Ardea Resources Limited (ASX: ARL, “Ardea” or “the Company”) is pleased to announce extensive broad scale intercepts of base- and precious-metal mineralisation (e.g. Figure 1) from the first two drillholes at Lewis Ponds in NSW.

The successful identification of this gold, silver, zinc and lead mineralisation confirms the Company’s hypothesis that the Lewis Ponds deposit is more like the major deposits of the Lachlan Fold Belt region (in terms of its bulk tonnage potential) than has been previously recognised.

Results are presented for the first two diamond drill holes drilled by Ardea at Lewis Ponds in March 2017.

Geology and mineralisation

Lewis Ponds is a zinc-gold-silver(-lead-copper) deposit in the Lachlan Fold Belt of NSW (Figure 2). The belt is host to numerous major bulk tonnage gold and base metal mines. Of particular note is that the major deposits at Northparkes and Cadia are hosted within or adjacent to the Lachlan Transverse Zone (LTZ), a west-northwest trending lineament that is thought to represent a fundamental crustal weakness that corresponds to major mineralisation. Several of Ardea’s projects, including notably Lewis Ponds, are located within the LTZ.

Drill holes ALD0001 and ALD0002 (Table 1) are the northern two holes of the recent drill program aimed at generating material for Lewis Ponds metallurgical test-work. These holes filled gaps in the distribution of the extensive historic drilling and were designed primarily to provide material for metallurgical testwork as well as generate data in gaps in the database. They will also be used to answer questions regarding controls on the mineralisation, distribution of gold and silver relative to the base metals, and the extent and distributions of low-grade mineralisation relative to the higher-grade (deeper set) mineralisation that has been the focus during previous exploration efforts. Additionally, Ardea has interpreted that the shallow higher grade portions of the mineralisation may have a supergene sulphide component, which will require specific metallurgical assessment.

Figure 2 – Map of Ardea’s projects in the Lachlan Fold Belt of NSW. Lewis Ponds is, like many of the region’s major deposits, located in the highly prospective Lachlan Transverse Zone.

Visible mineralisation has previously been reported to comprise sphalerite, pyrite, galena, pyrrhotite, and trace chalcopyrite. Gold and silver have not been observed in hand specimen. The host rock sequence comprises a marine sequence of felsic to intermediate sediment-facies volcaniclastic rocks.

The sequence has been metamorphosed to around lower greenschist facies, and deformation is pervasive, varying from mild to strong and has clearly influenced mineralisation.

A series of intercepts have been calculated for Ardea’s first two drill holes at Lewis Ponds. By using a cutoff of 1.5% zinc equivalent, mineralised intercepts have been defined of a broad style anticipated by Ardea and that are typical of the major deposits of the Lachlan Fold Belt of NSW.

The listing of assays for all samples received from Ardea’s first two drillholes at Lewis Ponds is presented in Appendix 3.

Mineralisation in ALD0001

In ALD0001, two broad mineralised “Polymetallic Stringer” sphalerite-pyrite zones which are separated and surrounded by disseminated low grade mineralisation were intersected:

  • 51.37 m at 2.45 % Zn equivalent or 1.48 g/t Au equivalent (1.28 % Zn, 0.18 g/t Au, 22.0 g/t Ag, 0.51 % Pb, and 0.11 % Cu) from 41.60 m

  • 20.91 m at 2.74 % Zn equivalent or 1.63 g/t Au equivalent (1.39 % Zn, 0.17 g/t Au, 32.7 g/t Ag, 0.56 % Pb, and 0.10 % Cu) from 110.76 m

==> picture [498 x 384] intentionally omitted <==

Figure 4 – Cross section along the 11000mN line on the Lewis Ponds grid, showing interpreted mineralisation distributions.

These two intercepts combined with the lesser mineralised zone between them cover a downhole thickness of 104.25 m. Over this thickness, the interstitial and mineralised zones show a distinct geochemical signature that comprises elevated zinc (>0.3 %), gold (>0.2 g/t), silver (>15 g/t), antimony (>30 ppm), and manganese (>800 ppm), and depleted barium (<200 ppm) compared to non-mineralised zones. Using these criteria, a strong Polymetallic Stringer mineralised sequence is evident that encases the above intercepts within a broad zone measuring:

  • 104.25 m at 1.94 % Zn equivalent or 1.15 g/t Au equivalent (1.01 % Zn, 0.13 g/t Au, 19.5 g/t Ag, 0.40 % Pb, and 0.08 % Cu) from 41.60 m.

