Newcrest Reports Further Drilling Results at Havieron
Latest excellent infill drilling results confirm continuity of higher-grade
mineralisation
2021 growth drilling programme: approximately 65,000 metres in next six months
to test potential extensions to resource shell, new targets identified
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and
development company, is pleased to provide an update on Newcrest's drilling
campaign at the Havieron deposit in the Paterson region of Western Australia.
The Company notes the release of an ASX announcement titled "Quarterly
Exploration Report" by Newcrest Mining Ltd ("Newcrest") earlier today.
Drilling since May 2019 has outlined an ovoid shaped zone of variable
brecciation, alteration and sulphide mineralisation with dimensions of 650m x
350m trending in a north west orientation. Breccia mineralisation has been
identified internally and externally to the Crescent Zone, including targets
which remain open to the east, northwest and southeast. Mineralisation has
been observed to over 1,000m in vertical extent below the post mineralisation
cover sequence and remains open at depth.
During the last quarter of calendar 2020, drilling activities at Havieron
primarily focused on ongoing infill drilling of the South East Crescent and
Breccia Zone. This infill drilling was conducted to support the potential
delivery of an Indicated Mineral Resource in the South East Crescent Zone and
adjacent Breccia Zones. Assay results for a total of 18 new drill holes have
been received since the last update (10 December 2020) and are reported here
today.
Highlights
· Further Excellent Results from Infill Drilling: Latest drill
results confirm the continuity of higher-grade mineralisation within the South
East Crescent and Breccia. Mineralisation is open at depth below the Inferred
Mineral Resource shell providing support for potential expansion at depth.
· 2021 Growth Drilling Programme: The 2021 growth drilling
programme includes plans for approximately 65,000 metres of drilling within
the next six months and will focus on the following targets:
· South East Crescent and Breccia: Potential resource definition of
extensions below the existing resource shell and lateral extensions adjacent
to the existing high grade resource shell.
· Northern Breccia: Potential expansion of the existing Inferred
Mineral Resource below and adjacent to the existing resource shell.
· Eastern Breccia: Drill testing and interpretation of the
geological and mineralisation controls of the Eastern Breccia Zone is ongoing.
· New Targets: New targets outside of the immediate vicinity of the
Havieron deposit, but within the Havieron Joint Venture area, have been
identified with the potential to conduct drill testing of these targets in the
future.
· Early Works Underway: As announced on 21 January 2021, earth
moving activities to prepare for the construction of the box cut and decline
have commenced, and work continues to investigate the potential to achieve
commercial production at Havieron within three years of the commencement of
the decline.

Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "As
earth moving activities commence at Havieron, Newcrest continues to deliver
excellent infill results within the existing resource shell and is launching
an exciting 2021 growth drilling programme with the potential to further
expand the mineralised footprint. The latest drill results increase our
confidence in the continuity of higher-grade mineralisation and support the
potential delivery of an Indicated Mineral Resource. Meanwhile, Newcrest's
plans for 65,000 metres of growth drilling will target several zones which
could represent potential extensions to mineralisation outside of the Inferred
Mineral Resource estimate, as well as new targets announced today within the
Havieron joint venture area.
"Alongside the ramp-up of exploration and early works activities at Havieron,
we are also preparing to launch our Juri Joint Venture exploration programme
for 2021, which will focus on drill testing priority targets, including the
Parlay target within the Black Hills Project and the Goliath, Outamind and Los
Diablos targets within the Paterson Range East Project. We look forward to
providing regular updates on activities at both joint ventures - Havieron and
Juri - in due course."

Further Information on Newcrest Drilling and Operations at Havieron
Exploration activities at Havieron are operated by Newcrest under a Joint
Venture Agreement with Greatland. The Havieron deposit is centered on a
magnetic anomaly located 45km east of Telfer. Exploration drilling by
Greatland during 2018 resulted in the discovery of significant gold and copper
mineralisation under 400m of post mineralisation cover. Newcrest commenced
drilling at Havieron during the June 2019 quarter and have completed 138,504m
of drilling from 153 holes to date.
Drilling activity has progressively increased such that up to nine drill rigs
were in operation during the quarter to 31 December 2020. Results reported
today include 18 new drill holes (completed since the last release dated 10
December 2020) and relate to infill drilling of the South East Crescent and
Breccia Zone. This infill drilling is to support the potential delivery of an
Indicated Mineral Resource and associated studies. All new drill holes
intersected mineralisation. Significant new results are presented in Table 1.
