magnetite layer within the proposed open pit at Gabanintha. (See ASX Announcement dated 19 December 2018 ‘ Gabanintha Pre-Feasibility Study and Maiden Ore Reserve ’)

Detailed pilot scale test work will allow the planned processing flow diagram (PFD), to be tested on representative volumes of ore to ensure that the process is scaled up correctly for actual mine production. Full scale pilot studies are typical and best practice for projects of the size of AVL’s Gabanintha.

2019 Pilot Plant Drill Campaign

Collection of large diameter diamond core (PQ size) as test material for pilot scale studies is rapidly progressing. Diamond core of all material types in the high-grade massive magnetite layer is currently being drilled using downdip and vertical diamond drill holes. The drilling is being undertaken within AVL’s proposed open pit at Gabanintha.

Managing Director Vincent Algar comments, “The substantial thickness of the deposit has allowed the company to advance collection of material for the Pilot Study by carefully planned and executed downdip drilling (See Figure 2). The time and cost savings gained by using this method match our accelerated time line to 2021 production. Drilling is progressing exceptionally well, recovering high quality magnetite and proceeding ahead of schedule.”

Nine tonnes of drill core have already been delivered to an experienced laboratory in Perth, with the remainder to be delivered in regular intervals through February and March.

On completion, the drill program will provide AVL with:

  • Approximately 30 tonnes of oxide, transitional and fresh core samples required to run a robust pilot plant testwork program for the Crushing, Milling and Beneficiation (CMB) circuit;

  • Concentrate products from the CMB pilot plant testwork program for use in salt-roast leach and hydrometallurgical tests that will produce samples of refined vanadium pentoxide (V2O5); and

  • Information from these tests to be used to further refine the results of the Pre-Feasibility Study (PFS) released in December 2018.

Focused campaign

The current drilling campaign is focused on the northern 2km of AVL’s 11.5km deposit strike length and the collected tonnage is spread along the length of the pit defined by the PFS. The robust analysis of large volumes of typical material from within the Ore Reserve aims to distinguish AVL from its peers as the leading vanadium project of choice globally.

8 holes have been completed for 1,227m in the program to date. Table 1 shows the drill collars and orientations of the completed drillholes. Samples have not yet been sent for assay analysis, but detailed calibrated handheld XRF measurements and portable MagSus (Magnetic Susceptibility) measurements have been collected every 50cm along the core for detailed interpretation (see Plate 2). Hole 19MTDH006 drilled down dip of the massive magnetite horizon extended to 230m within the magnetite horizon (see Figure 2). This hole confirms the highly consistent nature of the Gabanintha mineralised zones as well as confirming the accuracy of the current resource model.

The drill program is due for completion in late March 2019 and is currently running ahead of schedule.

Gabanintha Project Path forward

Upon successful collection of the core for the Pilot Study, AVL’s Gabanintha project is on schedule for completion of the Pilot Study and DFS in 2019. The Company will then proceed into Front End Engineering Design (FEED) and construction in 2020 followed by start-up in 2021. Submission of a detailed environmental assessment for the project will occur upon completion of all required study work, to allow full assessment by the regulators.

The Company is active in the vanadium and financial markets, presenting the technical merits of the project to prospective partners and investors. The project is being very well received and the company is confident that a prospective investment partner will be found to join with AVL in the development of its Gabanintha Vanadium Project.

