TONNAGE DOUBLES IN MINERAL RESOURCE UPDATE FOR BOONANARRING PROJECT

_________________

Image Resources NL (ASX: IMA) (“Image” or “the Company”) is pleased to announce a doubling of the total tonnes of mineral resources for its 100%-owned Boonanarring Minerals Sand Project located 120 km north of Perth in the North Perth Basin .

As part of the bankable feasibility study being conducted for the Company’s high-grade Boonanarring and Atlas mineral sand projects, Optiro Pty Ltd ( Optiro ) has completed an update of the Mineral Resource estimate for Boonanarring in accordance with the guidelines of the JORC Code (2012). When compared to the Mineral Resource estimate for Boonanarring prepared for Image for its 2013 feasibility study, the total tonnes of Mineral Resources have increased by 103% from 21.5 million to 43.7 million tonnes , albeit at lower HM grade and mineral assemblage as detailed below.

A summary of the Mineral Resource estimate by Optiro for the Boonanarring deposit as at January 2017, reported at a cut-off grade of 2.0% total heavy minerals (HM), is presented in Table 1. The Mineral Resource summary from 2013, reported at a cut-off grade of 2.5% HM is shown in Table 2.

The principal reasons for the substantial increase in Mineral Resource tonnes reported in 2017 are:

  • An expanded area of mineralisation as a result of drilling completed since 2013;

  • Delineation of a substantially contiguous layer of lower grade mineralisation overlying the high-grade mineralised strands (Overlying Mineralisation) , previously thought to be discontinuous and sub-economic; and

  • Application of a lower cut-off grade (2.0% HM versus 2.5% in 2013).

Drilling since 2013 on the southern end of the deposit has extended the strike-length of Boonanarring Strandline Mineralisation from 11.2 km to 13.2 km and added approximately 5 million tonnes of Mineral Resources. In general, this additional mineralisation is significantly lower HM grade (~3.5% HM) and lower in overall mineral assemblage value (~8.5% zircon) than the previously reported main strandline mineralisation. However, this mineralisation is somewhat shallower (lower strip ratio) and therefore carries lower mining costs.

Delineation of the Overlying Mineralisation has added approximately 10 million tonnes of Mineral Resources at a 2.0% HM cut-off. As shown in the Table 1, this mineralisation is significantly lower HM grade and lower overall mineral assemblage value. It is unclear what quantity, if any, of this material will translate to ore reserves. However, given its relatively shallower depth compared to the high-grade Strandline Mineralisation, mining costs for this material will be lower.

The Overlying Mineralisation layer is potentially positively significant to the overall economics of the project in that any ore mined and processed from this overlying layer serves to reduce the overall mining strip ratio. In addition, the availability of additional tonnes Minerals Resources from the Overlying Mineralisation, and from lowering the cut-off grade, can potentially allow the ore processing rate to be increased without the sacrifice of mine life. This could lead to improved project economics by operating at a higher economy-of-scale without additional capital cost, by simply utilising the available capacity of the recently acquired wet concentration plant and associated equipment.

It is important to note that while the expanded Mineral Resource estimate by Optiro is reported as substantially higher tonnes than the 2013 Mineral Resource estimate, it remains to be determined what quantity of these additional tonnes of mineralisation will translate to economic reserves. In addition, further economic modelling must be completed to determine if portions of the lower grade Overlying Mineralisation will be economic to process in the shorter term, given current lower mineral sand commodity prices, or whether this lower grade material will need to be stockpiled for later processing under higher commodity prices.

The 2017 Mineral Resource estimate will be incorporated in updated mine design, modelling and scheduling for use in economic modelling of the project as part of the bankable feasibility study currently scheduled to be completed by the end of March 2017. A full copy of the summary report of the Mineral Resource estimate by Optiro is attached.

Dear Sir,

BOONANARRING MINERAL RESOURCE ESTIMATE – JANUARY 2017

Optiro has prepared an updated Mineral Resource estimate for the Boonanarring deposit. The Boonanarring Heavy Minerals Sands deposit is located in the North Perth Basin, Western Australia, approximately 120 km north of Perth.

