4 Future Work

4.1 In-mine Exploration

Drilling will continue to test the extents of K2 down from the Pegasus 5817 & 5920 Drill Drives. The Raleigh corridor will be targeted later into the quarter.

4.2 Resource Development

Follow up drilling is planned in the Sir Walter and Raleigh South prospect. The planned drilling will target the upper portions and southern extensions of the Raleigh Main Vein.

The current Drake resource targeting program is due to be completed in the next quarter.

4.3 Regional Exploration

An RC hole is planned to be drilled in the coming quarter at Beverly Hills to supplement the initial diamond hole and confirm the tenure of grade within the stockwork vein mineralisation target. Resampling of historic drilling at Beverly Hills and reinterpretation of the prospect is planned for the December quarter.

A regional review of historic core within the Black Flag Group volcaniclastics will continue through the December quarter. The implementation of a new logging system will lead to new targets within the Black Flag Group for current and future drilling programs.

JORC Code, 2012 Edition – Table 1

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria JORC Code Explanation Commentary
Sampling techniques
Nature and quality of sampling (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 1m
samples from which 3kg was pulverised to produce a 30g 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.
Sampling was completed using Diamond (DD).


Diamond core was transferred to core trays for logging and sampling. Half core or full core
samples were nominated by the geologist from HQ or NQ diamond core, with a minimum sample
width of 20cm and a maximum width of 120cm.

RC drilling was used for precollars only and was not sampled.

Samples were transported to various analysis laboratories in Kalgoorlie for preparation by drying,
crushing to <3mm, and pulverizing the entire sample to <75μm.

300g Pulp splits were analysed in laboratories in both Kalgoorlie and Perth for 40g Fire assay
charge and AAS analysis for gold.
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.).

Rock rolling and RC pre-collars were used from surface to either set depths of 102m (Sir Walter) or
until top of fresh (Drake and Raleigh South) before commencing diamond tails through target
with HQ3 (core diameter = 61.1mm) for Raleigh South and Sir Walter, and HQ2 (core diameter =
63.5mm) for Drake.

For underground drilling and where HQ drilling was impractical from surface, NQ2 (50.6mm)
diameter core was used.

Core was orientated using and electronic 'back-end tool' core orientation system.

RC Drilling was completed using a 5.25" drill bit.
Drill sample recovery
Method of recording and assessing core and chip sample recoveries
and results assessed.

Measures taken to maximise sample recovery and ensure
representative nature of the samples.

Whether a relationship exists between sample recovery and grade
and whether sample bias may have occurred due to preferential
loss/gain of fine/coarse material.
For diamond drilling the contractors adjust their rate of drilling and method if recovery issues arise.

All recovery is recorded by the drillers on core blocks. This is checked and compared to the
measurements of the core by the geological team. Any issues are communicated back to the
drilling contractor.

Recovery was excellent for diamond core and no relationship between grade and recovery was
observed.
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 diamond core is logged for regolith, lithology, veining, alteration, mineralisation and structure.
Structural measurements of specific features are taken through oriented zones. All logging is
quantitative where possible and qualitative elsewhere. A photograph is taken of every core tray.

All AC samples are logged in one metre intervals for regolith and veining, and for lithology,
mineralisation, and alteration where visible. A photograph is taken of each hole, displaying every
sample for each hole.
All RC sample chips are logged in one metre intervals for regolith and veining, and for lithology,

mineralisation, and alteration where visible. A photograph is taken of the collected chip trays of

Criteria JORC Code Explanation Commentary
each hole.
All data for diamond, RC and AC was recorded digitally.
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.

K2 (Drake) mineralised diamond core was half-core sampled after cutting longitudinally with an
automated core saw.

Raleigh Main Vein (Raleigh South and Sir Walter) diamond core was whole-core sampled.

All diamond core that was half-core sampled was cut longitudinally with an automated core saw.

Sample preparation was conducted at various laboratories in Kalgoorlie, commencing with
sorting, checking and drying at less than 110°C to prevent sulphide breakdown. Samples are jaw
crushed to a nominal -6mm particle size. The entire crushed sample is then pulverized to 90%
passing 75μm, using a Labtechnics LM5 bowl pulveriser. 300g Pulp subsamples are then taken with
an aluminium scoop and stored in labelled pulp packets.

Grind checks are performed at both the crushing stage (3mm) and pulverising stage (75μm),
requiring 90% of material to pass through the relevant size to ensure consistent sample
preparation.

