ORE RESERVES UPDATE FOR 100% OWNED ATLAS PROJECT

Image Resources NL (ASX: IMA) (“Image” or “the Company”) is pleased to announce an Ore Reserves update on its 100%-owned Atlas Mineral Sands Project , located in the North Perth Basin, 80 km north of the Company’s Boonanarring project and 170 km north of Perth, Western Australia.

As part of the bankable feasibility study ( BFS ) nearing completion on the Company’s high-grade Boonanarring and Atlas mineral sands projects, Optiro Pty Ltd (Optiro) have completed an update of the estimated Ore Reserves for the Atlas project in accordance with the guidelines of the JORC Code (2012) .

When compared to the Ore Reserves reported in the 2013 feasibility study, the total tonnes of Ore Reserves remained relatively constant at 9.5 million tonnes.

A summary of the estimated Ore Reserves for Atlas as at May 2017, reported on the Mineral Resources at a cut-off grade of 2.0% heavy minerals (HM), is presented in Table 1. The Ore Reserves from the 2013 feasibility study, reported on 2011 Mineral Resources at a cut-off grade of 2.5% HM, is shown in Table 2.

The following are key items addressed in the 2017 Ore Reserve estimate:

  • Estimate in accordance with the guidelines for the reporting of Mineral Resources and Ore Reserves JORC Code (2012);

  • The bulk density formula was adjusted using data from Image’s Boonanarring deposit (located within the Perth Basin and to the south of the Atlas deposit). The formula was adjusted by applying a 6% reduction to the calculated density for material with <28% slimes and assigned density of 1.8 t/m[3] for material with slimes contents of 28% to 50% and 1.54 t/m[3] for material with slimes of >50%;

  • Exclusion zones have been applied to the high voltage powerlines and Wongonderrah Road, which both cross the Atlas Mineral Resource.

The Executive Summary from the Ore Reserves estimate by Optiro is attached.

The Atlas 2017 Ore Reserves have been incorporated into the overall Project BFS. Further review of capital cost estimates and economic modelling is ongoing and BFS reporting is underway and anticipated to be completed during May 2017.

Extract from Image Resources NL Atlas Mineral Sands Deposit Ore Reserves Report - May 2017

EXECUTIVE SUMMARY

Optiro Pty Ltd (Optiro) was commissioned by Image Resources Limited (Image) to oversee the Ore Reserve estimation process for the Atlas Project as at 1 May 2017. The Atlas project is located approximately 170 km north of Perth and 18 km east of the coastal town of Cervantes. The orebody lies 1.4 km east of the Nambung National Park, (better known for “the Pinnacles”), approximately 90 km from Images Boonanarring Minerals Sands project.

The Ore Reserve estimate followed the creation of an open pit Mineral Resource estimate in May 2017 as part of the Mineral Resource update for the Atlas mineral sands project. The Mineral Resources work was carried out by Christine Standing (Principal Consultant, Optiro) a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves' (the JORC Code).

All material was subjected to an economic evaluation, wherein all costs have been based on a mining rate of 3.3 Mtpa, a wet concentrator plant throughput rate of 3.3 Mtpa and process recoveries of 92% for ilmenite, 74% for leucoxene, 92% for rutile and 93% for zircon. Further dry plant processing is to be undertaken (by others) with a projected average throughput of 240,000 tonnes heavy mineral concentrate (HMC) per annum with recoveries of 94% ilmenite, 75% leucoxene, 94% rutile and 88% zircon.

The Atlas Project is to be operated using conventional heavy mineral sands open pit mining methods (excavators, trucks, scrapers, mobile hoppers, dozers and grader) by a mining contractor on a schedule of rates style contract. Dilution and recovery of the ore zones were estimated at 2% and 100% respectively. These parameters were agreed to in consultation with Image.

Revenue was based on an AUD:USD exchange rate of 0.73; an ilmenite price of $171 per tonne, leucoxene price of $522 per tonne, rutile price of $936 per tonne and a zircon price of $1,126 per tonne. All prices are in $US.

To the best of Optiro’s knowledge, Image is currently compliant with all legal and regulatory requirements. A gap analysis has been undertaken to quantify what needs to be completed for government permits, licenses and statutory approvals. All approvals for the Atlas project are expected to be obtained within 2-3 years of formally commencing the environmental approval process. No risk factors have been applied to the mining rates.

Measured and Indicated Mineral Resources were converted to Probable Ore Reserves, subject to the mine design, physical modifying factors and an economic evaluation. Measured Mineral Resources were converted to probable due to the requirement of more test work to be completed on the density component of the ore body. The following Ore Reserve statement outlines the Ore Reserves for the Atlas Project as at May 2017.