The infill drilling results announced today are considered excellent.
Drilling since May 2019 has outlined an ovoid shaped zone of variable
brecciation, alteration and sulphide mineralisation with dimensions of 650m x
350m trending in a north west orientation. Breccia mineralisation has been
identified internally and externally to the Crescent zone, including targets
which remain open to the east, northwest and southeast. Mineralisation has
been observed to greater than 1000m in vertical extent below the post mineral
cover sequence and remains open at depth. Within this ovoid shaped zone (at
this stage) exploration has identified four key target regions, which are:
· South East Crescent and Breccia
· North West Crescent
· Northern Breccia
· Eastern Breccia
Drill data density in the South East Crescent and adjacent Breccia and a
portion of the Northern Breccia has been sufficient for the definition of an
Inferred Mineral Resource Estimate(2) for these domains. Reported inside an
A$50/t Net Smelter Royalty ("NSR") shell, the volume of identified mineralised
geological domains where information to estimate the metal inventory and
grades is at a sufficient magnitude and having the reasonable prospects of
eventual economic extraction comprises:
· 52Mt @ 2.0g/t Au and 0.31% Cu for 3.4Moz Au and 160Kt Cu for 4.2Moz
gold equivalent(3), included in geological domains:
o Crescent Zone containing 18Mt @ 3.8g/t Au and 0.61% Cu for 2.2Moz Au and
110Kt Cu; and
o Breccia Zone containing 34Mt @ 1.1g/t Au and 0.15% Cu for 1.2Moz Au and
50Kt Cu.
2. Refer to Newcrest announcement titled "Newcrest announces
initial Inferred Mineral Resource estimate for Havieron of 3.4Moz of gold and
160Kt of Copper" dated 10 December 2020 and available on www.asx.com.au under
the code "NCM".
3. The gold equivalent (AuEq) is based on assumed prices of
US$1,400/oz Au and US$3.40/lb Cu, gold recoveries of 94% (Crescent) and 84%
(Breccia), and copper recoveries of 84% (Crescent) and 82% (Breccia), which
equates to a formula of approximately AuEq = Au (g/t) + 1.65 * Cu (%). In
Greatland's opinion all elements (gold and copper) have a reasonable potential
to be recovered and sold.
Outside of the Inferred Mineral Resource estimate, mineralisation remains open
with encouraging results identified from the South East Crescent and Breccia
Zone, Northern Breccia Zone, and the Eastern Breccia Zone.
Within the South East Crescent and Breccia Zones 23 holes have been completed
for the reporting period, including 18 new holes. These drill holes are infill
holes within the Mineral Resource and confirm the continuity of higher grade
mineralisation within the South East Crescent and Breccia Zone, including(1):
· HAD025W1
o 111.7m @ 3.6g/t Au & 0.46% Cu from 804.7m
o Including 40.2m @ 8.4g/t Au & 0.53% Cu from 816.8m
· HAD109

· HAD056W1^^
o 205.8m @ 1.2g/t Au & 0.24% Cu from 598m
· HAD097W2^^
o 119.2m @ 2.7g/t Au & 0.4% Cu from 937.8m
Mineralisation is open at depth below the Inferred Mineral Resource shell
providing support for potential resource expansion at depth.
Further drilling of the Northern Breccia Zone included 10 drill holes during
the reporting period (but no new holes since the 10 December 2020 update).
Mineralisation has been identified in 23 drill holes to date which informed
the Inferred Mineral Resource estimate. Results continue to support the
continuity of mineralisation and demonstrate the opportunity to further expand
the mineralisation footprint in this region. Results include(1):
· HAD101^^
o 92.5m @ 1.9g/t Au & 0.06% Cu from 1296m
· HAD103^^
o 90.6m @ 2.3g/t Au & 0.18% Cu from 776.4m
o Including 2.4m @ 67g/t Au and 0.33% Cu from 822.7m
· HAD105^^
o 298.8m @ 1.2g/t Au & 0.11% Cu from 801.6m
o Including 15.8m @ 3.5g/t Au & 0.22% Cu from 821m
Mineralisation at the Havieron deposit has been identified internally and
externally to the Crescent Zone, including targets which remain open to the
east, northwest and southeast. Mineralisation has been observed to greater
than 1000m in vertical extent below the post mineralisation cover sequence and
remains open at depth. The extents of the Havieron system are still to be
defined.
