Reward Resource and Feasibility
Study Update
----- End of picture text -----

10 January 2022

  • Reward mineral resource estimate updated

  • 20% increase in contained copper metal to 244 kt

  • Grade consistent at 1.80% copper

  • Two new higher-grade shoots defined

  • Indicated category mineral resource tonnes up 23%

  • Basis for feasibility study’s revised mine plan

  • Feasibility Study now scheduled for mid-2022

KGL Resources ( ASX:KGL ) is pleased to announce an update of the mineral resource estimate for the Reward deposit. The Reward deposit hosts one of the three principal mineral resources which comprise the Jervois Copper Project and has been subject to a significant program of resource-growth drilling during 2021. Mineral resource estimate updates for the other two deposits, Bellbird and Rockface, are underway and together they will underpin feasibility study updated mine plans. Taking into consideration this resource update and the expected updates on Bellbird and Rockface, along with COVID-19 restrictions and industry wide challenges, the Feasibility Study is now scheduled for delivery in mid-2022.

Reward Resource Update

The mineral resource estimate was completed by experienced and independent consultants, Mining Associates Pty Ltd, and their summary report is included as part of this announcement. The mineral resource estimate incorporated the results from drilling during 2021 along with drilling results from earlier times. The estimate is reported according to the JORC (2012) guidelines.

Results

When compared to the most recent previous estimate (2020), the Reward mineral resource estimate delivers a 20% increase in contained copper metal, to 244 kt, and 20% increase in resource tonnes to 13.58 Mt, in the indicated and inferred categories. Copper grade remains consistent at 1.80%. Table 1 below presents the latest mineral resource parameters and Figure 1 show the progression of copper results from the past four Reward mineral resource estimates.

  • does not include Reward South deposit

  • Due to rounding to appropriate significant figures, minor discrepancies may occur, tonnages are dry metric tonnes.

Mineral resources are not ore reserves and do not have demonstrated economic viability.

Inferred resources have less geological confidence than indicated resources and should not have modifying factors applied to them. It is reasonable to expect that with further exploration most of the inferred resources could be upgraded to indicated resources.

Reward Resource and Feasibility
Study Update

KGL Managing Director Simon Finnis comments: “While we have experienced delays in the resource work after we were unable to drill in 2020 due to COVID-19, which has subsequently delayed the Feasibility Study, a 20% increase in the Reward mineral resource is an important result for KGL. This increase has been achieved by carefully planned resource growth drilling, largely within the known footprint of the Reward deposit.

“Two new higher-grade shoots have been defined (Main FW and Main HW) located within a previously modelled lower-grade gap between Main shoot and Deeps South shoot (see long section in Figure 4). Importantly this newly defined mineralisation should be readily accessible for mining from the Reward decline and therefore make an important early contribution to production.

“Mineral resources for Bellbird and Rockface are currently being estimated, although this work is being hampered by slow assay lab turn-around times for the final set of Rockface drill holes.”

Feasibility Study

KGL Resources Limited had expected the Jervois Feasibility Study would be complete in Q1 2022, however industry-wide challenges including Covid-19 related restrictions impacting site activities has led to a delay in completing the Jervois mineral resource and ore reserve updates, subsequent finalisation of the optimised mine plan and, therefore, the completion of the Feasibility Study itself. Bellbird resource update should be completed in early 2022, and it will be a number of months before Rockface will be complete.

Whilst the delay to mid-2022 is disappointing, it will allow KGL to:

  • include recent Rockface results in the mineral resource update;

  • add to mineral resources, most likely at Reward and Rockface based on recent drilling;

  • further optimise the mine plan;

  • finalise offtake arrangements;

  • identify and define any cost pressures to refine capital and operating costs, and;

  • continue to explore optimal project financing options, including the potential for Government assistance (NAIF), and develop an appropriate funding strategy.

