Maiden Mixed Rare Earth Carbonate with
Very High Dysprosium and Terbium Content
Engage with this announcement on our interactive Investor Hub
ANSTO has produced first mixed rare earth carbonate (MREC) sample product
from Deep Leads deposit in northern Tasmania
Dysprosium and terbium (DyTb) content is 2.8 to 4.7 times higher than peer
MRECs
Calculated basket price is up to 51% higher than peer MRECs
On behalf of ABx Group Limited (ASX: ABX) (ABx or the Company), the Australian Nuclear
Science and Technology Organisation (ANSTO) has produced the first mixed rare earth
carbonate (MREC) sample from the Deep Leads resource in northern Tasmania (Figure 2).
The ABx MREC contains 4.0% dysprosium (Dy) and 0.7% terbium (Tb) as a percentage of total
rare earth oxides (TREO), more than twice that of any other peer MREC (Table 1).
Furthermore, the ABx MREC also contains the highest amounts of other valuable heavy rare
earths and very low impurities, including aluminium, uranium and thorium.
The high proportions of these high value rare earths means that the ABx MREC basket price
is 17% to 51% higher than all peer MRECs (Figure 1).

Figure 2: MREC produced from ABx Deep Leads deposit in northern Tasmania
The production of MREC is a major milestone for ABx as it represents the saleable product
used in downstream refining to produce separated rare earth oxides, rare earth metals and
magnets essential for electric vehicle motors, wind turbines, robots and guidance systems.
ABx Group Managing Director and CEO Mark Cooksey said:
“This is one of the most significant achievements of our rare earths project and we are simply
delighted with this result, especially since it is our first MREC product and there is significant scope
for optimisation. We’ve been eagerly anticipating confirmation of this MREC product, which is
simply the best we know of from any ionic rare earth resource outside of China. Combined with
the resource size, grade and ideal location near existing infrastructure, this means that the Deep
Leads project is a highly compelling opportunity. We can’t wait to share this result with our
prospective customers and receive their feedback. The ABx MREC is likely to be particularly sought
after by customers seeking high DyTb and low uranium and thorium.”
Strategic Importance of MREC Production
Producing a high-purity MREC from a bulk sample represents a critical milestone for ABx in
the development of the Deep Leads project. Existing and prospective rare earth refineries
are seeking high quality MRECs produced at low cost. MRECs with high proportions of Dy
and Tb are in particular demand, because these elements have the most acute supply risk.1
ABx has excellent prospects of meeting these requirements because:
1. Achieving high extractions at ambient temperatures and pressures with minimal acid
in a short time is likely to lead to lower cost and lower impurities in the MREC product.
For most clay-hosted rare earth deposits globally, minimal rare earth extraction is
achieved using these process conditions;
2. The ABx MREC has a significantly higher proportion of Dy and Tb compared to peers.

Magnet rare earth prices remain high, with Benchmark2
reporting Dy oxide (DDP China) at
over US$200/kg and Tb oxide (DDP China) at over US$900/kg. Furthermore, CIF Europe prices
for Dy and Tb are over three times higher than Chinese domestic prices, illustrating the
potential premium for non-China sources of rare earths.
ABx has already executed a Memorandum of Understanding with Ucore Rare Metals Inc.
(TSXV: UCU) (OTCQX: UURAF)3
, which is focussed on rare-earth processing facilities in North
America, and ABx is also in discussions with additional potential offtake partners.
Next Steps
The ABx MREC composition and samples of the MREC product will be shared with
prospective customers and offtake partners for evaluation. ABx expects discussions and
negotiations to deepen based on these results.
For the next stage of project development, ANSTO is conducting column leach tests on a bulk
sample from the Deep Leads deposits. Preliminary results are expected in December.
Bulk Sample Material
The source of the material for the MREC sample is a 100 kg bulk sample from trial pit DLP002
from the Deep Leads resource (Figure 4).4
Mixed Rare Earth Carbonate (MREC) Production
This MREC was produced using the standard three-step process for ionic rare earths:
leaching, impurity removal and precipitation. Firstly, 50 kg of the bulk sample was dried at
100 °C, ground to below <600 micron and leached in 150 kg of 0.3M ammonium sulfate
(25wt% solids loading) at pH 4.5 for 30 minutes. Ammonium bicarbonate was added to raise
the pH of the leached solution to 6.2, where it was held for 30 minutes, to remove impurities
such as aluminium. Finally, additional ammonium bicarbonate was added to raise the pH to
7.4, where it was held for 2 hours to precipitate 72 g of MREC product.
Preliminary results from ANSTO indicate that the leaching and impurity removal
performance were similar to those previously reported in leaching5
and impurity removal6,7
tests.
Peer Identification
Ionic rare earths are defined here as those that can be leached from a deposit under the
conditions listed in Table 2. This is commercially significant because these are the standard
conditions under which MRECs have been commercially produced in China for many years.

