1 Important Information

This is a supplementary prospectus ( Second Supplementary Prospectus ) intended to be read with the prospectus dated 9 November 2016 ( Prospectus ) and supplementary prospectus dated 18 November 2016 ( First Supplementary Prospectus ) issued by Ardea Resources Limited ( Ardea or the Company ) and Heron Resources Limited ( Heron ).

This second Supplementary Prospectus ( Second Supplementary Prospectus ) is dated 6 January 2017 and was lodged with the Australian Securities and Investments Commission ( ASIC ) on that day. ASIC, ASX Limited ( ASX ) and their respective officers do not take any responsibility as to the contents of this Second Supplementary Prospectus.

Other than as set out below, all details in relation to the Prospectus remain unchanged. To the extent of any inconsistency between this Second Supplementary Prospectus, the Prospectus and the First Supplementary Prospectus, this Second Supplementary Prospectus will prevail. Unless otherwise indicated, terms defined and used in the Prospectus have the same meaning in this Second Supplementary Prospectus.

This Second Supplementary Prospectus will be issued with the Prospectus and the First Supplementary Prospectus as an electronic prospectus and may be accessed on the Company’s website at www.ardearesources.com.au.

This is an important document and should be read in its entirety. If you do not understand this document, you should consult your professional advisors without delay.

2 Corporate and Project Updates

As previously announced to ASX:

  • 2.1 Extension of Closing Date to 20 January 2017

The extension allows:

  • Ardea an opportunity to raise further funds in excess of the minimum amount; and

  • the retention of OnMarket Bookbuilds to assist with maximising funds raised under the capital raising, particularly geared to their clients seeking cobalt exposure.

Details regarding the extension of Closing Date are outlined in Heron’s ASX announcement dated 23 December 2016 which forms Schedule 1 to this Second Supplementary Prospectus.

2.2 KNP Cobalt Zone – Premier Cobalt Resource in Australia, 49.7Mt at 0.11% cobalt and 0.9% nickel

Ardea has completed an independent Resource Statement for the cobalt-rich portions of the Kalgoorlie Nickel Project ( KNP ).

The KNP Cobalt Zone is a key element of Ardea’s IPO and listing on ASX:

  • The KNP Cobalt Zone with 49.7Mt at 0.12% cobalt and 0.86% nickel is a significant world resource of “ethical cobalt” (in contrast to a portion of world supply sourced from the Democratic Republic of the Congo);

8019532_263.doc v10

  • The full KNP with 805Mt at 0.05% cobalt and 0.7% nickel[1] (refer Prospectus pages 84-87 and the First Supplementary Prospectus) is by far the largest cobalt resource documented for an ASXlisted Australian mineral explorer; and

  • allows Ardea the opportunity to focus on a Pre-Feasibility Study on the high grade KNP Cobalt Zones and aligning the Company to the high-tech lithium ion battery sector.

Details regarding the Kalgoorlie Nickel Project - Cobalt Zone are outlined in Heron’s ASX announcement dated 6 January 2017 which forms Schedule 2 to this Second Supplementary Prospectus.

2.3 Project Update – KNP Cobalt Zone and Lewis Ponds Bulk Tonnage Exploration Target

Based on recent field work and financial modelling subsequent to lodging the Ardea Prospectus, Ardea has completed new resource interpretations and forward programs for its key projects:

  • The full KNP with 805Mt at 0.05% cobalt and 0.7% nickel (refer Prospectus pages 84-87 and the First Supplementary Prospectus) is the largest cobalt resource documented in Australia, and in addition;

  • The KNP Cobalt Zone with 49.7Mt at 0.11% cobalt and 0.9% nickel is a significant world resource of “ethical cobalt”; and

  • Occurrences of the semi-precious gemstone chrysoprase within the KNP have for the first time been systematically evaluated as a bulk mining operation.

  • At the Lewis Ponds project a bulk tonnage Exploration Target was defined;

  • Significant base metal-gold open-pit potential, with orogenic gold and base metal mineralisation defined which is very similar to other bulk tonnage deposits in the region (refer Prospectus pages 9-10, 43-48, 83 and the First Supplementary Prospectus); and

  • The Lewis Ponds Main Zone and Tom’s Zone main shaft mullock have been sampled by Ardea and returned assays of 9.9–12.1g/t gold and 272–539g/t silver.

  • New tenement applications complementing existing Ardea projects

  • Lewis Ponds, NSW – several EL applications secured and already recommended for grant; and

  • Bedonia West and Perrinvale, WA – high quality Ni-Cu-PGM targets acquired.

Details regarding the Project Update are outlined in Heron’s ASX announcement dated 6 January 2017 which forms Schedule 3 to this Second Supplementary Prospectus.

Heron Resources Limited

ASX/TSX Release

6 January 2017

Ardea Resources Limited

KNP Cobalt Zone – Australia’s Premier Cobalt Resource

Heron Resources Limited ( Heron or Company ) is pleased to advise that its wholly owned subsidiary, Ardea Resources Limited ( Ardea ), has completed an independent Resource Statement for the cobalt-rich portions of the Kalgoorlie Nickel Project ( KNP ). The KNP Cobalt Zone is a key element of Ardea’s IPO and listing on ASX, planned for February 2017.

The new estimate for the KNP Cobalt Zone is 49.7Mt at 0.12% cobalt and 0.86% nickel , occurring within three separate KNP centres (Table 1). The global cobalt resource for the full KNP remains unchanged at 805Mt at 0.05% cobalt and 0.7% nickel using a 0.5% Ni cut-off grade[1] .

Ardea completed a review of the KNP in late 2016, concluding that the KNP as a whole comprises Australia’s and the developed world’s largest cobalt resource[2] .

The KNP Cobalt Zone is located 50-150km north and northeast of Kalgoorlie in Western Australia (Figures 1 & 2), a favoured investment jurisdiction with excellent infrastructure that can facilitate ethical cobalt production for green energy.

Independent firm Ridley Mineral Resource Consulting Pty Limited ( RMRC ) has reported the following Mineral Resources within the five cobalt-rich prospect areas based on identified zones of continuous elevated cobalt mineralisation using a 0.08 % Co cut-off in these areas:

Heron Resources Limited ASX/TSX Release

==> picture [55 x 88] intentionally omitted <==

Vale Inco[3] completed a $34.5 million Pre-Feasibility Study (PFS) on the KNP in 2009 concluding that it is “ one of the most prospective nickel laterite tenement packages in the world ” and “ the KNP tenements form one of the largest potential nickel laterite deposits in the world ”.

RMRC has prepared the 2017 updated Resource Statement using modified reporting criteria for cobalt abundances in existing resource models that were previously prepared by Snowden Mining Industry Consultants (Snowden) and Heron.

This update describes the current publicly reported Mineral Resources for five prospect areas within the KNP known to contain cobalt-rich mineralisation. Two of the estimates, completed by Snowden in 2004, formed part of Heron’s early assessment of the Scotia Dam and Black Range prospect areas.

Estimates for the Goongarrie South and Big Four prospects were completed by Heron in 2009 as part of a KNP PFS update following an initial PFS completed by Vale Inco in 2009. The current estimate for Aubils was by Heron in 2008 as part of feasibility assessment of the Yerilla Nickel Project.

The KNP Cobalt Zone is associated with a distinctive geo-metallurgical type defined as “Clay Upper Pyrolusitic”. Mineralogy is goethite, gibbsite and cobaltian pyrolusite (strictly “asbolite” or “cobaltian wad”). Each of the cobalt-rich zones typically occurs as a sub-horizontal body (Figure 4) at a palaeo-water table within the KNP (and developed as a late stage supergene enrichment). This material is particularly well developed at Goongarrie South, which will be the focus area for Ardea’s cobalt development studies.

Heron Resources Limited ASX/TSX Release

Based on the contained cobalt metal within the deposit, the KNP is Australia’s largest cobalt deposit (Table 2, Figure 3). By this measure, it is more than three times larger than Australia’s second largest cobalt deposit. The newly-defined cobalt resource from the high-grade KNP Cobalt Zone is a subset within the larger KNP resource, and the subset by itself is Australia’s fourth largest cobalt resource. The KNP Cobalt Zone also is amongst the highest cobalt grades in Australia (Tables 2 & 3). In terms of global cobalt resources, the KNP is the premier resource within stable western jurisdictions.

The updated resource reporting for cobalt-rich zones provides a basis for KNP remodelling work planned by Ardea that is focused on cobalt grade shells. Quantifying the cobalt-rich mineralisation at the KNP marks the first part of a refocussing for the KNP onto the cobalt component of the deposit.

Forthcoming drilling and metallurgical studies will move the KNP towards a PFS focussing on cobalt-nickel-manganese feedstocks for the lithium ion battery industry (Lithium Nickel Manganese Cobalt Oxide - LiNiMnCoO2 or NMC).

Memorandum

Recipient Ian Buchhorn Recipient company Ardea Resources Limited Memo date 5/01/2017 Author James Ridley Director and Principal Geologist – Ridley Mineral Resource Consulting Pty Ltd Memo Subject Updated Mineral Resource Reporting for Regions of Continuous Cobalt Rich Mineralisation in the Kalgoorlie Nickel Project

Introduction

Ridley Mineral Resource Consulting Pty Ltd (RMRC) has been retained by Ardea Resources Limited (Ardea) to undertake updated Mineral Resource reporting for five prospect areas containing continuous cobalt rich nickel laterite mineralisation in Ardea’s Kalgoorlie Nickel Project (KNP) located from 65km to 170km north of Kalgoorlie in Western Australia. The five cobalt rich prospect areas include, Goongarrie South, Big Four, Scotia, Black Range and Aubils which are highlighted in blue in the project location plan displayed in Figure 1.

James Ridley (Ridley), a Director, Principal Geologist and full time employee with RMRC was previously employed as a Senior Resource Geologist with Heron Resources Limited (Heron) from 2004 to 2011 when Heron owned the KNP and has detailed knowledge of the geology, mineralisation, exploration procedures and data, and current resource models for the KNP. Ridley prepared the resource models used by Ardea and Heron for current Mineral Resource Estimate (MRE) reporting for the Goongarrie South (GS), Big Four (BF) and Aubils (AU) prospect areas and is also familiar with the resource models prepared by Snowden Mining Industry Consultants Pty Ltd (Snowden) on behalf of Heron in 2004 which inform current MRE reporting for the Scotia (SC) and Black Range (BR) prospect areas. Ridley has visited all five prospect areas whilst employed by Heron.

Neither RMRC nor Ridley has any vested interest in Heron or their upcoming spinoff Ardea.

KNP Mineralisation Summary

The nickel laterite mineralisation within the KNP areas is developed from the weathering and near surface enrichment of Achaean-aged olivine-cumulate ultramafic units. The mineralisation is usually within 60 metres of surface and can be further sub divided on mineralogical and metallurgical characteristics into upper iron-rich material and lower magnesium-rich material based on the ratios of iron to magnesium. The deposits are analogous to many weathered ultramafic-hosted nickel-cobalt deposits both within Australia and world-wide.

Cobalt rich mineralisation is typically best developed in iron rich material in regions of deep weathering in close proximity to major shear zones or transfer shear structures and to a lesser extent as thin zones along the interface of ferruginous and saprolite boundaries at shallower depths proximal to shear structures.

