OPHTHALMIA RESOURCE UPGRADE TO 341 MT GRADING 59.3%Fe

Brockman is pleased to announce a 22.3% and 13.8% increase in Mineral Resource for the Coondiner and Kalgan Creek deposits, respectively to 158 Mt and 59 Mt, grading 58.4% Fe and 59.4% Fe respectively, at the Ophthalmia Iron Ore Project near Newman in the East Pilbara region of Western Australia. This takes the total Mineral Resource Estimate for Ophthalmia to 341 Mt grading 59.3% Fe.

Brockman is progressing a Pre-Feasibility Study for a 15 Mtpa DSO mining operation at Ophthalmia, predicated on the Company achieving a rail infrastructure solution for the Marillana Project, located 80 km northwest of Ophthalmia.

Brockman Mining Limited (Brockman) is pleased to announce an upgraded Mineral Resource of 158 Mt grading 58.4% Fe for the Coondiner Deposits and an upgraded Mineral Resource of 59 Mt grading 59.4% Fe for the Kalgan Creek Deposit. Both areas form part of the Ophthalmia Iron Ore Project, which is located about 15 km north of the Newman township in Western Australia (Figure 1). This represents an overall increase of 36 Mt over the previously announced Mineral Resource but significantly 280 Mt (82%) of the total resource is now classified as Indicated Resources, whereas the previous resource for Ophthalmia contained Indicated Resources of 200 Mt (66%). The average grade of mineralisation has remained nearly identical at 59.3% Fe.

The upgraded Mineral Resource for the Coondiner and Kalgan Creek Deposits were estimated by Golder Associates Pty Ltd (Golder). It has incorporated the results of an additional 193 infill and extension RC drill holes (13,627 m) completed in 2013 and 2014 since the original Mineral Resource estimates were announced. The resource estimate was classified in accordance with guidelines provided in the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code, 2012). The classification was based principally on geological confidence, drill hole spacing and grade continuity from available drilling data and the performance of the grade

interpolation (see Figures 2 and 3). The mineralisation models and block reporting cut-off grades used in the in situ resource estimates are both 54% Fe. The methodology and procedures used for the Mineral Resource estimate, as well as the sampling techniques and data acquisition methods are provided in the attached Mineral Resource statement by Golder Associates Pty Ltd (Appendix 1).

Together with the previously announced Mineral Resources for the Sirius Deposit released to the ASX on 10 March 2014, the total DSO Mineral Resources at the Ophthalmia Project now stand at 341 Mt grading 59.3% Fe (Table 1), of which 280 Mt is classified as Indicated Resources.

During the Mineral Resources estimation process, Exploration Targets ranging from 31 Mt to 50 Mt were identified for Coondiner and Kalgan Creek. The potential quantity and grade of the Exploration Targets are conceptual in nature and insufficient exploration has been completed to allow estimation of a Mineral Resource. Further, it is uncertain if additional exploration will result in the estimation of a Mineral Resource for the Exploration Targets.

The Exploration Targets (Table 2) were based on extrapolated estimates which have insufficient geological confidence and drill hole data to be classified as Mineral Resources. Refer Figures 2 and 3 which show the location of the Exploration Targets with respect to the drilling and Mineral Resources. Brockman Mining will conduct additional exploration and infill drilling to test these targets to further increase the Mineral Resource inventory at Ophthalmia to meet the requirement of mine development schedule.

MINERAL RESOURCE STATEMENT FOR COONDINER AND KALGAN CREEK, WESTERN AUSTRALIA

Dear Colin

At the request of Brockman Mining Australia Pty Ltd (Brockman Mining), Golder Associates Pty Ltd (Golder) has updated the Mineral Resource estimate for the Coondiner and Kalgan Creek deposits, which are part of Brockman Mining’s Ophthalmia Project.

The Mineral Resource estimate was classified in accordance with guidelines provided in the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code, 2012 Edition). The classification was based principally on geological confidence, drill hole spacing and grade continuity from available drilling data and the performance of the grade interpolation.

The in situ Mineral Resources for Coondiner and Kalgan Creek are shown in Table 1 and Table 2 respectively. The in situ Mineral Resources are reported at a 54% Fe cut-off grade. Coondiner is subdivided into five main areas, Pallas, Castor, Top Forge, Crucible and Three Pools East. Kalgan Creek includes three main areas: the main, east and south zones. Mineral Resources have been classified for Pallas and Castor at Coondiner and for the three main areas at Kalgan Creek.