Approximately 65,000m of growth-related drilling is planned over the next two
quarters. Further drilling of the Northern Breccia Zone is ongoing to support
the potential expansion of the existing Inferred Mineral Resource. Drill
testing and interpretation of the geological and mineralisation controls of
the Eastern Breccia Zone is ongoing. Planned growth drilling will also target
potential resource extensions of the South East Crescent and Breccia below and
adjacent to the existing resource shell. Further targets outside of Havieron,
but within the Havieron Joint Venture area, have been identified with the
potential to conduct drilling to test these targets in the future.
Early studies are ongoing and include mining methods, hydrogeology,
geotechnical, metallurgical, engineering and environmental to support
delivery of a Pre-Feasibility Study in late 2021. Earth moving activities to
prepare for the construction of the box cut and decline have commenced as
announced 21 January 2021. Studies continue to investigate the potential to
achieve commercial production within three years from commencement of the
decline.
Additional drill hole information is presented in Appendix I and tabulated
drill hole intercepts are presented in Appendix II.
Mineralisation in the Havieron deposit is hosted by metasedimentary
(meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks.
Gold and copper mineralisation is hosted in breccia, vein and massive sulphide
replacement styles, typical of intrusion-related and skarn types of
mineralisation. The main sulphide mineral assemblage contains well developed
pyrrhotite-chalcopyrite and pyrite. Alteration assemblages associated with
mineralisation are amphibole-carbonate-biotite-sericite-chlorite. Higher grade
gold zones (+10g/t Au) are often associated with quartz/chalcopyrite-pyrite
veining.
Background to Havieron and Joint Venture Agreement with Newcrest
The Havieron Project is operated by Newcrest under a Joint Venture Agreement
with Greatland. As announced on 30 November 2020, Newcrest has now met the
Stage 3 expenditure requirement (US$45 million) and is entitled to earn an
additional 20% joint venture interest, resulting in an overall joint venture
interest of 60% (Greatland 40%). Newcrest can earn up to a 70% joint venture
interest through total expenditure of US$65 million and the completion of a
series of exploration and development milestones in a four-stage farm-in over
a six year period that commenced in March 2019. Newcrest may acquire an
additional 5% interest at the end of the farm-in period at fair market value.
The Joint Venture Agreement includes tolling principles reflecting the
intention of the parties that, subject to a successful exploration programme
and feasibility study and a positive decision to mine, the resulting joint
venture mineralised material will be processed at Telfer, located 45km west of
Havieron.

adjacent landholdings can be found at: www.greatlandgold.com/paterson
(https://greatlandgold.com/paterson/)
Juri Joint Venture
On 30 November 2020, Greatland and Newcrest entered into the Juri Joint
Venture, which is a farm-in and joint venture agreement with respect to
Greatland's Black Hills and Paterson Range East projects, located within the
Paterson Province approximately 50km from the Telfer operation. The new joint
venture covers an area of approximately 248km(2).
Under the terms of the agreement, Newcrest has been granted an initial 25%
joint venture interest with the potential to earn up to a 75% joint venture
interest through total expenditure of A$20 million over a two stage earn-in,
across a five year period. Greatland will manage the Juri Joint Venture until
the end of calendar year 2021, after which Newcrest has the right to be
appointed as Manager.
Newcrest and Greatland have agreed an exploration programme until the end of
calendar year 2021 which is anticipated to drill test priority targets,
including the Parlay target within the Black Hills Project and the Goliath,
Outamind and Los Diablos targets within the Paterson Range East Project.
Additionally, geophysical work will be conducted in calendar year 2021 to
identify other potential targets within both projects.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed (AIM:GGP) natural
resource exploration and development company with a current focus on precious
and base metals. The Company has six main projects; four situated in Western
Australia and two in Tasmania.
In March 2019, Greatland signed a Farm-in Agreement with Newcrest Operations
Limited, a wholly-owned subsidiary of Newcrest Mining Limited (ASX:NCM), to
explore and develop Greatland's Havieron gold-copper deposit in the Paterson
region of Western Australia. The Havieron Project is operated by Newcrest
under a Joint Venture Agreement with Greatland Gold plc. Newcrest can earn up
to a 70% joint venture interest through total expenditure of US$65 million and
the completion of a series of exploration and development milestones in a
four-stage farm-in over a six year period that commenced in March 2019.
