sampled
• High-grade mineralisation intersected over the entire 700m of strike drilled to date
• 7,000m of recently defined soil anomalies yet to be tested
• Only 1,500m of strike covered with IP, with multiple undrilled anomalies immediately along strike from known
mineralisation

6.0 GEOLOGY
• Multiple lenses of outcropping stratiform mineralisation mapped at surface over ~750 metres of strike
• Lenses predominantly located in argillites at interface with volcanics
• Lenses are sub-vertical; dipping slightly to the north
• Until recently, the majority of mineralisation was understood to be contained within Lenses 4, 5 and 6
– where previous exploration was focused

8.1 DISCOVERY AT THE LENSE 7/8 TARGET
Eastern extension of
the MALM anomaly is
yet to be drill tested
• 7 holes drilled to evaluate a previously undrilled
discrete IP anomaly between Lenses 7 and 8
• A strong undrilled 200m long mise-a-la-masse anomaly
was also evident in 1999 data
• Multiple parallel lenses of high-grade
mineralisation intersected in drilling
Exploration results include:
• 14.1m @ 9.9% Cu from 134.6m
• 3.5m @ 9.3% Cu from 72.9m
• 2.0m @ 13.9% Cu from 79.4m
• 3.7m @ 7.3% Cu from 39.0m
• 1.9m @ 10.8% Cu from 116.0m
• 1.8m @ 10.4% Cu from 30.4m
• 6.4m @ 2.8% Cu from 173.3m
• 5.1m @ 2.1% Cu from 201.4m
• 2.0m @ 5.2% Cu from 24.0m
All drilling superimposed upon image of 1999 mise-a-la-masse data at Lense 7/8
• Eastern extension of the mise-a-la-masse anomaly
is yet to be drilled – this is a very high priority
expansion target
Drilling at the Lense 7/8 Target
during September 2015
Page 13
8.1 DISCOVERY AT THE LENSE 7/8 TARGET
• To date only 7 holes have been
drilled on 4 fences spaced ~40m
apart
• Remains significantly
underexplored
• Initial interpretation is that
mineralisation “pinches and
swells”
• Mineralisation remains open
along strike in both directions
and at depth
• Considerable additional highgrade tonnes already
discovered
• Further drilling will be
undertaken

8.2 DISCOVERY BETWEEN LENSES 3 AND 4
• Minimal and only very shallow drilling had previously been
undertaken in the 200m corridor between Lenses 3 and 4 (most
recently in 1965)
• With the limited data, these two lenses were previously thought
to be disconnected
New
mineralisation
at the Lense
7/8 Target
Lense 3
New
mineralisation
between Lenses
3 and 4
• CD15-26 was drilled to evaluate this corridor:
Multiple intersections of high-grade mineralisation, including:
• 2.2m @ 7.8% Cu from 112.8m
Lense 4
• 1.8m @ 8.9% Cu from 118.6m
• 1.4m @ 1.8% Cu from 138.7m
Lenses 5
and 6
• 1.1m @ 5.7% Cu from 143.8m
• 1.4m @ 1.4% Cu from 202.8m
Continuity between Lenses 3 and 4 would be very significant:
Lense 2
• More tonnes to mine
• Mineralisation is high-grade
• Mine development capital would be optimised

Page 15
8.3 DISCOVERY AT LENSE 2
• A strong IP anomaly coincides with irregularly
outcropping mineralisation over 200m
• Never previously drilled
• 9 new holes drilled over ~150m of strike
Multiple intersections of high-grade
mineralisation, including:
• 3.4m @ 4.8% Cu from 51.6m
• 10.0m @ 1.6% Cu from 62.5m
• 1.8m @ 8.9% Cu from 118.6m
• 8.7m @ 1.7% Cu from 54.3m
• 3.5m @ 1.9% Cu from 67.9m
• Mineralisation intersected at >200m depth
Drilling CD15-04, July 2015
• Mineralisation probably “pinches and swells”
• Further drilling will be undertaken

9.0 EXPLORATION POTENTIAL
• >15km of the prospective sedimentary
sequence lies within the Project
• Multiple copper occurrences along this
corridor
• No drilling outside the 700m strike that
has been drill tested to date
• 95% of the strike remains undrilled
• Mineralisation remains open at depth
• Second deepest hole on the Project
intersected:
15.4m @ 7.0% Cu (~260m below surface)

