SPECTACULAR DRILL RESULTS CONFIRM VERY HIGH LITHIUM ASSAY RESULTS GREATER THAN 4% Li2O AT
CARRIERE DE L’ESTE PROSPECT
Highlights
o Results from the final 2 of 6 reconnaissance drill holes at the Carriere de l’Este prospect confirms further widespread, high-grade spodumene lithium mineralisation including 68.0m* @ 2.0% Li2O & 858ppm Sn in hole CD18DD006.
o 90 samples returned values greater than 2% including 5 individual samples grading greater than 4% Li2O with the highest value being from hole CD18DD006 from 181 to 182 metres downhole grading 4.65% Li2O.
o The latest drill holes demonstrate grade continuity both down-dip and along strike at Carriere de l’Este with both holes starting in soil cover again confirming “blind” pegmatite in previously unknown strike extents of the main deposit.
o Results confirm continuity of the Carriere de l’Este pegmatite under alluvial cover and shallow dipping high grade intersections present within wider zones of well mineralised spodumene pegmatite.
o High grade mineralisation from Carriere de l’Este has the potential for future blending with existing Roche Dure mineralisation to possibly reduce payback periods.
o The Definitive Feasibility Study continues to be advanced. AVZ’s Managing Director Mr Nigel Ferguson commented: “These last 2 holes drilled at Carriere de l’Este are of the same lithium grade tenor and intersection widths as those reported on previously – (19th February 2019). Both holes 5 and 6 have drilled through high grade zones averaging over 2% Li2O, mineralisation which was also seen on holes spaced 200 metres along strike. Hole 5 for example generated 56 by 1 metre assays greater than 2% Li2O with a maximum value in one sample of 3.97% from 166 to 167 metres deep. Hole 6 was comparable with 97 samples returning values greater than 2% including 5 individual samples grading greater than 4% Li2O which equates to each of the 5 samples containing in excess of 50% spodumene. The highest value from hole 6 was from 181 to 182 metres downhole and reported 4.65% Li2O (Figures 1 and 2).
Carriere de l’Este is unlike Roche Dure in that it has higher grade zones within well mineralised pegmatite suggesting a more classical zonation model for this large pegmatite. Depending on future drilling, this may open up possibilities for high grade blending with Roche Dure mineralisation to shorten pay back periods and is definitely worth considering as we move through the mining study phase currently underway.”

JORC TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (e.g. cut channels, random chips, or specific
specialised industry standard measurement tools appropriate to the minerals
under investigation, such as down hole gamma sondes, or handheld XRF
instruments, etc). These examples should not be taken as limiting the broad
meaning of sampling.
• Include reference to measures taken to ensure sample representivity and the
appropriate calibration of any measurement tools or systems used.
• Aspects of the determination of mineralisation that are Material to the Public
Report.
• In cases where ‘industry standard’ work has been done this would be relatively
simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from
which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such as where there is coarse gold
that has inherent sampling problems. Unusual commodities or mineralisation
types (e.g. submarine nodules) may warrant disclosure of detailed information.
• Diamond drilling, producing drill core has been utilised to sample the
pegmatite below ground surface. This method is recognised as providing the
highest quality information and samples of the unexposed geology.
• Supplementing the drilling data, surface samples were collected from
outcrops, utilising channel sampling from trenches and point-source sampling
of scattered outcrops.
• Based on available data, there is nothing to indicate that drilling and sampling
practices were not to normal industry standards at the time within the Manono
licence PR13359. The pegmatite has been sampled from the hanging wall
contact continuously through to the footwall contact. In addition, the host-
rocks extending 2 m from the contacts have also been sampled.
• Diamond drilling has been used to obtain core samples which have then been
cut longitudinally. Intervals submitted for assay have been determined
according to geological boundaries. Samples were taken at 1 m intervals.
• The submitted half-core samples typically had a mass of 3 – 4 kg.
Drilling
techniques
• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard
tube, depth of diamond tails, face-sampling bit or other type, whether core is
oriented and if so, by what method, etc).
• The drilling was completed using diamond core rigs with PQ used from surface
to sample through to fresh-rock and HQ sized drill rods used after the top-of-
fresh-rock had been intersected. Most holes are angled between 50° and 75°
and collared from surface into weathered bedrock. All collars were surveyed
after completion. All holes were downhole surveyed using a digital multi-shot
camera at about 30 m intervals. Apart from drillholes MO17DD001,
MO17DD002, MO18DD001 and MO18DD008, all core was oriented.