2019 Drilling Progress Update with latest Mineral Resource Estimate dated November 2018 (2012 JORC Code – Table 1)

Section 1: Sampling Techniques and Data

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.
The Gabanintha deposit was sampled using diamond core and reverse circulation (RC) percussion drilling from
surface.
During 2019 a further 8 PQ diamond drill holes have been completed, drilling down-dip of the high grade zone, to
collect metallurgy sample for a plant pilot study. These holes are being measured by hand-held XRF at 50 cm
intervals and will not form part of any resource estimation update unless certified laboratory analysis is completed on
a cut portion of the drill core.
At the time of the latest Mineral Resource estimation (November 2018), a total of 250 RC holes and 20 diamond
holes (6 of which are diamond tails) were drilled into the deposit. 59 of the 251 holes were either too far north or
east of the main mineralisation trend, or excised due to being on another tenancy. One section in the southern part
of the deposit (holes GRC0156, GRC0074, GRC0037 and GRC0038) was blocked out and excluded from the
resource due to what appeared to be an intrusion which affected the mineralised zones in this area. Of the
remaining 191 drillholes, one had geological logging but no assays and one was excluded due to poor sample
return causing poor representation of the mineralised zones. Two diamond holes drilled during 2018 were not part
of the resource estimate, as they were drilled into the western wall for geotechnical purposes. The total metres of
drilling available for use in the interpretation and grade estimation was 17,530m at the date of the most recent
resource estimate.
The initial 17 RC drillholes were drilled by Intermin Resources NL (IRC) in 1998. These holes were not used in the
2015 and 2017 estimates due to very long unequal sample lengths and a different grade profile from subsequent
drilling. 31 RC drillholes were drilled by Greater Pacific NL in 2000 and the remaining holes for the project were
drilled by Australian Vanadium Ltd (Previously Yellow Rock Resources Ltd) between 2007 and 2018. This drilling
includes 20 diamond holes (6 of which are diamond tails) and 76 RC holes, for a total of 20,974m drilled.
All of the drilling sampled both high and low-grade material and were sampled for assaying of a typical iron ore suite,
including vanadium and titanium plus base metals and sulphur.
Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
2019 PQ core has not been sampled. Handheld XRF machines being used to take ½ metre measurements on the
core have been calibrated using pulps from previous drilling by the Company, for which there are known head
assays. 2018 HQ diamond core was half-core sampled at regular intervals (usually one metre) with smaller sample
intervals at geological boundaries. 2015 diamond core was quarter-core sampled at regular intervals (usually one
metre) and constrained to geological boundaries where appropriate. 2009 HQ diamond core was half-core sampled
at regular intervals (one metre) or to geological boundaries. Most of the RC drilling was sampled at one metre
intervals, apart from the very earliest programme in 1998. RC samples have been split from the rig for all programs
with a cone splitter to obtain 2.5 – 3.5 kg of sample from each metre. Field duplicates were collected for every 40th
drill metre to check sample representativity from the drill rig splitter.

Criteria JORC Code Explanation Commentary
Aspects of the determination of
mineralisation that are Material to the Public
Report.
RC drilling samples were collected at one metre intervals and passed through a cone splitter to obtain a nominal 2-
5kg sample at an approximate 10% split ratio. These split samples were collected in pre-numbered calico sample
bags. The sample was dried, crushed and pulverised to produce a sub sample (~200g) for laboratory analysis using
XRF and total LOI by thermo-gravimetric analysis.
Diamond core was drilled predominantly at HQ size for the earlier drilling (2009) and entirely HQ for the 2018
program, with the 2015 and 2019 drilling at PQ3 size.
Field duplicates, standards and blanks have been inserted into the sampling stream at a rate of nominally 1:20 for
blanks, 1:20 for standards (including internal laboratory), 1:40 for field duplicates, 1:20 for laboratory checks and
1:74 for umpire assays.
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.).
Diamond drillholes account for 14% of the drill metres and comprises HQ and PQ3 sized core. RC drilling (generally
135 mm to 140 mm face-sampling hammer) accounts for the remaining 86% of the drilled metres. Six of the
diamond holes have RC pre-collars (GDH911, GDH913 & GDH916, 18GEDH001, 002 and 003), otherwise all holes
are drilled from surface.
No core orientation data has been recorded in the database.
17 RC holes were drilled during the 2018 program and three HQ diamond tails were drilled on RC pre-collars for
resource and geotechnical purposes. The core was not orientated but all diamond holes were logged by OTV and
ATV televiewer. Six RC holes from the 2018 campaign are not used in the resource estimate due to results pending
at the time of the latest update, and two diamond holes drilled during 2018 were not used as they are for
geotechnical purposes and do not intersect the mineralised zones.
During 2019 a further 8 PQ diamond holes have been drilled down-dip on the high-grade zone for metallurgical
sample, but have not been sampled for assay analysis, and do not form part of any resource estimation.
Drill sample
recovery
Method of recording and assessing core and
chip sample recoveries and results
assessed.
Diamond core recovery is measured when the core is recovered from the drill string. The length of core in the tray is
compared with the expected drilled length and is recorded in the database.
For the 2018 and 2015 drilling, RC chip sample recovery was gauged by how much of the sample was returned from
the cone splitter. This was recorded as good, fair, poor or no sample. The older drilling programmes used a different
splitter, but still compared and recorded how much sample was returned for the drilled intervals. All of the RC
sample bags (non-split portion) from the 2018 programme were weighed as an additional check on recovery.
An experienced AVL geologist was present during drilling and any issues noticed were immediately rectified.
No significant sample recovery issues were encountered in the RC drilling.
Measures taken to maximize sample
recovery and ensure representative nature
of the samples.
Core depths are checked against the depth given on the core blocks and rod counts are routinely carried out by the
drillers. Recovered core was measured and compared against driller’s blocks.
RC chip samples were actively monitored by the geologist whilst drilling.
All drillholes are collared with PVC pipe for the first metre or two, to ensure the hole stays open and clean from
debris.

