Project Status Definitions
PROJECT STATUS DEFINITIONS
Grassroots Exploration Opportunities
This category is for exploration tenements with identified
prospectivity, but with little or no drilling undertaken.
Early exploration
This project is at a preliminary stage of investigation. While the
company might have reported some exploration results, the
information is not yet sufficient to estimate the size of a Mineral
Resource according to the JORC Code.
Exploration results have been sufficient to estimate a Mineral
Resource or Ore Reserve according to the JORC Code.
Advanced exploration
Project development
Having defined Mineral Resource or Ore Reserve according to the
JORC Code, the company is now undertaking studies and/or seeking
approvals to determine whether the project can feasibly be developed
into an operating mine.
PROJECT DEVELOPMENT DEFINITIONS
Scoping study
A scoping study is a preliminary economic and technical study to understand the approximate economics and
viability of various development options for the mining and treatment of a mineral deposit. It will involve a
conceptual or preliminary mine plan and is used as the basis for determining whether to proceed to more
detailed studies. Scoping studies are developed copying plans and factoring known costs from existing similar
projects completed elsewhere and are accurate to within plus or minus 35-50%.
Feasibility Studies
A Preliminary Feasibility or “Pre-Feasibility Study” (PFS) is more detailed than a Scoping Study. A Pre-Feasibility
Study is used in due diligence work, determining whether to proceed with a Definitive Feasibility Study and as a
“reality check” to determine areas within the project that require more detailed attention. Pre-Feasibility Studies
are done by factoring known unit costs and by estimating gross dimensions or quantities once preliminary
technical, engineering and mine design has been completed. Pre- Feasibility Studies are generally accurate to
20-30%.
A Definitive Feasibility Study (DFS) is the most detailed study and will determine definitively whether to proceed
with the project. A Definitive Feasibility Study requires a high level of technical, engineering and design work as
well as detailed capital and operating budget figures for the project. Definitive Feasibility Studies are accurate to
within 10-15%.
A Bankable Feasibility Study (BFS) is a Definitive Feasibility Study, with a focus on financial and budget aspects,
that is presented to financiers to obtain project financing. It is also accurate to within 10-15% depending on the
requirements of the financial institution.
OTHER DEFINITIONS
JORC Code
The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves is called ‘the
JORC Code’.
The JORC Code is a professional code of practice that sets minimum standards for Public Reporting of minerals
Exploration Results, Mineral Resources and Ore Reserves.
The JORC Code provides a mandatory system for the classification of minerals Exploration Results, Mineral
Resources and Ore Reserves according to the levels of confidence in geological knowledge and technical and
economic considerations in Public Reports.
Any Public Reporting of Exploration Results, Mineral Resources or Ore Reserves must be signed off by a
Competent Person in accordance with the JORC Code.
A Competent Person must be a Member or Fellow of The Australasian Institute of Mining and Metallurgy, or of
the Australian Institute of Geoscientists, or of a ‘Recognised Overseas Professional Organisation’ (the 2004
Edition) or ‘Recognised Professional Organisation’ (2012 Edition).A Competent Person must have a minimum of
five years’ experience working with the style of mineralisation and type of deposit under consideration and
relevant to the activity which that person is undertaking.

HISTORY OF PROJECT AREA
History of Jervois Exploration and Mining
Following the discovery of weathered outcrops of base metal mineralisation at Jervois in 1929,
some small-scale mining of near-surface oxidized ore took place with handpicked ore
transported initially to smelters in South Australia and later to Mt Isa in Queensland for
treatment.
Figure 1 Bellbird historical workings
The first systematic exploration at Jervois was undertaken by New Consolidated Goldfields
(Australasia) Pty Ltd in the period 1961-1965; subsequently, exploration programmes were
carried out by: Petrocarb Mineral Exploration (SA) Pty Ltd (1969-1973) then by a joint venture
between Petrocarb and Union Corporation (Australia) Pty Ltd (19731974); Plenty River Mining
alone (1980-1983) and then in joint venture with Anaconda (1983-1984) and later with
Normandy Poseidon (1991-1996); Britannia Gold NL alone (1997-1999) and in joint venture
with MIM Exploration Pty Ltd (1999-2001).
Exploration by the above companies identified massive and disseminated sulphide
mineralisation at a number of localities within a particular unit of a metamorphosed,
predominantly sedimentary sequence, which can be traced discontinuously in outcrop around
the ‘J-fold’. The main deposits with surface expression that were delineated are from the north:
Reward, Marshall and Green Parrot on the eastern limb of the J-structure and Bellbird on the
Updated September 2014