Assumptions and Methodology

This Mineral Resource estimate for the Coondiner and Kalgan Creek prospects is based on a number of factors and assumptions:

  • The Coondiner and Kalgan Creek mineralisation is hosted within the Boolgeeda Iron Formation, which is composed of predominantly banded iron formation (BIF) units intercalated with minor mudstone, siltstone and chert units. The Boolgeeda Iron Formation sits conformably above the Woongarra Rhyolite. During the Tertiary period these rocks were overlain by alluvial and colluvial sediments derived from cyclic weathering and erosion of the surrounding BIF (Figure 1).

  • All of the available reverse circulation and diamond drilling data as of 18 August 2014 was used for the Coondiner Mineral Resource estimate and all of the available drilling data as of 3 September 2014 was used for the Kalgan Creek Mineral Resource estimate. This data was collected by Brockman Mining from its 2011 to 2014 drilling campaigns.

  • The collar positions were surveyed using a differential global positioning system, and are considered adequate for the purposes of this Mineral Resource estimate.

  • Downhole deviation surveys have been completed for 31% of the drill holes at Coondiner and 34% of the drill holes at Kalgan Creek. The downhole surveys show deviations of less than 5 m at the end of the deepest drill holes when compared to the vertical set-up of the hole. Potential downhole deviations for drill holes without downhole survey information are unlikely to have a material impact on the Mineral Resources.

  • Sub-sampling and sample preparation were performed by Nagrom Laboratory in Perth. All samples submitted to Nagrom were assayed for Fe, SiO2, Al2O3, TiO2, MnO, CaO, P, S, MgO, and K2O by X-ray fluorescence (XRF) and for loss on ignition (LOI) at 1000°C by thermogravimetric analysis (TGA).

  • A review of the quality assurance and quality control (QAQC) data was completed by Golder. The QAQC program included company standards, blanks and field duplicates submitted at a rate of 1 in 25 of all assayed samples. Analysis of the QAQC data indicates that drill hole samples were prepared and analysed with acceptable quality for this Mineral Resource estimate.

  • Mineralisation domains were interpreted on paper sections and modelled as three dimensional wireframes by Brockman Mining. A mineralisation cut-off grade of 54% Fe was used to define the mineralised domain.

  • Statistical and geostatistical analyses were carried out on drilling data composited to 2 m downhole intervals. This included variography to model the spatial continuity of the grades within each domain.

  • Grade interpolation was completed using Ordinary Kriging for the estimation of Fe, SiO2, Al2O3, CaO, P, LOI, S, MnO, TiO2, K2O and MgO and variogram parameters defined from the geostatistical analysis.

  • A global in situ density of 2.6 t/m[3] was assigned to the Coondiner and Kalgan Creek mineralisation. The density determinations were based on data collected from calibrated downhole probe.

  • The classification of Mineral Resources was completed by Golder geologists. The classification was based principally on geological confidence, drill hole spacing and grade continuity from available drilling data and the performance of the grade interpolation.

  • The in situ Mineral Resource is constrained to the mineralisation domain boundaries within tenements E47/1598, E47/2280 and E47/2291 for Coondiner (Figure 2) and E47/1599 for Kalgan Creek (Figure 3).

Exploration Target

During the Mineral Resource estimation process, Exploration Targets were identified for Coondiner and Kalgan Creek. The potential quantity and grade of the Exploration Targets is conceptual in nature and insufficient exploration has been completed to allow estimation of a Mineral Resource. Further, it is uncertain if additional exploration will result in the estimation of a Mineral Resource for the Exploration Targets described in this statement.

The Exploration Targets were based on extrapolated estimates which have insufficient geological confidence and drill hole data to be classified as Mineral Resources. Figure 2 and Figure 3 show the location of the Exploration Targets with respect to the drilling and Mineral Resources.

Brockman Mining will conduct additional infill and exploration drilling to test these targets and to further increase the Mineral Resource inventory at Ophthalmia which is currently a subject of a Pre-feasibility Study.

The Exploration Targets for Coondiner and Kalgan Creek are summarised in Table 3.

The JORC Code Assessment Criteria

The JORC Code (2012) describes a number of criteria, which must be addressed in the Public Report of Mineral Resource estimates for significant projects. These criteria provide a means of assessing whether or not parts of or the entire data inventory used in the estimate are adequate for that purpose. The resource estimate stated in this document was based on the criteria set out in Table 1 of that Code. These criteria are discussed as follows.