Drill sample
recovery
• Method of recording and assessing core and chip sample recoveries and results
assessed.
• Measures taken to maximise sample recovery and ensure representative nature
of the samples.
• Whether a relationship exists between sample recovery and grade and whether
sample bias may have occurred due to preferential loss/gain of fine/coarse
material.
• Drill core recovery attained >97% in the pegmatite.
• Based upon the high recovery, AVZ did not have to implement additional
measures to improve sample recovery and the drill core is considered
representative and fit for sampling.
• For the vast majority of drilling completed, core recovery was near 100% and
there is no sample bias due to preferential loss or gain of fine or coarse
material.
Logging • Whether core and chip samples have been geologically and geotechnically
logged to a level of detail to support appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
• Whether logging is qualitative or quantitative in nature. Core (or costean,
channel, etc) photography.
• The total length and percentage of the relevant intersections logged.
• Drill core was logged by qualified geologists using a data-logger and the logs
were then uploaded into Geobank which is a part of the Micromine software
system. The core was logged for geology and geotechnical properties (RQD
& planar orientations). A complete copy of the data is held by an independent
consultant.
• All core was logged, and logging was by qualitative (lithology) and
quantitative (RQD and structural features) methods. All core was also
photographed both in dry and wet states, with the photographs stored in the
database.
• The entirety of all drillholes are logged for geological, mineralogical and
geotechnical data.

Sub-sampling
techniques and
sample
preparation
• If core, whether cut or sawn and whether quarter, half or all core taken.
• If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled
wet or dry.
• For all sample types, the nature, quality and appropriateness of the sample
preparation technique.
• Quality control procedures adopted for all sub-sampling stages to maximise
representivity of samples.
• Measures taken to ensure that the sampling is representative of the in situ
material collected, including for instance results for field duplicate/second-half
sampling.
• Whether sample sizes are appropriate to the grain size of the material being
sampled.
• Core is cut longitudinally, and half-core samples of a nominal 1 m length are
submitted for assay.
• The current programme is diamond core drilling.
• The sample preparation for drill core samples incorporates standard industry
practice. The half-core samples have been prepared at ALS Lubumbashi and
the ALS sample preparation facility on site at Manono, with holes from
MO18DD021 onwards being prepared at Manono.
• At AVZ’s onsite sample preparation facility the half-core samples of
approximately 4-5 kg are oven dried, crushed to -2 mm with a 500 g sub-
ample being split out. This 500 g sub-sample is then pulverised to produce a
pulp with 85% passing -75um size fraction. A 120 g subsample is then split
from this, the certified reference material, blanks and duplicates are inserted
at appropriate intervals and then the complete sample batch is couriered to
Australia for assay analysis.
• Standard sub-sampling procedures are utilised by ALS Lubumbashi and ALS
Manono at all stages of sample preparation such that each sub-sample split
is representative of the whole it was derived from.
• Duplicate sampling was undertaken for the drilling programme. After half-
core samples were crushed at the ALS Lubumbashi and ALS Manono
preparatory facility, an AVZ geologist took a split of the crushed sample which
is utilised as a field duplicate. The geologist placed the split into a pre-
numbered bag which was then inserted into the sample stream. It is then
processed further, along with all the other samples. The drilling produced PQ
and HQ drill core, providing a representative sample of the pegmatite which
is coarse-grained. Sampling was mostly at 1 m intervals, and the submitted
half-core samples typically had a mass of 3-4 kg.

