2. DRILLING ACTIVITY

2.1 Falcon

A total of 1,149m was drilled at the Falcon prospect targeting the new Starbuck structure, Podelike structures and the K2 (Table 2).

Starbuck is a high grade mineralised structure discovered at the Falcon prospect, directly west of the Pegasus deposit, in 2015. The program aimed to test for extensions to the Starbuck structure in the northern section of the Falcon prospect, which is located directly west of the Drake prospect.

FLDD16001- 003 were part of the program targeting the Starbuck structure with FLDD16002 and FLDD16003 extended to reach the K2. FLDD16001 intersected the Starbuck structure within the volcanoclastics sediments which contained visible gold with strong arsenopyrite, sphalerite and galena mineralisation.

FLDD16002 intersected a similar mineralised (arsenopyrite, sphalerite and galena) structure but on the volcanoclastic/basalt (K2A) contact as well as several Pode-like (brecciated, strongly biotite altered and arsenopyrite mineralised) structures and a mineralised K2 laminated vein with strong arsenopyrite-sphalerite mineralisation.

FLDD16003 intersected a strong structure around the K2A position but initial indications suggested little mineralisation.

2.2 Pegasus

A total of twelve diamond drill holes (2,189.13m) were drilled at Pegasus during the quarter (Table 3).

EKJV Quarterly Report – June 2016

Page 4

All drill holes targeted the Pode structure with two objectives. Firstly, the intersection of the Pode and K2B structures in the northern section of the Pegasus deposit that consistently returns very high grade intercepts with the aim to infill the zone to a 30m by 30m drill spacing and subsequently upgrade the zone to Indicated resource category. All seven drill holes intersected the Pode and K2B structures.

Secondly, specifically testing the area above the current Pode resource wireframes (where the bulk of previous drilling was RC) to determine whether the Pode structures continue up-dip towards the K2 structure, and if so, the orientation/location in that area. Three of the five drill holes intersected Pode structures, including PGDD16008, which intersected two Pode structures that contained visible gold.

2.3 Drake

Two diamond drill holes (660.3m) were completed at Drake during the quarter (Table 4).

Both drill holes targeted the K2B and K2 structures in a large area below the Drake prospect with no previous drilling conducted. A secondary aim was to intersect possible Pode-like structures in the Bent Tree Basalt.

Both drill holes intersected brecciated veining very similar to the Pode structure at Pegasus, indicating that the Pode structure does extend to the north and is not confined to Pegasus.

3. RESULTS AND INTERPRETATION

3.1 Falcon

No economic intercepts were obtained in FLDD16001 and 002 however both drill holes were strategic successes as they intersected mineralised quartz veining in the intercalated sediments (Firefly Member) of the Black Flag Formation, the primary host of the Starbuck structure in southern Falcon.

The quartz veining intersected is similar to the Starbuck structure but not as substantial. FLDD16001 contained multiple, narrow 1-10cm quartz veins with arsenopyrite mineralisation with a best assay of 4.0m @ 2.45gpt gold from 254m.

FLDD16002 contained an eight metre zone of quartz veining, sericite alteration and arsenopyrite mineralisation located on the contact between the Firefly Member and the Bent Tree Basalt (K2A structure). FLDD16002 was extended into the Drake prospect targeting the K2 structure intersecting two Pode-like structures in the Bent Tree Basalt at approximately 232m and 282m depth with intercepts of 1.15m @ 2.9gpt gold and 8.0m @ 0.89gpt gold respectively. This is another exploration success, proving Pode-like structures exist outside of the Pegasus deposit and host gold mineralisation.

FLDD16002 also intersected a 2.6m wide laminated quartz vein, the K2 structure, which returned 2.6m @ 0.82gpt gold. It is part of a wider zone of mineralisation throughout the shale, which returned 12.1m @ 0.64gpt from 574m. This indicates the K2 structure is present and of significant width below the Drake deposit and does host, albeit low grade in this specific locality, gold mineralisation.

FLDD16003 intersected quartz veining in the IVT which is likely the Falcon target. Moderate biotite-chlorite alteration and shearing could be distal part of Starbuck structure suggesting continuity of the structure to the north.