Mineral Resource Summary

Image Resources NL (Image) prepared a Feasibility Study to assess the viability of mining and processing mineral sands from its Boonanarring deposit using a Mineral Resource estimate prepared in 2013. Optiro’s updated Mineral Resource, for January 2017, incorporates results from an additional 211 drill holes (for a total 8,300 m) drilled by Image between 2014 and 2016 and an additional 48 composite samples that were analysed to determine the heavy mineral (HM) assemblage components. The 2017 Mineral Resource has been defined from drilling undertaken by Iluka (the previous owners of the project) from 1998 to 2007 and by Image from 2011 to 2016 and comprises data from 1,513 vertical, reverse circulation (aircore) drill holes for a total of 62,499.5 m. The drill hole spacing is generally 20 m to 40 m across strike on section lines spaced at 100 m or 200 m along strike. Some areas have been drilled at a wider spacing of up to 80 m by 400 m.

The Boonanarring mineralisation is hosted by the Pleistocene Yoganup Formation. The Yoganup Formation is a buried pro-graded shoreline deposit, with dunes, beach ridge and deltaic facies. This formation lies unconformably over the Lower Cretaceous Leederville Formation and is overlain by the Quaternary Bassendean Sand. The basement to the main standline mineralisation is identified by the increased slimes content of the Leederville Formation. Some lower grade mineralisation that overlies the standlines may have been concentrated in an aeolian setting.

The heavy minerals within the Yoganup Formation have been concentrated in two main strandlines that are continuous over a north-south strike length of 13.2 km and have a combined across strike width of up to 500 m. The main strandline mineralisation extends from 14 m to 58 m depth and the overlying mineralisation extends from surface to a depth of 39 m. Mineralisation has been identified in the Leederville Formation, below the main strandlines, that extends from a depth of 20 m to 61 m. An

==> picture [118 x 20] intentionally omitted <==

BOONANARRING MINERAL RESOURCE ESTIMATE – JANUARY 2017

==> picture [105 x 45] intentionally omitted <==

additional strandline, to the west of the main strandlines, is present in the southern part of the project area. This western strandline has been shown from drilling to extend for approximately 4 km north-south, has an across strike width of up to 200 m and extends from 11 m to 35 m depth. The main and western strandline mineralisation was interpreted using a nominal cut-off grade of 2% HM and the mineralisation overlying the strandlines was interpreted using a nominal cut-off grade of 1.8% HM.

The majority of samples (98%) are from intervals of 1 m and Image collected samples of ~1.25 kg for each 1 m down hole interval. Almost 43% of samples have been analysed for total HM, slimes and oversize. Samples were analysed for HM content by heavy media separation. Almost 50% of the assayed intervals have been analysed using a <53 µm grain size for slimes and a -2mm+53µm grain size for HM, and almost 50% of the data has been analysed using a <63 µm grain size for slimes and a -1mm+63um grain size for HM. Less than 2% of the HM data is from a grain size fraction of -1mm+53µm. Grain size analysis was used to generate adjustment factors that have been applied to convert the +53 µm HM data to +63 µm HM data and to convert the -53 µm slimes data to -63 µm slimes data. Grain size analysis indicates that the zircon and TiO2 minerals are all ≤850 µm.

The Mineral Resource includes the results of 292 composite samples (from 569 holes totalling 3,799 m) which were analysed to determine the HM assemblage. The mineral assemblage data includes data from Iluka (magnetic separation followed by density separation using solutions of 3.85 g/cm[3] and 4.05 g/cm[3] ); XRF data (after microscope examination to exclude non-representative samples e.g. laterite); and QEMSCAN data. The results from QEMSCAN analysis of 20 composite samples, originally analysed using XRF, were used to calibrate the results from XRF with the QEMSCAN results. The QEMSCAN rules for the titanium mineral determination are ilmenite: 50-70% TiO2; leucoxene: 70-95% TiO2; and rutile: >95% TiO2.

HM, slimes and oversize block grades were estimated using ordinary kriging techniques with top-cuts applied to the data. Block grades were estimated for the mineral assemblage components (ilmenite, rutile, leucoxene and zircon) using inversed distance (squared) techniques.

Bulk density was determined using a formula supplied by Image. The formula, which is based on heavy mineral and slimes percentage concentrations and includes assumptions about void space and mineral densities, was calibrated with 19 bulk density measurements from the 2016 geotechnical drilling program.