Resource Models

The updated MRE reporting is based on resource estimates for the GS, BF, and AU prospects completed in 2008 and 2009 by Heron (Ridley), and estimates for the SC and BR prospects completed by Snowden Mining Industry Consultants Pty Ltd (Snowden) on behalf of Heron in 2004. These resource estimates remain a contributing source to Heron’s ongoing Annual Mineral Resource Reporting for the greater KNP through FY 2016, albeit with additional constraints applied and updated reporting documentation produced by Heron in FY13 aligned with updated reporting requirements complying with the implementation of JORC Code 2012. No further drilling or resource modelling work has been undertaken for the KNP subsequent to the resource modelling noted above.

The following resource models (Vulcan software format) were used to inform the updated Mineral Resource reporting for the five cobalt rich prospect areas:

  • Goongarrie South (Heron-2009): gsrbm_ikok_trim.bmf

  • Big Four (Heron-2009): b4rbm_ikok_trim.bmf

  • Aubils (Heron-2008): aubresmod_0608trim.bmf

  • Scotia (Snowden-2004): scotia.bmf

  • Black Range (Snowden-2004): siberia.bmf

A copy of each model was produced with a ‘_201612’ suffix added to each file name, in which an additional block model variable was added, ‘co_res_201612’ in which coding relating to cobalt rich mineralisation constraints was assigned.

Resource Modelling

The original resource modelling studies for the five prospect areas considered in this study included the following investigations:

  • Review of regional and local geology;

  • Review of exploration drilling, survey (topography and collars), geological logging, sampling and geochemical and bulk density analytical methods and procedures;

  • Drillhole database review and validation;

  • Assessment of available routine laboratory and external QAQC data and verification sampling data (twinning of RC holes with diamond and sonic drillholes);

  • Interpretation and 3-D wireframe modelling of base overburden, base of ‘ClayUpper’ (ferruginous zone) and base of ‘Clay Lower’ (saprolite zone). The boundary between ferruginous and saprolite domains for Goongarrie South and Big Four was determined by indicator kriging where the weathering profile is more complicated and ferruginous material can underlie saprolite material as the result of paleo-water table fluctuations;

  • Interpretation and wireframe modelling of mineralisation envelopes using a nominal 0.25% Ni lower cutoff for the Goongarrie South and Big Four prospects, a 0.4% Ni cutoff for Aubils and a

Heron Resources Limited – KNP Project

0.5% Ni cutoff for the Scotia and Black Range prospects. Lower grade intersections were also included where necessary in order to maintain 3-D geological continuity of the envelopes.

  • Detailed statistical analysis of Ni, Co, MgO, FeO, Al2O3, CaO, SiO2, Mn, and Cr data for 2 metre composites of the drill sample assay data subdivided by the Ni laterite focused modelling domains (ferruginous and saprolite). CaO, SiO2, Mn and Cr data were not available for the Scotia and Black Range prospects;

  • Statistical analysis of relationships between XRD determined mineralogy and multi-element geochemistry for samples from the Jump-Up Dam (JUD) prospect located in the Yerilla subproject area of the KNP. The resulting geochemical material type classification scheme was subsequently applied to the AU, GS and BF resource models after cross validation against drill sample regolith logging data;

  • Statistical analysis of the available bulk density data for the GS and JUD prospects subdivided by the JUD geochemical material type classification scheme. Mean bulk density values determined for GS were applied to the BF prospect and the results for JUD were signed to the AU prospect based on the similar host ultramafic lithologies and mineralisation styles between the paired prospect areas. Estimated average bulk density values were assigned to the earlier resource models for the Scotia and Black Range prospect areas;

  • Detailed variography for all grade attributes estimated in each prospect area;

  • Resource block models constructed using parent block sizes with dimensions typically half the average drill hole spacing in the mineralised regions of each prospect area. However, block dimensions for BR are not optimal, having been chosen to best represent the drill spacing(s) in the Siberia North and South prospect areas which were incorporated into the same resource model as the BR prospect.

  • Ordinary kriging grade estimation mostly based on 2m drillhole composites of all grade attributes with available assay data for each prospect area.

  • Original Mineral Resource classification and reporting based on drill hole spacing, nickel grade continuity and/or estimation quality criteria based on assessments of kriging efficiency results.

  • Updated Mineral Resource classification based on the original classification and additional constraints based on a pit optimisation work completed by Heron in 2013 for reporting which excluded previously reported resources located outside pit shells produced using optimistic mining, processing and development capital cost criteria.

Assessment of Cobalt Rich Mineralisation

Assessment of the cobalt rich mineralisation in each prospect area has been undertaken using the following approach:

  • Generate wireframe grade shells based on the resource block model cobalt grade estimates using a 0.08% Co cutoff grade.

  • Visually check the grade shells against the block model grade estimates in plan, section and 3-D.

  • Identify grade shell regions containing continuous cobalt rich mineralisation informed by multiple drill hole intersections.

Heron Resources Limited – KNP Project

Ridley Mineral Resource Consulting

  • Use wireframe boolean operations to remove grade shell regions that are poorly informed with drilling or demonstrate poor 3-D continuity. No trimming of the grade shells for the Black Range prospect was conducted as drill spacing was considered too broad (400mE by 100mN) to adequately demonstrate robust zones of higher grade cobalt mineralisation that are more selective than currently Mineral Resource reporting constraints using a 0.5% Ni cutoff.

  • Generate wireframe grade shells based on the block model nickel grade estimates using 0.5% Ni and 0.7% Ni cutoff grades and review the relative location and extents of the trimmed cobalt rich grade shells against the two sets of nickel grade shells. These grade shell comparisons clearly demonstrate that most of the cobalt rich mineralisation is associated with higher grade nickel mineralisation.

Plan views of the raw and trimmed cobalt grade shells and drill hole collars for each prospect area are displayed in Figures 2 though 9, while similar views comparing the trimmed cobalt rich grade shells with the nickel grade shells are displayed in Figures 10 through 18.

Updated Resource Reporting for Cobalt Rich Zones

The trimmed block model grade shells based on a 0.08% Co cutoff were used to constrain flagging of the resource block model for each prospect area; co_res_201612 = 1. The block model flagging was then used to constrain the updated Mineral Resource reporting for the cobalt rich mineralisation with no cutoff grade criteria applied. The same resource classification currently used by Ardea and Heron for Mineral Resource reporting for the greater KNP remains unchanged as the informing resource models and grade attributes of economic interest (nickel and cobalt) for the updated reporting remain unchanged.

The Mineral Resource estimates for the KNP have been classified in accordance with the guidelines as set out in the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (JORC, 2012 Edition). The classification has taken into consideration the quality of the exploration data, geological understanding, grade continuity and drill hole spacing. RMRC has checked the current resource classification criteria and corresponding block model coding for each of the five prospect areas informing the updated resource reporting and determined them to be valid.

The Mineral Resources relating regions of continuous cobalt rich mineralisation identified in this study are summarised in Table 1. These resources predominantly form a subset of the Mineral Resources reported by Heron for the greater KNP and do not supersede nor materially add to the current resources reported by Heron for the greater KNP. The current Mineral Resources reported by Heron using a 0.5% Ni cutoff for the five prospect areas containing cobalt rich resources are summarised in Table 2.

represents the
combined methods
for all Heron (HRR)
Nickel Laterite
Resources. Where
data not collected
by HRR has been
used in the
resource
calculations,
variances in
techniques are
noted.
• 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.
• The nickel laterite resources were sampled by drilling using dominantly Reverse Circulation
(RC) with occasional Diamond Drill (DD) on various grid spacing between 10x10 metre and
80x160 metre spacing. Holes were usually vertical (-90 degree dip), designed to optimally
intersect the sub-horizontal mineralisation. The majority of holes were sampled on 2 metre, or
less commonly 1 metre down hole intervals.
• RC holes form the majority of the samples used in the resource calculation.
• DD holes were drilled for a combination of:

twin testing of RC drilling;

density determination;

geotechnical logging and test work;

geological logging (structural logging); and

metallurgical test work.
Where appropriate the results of diamond core sampling and assays were used in the
resource estimate.
• A number of bulk sample holes employing either Calweld (900 to 1200mm, large diameter well
boring rig) or Sonic drilling techniques were also completed at Jump Up Dam, Goongarrie,
Highway and Siberia Deposits. These holes were primarily for obtaining bulk samples for
metallurgical studies and the assay results were not used in the resource calculation.
• Bulong East resources were calculated using the database of Bulong Mining Pty Ltd (in
Receivership). Techniques employed were broadly similar to those used by Heron.
• Goongarrie Hill, Goongarrie South, Highway and Siberia Deposits were all partially explored by
Vale between 2002 and 2007. Vale/ Inco employed the same drilling and sampling techniques
as Heron for these deposits.
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 performed with a face sampling hammer (bit diameter between 41/2and 51/4
inches) and samples were collected by either a cone (majority) or riffle splitter using 2 metre
composites. Sample condition, sample recovery and sample size were recorded for all drill
samples collected by HRR.
• DD holes were drilled with HQ triple tube. All material of sufficient competence was oriented
using spear or Easymark™ techniques. All diamond holes were logged for geotechnical,
geological and density. Where appropriate (holes not drilled for metallurgical purposes), holes
were whole core sampled to geological boundaries (approximately 1 metre) and assayed.

Ridley Mineral Resource Consulting

Criteria JORC Code explanation Commentary
Drilling techniques
(continued)
• Calweld samples (not used in resource model but used for metallurgical testing) were collected
in bulka bags on 1 metre down hole intervals.
• Sonic drill samples were collected as whole core samples, 6 inches diameter of up to 1 metre
lengths in sealed clear plastic wrap. Sonic core of longer lengths was split as it was retrieved
from the drill string to facilitate handling of the heavy samples.
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 chip sample recovery was recorded by visual estimation of the reject sample, expressed
as a percentage recovery. Overall estimated recovery was approximately 80%, which is
considered to be acceptable for nickel laterite deposits. RC Chip sample condition recorded
using a three code system, D=Dry, M=Moist, W=Wet. DD Core recovery was recorded
during logging. A small proportion of samples were moist or wet (11.5%), with the majority
of these being associated with soft goethite clays, where water injection has been used to
improve drill recovery.
• Measures taken to ensure maximum RC sample recoveries included maintaining a clean
cyclone and drilling equipment, using water injection at times of reduced air circulation, as well
as regular communication with the drillers and slowing drill advance rates when variableto
poorground conditions are encountered.
• For diamond drilling, drill runs were reduced to as little as 0.5 metre in poor ground conditions
to maximise core recovery. Core recovery was excellent being over 90% for all deposits.
• Recovery from Sonic drilling was excellent with very good recoveries experienced in soft
goethite clays where water injection was required in RC to facilitate acceptable recoveries.
• In Calweld drilling, drill bit diameter was changed to account for ground hardness to maximise
sample recovery and bore hole penetration. A specialized shoot was constructed to maximise
the recovery from the drill head. Samples were stored in bulka bags to prevent contamination
or sample loss.
• A number of twin holes using both DD and RC methods were drilled to confirm that theRC
sampling was repeatable and therefore representative and without significant bias. These twin
holes included areas where wet ground conditions were experienced during RC drilling. No
statistically significant bias was recorded in the results.
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.
• For RC drilling, visual geological logging was completed for all RC drilling on 1 metreintervals.
The logging system was developed by Heron specifically for the KNP and was designed to
facilitate future geo-metallurgical studies. Logging was performed at the time of drilling, and
planned drill hole target lengths adjusted by the geologist during drilling. The geologist also
oversaw all sampling and drilling practices. A mixture of Heron employees and contract
geologists supervised all drilling. A small selection of representative chips were also collected
for every 1 metre interval and stored in chip-trays for future reference. Only drilling contractors
withprevious nickel laterite experience and suitable rigs were used.

