INITIAL BALOO RESOURCE OF 123,000 OUNCES OF GOLD, OPEN DOWN PLUNGE

Highlights

  • Initial mineral resource estimate of 2.17Mt @ 1.8g/t for 123,000oz gold

  • Metallurgical, geotechnical and hydrological work underway

  • Remains open down plunge as a narrow high grade lode

  • Exploration drilling to start at Monsoon

S2 Resources Ltd (“S2” or the “Company”) advises that it has completed the first Mineral Resource estimate for the near surface portion of the Baloo gold deposit, located on its 100% owned Polar Bear project in the Eastern Goldfields of Western Australia. Exploration drilling of the Monsoon and Nanook gold prospects will also recommence shortly whilst various mining and processing testwork programs are undertaken at Baloo.

Baloo gold deposit

The initial Mineral Resource estimate for the Baloo gold deposit comprises 2,170,000 tonnes grading 1.8g/t gold for a contained 123,000 ounces of gold at a lower cutoff grade of 0.8g/t gold.

1,150,000 tonnes (or 53%) of this is classified as higher confidence Indicated category material, with the balance being lower confidence Inferred category material. 69,000 ounces (or 56%) of the total resource comprises the higher confidence Indicated category material, with the balance being lower confidence Inferred category material.

Table 1 and Figure 1 show the variation in tonnage, grade and contained gold at a variety of lower cutoff thresholds. At a reduced lower cutoff of 0.5g/t gold, tonnage increases by 50% to 3,260,000 tonnes, grade decreases by 21% to 1.4 g/t gold, and contained gold increases by 18% to 145,000 ounces of gold. At an increased lower cutoff of 1.0g/t gold, tonnage decreases by 26% to 1,620,000 tonnes, grade increases by 17% to 2.1 g/t gold, and contained gold decreases by 13% to 107,000 ounces of gold.

Figure 1. Baloo Gold Deposit – grade-tonnage curve for total Mineral Resources. All Mineral Resources are reported to JORC 2012. LCOG is lower cut-off grade.

A significant proportion of the Total Mineral Resource is located in a localized thick, near surface lens in the central part of the Baloo deposit (see Figures 2 to 4) and most of the Indicated Mineral Resource is also located in this area.

As shown in Figure 4, the 110 metre depth interval of the block model from 2 metres to 112 metres below surface (the 150m to 260m RL interval) contains significant ounces of gold per vertical metre, peaking at over 1,500 ounces per vertical metre. This is the part of the deposit which is most likely to be amenable to potential open pit mining.

Figure 4. Baloo Gold Deposit – chart showing ounces of Indicated, Inferred and total gold per vertical metre below the salt lake surface at an RL of 262 metres (flat red line) in the resource block model. This shows that the majority of the contained gold and the majority of the Indicated Resource in the block model is located in a 110 metre vertical depth interval from 150260 metre RL (ie, a depth below surface of 2-112 metres), with significant amounts of gold close to surface.

Near surface oxide and transitional mineralization comprises approximately 61% of the total Mineral Resource and 81% of the Indicated Resource, and this extends south and north from the central zone. The remainder of the resource comprises a deeper primary lode, which plunges to the south and remains open at depth (Figure 5).

==> picture [454 x 306] intentionally omitted <==

Figure 5. Baloo Gold Deposit – cross section through south plunging primary lode.

A metallurgical testwork program has commenced, with four composite samples representing four distinct oxide and transitional material domains being assessed for their comminution and CIL/CIP recovery characteristics. Testwork is also underway to establish the amenability of the oxide and transitional material to heap-leach extraction.

Geotechnical drilling of the potential open pit position is nearing completion. Geotechnical work on these and other previously drilled holes is underway with the aim of determining likely pit wall slope angles and design criteria.

Hydrological testwork, comprising pump testing of existing drill holes, is also underway to establish potential dewatering requirements.