The estimate has been classified according to the guidelines of the JORC Code (2012) into Measured, Indicated and Inferred Mineral Resources taking into account data quality, data density, geological continuity, grade continuity and confidence in the estimation of heavy mineral content and mineral assemblage. Measured Resources are generally defined where drilling is at 20 m to 40 m on 100 m spaced section lines, Indicated Resources are generally defined where drilling is at 20 m to 40 m by 200 m, and Inferred Resources are defined where the drill spacing is up to 80 m by 400 m. The Mineral Resource estimate for the Boonanarring deposit has been reported in Table 1 at a 2.0% total heavy minerals cut-off grade. This cut-off grade was selected by Image based on technical and economic assessment carried out during Feasibility Studies. The Mineral Resource is reported by mineralisation type and for a range of total heavy minerals cut-off grades in Table 2.

BOONANARRING MINERAL RESOURCE ESTIMATE – JANUARY 2017

==> picture [105 x 45] intentionally omitted <==

Open pit mining methods will be used, similar to those commonly and currently in use in heavy mineral sand mining operations both in Australia and globally. Process test work has shown that the valuable heavy minerals (zircon, ilmenite, rutile and leucoxene) can be recovered using standard mineral sands processing techniques.

Environmental exclusion zones, within 50 m of the Bartlett’s Well and the Boonanarring Nature Reserves, have been defined and these areas are excluded from the reported Mineral Resource. Buffers around major roads and the Dampier to Bunbury pipeline were applied to remove these areas from the Mineral Resource.

JORC Code, 2012 Edition – Table 1

The table below summaries the assessment and reporting criteria used for the Boonanarring deposit Mineral Resource estimate and reflects the guidelines in Table 1 of The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2012).

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling. 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
PublicReport.

Sampling of the deposit has been by vertical reverse-
circulation air-core method (RCAC). This is a Mineral sands
industry-standard drilling technique.

Samples are from intervals of 0.5 m, 0.7 m, 1 m and 1.5 m and
2 m. The majority of samples (98%) are from intervals of 1 m.

11 vertical diamond core holes were drilled in 2016 to obtain
geotechnical and bulk density data.
Drilling
techniques

Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details
(eg 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).

All Image RCAC drill holes are drilled vertically using an NQ-
sized (76 mm diameter) drill bit.

All Iluka RCAC drill holes are vertical and were drilled using a
BQ-sized drill bit (60 mm diameter).

Water injection is used to convert the sample to a slurry so it
can be incrementally sampled by a rotary splitter.

20 vertical diamond core holes were drilled in 2016 using a PQ
sized drillbit (85mm) diameter).
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.

At the drill site, Image’s geologist estimates sample recovery
qualitatively (as good, moderate or poor) for each 1 m down
hole sampling interval. Specifically, the supervising geologist
visually estimates the volume recovered to sample and reject
bags based on prior experience as to what constitutes good
recovery.

Image has recorded that over 90% of the samples have good
recovery and that less than 5% have moderate recovery and
less than 5% have poor recovery.

Image also monitors recovery through the mass of the
laboratory sample, which is recorded prior to despatch and
again on delivery to the laboratory. The mass variation in the
laboratory samples can then be correlated back to the original
totalsample.
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.

Image’s supervising geologist logs the sample reject material
at the rig and pans a small sub-sample of the reject, to visually
estimate the proportions of sands, heavy mineral (HM) sands,
‘slimes’ (clays), and oversize (rock chips) in each sample, in a
semi-quantitative manner.

The geologist also logs colour, grainsize, an estimate of
induration (a hardness estimate) and sample ‘washability’
(ease of separation of slimes from sands by manual attrition).

To preclude data entry and transcription errors, the logging
data is captured into a digital data logger at the rig, which
contains pre-set logging codes.

No photographs of samples are taken.

The digital logs are downloaded daily and emailed toImage’s

head office for data security and compilation into the main
database server.

Samples visually estimated by the geologist to contain more
than 0.5% HM (by weight) are despatched for analysis along
with the 1 m intervals above and below the mineralised
interval.

The level and detail of logging is of sufficient quality to support
Mineral Resource estimates (MRE).

All (100%) of the drilling is logged.

Geotechnical holes have been logged and assessments as to
pit stability determined.
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.

The majority of the samples (98%) are from 1 m intervals and
almost 43% of samples were analysed for total HM, slimes
and oversize.