Logging
(continued)
• For DD holes, both visual geological and geotechnical logging were performed on all drillcore.
Core was also selectively sampled for both geological and metallurgical test work.
• Calweld and Sonic holes were visually geologically logged prior to being sampled for
metallurgical test work.
• The geological legend used by Heron is a qualitative legend designed to capture the key
physical and metallurgical features of the nickel laterite mineralisation. Logging captured the
colour, regolith unit and mineralisation style, often accompanied by the logging of protolith,
estimated percentage of free silica, texture, grain size and alteration. Logging correlated well
with the geochemical algorithm developed by Heron for the Yerilla Nickel Project for material
type prediction from multi-element assay data.
• Drilling conducted by Vale / Inco at Highway, Goongarrie and Siberia was logged in similar
detail to Heron’s procedures, but used a slightly modified geological legend. There is a direct
translation between the Vale /Inco and Heron logging legends.
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 of samples.
• 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.
• Whether sample sizes are appropriate to the grain size of the material
being sampled.
• RC Drilling; 2 metre (and rarely 1 metre) composite samples were recovered using a 15:1 rig
mounted cone splitter or trailer mounted riffle splitter during drilling into a calico sample bag.
Sample target weight was between 2 and 3kg. In the case of wet clay samples, grab samples
taken from sample return pile, initially into a calico sample bag. Wet samples stored
separately from other samples in plastic bags and riffle split once dry.
• For RC sampling QAQC was employed on all programs. A standard, blank or duplicate
sample was inserted into the sample stream 10 metres on a rotating basis. Standards were
either quantified industry standards, or standards made from homogenised bulk samples of the
mineralisation being drilled (in the case of the Yerilla project). Every 30thsample a duplicate
sample was taken using the same sample sub sample technique as the original sub sample.
Sample sizes are appropriate for the nature of mineralization. QAQC results were verified
against each program prior to loading into the database.
• A small percentage of holes were separately resampled post drilling to confirm the integrity of
the different sampling techniques employed.
• For DD holes, where not required for metallurgical or geotechnical purposes, samples were
taken using whole core, and submitted for assay. No duplicates of core samples were taken,
but standards and blanks were employed as for the RC drilling. Whole core sampling was
used to increase the sample size to approximate the same sample mass as for the RC drilling
for the purposes of comparing of twinned holes, and to eliminate difficulties in biasing of
samples during the splitting of core, with its inherent variable hardness.

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 (eg standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels
of accuracy (ie lack of bias) and precision have been established.
• All Heron and Vale / Inco samples were prepared and analysed by Ultratrace Laboratories in
Perth by silicate fusion / XRF analysis (lab method XRF202) for multiple grade attributes (Ni,
Co, MgO, FeO, Al2O3, SiO2, CaO, Mn, Cr, Cu, Zn, As, S and Cl). Fusion / XRF analysis is
an industry standard method used to analyse nickel laterite ores and Ultratrace is a
reputable commercial laboratory with extensive experience in assaying nickel laterite
samples from numerous Western Australian nickel laterite deposits.
• Ultratrace routinely inserts analytical blanks, standards and duplicates into the client sample
batches for laboratory QAQC performance monitoring.
• Heron also inserted QAQC samples into the sample stream at a 1 in 10 frequency, alternating
between duplicates splits, blanks (quartz or garnet sands) and standard reference materials.
• All of the QAQC data has been statistically assessed and the precision and accuracy of the
assay data for the important grade components has been found to be acceptable and suitable
for use in resource estimation.
• A small number of historic samples at Bulong, Goongarrie and Highway were assayed by KAL
Laboratory in Kalgoorlie using four acid digestion (4AD) and either AAS or ICP_OES finish for
Ni, Co, MgO, FeO, Al2O3, CaO, Mn, Cr, Cu and Zn. XRF analysis of pressed powder (PP) for
Ni. Co, MgO, FeO, Al2O3, SiO2, CaO, Mn, Cr, Cu and Zn was also used initially at Goongarrie.
Nickel and cobalt assays of laboratory pulp duplicates show the analytical precision forall
threemethods to be acceptable. However, there is potentially significant bias in MgO, FeO,
Al2O3, Mn and Cr assays based of 4AD_ICP_OES and PP_XRF analyses. Both four acid
digest methods were unable to analyse for SiO2, due to incomplete digestion. As a result,
whilst the nickel and cobalt results were suitable for use in modelling, the geochemical
modelling of the Goongarrie deposits requires additional sampling and assaying, in particular
for SiO2.
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.
• A selection of samples have been analysed at an alternate laboratory (SGS Analabs) using
XRF fusion technique to verify the results reported by Ultratrace. The compared results show
a high degree of precision and no systematic bias.
• Two metre composites for the twinned RC and DD or Sonic hole pairs have been statistically
compared and determined to have similar unbiased chemical compositions for Jump Up Dam,
Highway, Goongarrie deposits. Whilst there was some variability in the geology of the close
spaced drill holes, the short range variance is typical of nickel laterite deposits in WA.
• Where geology agreed within the twinned holes, assays were generally similar between the
different methods. There was a slight negative bias in the material reporting to the fines
component of RC sampling (which includes Ni, Co, FeO, Al2O3and Mn) compared to the Sonic
drilling in some of the twinned holes at Goongarrie and Highway, and a corresponding upgrade
in coarse material (calcrete, carbonates and siliceous material).

Verification of
sampling and
assaying
(continued)
• Despite the evidence for grade differences in some of the twined holes related to the RC
drilling process, overall, the RC drilling is still considered to provide samples that
adequately represent the true geochemistry of the regolith which are suitable for the
purpose of resource estimation.
• No adjustments have been made to the 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 Resourceestimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.
• All drill holes surveyed using an RTK DGPS system with either a 3 or 7 digit accuracy. The
coordinates are stored in the exploration database referenced to the MGA Zone 51 Datum
GDA94.
• The majority of vertical holes used in the resource calculations were not down hole surveyed.
The sub-horizontal orientation of the mineralisation, combined with the soft nature of host
material would result in minimal deviation of vertical RC drill holes. All diamond holes were
down hole surveyed by an external contactor. A small number of vertical open RC holes were
check surveyed at Jump Up Dam, and found to have deviation over 60m of less than 1 metre,
which is considered sufficiently accurate for this style of mineralisation.
• The grid system for all models is GDA94. Where historic data or mine grid data has been
used it has been transformed into GDA94 from its original source grid via the appropriate
transformation. Both original and transformed data is stored in the digital database.
• Topographic control varies between the deposits. At Jump Up Dam, LIDAR data to ±10cm
vertical and ±50cm horizontal was used to generate a contour plan which was then used
construct a DTM of the topography. For Bulong existing picked up pit DTMs (from mine
surveys) were added to a DTM constructed from drill hole collars to produce a topographic
DTM post mining. For all other deposits, DTMs were constructed from picked up drill collar
locations. The use of collar data is considered sufficiently accurate for reporting of resources,
but is not suitable for mine planning and reserves.
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.
• All prospects have been drilled on uniform grids ranging from a maximum of 400mE x 100mN at
Black Range to a minimum of 10mE x 10mN in trial mining areas at Jump-up Dam. The drill
spacing at the prospects containing continuous cobalt rich mineralisation ranges from 20mE x
20mN to 80mE x 160mN at Goongarrie South, is mostly 80mE x 80mN at Big Four and Scotia,
ranges from 80mE x 160mN to 160mE x 360mN at Aubils, and is consistently 400mE x 100mN
at Black Range.
• All Heron RC samples were composited to 2 metre prior to sampling during drilling. All DD
twin holes and Vale 1 metre sampled RC holes have been digitally composited from 1 metre to
2 metre to match the RC composites prior to resource estimation.

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 drill holes is vertical and give true width of the regolith layers and
mineralisation.
• On a local scale there is some variability due to sub-vertical to vertical structures which may
not be picked up with the relatively broad spaced vertical drill pattern employed. This local
variability is not considered to be significant for the project overall, but will have local effects
on mining and scheduling later in the project life.
Sample security • The measures taken to ensure sample security. • All samples were collected and accounted for by Heron employees during drilling. All samples
were bagged into plastic bags and closed with cable ties. Samples were transported to
Kalgoorlie from site by Heron employees in sealed bulka bags.
• Consignments were transported to Ultratrace Laboratories in Perth by Coastal Midwest
Transport. All samples were transported with a manifest of sample numbers and a sample
submission form containing laboratory instructions. Any discrepancies between sample
submissions and samples received were routinelyfollowed upand accounted for.
Audits or reviews • The results of any audits or reviews of sampling techniques and data. • Heron has periodically conducted internal reviews of sampling techniques relating
to resultant exploration datasets, and larger scale reviews capturing the data from
multiple drilling programmes within the KNP.
• Internal reviews of the exploration data included the following:
oUnsurveyed drill hole collars (less than 1% of collars).
oDrill Holes with overlapping intervals (0%).
oDrill Holes with no logging data (less than 2% of holes).
oSample logging intervals beyond end of hole depths (0%).
oSamples with no assay data (from 0 to <5% for any given project, usually
related to issues with sample recovery from difficult ground conditions,
mechanical issues with drill rig, damage to sample in transport or sample
preparation).
oAssay grade ranges.
oCollar coordinate ranges
oValid hole orientation data.
• The Ultratrace Laboratory was visited by Heron staff in 2006, and the laboratory processes
and procedures were reviewed at this time and determined to be robust.
• The exploration data for the Siberia and Goongarie Regions were initially reviewed in
detail were by Heron in 2004 and subsequently by Vale / Inco in 2005

• 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 obtaininga licence to operate in the area.
• The tenement and land tenure status for the KNP prospect areas containing continuous cobalt
rich laterite mineralisation is summarised in Table 3 following and in the Ardea Prospectus,
section 9 “Solicitor’s Report on Tenements”.
Exploration
done by other
parties
• Acknowledgment and appraisal of exploration by other parties. • The Goongarrie South, Scotia, Aubil s and Jump Up Dam deposits were discovered and
explored by Heron Resources Limited.
• The Black Range deposit was initially discovered and drilled by Anaconda Nickel Limited.
• Vale Inco completed a prefeasibility study on the KNP which included extensive drilling of the
Goongarrie South and BigFour deposits relevant to the current updated resource reporting.
Geology • Deposit type, geological setting and style of mineralisation. • The KNP nickel laterite mineralisation, including cobalt rich areas is developed from the
weathering and near surface enrichment of Achaean-aged olivine-cumulate ultramafic units.
The mineralisation is usually within 60 metres of surface and can be further sub divided on
mineralogical and metallurgical characteristics into upper iron-rich material and lower
magnesium-rich material based on the ratios of iron to magnesium. The deposits are
analogous to many weathered ultramafic-hosted nickel-cobalt deposits both within Australia
and world-wide.
• Cobalt rich mineralisation is typically best developed in iron rich material in regions of deep
weathering in close proximity to major shear zones or transfer shear structures and to a
lesser extent as thin zones along the interface of ferruginous and saprolite boundaries at
shallower depths proximal to shear structures.
• The Cobalt Zone is associated with a distinctive geo-metallurgical type defined as “Clay
Upper Pyrolusitic”. Mineralogy is goethite, gibbsite and pyrolusite (strictly “asbolite” or
“cobaltian wad”). The Cobalt Zones typically occur as sub-horizontal bodies at a palaeo-
water table within the KNP (late stage supergene enrichment). This material is particularly
well developed at Goongarrie South.
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:
oeasting and northing of the drill hole collar
oelevation or RL (Reduced Level – elevation above sea level in metres)
of the drill holecollar
odip and azimuth of the hole
odown hole length and interception depth
ohole length.
• The drill hole data relating to the resource estimates reviewed in this study are all previously
reported results. No new drilling has taken place since 2008. Ongoing studies for these
prospect areas are focused on the metallurgical characteristics of the mineralisation and
development of new process technology.
• Drillhole collar, geology and assay data for each prospect area investigated in this study