Newcrest may acquire an additional 5% interest at the end of the farm-in
period at fair market value.
The Joint Venture Agreement includes tolling principles reflecting the
intention of the parties that, subject to a successful exploration programme
and feasibility study and a positive decision to mine, the resulting joint
venture mineralised material will be processed at Telfer, located 45km west of
Havieron.
Greatland is seeking to identify large mineral deposits in areas that have not
been subject to extensive exploration previously. It is widely recognised that
the next generation of large deposits will come from such under-explored areas
and Greatland is applying advanced exploration techniques to investigate a
number of carefully selected targets within its focused licence portfolio.
The Company is also actively investigating a range of new opportunities in
precious and strategic metals and will update the market on new opportunities
as and when appropriate.
APPENDIX I
Havieron Project (Greatland Gold plc - Joint Venture Agreement): JORC Table 1
Section 1 Sampling Techniques and Data
Criteria Commentary
Sampling techniques Core samples are obtained from core drilling in Proterozoic basement
lithologies. PQ-HQ and NQ diameter core was drilled on a 6m run. Core was cut
using an automated core-cutter and half core sampled at 1m intervals with
breaks for major geological changes. Sampling intervals range from 0.2 - 1.0m.
Cover sequences were not sampled.
Drilling techniques Permian Paterson Formation cover sequence was drilled using mud rotary
drilling. Depths of cover typically observed to approximately 420m vertically
below surface. Steel casing was emplaced to secure the pre-collar.
Core drilling was advanced from the base of the cover sequence with PQ3, HQ3
and NQ2 diameter coring configuration.
Core from inclined drill holes are oriented on 3m and 6m runs using an
electronic core orientation tool (Reflex ACTIII). At the end of each run, the
bottom of hole position is marked by the driller, which is later transferred
to the whole drill core run length with a bottom of hole reference line.
Drill sample recovery Core recovery is systematically recorded from the commencement of coring to
end of hole, by reconciling against driller's depth blocks in each core tray
with data recorded in the database. Drillers depth blocks provided the depth,
interval of core recovered, and interval of core drilled.
Core recoveries were typically 100%, with isolated zones of lower recovery.
Cover sequence drilling by the mud-rotary drilling did not yield recoverable
samples.
Logging Geological logging recorded qualitative descriptions of lithology, alteration,
mineralisation, veining, and structure (for all core drilled - 19,855m from 33
drillholes, all intersecting mineralisation), including orientation of key
geological features.
Geotechnical measurements were recorded including Rock Quality Designation
(RQD) fracture frequency, solid core recovery and qualitative rock strength
measurements.
Magnetic susceptibility measurements were recorded every metre. The bulk
density of selected drill core intervals was determined at site on whole core
samples.
All geological and geotechnical logging was conducted at the Havieron site.
Digital data logging was captured on diamond drill core intervals only, and
all data validated and stored in an acQuire database.
All drill cores were photographed, prior to cutting and/or sampling the core.
The logging is of sufficient quality to support Mineral Resource estimates.
Sub-sampling techniques and sample preparation Sampling, sample preparation and quality control protocols are considered
appropriate for the material being sampled.
Core was cut and sampled at the Telfer and Havieron core processing facility.
Half core samples were collected in pre-numbered calico bags and grouped in
plastic bags for dispatch to the laboratory. Sample weights typically varied
from 0.5 to 4kg. Sample sizes are considered appropriate for the style of
mineralisation. Drill core samples were freighted by air and road to the
laboratory.
Sample preparation was conducted at the independent ISO17025 accredited
Intertek Laboratory, Perth (Intertek). Samples were dried at 105(o)C, and
crushed to 95% passing 4.75mm, and the split to obtain up to 3kg sub-sample,
which was pulverised (using LM5) to produce a pulped product with the minimum
standard of 95% passing 106μm, the sample and 10 samples either side are
re-ground or re-screened. There are very few instances of <95% passing the
second grind. An assessment of the grind size verses Au grade has shown that
rare mineralised assays are affected by grinding issues.
Duplicate samples were collected from crush and pulp samples at a rate of
1:20. Duplicate results show an acceptable level of variability for the
material sampled and style of mineralisation.
Periodic size checks (1:20) for crush and pulp samples and sample weights are
provided by the laboratory and recorded in the acQuire database.