The sample from the internal RC rods is directed to a cyclone
and then through a ‘rotating-chute’ custom-built splitting
device. This device allows different fraction splits from the
cyclone sample stream to be directed to either 25 cm by 35
cm calico bags (as the laboratory despatch samples) or to
large plastic polyweave bags for the sample rejects. The
rotary splitter directs≈10 increments from the stream to the
laboratory despatch samples, for a specified sampling interval.

Sample tickets with the interval’s unique sample ID are placed
in each bag.

For resource definition drilling, two (replicate) 1/8 mass splits
(each≈1.25 kg) are collected from the rotary splitter into two
pre-numbered calico bags for each 1 m down hole interval. A
selection of the replicate samples are later collected and
analysed to quantify field sampling precision, or as samples
contributing to potential future metallurgical composites.

Iluka is understood to have used a similar procedure albeit no
records are available to support this assertion.

To monitor sample representation and sample number
correctness, Image weighs the laboratory despatch samples
prior to despatch. The laboratory then weighs the received
sample and reports the mass to Image. This identifies any
potential mix up of sample numbers and is also a proxy for
sample recovery.

Image considers the nature, quality and size of the sub
samples collected are consistent with best industry practices

Image and Iluka used industry standard approaches to
estimating the contents of HM, slimes and oversize involving
screening to remove oversize, washing slimes from samples
and then extracting the heavy minerals from the residual
sands using heavy media.

Image engaged four laboratories (Western Geolabs,
Diamantina Laboratory, Diamond Recovery Services
Laboratory and Robbins Metallurgical Laboratory).

Iluka used a few certified reference materials (CRMs) to
quantify the accuracy of the drilling with acceptable results.
Image inserted CRMs for drilling undertaken during 2014,
2015 and 2016.

Both Iluka and Image collected duplicate samples including

have been established.
the laboratory sub-sampling stage (post de-sliming) and
laboratory re-submission duplicates to the original or
alternative laboratories used by Iluka and/or Image.

Analysis of QAQC data for the drilling programs indicates that
it is of moderate to high quality and supports Mineral Resource
estimation.

Three sets of mineral assemblage data have been used to
estimate the ilmenite, leucoxene, rutile and zircon
concentrations within the HM:
− data from Iluka (magnetic separation followed by density
separation using solutions of 3.85 g/cm3and 4.05 g/cm3)
− XRF data (after microscope examination to exclude non-
representative samples e.g. laterite)
− QEMSCANdata.
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.

Image drilled a number of twin holes (within 10 m of Iluka
holes). The twin holes compare favourably for HM and slimes
grades. Oversize grades could not be compared as Image and
Iluka use different size thresholds for oversize.

Image collected primary data on hard copy logs and also used
a data logger. Data from laboratories was provided in digital
form and compiled in Microsoft Access databases and
spreadsheets.

Almost 50% of the assayed intervals have been analysed
using a <53 µm grain size for slimes and a -2mm+53µm grain
size for HM, and almost 50% of the data has been analysed
using a <63 µm grain size for slimes and a -1mm+63um grain
size for HM. Less than 2% of the HM data is from a grain size
fraction of -1mm+53µm Grain size analysis was used to
generate adjustment factors that have been applied to convert
the +53 µm HM data to +63 µm HM data and to convert the
-53 µm slimes data to -63 µm slimes data.

Grain size analysis indicates that the zircon and TiO2minerals
are all ≤850 µm.

Results from QEMSCAN analysis of 20 composite samples,
originally analysed using XRF, were used to calibrate the
resultsfrom XRF withthe QEMSCAN results.
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.

Drill hole collars at Boonanarring have been surveyed using
hand-held DGPS and RTK DGPS methods, with the latter
method deemed most accurate.

The collar coordinates and survey ground controls have been
tied to the Landgate GOLA database by a registered surveyor.

All collars for the Mineral Resource estimate have been
adjusted to a LiDAR topographic model described below.

Data for Boonanarring has been surveyed in MGA Zone 50
GDA94. The Mineral Resource has been estimated in a local
grid system based on a two-point transformation. This
transformation has been validated by Image’s survey
contractor.