This zone is geologically and geochemically coherent, and corresponds to strong chlorite-pyrite alteration, whereas sericite-dominant alteration occurs outside the Stringer zone. Common chloritic shear zones,

==> picture [174 x 23] intentionally omitted <==

white quartz veining and solution brecciation of carbonate horizons are consistent with a high strain environment conducive to fluid movement.

Mineralisation in ALD0002

In ALD0002, a single higher-grade zone comprised of Polymetallic Stringer sphalerite-pyrite mineralisation shows an abrupt contact with the surrounding rock types.

  • 16.40 m at 8.53 % Zn equivalent or 5.07 g/t Au equivalent (4.73 % Zn, 0.86 g/t Au, 75.9 g/t Ag, 1.44 % Pb, and 0.19 % Cu) from 43.60 m

In addition, this intercept is underlain by the footwall dolomite unit, and the hangingwall volcaniclastics are oxidised due to proximity to surface. It is likely that the intercept in ALD0002 is the basal portion of the mineralised zone that is more completely preserved in ALD0001. The ALD0002 mineralisation likely has a supergene sulphide component.

Core hole ALD0002 has twinned historic reverse circulation drill hole LPRC0016. Comparison results are acceptable, with LPRC0016 intersecting 16 m at 4.42 % Zn equivalent or 2.71 g/t Au equivalent (2.05 % Zn, 0.79 g/t Au, 74.0 g/t Ag, no historic assays for Pb or Cu) from 34 m. The historic RC drilling would appear to have underestimated zinc grade.

Similarities with the major deposits of the region

Previously, Lewis Ponds has been explored as a high-grade underground deposit, with a historic resource of 6.6Mt at 1.5g/t Au, 69g/t Ag and 2.4% Zn[3] estimated at a 3% ZnEq cut-off grade (refer Prospectus Table 3.2 for full description of resource status).

The published Lewis Ponds resource of 6.6 million tonnes (refer below) as a potential underground operation was calculated at a 3% zinc equivalent cut-off (as opposed to Ardea’s 1.5% zinc equivalent cutoff) for an envisaged open pit mining operation. The Ardea concept is consistent with bulk tonnage operations in the central Lachlan Fold Belt (LFB) which are all low grade, bulk excavation-based (Table 2). Both Cadia and Northparkes produce sulphide concentrates with precious metal credits, whereas Cowal and the undeveloped McPhillamys deposit utilise (or propose to utilise) a carbon-in-leach (CIL) flowsheet. In terms of metal value (i.e. zinc and gold equivalent values), the mineralised zones intercepted in ALD0001 and ALD0002 match or exceed those of the major Lachlan Fold Belt operations (Table 2).

These results justify Ardea’s updated Exploration Target for the Lewis Ponds deposit, estimated at 15–25 Mt at 2.2–3.7 % ZnEq or 1.2–2.0 g/t AuEq[4] (Heron Resources announcement, “Ardea Project Update” dated 6 January 2017).

4 Details of the Exploration Target were described in full in the announcement by Heron Resources dated 6 January 2017. 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. For this previously published Exploration Target, Zn equivalents were defined using the following values (21/12/2016 US$ price, recovery): Zn ($2617/t, 100%), Au ($1133/oz, 90%), Ag ($16.00, 80%), Pb ($2259/t, 80%), Cu ($5488.5/t, 80%). Zn equiv. = Zn(%) + 1.253Au(g/t) + 0.016Ag(g/t) + 0.665Pb(%) + 1.678Cu(%). Values used for zinc equivalent calculations throughout this announcement (except for the previously announced Exploration Target). Zinc equivalents used as zinc contributes most to the metal equivalent calculations. Au equivalents were defined using the following values (21/12/2016 US$ price, recovery): Zn ($2617/t, 80%), Au ($1133/oz, 100%), Ag ($16.00, 80%), Pb ($2177/t, 80%), Cu ($5488.5/t, 80%). Au equiv. = 0.575Zn(%) + Au(g/t) + 0.016Ag(g/t) + 0.478Pb(%) + 1.205Cu(%). Gold equivalents used for direct comparison to major deposits of the region. Scoping study level financial model for a 1.5Mtpa open-pit with base metal float circuit indicates 1.6% ZnEq is a suitable break-even cut-off grade.

Results for the remaining two drillholes at Lewis Ponds are expected shortly. Ardea looks forward to updating shareholders once results are received. Additionally, results for the oxidised portions of ALD0001 and 0002 are awaited.

Pre-feasibility study

A study manager has been appointed for Ardea’s Lewis Ponds Pre-feasibility Study and a metallurgical laboratory retained.

