NEWS RELEASE I 10 MARCH 2025
OUTSTANDING GRAPHITE PURIFICATION RESULTS
Testwork Demonstrates Potential Benefits of Using Kasiya Coarse Flake Graphite
for Future Downstream Customers
· Testwork confirms Kasiya coarse flake graphite can be purified to:
o 99.95% using acid purification
o 99.98% using alkaline purification
· Suitable for use in high margin applications including powder
metallurgy, isostatically pressed refractory products, and high-grade expanded
graphite products such as foils or sheets
· Successful purification of Kasiya's coarse flake graphite via two
methods showcases potential for future downstream customers to reduce reagent
consumption and waste generation
Sovereign Metals Limited (ASX:SVM; AIM:SVML; OTCQX: SVMLF) (Sovereign or the
Company) is pleased to announce the results of purification testing of coarse
flake graphite concentrate from the Company's Kasiya Rutile-Graphite Project
(Kasiya or the Project) for applications requiring a higher-grade product,
such as powder metallurgy, isostatically-pressed refractory products and
high-grade expandables (e.g. flame retardants). These applications typically
require less than one percent ash in coarse flake graphite, i.e. a loss of
ignition (LOI) purity of more than 99%.
Sovereign engaged ProGraphite GmbH (ProGraphite) to conduct the testwork using
coarse (>180-micron) flake graphite from Kasiya and to investigate acid and
alkaline purification alternatives under conditions typically used to achieve
the +99% LOI target. Purification of Kasiya coarse flake achieved 99.95% LOI
purity using acid purification and 99.98% LOI purity using alkaline
purification, which is significantly higher than the >99.0% target.
Managing Director and CEO Frank Eagar commented: "These are truly outstanding
results - effectively achieving battery grade purities of +99% and less than
0.05% ash under conditions that typically result in under 1% ash. For our
future customers, this has the potential to significantly reduce reagent
consumption and waste generation in the production of high-purity flake or
targeted high-end applications.
This is yet further confirmation that Kasiya graphite concentrate is a premium
graphite suitable for the anode, refractory, expandables and now also the
high-purity powder metallurgy markets. We are delighted with the significant
commercial optionality it brings to the Kasiya Rutile and Graphite Project."
High-Purity Coarse Flake Graphite
High-quality coarse flake graphite can achieve grades of 97%-98% in minerals
processing. However, specific coarse flake applications require less than 1%
ash content in the flake, i.e. a LOI purity of more than 99%.
To achieve this target, the coarse flake is typically purified using either:
· acid purification, using hydrofluoric (HF) acid as the primary acid
to remove silicates and other impurities; or
· alkaline purification, where HF is replaced with sodium hydroxide
(NaOH), i.e. caustic soda, to remove silicates before being washed and then
acid leached to remove residual metals.
The conditions required to achieve a >99% purity are less aggressive than
those needed to achieve battery grades (>99.95%). ProGraphite targeted the
purification of coarse (>180 microns) Kasiya flake under conditions
typically used to meet the >99% target. The LOI purity and residual
impurities are summarised in Table 1, with all other elements below 1ppm or
below the detection limit.

Al ppm 55.6 3.88
Ba ppm 21 6.45
Ca ppm 18.6 0.98

P ppm 1.85 0.97
Na ppm <1.5 40.8
Ti ppm 15.8 0.56
Zr ppm 6.54 0.74
Testing on Kasiya coarse flake effectively achieved battery-grade purities
(≥99.95%) using a single-stage HF purification and an exceptional 99.98%
purity with alkaline purification under standard conditions that typically
reach a >99% target. HF (a high-cost toxic reagent that requires careful
management) is normally required to remove residual silicates in natural
graphite. However, these results indicate that the saprolite-hosted Kasiya
graphite is amenable to alkaline purification. This will provide downstream
customers with process flexibility.
The results indicate potential for customers to reduce reagents consumption to
produce standard products (>99%) purity, or, subject to market demand,
produce very high-purity coarse flake. Typical uses for high-purity coarse
flake include powder metallurgy, isostatically pressed refractory products,
and high-purity expandables.

All samples within the pit shell were added to the composite resulting in a
sample of 15,766kg.
Samples were processed separately for the eight locations through Sovereign's
Malawi metallurgical laboratory.
The following workflow was used to generate a pre-concentrate graphite feed:
· Wet screen at 2mm to remove oversize
· Dry screen at 1mm to remove oversize
· Wet screen at 600µm
· Wet screen at 45µm to remove -45µm material
· Pass +45µm -600µm (fine sand) fraction over laboratory wet
shaking table to produce a heavy mineral concentrate, light middling and wet
table tailings which is the graphite concentrate.
· The +45µm -600µm (fine sand) graphite concentrate and
<1000µm >600µm screen fraction were combined to provide flotation
feed. The >1000µm fraction was not included.
· Flotation was performed at Maelgwyn in Johannesburg.
· Fine and coarse gravity tailing samples contain approximately
75%-80% of the graphite present in the feed sample. The majority of the
graphite lost is contained in the -45µm fines.

residual rutile and graphite deposits in Malawi.
Geology Deposit type, geological setting and style of mineralisation The rutile deposit type is considered a residual placer formed by the intense
weathering of rutile-rich basement paragneisses and variable enrichment by
eluvial processes.
Rutile occurs in a mostly topographically flat area west of Malawi's capital,
known as the Lilongwe Plain, where a deep tropical weathering profile is
preserved. A typical profile from top to base is generally soil ("SOIL" 0-1m)
ferruginous pedolith ("FERP", 1-4m), mottled zone ("MOTT", 4-7m), pallid
saprolite ("PSAP", 7-9m), saprolite ("SAPL", 9-25m), saprock ("SAPR", 25-35m)
and fresh rock ("FRESH" >35m).
The low-grade graphite mineralisation occurs as multiple bands of graphite
gneisses, hosted within a broader Proterozoic paragneiss package. In the
Kasiya areas specifically, the preserved weathering profile hosts significant
vertical thicknesses from near surface of graphite mineralisation.
