Zinnwald Lithium CEO, Anton du Plessis, said:

 

"Our objective is to deliver a bankable feasibility study, which in turn will
take us closer to delivering a much-needed supply of lithium hydroxide to the
European market. The secular demand growth picture underpinned by ambitious,
government mandated climate change goals together with limited supply response
continues to underpin the robust fundamentals for the sector despite broader
economic headwinds.

 

"To this end, we are very pleased with the continued results from the Project;
not only have we undertaken extensive testwork focused on producing battery
grade lithium hydroxide but also on optimising all steps of the production
process. We are also optimising the plant layout, mine plan and infrastructure
all driving improved Project Economics.

 

"I look forward to providing further updates on our progress as we focus on
ensuring the underlying value of our compelling asset is more fully reflected
in our share price."

 

DETAILS

Zinnwald Lithium has made good progress advancing its 100% owned Zinnwald
Lithium Project in Germany as it looks to become an important supplier of
lithium hydroxide to Europe's fast-growing battery sector.

 

1.    Testwork related to Production Processes

In March 2022, the Company announced the successful completion of testwork
that demonstrated the technical and economic viability of producing lithium
hydroxide. Over the subsequent period, with the objective of strengthening the
Project's economics, the Company has successfully carried out a number of
additional areas of testwork on all stages of the production process, further
details of which are set out below.

 

Mining and Geometallurgy

TheiaX GmbH, a local German company, has completed initial hyperspectral core
scanning tests on both existing drill core from previous drilling campaigns,
and crushed ore samples from the previous pilot tests. The hyperspectral
scanning produced clear quantitative information on Zinnwaldite (Li-mineral),
Muscovite, Clay minerals and Topaz from both the drill core and the crushed
product. In comparison to standard one metre assay intervals, the
hyperspectral imaging produced information on five cm intervals and detected
lower grade inclusions from the core giving a very clear indication that
online hyperspectral imaging could be used for value-based bulk or particle
sorting of crushed ore.

 

In a separate campaign, Metso:Outotec / Tomra tested the amenability of
Zinnwaldite ore for particle sorting. All Zinnwaldite lithologies, ore and
waste, were tested. Different lithologies could easily be distinguished and
hence particle sorting was found to be suitable for Zinnwald ore. Further
testwork will be carried out with a larger representative bulk sample during
Q3 2022.

 

The objective of these testwork campaigns is to reduce ore processing costs by
removing waste and low-grade material from the Mineral Processing circuit
before the expensive grinding, drying and magnetic separation stages, as well
as minimising the quantity of fine material produced as by-product.

 

If successful, this could also lead to an increase in total Mineral Resources.
The current Mineral Resource excludes Ore Type 1 lenses thinner than two
meters due to processing cost per tonne waste rock mined. With better
understanding of the small-scale grade variation and application of sorting
process, it may be possible to lower the Li cut-off grade of Ore Type 1.  In
addition, a considerable amount of lithium at the Project is contained in the
"Greisenised Granite" rock, which could potentially be included in Mineral
Resources. This material can be understood as an alteration halo surrounding
the Ore Type 1 and is estimated at 214 Mt at a Li grade of 1700 ppm. It is
currently not included in the Project's Mineral Resources of 40.4 million
tonnes (35.5 million tonnes measured and indicated plus 4.9 million tonnes
inferred), as set out in the relevant Competent Person's Report in the
Company's admission document published in October 2020.

 

Pyrometallurgy

Calcination (roasting of pre-treated Zinnwaldite concentrate) testwork was
carried out by IBU-tec Advanced Materials AG. The calcination testwork focused
on pre-treatment of the concentrate with different additives, agglomeration
and roasting of the agglomerate. The test targeted the possibility of
utilising cheaper additives and a higher leach rate of lithium and potassium
from calcine. The tests for calcine leaching of the calcined material were
carried out by K-UTEC AG Salt Technologies AG ('K-UTEC').

 

The tests indicated that Flue Gas Desulfurization ('FGD') Gypsum is suitable
for the purpose. FGD Gypsum is readily available and inexpensive and would
represent a cost saving versus using primary gypsum. The tests also showed an
increased lithium recovery rate of 90% (previously 87%) and an increased
potassium recovery rate of 70% (previously 50%) from Zinnwaldite ore compared
with what was demonstrated in the previous NI 43-101 Feasibility Study.

 

Hydrometallurgy

The Company has commissioned K-UTEC to conduct an initial, scoping level study
on upgrading the potassium sulphate ('SOP') and precipitated calcium carbonate
('PCC') by-products of the process.

 

As part of the LiOH test work completed in Q1 2022, the potential to produce
high purity SOP (>99.5%) and industrial grade (>98.5%) PCC has already
been demonstrated. This new study will evaluate the commercial feasibility of
the production of these high purity by-products. These by-product credits
already have a meaningful impact on the operational cost economics of the
Project, but could be even further improved as, for instance, the price of
high purity SOP has historically been up to double that of fertilizer grade
product.

