Commentary

Sampling techniques

Nature and quality of sampling (eg 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.

Sampling was completed using a combination of Reverse circulation (RC) and Diamond Drilling (DD). RC drilling was used to drill pre-collars for many of the Resource definition holes with Diamond tails. Diamond drilling constitutes the rest of the drilling.

Diamond core was transferred to core trays for logging and sampling. Half core samples were nominated by the geologist from both NQ2 and HQ Diamond core, with a minimum sample width of either 20cm (HQ) or 30cm (NQ2).

Sampling techniques

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Core is aligned and measured by tape, comparing back to down hole core blocks consistent with industry practice.

Criteria

JORC Code explanation

Commentary

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 (eg '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 (eg

submarine nodules) may warrant disclosure of detailed information.

Diamond drilling is completed to industry standard using varying sample lengths (0.3 to 1.2m) based on geological intervals, which are then crushed and pulverised to produce a ~300g pulp sub sample to use in the assay process.

Diamond core samples are fire assayed (50g charge), with the ore zone or any samples with observed visible gold assayed via screen fire assay method.

Visible gold is sometimes encountered in core sampling.

Drilling techniques

Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of Diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

Both RC and Diamond Drilling techniques were used. Diamond drillholes were predominantly NQ2 (50.5mm).

All resource definition holes completed post 2011 were

drilled using HQ (63.5mm) diameter core.

Core was orientated using the Reflex ACT Core orientation system.

RC Drilling was completed using a 5.75" drill bit, downsized to 5.25" at depth.

Some RC pre-collars were drilled followed by Diamond tails. Pre-collar depth was to 180m or less if approaching known mineralisation.

Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

Recovery was excellent for Diamond core and no relationship between grade and recovery was observed. For RC drilling, pre-collars were ended before known zones of mineralisation and recovery was very good through any anomalous zones, so no issues occurred.

Drill sample recovery

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

RC drilling contractors adjust their drilling approach to specific conditions to maximise sample recovery. Moisture content and sample recovery is recorded for each RC sample. No recovery issues were identified during RC drilling. Recovery was poor at the very beginning of each hole, as is normal for this type of drilling in overburden.

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.

Drill sample recovery

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.

No relationship between sample recovery and grade was identified. Diamond recovery through ore zones typically

100% No issues with RC recovery have been identified.

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.

All Diamond core is logged for Regolith, Lithology, veining, alteration, mineralisation and structure. Structural measurements of specific features are also taken through oriented zones.

RC sample chips are logged in 1m intervals. For the entire length of each hole. Regolith, Lithology, alteration,

veining and mineralisation are all recorded.

Logging

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

All logging is quantitative where possible and qualitative elsewhere. A photograph is taken of every core tray.

Logging

The total length and percentage of the relevant intersections logged.

100% of the drill core and RC chips are logged.

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.

Diamond core is routinely half core sampled. The core is cut with an Almonté Diamond core saw and half core sampled. The same half is collected to sample intervals defined by the Logging Geologist with samples not crossing geological boundaries. The remaining core is archived for future works.

All major mineralised zones are sampled, plus visibly altered material outside the ore zone into what is deemed as barren material, >5m of hangingwall/footwall.

All other structures and quartz veining that have observed alteration and/or mineralisation outside of the known orezone is sampled with up to ±5m on either side.

Ideally, sample intervals are to be 1m in length, though range from 0.30m to 1.20m in length. Total weight of each sample generally does not exceed 3kg.

Sample preparation was conducted at Genalysis 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. If the sample is greater than 3kg a Boyd crusher with

rotary splitter is used to reduce the sample size to less than

3kg (typically 1.5kg) at a nominal

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

Sub-sampling techniques and sample preparation

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

RC samples were split using a rig-mounted cone splitter on 1m intervals to obtain a sample for assay. 4m Composite spear samples were collected and submitted for analysis. After the assay results were received, any composite that exceeded 0.2g/t was re-sampled at 1m intervals and analysed.

