KGL increases and upgrades copper, silver, lead and zinc
Resources at Jervois, NT
Highlights of Resource Update
21% increase in Total Resource to 30.5Mt
36% increase in Indicated Resources to 11.5Mt
17% increase in contained copper to 327,000 tonnes
26% increase in contained silver to 22.6Moz
59% increase in contained lead‐zinc to 190,000 tonnes
KGL Resources Limited (KGL) announces that the global resource at Jervois in the Northern Territory
has been increased by 21% to 30.5 Mt @ 1.07% copper and 23.0 g/t silver for a total of 327,000
tonnes of contained copper at a cut off of 0.5% copper and 22.6 million ounces of contained silver
as detailed in Table 1. This includes 10.6 Mt @ 1.37% copper for 146,000 tonnes of contained
copper at Marshall‐Reward and 5.4Mt @ 1.62% copper for 88,000 tonnes of contained copper at
Bellbird at a cut off of 0.75% copper.
The Resource Update follows a recent drilling program to increase and upgrade the resource. The
drilling has been central to the current work of optimising the Pre‐Feasibility Study as KGL moves
towards the development of Jervois as a significant copper, silver and multi‐metal mine.
A specific objective of the drilling was to upgrade the resources within the proposed open pit
boundaries to increase confidence in the material to be delivered to the mill in the early years of
operation. This has been successfully achieved with a 36% increase in total Indicated Resources.
Included is a substantially higher level of increase in the indicated category of lead‐zinc resource by
0.7Mt to 1Mt due mostly to infill drilling at the Green Parrot deposit.
With recent metallurgical test work confirming that good recoveries could be achieved for lead and
zinc at Jervois, this type of mineralisation was also targeted by the recent drilling. The lead‐zinc
resources increased by 70% from 2.2Mt to 3.8Mt with the Green Parrot resource increasing from
1.1Mt to 1.9Mt and the high‐grade Reward lead‐zinc resource increasing by 0.5Mt.
A number of mineral occurrences parallel to and along strike from Marshall‐Reward were tested
including Sykes and Johannsen. This near surface mineralisation has the potential to provide
additional low cost, open cut mining material though typically at a lower grade to the main copper
resources.

KGL Resources Managing Director Simon Milroy commented: “We are very pleased with the
progress made in the priorities we set for our drilling program ‐
To upgrade the confidence in the resource for those critical first few years of mine life, and
To increase the resource by step out drilling from earlier high grade intercepts,
so that we can begin to assess the true potential of the Jervois project.”
“The drilling program assessed the potential of several zones of shallow mineralisation at other
new prospects that had the potential to provide low cost open pit material to the mill. Some of
these new zones, previously fell within the planned pit outlines and hence were previously
classified as waste.”
“The PFS announced last December found Jervois to be a viable project. We
confidently expect the optimised PFS to be completed in October to result in
further improved economic parameters and considerably increased free
cash flow.
“There is clearly the prospect of more discoveries at Jervois. We expect the recently completed
3DIP survey will define the potential for near surface mineralisation in new areas that have not
previously been explored. “
The new Exploration Potential of the larger deposits identified by H&S Consulting consists of areas
peripheral to the current Inferred Resources within the interpreted mineral wireframes,
unconstrained by depth. This is estimated to be a combined total for Marshall‐Reward, Bellbird
and Green Parrot of 4–8 Mt @ 0.8 to 1.2% copper and 7 to 15g/t silver at a 0.5% copper cut off
(40,000 to 100,000 tonnes copper and 1.5 to 5 Mozs silver) (See Figures 1 and 2). The resources are
open at depth and there is additional potential along strike.
The potential quantity and grade of the Exploration Potential is conceptual in nature and there has been
insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the
determination of a Mineral Resource.

A global gold resource is 21.4Mt @ 0.16g/t for 113,000ozs at a copper cut off of 0.5% (Table 2).
The gold resource has not been updated since the Sept 2014 estimate. Validation of gold assays
from 2015 drilling are pending. Updating of the gold resource will be completed when this is
finalised.
Gold grades have been included in the resource estimates though the amount of historical gold
data is limited and as a result the gold resource estimate is classed as Inferred.

Geology & Mineralisation
The Jervois deposit has been characterised as a hybrid SEDEX‐VHMS deposit by both CSIRO and an
independent study conducted by the NTGS in 2014. Characteristics observed at Jervois that are
consistent with this style of mineralisation include:
Cu‐Pb‐Zn mineralisation is stratiform and extending over several kilometres along strike
with repeating stratigraphy due to folding
Mineralisation occurred syngenetically as a hydrothermal exhalative event, prior to
metamorphism and deformation
The sedimentary host rocks and mineral zonation suggest a SEDEX deposit, while high Cu
grade is more common in VHMS deposits.
The mineralisation is hosted by a sequence of meta‐sediments (schists) comprising siltstone,
mudstone, sandstone with lesser limestone that have been strongly deformed and display a well‐
developed foliation. Proximal to mineralisation there is a characteristic alteration that may include
silica, magnetite, garnet, chlorite and epidote. The host sediments and sulphide lenses have been
folded to form the distinctive ‘J‐Shaped’ Jervois Range.
The Jervois Project comprises six main areas of economic interest, namely Marshall‐Reward, Green
Parrot, Bellbird and Bellbird North, Rockface and Cox’s Find. Each area has sufficient drilling for the
identification of a mineral resource. Bellbird (Cu), Rockface (Cu) and Cox’s Find (Cu) are essentially
copper (+silver) deposits, while the Marshall‐Reward deposit is predominantly copper/silver with
some lenses of high grade lead/zinc mineralisation adjacent to or interleaved with the copper
mineralisation. Those deposits that exhibit a more polymetallic nature include Green Parrot,
Bellbird North and the southern part of the Bellbird East deposit. A location map of the deposits
with the regional geology is shown in Figure 3.
Next Steps
The updated resource block models are now being used as the basis for the pit optimisation and
mine design. This will lead to an updated mine schedule to be used in the optimised pre‐feasibility
study to be completed in October.
The results of the 3DIP survey are expected to be finalised in the next few days. Drill testing of the
anomalies generated in the 3DIP survey will commence shortly.