The peers considered here are those that meet the following criteria:
1. Publicly reported leaching tests indicated that the resource contains a significant
proportion of ionic rare earths, i.e. numerous leach tests achieving more than 50%
rare earth extraction under the conditions listed in Table 2;
2. An MREC sample has been produced, and the results publicly reported, by leaching
under conditions listed in Table 2,8
followed by impurity removal and MREC
precipitation, both by raising the pH, with no other beneficiation or processing steps;
3. Deposit is not in China, Myanmar or Laos
The peer MRECs are listed in Table 3, along with the conditions under which each MREC was
produced.
Peer Comparison
MRECs can contain a variable level of moisture and hydration, which is removed when the
MREC is calcined9
to create a mixed rare earth oxide (MREO). It is more appropriate to
compare the compositions of MREOs than MRECs, to eliminate the confounding effects of
moisture and hydration. For this peer comparison, the anticipated MREO composition of
each MREC has been calculated by normalising the sum of TREO + impurity oxides to 100%.
The compositions of each MREO are listed in Table 4, which also includes the Chinese
Standard for mixed rare earth oxides produced from ionic rare earth deposits.10
Most
customers are likely to have their own specifications.
All MRECs assessed here meet the China Standard of minimum 93.4% TREO and the
maximums for specified impurities, and their uranium and thorium contents are low. The
ABx MREC has the lowest aluminium content, which is an impurity often of particular concern
to customers.
The relative amount of each rare earth in each MREC are summarised in Table 1 and Figure
3. Crucially, the ABx MREC contains 2.8 to 4.7 times the proportion of DyTb compared to any
other MREC. The ABx MREC also has the highest proportion of other valuable rare earths.
The relative amount of each rare earth dictates the basket price of the MREC, as shown in
Table 6 and Figure 3. These have been calculated based on the compositions in Table 4 and
the REO prices listed in Table 5.11
The ABx basket price is US$43/kg, 17-51% higher than the
other MRECs. This is primarily due to the contribution of Dy and Tb.
8
MRECs produced by heap or in-situ leaching are included even though this takes much longer than 30 minutes,
provided that separate leach tests were conducted using the conditions listed in Table 2.

Relationship
between
mineralisation
widths &
intercept
lengths
• These relationships are particularly important.
• If the geometry of the mineralisation with respect to the drill hole angle is
known, its nature should be reported.
• If it is not known and only the down hole lengths are reported, there should be
a clear statement to this effect (eg ‘down hole length, true width not known’).
• Vertical bulk pit sampling is
appropriate for the horizontal
layers of REE mineralisation
Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts
should be included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar locations and
appropriate sectional views.
• See report
Balanced
reporting
• Where comprehensive reporting of all Exploration Results is not practicable,
representative reporting of both low and high grades and/or widths should
be practiced to avoid misleading reporting of Exploration Results.
• All data to date is reported in
this report
Other
substantive
exploration
data
• Other exploration data, if meaningful and material, should be reported
including (but not limited to): geological observations; geophysical survey
results; geochemical survey results; bulk samples – size and method of
treatment; metallurgical test results; bulk density, groundwater,
geotechnical and rock characteristics; potential deleterious or
contaminating substances.
• All data to date is reported in
this report
Further
work
• The nature and scale of planned further work (eg tests for lateral extensions
or depth extensions or large-scale step-out drilling).
• Diagrams clearly highlighting the areas of possible extensions, including the
main geological interpretations and future drilling areas, provided this
information is not commercially sensitive.
• ANSTO labs are engaged to
undertake the processing on
the 100kg sample to produce a
mixed rare earth carbonate
(MREC)