 

2.    Drill Programmes

Zinnwald Lithium Deposit

The Company is ready to start an in-fill drilling programme at the Zinnwald
Lithium Deposit subject to receipt of final permits. The purpose of the
in-fill drilling programme is to study the mining scale variability of the ore
with the view of applying larger scale mining methods. The ultimate aim is to
accommodate greater mining capacity for expanded Li-product output.

 

Zinnwald Lithium has engaged SRK Consulting (UK) Ltd to provide competent
person support for the drill campaign and geometallurgy.

 

Permitting of the drilling campaign is at an advanced stage with the relevant
authorities and favourable permissions have already been received from several
landowners.

 

The Company has signed a contract with GEOPS Bolkan Drilling Services Ltd,
which has committed to have drill rigs available when drilling is permitted to
begin. The Company has also leased and taken occupancy of new warehouse space
in Freiberg that will be used for core storage and core logging and processing
of new drill core when the drill programme commences. The facility is being
outfitted with the latest safe and environmentally friendly equipment.

 

Falkenhain Exploration Licence Area

The Company's Falkenhain exploration licence is located 7km north from the
core Zinnwald Licence.  The licence area was historically extensively
explored for occurrences of tin and tungsten with drilling undertaken most
recently from 1963 to 1990. The Company has performed a detailed review of the
historic data including assaying samples of the surviving core from these
campaigns. The outcome from this work has identified the potential for a
lithium resource. The Company has therefore designed an exploration drill
campaign of ten diamond drill holes to test the historic drill data and better
determine the resource potential of the licence.

 

3.    Access to Legacy Mining Infrastructure

In March 2022, the Company was granted access to portions of the existing
mining infrastructure in the vicinity of the Project for inspection purposes.
This infrastructure includes a 4km drainage tunnel, and disused ventilation
and access shafts, which potentially could be used as part of its
operations.  The infrastructure was found to be in excellent condition and
easily accessible. The Company continues to develop its plans for the possible
utilisation of this infrastructure to beneficially impact the Project and is
also in discussion with the owners of the assets for access and usage.

 

4.    Other Operational Matters

ESG

In line with its progressive ESG policy, the Company is committed to
delivering benefits to the local community. The Company has held several
meetings with different stakeholders regarding its plans for the future.
Members of the management team have met with local and provincial authorities
to keep them updated regarding progress and plans for the Project.

 

As part of the public engagement effort, an encouraging consultation and
information meeting was held in the village of Zinnwald in March 2022 to
explain the drill programme and plans to develop the Project. In order to
assist in keeping the public and the authorities informed about the Project, a
local project office will be established for the duration of the drilling
campaign.

 

Occupational Health and Safety ('OHS')

As the team expands and new physical work stages advance, the OHS aspects have
been reconsidered. The Company targets zero incidents through training,
selection of work methods and continuous auditing.

 

Horizon Europe

In May 2022, the Company joined the "Exploration Information Systems" project,
part of the EU funded Horizon Europe Research and Innovation scheme. The
research project focuses on developing new exploration techniques that are
based on large datasets, artificial intelligence and deep learning methods to
identify new sources of raw materials. Precise techniques that can take
several factors into consideration to determine prospectivity of deposits, aim
to lead to more effective exploration decision making and consequently reduced
project development costs.

 

Zinnwald Lithium believes that such projects are crucial in securing the
necessary materials for future generations and is proud to contribute to this
effort by providing a case study site in Germany.

 

Management and Staffing in Germany

Dr Armin Mueller has stepped down from his role as Managing Director of
Zinnwald Lithium's local German subsidiary, Deutsche Lithium GmbH, in order to
pursue other opportunities. He has been succeeded by Dr Torsten Bachmann. Dr
Bachmann is Dipl.-Ing. of Environmental Technology and has a PhD in Chemistry.
He has over 15 years' experience in science and industry in the area of
photovoltaics and inorganic chemistry and long-term experience in the
management of national research projects. He was team leader in the "Lithium
Zinnwald Project" from 2011 to 2015 and since 2017 has been responsible for
"Chemical Processing" aspects of the Project.

 

In addition, the Company has further strengthened the team in Germany, adding
skills in several key disciplines including geology, mining, and logistics.

 

5.    Outlook

Looking forward, the Company's near-term priorities are the commencement of
the in-fill and exploration drill campaigns. In addition, it is focused on
enhancing the Project technically and economically through increasing the
production potential, re-orienting it towards lithium hydroxide and seeking
optimisation opportunities across all key areas.  The Company will provide
investors with greater clarity on revised project parameters in the form of a
Preliminary Economic Assessment as soon as it can.

 

As at the date of this announcement, the Company has funds on hand of €6.1
million.