Environmental studies are well advanced, with flora and fauna studies completed. Lake ecology studies and mine waste characterization studies are currently being undertaken.

Exploration

The Baloo mineralization remains open down plunge to the south, where several narrow but high grade drill intersections indicate the potential for a continuation of the mineralization beyond the limits of the current resource at a vertical depth of between 85 and 160 metres. Future drilling of this area will aim to define the down plunge extent and continuity of the primary gold lode(s).

Baloo is located in the middle of a 30 kilometre long trend. The next drilling to the south of Baloo along this trend is approximately 4 kilometres to the south at the Monsoon prospect, where reconnaissance hole SPBA2833 (the last hole drilled on the last line drilled) intersected 32 metres @ 2.47 g/t gold (see Figure 6).

Once the geotechnical drilling is complete, the lake rig will move to the Monsoon prospect to follow up this intersection, and then on to the Nanook prospect with the aim of defining the extent and magnitude of any additional oxide mineralization prior to deeper drilling at Baloo.

The following Tables are provided to ensure compliance with the JORC code (2012) edition requirements for the reporting of exploration results.

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.
In zones of weakly weathered or fresh rock the HQ or NQ2 core
is cut using a diamond core saw with half core sampled for assay.
The ore is cut along the orientation line, with the same side
sampled to ensure sample is representative.
In zones of highly weathered core where the sample is either
highly broken or highly friable and a representative split cannot
be achieved then whole core sample of either the PQ3 or HQ3
core is taken.
For RC sampling, a 1 metre split is taken directly from a cone
splitter mounted beneath the rigs cyclone. The cyclone and
splitter are cleaned regularly to minimise any contamination. A
second reference split is also taken from each metre and stored
on site.
Aircore holes are sampled using an aluminium scoop to
produce a four metre composite sample similar to the RC
sampling methodology.
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or systems
used
Sampling and QAQC procedures is carried out using S2
protocols as per industry best practice.
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
Reconnaissance aircore samples are composited at 4 m to
produce a bulk 3 kg sample. Samples were dried, pulverised
(total prep), and split to produce a 25 g sub sample which is
analysed using aqua-regia digestion with ICP-MS finish with a 1
ppb detection limit.
A 1m end of hole sample was collected for all aircore holes.
Sample preparation was the same as above and were analysed
using a four acid digest with an ICP/OES and fire assay. The
following elements are included in the assay suite: Ag, Al, As,
Au, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Fe, K, La, Mg, Mn, Mo, Na,
Ni, P, Pb, Sb, Sc, Sr, Te, Ti, Tl, V, W, Zn.
RC drilling is sampled a 1m “cone” split sample, to produce a
bulk 3 kg sample. Sample preparation was the same as for the
aircore drilling. A nominal 50gram sub-sample was collected
and analysed by Samples were to produce a sub sample for
analysed by fire assay with an AA finish.
Diamond core (HQ and NQ2) is half core sampled to geological
boundaries of no more than 1m and no less than 30cm.
Samples were crushed, dried and pulverised (total prep).
Analysis is same as for RC.
Oxide PQ3 core is whole core sampled and then dried, crushed
to -2mm and then rotary split to a 3kg sample for pulverisation
and 50g fire assay.
Criteria JORC Code explanation Commentary
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).
Diamond drilling is completed using either NQ2, HQ, or PQ3
(through the oxide zone) sized coring equipment. All core is
orientated (where possible) using a Reflex ACT II RD orientation
tool.
RC drilling is carried out using a face sampling hammer with a
nominal diameter of 140mm.
Aircore drilling is carried out using a 3 ½ inch blade bit. Where
necessary a 3 ½ inch face sampling hammer is employed to
penetrate through hard zones.
Drill sample
recovery
Method of recording and assessing core and chip
sample recoveries and results assessed
Diamond core recoveries is logged and captured in the database.
The core length recovered is measured for each run and
recorded which is used to calculate the core recovery as a
percentage core recovered.
RC and aircore sample recoveries are visually estimated
qualitatively on a metre basis and are recorded in the database.
Measures taken to maximise sample recovery and