9.1 IP IS A VERY EFFECTIVE PREDICTOR
• Coventry reprocessed the 1999 IP data in April 2015 – it showed known mineralisation closely
coincides with distinct IP anomalies
• So new IP data were acquired over 1,500m of strike during June/July 2015
Page 18
9.2 DRILL-READY IP TARGETS
• 4 very-high priority undrilled IP
targets remain:
• Menel Target
• Guardian Target
• Lense 9 Target
• Lense 3 Target
• All in close proximity to, and interpreted
to be probable extensions of, the veryhigh grade mineralisation intersected
recently at the Lense 7/8 Target
• Strong copper-in-soil anomalies
coincide with all of these targets
• Rock chips assaying up to 16.5% Cu
were returned from the Guardian
Target recently

9.3 THE MENEL TARGET
• A strong IP anomaly
immediately along strike from
the Lense 1 and Lense 7/8 IP
anomalies – both of which are
associated with very highgrade mineralisation
• Completely undrilled
• IP anomaly lies within a
distinct coincident >1,300m
long undrilled copper-in-soil
anomaly
• Rock chips to 9.1% Cu have
been returned from within this
soil anomaly

Targets – showing the chargeability of the modelled source of IP anomalies, 50 and 200 metres below the surface
respectively, together with previous (white text boxes) and recent (yellow text boxes) drilling results in the vicinity.
Page 20
9.4 COPPER-IN-SOIL TARGETS
• >600 new soil samples
collected recently over 7,000m
of strike
• Extensive copper anomalism
evident
• Indicates that the Caribou
Dome Deposit may be much
bigger:
• Only 700m of a coincident
2,000m long soil anomaly
drill-tested to date
• Rock chips up to 16.5% Cu
returned recently from followup at the Guardian Target
• Further exploration at multiple
other soil anomalies is being
planned
• Further IP surveying will be
undertaken
Page 21
10.0 PRELIMINARY MINE DESIGN WORK
• Evaluating development of a moderate-sized, very high-grade, low
CAPEX/OPEX initial mining operation
• Average grade of all drill core samples >0.5% = 5.8% Cu,
so head-grade may be +4% Cu
• Possibly mining/processing 400,000–800,000 tpa
Mining Studies
• Geological model is currently being refined to include all new drill
assay results
• Initial block model of the mineralisation and grade distribution will
then be generated
4630 level adit at the Caribou Dome Copper Project.
• Initial mining studies will then be undertaken, including evaluation
of open pit and underground methodologies
Metallurgical Studies
• 70kg of representative ¼ core samples from 2015 drilling have been
collected from across the Deposit
• Samples are currently being transported to a laboratory for further
metallurgical testwork
Initial Economic Evaluation
• A preliminary evaluation of potential economics will be undertaken
following completion of the mining and metallurgical studies
• Given the thick, shallow and very high-grade of some of the
mineralisation, scheduling is expected to have a positive impact on
project economics
Second
deepest hole
on the Project
• Results will be used to guide planning for further exploration
Page 22
10.1 HISTORIC METALLURGICAL TESTWORK RESULTS
• Most recent metallurgical testwork was undertaken on a
225kg bulk sample (6.7% Cu) in 2009:
Conventional Flotation
• 82-85% recoveries were achieved to produce concentrates
grading 17.4-19.3% Cu
• Recoveries up to 90.8% have been achieved during previous
conventional flotation testwork, with concentrates grading >20% Cu
• Consultants have recently confirmed that modern methodologies
provide multiple viable processing alternatives
• New tests to be undertaken on representative samples from
across the 700m of strike drill-tested to date
Drill core from CD15-14 (Lense 7/8 Target) – containing
>16% Cu
Page 23
11.0 FURTHER EXPLORATION
2015 exploration program has been extremely successful:
3 new discoveries in past 3 months
• Economic thicknesses of very high-grade mineralisation
intersected over 700m of strike
• Mineralisation remains open in both directions along strike and at
depth
• Second deepest hole drilled at the Project intersected
15.4m at 7.0% Cu ~260m below surface
• Geological model has been refined
• Grade of mineralisation increasing to the northeast
• Four very high-priority undrilled but drill-ready IP targets
immediately adjacent to the very high-grade mineralisation in
the northeast
Looking NE from outcropping mineralisation at Lense 6
(foreground) to trenching at Lense 3 (background)
• >13km of the prospective sediment-volcanic contact present
further to the northeast
• Multiple Cu occurrences identified previously along this trend
• Multiple strong Cu-in-soil anomalies evident over >7,000m
in new data (and no soil sampling over the remainder)
• But negligible exploration undertaken previously
• IP has proven to be very effective – so IP coverage will be
extended significantly to the northeast
• Further drilling is being planned
Lenses 3, 4, 7, 8 and 9
drilled to ~120m below
surface and open at
depth and to the north
Lense 6 drilled to
~290m below surface
and open at depth
Lense 2 drilled
to ~150m below
surface and
open at depth
and to the