Criteria JORC Code Explanation Commentary
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.
No relationship between sample recovery and grade has been demonstrated.
Two shallow diamond drillholes drilled to twin RC have been completed to assess sample bias due to preferential
loss/gain of fine/coarse material.
Geologica Pty Ltd is satisfied that the RC holes have taken a sufficiently representative sample of the mineralisation
and minimal loss of fines has occurred in the RC drilling resulting in minimal sample bias.
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.
All diamond core and RC chips from holes included in the latest resource estimate were geologically logged.
Diamond core was geologically logged using predefined lithological, mineralogical and physical characteristics (such
as colour, weathering, fabric, texture) logging codes and the logged intervals were based on lithological intervals.
RQD and recoveries were also recorded. Minimal structural measurements were recorded (bedding to core angle
measurements) but have not yet been saved to the database.
The logging was completed on site by the responsible geologist.
All of the drilling was logged onto paper and was transferred to a SQL Server drillhole database using DataShedTM
database management software. The database is managed by Mitchell River Group (MRG). The data was checked
for accuracy when transferred to ensure that correct information was recorded. Any discrepancies were referred
back to field personnel for checking and editing.
All core trays were photographed wet and dry.
RC chips were logged generally on metre intervals, with the abundance/proportions of specific minerals, material
types, lithologies, weathering and colour recorded.
Physical hardness for RC holes is estimated by chip recovery and properties (friability, angularity) and in diamond
holes by scratch testing.
From 2015, drilling also had magnetic susceptibility recorded, with the first nine diamond holes (GDH901-GDH909)
having readings taken on the core every 30 cm or so downhole. Holes GDH910 to GDH917 had readings every 50
cm and RC holes GRC0159 to GRC0221 had readings for every one metre green sample bag. 2018 RC drill holes
also have magnetic susceptibility data for each one metre of drilling.
All resource (vs geotechnical) diamond core and RC samples have been logged to a level of detail to support
Mineral Resource estimation to and classification to Measured Mineral Resource at best.
Geotechnical logging and OTV/ATV data was collected on three diamond drillholes from the 2018 campaign, by
consultant company Dempers and Seymour, adding to an existing dataset of geotechnical logging on 8 of the 2015
diamond drillholes and televiewer data for four of the same drillholes. In addition, during 2018 televiewer data was
collected on a further 15 RC drillholes from various drill campaigns at the project.
PQ diamond drill holes completed during 2019 have handheld XRF readings per half metre, in addition to KT-10
magnetic susceptibility readings at the same core locations. They are being geologically logged in detail by the site
geologists, and geotechnical logging is being completed, also at site.
Whether logging is qualitative or quantitative
in nature. Core (or costean, channel, etc.)
photography.
Logging was both qualitative and quantitative in nature, with general lithology information recorded as qualitative
and most mineralisation records and geotechnical records being quantitative. Core photos were collected for all
diamond drilling.
The total length and percentage of the
relevant intersections logged.
All recovered intervals were geologically logged.

and sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
The 2018 and 2009 HQ diamond core was cut in half and the half core samples were sent to the laboratories for
assaying. Sample intervals were marked on the core by the responsible geologist considering lithological and
structural features.
No core was selected for duplicate analysis.
The 2015 PQ diamond core was cut in half and then the right hand side of the core (facing downhole) was halved
again using a powered core saw. Quarter core samples were sent to the laboratories for assaying. Sample intervals
were marked on the core by the responsible geologist considering lithological and structural features.
No core was selected for duplicate analysis.
60% of the total PQ diamond drill holes from 2019 will be sampled, through cutting a wedge from the core. This
sample will be available for assay analysis. The portions of core to be sampled are still to be selected.
If non-core, whether riffled, tube sampled,
rotary split, etc. and whether sampled wet or
dry.
RC drilling was sampled by use of an automatic cone splitter for the 2018 and 2015 drilling programmes; drilling was
generally dry with a few damp samples. Older drilling programmes employed riffle splitters to produce the required
sample splits for assaying. One in 40 to 50 RC samples was resampled as field duplicates for QAQC assaying.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
The sample preparation techniques employed for the diamond core samples follow standard industry best practice.
All samples were crushed by jaw and Boyd crushers and split if required to produce a standardised ~3kg sample for
pulverising. The 2015 programme RC chips were split to produce the same sized sample.
All samples were pulverised to a nominal 90% passing 75 micron sizing and sub sampled for assaying and LOI
determination tests. The remaining pulps are stored at an AVL facility.
The sample preparation techniques are of industry standard and are appropriate for the sample types and proposed
assaying methods.
Quality control procedures adopted for all
sub-sampling stages to maximize
representivity of samples.
Field duplicates, standards and blanks have been inserted into the sampling stream at a rate of nominally 1:20 for
blanks, 1:20 for standards (including internal laboratory), 1:40 for field duplicates, 1:20 for laboratory checks and
1:74 for umpire assays. Also for the recent sampling at BV, 1 in 20 samples were tested to check for pulp grind size.
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.
To ensure the samples collected are representative of the in-situ material, a 140mm diameter RC hammer was used
to collect one metre samples and either HQ or PQ3 sized core was taken from the diamond holes. Given that the
mineralisation at Gabanintha is either massive or disseminated magnetite/martite hosted vanadium, which shows
good consistency in interpretation between sections and occurs as percentage values in the samples, Geologica Pty
Ltd considers the sample sizes to be representative.
Core is not split for duplicates, but RC samples are split at the collection stage to get representative (2-3kg)
duplicate samples.
The entire core sample and all the RC chips are crushed and /or mixed before splitting to smaller sub-samples for
assaying.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
As all of the variables being tested occur as moderate to high percentage values and generally have very low
variances (apart from Cr2O3), the chosen sample sizes are deemed appropriate.