Quality of assay
data and
laboratory tests
• The nature, quality and appropriateness of the assaying and laboratory
procedures used and whether the technique is considered partial or total.
• For geophysical tools, spectrometers, handheld XRF instruments, etc, the
parameters used in determining the analysis including instrument make and
model, reading times, calibrations factors applied and their derivation, etc.
• Nature of quality control procedures adopted (e.g. standards, blanks, duplicates,
external laboratory checks) and whether acceptable levels of accuracy (i.e. lack
of bias) and precision have been established.
• Diamond drillhole (core) samples were submitted to ALS Lubumbashi and ALS
Manono (DRC) where they were crushed and pulverised to produce pulps.
These pulps were couriered to Australia and analysed by ALS Laboratories in
Perth, Western Australia using a sodium peroxide fusion of a 5g charge
followed by digestion of the prill using dilute hydrochloric acid thence
determination by AES or MS, i.e. methods ME-ICP89 and ME-MS91. Samples
from the drilling completed in 2017 i.e. MO17DD001 and MO17DD002, were
assayed for a suite of 24 elements that included Li, Sn, Ta & Nb. Samples from
the drilling completed in 2018 were assayed for a suite of 12 elements; Li, Sn,
Ta, Nb, Al, Si, K, Fe, Mg, P, Th and U, with Li reported as Li2O, Al as Al2O3, Si as
SiO2, K as K2O, Mg as MgO, Fe as Fe2O3 and P as P2O5.
• Peroxide fusion results in the complete digestion of the sample into a molten
flux. As fusion digestions are more aggressive than acid digestion methods,
they are suitable for many refractory, difficult-to-dissolve minerals such as
chromite, ilmenite, spinel, cassiterite and minerals of the tantalum-tungsten
solid solution series. They also provide a more-complete digestion of some
silicate mineral species and are considered to provide the most reliable
determinations of lithium mineralisation.
• Sodium peroxide fusion is a total digest and considered the preferred method
of assaying pegmatite samples.
• Geophysical instruments were not used in assessing the mineralisation.
• For the drilling, AVZ incorporated standard QAQC procedures to monitor the
precision, accuracy and general reliability of all assay results from assays of
drilling samples. As part of AVZ’s sampling protocol, CRMs (standards), blanks
and duplicates were inserted into the sampling stream. In addition, the
laboratory (ALS Perth) incorporated its own internal QAQC procedures to
monitor its assay results prior to release of results to AVZ. The Competent
Person is satisfied that the results of the QAQC are acceptable and that the
assay data from ALS is suitable for Mineral Resource estimation.

Verification of
sampling and
assaying
• The verification of significant intersections by either independent or alternative
company personnel.
• The use of twinned holes.
• Documentation of primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols.
• Discuss any adjustment to assay data.
• MSA observed the mineralisation in the majority of cores on site, although no
check assaying was completed by MSA.
• MSA observed and photographed several collar positions in the field, along
with rigs that were drilling at the time of the site visit.
• Twinned holes for the verification of historical drilling, were not required. Short
vertical historical holes were drilled within the pit but are neither accessible
nor included within the database used to define the Mineral Resource.
• Drilling data is stored on site as both hard and soft copy. Drilling data is
validated onsite before being sent to data management consultants in Perth
where the data is further validated. When results are received, they are loaded
to the central database in Perth and shared with various stakeholders via the
cloud. QC results are reviewed by both independent consultants and AVZ
personnel at Manono. Hard copies of assay certificates are stored in AVZ’s
Perth offices.
• AVZ has not adjusted assay data.
Location of data
points
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole
surveys), trenches, mine workings and other locations used in Mineral Resource
estimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.
• The drillhole collars have been located by a registered surveyor using a Hi-
Target V30 Trimble differential GPS with an accuracy of +/- 0.02 m unless
otherwise noted.
• All holes were downhole surveyed using a digital multi-shot camera at
approximately 30 m intervals.
• For the purposes of geological modelling and estimation, the drillhole collars
were projected onto this topographic surface. In most cases adjustments were
within 1 m (in elevation).
• Coordinates are relative to WGS 84 UTM Zone 35M.
Data spacing
and distribution
• Data spacing for reporting of Exploration Results.
• Whether the data spacing and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral Resource and Ore
Reserve estimation procedure(s) and classifications applied.
• Whether sample compositing has been applied.
• Drillhole spacing was completed on sections 200 m apart, and collars were 50
to 100 m apart on section where possible.
Orientation of
data in relation
to geological
structure
• Whether the orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the deposit type.
• If the relationship between the drilling orientation and the orientation of key
mineralised structures is considered to have introduced a sampling bias, this
should be assessed and reported if material.
• The drillhole orientation is designed to intersect the Carrier de l’Este Pegmatite
at, or nearly at, 90° to the plane of the pegmatite.
• No material sampling bias exists due to drilling direction. For

