68% INCREASE IN MINERAL RESOURCES FOR ATLAS PROJECT

_________________

Image Resources NL (ASX: IMA) (“Image” or “the Company”) is pleased to announce a substantial increase of the total tonnes of Mineral Resources for its 100%-owned Atlas Minerals Sand Project located 170 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 Atlas in accordance with the guidelines of the JORC Code (2012). When compared to the Mineral Resource estimate for Atlas prepared for Image in 2011, the total Mineral Resource tonnes have increased by 68%, from 10.8 million to 18.1 million tonnes , albeit at lower heavy mineral (HM) grade and mineral assemblage as detailed below. Total contained HM has increased by 30% to over 1 million tonnes, from previous 840,000 tonnes.

A summary of the Mineral Resource estimate by Optiro for the Atlas deposit as at May 2017, reported at a cut-off grade of 2.0% total HM, is presented in Table 1. The Mineral Resource summary from 2011, reported at a cut-off grade of 2.5% HM is shown in Table 2.

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

  • An expanded area of mineralisation as a result of drilling completed in 2012; and

  • Application of a lower cut-off grade (2.0% HM versus 2.5% in 2011)

Drilling during 2012, within the southern end of the deposit, has extended the strike length of the mineralisation within the main strandline from 5.5 km to 6.5 km and the overall strike length of the mineralisation within all of the strandlines from 7.3 km to 8.3 km. This has added approximately 1.2 million tonnes of Mineral Resources. In general, the additional mineralisation in this extension area within the main strandline (of 0.6 million tonnes) has significantly lower HM grade (5.6% total HM) and a lower overall mineral assemblage value (3.4% zircon) than the previously reported main strandline mineralisation.

Although the expanded Mineral Resource estimate by Optiro is reported as substantially higher tonnes than the 2011 Mineral Resource estimate, it remains to be determined what quantity of these additional tonnes of mineralisation will translate to Ore Reserves.

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. A full copy of the Optiro Mineral Resource estimate summary report is attached.

Increased Mining/Processing Rate

As with the doubling of tonnes of Minerals Resources for the Boonanarring Project (announced to the ASX on 13 January 2017), this substantial increase in tonnes of Mineral Resources at Atlas will allow mining and processing to occur at a higher rate (dry tonnes per hour) than originally envisioned in the Company’s 2013 feasibility study. A higher processing rate serves to increase the economy-of-scale of the project which is beneficial to overall project economics. As an added bonus, the wet concentration plant and associated equipment acquired by Image in June 2016 already has this extra processing capacity (up to 500 dry tonnes ore per hour).

Exploration Upside at Atlas

The increase in tonnes (7.3 million tonnes) of the Mineral Resources is due in large part to the addition of the Atlas south mineralisation extending the mineralised envelop to a total of length of 8.3 km. In addition, there is potential for further extensions of the deposit to the south, based on previous, widespaced drilling. Interpretations of ground magnetic survey data highlights an area extending up to 4 km to the south of Atlas with potential for multiple strands of mineralisation which require further drilling to assess this potential (Figure 1 below). There is a further 10 km of parallel targets in the area which have not been drill tested. Future drilling is being planned to characterise these new targets.

Dear Sir,

ATLAS MINERAL RESOURCE ESTIMATE – MAY 2017

Optiro has prepared an updated Mineral Resource estimate for the Atlas deposit. The Atlas Heavy Minerals Sands deposit is located in the North Perth Basin, Western Australia, approximately 170 km north of Perth.

Mineral Resource Summary

Image Resources NL (Image) prepared a Base Case Feasibility Study to assess the viability of mining and processing mineral sands from its Atlas deposit, using a Mineral Resource estimate prepared in 2011 that was classified in accordance with the guidelines of the JORC Code (2004). Optiro’s updated Mineral Resource, as of April 2017, incorporates results from an additional 241 drillholes (for a total 4,681.5 m) drilled by Image during 2012 and an additional 15 composite samples that were analysed to determine the heavy mineral (HM) assemblage components. The 2017 Mineral Resource comprises data from 2,307 vertical reverse circulation (aircore) drillholes, for a total of 32,300.4 m. A total of 15,854 samples, over a total of 18,760.5 m, have been assayed. Within the interpreted strandline mineralisation the drillhole 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 50 m across strike and 300 m along strike.