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.
All samples for Gabanintha were assayed for the full iron ore suite by XRF (24 elements) and for total LOI by
thermo-gravimetric technique. The method used is designed to measure the total amount of each element in the
sample. Some 2015 RC samples in the oxide profile were also selected for SATMAGAN analysis that is a measure
of the amount of total iron that is present as magnetite (or other magnetic iron spinel phases, such as maghemite or
kenomagnetite). SATMAGAN analysis was conducted at Bureau Veritas (BV) Laboratory in early 2018. Analysis
results of the relevant portions of the RC holes by Satmagan are pending, but underway.
Although the laboratories changed over time for different drilling programmes, the laboratory procedures all appear
to be in line with industry standards and appropriate for iron ore deposits, and the commercial laboratories have
been industry recognized and certified
Samples are dried at 105oC in gas fired ovens for 18-24 hours before RC samples being split 50:50. One portion is
retained for future testing, while the other is then crushed and pulverised. Sub-samples are collected to produce a
66g sample that is used to produce a fused bead for XRF based analysing and reporting.
Certified and non-certified Reference Material standards, field duplicates and umpire laboratory analysis are used
for quality control. The standards inserted by AVL during the 2015 drill campaign were designed to test the V2O5
grades around 1.94%, 0.95% and 0.47%. The internal laboratory standards used have varied grade ranges but do
cover these three grades as well. During 2018, three Certified Reference Materials (CRMs) were used by AVL as
field standards. These covered the V2O5grade ranges around 0.327%, 0.790% and 1.233%. These CRMs are also
certified for other relevant major element and oxide values, including Fe, TiO2, Al2O3, SiO2, Co, Ni and Cu (amongst
others).
Most of the laboratory standards used show an apparent underestimation of V2O5, with the results plotting below the
expected value lines, however the results generally fall within ± 5-10% ranges of the expected values. The other
elements show no obvious material bias.
Standards used by AVL generally showed good precision, falling within 3-5% of the mean value in any batch. The
standards were not certified but compared with the internal laboratory standards (certified) they appear to show
good accuracy as well.
Field duplicate results from the 2015 drilling all fall within 10% of their original values.
The BV laboratory XRF machine calibrations are checked once per shift using calibration beads made using exact
weights and they performed repeat analyses of sample pulps at a rate of 1:20 (5% of all samples). The lab repeats
compare very closely with the original analysis for all elements.
2019 PQ diamond core is not yet sampled, but any core sampled will be subject to the same process outlined above
for previous drill campaigns.
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.
The only geophysical readings taken for the Gabanintha core and RC samples and recorded in the database were
magnetic susceptibility. For the 2009 diamond and 2015 RC and diamond drill campaigns this was undertaken using
an RT1 hand magnetic susceptibility meter (CorMaGeo/Fugro) with a sensitivity of 1 x 10–5(dimensionless units).
The first nine diamond holes (GDH901 – GDH909) were sampled at approximately 0.3m intervals, the last eight
(GDH910 – GDH917) at 0.5m intervals and the RC chip bags for every green bagged sample (one metre). During
2018 and 2019 RC and diamond core has been measured using a KT-10 magnetic susceptibility metre, at 1 x 10-3
ssi unit.
2019 diamond core is being analysed using an Olympus Vanta pXRF with a 20 second read time. The unit has been
calibrated using pulp samples with known head assays from previous drill campaigns by the Company. Standard
deviations for each element analysed is being recorded and retained. Elements being analysed are: Mg, Al, Si, P, S,
K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Ag, Cd, Sn, Sb, W, Hg, Pb, Bi, Th, and U.

Criteria JORC Code Explanation Commentary
Four completed diamond drillholes were down hole surveyed by acoustic televiewer (GDH911, 912, 914 and 915)
as a prequel to geotechnical logging during the 2015 drill campaign. A further six holes from the 2018 campaign
have been down hole surveyed using acoustic televiewer and optical televiewer (18GEDH001, 002 and 003 and
partial surveys of 18GERC005, 008 and 011) for 627 metres of data.
Televiewer data was also collected during 2018 on some of the holes drilled in 2015 and prior. The holes surveyed
were GRC0019, 0024, 0168, 0169, 0173, 0178, 0180, 0183, 0200 and Na253, Na258 and Na376 for a further
286.75 m of data.
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.
QAQC results from both the primary and secondary assay laboratories show no material issues with the main
variables of interest for the recent assaying programmes.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Diamond drill core photographs have been reviewed for the recorded sample intervals. Geologica Pty Ltd
Consultant, Brian Davis, visited the Gabanintha project site and the BV core shed and assay laboratories in
September 2015 and on multiple occasions over a 10 year period. Whilst on site, the drillhole collars and remaining
RC chip samples were inspected. All of the core was inspected in the BV facilities in Perth and selected sections of
drillholes were examined in detail in conjunction with the geological logging and assaying.
Resource consultants from Trepainier have visited the company core storage facility in Bayswater and reviewed the
core trays for select diamond holes.
The use of twinned holes. Two diamond drillholes (GDH915 and GDH917) were drilled to twin the RC drillholes GRC0105 and GRC0162
respectively. The results show excellent reproducibility in both geology and assayed grade for each pair.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
All primary geological data has been collected using paper logs and transferred into Excel spreadsheets and
ultimately a SQL Server Database. The data were checked on import. Assay results were returned from the
laboratories as electronic data which were imported directly into the SQL Server database. Survey and collar
location data were received as electronic data and imported directly to the SQL database.
All of the primary data have been collated and imported into a Microsoft SQL Server relational database, keyed on
borehole identifiers and assay sample numbers. The database is managed using DataShed™ database
management software. The data was verified as it was entered and checked by the database administrator (MRG)
and AVLpersonnel
Discuss any adjustment to assay data. No adjustments or calibrations were made to any assay data, apart from resetting below detection limit values to
half positive detection values.