ensure representative nature of the samples
Measures taken to maximise the core recoveries includes using
appropriate core diameter and, where necessary, restricting drill
penetration and/or reducing core runs.
Triple tube diamond core through the weathered zone is too
broken to allow core cutting and therefore the core is sampled
whole to ensure no bias is introduced.
Various drilling additives (including muds and foams) have been
used to condition RC and aircore drill holes to maximise
recoveries and sample quality. Drill cyclone and sample buckets
are cleaned between rod-changes and after each hole to
minimise down hole and/or cross-hole contamination.
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.
Core drilling has resulted in narrow zones of poor to no core
recoveries through the oxide zone in areas of very soft clays and
fault gouge within the weathered zones. These are recorded as
poor or zero recovery and not assigned grade.
Aircore drilling samples are occasionally wet which may have
resulted in sample bias due to preferential loss/gain of
fine/coarse material.
No sample recovery issues have impacted on potential sample
bias within coring of fresh rock or within RC drilling.
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.
Geological logging is completed for all holes to a level of detail
that would, where sufficient drill density is completed, support
an appropriate Mineral Resource and mining study.
Lithology, alteration, veining, structural and geotechnical
(diamond core) characteristics is recorded directly to a digital
format and imported into S2 Resources central database.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
Logging is both qualitative and quantitative in nature depending
on the field being captured.
All core is photographed
The total length and percentage of the relevant
intersections logged
All drillholes were logged in full.
Criteria JORC Code explanation Commentary
Sub-sampling
techniques and
sample preparation
If core, whether cut or sawn and whether quarter,
half or all core taken.
In zones of highly weathered core where the sample is either
highly broken or highly friable the PQ3 or HQ3 core is sampled
whole core. Oxide whole core is submitted to the lab in samples
not exceeding 6kg and then coarse crushed to <2mm. Samples
are then rotary split to provide a 3kg sub sample for
pulverisation.
In zones of weakly weathered or fresh rock the HQ or NQ2 core
is cut using a diamond core saw with half core sampled for assay.
If non-core, whether riffled, tube sampled, rotary
split, etc and whether sampled wet or dry.
RC and aircore samples consist of a 4 metre composite RC spoils
are sampled by scoop. All RC holes are sampled 1 metre samples
are collected via an on-board cone splitter. Samples were
collected both wet and dry.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
The sample preparation follows industry best practice in sample
preparation All samples are pulverised utilising Essa LM1, LM2
or LM5 grinding mills determined by the size of the sample.
Samples are dried, crushed as required and pulverized to
produce a homogenous representative sub-sample for analysis.
A grind quality target of 85% passing 75μm has been established
and is relative to sample size, type and hardness.
Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
Quality control procedures include submission of Certified
Reference Materials (CRM’s), blanks and duplicate samples with
each batch of samples. Selected samples are also re-analysed to
confirm anomalous results.
Grind size checks are routinely completed to ensure samples
meet the industry standard of 85% passing through a 75µm
mesh.
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.
Field duplicates are taken at regular intervals. Samples are
selected to weigh less than 3kg to ensure total preparation at
the pulverisation stage.
Whether sample sizes are appropriate to the grain
size of the material being sampled.
Sample sizes are considered appropriate for nickel sulphide and
gold mineralisation.
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.
RC and diamond core samples are analysed for Au only using a
40g or 50g Lead Collection fire Assay with either an ICP/MS or
AAS finish.
4m composite samples from AC drilling are analysed for Au only
using a 25g aqua-regia digestion with an ICP/MS finish. The
method gives a near total digestion of the regolith intercepted
in aircore drilling and is suitable for the reconnaissance style
sampling undertaken. Infill 1m samples and samples greater
than 1 g/t are re-assayed using 50 g fire-assay with AAS finish
which gives total digestion and is more appropriate for samples
with high levels of gold.