The topographic model for Boonanarring is based on LiDAR
survey. A review of this survey by Image’s survey contractor
revealed that the survey had an incorrect vertical datum;
elevations are 0.3 m higher than measured at collars using
RTK DGPS. The corrected LiDAR surface was used to
constrain the Mineral Resource model.

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.

The drill hole spacing is generally 20 m to 40 m across strike
on section lines spaced at 100 m or 200 m along strike. Some
areas have been drilled at a wider spacing of up to 80 m by
400 m.

The drill database used in the resource estimate comprises
1,513 drill holes for a total 62,499.5 m drilled by Image and
Iluka between 1998 and 2016.

Samples for HM assemblage determination were composited
on intervals according to a combination of grade and geology
appropriate to reflect resource estimation domains. 292
composites from 569 holes totalling 3,799 m were used in the
Mineral Resource estimate.

The data spacing and distribution is sufficient to establish the
degree of geological and grade continuity appropriate for the
Mineral Resource estimation procedure and classification
applied.
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.

All drill holes are vertical and intersect sub-horizontal strata.
This is appropriate for the orientation of the mineralisation and
will not have introduced a bias.
Sample
security

The measures taken to ensure sample
security.

All samples are collected from site by Image’s staff as soon as
practicable once drilling is completed and then delivered to
Image’s locked storage sheds.

Image’s staff deliver samples to the laboratory and collect
heavy mineral floats from the laboratory, which are also stored
in Image’s locked storage.

Image considers there is negligible risk of deliberate or
accidental contamination of samples. Occasional sample mix-
ups are corrected using Images checking and quality control
procedures..
Audits or
reviews

The results of any audits or reviews of
sampling techniques and data.

The results and logging have been reviewed internally by
Image’s senior exploration personnel including checking of
masses despatched and delivered, checking of CRM results,
and verification logging of significant intercepts.

The database, sampling procedures and documentation were
reviewed by Harlequin Consulting Pty Ltd in 2015.

In April 2013, CSA Global audited Robbins Metallurgical
Laboratory and found the laboratory practices acceptable to
supportresultsfor Mineral Resource estimation

Acknowledgment and appraisal of
exploration by other parties.

The Boonanarring deposit was discovered by Iluka, who drilled
out the central area to a Measured Resource status. The work
is well documented in reports from Iluka, prior Mineral
Resource estimators McDonald Speijers (2005) and Widenbar
and Associates (2013), and Harlequin Consulting Pty Ltd
(2014and2015).
Geology
Deposit type, geological setting and
style of mineralisation.

Boonanarring is hosted in the Perth Basin, in the Pleistocene
Yoganup Formation on the eastern margin of the Swan
Coastal Plain.

The Yoganup Formation is a buried pro-graded shoreline
deposit, with dunes, beach ridge and deltaic facies. This
formation lies unconformably over the Lower Cretaceous
Leederville Formation and is overlain by the Quaternary
Bassendean Sand.

The Yoganup Formation consists of unconsolidated poorly
sorted sands and gravels, with local interstitial clay and heavy
minerals that occur sporadically along the Gingin Scarp, which
is interpreted to be an ancient shoreline that was stable during
a period of marine regression.

Boonanarring has three major strandlines of heavy minerals,
which are interpreted to have been deposited during the
Pleistocene in a notch in the local basement rock that may
represent an ancient sea cliff. Lower grade mineralisation is
present in the sands overlying the higher grade strandlines.

The basement to the standline mineralisation is identified by
the increased slimes content of the Leederville Formation.
Mineralisation withinthishashigh zirconconcentrations.

maximum and/or minimum grade
truncations (eg cutting of high grades)
and cut-off grades are usually Material

Where aggregate intercepts incorporate
short lengths of high grade results and

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

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.

The geometry of the Boonanarring mineralisation is effectively
horizontal and the vertical drill holes used to define the Mineral
Resource give the approximate true thicknesses of
mineralisation.

Section 3 Estimation and Reporting of Mineral Resources

Criteria JORC Code explanation Commentary
Database
integrity

Measures taken to ensure that data
has not been corrupted by, for
example, transcription or keying errors,
between its initial collection and its use
for Mineral Resource estimation
purposes.

Data validation procedures used.

The drill hole database is managed by CSA and has been
compiled from Image’s internal databases and from databases
provided by Iluka. Maintenance of the database includes
internal data validation protocols by CSA and Image.