Location of
data points
Accuracy and quality of surveys used to
locate drillholes (collar and down-hole
surveys), trenches, mine workings and other
locations used in Mineral Resource
estimation.
The 2019 drill holes have been set out using a real-time Kinematic (RTK) GPS system. Following completion of
drilling they are being picked up with a DGPS system (accuracy of about 20 cm resolution on the horizontal), prior to
getting a professional surveyor with an RTK system back to site for the final pick-up.
For the 2018 drilling, all collars were set out using a handheld GPS. After drilling they were surveyed using a
Trimble RTK GPS system. The base station accuracy on site was improved during the 2015 survey campaign and a
global accuracy improvement was applied to all drillholes in the Company database.
For the 2015 drilling, all of the collars were set out using a Trimble RTK GPS system. After completion of drilling all
new collars were re- surveyed using the same tool.
Historical drill holes were surveyed with RTK GPS and DGPS from 2008 to 2015, using the remaining visible collar
location positions where necessary. Only five of the early drillholes, drilled prior to 2000 by Intermin, had no obvious
collar position when surveyed and a best estimate of their position was used based on planned position data.
Downhole surveys were completed for all diamond holes, using gyro surveying equipment, as well as the RC holes
drilled in 2015 (from GRC0159). Some RC drillholes from the 2018 campaign do not have gyro survey as the hole
closed before the survey could be done. These holes have single shot camera surveys, from which the dip readings
were used with an interpreted azimuth (nominal hole setup azimuth). The holes with interpreted azimuth are all less
than 120m depth. All other RC holes were given a nominal -60odip measurement. These older RC holes were
almost all 120m or less in depth.
Specification of the grid system used. The grid projection used for Gabanintha is MGA_GDA94, Zone 50. All reported coordinates are referenced to this
grid.
Quality and adequacy of topographic control. High resolution Digital Elevation Data was captured by Arvista for the Company in June 2018 over the MLA51/878
tenement area using fixed wing aircraft, with survey captured at 12 cm GSD using an UltraCam camera system
operated by Aerometrex. The data has been used to create a high-resolution Digital Elevation Model on a grid
spacing of 5m x 5m, which is within 20 cm of all surveyed drill collar heights, once the database collar positions
were corrected for the improved ground control survey, that was also used in this topography survey. The vertical
accuracy that could be achieved with the 12 cm GSD is +/- 0.10 m and the horizontal accuracy is +/- 0.24m. 0.5m
contour data has also been generated over the mining lease application. High quality orthophotography was also
acquired during the survey at 12cm per pixel for the full lease area, and visual examination of the imagery shows
excellent alignment with the drill collar positions. The November 2018 Mineral Resource used this surface for
topographic control within the Mining Lease Application area (MLA51/878).
For the entire 2017 and July 2018 Mineral Resource estimates, and the November 2018 Mineral Resource estimate
outside the MLA area, high resolution Digital Elevation Data was supplied by Landgate. The northern two thirds of
the elevation data is derived from ADS80 imagery flown September 2014. The data has a spacing of 5M and is the
most accurate available. The southern third is film camera derived 2005 10M grid, resampled to match it with the
2014 DEM. Filtering was applied and height changes are generally within 0.5M. Some height errors in the 2005 data
may be +/- 1.5M when measured against AHD but within the whole area of interest any relative errors will mostly be
no more than +/- 1M.
In 2015 a DGPS survey of hole collars and additional points was taken at conclusion of the drill program. Trepanier
compared the elevations the drillholes with the supplied DEM surface and found them to be within 1m accuracy.

