<font style="font-family: Arial; font-size: 13px">Diamond drill
holes are the principal source of geological and grade information
for the Golpu deposit. Diamond core drilling was used to obtain
continuous samples ranging in size from PQ3 to NQ3 with rare
intervals of BQ which were cut into half (in the case of HQ, NQ and
BQ) and into half or quarter (in the case of PQ) using a diamond
core saw, from which half or quarter is prepared for assay and the
remaining core retained in the core farm as reference.</font></div>

<font style="font-family: Arial; font-size: 13px">The half or
quarter core sent for assay was bagged in labelled calico sample
bags with the sample number scribed on an aluminium strip included
in the bag. The calico bags were placed in larger polyweave bags
and transported by road or helicopter to Lae by company employees.
Sampling intervals are typically 1m or 2m fixed intervals. The
entire half or quarter core is dispatched for sample preparation.
Core recovery is recorded to ensure a representative sample is
obtained.</font></div>
<div style="text-align: justify; margin-left: 0px; margin-right: 0px; text-indent: 0px">
<font style="font-family: Arial; font-size: 13px">All core was
logged and photographed prior to cutting. Some core was wrapped in
tape during sampling to maintain core quality. Oriented core is cut
along the orientation line at the bottom of hole to reduce the
possibility of sample bias. Sample numbers and drill hole intervals
were recorded by the responsible geologist and used by technicians
for cutting and sampling. A sample despatch sheet documenting the
sample numbers and required assay work was sent with each sample
batch to the laboratory.</font></div>

<font style="font-family: Arial; font-size: 13px">All drill core is
sampled and assayed over the entire hole length. However empirical
rock strength data is required for geotechnical input to mine
designs - since 2011 approximately 20cm of whole core was taken at
50m intervals from all holes for Unconfined Compressive Strength
testing which were not assayed. This is not considered to present a
material impact on sample quality due to the disseminated,
stockwork and micro-fracture infill nature of the
mineralisation.</font></div>

<font style="font-family: Arial; font-size: 13px">The Golpu deposit
lies in a block of deformed Upper Mesozoic to Middle Miocene
metasedimentary to sedimentary rocks cut by Miocene-Pliocene
calc-alkaline dioritic intrusives. Copper and gold mineralisation
results from a multiple intrusive porphyry system with the upper
portion overprinted by high sulphidation epithermal alteration.
Post mineral faulting has displaced and rotated the original

<font style="font-family: Arial; font-size: 13px">The deformational
history of PNG is characterised by accretion during oblique
collision of the Australian and Pacific plates. A series of
arc-normal transfer structures formed across PNG which taped mantle
derived melts to high crustal levels. One of these structures
termed the Wafi Transfer Structure is interpreted to have
facilitated the emplacement of the Golpu intrusives.</font></div>

<font style="font-family: Arial; font-size: 13px">The Golpu
Porphyry system consists of multiple, hornblende-bearing diorite
porphyries intruded into host sediments. The porphyries are
separated based on their spatial position, and where not texturally
destroyed, into coarse hornblende-rich, feldspathic-rich or quartz
&#x2018;eye&#x2019; inclusions variants. Intrusives range from small
dykes to small stocks and apopheses. Individual intrusions pinch
and swell vertically over tens of metres and form stocks, pipes and
dykes.</font></div>
<div style="text-align: justify; margin-left: 0px; margin-right: 0px; text-indent: 0px">
<font style="font-family: Arial; font-size: 13px">The Golpu deposit
is approximately 800m by 400m elliptical in plan and extends from
200m below surface to approximately 2,000m. Hydrothermal alteration
related to the porphyry gol-copper mineralisation forms a
predictable zonal arrangement grading from potassic core to
propylitic margins. A high-sulphidation epithermal system is
&#x2018;telescoped&#x2019; over the upper portion of the porphyry
system forming a central alunite&#x2013;quartz (advanced argillic)
core grading out to dickite&#x2013;kaolinite (argillic) with an
outer margin of sericite alteration. This results in either
epithermal-dominant, interaction (mixed) or porphyry-only zones
within the Golpu deposit.</font></div>
<div style="text-align: justify; margin-left: 0px; margin-right: 0px; text-indent: 0px">
<font style="font-family: Arial; font-size: 13px">Mineralisation is
derived from either the porphyry or epithermal systems. Within the
porphyry environment, mineralisation is disseminated, microfracture
and stockwork vein controlled. The dominant copper-gold sulphide
species varies laterally and vertically within the deposit from an
inner bornite (plus chalcopyrite) core, chalcopyrite as the
dominant copper sulphide grading to a pyrite only shell. The
porphyry system is mineralised with gold, copper, silver and
molybdenum. The Livana Porphyry is the main mineralised porphyry.
Other porphyries act either as weak mineralisers or as benign
hosts.</font></div>
<div style="text-align: justify; margin-left: 0px; margin-right: 0px; text-indent: 0px">
<font style="font-family: Arial; font-size: 13px">In the high
sulphidation epithermal system which is &#x2018;telescoped&#x2019;
over the upper portion of the Golpu Porphyry, gold occurs within
pyrite or as electrum associated with pyrite-enargite-tetrahedrite.
Abundant arsenian pyrite results in high sulphur and elevated
arsenic levels in the epithermal altered volume. Mineralisation
broadly follows the metasedimentary and volcanic host rocks
stratigraphy (40&#xB0; dip to east).</font></div>

epithermal systems with offsets of up to 200m within the
mineralised column and rotated the high grade porphyry core between
faults to dip 70 degrees to grid west.</font></div>