Section 1: Sampling Techniques and Data

Sampling Techniques (Brockman
Mining)
Sampling of Reverse Circulation (RC) chips and diamond cores
was carried out in accordance to Brockman Mining’s sampling
protocol and QAQC procedure, conforming to the industry best
practices.
Two sub-samples (A- and B- series split samples) of RC chips,
each weighing mostly between 1.5 kg and 4 kg, were collected at
2 m intervals via a cone splitter mounted on the drill rig into
pre-numbered calico bags. The A-series split samples were
submitted for routine analysis, whereas the B-series split samples
were reserved at the drill site.
Bulk reject samples were collected at 1 m intervals and were
placed either directly on the ground as piles in orderly rows if the
samples were dry to moist or into pre-numbered polyweave bags
if the samples were wet.
The size of split samples was checked at all times to ensure each
sample satisfied the minimum size/weight (e.g., 1/3 of large
calico bag or 1 kg) required for the sample to be valid for
chemical analysis.
Grab samples were taken directly from the bulk sample piles or
polyweave bags following the sampling technique specified in
Brockman Mining’s sampling procedure in order to take a
representative sample. It was taken when a) the samples were
too wet to split through the cone splitter, or b) the original split
samples were undersize (i.e., less than 1 kg).
The diamond cores prior to 2012 (13 drill holes) were halved
before submitting for assaying, usually at 1 m intervals. The
whole cores from the 2012 diamond core drilling program at
Sirius (8 drill holes) were processed at 2 m intervals as part of a
metallurgical test work program and the head assays were
obtained to check against the assays of the RC holes twinned by
the diamond core holes.
Field duplicates were taken at a rate of one per hole.
Field standards (Certified Reference Materials) with a range of
iron values were inserted every 25thsample.
Nature and quality of sampling (e.g. cut
channels, random chips, or specific
specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
downhole gamma sondes, or handheld
XRF instruments, etc.). These examples
should not be taken as limiting the broad
meaning of sampling.
Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any
measurement tools or systems used.
Aspects of the determination of
mineralisation that are Material to the
Public Report. In cases where ‘industry
standard’ work has been done this would
be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised
to produce a 30 g charge for fire assay’).
In other cases more explanation may be
required, such as where there is coarse
gold that has inherent sampling
problems. Unusual commodities or
mineralisation types (e.g. submarine
nodules) may warrant disclosure of
detailed information.
Drilling Techniques (Brockman
Mining)
RC drilling was completed using standard full-size Hydco 350 rigs
with a 140 mm diameter face-sampling hammer.
Standard wheel-based diamond rigs were used in the diamond
core drilling program with HQ3 drilling methods.
A summary of all drilling types is shown below:
Coondiner:

353 RC holes for a total of 26 202 m. All but 12 holes were
drilled vertically with an average hole depth of 75 m and a
depth range from 7 m to 175 m.

5 diamond holes (HQ3) for a total of 564 m. All were drilled
vertically with an average hole depth of 113 m and a depth
range from 85 m to 145 m.
Drill type (e.g. core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.), and details
(e.g. core diameter, triple or standard
tube, depth of diamond tails,
face-sampling bit or other type, whether
core is oriented and if so, by what
method, etc.).

Sub-Sampling Techniques and
Sample Preparation (Brockman
Mining)
Sub-sampling and sample preparation were performed by
Nagrom Laboratory in Perth.
Sample preparation includes sort, dry (8 to 12 hrs at 105°C)
weigh, split (to 2 kg, reserve retained if required), pulverise (2 to
5 minutes depending on sample through LM5) and split assay
pulp packet (bulk pulp reserve retained).
Lab duplicates were taken at a rate of 1 in 20 samples.
Lab standards were randomly inserted at a rate of 1 in 20
samples.
XRF calibrations are checked every morning using calibration
beads made using exact weights.