Drill hole
Information
• 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.
Data
aggregation
methods
• 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.
• Most drill hole samples have been collected over 2m down hole intervals. Assay compositing
completed for each deposit in preparation for statistical analysis and grade estimation was
conducted using length weighted averaging of the input assay data by corresponding sample
lengths. Typically a 2 compositing length was used aligned with the dominant sampling interval
used for drill sample collection.
• No metal equivalent calculations have been used in this assessment.
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 (eg ‘down hole length, true width not
known’).
• The mineralisation of all Heron’s nickel laterite resources has a strong global sub-horizontal
orientation. The majority of drill holes are vertical.
• With the exception of local offsets due to slumping, all vertical drill holes intersect the
mineralisation at approximately 90 degrees to its orientation. All down hole widths approximate
true widths for vertical holes.
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.
• No new discoveries of nickel laterite mineralisation or cobalt rich areas are presented in 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.
• Not applicable to this report. All figures previously reported.

Database
integrity
• Measures taken to ensure that data has not been corrupted by, for
example, transcription or keying errors, between its initial collection and its
use for Mineral Resource estimation purposes.
• Data validation procedures used.
• Heron employed a robust procedure for the collection of and storage of sample data. This
included auto-validation of sample data on entry, cross checking of sample batches between
the laboratory and the database and regular auditing of samples during the exploration phase.
Sample numbers were both recorded manually and entered automatically. Discrepancies
within batches (samples were batched on a daily basis) were field checked at the time of data
entry, and resampled if errors could not be resolved after field inspection.
• Data validation procedures include digital validation of the database on entry (no acceptance
of overlapping intervals, duplicate hole and sample ID, incorrect legend information, out of
range assay results, incorrect pattern of QAQC in sampling stream, failed QAQC, missing
assays, samples and geological logging).
• At the time of resource modelling all data was visually checked on screen, and manually
validated against field notes. All changes to the database were verified by field checks.
Site visits • Comment on any site visits undertaken by the Competent Person and the
outcome of those visits.
• If no site visits have been undertaken indicate why this is the case.
• The Competent Person, James Ridley, is a previous employee of Heron Resources from 2004 to
2011 and has visited all of the KNP prospect areas. The drilling, sampling and geological
practices were standardized for all deposits. RC drilling was generally effective, although there
were some minor localised issues with sampling accuracy of wet puggy clays. Overall
procedures were robust, including data entry, for the RC drilling, and where tested, repeatable
by alternate drilling methods.
• The Competent Person, Ian Buchhorn, is a current employee of Heron Resources and has
acquitted and visited all of the KNP prospect areas.
• No comment can be made on the validity of historic work by Helix, WMC and Anaconda,
except to say that infill drilling has broadly similar results to the historic data. Due
diligence by Ian Buchhorn at the time of acquisition by Heron confirmed acceptable
QAQC by the various vendors.

Geological
interpretation
• Confidence in (or conversely, the uncertainty of ) the geological
interpretation of the mineral deposit.
• Nature of the data used and of any assumptions made.
• The effect, if any, of alternative interpretations on Mineral Resource
estimation.
• The use of geology in guiding and controlling Mineral Resource estimation.
• The factors affecting continuity both of grade and geology.
• There is a strong correlation between the geology of adjacent drill holes in all of theresources.
There is also a strong global correlation between weathering profile, lithology and
mineralisation intensity. On a local scale the changes in weathering profile is oftendiscrete,
butof a complex geometry. There is good confidence overall in the geological model, and this
has been confirmed at Jump Up Dam by the trial mining of 20,000 tonnes of mineralisation.
• A combination of geological logging and assay data has been used to sub divide the
mineralisation into high-iron and high-magnesium mineralisation types, within a mineralised
domain. High-carbonate domains have also been defined. High-silica domains were more
problematic to define, and further work is required on developing this geo-metallurgical domain.
• The continuity of mineralisation is strongly controlled by bed rock alteration and palaeo water
flow within the ultramafic host units. Areas of deep fracturing and water movement within the
bedrock typically had higher grade and more extensive mineralisation in the overlying regolith.
In the proximity of geological contacts between the ultramafic hosts and surrounding mafic and
felsic lithologies there is often a distinctive increase in grade and widths of mineralisation,
including the development of mineralisation along fracture planes in the adjacent felsic and
mafic units. Where the host regolith overlies olivine adcumulate lithologies there is an
increase in siliceous material and a loss of the high magnesium mineralisation horizon. In
areas where the host ultramafic was altered to talc, or talc-carbonate lithologies there was no
development of nickel mineralisation in the regolith. These areas typically formed along
shears, and sheared contacts within the bedrock.
• Mineralisation domains were developed using a combination observed geological logging, and
multi element geochemical sampling. Lower cut-off grades for the nickel domain was 0.25%
Ni for Goongarrie, Highway and Big Four deposits, and 0.4% Ni for all other domains. The
domains do contain material of lower grades where continuity of interpretation warrants the
addition of internal waste.
Dimensions • The extent and variability of the Mineral Resource expressed as length
(along strike or otherwise), plan width, and depth below surface to the upper
and lower limits of the Mineral Resource.
• Resource dimensions vary between deposits, however the resources are usually sub
horizontal, tabular with strike length over 1000 metres, widths between 100-600 metres and
thickness of 10-20 metres. Some resources outcrop, while most lie under thin (generally
less than 30 metre thick) soils, cap rock or palaeo-channel sands and clays. Most of the
modelled resources are less than 60 metres below surface.

Estimation and
modelling
techniques
• The nature and appropriateness of the estimation technique(s) applied and
key assumptions, including treatment of extreme grade values, domaining,
interpolation parameters and maximum distance of extrapolation from data
points. If a computer assisted estimation method was chosen include a
description of computer software and parameters used.
• The availability of check estimates, previous estimates and/or mine
production records and whether the Mineral Resource estimate takes
appropriate account of such data.
• The assumptions made regarding recovery of by-products.
• Estimation of deleterious elements or other non-grade variablesof
economic significance (eg sulphur for acid mine drainage characterisation).
• In the case of block model interpolation, the block size in relation to the
average sample spacing and the search employed.
• Any assumptions behind modelling of selective mining units.
• Any assumptions about correlation between variables.
• Description of how the geological interpretation was used to control the
resource estimates.
• Discussion of basis for using or not using grade cutting or capping.
• The process of validation, the checking process used, the comparison of
model data to drill hole data, and use of reconciliation data if available.
• All deposits were Ordinary Kriged (OK), using variography of the domained Ni shells for Ni,
Co, MgO, FeO, Al2O3and SiO2assay suits. (SiO2was unavailable for Siberia, Kalpini and
Ghost Rocks due to a lack of assays and was not modelled). In addition to the OK model
estimates, Uniform Conditioning (UC) was applied to nickel only for Jump Up Dam, Boyce
Creek, Aubils, Highway, Goongarrie, Big Four and Bulong deposits. Although previously
reported, these figures have not been reported in the current resource statement.
• Deposits were estimated using either Vulcan or Datamine mining software, with various
versions of Visor being employed for the variography modelling. The original domain
wireframe interpretations for Jump Up Dam were created in Micromine.
• Block sizes varied between models based on drill spacing and deposit geometry asfollows
o40 x 120 x 2 metre Siberia, Kalpini, Siberia North and Ghost Rocks
o80 x 80 x 4 metre Aubils
o40 x 80 x 2 metre Highway
o40 x 50 x 2 metre Bulong East and Taurus
o60 x 120 x 4 metre Goongarrie Hill
o40 x 40 x 4 metre Goongarrie South, Big Four
o20 x 40 x 4 metre Boyce Creek
o10 x 10 x 2 metre Jump Up Dam (global change of support was used to
calibrate the estimates within the wider spaced drillingareas)
• All models used parent cell interpolation with sub-cells half the dimension of the parent cell
to improve volume reporting.
• Ni and Co are the principal economic minerals. Fe has the potential to be an economic
mineral under some processing options being assessed. MgO, FeO, Al2O3and SiO2are all
important minerals in the classification of the different geo-metallurgical styles of mineralisation
for both materials handling and metallurgic extraction processes. All have been individually
estimated for most of the deposits using OK methods.
• The domain boundary for mineralisation is similar for all deposits with a step change in nickel
grades being modelled around the 0.4% Ni (or 0.25% Ni for Vale deposits – see geological
interpretation above) threshold using a wireframe constraint. The two sub domains within the
mineralised domain were usually geostatistically analysed and modelled separately. These
internal domains relate to the high-iron, and high-MgO domains, which form the upper and
lower portions of the mineralised weathering profile, and are usually separated by a sharp
(although often geometrically complex) geological boundary. (Note: for some deposits only
one or other geochemical domain is present). Depending on results of the variography,

geochemical domains within the nickel wireframe shell.

Criteria JORC Code explanation Commentary
No shells were developed for cobalt or any other minerals, and grades were interpolated into
the same domain.
• All deposits have been previously modelled, and were checked against previous models to
confirm the expected changes between models.
• Model estimates were validated against drilling by comparing input and output means, moving
window comparative means and by visual inspection of the models. The results of these
investigations were generally acceptable for level of resource confidence applied to each
model.
• In the case of Jump Up dam, where trial mining has taken place, reconciliation between
measured resources and mining was very good for both nickel and cobalt. There were some
discrepancies in the modelled mineralogical classification of the mineralisation which will have
a local effect on processing, depending on the process method employed. These
discrepancies were related to the highly complex geometry of the interface between high and
low magnesium portions of the deposit, even within a 10 metre spaced drilling grid.
Moisture • Whether the tonnages are estimated on a dry basis or with natural
moisture, and the method of determination of the moisture content.
• All tonnages reported are dry tonnes for all models. Dry density was determined from drill core
and down hole gamma for the Jump Up Dam, Scotia, Highway and Goongarrie deposits. This
dry tonnage was applied to the other deposits on a material type basis (see Bulk Density for
more details).
Cut-off
parameters
• The basis of the adopted cut-off grade(s) or quality parameters applied. • The 0.25 and 0.4% Ni cut-offs used for the wireframe domains of the deposits was based on
two observed step changes in nickel grades across the drill holes.
• Routine Mineral Resource reporting by Heron has a 0.5%Ni cutoff grade applied to the
resource block models as this is a common lower grade cut employed during mining of Nickel
Laterite deposits.
• RMRC produced block model grade shells using a 0.08% Co cutoff which were then trimmed
in order to provide constraints for updated Mineral Resource reporting relating to regions of
continuous cobalt mineralisation in the Goongarrie South, Big Four, Scotia and Aubils
prospect areas. These cobalt rich areas are of particular interest to Heron as a potential
source cobalt-nickel-manganese feedstocks for the lithium ion batteryindustry.