The Atlas 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. The strandline mineralisation was interpreted within the Yoganup Formation using a nominal cut-off grade of 2% total heavy minerals. The heavy minerals within the Yoganup Formation have been concentrated in a main strandline which is continuous over a north-south strike length of 6.5 km and which has an across-strike width of up to 500 m. The main strandline mineralisation extends from surface to 16 m depth. It has an average thickness of 3.5 m and a maximum thickness of 12 m. Seven additional zones of strandline mineralisation have been identified to the east, west and north of the main strandline. These additional strandlines are narrower and are not as continuous along strike as the main strandline. They are oriented north-south and their strike lengths range from 0.5 km to 2.5 km. The tops of the additional

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

==> picture [104 x 45] intentionally omitted <==

strandlines range in depth from surface to 4 m and the mineralisation extends to depth of up to 22 m, with an average thickness that ranges from 1.3 m to 4 m.

The majority of samples (95%) are from intervals of 1 m and Image collected samples of ~1.25 kg for each 1 m down-hole interval. Almost 60% of samples have been analysed for total HM, slimes and oversize. Samples were analysed for total HM content by heavy media separation. Almost 97% of the assayed intervals have been analysed using a <63 µm grain size for slimes and a -1mm+63 µm grain size for total HM.

Approximately 3% of the total HM data is from a grain size fraction of -2mm+53 µm. Grain size analysis was used to generate adjustment factors that have been applied to convert the +53 µm total HM data to +63 µm total HM data.

The Mineral Resource includes the results of 65 composite samples (from 326 drillholes totalling 1,168 m) which were analysed to determine the heavy mineral assemblage. The majority of the mineral assemblage data (over 98%) is from QEMSCAN analysis. The QEMSCAN rules for the titanium mineral determination are ilmenite - 50-70% TiO2; leucoxene - 70-95% TiO2, and rutile - >95% TiO2. Mineral assemblage data from one composite sample analysed by grain counting, from within the northern area of the main strandline, has also been used.

Total heavy minerals, 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 inverse distance (squared) techniques.

Bulk density was determined using a formula supplied by Image and adjusted by Optiro following calibration of the formula with density data from Image’s Boonanarring deposit (also in the North Perth Basin). The formula is based upon heavy mineral and slimes percentage concentrations and includes assumptions about void space and mineral densities.

The resource 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. Within the main strandline the majority of the drilling is at 10 m to 25 m on 50 m to 150 m spaced section lines and Measured Resources have been defined where the mineral assemblage data is from QEMSCAN analysis. Indicated Resources have been defined within a small area within the northern area of the strandline where the mineral assemblage the mineral assemblage data is from grain counting analysis. Within the less continuous additional strandlines Indicated Resources have been defined where the majority of the drilling is at 25 m to 40 m on 50 m to 300 m spaced section lines and mineral assemblage data is available. Inferred Resources have been defined within areas where there is limited or no mineral assemblage data.

The Mineral Resource estimate for the Atlas 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 the 2017 Pre-Feasibility Studies. The Mineral Resource is reported for the main strandline and the additional strandlines and for a range of total heavy minerals cut-off grades in Table 2.

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.

The table below summaries the assessment and reporting criteria used for the Atlas deposit Mineral Resource estimates 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
Public Report.
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 1 m, 1.5 m and 2 m. Single
isolated intervals of 0.2 to 0.5 m have been used. Around 74%
of the samples are from 1m, 6% are from 1.5 m and 20% are
from 2 m intervals.
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 drillholes are drilled vertically using an NQ-sized
(76 mm diameter) drill bit.
 All Iluka RCAC drillholes 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.
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 or 2 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
total sample.
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 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 to Image’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% total HM (by weight) are despatched for analysis
along with the intervals above and below the mineralised
interval.
 The level and detail of loggingis of sufficientqualityto support

P a g e | 9

==> picture [104 x 45] intentionally omitted <==

Mineral Resource estimates (MRE).
 All(100%)of the drillingis logged.
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.
 Approximately 60% of samples were analysed for total heavy
minerals (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 two 25 cm by 35 cm
calico bags (as the laboratory despatch and reject samples. The
rotary splitter directs10 increments from the stream to the
laboratory despatch samples, for a specified sampling interval.
 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 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 quality control
ensures no 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 of mineral
sands explorers in the Perth Basin region.
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 (eg standards, blanks, duplicates,
external laboratory checks) and whether
acceptable levels of accuracy (ie lack of
bias) and precision have been established.
 Image and Iluka used industry standard approaches to
estimating the contents of HM, slimes and oversize involving
washing slimes from samples, then extracting the heavy
minerals from the residual sands using heavy media.
 Image engaged two laboratories (Western GeoLabs and
Diamantina Laboratory).
 Image inserted CRMs for assaying undertaken in 2016.
 Both Iluka and Image collected duplicate samples, including
field duplicates of the primary sample and laboratory duplicates
at the laboratory sub sampling stage (post de-sliming).
 Analysis of QAQC data for the drilling programs indicates that it
is of moderate to high quality and supports resource estimation.
 Three sets of mineral assemblage data (two sets of QEMSCAN
data and grain counting data) have been used to estimate the
ilmenite, leucoxene, rutile and zircon concentrations within the
total HM.
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 collected primary data on hard copy logs and also using a
data logger. Data from laboratories was provided in digital form
and compiled in Microsoft Access databases and spreadsheets.
 Approximately 97% of the assayed intervals have been analysed
using a 63 µm sieve and almost 3% of the data having been
analysed using a 53 µm sieve.
 In 2017, 28 samples of -2mm+53 µm HMC were screened at
63 µm to assess the total HM in the -63 µm fraction. This data
was used to determine an adjustment factor to derive estimates
of the % total HM within the -63 μm fraction from the % total
HM within the -53 μm fraction for samples where the % total
HM from the -63 μm fraction was not available.