All aircore holes (both gold and nickel exploration) have a 1m
end-of-hole sample is collected for all AC holes. An extensive
multi-element suite (including Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce,
Co, Cr, Cu, Fe, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Sc, Sr, Te, Ti,
Tl, V, W, Zn) is analysed using a four acid digest with an ICP/OES
and ICP/MS finish. Au, Pt And Pd is analysed for using 25g or 50g
Lead Collection fire assay with an ICP/MS finish.
Criteria JORC Code explanation Commentary
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.
No geophysical tools were used to determine any element
concentrations used in this resource estimate.
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.
Sample preparation checks for fineness were carried out by the
laboratory as part of their internal procedures to ensure the
grind size of 85% passing 75 micron was being attained.
Laboratory QAQC involves the use of internal lab standards using
certified reference material, blanks, splits and replicates as part
of the in house procedures.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
The Exploration Manager of S2 has visually verified significant
intersections.
The use of twinned holes. No twin holes have been drilled on the project to date.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Primary data was collected using a set of standard Excel
templates using lookup codes. The information was sent to an
external database consultant for validation and compilation into
a Perth based SQL database.
Discuss any adjustment to assay data. No adjustments or calibrations were made to any assay data
reported.
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.
At Baloo all aircore and diamond drilling is picked up by an
external surveyor using an RTK GPS system with an expected
accuracy is +/– 0.05m for easting, northing and elevation.
RC drill sites were laid out by an external surveyor using an RTK
GPS system or tape and compass off surveyed collars. All holes
will be picked up by the external surveyor prior to any resource
calculations.
Specification of the grid system used. The grid system used at Polar Bear is GDA94 (MGA), zone 51.
Quality and adequacy of topographic control. A topographic surface has been created from aerial geophysical
data, This has been calibrated with DGPS survey data. All
reconnaissance drill holes have been corrected to this surface
where DGPS pickup is not available.
All resource drilling will be picked up by DGPS to within a +/-
50mm accuracy.
Data spacing and
distribution
Data spacing for reporting of Exploration Results. Data spacing is currently defined by the geological criteria
regarded
appropriate
to
determine
the
extents
of
mineralisation. Reconnaissance AC drilling is on a nominal
spacing of between 240m x 40m and 400m x 40m drill pattern,
with infill of resource areas closing down to a nominal 40m x
20m drill pattern for AC, RC and diamond.
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.
Drilling is currently preliminary in nature had the mineralised
domains have not yet demonstrated sufficient continuity in both
geological and grade continuity to support the definition of
Mineral Resource and Reserves, and the classifications applied
under the 2012 JORC Code.
Whether sample compositing has been applied. No compositing has been applied to the exploration results.
Criteria JORC Code explanation Commentary
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.
The drilling is not necessarily drilled perpendicular to the
orientation of the intersected mineralisation. All reported
intervals are downhole intervals and not calculated true width.
This will be established with further drilling.
At Baloo the main mineralised structure appears to be dipping
moderately to the east and hence 270 azimuth diamond drilling
give approximately true width intersections. Supergene
dispersion appears relatively flat lying and hence the vertical AC
holes also approximate to true thickness.
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.
No orientation based sampling bias has been identified in the
data at this point.
Sample security The measures taken to ensure sample security. Chain of custody is managed by S2 Resources. Samples are
stored on site and either delivered by S2 personnel to Perth and
then to the assay laboratory, or collected from site by Centurion
Transport and delivered direct to the assay laboratory. Whilst in
storage, they are kept on a locked yard. Tracking sheets have
been set up to track the progress of batches of samples.
Audits or reviews The results of any audits or reviews of sampling
techniques and data.
No audits or reviews have been conducted at this stage.