Harlequin Consulting Pty Ltd completed a high level review of
the database in 2015 and found the method of construction of
the database and validation procedures are acceptable and
that the data is acceptable for Mineral Resource estimation.

For the Mineral Resource estimate the drill hole data was
extracted directly from the CSA drill hole database.

Data was further verified and validated by Optiro using mining
software (Datamine) validation protocols, and visually in plan
and section views.
Site visits
Comment on any site visits undertaken
by the Competent Person and the
outcome of those visits.

Mrs Christine Standing (CP for the Mineral Resource estimate)
visited the Boonanarring deposit during December 2016.

The sites of the geotechnical drill holes and exclusion zones
for reporting oftheMineral Resourceswereinspected.
Geological
interpretation

Confidence in (or conversely, the
uncertainty of) the geological
interpretation of the mineral deposit.

Nature of the data used and of any
assumptions made.

The effect, if any, of alternative
interpretations on Mineral Resource
estimation.

The use of geology in guiding and
controlling Mineral Resource
estimation.

The factors affecting continuity both of
grade and geology.

Two stratigraphic (Yoganup and Leederville Formations) units
within the deposit area were defined using a combination of
slimes and oversize data and drill hole lithological logs.

For the purposes of resource estimation, these units were
used in combination with grade criteria to define four
mineralised domains, as follows:
− main strandlines: within Yoganup Fm., grade criteria
>2% HM
− western strandline: within Yoganup Fm., grade criteria
>2% HM
− below main strandlines: within Leederville Fm., grade
criteria >2% HM
− mineralisation overlying the main strandlines, within
Yoganup Fm., grade criteria >1.8% HM.

There is good confidence in the geological interpretation of the
main strandlines. Confidence in the other three domains is
lower, asreflected by the classification.
Dimensions
The extent and variability of the
Mineral Resource expressed as length
(along strike or otherwise), plan width,
and depth below surface to the upper
and lower limits of the Mineral
Resource.

The main strandline mineralisation has been shown from
drilling to extend for approximately 13.2 km north/south and
have a combined across strike width of up to 500 m. The
strandline mineralisation extends from 14 m to 58 m depth.
The mineralisation below the main strandline extends from a
depth of 20 m to 61 m and the overlying, lower grade
mineralisationextendsfromsurface to a depthof39m.

The western strandline has been shown from drilling to extend
for approximately 4 km north/south and has an across strike
width of up to 200 m. The mineralisation extends from 11 m to

Estimation
and modelling
techniques

The nature and appropriateness of the
estimation technique(s) applied and
key assumptions, including treatment
of extreme grade values, domaining,
interpolation parameters and maximum
distance of extrapolation from data
points. If a computer assisted
estimation method was chosen include
a description of computer software and
parameters used.

The availability of check estimates,
previous estimates and/or mine
production records and whether the
Mineral Resource estimate takes
appropriate account of such data.

The assumptions made regarding
recovery of by-products.

Estimation of deleterious elements or
other non-grade variables of economic
significance (e.g. sulphur for acid mine
drainage characterisation).

In the case of block model
interpolation, the block size in relation
to the average sample spacing and the
search employed.

Any assumptions behind modelling of
selective mining units.

Any assumptions about correlation
between variables.

Description of how the geological
interpretation was used to control the
resource estimates.

Discussion of basis for using or not
using grade cutting or capping.

The process of validation, the checking
process used, the comparison of
model data to drill hole data, and use
of reconciliation data if available.

Datamine resource estimation software was used to create a
geological model and define the mineralisation envelopes. A
series of mineralised domains was used to constrain the
Mineral Resource estimate.

Wireframe interpretations of mineralisation were made by
Optiro based on geological logging and HM content, using
thresholds of ~1.8% HM to define the overlying mineralisation
and 2% HM to define the strandline mineralisation.

Optiro assessed the robustness of these domains by critically
examining the geological interpretation and by using a variety
of measures, including statistical and geostatistical analysis.
The domains are considered geologically robust in the context
of the resource classification applied to the estimate.

Drill hole sample data was flagged from the three dimensional
interpretation of the mineralised horizons.

Samples are from intervals of 0.5 m, 0.7 m, 1 m and1.5 m and
2 m. As the majority of samples (98%) are from intervals of
1 m the data was composited to 1 m downhole intervals for
resource estimation.