Mining factors
or assumptions
• Assumptions made regarding possible mining methods, minimum mining
dimensions and internal (or, if applicable, external) mining dilution. It is
always necessary as part of the process of determining reasonable
prospects for eventual economic extraction to consider potential mining
methods, but the assumptions made regarding mining methods and
parameters when estimating Mineral Resources may not always be
rigorous. Where this is the case, this should be reported with an
explanation of the basis of the mining assumptions made.
• Open pit mining via conventional dig and haul with minimum blasting is assumed for all
deposits. Given the lateral extent of the models the selective mining unit SMU is likely to be
10x10x4(or 2) metres and this was used to develop the uniform conditional model grades for
nickel for the deposits.
• For the purposes of removing unlikely to be economic resources from the resource statement,
a Whittle optimization of the KNP and Yerilla deposits was carried out using an A$12.50 per
pound nickel price. Mining and processing costs, along with royalty and recovery factors were
taken from the 2010 Heron PFS mining study for this process. The evaluation was carried out
on the Kriged nickel and cobalt grades only (uniform conditioning models were not used).

Metallurgical
factors or
assumptions
• The basis for assumptions or predictions regarding metallurgical
amenability. It is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider potential
metallurgical methods, but the assumptions regarding metallurgical
treatment processes and parameters made when reporting Mineral
Resources may not always be rigorous. Where this is the case, this should
be reported with an explanation of the basis of the metallurgical
assumptions made.
• The KNP and Yerilla Projects are both subject to ongoing metallurgical studies. Processes
being considered include, heap leaching, vat leaching, high pressure acid leaching, screen
upgrades prior to leaching and pyrometallurical methods. All methods are capable of
processing Nickel Laterite ore types into saleable products and are currently in use at different
deposits across the world.
• The current focus of studies into a preferred metallurgical approach is on atmospheric acid
leaching methods with a particular focus on improving the recovery of reagents during
processingto improve unit costs.
Environmental
factors or
assumptions
• Assumptions made regarding possible waste and process residue disposal
options. It is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider the
potential environmental impacts of the mining and processing operation.
While at this stage the determination of potential environmental impacts,
particularly for a greenfields project, may not always be well advanced, the
status of early consideration of these potential environmental impacts
should be reported. Where these aspects have not been considered this
should be reported with an explanation of the environmental assumptions
made.
• It is expected that waste rock material will largely be disposed of inside previously completed
pits during the life of mine. Tailings disposal will consist of a mixture of conventional tailings
dams and disposal in mined out pits. As all of the material mined will be of an oxidized nature,
there is not expected to any acid generating minerals in the waste rock material. The
processed tailings will need to be neutralized or recovered from the tailings stream prior to
disposal in waste storage facilities. The expected land forms at the conclusion of the project
will be of similar profile to the current land forms.
• Environmental studies for the project have been started with base line surveys for flora and
fauna. However, as the final process route is currently subject to research, the final
environmental plans are yet to be developed. It is reasonable, given the existing nickel laterite
operations in WA, that all environmental issues can be resolved and it will be possible to mine
the resources within current environmental guidelines.

that adequately account for void spaces (vugs, porosity, etc), moisture and
differences between rock and alteration zones within the deposit.
• Discuss assumptions for bulk density estimates used in the evaluation
process of the different materials.
• Bulk densities were measured for the Jump Up Dam, Goongarrie and Highway, by both
gamma down hole measurements, weight of recovered core versus drilled volume and wet/dry
density measurement of drill core. Both the wet/dry and weight of recovered core methods
include voids in the density assessment. The three measurements all gave similar reading for
the in-situ density of the material (including any moisture within the in-situ material). Changes
in mass were recorded for the recovered core between its as drilled mass, and mass after kiln
drying to apply moisture content to the density measurements producing a dry density for
resource estimation purposes. The variance in measured dry density was between 1.3 and
2.05/m3for all material types. Most of the mineralisation lies within the ‘clay’ material which
has a dry density of between 1.30 and 1.33t/m3. Densities were assigned to material based on
the geochemical material classification scheme for each of the deposits.
• All other deposits were not measured in the field. Densities based on the above
measurements were applied to similar geology on these deposits, using either the
geochemical material classification scheme, or, where assays not sufficient for classification,
the average density for clay material.
Criteria JORC Code explanation Commentary
Classification • The basis for the classification of the Mineral Resources into varying
confidence categories.
• Whether appropriate account has been taken of all relevant factors (ie
relative confidence in tonnage/grade estimations, reliability of input data,
confidence in continuity of geology and metal values, quality, quantity and
distribution of the data).
• Whether the result appropriately reflects the Competent Person’s view of
the deposit.
• Classification varied slightly between the deposits. All classification of resource estimates
were based on a combination of drill hole spacing, the ranges of mineralisation continuity
(developed from variography studies), availability of all assay suits for geochemical
classification and the slope of regression of the ordinary kriged nickel estimates.
Measured Mineral Resource

Drill spacing of 20x40 metre or less.

All assays (Ni, Co, MgO, Mn, Cr, AL2O3,Si02, FeO, MgO, CaO) available for
geochemical classification.

Criteria JORC Code explanation Commentary
Audits or
reviews
• The results of any audits or reviews of Mineral Resource estimates. • All resource estimates attributed to Snowden were reviewed internally by Snowden at the time
of their creation, and externally by Heron. Models created in-house by Heron have been
validated against previous models created by Snowden. All models have been checked by
Heron employees both past and present and are considered to be reasonable estimates of
resources given the level of confidence applied to each model.
Discussion of
relative
accuracy/
confidence
• Where appropriate a statement of the relative accuracy and confidence
level in the Mineral Resource estimate using an approach or procedure
deemed appropriate by the Competent Person. For example, the
application of statistical or geostatistical procedures to quantify the relative
accuracy of the resource within stated confidence limits, or, if such an
approach is not deemed appropriate, a qualitative discussion of the factors
that could affect the relative accuracy and confidence of the estimate.
• The statement should specify whether it relates to global or local estimates,
and, if local, state the relevant tonnages, which should be relevant to
technical and economic evaluation. Documentation should include
assumptions made and the procedures used.
• These statements of relative accuracy and confidence of the estimate should
be compared with production data, where available.
• All models as reported provide reasonable global estimates of the available nickel and cobalt
resources. Models have been validated visually against drilling for both the recoverable
minerals nickel and cobalt, and important geo-metallurgical minerals modelled (FeO, MgO,
Al2O3,CaO and SiO2).
• The measured resources trial mined at Jump Up Dam reconciled to within 5% of both tonnes
mined and nickel grade of mined material (note this reconciliation is an “as-mined”
reconciliation, as the material mined has not been processed to date). In the trial mine there
were some significant departures in modelled geo-metallurgical material type, no doubt partially
due to the small sample size of the mining volume, but also reflecting the short range
complexity of the MgO horizon and difficulties in mining of the highly variable contact zone.
• Overall the modelled resources present a very reasonable global estimate of the resources for
Ni and Co. The also provide a reasonable global estimate for MgO, FeO and Al2O3estimates
within the ore domains. Where measured material has been modelled (ie 10x10 metre spaced
drilling), thelocalestimate of nickeland cobaltreconciledwell within industry standards.

  • KNP Cobalt Zone has a JORC 2012-compliant resource of 49.7Mt at 0.12% cobalt and 0.86% nickel

  • Cobalt-enriched zones are contained within and are a subset of the broader KNP resource of 805Mt at 0.05% cobalt and 0.7% nickel[1] , being Australia and the developed world’s largest cobalt resource

  • KNP Chrysoprase (semi-precious gemstone) mechanised bulk production opportunity identified

  • Lewis Ponds

  • Bulk tonnage Exploration Target defined

  • Significant base metal-gold open-pit potential, with orogenic gold and base metal mineralisation defined which is very similar to other large deposits in the region

  • Lewis Ponds Main Zone and Tom’s Zone main shaft mullock sampling by Ardea returned assays of 9.9–12.1g/t gold and 272–539g/t silver, possible epithermal mineralised affinity

  • New tenement applications complementing existing Ardea projects

  • Lewis Ponds, NSW – several licence applications secured and already recommended for grant

  • Bedonia West and Perrinvale, WA – high quality Ni-Cu-PGM targets acquired

Heron Resources Limited (Heron or Company) is pleased to provide an update on Ardea Resources Limited (Ardea) and its project activities, as disclosed in the prospectus (Prospectus) lodged with the Australian Securities and Investments Commission on 9 November 2016 and Supplementary Prospectus lodged 18 November 2016.

Figure 4 - Goongarrie South – work currently underway, showing 0.08% Co trimmed block model grade shell

1.1.1. Goongarrie South

The resource estimation reviewed existing KNP 0.5% Ni cutoff grade blocks which coincidentally exceed 0.08% Co and where they define coherent mining shapes. These grade shells were subsequently trimmed on an individual wireframe basis, excluding wireframe pods with less than three mineralised drillhole intersections, except where nearby adjacent drillhole intersections demonstrate continuity of the mineralisation above the 0.08% Co cut-off grade.

The cobalt review included the Goongarrie South–Big Four– Scotia Dam resource belt. This area will clearly will be the focus of Ardea’s future cobalt program.

The current working concept is a Goongarrie South to Scotia Dam production rate of 2Mtpa at 0.12% Co and 0.94% Ni for approximately 2ktpa cobalt in intermediate product (a cobaltand nickel-bearing manganese oxide) with in addition some 16ktpa nickel (distributed between battery feedstock and conventional nickel refinery feed). Plant site location would be at Goongarrie South at the northern end of the cobalt belt, with initial mine scheduling being a zone at Goongarrie South termed the “Pamela Jean Deeps”.

1.1.2. KNP, Australia’s largest cobalt resource

Containing 386,400 tonnes of contained cobalt metal, the KNP is Australia’s largest cobalt deposit. By this measure, it is more than three times larger than Australia’s second

largest cobalt deposit. The newly-reported cobalt resource from the high-grade KNP Cobalt Zone is a subset of the larger KNP resource, and this subset is by itself Australia’s fourth largest cobalt resource, containing 59,600 tonnes of cobalt metal. The KNP Cobalt Zone also has one of the highest cobalt grades in Australia.

The updated resource reporting for cobalt-rich zones provides an insight into the potential to define further cobalt-rich zones in the KNP on the basis of remodeling work planned by Ardea that is focused on cobalt. Updated resource reporting on the cobalt-rich mineralisation at the KNP marks the first part of a refocusing for the KNP onto the cobalt component of the deposit.

Forthcoming drilling and metallurgical studies will move the KNP towards a PFS focusing on feedstocks for the lithium ion battery industry (Lithium Nickel Manganese Cobalt Oxide - LiNiMnCoO2 or NMC).