Sample security • The measures taken to ensure sample security. • When utilizing ALS Lubumbashi, chain of custody is maintained by AVZ
personnel on-site to Lubumbashi. Samples are stored on-site until they are
delivered by AVZ personnel in sealed bags to the laboratory at ALS in
Lubumbashi. The ALS laboratory checked received samples against the sample
dispatch form and issues a reconciliation report.
• At Lubumbashi, the prepared samples (pulps) are sealed in a box and
delivered by DHL to ALS Perth.
• ALS issue a reconciliation of each sample batch, actual received vs
documented dispatch.
• The ALS Manono site preparation facility is managed independently by ALS
who supervise the sample preparation. Prepared samples are sealed in boxes
and transported by air to ALS Lubumbashi and are accompanied by an AVZ
employee, where export documentation and formalities are concluded. DHL
couriers the samples to ALS in Perth.
Audits or
reviews
• The results of any audits or reviews of sampling techniques and data. • The sampling techniques were reviewed by the Competent Person during the
site visit.
• The Competent Person considers that the exploration work conducted by AVZ
was carried out using appropriate techniques for the style of mineralisation at
Carriere de l’Este, and that the resulting database is suitable for Mineral
Resource estimation.

Mineral
tenement and
land tenure
status
• Type, reference name/number, location and ownership including agreements or
material issues with third parties such as joint ventures, partnerships, overriding
royalties, native title interests, historical sites, wilderness or national park and
environmental settings.
• The security of the tenure held at the time of reporting along with any known
impediments to obtaining a licence to operate in the area.
• The Manono licence was awarded as Research Permit PR13359, issued on the
28th December 2016 to o La Congolaise d’Exploitation Miniere SA (Cominiere).
It is valid for 5 years. On the 2nd February 2017, AVZ formed a joint-venture
(JV) with Cominiere and Dathomir Mining Resources SARL (Dathomir) to
become the majority partner in a JV aiming to explore and develop the
pegmatites contained within PR 13359. Ownership of the Manono Lithium
Project is AVZ 60%, Cominiere 30% and Dathomir 10%.
• AVZ manages the project and meets all funding requirements.
• All indigenous title is cleared and there are no other known historical or
environmentally sensitive areas.
Exploration
done by other
parties
• Acknowledgment and appraisal of exploration by other parties. • Within PR13359 exploration of relevance was undertaken by Geomines whom
completed a programme of drilling between 1949 and 1951. The drilling
consisted of 42 vertical holes drilled to a general depth of around 50 - 60 m.
Drilling was carried out on 12 sections at irregular intervals ranging from 50 -
300 m, and over a strike length of some 1,100 m. Drill spacing on the sections
varied from 50 - 100 m. The drilling occurred in the Roche Dure Pit only,
targeting the fresh pegmatite in the Kitotolo sector of the project area.
• The licence area has been previously mined for tin and tantalum through a
series of open pits over a total length of approximately 10 km excavated by
Zairetain SPRL. More than 60 Mt of material was mined from three major pits
and several subsidiary pits focused on the weathered upper portions of the
pegmatites. Ore was crushed and then upgraded through gravity separation
to produce a concentrate of a reported 72% Sn. There are no reliable records
available of tantalum or lithium recovery as tin was the primary mineral being
recovered.
• Apart from the mining excavations and the drilling programme, there has
been very limited exploration work within the Manono region.