Quality of Assay Data and Laboratory
Tests(Brockman Mining)
All samples submitted to Nagrom were assayed for Fe, SiO2,
Al2O3, TiO2, MnO, CaO, P, S, MgO, and K2O by XRF and for LOI
at 1000°C by thermogravimetric analysis (TGA).
Laboratory procedures are in line with ISO9001 Quality
Management System and appropriate for iron ore deposits.
Samples were dried at 105°C, weighed, crushed to a nominal -
6.3 mm size, and then pulverised to 95% passing 75 µm.
A 0.8 g sub-sample was collected and fused in 8 g of 12:22
lithium borate flux with 5% lithium nitrate additive. The resultant
glass bead was analysed by XRF.
Another 1–2 g sub-sample was dried and ignited at 1000°C with
LOI calculated once constant mass was reached. LOI is the
percentage mass change due to igniting the dry sample.
Analysis of field duplicate samples shows that greater than 95%
of pairs have less than 5% difference. Assays of all laboratory
duplicates were within 2.5% of assays of the original samples
repeated.
Assays of all Certified Reference Materials inserted by Brockman
Mining and Nagrom are within the acceptable tolerance limits.
Samples have been sent to an umpire laboratory as an
independent check of the assay results. The results are pending
at the time of this resource statement.

Verification of Sampling and Assaying
(Brockman Mining)
Significant intersections reported have been independently
verified by company geologists.
Seven diamond holes with each twinning an existing RC hole
(within 5 m) were drilled mainly for the purpose of verifying the
assay results of the RC holes. Detailed assessment of the twin
hole assays of has led to the conclusion that the assays of the
RC samples, as a whole, from both deposits are reliable.
Primary data are captured on paper (hard copy logs) as well as
electronically using Toughbook laptops (digital logs) and Ocris
software that has built-in validation routines to prevent data entry
errors.
All field data sent by Brockman Mining’s field geologists during
drilling, as well as assay data from the laboratory were loaded
into a secured SQL database managed by Expedio – a Perth-
based database management company.
All geological and assay data used in the estimate were validated
by Brockman Mining. No adjustments or modifications were
made by Golder during the resource estimation.
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.
Location of Data Points (Brockman
Mining)
All collars were initially surveyed by Brockman Mining personnel
using a hand held GPS, and later by Bore Hole Geophysical
Services using a differential GPS with an nominal horizontal and
vertical accuracy of 150 mm.
Downhole deviation surveys were completed for all holes
completed in the 2013 and 2014 drilling program. This includes
112 out of 358 drill holes at Coondiner and 61 out of 182 drill
holes at Kalgan Creek.
The downhole surveys were conducted by Surtron Technologies
using a conventional magnetic susceptibility tool. The downhole
survey data were validated by Brockman Mining.
The downhole surveys show deviations of less than 5 m at the
end of the deepest drill holes when compared to the vertical set-
up of the hole. Therefore, based on the current drill hole spacing,
potential downhole deviations for drill holes that do not have
downhole surveys are unlikely to have a material impact on the
Mineral Resources.
The grid system for the Ophthalmia Project is MGA GDA94 Zone
50 and the vertical datum is AHD.
The Digital Terrain Model (DTM) used in the estimation was
acquired from Fugro Spatial Solutions with a quoted horizontal
accuracy of 0.6 m and a vertical accuracy of 0.3 m.
Accuracy and quality of surveys used to
locate drill holes (collar and downhole
surveys), trenches, mine workings and
other locations used in Mineral Resource
estimation.
Specification of the grid system used.
Quality and adequacy of topographic
control.

Data Spacing and Distribution
(Brockman Mining)
The nominal drill hole spacing for the Coondiner and Kalgan
Creek is 200 m by 100 m (200 m between sections and 100 m
within each section). Drilling has been completed on 50 m
centres on a limited number of the major cross sections at
Coondiner.
The sample data spacing and distribution were considered
sufficient for each of the Mineral Resource categories classified
under the JORC Code, 2012 Edition.
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.
Orientation of Data in Relation to
Geological Structure (Brockman
Mining)
Lithological units and associated stratabound mineralisation
strike east-southeast and are generally folded about a series of
upright to slightly inclined, open folds.
The drilling is generally perpendicular to the mineralisation, with
the majority of the drill holes being vertical and only one hole at
Kalgan Creek and three holes at Coondiner drilled with a dip of
60°.
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.
Sample Security (Brockman Mining) The chain of custody of all assay samples is managed by
Brockman Mining.
A-series assay samples in calico bags were packed into
polyweave bags and sealed before placed inside heavy-duty
bulka bags during drilling.
Periodically the bulka bags were picked up from site by a local
transport company and deposited with Regal Transport in
Newman, who delivered the samples to the laboratory.
Once received at the laboratory, the samples were sorted and
securely stored until analysis.
No loss or damage of samples has ever occurred during storage
or transit.
The measures taken to ensure sample
security.
Audits and Reviews (Brockman
Mining)
The database is stored in Micromine GBIS data management
system which is maintained by Expedio, contracted by Brockman
Mining. Routine checks and validations were carried out by
Expedio consultants. Brockman Mining has conducted its
internal validation of the database before carrying out the
mineralisation interpretation.
Golder carried out an independent review of the sampling and
QAQC procedures for its initial Mineral Resource estimates in
October 2012 and December 2012 and again as part of this
resource update.
The results of any audits or reviews of
sampling techniques and data.