This drill hole continued on to target Drake intersecting the probable halo of a Pode-like structure at 219m and another definite Pode-like structure at 285m, proving this structure is present at Drake.

A narrow, laminated K2 vein with weak sericite alteration, arsenopyrite-sphalerite mineralisation returned 0.63m @ 1.9gpt gold from 498.37m indicating the K2 structure is present below the Drake deposit and hosts, albeit low grade, gold mineralisation.

3.2 Pegasus

PGDD16001 and PGDD16002 were designed to infill planned stope shapes and confirm the continuity of the mineralisation up dip.

PGDD16002 intersected the Pode and K2B structures 2m apart and extended the economic Pode/K2B intersection zone up dip approximately 20m with a broad intercept of 8.95m @ 7.81gpt gold from 144.38m.

PGDD16005 and PGDD16006 results suggest that the Pode/K2B intersection does not continue up-dip as far as previous interpreted with PGDD16005 intersecting the two structures one metre apart.

PGDD16004 returned a wide intersection zone of 13.43m @ 2.54gpt gold from 184m with separate Pode (1.98m @ 3.79gpt gold) and K2B (4.56m @ 2.96gpt gold) structures 2m apart.

Results for DRDD16005 and partial results from DRDD16002 drilled were received with the final results for the K2 section of DRDD16002 still pending.

DRDD16002 intersected a Pode-like quartz vein with a significant pyrite, minor sphalerite and arsenopyrite mineralisation surrounded by biotite alteration halo that returned 0.45m @ 90.84gpt gold from 82.7m.

DRDD16005 intersected a laminated K2E quartz vein with massive, vuggy pyrite, arsenopyrite, sphalerite and scheelite mineralisation assayed at 0.85m @ 9.4gpt gold. The entire shale between K2E and K2 was mineralised assaying 9.7m @ 0.56gpt gold. The K2 grade in DRDD16005 reflects the observed geology where the K2 vein was almost absent with only several 2mm wide quartz veins present.

APPENDIX 1

JORC Code, 2012 Edition – Table 1 Pegasus, Drake, Falcon

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 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.

Sampling was completed using a combination of Reverse Circulation (RC) and Diamond
Drilling (DD). RC drilling was used to drill pre-collars were 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 NQ and HQ diamond core, with a minimum
sample width of either 20cm (HQ) or 30cm (NQ).

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 for most of each hole, with 1m
samples submitted for areas of known mineralisation or anomalism.

Samples were taken to Genalysis Kalgoorlie for preparation by drying, crushing to <3mm,
and pulverising the entire sample to <75μm. 300g Pulps splits were then dispatched to
Genalysis Perth for 50g Fire assay charge and AAS analysis.
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 bitor other type, whether core is oriented and ifso, by what method, etc.).

Diamond drilling was used from surface. HQ (63.5mm) diameter core was drilled for all
resource definition holes, elsewhere both HQ and NQ (50.5mm) diameter core was drilled.

Core was orientated using the Reflex ACT Core orientation system.
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.

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 2015 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.

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.

For Raleigh Corridor, the drilling intersecting the Strzelecki Shear was drilled HQ3, to retain
any possible fault gauge that is commonly present on this structure and can contain
significant amounts of gold mineralisation. Normal HQ2 drilling has the possibility of poor
recovery of the fault gauge.
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 also taken through oriented
zones. All logging is quantities where possible and qualitative elsewhere. A photograph is
taken of every core tray.

RC sample chips are logged in 1m intervals. For the entire length of each hole. Regolith,
lithology, alteration, veining and mineralisation are all recorded.
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

All Diamond core is sawn and half core taken. Almonte core saws are used with core
boats ensuring that core is sawn strictly in half for consistent quality of sample. HQ2 sized
diamond core is the most appropriate sample for the nature of the mineralisation. The
remaining half core is stored for later use.