Geology • Deposit type, geological setting and style of mineralisation. • The Project lies within the mid-Proterozoic Kibaran Belt - an intracratonic
domain, stretching for over 1,000 km through Katanga and into southwest
Uganda. The belt strikes predominantly SW-NE and is truncated by the N-S to
NNW-SSE trending Western Rift system. The Kibaran Belt is comprised of a
sedimentary and volcanic sequence that has been folded, metamorphosed
and intruded by at least three separate phases of granite. The latest granite
phase (900 to 950 million years ago) is assigned to the Katangan cycle and is
associated with widespread vein and pegmatite mineralisation containing tin,
tungsten, tantalum, niobium, lithium and beryllium. Deposits of this type occur
as clusters and are widespread throughout the Kibaran terrain. In the DRC, the
Katanga Tin Belt stretches over 500 km from near Kolwezi in the southwest to
Kalemie in the northeast comprising numerous occurrences and deposits of
which the Manono deposit is the largest. The geology of the Manono area is
poorly documented and no reliable maps of local geology were observed.
Recent mapping by AVZ has augmented the overview provided by Bassot and
Morio (1989) and has led to the following description. The Manono Project
pegmatites are hosted by a series of mica schists and by amphibolite in some
locations. These host rocks have a steeply dipping penetrative foliation that
appears to be parallel to bedding. There are numerous bodies of pegmatite,
the largest of which have sub-horizontal to moderate dips, with dip direction
being towards the southeast. The pegmatites post-date metamorphism, with
all primary igneous textures intact. They cross-cut the host rocks but despite
their large size, the contact deformation and metasomatism of the host rocks
by the intrusion of the pegmatites seems minor. The absence of significant
deformation of the schistosity of the host rocks implies that the pegmatites
intruded brittle rocks. The pegmatites constitute a pegmatite swarm in which
the largest pegmatites have an apparent en-echelon arrangement in a linear
zone more than 12 km long. The pegmatites are exposed in two areas;
Manono in the northeast, and Kitotolo in the southwest. These areas are
separated by a 2.5 km section of alluvium-filled floodplain which contains Lake
Lukushi. At least one large pegmatite extends beneath the floodplain. The
pegmatites are members of the LCT-Rare Element group of pegmatites and
within the pegmatite swarm there are LCT albite-spodumene pegmatites and
LCT Complex (spodumene sub-type) pegmatites.

Drill hole
Information
• A summary of all information material to the understanding of the exploration
results including a tabulation of the following information for all Material drill
holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level – elevation above sea level in metres) of the
drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
• If the exclusion of this information is justified on the basis that the information
is not Material and this exclusion does not detract from the understanding of
the report, the Competent Person should clearly explain why this is the case.
• See table for collar, survey and assay data.
Data
aggregation
methods
• In reporting Exploration Results, weighting averaging techniques, maximum
and/or minimum grade truncations (e.g. cutting of high grades) and cut-off
grades are usually Material and should be stated.
• Where aggregate intercepts incorporate short lengths of high grade results and
longer lengths of low grade results, the procedure used for such aggregation
should be stated and some typical examples of such aggregations should be
shown in detail.
• The assumptions used for any reporting of metal equivalent values should be
clearly stated.
• Intersections are reported as length-weighted grades within the logged
pegmatite.
• No grade truncations were applied.
• The majority of samples were taken at 1 m lengths.
• No equivalent values are used or reported.
Relationship
between
mineralisation
widths and
intercept
lengths
• These relationships are particularly important in the reporting of Exploration
Results.
• 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 (e.g. ‘down hole length, true width not known’).
• The majority of samples were taken at 1 m lengths.
• There is no relationship between mineralisation width and grade.
• The geometry of the mineralisation is reasonably well understood however
the pegmatite is not of uniform thickness nor orientation. Consequently, most
drilling intersections do not represent the exact true thickness of the
intersected pegmatite, although intersections are reasonably close to true
thickness in most cases.
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.
• The relevant plans and sections are included in this document.
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 pegmatite intersections for holes CD18DD005 and CD18DD006 are
reported.