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.
Specification of the grid system used.
Quality and adequacy of topographic
control.
 Drillhole collars at Atlas 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 MRE have been adjusted to a LiDAR
topographic model described below.
 Data for Atlas has been surveyed in MGA Zone 50 GDA94. The
mineral resource has been estimated in the same coordinate
system due to the north-south trending nature of Atlas. The
topographic model for Atlas is based on LiDAR survey. A review
of this survey by Image did not produce any significant variation
in the resource.
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 drillhole 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
2,307 drillholes for a total 32,300.35 m drilled by Image, TiWest,
RGC and Iluka between 1989 and 2012.
 Samples for HM assemblage determination were composited on
intervals according to a combination of grade and geology
appropriate to reflect resource estimation domains.
 65 composites from 326 drillholes totalling 1,168 m were used
in the 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 drillholes 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 loggingof significant intercepts.

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 Atlas deposit is within pending mining lease M70/1305
(application 17/01/2012; exploration licences E70/2636
(expiry 19/02/2018), E70/2898 (expiry 13/11/2017), E70/3997
(expiry 10/10/2017) and prospecting licence P70/1516 (expiry
27/05/2017). Image has a 100% interest in each of these
licences.
Exploration
done by other
parties
Acknowledgment and appraisal of
exploration by other parties.
 The Atlas deposit was discovered by RGC, which drilled out the
deposit to an Inferred Resource Status. The work is well
documented in reports from Iluka, and prior Mineral Resource
estimator Widenbar and Associates(2011).
Geology Deposit type, geological setting and style
of mineralisation.
 Atlas is hosted in the Perth Basin, in surficial marine sediments
eroded into Cretaceous basal sediments during the Pleistocene
marine transgressions.
 The host sediments consist of unconsolidated well sorted sands
and clayey sands, sitting over basal sediments of very fine to
granular or pebbly, poorly sorted sands and clayey sands.
 Atlas has one major strandline of heavy minerals, with 7 minor
strandlines interpreted to the north, east and west.
 The basement to the strandline mineralisation is identified by
the decrease in mineralisation.
Drillhole
information
A summary of all information material to
the understanding of the exploration
results including a tabulation of the
following information for all Material
drillholes:
o easting and northing of the drillhole
collar
o elevation or RL (Reduced Level –
elevation above sea level in metres) of
the drillhole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
 Not relevant – Mineral Resource defined. Exploration results are
not being reported for the Mineral Resource area.
Data
aggregation
methods
In reporting Exploration Results,
weighting averaging techniques,
maximum and/or minimum grade
truncations (eg 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.
 Not relevant – Mineral Resource defined. Exploration results are
not being reported for the Mineral Resource area.
 There are no metal equivalent values assumptions applied in
the Mineral Resource reporting.

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 drillhole angle is
known, its nature should be reported.
 The geometry of the Atlas mineralisation is effectively
horizontal and the vertical drillholes used to define the Mineral
Resource give the approximate true thicknesses of
mineralisation.
Diagrams Appropriate maps and sections and
tabulations of intercepts should be
included for any significant discovery
being reported
 Refer to figures in report.
Balanced
reporting
Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and
high grades and/or widths should be
practiced to avoid misleading reporting
of Exploration Results.
 Not relevant – Mineral Resource defined. Exploration results are
not being reported for the Mineral Resource area.
Other
substantive
exploration
data
Other exploration data, if meaningful
and material, should be reported
including (but not limited to): geological
observations; geophysical survey results;
geochemical survey results; bulk samples
– size and method of treatment;
metallurgical test results; bulk density,
groundwater, geotechnical and rock
characteristics; potential deleterious or
contaminating substances.
 Slimes and HM grain size analysis reported under “Verification
of sampling and assaying”.
Further work The nature and scale of planned further
work (eg tests for lateral extensions or
depth extensions or large-scale step-out
drilling).
Diagrams clearly highlighting the areas
of possible extensions, including the
main geological interpretations and
future drilling areas, provided this
information is not commercially
sensitive.
 Image is planning infill drilling to allow a likely upgrade of the
northern Indicated part of the resource to Measured. Image is
also planning an extensional exploration programme to the
north of Atlas.