Comment

Section 3: Estimation and Reporting of Mineral Resources

Database Integrity (Brockman Mining) Database integrity is maintained in the following stages of data
management routine:

Data entry: Digital geology and sampling data are captured
using Ocris which has built-in look-up codes (same as the
ones used in the database) and validation rules to prevent
data entry errors.

Export of primary data: the Ocris logs require validation
before they can be exported as a single Ocris native OXO
file, using built-in functionalities in Ocris.

Import of primary data into the database: the Ocris OXO file
is loaded into the centralised SQL database by Expedio
through an importing routine within GBIS.

Export of secondary data from the database: automated
data-export SQL queries were developed within GBIS and
used for exporting drill hole data for use in Mineral Resource
estimation.
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.
Site Visits(Brockman Mining) Aning Zhang has visited site and inspected the exploration field
operations including logging and sampling processes.
Aning Zhang has also visited Nagrom and inspected the sample
preparation and assaying processes.
Comment on any site visits undertaken
by the Competent Person and the
outcome of those visits.
If no site visits have been undertaken
indicate why this is the case.
Geological Interpretation (Brockman
Mining)
The interpretation of the overall mineralisation model is based on
the geological understanding of both the lithological and
structural controls of mineralisation from the detailed surface
mapping and the substantial amount of exploration drilling to
date. The main BID zones in both deposits occurs in the core of
the localised synclines in the lower part of the Boolgeeda Iron
Formation, similar to the Sirius deposit where significant outcrops
of BID mineralisation are present.
Although the mineralisation genesis of the BID mineralisation
hosted in the Boolgeeda Iron Formation is still poorly understood,
the nature of the mineralisation (friable and entirely within the
weathered to completely oxidised zone) strongly points to a
supergene enrichment origin of the Tertiary period. Any pre-
existing linear structures e.g., the thrust fault and the NE-trending
cross-cutting faults at the Kalgan deposit) will, therefore, not
offset the mineralisation which is post-deformation, but may have
some effect on the mineralisation if unfavourable lithological unit
occurs across the fault due to the juxtaposition of the strata
during the faulting.
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.
Dimensions(Brockman Mining) The maximum extents of the Mineral Resources are as follows:

Pallas:3100 m (strike) by 1100 m (width) by 120 m
(thickness), from 20 m below surface.

Castor:1800 m (strike) by 400 m (width) by 120 m
(thickness), from 30 m below surface.

Kalgan Creek: 3800 m (strike) by 270 m (width) by 100 m
(thickness), from surface.
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.

Estimation and Modelling Techniques
(Golder)
Mineralisation was defined by zones identified from downhole
lithological and geochemical data.
The block sizes are 50 m (X) by 25 m (Y) by 6 m (Z) or
approximately ¼ of the drill hole spacing in the X (east) and Y
(north) directions. The sub-block sizes are 5 m (X) by 5 m (Y) by
2 m (Z).
Using parameters derived from modelled variograms, Ordinary
Kriging (OK) was used to estimate average block grades for Fe,
SiO2, Al2O3, CaO, P, LOI, S, MnO, TiO2, K2O and MgO
Unfolding was used during estimation to enable correlation of
samples around the folded structures.
The estimation was conducted in three passes with the search
size increasing for each pass.
The models were validated visually and statistically using
statistics, swath plots and change or support models.
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. sulfur 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.
Moisture(Golder) All tonnages are based on an assumed_in situ_bulk density, i.e.,
including natural moisture.
Whether the tonnages are estimated on
a dry basis or with natural moisture, and
the method of determination of the
moisture content.