Base Metals
short western hook of the ‘J’. Other poorly tested zones of base/precious metal sulphide
mineralisation are located at Pioneer, North Reward, Sykes and Cox’s Find on the stem of the
‘J’ and at Rockface, Rockpool, Killeen Zinc and Killeen Copper on the curve of the ‘J’ (Figure
16). Petrocarb Mineral Exploration also drill tested six separate zones of scheelite
mineralisation associated with calc-silicate rocks; scheelite is an ore of tungsten. During the
period from 1961 to 2001 an estimated 320 percussion and diamond holes were drilled at
Jervois, including 50 holes drilled for open pit planning and ore definition purposes at the shortlived Green Parrot mine and some 45 holes drilled to test the scheelite occurrences and
mineralisation off the ‘J-structure’. Each of the previous explorers added to the geological
knowledge of the area.
Plenty River Mining undertook the only significant mining at Jervois. In 1981 that company
commissioned a treatment plant and mine infrastructure to exploit high-grade silver-lead-zinccopper ore from the Green Parrot deposit. In five months of production during 1982 and 1983,
the plant produced 2,000 tonnes (t) of concentrate grading 50.4% lead, 5.4% zinc, 0.6%
copper and 680 gram/tonne (g/t) silver. Mining was suspended in December 1983 due to a
sharp metal price fall. It is reported that total production of ore from the Green Parrot open cut
was 44,000t grading 1.5% copper, 8.5% lead, 2.5% zinc and 160g/t silver.
Figure 2 Remnants of Plenty River Mining Plant
MIM Exploration Pty Ltd also conducted metallurgical test work on samples from two drill holes
(J25 and J27) at the Reward deposit, in order to gain a preliminary indication of the likely
recoveries obtainable from a conventional treatment plant. The results show the mineralisation
is free milling and concentrates sufficiently well to achieve a +28% copper concentrate at
better than 90% recovery.
When Reward Minerals assumed control of the Jervois Project in April 2004, they began the
first of a series of drilling campaigns aimed at investigating the established prospects in detail,
as well as extending exploration to other parts of the large tenement holding to identify
additional prospects. By the end of 2004, 44 RC drill holes (some with diamond core tails) for
4,361m had been completed with the majority of holes directed at the Bellbird, Green Parrot,
Reward and Marshall deposits. As a result of the then intense activity nationwide in the mining
industry, exploration drilling was hampered by the difficulty in finding a contractor with a
suitable drill rig willing to work in this remote area; there was no opportunity to drill any holes in
2005 but the situation later improved somewhat and 39 holes (for 3,843m) were drilled in 2006,
18 holes (for 2,327m) were drilled in 2007, 40 holes (for 6,285m) in 2008, and in 2009, 20
holes (for 3,426m). Five of the RC holes drilled in 2009 are pre-collars to be completed by
diamond coring to test the Reward and Bellbird deposits at vertical depths of 300 - 400m.
In 2011 Jinka Minerals conducted a Sub-audio Magnetics (SAM) survey to help identify the
structures that were controlling mineralisation within the prospective stratigraphy.

CURRENT PROJECT STATUS
Geology
The Jervois mineralisation is contained within the Lower Proterozoic Bonya Schist Formation
(1807Ma), which has been folded to form a J-shaped, near isoclinal and steeply northplunging, synform. The more resistant lithologies crop out as a series of hills that prominently
define the J-structure on aerial photographs and satellite images. This distinctive J-shape of
the Bonya Schist outcrop in the project area has been interpreted as the result of re-folding of
Updated September 2014
Northern Territory Mineral Investment Opportunities