The drilling focus in ranking will be the contiguous cobalt zones in the Goongarrie South belt and at Black Range and Kalpini. The drilling will secure material for bench-scale metallurgical assessment.

1.2. Semi-precious gemstones within the KNP – Chrysoprase (“Australian Jade”)

The Kalgoorlie Nickel Project is characterised by widespread occurrences of the semi-precious gemstone chrysoprase. Chrysoprase is a rare, highly valued, nickel-bearing variety of chalcedony. Colour varies from apple green to deep green, and the highest quality material is translucent. Chrysoprase is commonly known by gemologists as “Australian jade” and is often used in jewellery as a substitute for jade due to its harder wearing characteristics. Chrysoprase is highly valued in east Asia notably China.

The occurrence of chrysoprase in shallow strongly weathered horizons throughout the KNP is directly analogous to the occurrence of opal in the opal fields of Coober Pedy (SA) and Lightning Ridge (NSW). As in the opal fields, chrysoprase has developed in veins within cracks and crevices in the clay-rich host rocks. In the KNP, the highest quality, deepest green chrysoprase shows a direct spatial relationship to the cobalt- and nickel-rich parts of the orebodies. Ardea has defined five advanced stage chrysoprase pit opportunities within the KNP.

Figure 5 - As mined chrysoprase, KNP. Indicative value $8-20 per kilogram. Forecasts of chrysoprase values are very difficult due to a lack of open markets, and confirm the desirability of securing a partnership with a downstream gemstone processor

Ardea estimates open-pit mining costs of approximately $6/t with runof-mine chrysoprase valued at approximately $8-20/kg, and gem quality in excess of $20/kg (breakeven grade 1kg/t of lower quality chrysoprase). Kalgoorlie chrysoprase mining has traditionally been labourintensive and conducted by small scale tributers. Ardea has scoped a mechanised production model using ore sorting technology.

Ardea believes an east Asia jewellery producer would be a preferred chrysoprase development partner.

2. Lewis Ponds zinc-gold project – Updates

2.1. Bulk tonnage model for exploration and development

At Lewis Ponds, “ the mineralisation is accepted as Volcanogenic Massive Sulphide (VMS) type ” (Prospectus, page 46). The mineralisation as described is multiple lenses (1, 2 and 3) of massive stratabound base metal sulphides hosted within the Anson Formation pyritic siltstones. Exploration has historically been on the basis of a narrow high grade underground mining model, and has generated a mineral resource totaling 6.6Mt at 1.5g/t gold and 2.4% zinc[2] estimated at a 3% ZnEq cut-off grade (refer Prospectus Table 3.2 for full description of resource status).

As noted in the Prospectus (page 44), Lewis Ponds “ occurs on the Lewis Ponds Fault; a subsidiary fault to the Godolphin Fault. The region is well known for being prospective for a variety of deposit types, especially VMS deposits and orogenic gold deposits .”

Having now completed regional geological orientation programs in the Lewis Ponds area, it is clear that Lewis Ponds has a significant potential for orogenic gold deposits of the style of Regis Resources’ McPhillamys deposit, located “ 15km south along the Godolphin Fault ” from Lewis Ponds (Prospectus page 44).

As well as the traditional zinc-dominant VMS model, there is now a requirement to additionally evaluate Lewis Ponds as a bulk tonnage orogenic gold-base metal system, with the clear mining model being McPhillamys (resource 73Mt at 0.93g/t Au at 0.4g/t Au cut-off grade, Regis Resources, 31 March 2015).

ASX/TSX Release 6 January 2016

There are very clear geo-metallurgical associations at Lewis Ponds, possibly representing separate mineralising events, in order of abundance:

  1. Dominant Zn-Pb-Ag-Au (stringer dominant but significant massive sulphide interbands).

  2. Au-Ag only (which is poorly sampled, thus difficult to quantify as an orogenic gold system).

  3. Minor Zn-Pb only.

  4. Rare Cu only, always in the footwall.

Lewis Ponds mineralisation is dominantly a 20-50 metre wide stringer (shear vein) system with 2-10 metre thick bands of massive Zn-Pb-Ag-Au mineralisation able to carry sub-grade stringers, with typically 2-5 m internal waste bands.

The mining implications for Lewis Ponds are:

  • Drill intercepts are required to be bulked into broad lower grade intervals of the McPhillamys style, using a 1% ZnEq cut-off (approximately 0.5g/t AuEq).

  • Open-pit bulk mining is more likely to be feasible, given the favourable Lewis Ponds strip ratios and consistent shallow high-grade mineralised occurrences.

At Lewis Ponds, the bulk tonnage potential is confirmed in Prospectus Figure 3.3 (refer gold-equivalent calculation), with the following gold-equivalent intercepts on Section 940mN representative of the overall Lewis Ponds mineralised system.

  • Western Lode

  • TLPRC-02 90m at 1.02g/t AuEq from 18m

  • o SLP-7 27m at 1.59g/t AuEq from 62m

  • TLPD-02W 30m at 2.44g/t AuEq from 271m

  • Central Lode

  • LPRC-32 54m at 1.72g/t AuEq from 26m

  • TLPD-40 37m at 0.92g/t AuEq from 199m

  • Eastern Lode

  • TLPD-40 68m at 0.97g/t AuEq from 57m

Having now completed field reconnaissance, it is felt that Lewis Ponds is better evaluated as a base metal-gold stringer system. Table 2 summarises the more significant “bulk-tonnage” intercepts at Lewis Ponds. More detailed drill intercept data has been previously published by TriAusMin Limited in ASX announcements between 2002 to 2014 (Prospectus page 71) and these reports may be obtained from Ardea.

From reviewing available drill core at site and archived core photographs, it is clear that extensive zones of sericite-pyrite alteration (potential gold mineralised host) have not been sampled. There is thus a requirement to cut and sample this core (assuming the individual core is still available), with the potential to establish “McPhillamy-style” mineralised systems.

The Ardea intention is to drill a single orientated core hole on Sections 1000mN, 800mN, 600mN and 400mN, and all available core on these 200 metre spaced sections will be re-logged, re-photographed and assayed.

This program will act as a control to allow a resource update based on bulk-tonnage parameters. The known high grade zone extends from Section 300mN to Section 1500mN and ultimately all historic drill holes within this zone will require relogging and assay. This requirement was not anticipated within the Prospectus work program and has arisen through field studies subsequent to November 2016 Prospectus lodgment.

2.2. Field exploration results

Whilst siting drill collars for the initial proposed Ardea drill program, a suite of samples was collected as a first pass in defining Lewis Ponds geo-metallurgical types (GeoMet study). At the old Lewis Ponds Main Zone and Tom’s Zone main shafts, the main producers in the field, it was apparent that the dominant shaft mullock at both locations (600m apart along strike) is a distinctive white vuggy quartz-pyrite “sinter” (which appeared to have the appearance of epithermal style mineralization).

The high-grade Au-Ag with anomalous As-Sb is consistent with epithermal style mineralisation, and the low base metal values are not indicative of a VMS setting at the shaft areas.

Base metal and gold production is unknown for the Lewis Ponds shaft. Toms produced 30,000 tonnes of pyrite ore for sulphuric acid production. It is puzzling that such high grade precious metal mineralisation remains at both locations as shaft mullock and was not treated in the historic operation.

This mineralisation style was not predicted within the Prospectus and is of significant economic potential. In particular, “Gold Stringer” is a geo-metallurgical type recognized in Ardea’s work but not described in historic Lewis Ponds records.

Drill approval environmental submissions are being prepared, with Department of Resources and Energy approvals anticipated in time for February 2017 drilling.

2.3. Exploration target

In consideration of the broad mineralised intercepts over a strike length of 1.15km between Section 350mN and Section1500mN, the initial Lewis Ponds Exploration Target is estimated at 15 - 25Mt at 2.2 - 3.7% ZnEq (1.2 -2.0g/t AuEq)[3] (see Table 2 for values used in defining zinc and gold equivalents). The estimated breakeven mining grade is 1.6% ZnEq.

The potential quantity and grade is conceptual in nature, and there has been insufficient exploration based on the “bulktonnage” concept to estimate a mineral resource and it is uncertain if further exploration will result in the estimation of a “bulk tonnage” mineral resource.

The system is open north and south along strike within areas of historic workings and soil geochemical anomalism. Significantly, there are extensive runs of historic drill core with no assays at all or only base metal assays (i.e. no gold assays).

Commonly within the Lewis Ponds lode envelopes, the runs of non-assayed material correspond to core photography which clearly shows the core is altered and likely mineralised. These intervals are ascribed nil grade within intercept calculations, meaning the Exploration Target grade is likely under-estimated.

Funds raised under Ardea’s initial public offer will be used, amongst other things, to test the exploration target through diamond drilling on 100 metre spaced sections over the next 12 months.

3. Exploration update

3.1. Western Australian projects

As exploration ramps up, Ardea intends to consolidate its substantial portfolio of exploration tenements in the Eastern Goldfields of Western Australia that are prospective for Archean-style nickel sulphide and gold mineralisation. The consolidation process has commenced.

3.1.1.Mt Zephyr Gold-Nickel Project - Ardea 100%

Mt Zephyr is a section of greenstone belt localised on the Celia Lineament and located 60km NNE of Leonora.

Referring to section 2(a) of the Supplementary Prospectus dated 18 November 2016, the objection to the grant of the main tenement has been withdrawn and accordingly the tenement has been recommended for grant. An archaeologist for assessing proposed Gale and Dunns New Find drill sites has been retained.

Gale gold prospect

Gale is a 273ppb Au soil anomaly which Aurora Gold[5] RAB drilled in the 1990s and intersected consistent >0.25g/t Au from surface to RAB refusal with intercepts of 6-18m at 0.5g/t Au and peak 6m at 1.3g/t Au. The anomaly is clearly a sub-horizontal geometry and not the narrow sub-vertical interpretation of previous explorers.

The Gale RAB gold anomaly at a 0.25g/t Au cut-off grade defines an open sub-horizontal sheet with 700m N-S strike, 100m E-W width with up to 18m thick (corresponding to RAB refusal depths).

A site visit confirmed the anomaly has not been followed up with previous RC drilling, apart from a very limited program at the extreme northwest corner of the soil anomaly. Old RAB chips mixed with aeolian sand located at the old RAB collars returned consistent 0.1-0.4g/t Au. RAB chips included silica-pyrite-sericite alteration, which have the appearance of a “late stage mineraliser”. The geological expression of Gale is felt to be closely analogous to the Dacian Gold Jupiter syenitehosted gold discovery, located 50km southeast along strike on the Celia Lineament.

3 An Exploration Target is a term used within the JORC2012 Code for an estimate of the exploration potential of a mineral deposit. As used in this release the stated Exploration Target is based upon the parameters described in the text, however the potential quantity and grade is conceptual in nature and there is insufficient information to estimate a Mineral Resource and it remains uncertain if further exploration will result in the estimation of a Mineral Resource in this area of drilling.

5 Aurora Gold has not consented to the use of the historical geological report reference in this announcement. The potential quantity and grade of any mineralisation is conceptual in nature, there has been insufficient exploration to estimate a mineral resource and it is uncertain if further exploration will result in the estimation of a mineral resource.

Heron Resources Limited

ASX/TSX Release 6 January 2016

The RAB chip anomalism is supported by up to 1.4 g/t Au in an “unaltered” granite float composite south of the RAB-drilled area, and 1.2-1.5g/t Au in gossanous limonite-white quartz vein float to the east of the RAB-drilled area.