elevation above sea level in metres) of
the drill hole collar

dip and azimuth of the hole

Refer to Annexure1 in body of text.
Data aggregation
methods
In reporting Exploration Results, weighting
averaging techniques, maximum and/or minimum
grade truncations (e.g. cutting of high grades) and
cut-off grades are usually Material and should be
stated.
All reported assays have been length weighted. A top-cut of 30
g/t Au has been applied to individual assays when reported
intervals are greater than one metre.
A nominal 0.5 g/t Au lower cut-off is used for RC and diamond
intersections (unless otherwise stated). A nominal 0.1 g/t Au
lower cut-off is used to report AC intersections.
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.
High grade gold intervals internal to broader zones of
mineralisation are reported as included intervals.
The assumptions used for any reporting of metal
equivalent values should be clearly stated.
No metal equivalent values are used for reporting exploration
results.
Relationship
between
mineralisation
widths and intercept
lengths
These relationships are particularly important in
the reporting of Exploration Results.
If the geometry of the mineralisation with respect
to the drill hole angle is known, its nature should
be reported.
If it is not known and only the down hole lengths
are reported, there should be a clear statement to
this effect (e.g. ‘down hole length, true width not
known’).
The trend of mineralisation atBalooappears broadly north
south and dipping moderately to the east with the intervals
reported near true width.
All other prospects, the geometry of the primary mineralisation
is not known at present due to the lack of deeper drilling and the
early stage of exploration.
Refer to Annexure 1 and Figures in body of text.
Diagram Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for
any significant discovery being reported These
should include, but not be limited to a plan view of
drill hole collar locations and appropriate sectional
views.
Refer to Figures in body of text.
Balanced reporting Where comprehensive reporting of all Exploration
Results is not practicable, representative reporting
of both low and high grades and/or widths should
be practiced to avoid misleading reporting of
Exploration Results.
The accompanying document is conserved to represent a
balanced report with grades and/or widths reported in a
consistent manner.

Other substantive
exploration data
Other exploration data, if meaningful and
material, should be reported including (but not
limited to): geological observations; geophysical
survey results; geochemical survey results; bulk
samples – size and method of treatment;
metallurgical test results; bulk density,
groundwater, geotechnical and rock
characteristics; potential deleterious or
contaminating substances.
Two vertical PQ3 holes have been drilled in the core of the
weathered mineralization to allow bulk density determination
and provide samples for metallurgical testwork.
Three geotechnical holes have been drilled in the western
portion of the deposit to investigate geotechnical ground
conditions in the footwall of a potential open pit.
Groundwater monitoring has been initiated with insertion of
PVC into selected holes to allow a first pass pump test.

mineralized zone will follow. More reconnaissance drilling will
also be performed along strike to the south at Monsoon

SECTION 3 ESTIMATION AND REPORTING OF MINERAL RESOURCES

Criteria JORC Code explanation Commentary
Database integrity Measures taken to ensure that data has not been
corrupted by, for example, transcription or keying
errors, between its initial collection and its use for
Mineral Resource estimation purposes.
Data templates with lookup tables and fixed formatting are used
for logging, spatial and sampling data. Data transfer is electronic
via e-mail. Sample numbers are unique and pre-numbered bags
are used. These methods all minimise the potential of these
types of errors.
Data validation procedures used. Data validation checks are run by the database management
consultant.
Site visits Comment on any site visits undertaken by the
Competent Person and the outcome of those visits.
Multiple site visits to the Baloo deposit by Andy Thompson
during diamond and RC drilling to verify sampling integrity and
recovery. Site visit by Andy Thompson and Brian Wolfe acting
as Competent Persons, inspected the deposit area, the core
logging and sampling facility. During this time, notes and
photos were taken along with discussions were held with site
personnel regarding the available RC samples and diamond
core. No issues were encountered.
If no site visits have been undertaken indicate why
this is the case.