Screen Fire Assay (SFA) analysis was completed on selected samples where coarse visible gold
was observed in the core.
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.

A 40-50g fire assay charge is used with a lead flux, dissolved in the furnace. The prill is totally
digested in HCl and HNO3 acids before Atomic Absorption Spectroscopy (AAS) determination for
gold analysis. This method ensures total gold is reported appropriately.

Screen Fire Assay (SFA) analysis using a 75μm screen separates a sample into oversize and
undersize which are then both fire assayed, with a total gold content calculated from these
results. This method is equivalent to assaying an entire sample to extinction and ensures total gold
is reported appropriately.

No geophysical tools were used to determine any element concentrations.

Certified Reference Materials (CRMs) are inserted into the sample sequence randomly at a rate
of 1 per 20 composite samples to ensure correct calibration. Any values outside of 3 standard
deviations are scrutinised and re-assayed with a new CRM if the failure is deemed genuine.

Blanks are inserted into the sample sequence at a rate of 1 per 20 composite samples. Failures
above 0.2g/t are scrutinised, and re-assayed if required. New pulps are prepared if failures
remain.

All sample QAQC results are assessed by geologists to ensure the appropriate level of accuracy
and precision when the results have been returned from the laboratory.
Verification of
sampling and
assaying

The verification of significant intersections by either independent or
alternative company personnel.

The use of twinned holes.
Documentation of primary data, data entry procedures, data

verification, data storage (physical and electronic) protocols.

Discuss any adjustment to assay data.

All significant intersections are verified by the project geologist and senior geologist during the
drill hole validation process.

No holes were twinned as part of the programmes in this report.

Geological logging was captured using Acquire database software. Both a hardcopy and
electronic copy of these are stored. Assay files are received in csv format and loaded directly
into the database by the supervising geologist who then checks that the results have been
inserted correctly. Hardcopy and electronic copies of these are also kept. No adjustments are
made to this assay data.
Location of data
points

Accuracy and quality of surveys used to locate drill holes (collar and
down-hole surveys), trenches, mine workings and other locations used
in Mineral Resource estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.

A planned hole is pegged using a GPS by the field assistants for surface holes and by a site
surveyor for underground holes.

During RC drilling, whole-hole gyroscopic surveys are every 50m to ensure the hole remains close
to design.

During surface diamond hole drilling continuous gyroscopic surveys are conducted at 30m, 50m,
and then every 100m down hole to design depth to ensure the hole remains close to design.
The final hole collar for each diamond hole is picked up after drillhole completion by DGPS in the

MGA 94_51 grid for surface holes and picked up in the mine grid by mine surveyors for
underground holes.

Criteria JORC Code Explanation Commentary

Good quality topographic control has been achieved through regional topographic maps
(±2.5m) based on photogrammetry data.
Data spacing and
distribution

Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the

degree of geological and grade continuity appropriate for the
Mineral Resource and Ore Reserve estimation procedure(s) and
classifications applied.

Whether sample compositing has been applied.

Early stage diamond and RC drilling is variably spaced to effectively test the desired target.
Spacings of the regional drilling programmes range from 80m apart through to several hundred
metres apart through to isolated single drillholes in some cases. These variable spacings are
considered appropriate for early-stage testing of exploration targets.

In-mine diamond drillholes spacings are also variable from 80m apart through to isolated single
drillholes. Closer spaced drilling is considered operational drilling, beyond the scope of this report.

No compositing has been applied to these exploration results, although composite intersections
are reported.
Orientation of data in
relation to geological
structure
Whether the orientation of sampling achieves unbiased sampling of

possible structures and the extent to which this is known, considering
the deposit type.

If the relationship between the drilling orientation and the orientation
of key mineralised structures is considered to have introduced a
sampling bias, this should be assessed and reported if material.

All drilling both underground and surface is oriented as close as practical to perpendicular to the
target structures. The orientation of all in-mine target structures is well known and drill holes are
only designed where meaningful intercept angles can be achieved.

No sampling bias is considered to have been introduced by the drilling orientation.
Sample security The measures taken to ensure sample security.

Prior to laboratory submission samples are stored by Northern Star in a secure yard. Once
submitted to the laboratories they are stored in a secure fenced compound and tracked through
their chain of custody via audit trails.
Audits or reviews
The results of any audits or reviews of sampling techniques and data.