The clear benefit of this additional time will be the likely easing of some of these industry-wide challenges, and subsequent cost pressures, and a more detailed and considered understanding of the project and funding requirements. Inclusion of the recent high-grade results in our mineral resource base and mine plan will assist in offsetting the impact of rising capital and logistics costs related to the remote location of Jervois.

Despite the ongoing challenges the project is emerging as a significant copper and silver project located in a first-world jurisdiction, where all approvals are now in place. Jervois will offer customers a long-term supply of copper concentrate, with gold and silver credits, from a secure and stable operating environment in comparison to similar mines operating in more difficult geo-political jurisdictions.

Mr Finnis further commented,

”The delay in completing the Jervois Feasibility Study would, in more normal circumstances, represent a significant risk for shareholders. The recent discovery-record at Jervois increasingly indicates potential for a larger and potentially more robust asset coming to development in a demand environment driven by a global shift into vehicle electrification and renewable energy systems. Management and board are therefore hopeful in delivering a higher value asset for shareholders which we expect will attract significant interest from financiers.”

This announcement has been approved by the directors of KGL Resources Limited.

Mineral Resource Estimate for Reward Deposit, Jervois Project, NT

05/01/2022

1 SUMMARY

The Reward deposit is one of the deposits identified within KGL’s Jervois Project. The Jervois Project is located in the Northern Territory, 275 km ENE of Alice Springs. (22.65°S and 136.27°E). The Exploration Licence and four Mining Claims are 100% owned by KGL subsidiary Jinka Minerals Ltd.

Mining Associates Pty Ltd (“MA”) was commissioned by KGL Resources. (“KGL”, or the “Company”), a mineral exploration and development company currently listed on the Australian Stock Exchange (“ASX”), to prepare a Mineral Resource Estimate (“MRE”) and Technical Report on the Reward deposit.

Based on the reported study, delineated mineralization of the Reward Deposit is classified as Indicated and Inferred Mineral Resource according to the definitions outlined in JORC (2012). Confidence and classification regarding the grade estimates are based on several factors, including but not limited to sample and drill spacing relative to geological and geostatistical observations, the continuity of mineralization, mining history, bulk density determinations, accuracy of drill collar locations, quality of the assay data, and other estimation statistics.

The resource is reported above a depth of 200 m RL and a 0.5% copper cut off and below 200 m RL at a 1% copper cut off (200 m RL is approximately 150 m below the surface).

Weathering of the deposits has an impact on metallurgical recoveries. KGL is considering different processing and or differing recoveries based on the amount of sulphur and deleterious elements present. Table 2 shows the deposits reported by weathering profiles, including the High Sulphur resource (S/Cu > 4.5).

1.1 GEOLOGY AND GEOLOGY INTERPRETATION

Reward is interpreted as an original syn-depositional copper-rich polymetallic massive sulphide deposit that has undergone deformation, metamorphism and some degree of structural remobilisation. Recent modelling of mineralisation by KGL geologists strongly supports the interpretation of a low-grade, broadly stratabound zone, overprinted by higher grade ‘shoots’ that represent structural remobilisation into fold hinges and breccia style structures.

Interpretation of higher-grade zones is based primarily on geological logging supported by abrupt changes in copper and/or silver grades. High grade structural shoots are characterised by coarser grained sulphides and magnetite sulphide breccia. The lower grade stratabound halo was defined as greater than 0.5% sulphur. Intervals encompassing high grade shoots and stratabound mineralisation were modelled using Leapfrog software with an anisotropic component conforming to the plunge of measured F2 fold hinges.

Reward domains were created primarily based on structural shoots orientation (Figure 1), weathering and grade. Cross sections of the interpreted implicit models for Marshall shoot and Deeps South are shown in Figure 2 and Figure 3.

1.2 DRILLING TECHNIQUES

Resource definition drilling over the life of the project has been undertaken on 50 m spaced cross sections perpendicular to strike with holes spaced on average 50 m (50 x 50m grid). The higher grade shoots and shallower mineralisation (above 200m RL) has been infilled to approximately 25 x 50 m. Of the 598 holes (125 km of drilling) on the deposit, 70 holes (historical) have been rejected, deemed unreliable either in survey or have missing data. The total number of validated holes at Reward is 528 holes for 120 km of drilling.