Extrapolation of up to 50 m along strike and approximately half
the drill spacing across strike was used for the interpretation.

HM, slimes and oversize quantities were estimated using
ordinary kriging (OK) into blocks of 10 mE by 50 mN by
1 mRL.

Zircon, leucoxene, rutile and ilmenite (VHM components)
percentages within the HM fraction were estimated using
inverse distance (ID) into the parent blocks.

Block dimensions were selected from kriging neighbourhood
analysis and reflect the variability of the deposit and the
model’s practicality for future mine planning. Sub-cells to a
minimum dimension of 2.5 mE by 12.5 mN by 0.5 mRL were
used to represent volume.

Drill holes are generally spaced at 20 m on-section on lines
that are 100 m and 200 m apart with areas drilled at a spacing
of up to 80 m by 400 m.

Data analysis and estimation was undertaken using Snowden
Supervisor and Datamine software.

All variables were estimated separately and independently.

Hard boundaries were applied to the estimation of HM, slimes
and oversize and the VHM components within the
mineralisation domains.

Grade capping was applied to HM%, slimes% and oversize%.
The top cut levels were determined using a combination of top
cut analysis tools, including grade histograms, log probability
plots and the coefficient of variation.

Variogram analysis was undertaken to determine the kriging
estimation parameters used for OK estimation of HM, slimes
and oversize and the search dimensions used for ID
estimation of the VHM components.

HM mineralisation continuity was interpreted from variogram
analyses tohave analong strikerange of 1,140mand an

across strike range of 40 m within the main strandlines. Within
the other mineralised domains along strike continuity has
ranges of 485 m to 600 m and across strike ranges of 50 m to
90 m.

The VHM continuity was interpreted from variogram analyses
to have an along strike range of 1,400 m and an across strike
range of 110 m within the main strandline. Ranges of 800 m
by 130 m were interpreted for the upper mineralisation and
ranges of 600 m by 75 m were interpreted for the
mineralisation below the main strandlines.

Kriging neighbourhood analysis was performed in order to
determine the block size, sample numbers and discretisation
levels.

Three estimation passes were used for HM; the first search
was based upon the variogram ranges; the second search
was the same as the initial search with reduced sample
numbers required for estimation and the third search was up
to four times the initial search for the main and western
standlines and upper mineralisation. For the mineralisation
below the main strandline the third search was up to 8 times
the initial search. The majority of blocks (93%) were estimated
in the first pass, 5% in the second pass and 2% in the third
pass.

The HM, slimes and oversize estimated block model grades
were visually validated against the input drill hole data and
comparisons were carried out against the declustered drill hole
data and by northing, easting and elevation slices.

The VHM estimated block model grades were visually
validated against the input drill hole data and comparisons
were carried out against the drill hole data and by northing and
easting slices.
Moisture
Whether the tonnages are estimated
on a dry basis or with natural moisture,
and the method of determination of the
moisture content.

Tonnages are estimated on a dry basis.
Cut-off
parameters

The basis of the adopted cut-off
grade(s) or quality parameters applied.

The Mineral Resource estimate for the Boonanarring deposit
has been reported at a 2.0% HM cut-off. This cut-off grade
was selected by Image based on technical and economic
assessment carried out during Feasibility Studies.
Mining factors
or
assumptions

Assumptions made regarding possible
mining methods, minimum mining
dimensions and internal (or, if
applicable, external) mining dilution. It
is always necessary as part of the
process of determining reasonable
prospects for eventual economic
extraction to consider potential mining
methods, but the assumptions made
regarding mining methods and
parameters when estimating Mineral
Resources may not always be
rigorous.

Open pit mining methods will be used, similar to those
commonly and currently in use in HM mining operations both
in Australia and globally.

Image has assumed mining by conventional truck and
shovels, with dozers used to improve vertical selectivity.

Metallurgical
factors or
assumptions

The basis for assumptions or
predictions regarding metallurgical
amenability. It is always necessary as
part of the process of determining
reasonable prospects for eventual
economic extraction to consider
potential metallurgical methods, but the
assumptions regarding metallurgical
treatment processes and parameters
made when reporting Mineral
Resources may not always be
rigorous.