Resource grades were estimated with Ordinary Kriging using pairwise
variograms of 10m composites for seven elements: gold, copper,
silver, molybdenum, sulphur, arsenic, and iron with Vulcan software
using domain specific variograms and search for informing 10m
composites using the variogram anisotropy. The grades were
estimated into a block model with 40m x 40m x 40m parent cells with
10m x 10m x 10m resolution on domain margins. This reflects the
estimation precision available from the drillhole spacing of less
than 100m x 100m in the upper portion of the deposit and up to 200m
x 200m in the lower portions of the deposit and the planned mining
method (block caving). Variograms are typically low nugget (7-17%
for gold and 5-30% for copper) with long ranges. Search parameters
vary by element and estimation domain but reflect the orientation
and ranges of the variograms. The maximum number of samples per
block typically restricts the actual distance of informing samples
to substantially less than the search limits. While there are
spatial associations between elements, all are estimated
independently.</font></div>

<font style="font-family: Arial; font-size: 13px">The grade

mineralisation margin to the porphyry core in a relatively
continuous relationship. Domain drift is apparent for the porphyry
system and pairwise variograms were used for modelling grade
continuity. Contact analyses indicated the Hornblende (Livana)
Porphyry has abrupt grade contacts and is modelled independently.
Estimation domains are also bounded at all major thrust faults
where drilling has demonstrated clear grade truncations. Most other
estimation domains are continuous &#x2018;diffusive&#x2019;
transitions from mineralised porphyry margins to the mineralisation
limit regardless of host lithology. All porphyry-related domains
are modelled with an orientation defined by the elongation of the

Estimation of the Golpu Ore Reserve involved standard steps of mine
optimisation, mine design, production scheduling and financial
modelling. Factors and assumptions have been based on numerical
modelling as well as experience and performance in similar caving
operations. The basis of the analysis is considered at Feasibility
(BC44 and BC42) and Pre-Feasibility (BC40) study levels.Preceding
Pre-Feasibility and Feasibility studies completed in 2012, 2014 and
2015 deemed block caving to be the appropriate underground mining
method to maximise the economic output of the Mineral Resource. The
Feasibility Study Update (on which this Ore Reserve statement is
based) defined a three lift block cave mine plan. Extraction levels
for the three block caves are; 4400mRL (BC44), 4200mRL (BC42), and
the 4000mRL (BC40). Geotechnical assessment during the studies has
resulted in the following key block cave mine design parameters in
the Feasibility Study Update:Mine Design ParameterValueUndercutting

collect further data for further geological, geotechnical and
metallurgical studies to inform final design.Grade control during
the production phase will be in the form of block cave drawpoint
sampling.The in situ grade model estimated in July 2014 was the
basis for the Ore Reserve estimate.The Feasibility Study Update
proposes the following mining approach:&#x25CF;Secondary/Initial
underground access via the Nambonga Decline to provide earlier and
quicker access to underground drill platforms, second means of
egress and ventilation.&#x25CF;Primary underground access via the
Watut Portal and the twin Watut Declines to the underground block
cave mine. The Watut Declines also form part of the primary
ventilation circuit and materials handling system conveying ore to
the Watut Process Plant.&#x25CF;A &#x2018;Cave Engineering
Level&#x2019; established above the Reid Fault at 4870mRL for data
gathering, further refinement of the rock mass, monitoring of the
cave and potentially dewatering.&#x25CF;Ore extracted via three
block caves producing at 17Mtpa (design capacity) using an inclined
conveying system to discharge on a stockpile on the surface.The
following Modifying Factors have been applied:&#x25CF;All
development has mining factors for dilution and recovery applied to
accurately represent the expected mined tonnes.&#x25CF;Decline,
access and infrastructure shapes for BC42 and BC40 outside of the
Mineral Resource have tonnes contributing but not metal; these
tonnes are allocated to unclassified material.&#x25CF;PCBC&#x2122;
software is used for cave production scheduling and estimation of
grade for material drawn from the block caves.The total Life of
Mine dilution is approximately 17%.The geological model is
classified as Indicated and Inferred Mineral Resources. There is no
Measured Mineral Resource. Mine plans are based on the extraction
of caving blocks solely delineated on the basis of Indicated
Mineral Resources.Ore Reserves estimates and statements are
required to include estimates of dilution. The dilution included in
the total Ore Reserve (400Mt on 100% basis) is approximately 79Mt
due to the block cave mining method. The dilution included in the
Ore Reserve contains 7% of the gold metal and 5% of the copper
metal of the Ore Reserve and does not have a material impact upon
the estimate. Even without consideration of the metal contained in
the dilution incorporated in the Ore Reserve, the economic analysis
indicates an economic Probable Ore Reserve.The Wafi-Golpu Project
is a greenfield block caving project and will require the following
mining infrastructure to support the block caves:&#x25CF;ventilation
fans and refrigeration equipment;&#x25CF;dewatering
equipment;&#x25CF;crushing and conveying equipment;
and&#x25CF;underground workshop, service and personnel
facilities.</div>