Once results for all four holes drilled to date are available, the core will be composited into “run-of-mine” grade bulk samples for metallurgical testwork.

Appendix 1 – JORC Code, 2012 Edition, Table 1 report

Section 1 Sampling Techniques and Data

(Criteria in this section applies to all succeeding sections)

Criteria JORC Code explanation Commentary
Sampling
techniques
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.
• Samples from the diamond-core holes are being taken from mostly HQ3 and NQ3 sized core and
sampled on a nominal 1 metre basis taking into account smaller sample intervals up to geological
contacts. The core is cut in half along the core orientation line (where available) and in massive
sulphide zones one portion is quartered for assaying, half the core is preserved for metallurgical
testing and the remaining quarter is retained as reference material in the core trays. In non-
massive sulphide material half core is sampled.
• These sampling methods are standard industry methods and are believed to provide acceptably
representative samples for the type of mineralisation encountered.
Drilling
techniques
Drill type (eg core, reverse circulation, open-hole hammer, rotary air
blast, auger, Bangka, sonic, etc) and details.
• Diamond-core drilling was undertaken by a Sandvik DE710 rig with mostly NQ3 sized core being
drilled. Various techniques are employed to ensure the hole is kept within limits of the planned
position. The core is laid out in standard plastic cores trays.
Drill sample
recovery
Method of recording and assessing core and chip sample recoveries
and results assessed.
• The core is transported to an enclosed core logging area and recoveries are recorded.
Recoveries to date have been better than 95%. The core is orientated where possible and
marked with 1 metre downhole intervals for logging and sampling.
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.
• The diamond core is geologically logged by qualified geologists. Geotechnical logging is also
being undertaken on selected sections of the core. Samples for metallurgical testing are being
kept in a freezer to reduce oxidation prior to being transported to the metallurgical laboratory.
Sub-sampling
techniques and
sample
preparation
For all sample types, the nature, quality and appropriateness of the
sample preparation technique.
• All core and rock chip samples are crushed then pulverised in a ring pulveriser (LM5) to a nominal
90% passing 75 micron. An approximately 250g pulp sub-sample is taken from the large sample
and residual material stored.
• A quartz flush (approximately 0.5 kilogram of white, medium-grained sand) is put through the LM5
pulveriser prior to each new batch of samples. A number of quartz flushes are also put through
the pulveriser after each massive sulphide sample to ensure the bowl is clean prior to the next
sample being processed. A selection of this pulverised quartz flush material is then analysed and
reported by the lab to gauge the potential level of contamination that may be carried through from
one sample to the next.

Criteria JORC Code explanation Commentary
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.
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.

Sample preparation and assaying is being conducted through ALS Laboratories, Orange, NSW
with certain final analysis of pulps being undertaken at the ALS Laboratory in Brisbane QLD.

Gold is determined by 30g fire assay fusion with ICP-AES analysis to 1ppb LLD.

Other elements by mixed acid digestion followed by ICP-AES analysis.

Laboratory quality control standards (blanks, standards and duplicates) are inserted at a rate of 5
per 35 samples for ICP work.
Verification of
sampling and
assaying
The verification of significant intersections by either independent or
alternative company personnel.
Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic) protocols.
Discuss any adjustment to assay data.
• An internal review of results was undertaken by Company personnel. No independent verification
was undertaken at this stage.
• All field and laboratory data has been entered into an industry standard database using a contract
database administrator (DBA) in the Company’s Perth office. Validation of both the field and
laboratory data is undertaken prior to final acceptance and reporting of the data.
• Quality control samples from both the Company and the Laboratory are assessed by the DBA and
reported to the Company geologists for verification. All assay data must pass this data verification
and quality control process before being reported.
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 Resource estimation.
• The drill collars were initially located with a combination of handheld GPS and licenced surveyor
using a DGPS system, with accuracy of about 1m. The final drill collars are “picked up” by a
licenced surveyor with accuracy to 1 centimetre.
• While drilling is being undertaken, downhole surveys are conducted using a downhole survey tool
that records the magnetic azimuth and dip of the hole. These recordings are taken approximately
every 30 metres downhole. Where possible holes are also being surveyed with gyroscopic
methods, with some 80 percent of holes drilled in the current program also surveyed by this
method after drilling has been completed.
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.
• The diamond drilling is mostly following-up in various directions from previous intercepts with a
nominal spacing in the range 50-100m. This drill hole spacing will be sufficient to provide Mineral
Resource estimates in the future.
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.
• The drilling orientation is designed to intersect the mineralised lenses at a close to perpendicular
angle. The mineralised lenses are dipping at approximately 50-60 degrees to the northeast and
the drilling is approximately at 60 degrees to the southwest. This will vary from hole to hole.
Sample security The measures taken to ensure sample security. • Samples are being secured in green plastic bags and are being transported to the ALS laboratory
in Orange, NSW via a courier service or with Company personnel/contractors.

