstocks if required, impurity removal, evaporation, glauber's salt
crystallisation, anhydrous sodium sulphate crystallisation and multi-stage
lithium hydroxide crystallisation followed by product handling and bagging.


The Class 4 study completed by Wave International as the lead process designer
defined the crystallisation circuit parameters. JordProxa have considered
these parameters and completed metallurgical testwork, producing high purity
Lithium hydroxide Monohydrate.


On this basis, a crystallisation process island has been proposed which


·    PLS evaporation;

·    Glauber's salt crystalliser;

·    Anhydrous sodium sulphate crystalliser; and

·    Multi-stage lithium hydroxide crystallisers.


The process island approach is a key aspect of the overall plant design,
simplifying the procurement activities and reducing interface risk. This
approach represents an evolution from what has been achieved by the recent
Australian plants and incorporates significant learnings from those projects.
This next generation of crystalliser design will provide for significant
technical de-risking of TVL's project.


Based on the preferred vendor status, TVL Wave International and JordProxa
will work together towards a finalised commercial contract including:


·    basic engineering and design (including modularisation);

·    process guarantees;

·    detailed manufacturing schedule including long lead milestones; and

·    further optimisation testwork and supply of pilot scale equipment.


The next phase of works planned is completion of basic engineering design,
which is a critical activity to underpin Front End Engineering Design (FEED)
for the balance of the plant and infrastructure.


Design for a pilot plant is also underway, which will produce sales and
marketing samples to progress product qualification.


TVL Train 2 - Electrochemical cell package award - Eurodia Industrie SAS


Train 2 utilises an electrochemical process to produce lithium hydroxide from
lithium sulphate or lithium carbonate. The front half of the flowsheet is
similar to the conventional process, with some additional impurity removal
stages ahead of the electrochemical cells. The electrochemical cells use
electricity (instead of a chemical reagent) to separate lithium sulphate into
sulphuric acid and lithium hydroxide, which can then be crystallised into
lithium hydroxide monohydrate. A similar, but simplified, crystallisation
circuit is used for this final step.

This approach is suited to a facility which has access to abundant, cheap
renewable energy and has the ESG benefits of:

·    removing the need for sodium hydroxide as a reagent (which is
currently in high demand); and

·    removing anhydrous sodium sulphate as a bi-product

The sulphuric acid bi-product can either be concentrated and used to digest
alternative feedstocks (or used in other low-specification applications) or
converted to gypsum and used in local industry. It is noted that gypsum is
currently imported at the adjacent PD Ports.

The separation of salts via electrochemical cells is a proven technology in
water treatment, with a number of large-scale plants operating throughout

The Class 4 study by Wave International as the lead process designer defined
the electrochemical  circuit parameters. Metallurgical testwork was completed
in parallel at two specialist laboratories, including a membrane screening
program in which Eurodia membranes were compared to others by an independent
laboratory. This testwork independently showed the Eurodia technology to have
superior lithium recovery and sulphuric acid quality and was a key factor in
the technology selection.

Based on the preferred vendor status, TVL Wave International and Eurodia will
work together towards a finalised commercial contract including:


·    Basic engineering and design;

·    Process guarantees;

·    Detailed manufacturing schedule including long lead milestones; and

·    Further optimisation testwork and supply of pilot scale cells.


TVL and Wave International are jointly finalising the technology development
framework for Train 2, with the next stage being the completion of a pilot
scale plant development. The supply of a pilot scale cell and progression of
basic engineering design will be the next stages of engagement with Eurodia.