Samples were taken to Genalysis Kalgoorlie for preparation by drying, crushing to

Sub-sampling techniques and sample preparation

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Sample preparation is deemed adequate.

Sub-sampling techniques and sample preparation

Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

Field duplicates were taken for RC samples at a rate of 1 in 20.

Sub-sampling techniques and sample preparation

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 for all RC samples (1 in 20 sample). No Field duplicates are submitted for Diamond core.

Sub-sampling techniques and sample preparation

Whether sample sizes are appropriate to the grain size of the material being sampled.

Sample sizes are considered appropriate.

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.

A 50g Fire assay charge is used with a lead flux, dissolved in the furnace. The prill is totally digested by HCl and HNO3 acids before Atomic absorption spectroscopy (AAS) determination for gold analysis.

Quality of assay data and laboratory tests

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.

Criteria

JORC Code explanation

Commentary

Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie. lack of bias) and precision have been established.

Certified reference materials (CRMs) are inserted into the sample sequence randomly at a rate of 1 per 20 samples to ensure correct calibration. Any values outside of 3 standard deviations are re-assayed with a new CRM.

Blanks are inserted into the sample sequence at a rate of

1 per 20 samples. This is random, except where high grade mineralisation is expected. Here, a Blank is inserted

after the high grade sample to test for contamination.

Failures above 0.2gpt are followed up, and re-assayed. New pulps are prepared if failures remain.

Verification of sampling and assaying

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

All significant intersections are verified by another Northern Star geologist during the drill hole validation process, and later by a Competent person to be signed off.

Verification of sampling and assaying

The use of twinned holes.

No Twinned holes were drilled for this data set.

Verification of sampling and assaying

Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

Geological logging was captured using excel templates. Both a hardcopy and electronic copy of these are stored, as well as being loaded in to the database using

automatic acquire loaders. Assay files are received in csv format and loaded directly into the database by the Database administrator (DBA). A geologist then checks that the results have inserted correctly. Hardcopy and electronic copies of these are stored. No adjustments are made to this assay data.

Data is imported directly from laboratory reports into an

Acquire database.

Hard copies of RC and core / assays and surveys are kept on site.

Visual checks are conducted as part of the validation process of the data in Datamine.

Verification of sampling and assaying

Discuss any adjustment to assay data.

Screen fire assays are used as priority over fire assays for Diamond core. Comparisons of screen fire and fire assays are completed on a hole-by-hole basis.

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.

A planned hole is pegged using a Differential GPS by the field assistants.

Underground Diamond holes are picked up by mine surveyors.

During drilling single-shot surveys are every 30m to ensure the hole remains close to design. This is performed using the Reflex Ez-Trac system. Upon hole completion, a Gyroscopic survey is conducted by ABIMS, taking readings every 5m for improved accuracy. This is done in true north.

The final collar is picked up after hole completion by

Differential GPS in the MGA 94_51 grid.

Location of data points

Specification of the grid system used.

A local grid system (Kundana 10) is used for mine based drilling. It is rotated 29.25 degrees to the west of MGA94 grid.

Exploration drilling is reported in MGA 94 grid

Location of data points

Quality and adequacy of topographic control.

Quality topographic control has been achieved through Lidar data and survey pickups of holes over the last 15 years.

Data spacing and distribution

Data spacing for reporting of Exploration

Results.

Exploration data spacing is variable, dependent on the intent of the drill program. Drillhole spacing across the areas varies from sub 20m to 300m spacing along strike.

Data spacing and distribution

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.

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 majority of the structures in the Kundana camp dip steeply (80°) to WSW. The Pode structure has a much shallower dip in a similar direction, approximately 50° . To target these orientations the drillhole dips of 60-70° towards ~060° achieve high angle intersections on all structures.

Orientation of data in relation to geological structure

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 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 Resources in a secure yard. Once submitted to the laboratories they are stored in a secure fenced compound, and tracked through their chain of custody and 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.

Sampling techniques and data handling are considered adequate.

Mineral tenement and land tenure status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding

royalties, native title interests, historical sites, wilderness or national park and

environmental settings.