Material was excised (~8.6 Mt) from the Mineral Resource model used to generate the Ore Reserve model. This material was excluded from the following areas:

  1. Inferred material.

  2. Standoff from roads (50 m, Wongonderrah Road) a total of 1.5 Ha of land and 42,000 t of ore.

  3. Standoff from HV powerlines (50 m) a total of 1.2 Ha of land and 70,000 t of ore.

APPENDIX A. JORC CODE TABLE 1 CRITERIA

The table below summaries the assessment and reporting criteria used for the Atlas Project Mineral Resource and Ore Reserve 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

SECTION 1 SAMPLING TECHNIQUES AND DATA SECTION 1 SAMPLING TECHNIQUES AND DATA SECTION 1 SAMPLING TECHNIQUES AND DATA
(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling. 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. 74% of the samples are from
1 m, 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 backto the originaltotalsample.
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 logging is of sufficient quality to support Mineral
Resource estimates (MRE).
•All(100%) ofthe drillingislogged.
Sub-sampling

•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

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.
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
explorersinthePerth 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+53µm HMC were screened at 63 µm to
assess the total HM in the -63µm fraction. This data was used to
determine an adjustment factor to derive estimates of the % total HM
within the -63μm fraction from the % total HM within the -53μm fraction
for samples where the % total HM from the -63μm 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 significantvariationoftheresource.
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
estimationprocedure(s) and classifications
•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.
• Samplesfor HMassemblage 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
estimationprocedure and classificationapplied.
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
usingImages checking and quality controlprocedures.
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.

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

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 validationprocedures 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)validationprotocols, andvisuallyinplanand 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 operationswithintheNorth 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
_and geology. _
•The Yoganup Formations 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
depthof 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 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.
•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 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 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 boundarieswere applied to the estimationof 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 bynorthing 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 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 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 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
eventualeconomic 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

eventual economic extraction to consider the
potential environmental impacts of the
mining and processing operation.
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
mineralassemblage 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.

Study status
The type and level of study undertaken to
enable Mineral Resources to be converted to
Ore Reserves.

Pre-Feasibility Study level has been
undertaken to convert Mineral Resources to
Ore Reserves. Such studies will have been
carried out and will have determined a mine
plan that is technically achievable and
economically viable, and that material
Modifying Factors have been considered.

Image completed a Pre-feasibility study in 2013
Cut-off
parameters

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

The cut-off grade in the case of Atlas has been calculated using
spreadsheets and an individual cut-off grade applied to each block within
the model. The calculations consider, among other considerations,
individual mineral and product values, operating costs and other practical
considerations (including ore and overburden variabilities) and HM and
product recoveries.
Mining
factors or
assumptions

The method and assumptions used as
reported in the Pre-Feasibility or Feasibility
Study to convert the Mineral Resource to an
Ore Reserve (i.e. either by application of
appropriate factors by optimisation or by
preliminary or detailed design).

The choice, nature and appropriateness of
the selected mining method(s) and other
mining parameters including associated
design issues such as pre-strip, access, etc.

The assumptions made regarding
geotechnical parameters (eg pit slopes,
stope sizes, etc), grade control and pre-
production drilling.

The major assumptions made and Mineral
Resource model used for pit and stope
optimisation (if appropriate).

The mining dilution factors used.

The mining recovery factors used.

Any minimum mining widths used.

The manner in which Inferred Mineral
Resources are utilised in mining studies and
the sensitivity of the outcome to their
inclusion.

The infrastructure requirements of the
selected mining methods.

The truck, shovel and scrapers method has been chosen for the mining
of the Atlas Project. The truck, shovel and scraper method is used in
similar operations in Australia. Appropriate factors have been applied to
the Mineral Resource by optimisation and design to derive the Ore
Reserves.

The choice of the truck, shovel and scraper method was deemed
appropriate due to the ore thickness, access, and nature of the geology.
Similar mining methods were also used in the geographical area, such
as Iluka’s Gingin deposit

A preliminary study by Golder Associates was undertaken in 2010,
however this was only one drill hole. Recommendations were made for
35 degrees. Further testwork will be conducted

Mining dilution (2%) and recovery factors (100%) are assumptions made
for similar mining operations and mining techniques. Reconciliations
from previous operations to date have supported these assumptions.

Grade control will be conducted by a geologist in pit using panning to
establish ore contacts, in conjunction with Survey who also be used to
stake our ore surfaces.

Inferred resources were not used in the Ore Reserve output. However
will be used in an operations schedule for internal production purposes.

Infrastructure required will be office blocks, mining contractor workshop
and associated facilities.
Metallurgical
factors or
assumptions

The metallurgical process proposed and the
appropriateness of that process to the style
of mineralisation.

Whether the metallurgical process is well-
tested technology or novel in nature.

The nature, amount and representativeness
of metallurgical test work undertaken, the
nature of the metallurgical domaining applied
and the corresponding metallurgical
recovery factors applied.

Any assumptions or allowances made for
deleterious elements.

The existence of any bulk sample or pilot
scale test work and the degree to which
such samples are considered representative

The ore is processed through a wet concentration plant (WCP) to
produce a Heavy Mineral Concentrate (HMC) which is further processed
at an offsite Mineral Separation Plant (MSP) to generate final products.
The WCP and MSP use traditional mineral sands separation techniques.
The metallurgical process and appropriateness of the process is outlined
in a process map by Image and is detailed in the Ore Reserve
document. The process has been widely utilised in similar operations.

The metallurgical process is well tested and commonly used in similar
operations worldwide.

Deleterious materials include oversize material and clay fines which will
be managed as part of Image’s rehabilitation management plan and
mildly radioactive material, which will be returned into the pit as backfill
and capped.