Criteria JORC Code Explanation Commentary
An improved ground control point has been established at the Gabanintha project by professional surveyors. This
accurate ground control point was used during the acquisition of high quality elevation data. As such, a correction to
align previous surveys with the improved ground control was applied to all drill collars from pre-2018 in the
Company drill database. Collars that were picked up during 2018 were already calibrated against the new ground
control.
2019 drill collar locations have been verified with a DGPS in the field (accuracy about 20 cm on the horizontal) with
final RTK pick up pending at completion of the drill program.
Data spacing
and
distribution
Data spacing for reporting of Exploration
Results.
The 2018 RC drilling in Fault Block 17 has infilled areas of 260 m spaced drill lines to about 130m spaced drill lines,
with holes on 30 m centres on each line.
The closer spaced drilled areas of the deposit now have approximately 80m to 100m spacing by northing and 25m
to 30m spacing by easting. Occasionally these spacings are closer for some pairs of drillholes. Outside of the main
area of relatively close spaced drilling (approximately 7015400mN to 7016600mN), the drillhole spacing increases
to several hundred metres in the northing direction, but maintains roughly the same easting separation as the closer
spaced drilled area.
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.
The degree of geological and grade continuity demonstrated by the data density is sufficient to support the definition
of Mineral Resources and the associated classifications applied to the Mineral Resource estimate as defined under
the 2012 JORC Code. Variography studies have shown very little variance in the data for most of the estimated
variables and primary ranges in the order of several hundred metres.
Whether sample compositing has been
applied.
All assay results have been composited to one metre lengths before being used in the Mineral Resource estimate.
This was by far the most common sample interval for the diamond drillhole and RC drillhole data.
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.
The grid rotation is approximately 45oto 50omagnetic to the west, with the holes dipping approximately 60oto the
east. The drill fences are arranged along the average strike of the high grade mineralised horizon, which strikes
approximately 310oto 315omagnetic south of a line at 7015000mN and approximately 330omagnetic north of that
line. The mineralisation is interpreted to be moderate to steeply dipping, approximately tabular, with stratiform
bedding striking approximately north-south and dipping to the west. The drilling is exclusively conducted
perpendicular to the strike of the main mineralisation trend and dipping approximately 60oto the east, producing
approximate true thickness sample intervals through the mineralisation.

Criteria JORC Code Explanation Commentary
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 orientation of drilling with respect to mineralisation is not expected to introduce any sampling bias. Drillholes
intersect the mineralisation at an angle of approximately 90 degrees.
The 2019 PQ diamond holes are deliberately being drilled down dip to maximise the amount of metallurgy sample
collected for the pilot study. They are not intended to add material to the resource estimation, or to define geological
boundaries.
Sample security The measures taken to ensure sample
security.
Samples were collected onsite under supervision of a responsible geologist. The samples were then stored in lidded
core trays and closed with straps before being transported by road to the BV core shed in Perth (or other
laboratories for the historical data). RC chip samples were transported in bulk bags to the assay laboratory and the
remaining green bags are either still at site or stored in Perth.
RC and core samples were transported using only registered public transport companies. Sample dispatch sheets
were compared against received samples and any discrepancies reported and corrected.
Audits or
reviews
The results of any audits or reviews of
sampling techniques and data.
A review of the sampling techniques and data was completed by Mining Assets Pty Ltd (MASS) and Schwann
Consulting Pty Ltd (Schwann) in 2008 and by CSA in 2011. Neither found any material error. AMC also reviewed
the data in the course of preparing a Mineral Resource estimate in 2015. The database has been audited and rebuilt
by AVL and MRG in 2015. In 2017 geological data was revised after missing lithological data was sourced.
Geologica Pty Ltd concludes that the data integrity and consistency of the drillhole database shows sufficient quality
to support resource estimation.
