Metallurgical Results from the
Olserum REE Project
European Green Transition (AIM:
EGT), a company developing green economy assets in Europe which
aims to capitalise on the opportunity created by the green energy
transition, is pleased to announce its
first metallurgical test work results from the Olserum Rare Earth Elements ("REE") project in south
Sweden.
Highlights
· Test work confirms that the
mineralisation style at Olserum is capable of producing a REE-rich
concentrate from simple magnetic separation followed by standard
flotation.
· Following 20 flotation tests,
a flowsheet to produce separate REE, apatite and magnetite
concentrates has been devised using conventional and well-proven
beneficiation techniques. A bulk REE-apatite concentrate containing
the minerals monazite, xenotime and apatite was produced with high
recoveries of 84.4-92.6% for light rare earth elements ("LREE") and
80.9-90.7% for heavy rare earth elements ("HREE"). The bulk
REE-apatite concentrate had grades between 10.5% and 12.6% total
rare earth elements ("TREE").
· This was increased to
30-40.11% total rare earth oxides ("TREO") after high gradient
magnetic separation ("HGMS") on the bulk concentrate with initial
recoveries of between 55.3-64% for LREE and 53.8-72.5% for HREE
respectively, representing a mass pull of only
1.03-2.04%.
· The Directors
believe that these results, in conjunction with EGT's fully
permitted low-cost drill programme scheduled for H2-2024, will
support the Company in seeking to monetise the Olserum project by
attracting a partner to fund a larger scale programme.
Aiden Lavelle, Chief Executive
Officer of European Green Transition, said:
"This metallurgical
test work on a 135kg sample of typical mineralisation from the
Olserum REE Project indicates that the target REE phosphate minerals can be concentrated
into a high-grade concentrate with a significant proportion of
high-value and critical heavy rare earths. The grade of the final
concentrate exceeded my expectations, and the mineralogy of the
final concentrate was dominated by the target minerals with 40.25%
being monazite and 24.25% being xenotime which is very favourable.
It demonstrates that a low volume high-grade concentrate can be
produced at Olserum and can potentially be processed at a
3rd party's facility, which is significantly more
cost effective than developing a bespoke processing
facility. Test work such as this is crucial
to derisk further investment and demonstrate to
potential partners that the mineralisation style can be processed
using conventional and relatively simple processing
techniques.
"We believe
these results further strengthen the Olserum REE
project and make it an attractive European based
proposition, as a number of companies
internationally are looking to increase REE production from
monazite feedstocks and are actively seeking feedstock for new and
proposed plants. We are now focused on our fully permitted
low-cost drill programme for Olserum in H2 2024, which we believe
could confirm a district scale REE system with further project
upside, supporting our intention to attract a partner to fund a
larger scale programme."
Test
Work Results
The results of laboratory test work on a
composite sample of historic core from the historic (2013) Olserum
REE resource confirm the potential for the Olserum mineralisation
to be processed using relatively straightforward and simple
beneficiation techniques. The work improves upon the earlier
testing in 2013 which was paid for by the European Commission's
EURARE research project. The new test work was carried out at the
GTK laboratory in Finland and overseen by the same expert who was
involved in the previous work. Recent fieldwork including rock chip
and channel sampling has identified the same style of
mineralisation across the developing district-scale REE system and
this test work gives confidence that the mineralisation style is
amenable to producing a low volume concentrate with very good
recoveries.
Flow Sheet And
Test Work
A composite sample weighing approximately 135Kg
was first crushed to -1.5 mm and ground to a suitable size for
mineral liberation in a lab rod mill. A grinding test was conducted
for determination of the relationship between the grinding size and
the grinding time. Mineralogical analysis showed that monazite and
xenotime are present at higher contents in the -75μm fraction
compared to the -250μm to +75μm fraction. The flow sheet was
based on 80% passing around 100μm.
Wet low intensity magnetic separation ("WLIMS")
was then conducted to recover magnetite prior to flotation. The
non-magnetic product from the WLIMS was reported to bulk REE and
apatite flotation after dewatering by filtration. A total of 20
WLIMS and bulk flotation tests were completed to test different
parameters and establish the optimal flotation
conditions.
The bulk REE and apatite concentrate was
further processed to separate the REE-phosphates from the apatite
by trialling various methods including HGMS, gravity concentration
with a shaking table and further flotation. The separation of the
bulk REE concentrate into a REE concentrate and apatite concentrate
was a new development from previous test work and it was found that
the HGMS was somewhat successful in upgrading the REE grade of the
concentrate albeit with some REE losses to the apatite
concentrate.

Results
A high purity
magnetite concentrate can be produced using WLIMS prior to
flotation. The magnetite concentrates obtained from the WLIMS tests
had grades of between Fe 59-64% and 80-90% magnetite with very low
recoveries of REE and P, typically 0.12%-0.18
P2O5. The vanadium content is c.0.15%
V2O5. Magnetite represents 3.76%
of the sample according to the MLA (mineral liberation
analysis).
The best results
achieved in the set of flotation tests had recoveries ranging
between 84.4% and 92.6% for light rare earth elements (Ce as a
proxy for LREE) and 80.9% and 90.7% for heavy rare earth elements
(Y as a proxy for HREE). The bulk REE-apatite concentrate generated
by these tests had grades estimated between 10.5% and 12.6%
TREE.
Following HGMS of
the bulk REE-apatite concentrate, a REE concentrate with grades up
to 30-40.11% TREO was produced at initial recoveries of between
55.3-64% for LREE and 53.8-72.5% for HREE respectively,
representing a mass pull of only 1.03-2.04%. The apatite
concentrate grade was 33% P2O5 at a recovery
of 57.3% representing a mass pull of 2.8%.
The final upgraded concentrate produced after
the HGMS had the following grades:

Sample Information, Quality
Assurance / Quality Control
The composite sample weighing 135kg was
obtained from 149m of quarter core which was cut from six historic
intersections across four drill holes within the historic 2013
resource at Olserum. The holes which were sampled were OLO514,
OLO513, OLO516 and OLR12004. The core was cut to ¼ core samples
at ALS Minerals in Mala prior to bagging
into 6 separate samples for dispatch to the GTK Circular Economy
Solutions Laboratory in Outokumpu, Finland. The samples were
crushed, blended and milled at GTK to provide a further set of 20
sub samples for bench-scale flotation and WLIMS tests.
The head sample was analysed by XRF and ICP-MS,
respectively by CRS Laboratory in Finland and MSA LABS in Canada.
The head grade analysis by ICP-MS was 7,045 ppm TREE, equivalent to
0.849% TREO. This was very close to the expected length-weighted
grade of 0.876% TREO based on the historic assay intervals. The
head grade and flotation test analyses by XRF appear to
under-report the REEs compared to ICP-MS analyses which are deemed
more accurate. Recoveries for individual flotation tests were based
on XRF analysis of Ce as a proxy for LREE and Y as a proxy for
HREE. High levels of La in the sample caused interference in the
GTK XRF instrument and La was not fully analysed in the GTK assays
but can be estimated based on a consistent correlation to Ce values
in other assays. The final concentrate was analysed at MSA labs in
Canada with all REE elements reported separately.
MSA Labs included blanks and
standards within the sample stream to monitor QAQC (quality
assurance and quality control). The difference in
recoveries between LREE and HREE in this announcement reflects the
distribution of the REE elements between the minerals monazite and
xenotime with monazite usually hosting LREE and xenotime hosting
HREE. The chief expert supervising the work at GTK was Jason
Yang (Yang Xiao Sheng).