KGL drilling since 2011 mostly utilised a combination of RC pre-collars (5.25” face sampling bit) to a predetermined depth above predicted mineralisation followed by diamond coring (wireline with dominantly HQ3 (63 mm) diameter with some NQ3 (45 mm) diameter). Pre-2011 hole diameter and drill type details are generally not recorded (NR) in the database. Table 3 summarises drilling statistics by drill hole type. RC_DD drill holes utilised RC pre-collars with diamond coring through zones of mineralisation, and DDW denotes diamond drilling wedges, or child holes drilled from a pre-existing hole path by directional drilling methods

Reverse circulation with diamond tail RC_DD 111 47501.29
Unknown drill method NR 50 6712.16
Total 528 120,364

1.3 SAMPLING AND SUB-SAMPLING TECHNIQUES

Sampling was continuous through mineralisation/alteration zones and extended up to 10 m for diamond core and up to 50 m for RC up and down-hole. The 2020-2021 sampling program has been all quarter sawn diamond core. Earlier sampling included quarter core and riffle split RC samples.

1.4 SAMPLE ANALYSIS

Since mid-2015 KGL has sent all samples to Intertek laboratories in Alice Springs for sample preparation, from where they were forwarded to Intertek in Townsville for analysis. Earlier 2011 to 2015 samples were sent to ALS Global in Townsville. Intertek and ALS analysis used a 4-acid digest with ICP-OES finish. Over-grade (> 2 % Cu) samples were re-analysed by 4-acid digest and ICP-OES finish on a larger initial sample and longer digest time. KGL QAQC protocols are designed to establish measurement systems and procedures to provide adequate confidence that quality is adhered to, and results are suitable for inclusion in Resource Estimation.

1.5 ESTIMATION METHODOLOGY

The Mineral Resource statement reported herein is a reasonable representation of the Reward deposit based on current sampling data. Grade estimation was undertaken using Geovia’s Surpac™ software package (v7.4.2). Ordinary Kriging (“OK”) was selected for grade estimation of copper, silver and gold (and the ancillary elements).

Copper is the primary economic element, silver, gold, lead, zinc, are estimated using the copper domains as hard boundaries and utilising dynamic search ellipses. Deleterious elements U W Bi and F are estimated within the sulphur domain (a soft boundary across the copper domains). Iron and Sulphur are estimated inside the sulphur domain using dynamic search ellipses. Iron and Sulphur are estimated into the country

rock to aid waste rock classification. Only Main shoot and Marshall have sufficient oxidised samples to enable the weathering profile to be used as an additional hard boundary.

The block model utilises parent blocks measuring 2.5 m x 10 m x 5 m with sub -blocking to 1.25 m x 5 m x 2.5 m to better define the volumes. Blocks above topography are excluded from the estimation. Estimation resolution was set at the parent block size. Due to the reasonably spaced drill patterns, search radii were found to be optimal near 70 m for the major axis of the search ellipse. Anisotropic ratios of 1.5 and 2.5 were applied to the semi-major and minor axis of the search ellipse. The minimum and maximum samples utilised were 8 and 20 for the first pass and reduced to 6 and 15 for the second pass. Third pass informing samples were further reduced to a minimum of 2 and maximum of 10. Search distances were factored by the estimation pass. Grade capping was applied to all elements except Fe and S. Experimental variograms were generated where possible. Domains and elements where experimental variograms could not be created, variogram models were borrowed from similar domains or elements (with weak to moderate corelations to the element under investigation).