Base Metals
pre-existing folds and also as a drag feature to a regional fault that passes to the west.
In the Jervois area, the Bonya Schist is interpreted to be derived from a thick sequence of
argillaceous to arenaceous sediments with intercalations of limestone that suggest a shallowmarine environment of deposition. Dominant lithologies are now sericite, cordierite, and
andalusite or chlorite schist with subordinate biotite-feldspar schist, calc-silicate rock,
carbonate rock, amphibolite, magnetite quartzite, massive garnet rock, and quartz-tourmaline
rock. Pervasive magnetite, ranging in content from two to twenty percent, extends the length of
the J-fold and to the east and north. This mineral is largely responsible for the distinct magnetic
signature that reproduces the J-shape of the outcrop pattern on aeromagnetic maps.
Magnetite also preferentially replaces bedded calc-silicate rocks to produce massive ironstone.
The regional metamorphic grade ranges from upper greenschist to middle amphibolite facies.
The schistose sequence is unconformably overlain to the west and northwest by the Georgina
Basin sediments of Upper Proterozoic to Devonian age, which form the Jervois Range.
The region has experienced a long and complex structural history and detailed structural
mapping has revealed three major deformational events in the Jervois area. Bedrock over
much of the area is covered by soil and shallow alluvium with outcrop restricted to the low hills.
The calc-silicate and carbonate-rich lithologies in particular, tend to be silicified and more
resistant to weathering and erosion. Rapid changes in rock types and tight isoclinal folding add
to the difficulties of geological mapping and only broad correlations are possible within the
project area.
PROPOSED FUTURE ACTIVITIES
We are currently working on a pre-feasibility study which is due for completion in November
2014. The study is investigating a 2 million tonne per annum flotation plant producing
approximately 100,000 tonnes of copper concentrate per year at a grade of 25% Cu.
A drilling programme is currently underway to infill and upgrade the resource further.
DETAILS OF RESOURCES
The total resource at Jervois is 25.3million tonnes at a grade of 1.14% Cu and 22 g/t Ag as
detailed in the table below.

RECENT EXPLORATION HIGHLIGHTS
Exploration to date at Mount Hardy has included a HELITEM survey, field mapping and
sampling, ground EM surveys, RC drilling, IP, DHEM and diamond drilling and has highlighted
the presence of surficial and sub-surface copper, lead and zinc mineralisation within the
tenement area.
A 2100m diamond drill program carried out in March 2013 investigated both the geophysical
and geological targets identified in previous exploration.
Mount Hardy Prospect
The Mount Hardy prospect is defined as a 1km x 500m hill with broad oxide copper
mineralisation exposed at surface. Three sections were drilled to target depth extensions to the
strong surface copper mineralisation outlined in 2012. A total of four holes (13MHDDH001 to
13MHDDH004) were drilled on these sections. All holes were drilled towards the SSE (azimuth
150 degrees) and 45-60 degrees dip. Significant drill results include:
13MHDDH001
x 11.0m at 0.87% Cu from 70m down-hole, including:
o 1.0m at 4.21% Cu from 71.4m down-hole; and
o 1.0m @ 1.63% Cu from 73.8m; and
o 0.8m @ 1.05% Cu from 76.5m.
13MHDDH002
x 10.3m at 1.35% Cu from 114.7m down-hole, including:
o 0.9m @ 6.06% Cu from 118.5m;
o 0.8m @ 2.93% Cu from 117.7m;
o 0.6m @ 1.97% Cu from 119.4m; and
o 1.0m @ 1.96% Cu from 114.7m.