Quality of assay data and laboratory tests Assaying of drill core samples was conducted at Intertek. All samples were
assayed for 48 elements using a 4-acid digestion followed by ICP-AES/ICP-MS
determination (method 4A/MS907), which is considered to provide a total assay
for copper. Gold analyses were determined by 50g fire assay with AAS finish
(method FA50N/AA), which is considered to provide a total assay for gold.
Sampling and assaying quality control procedures consisted of inclusion of
certified reference material (CRMs), coarse residue and pulp duplicates with
each batch (at least 1:20).
Assays of quality control samples were compared with reference samples in
acQuire database and verified as acceptable prior to use of data from analysed
batches.
Laboratory quality control data, including laboratory standards, blanks,
duplicates, repeats and grind size results are captured in the acQuire
database and assessed for accuracy and precision for recent data.
Extended quality control programs including pulp samples submitted to an
umpire laboratory and combined with more extensive re-submission programs have
been completed.
Analysis of the available quality control sample assay results indicates that
an acceptable level of accuracy and precision has been achieved and the
database contains no analytical data that has been numerically manipulated.
The assaying techniques and quality control protocols used are considered
appropriate for the data to be used for reporting exploration drilling
results.
Verification of sampling and assaying Sampling intervals defined by the geologist are electronically assigned sample
identification numbers prior to core cutting. Corresponding sample numbers
matching pre-labelled calico bags are assigned to each interval.
All sampling and assay information were stored in a secure acQuire database
with restricted access.
Electronically generated sample submission forms providing the sample
identification number accompany each submission to the laboratory. Assay
results from the laboratory with corresponding sample identification are
loaded directly into the acQuire database.
Assessment of reported significant assay intervals was verified by re-logging
of diamond drill core intervals and assessment of high resolution core
photography. The verification of significant intersections has been completed
by Newcrest personnel and Newcrest's Competent Person/Qualified Person. John
McIntyre, Greatland's Competent Person, has reviewed and validated the
significant intersections.
No adjustments are made to assay data, and no twinned holes have been
completed.
There are no currently known drilling, sampling, recovery, or other factors
that could materially affect the accuracy or reliability of the data.
Location of data points Drill collar locations were surveyed using a differential GPS with GNSS with a
stated accuracy of +/- 0.5m for all drill holes reported.
Drill rig alignment was attained using an electronic azimuth aligner. Downhole
survey was collected at 6-12m intervals in the cover sequence, and every 6 to
30m in diamond drill core segments of the drill hole using single shot (Axis
Mining Champ Gyro). The single shot surveys have been validated using
continuous survey to surface (Axis Mining Champ) along with a selection of
drill holes re-surveyed by an external survey contactor using a DeviGyro tool
- confirming sufficient accuracy for downhole spatial recording.
A LIDAR survey was completed over the project area in Nov 2019 which was used
to prepare a DEM / topographic model for the project with a spatial accuracy
of +/- 0.1m vertical and +/- 0.3m horizontal. The topography is generally low
relief to flat, elevation within the dune corridors in ranges between 250-265m
Australian Height Datum (AHD) steepening to the southeast. All collar
coordinates are provided in the Geocentric Datum of Australian (GDA20 Zone
51). All relative depth information is reported in AHD +5000m.
Data spacing and distribution Within the South-East Crescent and Breccia zone drill hole spacing ranges from
50 to 100m, to 50 by 50m within the initial resource extents. Outside the
initial resource boundary drill hole spacing ranges from 50 to 200m in lateral
extent within the breccia zone over an area of ~2km(2). The data spacing is
sufficient to establish the degree of geological and grade continuity.
Significant assay intercepts remain open. Further drilling is required to
determine the extent of currently defined mineralisation. No sample
compositing is applied to samples.
Drilling intersects mineralisation at various angles.
Orientation of data in relation to geological structure Drill holes exploring the extents of the Havieron mineral system intersect
moderately dipping carbonate and siliclastic sedimentary facies, mineralised
breccia and sub-vertical intrusive lithologies. Geological modelling has
been interpreted from historic and Newcrest drill holes.
Variable brecciation, alteration and sulphide mineralisation is observed with
a footprint with dimensions of 650m x 350m trending in a north west
orientation and over 1000m in vertical extent below cover.
The subvertical southeast high grade arcuate crescent sulphide zone has an
average thickness of 20m and has been defined over a strike length of up to
550m, and over 600m in vertical extent below cover.