The default density of the block model is 2.80 t/m[3] . All oxide material is assigned 2.6 t/m[3] . The mineralised transitional material is assigned 3.0 t/m[3] and the transitional waste is assigned a density of 2.8 t/m[3] . Density values were further improved with a 2-pass estimation strategy. Pass one used measured density readings (n = 13,577, average 3.01, Variance 0.1 and CV 0.105) to estimate the block density, the second pass used density values determined from a linear regression of iron assays. The mineral resource averages 3.08 t/m[3] .

Block model validation consisted of visual checks in plan and section, global comparisons between input and output means, alternative estimation techniques, swath plots and to previous estimates.

1.6 CUT-OFF GRADES

Cut off grades of 0.5% Cu above 200 m RL and 1% Cu below 200 m RL; 200 m RL is approximately 150 m below the surface and is considered to the depth limit for potential open pit mining. KGL are considering the optimal transition depth for the change over from open pit to underground in the FS currently under way.

Classified resources (combined indicated and inferred) as defined above are presented at increasing copper cut offs highlighting the deportment of associated elements (Table 4). Figure 4 shows the resource as grade tonnage curves by resource category.

Figure 4. Classified Resource - Grade Tonnage Curves

1.7 CRITERIA USED FOR CLASSIFICATION

Resource classification is based on data quality, drill density, number of informing samples, kriging efficiency, conditional bias slope, average distance to informing samples and geological continuity (deposit consistency). The confidence in the quality of the data and historic mining activities justified the classification of indicated and inferred resources. Data quality does not preclude Measured but geological confidence and grade continuity are not sufficiently defined to assign Measured Resources; this can change with further drilling.

Indicated resources are the portions of the deposit with a drill spacing of 50 m x 50 m and demonstrate a reasonable level of confidence in the geological continuity of the mineralisation, supported by some infill drilling. Inferred resources are the portions of the deposit covered by drill spacing greater than 50 m or those portions of the deposit with a smaller number of intercepts but demonstrating an acceptable level of geological confidence. Portions of the resource that do not meet these requirements remain unclassified resources and are not reported.

A mineral resource is not an ore reserve and does not have demonstrated economic viability.

1.8 MINING AND METALLURGICAL METHODS AND PARAMETERS AND OTHER MATERIAL MODIFYING FACTORS CONSIDERED TO DATA

The mineralisation above the 200 m RL (approximately 150 m below the surface) has been deemed to be potentially accessible by open cut mining methods The Reward Deposit is a large steeply dipping syndepositional copper deposit likely resulting in a high strip ratio. Mineralisation below the 200 m RL (approximately 150 m below the surface) is considered to have underground potential above a 1 % Cu cut off. No other mining assumptions have been used in the estimation of the Mineral Resource.

KGL have commissioned metallurgical testing of multiple composite samples from the Jervois project.

Mineral processing and metallurgical recoveries do not have a significant impact on the mineral resource estimate and have not been applied to the in-situ grades. Metallurgical recoveries are considered when

Sulphur has been estimated through-out the block model. Fe and S have been estimated within the S domain and outside the sulphur domain (waste rock). It is assumed that surface waste dumps will be used to store waste material and conventional storage facilities will be used for the process plant tailings. KGL is undertaking Kinetic test work to assess potential for acid mine drainage, preliminary results indicate most of the waste material recoverable by mining will have low potential to become acidic.

SECTION 1 SAMPLING TECHNIQUES AND DATA

Criteria JORC Code explanation
Commentary
Sampling
techniques
Nature and quality of sampling (e.g. cut
channels, random chips, or specific
specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
down hole gamma sondes, or handheld
XRF instruments, etc). These examples
should not be taken as limiting the broad
meaning of sampling.
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.

At Reward diamond drilling and reverse circulation (RC)
drilling were used to obtain samples for geological
logging and assaying. The core samples comprised a
mixture of sawn HQ quarter core, sawn NQ half core and
possibly BQ half core (historical drilling only). Sample
lengths are generally 1m, but at times length were
adjusted to take into account geological variations. RC
sample intervals are predominantly 1m intervals with
some 2 and 4m compositing (historical holes only).