Cut-off Parameters(Golder) The Mineral Resource models are constrained by assumptions
about economic cut-off grades. The mineralisation interpretation
is confined by a 54% Fe cut-off grade. The tabulated resources
are reported using cut-off grade of 54% Fe, applied on a block by
block basis.
The basis of the adopted cut-off grade(s)
or quality parameters applied.
Mining Factors or Assumptions
(Golder)
Golder assumes that the deposits are suitable for open pit
mining, using a 12 m bench with 6 m flitches.
The_in situ_Mineral Resource is reported at a 54% Fe cut-off
grade, which is the same as the cut-off grade that was used for
the interpretation of the mineralisation models that were used to
constrain the estimate. For mine planning purposes, ore loss and
dilution need to be considered.
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.
Where this is the case, this should be
reported with an explanation of the basis
of the mining assumptions made.
Metallurgical Factors or Assumptions No metallurgical testwork has been conducted for Coondiner and
Kalgan Creek deposits. Two findings from the metallurgical
testing to date at the Sirius deposit which has the similar style of
mineralisation (e.g. occurs in the similar part of the Boolgeeda
Iron Formation and friable mineralisation with similar chemical
composition) are as follows:

Uniform chemical composition of mineralisation in all size
fractions and high in phosphorus (typically 0.18%).

Very soft, friable mineralisation, which is likely to require low
energy/power to operate primary and secondary crushing
circuits.
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. Where this
is the case, this should be reported with
an explanation of the basis of the
metallurgical assumptions made.
Environmental Factors or
Assumptions(Brockman Mining)
These aspects have not been considered at this stage but the
very low sulfur assays suggest that acid rock drainage will not be
material issue for waste disposal.
As the project is envisaged to be a direct-shipping operation. It is
expected that there will be minimal process residue which will not
present any issues for disposal.
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. While at this stage the
determination of potential environmental
impacts, particularly for a greenfields
project, may not always be well advanced,
the status of early consideration of these
potential environmental impacts should be
reported. Where these aspects have not
been considered this should be reported
with an explanation of the environmental
assumptions made.

JORC Code Assessment Criteria Comment
Bulk Density (Brockman Mining) Downhole density determinations were completed by Surtron
Technologies Pty Ltd using a calibrated 9138 series multi-
parameter sidewall density probe. This included 184 RC and 5
diamond drill holes at Coondiner and 62 RC drill holes at Kalgan
Creek.
The geophysical results were filtered to remove outlier density
values and other density values associated with outlier caliper
readings. Average densities were then estimated globally and for
each domain.
Following analysis of the estimated densities, a global_in situ_
density of 2.6 t/m3was assigned to the Kalgan Creek and
Coondiner mineralisation.
Attempts have been made in physical determination of the bulk
densities using the diamond cores for the Ophthalmia deposits.
This has proved to be difficult due to the friable nature of the ore.
A total of 192 core samples from 19 diamond holes drilled
between 2011 and 2013, including 12 holes at Sirius and 5 holes
at Coondiner and 2 at Kalgan Creek were selected and tested.
The overall average natural bulk density based on dry bulk
densities and assumed product moisture of 7% is 2.23 t/m3 with
densities for the soft BID ore ranging from 1.60 to 3.55 (t/m3)
averaging 2.17 t/m3. These results are considered as being
inconclusive due to their poor representation and the
uncertainties in the amount of material loss during drilling as well
as the natural moisture content used.
Further investigation and testwork which may involving drilling
large diameter holes for the purpose of both density
determination and metallurgical testwork need to be carried out.
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.
Classification(Golder) Resources were classified in accordance with the JORC Code,
2012 Edition.
The classification of Mineral Resources was completed by Golder
based on geological confidence, drill hole spacing, grade
continuity and the performance of the grade interpolation. The
Competent Person is satisfied that the result appropriately
reflects his view of the deposit.
Continuous zones meeting the following criteria were used to
define the resource class:
Indicated Resource

Drill spacing of 150 m by 50 m and 200 m by 50 m and
some alternate cross sections at Pallas which had drill holes
on 100 m centres.

Evidence of geological and grade continuity.
Inferred Resource

Typical drill spacing of 200 m by 100 m and 200 m by 50 m.

Greater geological complexity, such as changes in
orientation, thickness or grade continuity.

Estimates where the geology or grades are extrapolated
from higher confidence areas.
The basis for the classification of the
Mineral Resources into varying
confidence categories.
Whether appropriate account has been
taken of all relevant factors, i.e. 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.
Audits or Reviews(Golder) This Mineral Resource estimate is an update to the previous
Mineral Resource estimate completed by Golder in October 2012
and December 2012.