o 0.60m @ 2.92% Cu and 1.15g/t Au from 45.40m
x 3.10m @ 1.86% Cu from 61.90m, including:
o 1.00m @ 4.50% Cu and 0.40g/t Au from 62.50m
13MHDDH004
x 6.0m @ 0.54% Cu from 108.0m downhole
o 0.5m @ 0.48 g/t Au from 109.7m down-hole, and
o 1.0m @ 9.44 g/t Au from 112.0m down-hole
The presence of gold grades in excess of 9g/t Au, together with fresh hypogene copper
mineralisation, is considered to be very encouraging.
Browns Prospect
The Browns prospect is defined by both a 500m zone of surface copper oxide mineralisation
and an adjoining significant IP anomaly. Holes 13MHDDH005 to 13MHDDH009 were drilled at
the original Browns Prospect, which was outlined by mapping and sampling conducted by TNG
in late 2012.
Holes were drilled on two sections, targeting depth extensions to the surface mineralisation
below a large outcropping quartz vein with significant malachite (copper oxide), and an area of
old workings. Sampling in this area in late 2012 returned rock chip ICP results of up to 38.9%
Cu. Significant drill results include:
13MHDDH005
x 5.0m @ 0.58% Cu from 60.0m down-hole, including
o 1.0m @ 1.01% Cu from 62.0m down-hole; and
x 0.5m @ 1.39% Cu from 63.0m down-hole; and
13MHDDH008
x 5.4m @ 0.62% Cu from 14.5m down-hole.
A diamond hole designed to test the IP anomaly outlined just to the south of the Browns
Prospect (13MHDDH015) returned the most significant results to date. This hole intersected a
broad zone of mineralisation with outstanding zinc grades and strong copper and lead values:
x
13.0m @ 1.17% Cu, 1.82% Zn and 0.46% Pb from 74m down-hole, including
o 1.0m @ 3.86% Cu, 11.75% Zn, 2.09% Pb from 77m down-hole
Blind at surface and plunging to the WNW there is significant potential for more mineralisation
within this feature and further drilling is required to define this. A step out/extensional IP survey
is currently underway.
EM Target 1
Holes 13MHDDH010 and 13MHDDH011 were drilled to test significant HELITEM conductors
outlined at EM Target #1 and confirmed by RC drilling and subsequent DHEM surveying.
13MHDD010 successfully pierced the conductor where a broad zone of high grade Cu-Zn-PbAg mineralisation was intersected returning 21.0m @ 0.46% Cu, 3.5% Zn, 1.91% Pb and 36 g/t
Ag, from 211m down-hole. Individual samples within this zone returned maximum values of
1.88%Cu, 12.05% Zn, 7.25% Pb, and 130g/t Ag.
Diamond drill-hole 13MHDDH011 targeted a strong off-hole EM conductor defined from DHEM.
A small zone of multi-element mineralisation was intersected with maximum results of 0.1% Cu,
3.5% Zn and 1.2% Pb.
Additional DHEM is currently underway to identify the mineralised trend and locate further
targets for drilling.

EM Target 2
Diamond drill hole 13MHDDH012 was designed to test the off-hole EM conductor outlined from
hole 12MHRC002. The conductor was successfully pierced and intersected significant base
metal sulphides over a 25m interval, including maximum values of 5.9% Cu, 10.5 % Zn, 3.4%
Pb and 55 g/t Ag.
The intersections in the three holes define a plane dipping steeply to the north-west, parallel to
and just above the modelled plate. This mineralisation has now been outlined over a 50 x 50m
zone and is open in all directions.
This anomaly requires further DHEM and drilling.
EM Target 4
Hole 13MHDDH013 at EM Target 4 tested the off-hole plate modelled and interpreted from hole
12MHRC003 (which was designed to test the ground EM modelled plate), and intersected the
plate in the lower central area. Results included 1.0m @ 2.0% Cu, and DHEM will determine if
further drilling is required.
Mount Hardy IP Anomaly
Hole 13MHDDH014 was designed to intersect the down plunge portion of the IP anomaly at
Mount Hardy. Significant mineralisation had already been outlined in the up-dip position of the
IP anomaly in holes 13MHDDH001 through 13MHDDH004.
Minor mineralisation was intersected in this drill hole, with 6.0m @ 0.7% Cu, including 1.0m @
2.0% Cu. The IP anomaly remains open and will be further assessed by down-hole geophysical
methods.
Relogging of BMR 1968 Drillcore
Re-logging and sampling of BMR diamond drill core from 1968 has also highlighted the extent
of mineralisation at Mount Hardy as well as confirming the distribution and type of supergene
and hypogene mineralisation. Best intersections are summarised in Table 2.

Petrographic descriptions of both the diamond core and the RC chips from the recent
programme have provided valuable information into the sulphide/mineralisation assemblage,
genesis and the nature of the host. Both the surrounding schist and mineralised hydrothermal
quartz have experienced multiple stages of tectonism and metamorphism with associated
quartz-sericite-pyrite alteration. The analysis suggests a hydrothermal mineralisation
assemblage with possible granitic affinities.
Additional EM targets identified in the 2012 HELITEM survey are currently being tested with IP
geophysical surveys, along with additional DHEM on diamond holes drilled during 2013. The
exploration to date has resulted in the generation of multiple targets for continued investigation
during the 2014/15 field program.
BUSINESS DEVELOPMENT PLAN
This project is emerging as a large-scale, polymetallic-style project requiring significant further
exploration. Detailed assessment and evaluation of all prospects will continue to take place with
the aim of a maiden resource by the end of 2014. Metallurgical assessment of the reserve and a
scoping study is planned for 2015.