The reported drilling is located within the M16/309 and M16/326 Mining leases and are held by The East Kundana Joint Venture (EKJV). The EKJV is majority owned and managed by Northern Star Resources Limited (51%). The minority holding in the EKJV is held by Tribune Resources Ltd (36.75%) and Rand Mining Ltd (12.25%).

Mineral tenement and land tenure status

The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

No known impediments exist and the tenements are in good standing.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties.

The first reference to the mineralisation style encountered at the K2 project was the mines department report on the area produced by Dr. I. Martin (1987). He reviewed work completed in 1983 - 1984 by a company called Southern Resources, who identified two geochemical anomalies, creatively named Kundana #1 and Kundana #2. The Kundana #2 prospect was subdivided into a further two prospects, dubbed K2 and K2A.

Between 1987 and 1997, limited work was completed. Between 1997 and 2006 Tern Resources (subsequently

Rand Mining and Tribune Resources), and Gilt-edged mining focused on shallow open pit potential which was not considered viable.

In 2011, Pegasus was highlighted by an operational review team and follow-up drilling was planned through

2012.

A small drill programme of four RC holes targeted the K2 structure at Ambition in 2003. These holes failed to intersect the structure, presumably due to an offset of the aeromagnetic lineament. Other drilling in the area has absent or poor quality geological logging. The 2003 drillholes assisted in successfully intersecting the target in this drill programme, but beyond that, historical drilling provides little value in appraisal of the K2 structure at 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.

K2-style mineralisation (Pegasus, Rubicon, Hornet) consists of narrow vein deposits hosted by shear zones located along steeply-dipping overturned lithological contacts. The K2 structure is present along the contact between a black shale unit (Centenary shale) and intermediate volcaniclastics (Spargoville formation).

Minor mineralisation, termed K2B, also occurs further west, on the contact between the Victorious basalt and Bent Tree Basalt (both part of the regional upper Basalt Sequence).

A 45° W dipping fault offsets this contact and is characterised by a zone of vein-filled brecciated material hosting the Pode-style mineralisation.

In the northern part of the Ambition target, the hangingwall basalts are absent and the structure separates a gabbro and lithic gritstone from Spargoville Volcaniclastic rocks. Although it is unclear at this stage, the current interpretation is that the target structure in the northern part of the Ambition prospect is actually the confluence of the Strzelecki and K2 structures thus the basalt sequences are faulted out where the two

structures converge.

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:

o easting and northing of the drill hole collar

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

o dip and azimuth of the hole

o down hole length and interception depth

o hole length.

Details of all drilling for the quarter listed.

Drill hole

Information

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.

No material information has been excluded.

Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

All reported assay results have been length weighted to provide an intersection width. A maximum of 2m of barren material between mineralised samples has been permitted in the calculation of these widths.

No assay results have been top-cut for the purpose of this report. A lower cut-off of 1g/t has been used to identify significant results, although lower results are included where a known ore zone has been intercepted, and the entire intercept is low grade.

Data aggregation methods

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.

All reported assay results have been length weighted. Aggregations of reported intersections take into account geological boundaries (eg. Laminated quartz veining) and continuity of mineralisation.

Data aggregation methods

The assumptions used for any reporting of metal equivalent values should be clearly stated.

No metal equivalent values have been used for the reporting of these exploration results.

Relationship between mineralisation widths and intercept lengths

These relationships are particularly important in the reporting of Exploration Results.

True widths have been calculated for intersections of the known ore zones, based on existing knowledge of the nature of these structures.

Both the downhole width and true width have been clearly specified when used.

Relationship between mineralisation widths and intercept lengths

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

Due to varying intercept angles the true thickness is manually estimated on a hole by hole basis. Both true width and downhole lengths are reported.

Relationship between mineralisation widths and intercept lengths

If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

Reporting of results includes the downhole and true width of the mineralised section.

Diagrams

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.

Appropriate plans and section have been included in the body of this report.

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.

Both high and low grades have been reported accurately, clearly identified with the drillhole attributes and 'From' and 'To' depths.

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.