The observed sub-horizontal RAB litho-geochemistry is a primary protolith attribute, since very clear-cut sharp barren RAB assays occur at the east and west contacts (if solely a supergene blanket enrichment, diffuse contacts with wider and more gradual dispersion would be expected).

Ardea plans to follow up the Gale RAB anomaly with systematic RC drill traverses.

Figure 8 – Mt Zephyr, tenement and key prospects map

Dunns Line of gold prospects

The model for gold mineralisation has been refined with the recognition that historic workings are closely associated with NE trending cross-faults within the N-S trending main BIF horizon. Ardea’s exploration model has evolved to be closely analogous to the Hill 50 “Boogardie Breaks” at Mt Magnet in Western Australia.

Rock chip and historic percussion drill chips along the target zone were sampled. It is planned to complete systematic soil auger geochemistry along the 4km of exposures along Dunns Line and extending into soil covered (altered) areas along strike of the main BIF.

Jones Area A and B nickel sulphide prospects

Olivine adcumulate komatiite channel facies have been identified by Ardea within a stratigraphic horizon which is felt to correlate with the Mt Windarra nickel sulphide mine stratigraphy. A sulphide facies BIF underlies the komatiite channel at Jones A, which is an excellent setting for “Silver Swan-style” nickel sulphide occurrences. Ironstone assays by Ardea at Jones Area B returned 0.3% Ni, confirming a prospective nickel sulphide setting.

Soil auger geochemistry is planned ahead of ground EM surveys.

There has been no previous RC drill testing of the Jones targets.

The Mt Zephyr E39/1854 application containing the Gale, Dunns and Jones prospects has been recommended for grant and consultant retained for a heritage survey.

Ghost Rocks gold prospect

The Lady Isobel group of workings trend NNW over an area of 170m x 70m. The workings include a substantial underlay shaft dipping approximately 45[0] towards 120[0] (discordant to the overall trend of workings), with smaller subsidiary workings distributed over the full area on multiple structural orientations. Mullock consists of white quartz vein stockworks within an amphibolite host.

Random mullock sampling by Ardea on the main shaft assayed up to 5.3 g/t Au. There appears to be a deficiency of mullock when considering the depth of shafts, suggesting part of the excavated material has been milled.

Big Four gold prospect

The Big Four gold prospect is being evaluated as a potential open-pit. The main lode has excellent visual expression, being a subvertical quartz lode within clay-limonite altered dioritic porphyry. Visual grade control should be possible in any open-pit mining.

Reconnaissance in late 2016 was aimed at assessing additional exploration targets along strike, notably soil geochemical anomalies to the south.

The target concept at Big Four is an open-pit developed over the historic workings. Elsewhere in the Bardoc Tectonic Zone (BTZ), such occurrences were drilled and mined during the various “gold booms” of the 1990-2000s. With Heron’s historical focus on the KNP nickel laterite within the BTZ tenure, gold exploration was minimal.

A proposal was received by Ardea from a local contractor to complete a trial pit at Big Four under a profit share arrangement. In view of open ore positions at Big Four, it was concluded that further exploration was required at Big Four before a transaction could be considered.

Various gold joint ventures were also proposed, but decisions will await completion of the Ardea IPO.

4. Tenement acquisition update

Ardea has applied for several new tenements in New South Wales and Western Australia, subsequent to the Ardea Prospectus “Technical Assessment Report” and so these projects are not covered in the Prospectus. The following sections briefly describe the geology and prospectivity of these new project areas.

4.1. Lachlan Fold Belt, NSW

As part of the Ardea Prospectus preparation, a significant gold prospect has been generated for the Lewis Ponds project around the Godolphin Fault, a shallow east-dipping domain boundary structure separating the Ordovician Macquarie Arc in the west from the Silurian Hill End Trough in the east. From southeast to northwest, the structure hosts gold mining centres and targets from McPhillamys, Springfield, Mt Shorter, Calula and Copper Hill East. This Godolphin Fault trend is held within Ardea’s tenement package, a 50km strike of continuous tenure abutting the McPhillamy’s deposit in the south and the Commonwealth (Silica Hill) deposit in the north.

4.1.1.Yeoval Porphyry Copper-Gold-Molybdenum-Rhenium Project (ELA5368, recommended for grant) - Ardea 100%

Yeoval (ELA 5368) is located within the Macquarie Arc, 60km northeast of the Northparkes copper-gold mine. The tenement application covers an area of 138km[2] and is intensely mineralised with more than 60 historic copper workings trending in a north-easterly direction, along a 20km strike. The project area encompasses the eastern section of the Early Devonian

Yeoval Complex, with the major host being the Devonian-aged Naringla Granodiorite including gabbro-diorite and quartz

monzo-diorites. The co-magmatic Canowindra Volcanics of the Cudal Group occur to the east and south. The Ardea exploration target is a large tonnage porphyry copper-gold-molybdenum-rhenium system.

This report section contains exploration results and estimates reported by ASX-listed Augur Resources Limited on 17 September 2012 under the JORC Code 2004[7] . The information has not been updated to comply with the JORC Code 2012, and it is uncertain whether following evaluation or further exploration work that the estimate will be able to be reported in accordance with the JORC Code 2012.

The known Yeoval deposit comprises two main near-surface zones of bornite-chalcopyrite mineralisation. Initial drilling in 1972 produced best intercepts of 42.7m at 0.93% Cu and 18m at 0.8g/t Au. Drilling in 2008 by Augur Resources produced best intercepts of 90m at 0.90% Cu and 0.14g/t Au and 50m at 0.54% Cu and 0.48g/t Au. Augur Resources[9] reported on 17 September and 2 December 2008 an Inferred Mineral Resource in compliance with JORC 2004 guidelines and based on this, Augur Resources considered an Exploration Target of approximately 10Mt – 13Mt at grades of approximately 0.38% Cu and 0.14g/t Au as achievable.[10]

This table represents data from an Augur Resources announcement on 17 September 2012 to the ASX. The background details of the data have yet to be ascertained and application has been made by Ardea to the NSW Department regarding release of the relevant comprehensive data-set to open file. The above information is included to validate that the Yeoval deposit is significantly copper-gold endowed and so warrants further investigation. Copies of Augur’s several Yeoval announcements are available by contacting Ardea.

4.1.2.Mt Aubrey Epithermal Gold-Silver Project (ELA5369, recommended for grant) - Ardea 100%

Mt Aubrey (ELA 5369) is located at the east contact of the Macquarie Arc Ordovician andesites some 30km northeast of Parkes and 30km southeast of Peak Hill.

The property was acquired by Ardea as an epithermal gold system hosted in Upper Silurian to Lower Devonian-aged Dulladerry Volcanics, a bimodal subaerial suite of quartz eye porphyry with rhyolitic ash-flow lapilli tuff, pyroclastic and breccia and amygdaloidal basalt. Gold mineralisation is typically hosted by 0.5-3m thick chalcedonic epithermal quartz veins and stockworks. All assays reported in Table 5 below are from open file reports and are not able to be verified by Ardea.

Although an epithermal-style of gold mineralisation, the Mt Aubrey mineralisation isn’t refractory, with the published run-ofmine grade (3.73g/t Au) returning 95.7% recovery in historic metallurgical test work.

Gold mineralisation at the Mt Aubrey vein system remains open at depth and along strike, as the historical drilling done by BHP Gold was only designed to define shallow oxide resources. The Mount Aubrey deposit was mined by BHP Gold in 1990 and 1991 as shallow open-pit satellite operations to the Parkes Gold Mine. It is estimated that up to 120,000 tonnes of ore at 3.3g/t Au was trucked to Parkes for processing. As part of the operating agreement with the landowner all three of the small open-pits were back filled.

It is presumed that the shallower of the drill intercepts as reported above were mined in the BHP open-pits. Historic pit pickups will be sought to quantify the status ore positions beneath the historic pit floors.

7 Augur Resources has not consented to the use of the historical geological report reference in this announcement. This section contains exploration results and estimates reported by Augur Resources Limited on 17 September 2012 under the JORC Code 2004. The information has not been updated to comply with the JORC Code 2012, and it is uncertain whether following evaluation and or further exploration work that the estimate will be able to be reported in accordance with the JORC Code 2012.

10 The potential quantity and grade is conceptual in nature and there is insufficient information to estimate a Mineral Resource and it remains uncertain if further exploration will result in the estimation of a Mineral Resource in this area of drilling.

In 2007, Aurelia Metals Limited[14] completed three diamond core holes beneath the former Mt Aubrey Gold Mine for a total of 916.6m. The holes were designed to test the down dip extension of high grade epithermal quartz veining mined in the Mt Aubrey open-pits. Holes MAD002 and MAD003 each intersected broad zones of epithermal quartz-carbonate vein stockworks associated with epidote, sericite and bleaching alteration and minor sulphides.

It is yet to be determined through historic pit surveys which of these intercepts have been extracted in previous mining operations. Anecdotal reporting suggests very shallow open-pits, being some 2030m deep as determined by stripping ratios. Their inclusion in this Report is solely to demonstrate that the Mt Aubrey system is gold-endowed and warrants further evaluation.

At the Mt Aubrey South prospect drill hole MAD004 intersected a broad zone hosting abundant mineralised crustiform textured quartz-carbonate-pyrite veining with a gold intersection of 88m at 0.22g/t Au from 2m. The gold mineralisation in MAD004 represents an un-mined new gold-bearing structure to the south of the main Mt Aubrey vein system.

The Blue Hills prospect is an area of outcropping, gold bearing veins and minor workings 2km along strike to the northwest of Mount Aubrey. Rock chip samples of up to 13.4g/t Au have been recorded and two costeans returned results of 2m at 1.35g/t Au and 6.5m at 1.40g/t Au. The area between Mt Aubrey and Blue Hills is mainly covered by modern alluvium but is also thought to contain quartz veining.

The Emu Swamp prospect is located 3km to the east of Mt Aubrey and contains outcropping veining with rock chip gold values to 3.3 g/t Au associated with pyritic alteration. The 6km Blue Hills – Mt Aubrey – Emu Swamp trend represents a significant epithermal vein system target.

Mt Aubrey along with the adjoining Yeoval tenure is interpreted by Ardea as the manifestation of a major NE-trending zoned porphyry copper-gold-molybdenum-rhenium to epithermal gold-silver intrusive centre.

4.1.3.Wiseman’s Creek Gold-Copper Project (ELA5378, recommended for grant) - Ardea 100%

The Black Bullock prospect is located at Wiseman’s Creek, 35km southeast of Bathurst, NSW. Epithermal gold mineralisation within the tenure is hosted largely within Late-Silurian – Early Devonian-aged slates, shales and sediments of

the Kildrummie and Campbell’s Groups, with geology through the centre of the tenure comprising the andesitic Ordovicianaged Rockley Volcanics.

Mineralisation has been reported as predominantly associated with silicified zones with epithermal textures such as openspace filling in quartz veins, quartz vein breccias, chalcedonic silicification and colloform banding. The units strike NNW and dip steeply eastwards.