RC samples are routinely scanned by KGL Resources with
a Niton XRF. Samples assaying greater than 0.1% Cu, Pb
or Zn are submitted forchemicalanalysis at a
commercial laboratory.

Mineralisation at all deposits(Jervois Project)is
characterized by disseminations, veinlets and large
masses of chalcopyrite, associated with magnetite-rich
alteration within a psammite. The mineralisation has
textures indicative of structural emplacement within
specific strata i.e. the mineral appearsremobilised
within astrataboundunit.

Documentation of the historical drilling (pre-2011) for
Reward is variable.
Drilling
techniques
Drill type (e.g. core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details
(e.g. core diameter, triple or standard
tube, depth of diamond tails, face-
sampling bit or other type, whether core
is oriented and if so, by what method,
etc).

The KGL and previous Jinka-Minerals RC drilling was
conducted using a reverse circulation rig with a 5.25-inch
face-sampling bit. Diamond drilling was either in NQ2 or
HQ3 drill diameters. Metallurgical diamond drilling (JMET
holes) were PQcore.

There is no documentation for the historic drilling
techniques, drill type is recorded as UNK.

Diamond drilling was generally cored from surface with
some of the deeper holes at Rockface and Reward
utilizing RC pre-collars.

the mineral zones having virtually 100% recovery.

No evidence has been found for any relationship
between sample recovery and copper grade and there
are no biases in the sampling with respect to copper
grade and recovery.
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.

All KGL RC and diamond core samples are geologically
logged. Logging in conjunction with multi-element assays
is appropriate for mineral resource estimation.

Core samples are orientated and logged for geotechnical
informationsuitable for mining studies.

All logging has been converted to quantitative and
qualitative codes in the KGL Access database.

All relevant intersectionsare logged.

Paper logs existed for the historical drilling. There is very
little historical core available for inspection.
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and
whether quarter, half or all core taken.
If non-core, whether riffled, tube
sampled, rotary split, etc and whether
sampled wet or dry.
For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.
Quality control procedures adopted for
all sub-sampling stages to maximise
representivity of samples.
Measures taken to ensure that the
sampling is representative of the in-situ
material collected, including for instance
results for field duplicate/second-half
sampling.
Whether sample sizes are appropriate to
the grain size of the material being
sampled.

The following describes the recent KGL sampling and
assaying process:

RC drill holes are sampled at 1m intervals and split using
a cone splitter attached to the cyclone to generate a split
of ~3kg;

RC sample splits (~3kg) are pulverized to 85% passing 75
microns.

Diamond core was quartered with a diamond saw and
generally sampled at 1m intervals with samples lengths
adjusted at geological contacts;

Diamond core samples are crushed to 70% passing 2mm
and then pulverized to 85% passing 75 microns.

Two quarter core field duplicates were taken for every
20m samples by Jinka Minerals and KGL Resources.

All sampling methods and sample sizes are deemed
appropriate for mineral resource estimation

Details for the historical sampling are not available.
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 (e.g. standards, blanks,
duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (i.e. lack of bias) and precision
have been established.

The KGL drilling has QAQC data that includes standards,
duplicates and laboratory checks. Inmineralisation
standards are added at a ratio of 1:10 and duplicates and
blanks 1:20.

Base metal samples are assayed using a four-acid digest
with an ICP AES finish. Gold samples are assayed by Aqua
Regia with an ICP MS finish. Samples over 1ppm Au are
re-assayed by Fire Assay with an AAS finish.

There are no details of the historic drill sample assaying
or any QAQC.

All assay methods were deemed appropriate at the time
of undertaking.