Geological
interpretation
Confidence in (or conversely, the uncertainty of)
the geological interpretation of the mineral
deposit.
The confidence in the geological interpretation is considered
good. The deposit is a mesothermal lode gold style typical of
the Kalgoorlie Archaean terrane.
Nature of the data used and of any assumptions
made.
Petrography has been used to assist identification of the rock
type subdivisions applied in the interpretation process.
The effect, if any, of alternative interpretations on
Mineral Resource estimation.
The deposit is well constrained and predictable with clear
boundaries which define the mineralised domains. Infill drilling
has supported and refined the model and the current
interpretation is thus considered to be robust.
The use of geology in guiding and controlling
Mineral Resource estimation.
Geological controls and relationships were used to define sub-
domains. Key features are quartz veining in a deformed
lithological contact zone.
The factors affecting continuity both of grade and
geology.
Gold grades are strongly related to deformed quartz veining
within a shearzone formed on the contact of basalt, black shale
and volcanoclastics
Criteria JORC Code explanation Commentary
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 Mineral Resource area has dimensions of 700 m (north) by
350 m (east) and 250 m (elevation).
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 Mineral Resource estimate was generated via MIK and
indirect lognormal change of support to emulate mining
selectivity. Additionally, areas of mineralization of less certain
grade continuity unsuited to grade estimation via MIK have been
estimated
by
ordinary
Kriging.
Mineralised
domain
interpretation was completed as described above and
approximates a 0.3g/t Au lower cutoff. The interpretation was
coded to the drill hole database and 3m length composites were
generated within the mineralisation boundary. A series of
indicator transforms were applied to the composites as
determined
by
statistical
evaluation
and
indicator
semivariograms were modelled for each cut-off. The
semivariograms were input in preparation for kriging of the
indicator transformed data. Hard boundaries were applied to
the kriging. A search neighbourhood was applied parallel to the
strike and dip with radii of 50m, 50m and 15m in the strike, down
dip and across strike directions respectively. Sample counts for
the estimates were set at a minimum of 24 and a maximum of
36. In the case of the domains estimated by OK, an expanded
search ellipsoid of 100m x 100m x 30m and a sample count of 6
were applied. Any blocks not estimated in the first estimation
pass were estimated in a second pass with expanded search
neighbourhoods and relaxed sample limits to allow the domains
to be fully estimated. Extrapolation of the drillhole composite
data is generally limited to approximately 50m down dip.
Change of support via the indirect lognormal method has been
applied to the indicator kriging results to emulate selectivity at
the mining stage.
The availability of check estimates, previous
estimates and/or mine production records and
whether the Mineral Resource estimate takes
appropriate account of such data.
This is a maiden Mineral Resource for the Baloo deposit and no
previous mining activity has taken place in this area.
The assumptions made regarding recovery of by-
products.
No by-products are assumed.
Estimation of deleterious elements or other non-
grade variables of economic significance (e.g.
sulphur for acid mine drainage characterisation).
No other elements have been assayed.
In the case of block model interpolation, the block
size in relation to the average sample spacing and
the search employed.
The parent block size is 20mN x20mE x 10mRL, with sub-celling
to 5mE x 5mN x 2.5mRL for domain volume resolution. The
parent block size was chosen based on estimation
methodology and relates to a drill section spacing of 40m to
20m and an on-section drill spacing of approximately 20m. The
search ellipse was oriented with axes rotated parallel to the
mineralised bodies as previously described.
Search ellipse dimensions were chosen to encompass several
drillholes up and down dip and several lines of drilling along
strike
Any assumptions behind modelling of selective
mining units.
Selective mining unit assumptions were based on dimension
and spacing of drill sampling, geometry of the mineralisation,
likely method of mining (open pit) and equipment used, likely
grade control and drill and blast dimensions. In consideration
of the parent cell dimension described above, an SMU of
5mE x 5mN x 2.5mRL has therefore been applied.
Any assumptions about correlation between
variables.
Not applicable