Exploration
done by other
parties
Acknowledgment and appraisal of exploration by other parties. • The Lewis Ponds deposit and surrounding workings were part of Australia’s first recognised gold
field, discovered 1835. Various surface and shallow underground mining operations and
associated processing and smelting operations were present at various times between discovery
and approximately 1920. The detailed history for this period is presently the subject of research.
• Amax Exploration Australia Inc entered a Joint Venture Agreement which Metals Investments
Holdings NL and A.I.Consolidated Gold Pty Ltd held with the owner of the title ,Wentworth Mining
Corporation Pty Ltd, over ground which included the Lewis Ponds deposit. Amax drilled four DD
holes totalling 875 meters in 1971-1972 which contributed four intercepts above 7% ZnE to this
Resource estimate. The only drilling done prior to Amax was by Cominco in 1969. Three holes
were 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, theHomestake subsidiary Sabminco drilled 33RCP holes totalling2300metres

(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 42232
metres in 124 holes, followed by Tri Origin Minerals with 3812 metres in 30 holes.
Geology Deposit type, geological setting and style of mineralization. • The most recent statement of the Lewis Ponds geology by Dr Peter Gregory (2005) has also built
on much prior geological insight by other parties in the 1970s and 1980s, and by geologists
employed by predecessor companies to Tri Origin Minerals since 1992. Also between 1999 and
2003 a comprehensive Ph.D study of the geology was made (Agnew 2003) A re-cast of Peter
Gregory’s summary is as follows:
• Type: Results of the study show that primary volcanogenic mineralisation of Late Silurian age
developed within an extensive axial zone over 1200m in a moderately deep water trough
(extensional back arc). Mineralisation deposited at one horizon close to and possibly on the
seafloor within sediments and volcaniclastics and at the end of a rhyolite-dacite volcanic episode
involving lava domes. Tom’s Zone in the south formed in a quieter sedimentary environment
dominated by siltstones. Current work by Ardea is showing that late-stage gold mineralization
overprints the earlier VMS style mineralsation.
• Setting: The Lewis Ponds mineralised zone is located on the eastern limb of a major regional F1
anticline and within several subsidiary anticlinal and synformal zones on that limb. Plunges are
variable with Main Zone plunging moderately northwest, but there appears to be little or no plunge
along other sections of the mineralised trend. Various reverse faults probably emanating from a
basal sole thrust at the contact of the Ordovician basement and the Silurian rift succession cut the
axial zones of several of these folds and leave most volcanic sediment contacts as fault zones.
The Lewis Ponds Fault, a ductile and brittle fault zone cuts a synform axis and has caused, kinking
and reorientation of cleavage and remobilisation of sulphides. An interpreted southwest-northeast
dip slip fault near 1220N is suggested to downfault the mineralised package to the northwest
• Style of mineralisation: Main Zone mineralisation to the north is largely composed of massive to
semi-massive sulphide replacement as well as veining and dissemination within the host polymict
breccia-volcaniclastic-siltstone package. Mineralising fluids emanating from syn-volcanic faults in
the footwall porphyry moved laterally through porous zones in the host package causing sulphide
replacement. The mineralising fluids may have exhaled on the seafloor at some stage based on
the minor occurrence of interpreted reworked sulphide clasts and interstitial bands of fine sulphide
in some carbonate dominated breccias. Tom’s Zone in the south consists of a narrow massive
sulphide stratiform zone in reasonable proximity to interpreted footwall feeder pyrite-chalcopyrite
stringers. Subsequent, possibly epithermal style precious metal mineralisation is present though
its relationship to the earlier, well-documented mineralisation is not yet clear.