Mineral assemblage data within the Mineral Resource
estimate has been sourced from three different assemblage
programs:
− data from Iluka (magnetic separation followed by
density separation using solutions of 3.85 g/cm3and
4.05 g/cm3)
− XRF data (after microscope examination to exclude
non-representative samples e.g. laterite)
− QEMSCAN data.

Results from QEMSCAN analysis of 20 composite samples,
originally analysed using XRF, were used to calibrate the
results from XRF with the QEMSCAN results.

The QEMSCAN rules for the titanium mineral determination
are as follows:
− Ilmenite: 50-70% TiO2
− Leucoxene: 70-95% TiO2
− Rutile: >95% TiO2

Process metallurgical studies of bulk samples from
Boonanarring were undertaken in 2013, 2015 and 2016 for the
purpose of developing a process flowsheet for the deposit.
The results from this work are sufficient for Image to expect
that the Boonanarring mineralisation will be amenable to
treatment with conventional mineral sands processing
techniques.

Image considers there are no metallurgical factors which are
likely to affect the assumption that the deposit has reasonable
prospectsforeventualeconomic extraction.
Environmental
factors or
assumptions

Assumptions made regarding possible
waste and process residue disposal
options. It is always necessary as part
of the process of determining
reasonable prospects for eventual
economic extraction to consider the
potential environmental impacts of the
mining and processing operation.

Environmental exclusion zones, within 50 m of the Bartlett’s
Well and Boonanarring Nature Reserves, have been defined
and these areas are excluded from the reported Mineral
Resource.
Bulk density
Whether assumed or determined. If
assumed, the basis for the
assumptions. If determined, the
method used, whether wet or dry, the
frequency of the measurements, the
nature, size and representativeness of
the samples.

The bulk density for bulk material must
have been measured by methods that
adequately account for void spaces
(vugs, porosity, etc), moisture and
differences between rock and
alteration zones within the deposit.

Discuss assumptions for bulk density
estimates used in the evaluation
process of the different materials.

19 bulk density measurements were made during the 2016
geotechnical drilling program.

Previous resource estimates (2013) used bulk density values
predicted from an industry-standard formula which accounts
for the HM and slimes content of heavy mineral sand deposits.

The formula was found to overstate the bulk density. The
formula was calibrated with the 2016 data for estimation of the
bulk density for the 2017 Mineral Resource estimate.

Classification
The basis for the classification of the
Mineral Resources into varying
confidence categories.

Whether appropriate account has been
taken of all relevant factors (ie relative
confidence in tonnage/grade
estimations, reliability of input data,
confidence in continuity of geology and
metal values, quality, quantity and
distribution of the data).

Whether the result appropriately
reflects the Competent Person’s view
of the deposit.

The estimate has been classified according to the guidelines
of the JORC Code (2012), into Measured, Indicated and
Inferred Resources taking into account data quality, data
density, geological continuity, grade continuity and confidence
in estimation of heavy mineral content and mineral
assemblage. In plan, polygons were used to define zones of
different classification within each of the mineralised domains.
− Measured Resources are generally defined where
drilling is at 20 m to 40 m on 100 m spaced section lines.
− Indicated Resources are generally defined where drilling
is at 20 m to 40 m by 200 m.
− Inferred Resources are defined where the drill spacing is
up to 80 m by 400 m.
In addition, Inferred Resources are defined for blocks with
HMgrades estimated by the third search.
Audits or
reviews

The results of any audits or reviews of
Mineral Resource estimates.

The Mineral Resource has been reviewed internally as part of
normal validation processes by Optiro.

No external audit or review of the current Mineral Resource
has beenconducted.
Discussion of
relative
accuracy/
confidence

Where appropriate a statement of the
relative accuracy and confidence level
in the Mineral Resource estimate using
an approach or procedure deemed
appropriate by the Competent Person.

The statement should specify whether
it relates to global or local estimates,
and, if local, state the relevant
tonnages, which should be relevant to
technical and economic evaluation.
Documentation should include
assumptions made and the procedures
used.

These statements of relative accuracy
and confidence of the estimate should
be compared with production data,
where available.

The assigned classification of Measured, Indicated and
Inferred reflects the Competent Persons’ assessment of the
accuracy and confidence levels in the Mineral Resource
estimate.

The confidence levels reflect production volumes on a monthly
basis.

No production has occurred from the deposit.