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 drillhole database is managed by Image. Maintenance of
the database includes internal data validation protocols by
Image.
 For the Mineral Resource estimate the drillhole data was
extracted directly from Image’s Micromine 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)
has not visited the Atlas deposit. She has visited other mineral
sands deposits and operations within the North Perth Basin.
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 andgeology. _
 The Yoganup Formation was defined using a combination of
slimes and oversize data and drillhole lithological logs.
 For the purposes of resource estimation, this unit was used in
combination with grade criteria (nominal cut-off grade of 2%
total HM) to define a main strandline and seven additional
strandlines to the north, west and east of the main strandline.
 There is good confidence in the geological interpretation of the
main strandline. Confidence in the other strandlines is lower, as
reflected 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 6.5 km north/south and has an
across strike width of up to 500 m. The strandline mineralisation
extends from surface to 16 m depth.
 Seven additional zones of strandline mineralisation have been
interpreted to the north, east and west of the main strandline.
Strike lengths range from 0.5 km to 2.5 km and they extend
from surface to depth of 22 m.
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 _
 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 a
threshold of ~ 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.
 Drillhole sample data was flagged from the three dimensional
interpretation of the mineralised horizons.
 Samples are from intervals of 0.2 m, 0.25 m, 0.3 m, 0.5 m 1 m,
1.5 m and 2 m. As the majority of samples within the
interpreted mineralisation (82%) 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.
 Total HM, slimes and oversize quantities were estimated using
ordinarykriging (OK)into blocks of 10 mE by50 mN by1 mRL.

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 drillhole data, and use of
reconciliation data if available.
 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 the volume of the strandlines and sub-cells to
minimum dimension of 1.25 mE by 6.25 mN by 0.25 mRL were
used for definition of the 0.5 m soil horizon.
 The drillhole 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.
 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 to have an along strike range of 390 m and an across
strike range of 40 m within the main strandline. Within the
other mineralised strandlines HM mineralisation has an along
strike range of 485 m and an across strike ranges of 40 m.
 The VHM continuity was interpreted from variogram analyses to
have an along strike range of 1,280 m and an across strike range
of 240 m.
 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 two
times the initial search and the third search was up to five times
the initial search with reduced sample numbers. The majority of
blocks (76%) were estimated in the first pass, 23% in the second
pass and 1.4% in the third pass.
 The HM, slimes and oversize estimated block model grades
were visually validated against the input drillhole data and
comparisons were carried out against the declustered drillhole
data and by northing, easting and elevation slices.
 The VHM estimated block model grades were visually validated
against the input drillhole data and comparisons were carried
out against the drillhole data and bynorthingand eastingslices.
Moisture Whether the tonnages are estimated on
a dry basis or with natural moisture, and
the method of determination of the
moisture content.
 Tonnages have been 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 Atlas deposit has been
reported at a 2.0% total HM cut-off. This cut-off grade was
selected by Image based on technical and economic assessment
carried out duringFeasibilityStudies.
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
programmes:
 Grain counting data (1 composite)
 QEMSCAN data from Bureau Veritas (47 composites)
 QEMSCAN data from SGS (17 composites).
 The QEMSCAN rules for the titanium mineral determination are
as follows:
 Ilmenite: 50-70% TiO2
 Leucoxene: 70-95% TiO2
 Rutile: >95% TiO2
 Image considers there are no metallurgical factors which are
likely to affect the assumption that the deposit has reasonable
prospects for eventual economic 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.
 Image is intending to complete environmental studies at Atlas.
At present Image considers there are no environmental factors
which are likely to affect the assumption that the deposit has
reasonable prospects for eventual economic extraction.
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.
 Previous resource estimates (2008, 2009 and 2011) used bulk
density values predicted from an industry-standard formula
which accounts for the total HM and slimes content of heavy
mineral sand deposits.
 Bulk density testwork at Image’s Boonanarring deposit found
that this formula overstated the bulk density. The formula was
calibrated with the 2016 data at Boonanarring and the updated
formula was used for estimation of the bulk density for the
2017 Atlas 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 defined within the main
strandline where drilling is at 10 m to 20 m on 100 m to
150 m spaced section lines and mineral assemblage data
is from QEMSCAN analysis.
 Indicated Resources are defined within the main
strandline where the mineral assemblage has been
estimated from grain counting data and within the
additional strandlines where drilling is generally at 20 m
to 40 m by 200 m and where there is mineral
assemblage data.
 Inferred Resources are defined where there is limited or
no mineral assemblage data.
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
been conducted.
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.