All RC samples are split using a rig-mounted cone splitter to collect a 1m sample 3-4kg in
size. The cone splitters are level ensuring sample quality is consistent and representative

of the whole 1m sample. These samples were submitted to the lab from any zones
approaching known mineralised zones and from any areas identified as having
anomalous gold. Outside of mineralised zones, spear samples were then taken to give a
4m composite sample.

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

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 <3mm particle size. The entire crushed sample (if less than 3kg) or sub-sample is
then pulverised 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.
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 50g fire assay charge is used with a lead flux, dissolved in the furnace. The prill is totally
digested in HCl and HNO3acids before Atomic Absorption Spectroscopy (AAS)
determination for gold analysis. This method 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 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.

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

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 a verified by another geologist during the drill hole validation
process, and later by a Competent person to be signed off

No Twinned holes were drilled for this data set

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 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 Differential GPS by the field assistants

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 or Gyro Australia, taking readings every 5m for improved
accuracy. This is done in true north.

The final collar is picked up after drill hole completion by Differential GPS in the MGA 94_51
grid.

Good 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.

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.

Drill hole spacing across the area varies. Exploration targeting is typically 100m x 100m. For
the resource definition drilling within Pegasus, spacing is typically 50m x 50m allowing the
resource to be graded as an Indicated Resource. For the Pode, drilling spacing was
approximately 30m x 30m. The HRPD drilling is more wide spaced, as this is largely
unclassified for resource reporting purposes. Spacing is wider than 160m in some areas.

These drillspacings are considered appropriatefor theMineral Resource classifications

identified.

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.

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 45°. To target these
orientations, the drill hole dips of 60-70° towards ~060° achieve high angle intersections
on all structures.

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 generally every three months.

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

All holes mentioned in this report are located within the M16/309 and M16/326 Mining

managed by Northern Star Resources Ltd (51%). The minority holding in the EKJV is held
by Tribune Resources Ltd (36.75%) and Rand Mining Ltd (12.25%).

The tenement on which the Pegasus, Drake and Falcon deposits are hosted (M16/309) is
subject to two royalty agreements; however neither of these is applicable to the Pegasus
deposit. The agreements that are on M16/309 but not relevant to the Pegasus project are
the Kundana‐Hornet Central Royalty and the Kundana Pope John Agreement No. 2602‐

HORNET-RUBICON-PEGASUS-DRAKE (HRPD)

The first reference to the mineralisation style encountered at the Pegasus 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 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.

This report is concerned solely with 2015-2016 drilling that led on from this period.
AMBITION

The Ambition target was originally defined by Goldfields Limited in 2001 from magnetic
‘anomalies’ as “a continuation of the Arctic Structure mined in the Arctic Pit to the south”
and “The second target area, a further kilometre north, is made up of medium to coarse
grained gabbro consistent with Units 4 to 6 of the Powder Sill, and a conglomeratic
sequence to the east”

Late in 2001, a total of 32 RC holes were drilled for 2332m (ARC293-ARC324). ARC296
returned 2m @ 2.67gpt from 56m in carbonaceous shale. Set depth drilling with ARC315
also intersected 2m @ 0.49gpt at the end-of-hole near where the contact is visible in
outcrop.

A magnetic high identified from the 1997 aeromagnetic data was named JH1 and
modelled in late 2002. The magnetic lineament including this anomaly was drilled with
RC holes JHRC001 to JHRC004 in early 2003, but despite the diligent modelling, the
targeted structure is offset to the west of the centre of the lineament and these holes
therefore missed the targeted contact, drilling only the footwall stratigraphy.
RALEIGH CORRIDOR

The Raleigh Corridor prospect includes the Golden Hind, Sir Walter and Wicked Witch
targets worked by Tribune Resources, Placer Dome and Barrick Gold in the past. All
targets are either the Strzelecki Structure where it juxtaposes volcanogenic wacke against
intermediate volcanoclastic rocks or the sub parallel gabbro-wacke intrusive contact.