• Ordinary Kriging has been used as the interpolation
technique to estimate the Mineral Resource. This method
considered appropriate given the nature of mineralisation. All
elements were estimated using ordinary kriging.
• Estimation was undertaken in Surpac 2021 (v7.4.2).
• Drill hole interecpts were flagged manually within Surpac
with individual domain codes. The flagged drill hole
intercepts were imported into LeapFrog, and three
dimensional mineralisation wireframes created. Intervals
were checked for inconsistences, split samples, edge dilution
and mineralisation outside the interpretation. A separate
table was created to store drill hole intercepts greater than
0.2% S. these intercepts were domained as stratabound
mineralisation.
• The domain codes (for Cu and S) have then been used to
extract a raw assay file from MS Access for grade population
analysis (multi-element), as well as analysis of the most
appropriate composite length to be used for the estimation.
• Analysis of the raw samples within the Cu mineralisation
domains indicates that the majority of sample lengths are at
1 m. Samples were composited to one metre honouring
geological boundaries.
• Grade continuity analysis within Cu domains to define the
mineralisation has been undertaken.Where variograms could
not be generated for a particular element, variograms were
considered from adjacent domains.
• 3D experimental variogram modelling using a nugget (C0) and
two spherical models (C1, C2), occasionally one spherical
model was sufficient. Nuggets ragned from reasonable low to
high, between 0.20 and 0.73, and variogram ranges varied
between 60 and 150 m for Cu. The high nugget was for the
new domain main HW. Nuggets for additional elements
ranged from 0.2 to 0.7 and variogram ranges varied between
50 and 180 m..
• Anisotropic ellipses based on the resulting bearing, plunge,
dip, and defined ranges and anisotropic ratios were
graphically plotted in Surpac and displayed against the
extracted assay composites to ensure modelled parameters
were reasonably orientated. Estimation utilised dynamic
anisotropy based on local variations in domain orientation.
• The interpolations have been constrained within the
mineralisation wireframes and undertaken in three passes
with the mineralisation wireframes utilised as hard-
boundaries during the estimation.
• The first pass utilised a search distance of 70 m and a
minimum number of informing samples of 8, and a maximum
number of informing samples of 20. The second pass utilised
a minimum of 6 and maximum of 16 samples, the search
distance was doubled to 140 m. Both passes restricted the
maximum number of samplesper hole to 4. The thirdpass

dropped the minimum to 2 and maximum to 10 samples and
the restriction of samples per hole was lifted. Third pass
maximum distance was 210 m. 56% of estimated metal (> 0.5
% Cu) is estimated in pass 1.

characterisation is included in the block model.
• No specific assumptions have been made regarding selective
mining units. However the sub-blocks are of a suitable
selective mining unit size for either an open pit operation or
underground mining scenario.
• A 3D model with a parent block size of 2.5 m (X) by 10 m (Y)
by 5 m (Z) was used. The drill hole spacing in the deposit
ranges from 25 m by 25 m in the better drilled parts of the
deposit to the dominant 50 m by 50 m drill pattern. In order
for effective boundary definition, a sub-block size of 1.25 m
(X) by 5 m (Y) by 2.5 m (Z) has been used; the sub-blocks are
estimated at the parent block scale.
• There is a moderate to good corelation between Pb and Ag
and weak corelation between Bi and Ag. There is a moderate
(> 0.5) corelation between Cu, Pb, Zn, Ag Au and S. Fe is
associated with magnetite and shows a weak corelation (!0.3)
with S and Cu There is no corelation between F, U and W and
the other elements.
• The
geological

(grade

interpretations) were used to control grade estimation.
• High grade outliers (Cu, Pb, Zn, Ag, Au, Bi, F, U and W) within
the composite data were capped. No capping was applied to
Fe and S. Domains were individually assessed for outliers
using histograms, log probability plots and changes in average
metal content; grade caps were applied as appropriate.
Generally the domains defined a well distributed population
with low CV’s and only minimal grade-capping was required.
• The resource has been validated visually in section and level
plan along with a statistical comparison of the block model
grades against the composite grades to ensure that the block
model is a realistic representation of the input grades. No