The Wiseman’s Creek area was held as EL2098 by Windsor Resources[16] during the 1980s and was part of a JV arrangement, which saw a total of 80 RC and three diamond holes drilled between the years 1985 - 1989. In Windsor’s 1988 Annual Operations report, the major historic gold mine production was noted as being from Black Bullock Mine, reporting production of some 40,000oz of silver and 2,098oz of gold from 4,700 tonnes of ore (at an average grade of 14g/t gold). Three main areas of interest were identified, some within State Forest and some on freehold land.

At the gold prices of the day, the deposit was not considered economic, however gold intercepts at shallow depths were reported that warrant further investigation. Table 6 above lists only some of the more significant gold intercepts recorded in the Windsor Annual Report. An additional 23 RC and 3 diamond drill holes (not listed in Table 6) contained significant intercepts at or above 0.5g/t Au. In 2006 Central West Gold[17] completed an IP survey and drilled follow up RC holes based on modelling of the earlier historic drilling and which reportedly contained a best result of 3m at 0.36g/t Au from 9m.

The quality of the data has yet to be ascertained as historic QAQC work was poorly reported, but is included to establish that the Wiseman’s Creek prospect is gold-endowed and warrants further investigation.

Duckmaloi Tungsten prospect

From 2012 to 2014 part of the tenement area now held by Ardea was held by Resmetco Ltd[20] who explored for tungsten within a prospect known as “Duckmaloi” hosted within skarn style mineralisation. The prospect itself was estimated in an open file report to have an Exploration Target[1] of approximately 375,000 tonnes at 0.2% WO3 The potential quantity and grade is conceptual in nature and there is insufficient information to estimate a Mineral Resource and it remains uncertain if further exploration will result in the estimation of a Mineral Resource in this area of drilling.

The existence of this deposit style as well as the nearby epithermal occurrences does suggest evidence for a larger mineralizing system and also warrants further investigation.

Statement), 95-106 (Tenements).

Heron Annual Report 2016 dated 24
August 2016, section 10.6.

Heron Quarterly Report September
2016 dated 31 October 2016.
Both Reverse Circulation Percussion drilling
(RCP) and Diamond core drilling (DD) have
contributed to the Lewis Ponds resource
database.
RCP totals 2,190 samples
representing 2,566 metres of mineralisation
drilling, and DD totals 4,832 samples for 5,048
metres. Total drilling to the date of the Bob
Cotton September 2016 report was 54,516
metres comprising:

117 primary diamond holes for 41,776
metres

32 wedged diamond holes for 7,159
metres

7 diamond tails to RCP holes for 159
metres

62 RCP holes for 5,421 metres

4 Open Holes (Percussion/Rotary
drilling) for 276 metres

The last hole drilled was the diamond
tail to TLPRC04010.
 The Resource is based on sub-surface
samples obtained by the above drilling.
Earliest drilling was successful testing of
geochemical and/or geophysical
anomalism adjacent to historic small
mining. This progressed into drilling on grid
sections to test the discovered
mineralisation at intervals appropriate for
good confidence in continuity. The earliest
was diamond drilling by Amax commencing
25 October, 1971. The Longyear 44 rig
used was top industry standard for the

 Similarly, the first single shotgyro
instrumentswere being used for downhole
surveys. Handheld GPS became practical
for sub-5m accuracy collar positioning in
year 2000 (removal of Selective
Availability). The most recent programs
after and including 2004 used Trimble GPS
for collar positioning. The first hole to have
(Differential) GPS collar positioning was
TLPD-55 which commenced 3 Nov1995.
About 40 percent of the total metreage
drilled was GPS located.
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).
 HQ and NQ core, recoveries recorded,
sampling by half core predominantly, focus
for historic cut selection mainly dependent
upon visible base metal sulphide-bearing
drill core.
 Two main types of drilling have been used
since the first drill testing at Lewis Ponds in
1971:
 Reverse Circulation Percussion (RCP) and
Diamond Core Drilling (DD). Open hole
techniques including Tricone, Blade and
Hammer have been used to pre-collar holes
through overburden and barren ground to
place casing to facilitate deeper RC and/or
DD.
 Prior to 1980, HQ core size was used only
to seat the casing to enable NQ coring to
start. Most of these holes at some stage
reduced to BQ core size when rotation
became an issue with NQ. In DD programs
subsequent to 1980 HQ core size was used
to refusal then reduction to NQ and possibly
BQ. After 1990 triple tube barrels were
used to good effect minimising core loss,
and reduction to NQ became the norm with
no further use of BQ coring.
 Diamond tails, as distinct from pre-collars,
were used to extend RCP holes in the 2004
programs. These totalled 152 m in five
holes.
 No use of oriented core was made until
2004 where drillers marks on core assisted

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.
 Core recoveries at Lewis Ponds have not in
every case been recorded on a sample by
sample basis, however a good recovery
database is provided by recoveries
recorded in the Geological Logs. These
logs show that significant core loss is a
comparatively rare event once the hole
enters competent rock, and in most cases
is due to local faulting and/or shearing.
Recovery of core has been measured by
restoring the core, fitting individual pieces
end to end where possible. Lengths of the
assembled core were measured to
compare with the intervals between drillers’
downhole markers. The ratio between the
measured length andthemarker interval
length was recorded as core recovery
percent. Percussion chip samples, at least
in the more recent RC drilling, were
weighed and the weight recorded. Any
noticeably low weight recorded became a
recovery factor in the sampling record.
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.
 Logging of core and chips has been
maintained throughout the Lewis Ponds
programs. In the 1992 - 2004 programs,
logs of downhole geology were generally
prepared on paper proformas then entered
digitally. In most cases scans of the hand
logs have been made as well as the digital
logs.
 The first objective has been to enable the
lithology, alteration and mineralisation, and
oxidation records to appear on screen
together with grades for geological
interpretive purposes. This has taken place
to the standard required for mineral
resource estimation and subsequent
studies. The geological logging done,
together with available photography, is
considered to be adequate for mineral
resource studies.
 Where needed terms such as ‘massive’,
semi-massive’ ‘stringer’ or ‘disseminated’
have been used to describe the aspect of
the metal sulphides. These qualitative
terms are expected to be reflected in the
assay results for the same intervals. This
applies to logging both core and chips.
Visual estimation of sulphide percentages

 Core photography has been carried out
over the mineralised intervals in core
obtained between TLPD33 and TLPD72
(Oct 1994 to April 1997) and the
mineralised section of TLPD12. This
represents approximately 50% of the total
drilling, thus there is insufficient core
photography to be a proxy for geotechnical
logging in the event of a scoping study for
Lewis Ponds.
 Minimal geotechnical logging, due to lack
of orientated drill core.

•Measures taken to ensure that the sampling
is representative of the in-situ material

•Whether sample sizes are appropriate to
the grain size of the material being sampled.
 Insufficient detail in pre-1992 historic
reports, reputable international explorer
using standard industry practice of the
time.
 With both RCP and DD drill sampling, a
replicate sample was taken every 20m for
quality control and submitted without
special identification with other samples to
the laboratory. It was rare for replicate
sample assays, when compared with the
original, to fall outside normal variability
within the sampling/assay process. On
some occasions a triplicate sample was
taken for an umpire Au assay.
 The Lewis Ponds sulphides, whether
massive, stringer or disseminated, have not
raised problems of representivity with the
RCP and DD sampling employed.
 Gold is a significant element of the Lewis
Ponds metal value and could have
representivity issues. Preliminary
metallurgical study indicates that gold is
largely refractory within sulphides.
“Nugget” gold is therefore unlikely to be a
problem in fresh rock at Lewis Ponds with
attendant representivity issues. This may
have to be reviewed if mineralisation in the
oxide zone becomes a drilling target.

holes have been picked up using a DGPS
Sub-1 metre instrument since mid-1995.
Prior to that, holes may have been sited
relative to a pegged tape and compass grid
with significant inaccuracies. However in
1995 all previous hole collars appear to
have been identified and surveyed by
DGPS. No tape and compass coordinates
are used to locate any item of drill data in
the current database. In 2004 limited
checks were made of surviving early hole
collars (pre-1995) using DGPS with
satisfactory results when compared with

simple lenses at all downhole Zinc
Equivalent (ZnEq) cut-offs up to 8 to 9 %
ZnEq.
 Cross sections are 20 m apart. On any one
cross section three or more drill holes are
sufficient to characterise the lenses. The
drill intersections are usually about 50 to
80m apart down dip.
 For the thickest part of the Main Lenses
this criterion applies on six contiguous
cross sections, that is 120m of strike
length. From this base, at the low 1% ZnEq
cut-off, one or two intersections per cross
section are sufficient to carry the lens
interpretation a further 40m north and
300m up plunge to the south. At this point
there is a second interval of 100m strike
length near surface with 3 intercepts per
cross section. At the plus 7% ZnEq cut-off,
the lenses are limited to the 120m interval.
It is considered that this data distribution
permits estimation of resources in the
Indicated category.
 For the Exploration Target Stringer
interpretations, Lens interpretation has
used Grade Composites based on (a) a
1% ZnEq downhole cut-off, effectively
quantifying stringer and disseminated
mineralisation, and (b) a 7% ZnEq
downhole cut-off characterising semi-
massive and massive sulphide
mineralisation.

abandoned after entering disused workings
at the Spicers Mine location, Lewis Ponds.
 Subsequent drilling by Aquitaine Australia
Minerals Pty Ltd in 1975-1976 was under
joint venture agreement with Amax and
Shell Company of Australia. 10 (BOA
series) holes were drilled totalling 2102
metres, which also contributed four
intercepts.
 Between 1979 and 1981 a further 7 holes
totalling 2274 metres (SLP series) were
drilled by Shell and Aquitaine under the JV
agreement with Amax. This drilling
contributed five intercepts including one
twinned in a wedge hole.
 In total, other party exploration contributed
15 percent of the database which now
determines the geometry of potentially ore
grade mineralisation for this Resource
estimate.
 In 1987-1988, the Homestake subsidiary
Sabminco drilled 33 RCP holes totalling
2300 metres (LPRC series). This drilling
contributed 21 intercepts of the 230 used to
interpret the Resource.
 Prior to the acquisition of TriAusMin by
Heron in August 2014, Tri Origin Australia
drilled 42,232 metres in 124 holes, followed
by Tri Origin Minerals with 3,812 metres in
30 holes.

Data
aggregation
methods
• 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.
Massive mineralization model:
 Grade compositing was by averages above
cutoff weighted for sample length. The
maximum total inclusion of subgrade was
5m and the maximum consecutive inclusion
of subgrade was 3m.
 Two sets of composites were prepared, one
based on downhole cut-off of 1 percent Zinc
Equivalent (% ZnEq) and the other based on
7% ZnEq (potentially economic). No cutting
of high grades took place at the aggregation
stage because grade composites were used
only for the interpretation of the geometry of
the mineralisation on cross section and in
plan, prior to wireframing, not for Resource
estimation.
Stringer Exploration Target mineralization
model:
 There was no limitation on internal waste,
since the objective was to generate mining
shapes for a low grade open-pit bulk mining
operation.
 The historic Lewis Ponds core assay data
has significant runs of unassayed material
which has been included in intercept runs as
nil grade. Review of available core
photography and geological logs confirms a
significant proportion of un-assayed internal
waste is sericite-pyrite altered and thus
prospective for “orogenic gold”.
Relationship
between

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 (eg ‘down hole length,
true width not known’).

require geo-metallurgical assessment.

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