No audits or reviews have recently been conducted on sampling techniques, however lab audits
are conducted on a regular basis.

the tenement is in good standing.
Exploration done by
other parties
Acknowledgment and appraisal of exploration by other parties.

Underground drilling on the Raleigh and Hornet-Rubicon-Pegasus mines extends the mineralised
trends from older drilling including that of previous operators of those mines including Barrick Gold,
Placer Dome Asia-Pacific, Aurion Gold and other predecessors.

Surface drilling on the Raleigh South and Sir Walter prospects similarly extends from the mineralised
trend of Raleigh from those same predecessors.

Exploration work by Barrick Gold, Placer Dome Asia-Pacific, Aurion Gold and Goldfields Limited
defined the Beverly Hills and Ambition prospects and placed a small number of RC and diamond
drillholes into Beverly hills and RC holes into Ambition.
Geology
Deposit type, geological setting and style of mineralisation.

The Kundana camp is situated within the Norseman-Wiluna Greenstone Belt, in an area
dominated by the Zuleika Shear Zone, which separates the Coolgardie domain from the Ora
Banda domain. The Zuleika Shear Zone in the Kundana area comprises multiple anastomosing
shears the most important of which are the K2, the K2A and Strzelecki Shears.

Raleigh mineralisation is hosted on the Strzelecki Structure. Strzelecki mineralisation consists of
very narrow, very high-grade mineralisation on a laminated vein hosted in the camp-scale
Strzelecki Shear which abuts a differentiated mafic intrusive, the Powder Sill Gabbro against
intermediate volcanoclastic rocks (Black Flag Group). A thin 'skin' of volcanogenic lithic
siltstone-sandstone lies between the gabbro and the Strzelecki shear. Being bound by an
intrusive contact on one side and a sheared contact on the other, the thickness of the
sedimentary package is highly variable from absent to about forty metres true width.

The Hornet-Rubicon-Pegasus mineralisation consists primarily of high-grade laminated vein hosted
gold on the K2 plane of the Zuleika shear with additional mineralisation on associated lower order
structures. The Falcon target is a related mineralised zone in the hanging wall to Pegasus and
between the two main Zuleika structures, the K2 and Strzelecki structures.

The Ambition mineralisation is hosted within a laminated quartz vein on the K2 plane of the Zuleika
shear which is adjacent to the contact between the Powder Sill Gabbro and the volcaniclastic
rocks of the Black Flag Group.

Two kinds of mineralisation styles are present at Beverly Hills. A narrow high-grade shear-vein on
the Black Flag Group volcaniclastic sediment and Powder Sill Gabbro contact (the northern
continuation of the Barkers Structure), and a broad zone of stockwork vein hosted mineralisation
within a granophyric zone of the Power Sill Gabbro.

Drill hole Information
A summary of all information material to the understanding of the
exploration results including a tabulation of the following information
for all Material drill holes:
easting and northing of the drill hole collar


elevation or RL (Reduced Level – elevation above sea level in
metres) of the drill hole collar

dip and azimuth of the hole
down hole length and interception depth


hole length.
If the exclusion of this information is justified on the basis that the

information is not Material and this exclusion does not detract from the
understanding of the report, the Competent Person should clearly
explain why this is the case.
Refer to the various tables in the body of this report.


Exploration results that are not material to this report are excluded for some drill programmes,
however the drill physicals are all detailed for all drilling regardless of the outcome.
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.
Where aggregate intersections incorporate short lengths of high

grade results and longer lengths of low-grade results, the procedure
used for such aggregation should be stated and some typical
examples of such aggregations should be shown in detail.

The assumptions used for any reporting of metal equivalent values
should be clearly stated.
Diamond drill results are reported as aggregates across the target zone.


Aggregate intersections only use low grade results where such inclusion results in grades and
thicknesses consistent with realistic mining widths.

No metal equivalents are used.
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 orientation of target structures is well known for all in-mine exploration targets and true
widths can be accurately calculated and are reported accordingly.
Both the downhole width and true width have been clearly specified when used.
Diagrams
Appropriate maps and sections (with scales) and tabulations of
intersections 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 the figures the body of this report for the spatial context of all holes planned and drilled
to date.
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.

Exploration results that are not material to this report are excluded for some drill programmes,
however the drill physicals are all detailed for all drilling regardless of the outcome.
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.

No other material exploration data has been collected for this drill program.