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. Where this is the case, this
should be reported with an
explanation of the basis of the mining
assumptions made.
• The mineralisation above the 200 m RL (approximately 150 m
below the surface) has been deemed to be potentially
accessible by open cut mining methods The deposit is a large
steeply dipping syn-depositional copper deposit likely
resulting in a high strip ratio.
• Mineralisation below the 200 m RL (approximately 150 m
below the surface) is considered to have underground
potential above a 1 % Cu cut off.
• No other mining assumptions have been used in the
estimation of the Mineral Resource.
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. Where this is the case, this
should be reported with an
explanation of the basis of the
metallurgical assumptions made.
• No metallurgical factors have been applied to the in situ
grade estimates.
• Metallurgical Recoveries for copper and silver are
determined as functions of copper grade in oxide/transitional
and sulphide ore.
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.
Where these aspects have not been
considered this should be reported
with an explanation of the
environmental assumptions made.
• KGL is undertaking Kinetic test work to assess potential
for acid mine drainage, preliminary results indicate
most of the waste material recoverable by mining will
have low potential to become acidic.
• Sulphur has been estimated through-out the block model. Fe
and S have been esitmated within the S domain and outside
the sulphur domain (waste rock).
• It is assumed that surface waste dumps will be used to store
waste material and conventional storage facilities will be
used for the process plant tailings.
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
• Onsite measurements (13,846 density readings are matched
to an assay value) by water immersion method are only
conducted on competent transitional and fresh core. Limited
oxide samples have been taken.
• Dry bulk density has been varied according to the weathering
profile. Within Fresh material bulk density was estimated
(OK) directly from density readings. A minimum of 5 samples
and a maximum of 12 samples was used. In areas not filled
with estimated density values, a linear regression of iron
assays was employed; the calculated density data was then
used in a second pass.
• Reward - the average modelled densityof mineralised oxide

and differences between rock and
alteration zones within the deposit.

material is 2.60 t/m3, transitional material is 3.02 t/m3, the
high sulphide material averages 3.07 t/m3and mineralised
fresh material averages 3.09 t/m3
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.
• Blocks have then been classified as Indicated, Inferred or
Unclassified based on drill hole spacing, geological continuity
and estimation quality parameters.
• The above criteria were used to detemine areas of implied
and assumed geological and grade continuity.Only small
areas have confirmed geological and grade continuity, thus
no measured is yet defined. Classification was assessed on a
per domain basis and resoruce categories were stamped onto
the individual domains.
• Unclassified mineralisation has not been included in this
Mineral Resource. Unclassified material is either contained in
isolated block above cut off within the strata-bound domain
and in deep proportions of the deposit with sparse dill
intercepts.
• The classification reflects the competent person’s view of the
Reward deposit.
Audits or
reviews
The results of any audits or reviews of
Mineral Resource estimates.
• There has been a limited independent audit of the data
performed by MA, there has been no independent review of
the mineral resource.
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. For example, the
application of statistical or
geostatistical procedures to quantify
the relative accuracy of the resource
within stated confidence limits, or, if
such an approach is not deemed
appropriate, a qualitative discussion
of the factors that could affect the
relative accuracy and confidence of
the estimate.
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.
• With further drilling it is expected that there will be variances
to the tonnage, grade and contained metal within the
deposit. The competent person does not expect that these
variances will impact the economic extraction of the deposit.
• The mineral resource estimate appropriately reflects the
competent person’s view of the deposit.
• No geostatistical confidence limits have been estimated.
Consideration has been given to all relevant factors in the
classification of the mineral resource.
• The ordinary kriging result, due to the level of smoothing,
should only be regarded as a global estimate, and is suitable
as a life of mine planning tool.
• Should local estimates be required for detailed mine
scheduling, techniques such as Uniform conditioning or
conditional simulation could be considered. Ultimately grade
control drilling will be required.
• Limited Mining records exist (40 kt of oxide extracted from
Green Parrot – south of the resource). Some historic mining
has occurred on the Marshal – Reward structure, records are
insufficient to reconcile.