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.
• No grade aggregation methods were used for this announcement. For treatment of historical data,
see below.
• Grades: 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 cutoff of 1 percent Zinc
Equivalent (% ZnE) and the other based on 7% ZnE (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.
• Metal Equivalent: Being a multi-element deposit in terms of value, some synthesis of the
contribution of five metals, Au, Ag, Cu, Pb and Zn to the application of any downhole (or block)
cutoff was required. The standard technique of converting grade to $US per grade unit (gram,
ounce, percent), adding the dollar contributions then converting back to a single metal equivalent
was used, in this case Zn Equivalent percent. Conversion to Au equivalent grams per tonne would
have served the same purpose.
• For 2016 purposes the question arises: would the use of current metal prices make an appreciable
change to the estimated Resource figure via changes to the intercept lengths used to define the
geometry of the mineralised lenses? Re-calculation of the project’s zinc equivalents and
comparison with the 2005 figures give interesting results for intercepts above the 7% ZnE cutoff:
the number of intercepts increases by 20 percent (although many lie between 7 and 8% ZnE); the
sum of intercept lengths increases 30 percent and the weighted average ZnE grade of intercepts
increases marginally, about 7 percent. Much of this lift is carried by the higher Au intercepts, the
gold price having increased 300% since 2005. These changes in ZnE suggests that if the same
cutoffs are retained (1% and 7% ZnE), a somewhat larger mineralisation could be interpreted at a
similar grade. For the purposes of this report it is sufficient to say that there is no ZnE penalty in
respect of today’s metal prices.
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.
• Within the Main zone the strongest mineralisation dips about 50° northeast with vertical tails up to
the west and down to the east, ie sigmoid. This has resulted in intersection angles effectively
normal to the thicker parts of the mineralisation making true widths equal to downhole widths.
Where the lens tails up to the west and down to the east, the angles reduce to 40° to 60° with
much reduced true widths in the thinnest parts of the mineralised lenses.
• In Toms zone to the south of Main zone, dips of mineralisation are vertical or sub-vertical. In the
upper levels, angles between hole and mineralisation are around 50° but at deeper levels can be
as low as 30° or 20°, substantially reducing true widths. Interpretation of mineralised lenses
honours the true widths.

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 drilling to show at this stage. Do be drafted for future releases.
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
Results.
• The reporting is considered to be balanced and all relevant results have been disclosed for this
current phase of exploration.
Other
substantive
exploration data
Other exploration data, if meaningful and material, should be reported
including (but not limited to): geological observations; geophysical
survey results; geochemical survey results; bulk samples – size and
method of treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics; potential
deleterious or contaminating substances.
• The most material information affecting the resource estimates was the geological logging and
core photography carried out by Dr Peter Gregory (Gregory, P., February 2004 and Gregory P.,
January 2005). This work was completed in time for this estimate (April 2005). Of particular
interest were his views on the likely continuity of the massive sulphides as distinct from the
enclosing dissemination, veins and stringers, especially as the highest grades are identified with
massive or ‘semi-massive’ sulphides. A number of geologists, including Gregory, are of the
opinion that mass flows incorporating carbonate and volcanic debris have disrupted earlier
seafloor-deposited massive banded sulphides. This happened in situ without significant transport
away from the original depositional site. Thus at say a 1% ZnE cutoff, the mineralisation has good
continuity. At a higher cutoff, say 7% ZnE continuity could become an issue. With a drill spacing
sometimes 50-100m there is every possibility of a massive sulphide ‘bed’ being disrupted into a
series of “rafts” generally parallel to the axis of the +1% mineralisation.. However, in seeking to
model the deposit, statistically massive sulphide seems to be represented in adjacent holes as
though it were a continuous or semi-continuous bed.
• A number of metallurgical studies have now been made of Lewis Ponds mineralisation. These
have centred on optimising the number of concentrates, predicting what percentage of the gold
could report to a gravity circuit and whether refractory gold should go to CIL or be paid in the
concentrates. These studies have been reviewed by R W Nice (2006).
Further work The nature and scale of planned further work (eg tests for lateral
extensions or depth extensions or large-scale step-out drilling).
• In the 11 years since this estimate was prepared Au and Ag metal prices have trebled and Cu, Pb
and Zn effectively doubled. To test the effect, zinc equivalents for Lewis Ponds have been re-
calculated using metal prices current at 1 September 2016. Any intercepts with significant Au
have increased 30 to 50 percent in terms of ZnE and a significant number which were near below
the 7 percent ZnE cutoff are now above the cutoff. The result has been a 20 percent increase in
the number of intercepts, a 30 percent increase in the total intercept metreage, and a 6 percent
increase in the average dollar value of the intercepts. Thus there could be case at some stage to
re-model the geometry of the lenses and to re-estimate a block model.
• Also the LPRC34-LPRC41 drilling done in 2011, which had some intersections of interest, with
further comparatively short hole drilling, approximately 100m each, could add a useful tonnage
and value to the Resource. The structure drilled is on the Torpy’s Shaft line and is open south.