Description of how the geological interpretation
was used to control the resource estimates.
The geological model domained the oxide, transitional and
primary mineralisation to geological and structural zones.
These domains were used as hard boundaries to select sample
populations for variography and estimation.
Discussion of basis for using or not using grade
cutting or capping.
Top cutting of grades is not relevant in the context of MIK
methodology and has only been considered in the case of the
grade variogram used to calculate the change of support
variance reduction coefficient. In the case of the OK estimates,
grade has been capped to either 15g/t Au or 20g/t Au
depending on the domain.
The process of validation, the checking process
used, the comparison of model data to drillhole
data, and use of reconciliation data if available.
No mining has taken place; therefore no reconciliation data is
available.
Moisture Whether the tonnages are estimated on a dry
basis or with natural moisture, and the method of
determination of the moisture content.
The tonnages are estimated on a dry basis.
Cut-off parameters The basis of the adopted cut-off grade(s) or quality
parameters applied
A 0.8g/t Au cut-off grade was used to report the Mineral
Resources. This cut-off grade is estimated to be the minimum
grade required for economic extraction.
A range of additional cut-off grades have been reported up to
1.5g/t Au
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.
Mining of the Baloo deposit will by open cut mining methods.
The geometry of the deposit will make it amenable to mining
methods currently employed in many gold open pits in the
Kalgoorlie district. It is assumed that any pit will be mined on
2.5m benches with grade control drilling density sufficient to
allow selectivity assumed in the estimation.
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.
Preliminary metallurgical testwork in the primary
mineralisation indicates that the mineralisation is amenable to
standard cyanide leach extraction.
Environmental
factors or
assumptions
Assumptions made regarding possible waste and
process residue disposal options. It is always
necessary as part of the process of determining
reasonable prospects for eventual economic
extraction to consider the potential environmental
impacts of the mining and processing operation.
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
No assumptions have been made and these will form part of
the scoping study commencing in April 2016.
Criteria JORC Code explanation Commentary
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.
Dry Bulk Densities were determined by the Archimedes
principle (immersion) where possible and also by the direct
measurement method (caliper) in the oxide clay. Samples were
measured directly from the rig (wet bulk density) and then the
samples were dried at Minanalytical to determine moisture
content so that Dry Bulk Density (DBD) could be calculated.
In total 86 oxide samples, 77 transition zone samples and 282
primary zone samples were collected from mineralized zones.
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,
Bulk density has been estimated from density measurements
carried out on PQ3 core samples using the Archimedes method
(immersion) of dry weight versus weight in water using
clingwrap to waterproof the core. The caliper method was also
used in saprolitic oxide clay and showed good correlation with
the immersion method.
Discuss assumptions for bulk density estimates
used in the evaluation process of the different
materials.
The bulk density values were assigned as an average value to
the three weathering domains, oxide, transition and fresh.
Classification The basis for the classification of the Mineral
Resources into varying confidence categories
The Mineral Resource classification is based on good
confidence in the geological and grade continuity, along with
20 m by 20 m or 20 x 40m spaced drillhole density.
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).
The input data is comprehensive in its coverage of the
mineralisation and does not favour or misrepresent in-situ
mineralisation.
The validation of the block model shows good correlation of
the input data to the estimated grades.
Whether the result appropriately reflects the
Competent Person’s view of the deposit.
The Mineral Resource estimate appropriately reflects the view
of the Competent Persons.
Audits or reviews The results of any audits or reviews of Mineral
Resource estimates.
This is the maiden Baloo deposit Mineral Resource estimate.
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 relative accuracy of the Mineral Resource estimate is
reflected in the reporting of the Mineral Resource as per the
guidelines of the 2012 JORC Code.
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
The statement relates to global estimates of tonnes and grade.
These statements of relative accuracy and
confidence of the estimate should be compared
with production data, where available
No production data is available.