The original diamond drilling of Golden Hind was by Tribune Resources in the late 1990s,
work which was progressed with more diamond drilling by Barrick Gold in 2005 and 2007-
8 totalling 15 diamond drill holes

Placer Dome progressed the Sir Walter zone with four diamond holes in 2004-5

Barrick Gold progressed the Wicked Witch part of the prospect with three diamond holes
in 2006

The Raleigh Corridor target in its current form was consolidated from multiple small
prospects by Barrick Gold geologists in 2012 and advanced with ten diamond drill holes
and seven RC holes. These holes returned several high grade intercepts up to around
1000 grammetres leading to the current attention given to the target.
FALCON*

The Falcon prospect defines a new exploration project formed in early 2015 and located
in the Kundana camp between the Zuleika (K2A) and Strzelecki shear zones.

In 1999 Goldfields Limited conducted a drill testing programme in the northern extent of
the prospect, the Juliet prospect, consisting of 21 RC holes and 2 diamond holes, which
targeted the K2A structure only, the current eastern border of the Falcon prospect.

Previous exploration in the prospect was minimal, consisting of regional exploration in the
form of wide spaced RAB and air core drilling in 2000 and 2002 by Goldfields Limited, and
a wide 100m spaced RC programme conducted by Barrick Gold in 2012, all focussed on
targeting the Strzelecki and Zuleika structures.

All previous exploration failed to identify the mineralisation potential in the intermediate
volcanoclastic unit, which was first discovered in several diamond drill holes drilled in early
2015totarget thewesternextents of thePegasus prospect.
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.

Strzelecki mineralisation (Raleigh Corridor) 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 (Spargoville Formation). 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.

K2-style mineralisation (Pegasus, Rubicon, Hornet, Drake, and Ambition) consists of narrow
vein deposits hosted by shear zones located along steeply-dipping overturned lithological
contacts.

At the HRPD deposits, the K2 structure is present along the contact between a black shale
unit (Centenary shale) and intermediate volcanoclastic (Spargoville formation).

At Ambition, the K2 structure has the same footwall stratigraphy as the rest of the structure
but in the hangingwall is the Powder Sill Gabbro and Volcanogenic siltstone-sandstone.

Minor mineralisation, termed K2B, also occurs between the Strzelecki and K2 shears, on

the contact between the victorious basalt and Bent Tree Basalt (both part of the regional
upper Basalt Sequence).

A 50° W dipping fault offsets this contact and exists as a zone of vein-filled brecciated
material hosting the Pode-style mineralisation.
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.

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.

See Tables 2 to 7. Drilling for the June Quarter is listed in Table 1. Significant results returned
during the quarter are listed in Tables 8 to 10.

All other information that is material to the EKJV has been reported in previous EKJV
reports.
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 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.

The assumptions used for any reporting of metal equivalent values should be clearly 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 1gpt
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.

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.

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’).

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.
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 drill
hole 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.

Metallurgical test work was conducted on 9 Pegasus samples. The results are summarised
as follows:
o
All Pegasus recoveries were above 91% for the leach tests
o
Gravity gold recovery estimated at 55%
o
Cyanide consumption 0.62 kgpt;
o
Lime 2.29 kgpt
o
Oxygen Consumption 60 gpt per hour
o
Bond Ball mill work index average 18.1 kWh/t
o
Bond Abrasion Index average 0.1522
Further work
The nature and scale of planned further work (e.g. tests for lateral extensions or depth
extensions or large-scale step-out drilling).

Diagrams clearly highlighting the areas of possible extensions, including the main
geological interpretations and future drilling areas, provided this information is not
commercially sensitive.

Further work in 2015-16 will plan to extend the indicated resource deeper by infill drilling
around Drake, Pegasus, Rubicon and Hornet. Advanced exploration work will also
attempt to upgrade an area at depth spanning 1km of strike to an inferred resource. The
continuation of the K2 trend will continue to be drill tested at depth (Figures 1 and 2
below) below Polaris and along strike of Arcas and the Link Zone.

Further work at Raleigh Corridor is not planned at this stage.

Work at Falcon is continuing, with understanding the stratigraphic sequence and
modelling. Further drilling is planned for 2016.

Further work at Ambition will consist of targeting shoot controls on current mineralisation,
most likely in FY2017.