JORC CODE, 2012 EDITION – TABLE 1
1.1 Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria
JORC Code explanation
Commentary
Sampling
techniques
Diamond drilling and reverse circulation
(RC) drilling were used to obtain samples
for geological logging and assaying.
RC drill holes are sampled at 1m intervals
and split using a cone splitter attached to
the cyclone to generate a split of ~3kg.
Diamond core was quartered with a
diamond saw and generally sampled at 1m
intervals with shorter samples at geological
contacts.
RC samples are routinely scanned with a
Niton XRF. Samples assaying greater
than 0.1% Cu, Pb or Zn are submitted for
analysis at a commercial laboratory.
Other sampling techniques may have been
used prior to KGL Resources involvement
in 2011.
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.
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 (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.
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).
RC Drilling was conducted using a reverse
circulation rig with a 5.25” face-sampling
bit. Diamond drilling was either in NQ or
HQ drill diameters.
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.
RC samples were not weighed on a regular
basis but no sample recovery issues were
encountered during the drilling program.
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.
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 RC and diamond core samples are
geologically logged. Core samples are
also orientated and logged for geotechnical
information.
Whether logging is qualitative or quantitative in nature. Core
(or costean, channel, etc) photography.
The total length and percentage of the relevant intersections
logged.
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.
RC drill holes are sampled at 1m intervals
and split using a cone splitter attached to
the cyclone to generate a split of ~3kg.
Diamond core was quartered with a
diamond saw and generally sampled at 1m
intervals with shorter samples at geological
contacts.
Logging
Sub‐sampling
techniques and
sample
preparation
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.
RC sample splits (~3kg) are pulverized to
85% passing 75 microns.
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.
Diamond core samples are crushed to 70%
passing 6mm and then pulverized to 85%
passing 75 microns.
Whether sample sizes are appropriate to the grain size of the
material being sampled.
Sampling techniques used by KGL are
appropriate and generate sub-samples for
analysis that are representative of the
whole sample.

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.
The QAQC data includes standards,
duplicates and laboratory checks. In ore
zones Standards are added at a ratio of
1:10 and duplicates and blanks 1:20.
Basemetal samples are assayed using a
four acid digest with an ICP AES finish.
Gold samples are assayed by Aqua Regia
with an ICP MS finish. Samples over
1ppm Au are re-assayed by Fire Assay
with an AAS finish.
An umpire laboratory is used to check ~1%
of samples analysed.
Assay methods are appropriate for the
style of mineralisation and provide results
of acceptable accuracy.
Verification of
sampling and
assaying
Location of data
points
Data spacing and
distribution
Orientation of data
in relation to
geological
structure
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.
The verification of significant intersections by either
independent or alternative company personnel.
Data is validated on entry into the
Datashed database.
The use of twinned holes.
Further validation is conducted when data
is imported into Vulcan.
Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic) protocols.
Discuss any adjustment to assay data.
Below detection limit results are replaced
in the database with values of half the
detection limit.
Selected holes are twinned.
Intersections in selected historic holes
were visually validated.
Surface collar surveys were picked up
using a Trimble DGPS.
Downhole surveys were taken during
drilling with a Ranger or Reflex survey tool
every 30m with checks conducted with a
Gyrosmart gyro and Azimuth Aligner.
All drilling is conducted on the MGA 94
Zone 53 grid. All downhole magnetic
surveys were converted to MGA 94 grid.
A digital terrain model was generated using
grid based DGPS data and surveyed
drillhole collar data.
Drilling for Inferred resources has been
conducted at a spacing of 50m along strike
and 80m within the plane of the
mineralized zone. Closer spaced drilling
was used for Indicated resources.
Shallow oxide RC drilling was conducted
on 80m spaced traverses with holes 10m
apart.
4m RC composite samples were used in
unmineralised portions of the hangingwall
and footwall.
Holes were drilled perpendicular to the
strike of the mineralization a default angle
of -60 degrees but holes vary from -45 to 80.
There is no sampling bias based on drill
hole orientation.
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.
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.
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.
Sample security
The measures taken to ensure sample security.
Samples were stored in sealed polyweave
bags on site and transported to the
laboratory at regular intervals by KGL staff.
Audits or reviews
The results of any audits or reviews of sampling techniques
and data.
The sampling techniques are regularly
reviewed.

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.
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.
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.
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.