Drilling direction is oriented to intersect the steeply dipping high-grade
sulphide mineralisation zones at an intersection angle of greater than 40
degrees. The drilled length of reported intersections is typically greater
than true width of mineralisation.
Sample security The security of samples is controlled by tracking samples from drill rig to
database.
Drill core was delivered from the drill rig to the Havieron core yard every
shift. On completion of geological and geotechnical logging, core processing
was completed by Newcrest personnel at the Telfer facility but subsequently
completed at the Havieron facility.
High resolution core photography and cutting of drill core was undertaken at
the Havieron or Telfer core processing facilities.
Samples were freighted in sealed bags by air and road to the Laboratory, and
in the custody of Newcrest representatives. Sample numbers are generated
directly from the database. All samples are collected in pre-numbered calico
bags.
Verification of sample numbers and identification is conducted by the
laboratory on receipt of samples, and sample receipt advise issued to
Newcrest.
Details of all sample movement are recorded in a database table. Dates, Hole
ID sample ranges, and the analytical suite requested are recorded with the
dispatch of samples to analytical services. Any discrepancies logged at the
receipt of samples into the analytical services are validated.
Audits or reviews Internal reviews of core handling, sample preparation and assays laboratories
were conducted on a regular basis by both project personnel and owner
representatives.
In the Competent Person's opinion, the sample preparation, security and
analytical procedures are consistent with current industry standards and are
entirely appropriate and acceptable for the styles of mineralisation
identified and will be appropriate for use in the reporting of exploration
results and Mineral Resource estimates. There are no identified drilling,
sampling or recovery factors that materially impact the adequacy and
reliability of the results of the drilling programme in place at the Havieron
Project.
Section 2 Reporting of Exploration Results
Criteria Commentary
Mineral tenement and land tenure status The Havieron Project is entirely contained within mining tenement M45/1287,
which is jointly owned by Greatland Pty Ltd and Newcrest Operations Limited.
Newcrest has entered into a Joint Venture Agreement (effective 30 November
2020) and Farm-In Agreement (effective 12 March 2019) with Greatland Pty Ltd
and Greatland Gold plc. Newcrest is the manager of the Havieron Project.
Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and
is entitled to earn an additional 20% joint venture interest, resulting in an
overall joint venture interest of 60%. Newcrest has the right to earn up to a
70% interest and acquire a further 5% at fair market value.
Newcrest and the Western Desert Lands Aboriginal Corporation are parties to an
Indigenous Land Use Agreement (ILUA) which relates to the use of native title
land for Newcrest's current operations at Telfer and its activities within a
60-km radius around Telfer and includes its exploration activities at
Havieron. The parties have agreed that the ILUA will apply to any future
development activities by the Joint Venture Participants (Newcrest and
Greatland Gold) at Havieron.
The mining tenement M45/1287 wholly replaces the 12 sub-blocks of exploration
tenement E45/4701 (former exploration tenement on which the Havieron Project
is based) and was granted on 10 September 2020. All obligations with respect
to legislative requirements including minimum expenditure are maintained in
good standing for prior exploration tenement E45/4701.
Exploration done by other parties Newcrest completed six core holes in the vicinity of the Havieron Project from
1991 to 2003. Greatland Gold completed drill targeting and drilling of nine
Reverse Circulation (RC) drill holes with core tails for a total of
approximately 6,800m in 2018. Results of drilling programs conducted by
Greatland Gold have previously been reported on the Greatland Gold website.
Drilling has defined an intrusion-related mineral system with evidence of
breccia and massive sulphide-hosted higher-grade gold-copper mineralisation.
Geology The Havieron Project is located within the north-western exposure of the
Palaeo-Proterozoic to Neoproterozoic Paterson Orogen (formerly Paterson
Province), 45 km east of Telfer. The Yeneena Supergroup hosts the Havieron
prospect and consists of a 9km thick sequence of marine sedimentary rocks and
is entirely overlain by approximately 420m of Phanerozoic sediments of the
Paterson Formation and Quaternary aeolian sediments.
Gold and copper mineralisation at Havieron consist of breccia, vein and
massive sulphide replacement gold and copper mineralisation typical of
intrusion-related and skarn styles of mineralisation. Mineralisation is hosted
by metasedimentary rocks (meta-sandstones, meta-siltstones and meta-carbonate)
and intrusive rocks of an undetermined age. The main mineral assemblage
contains well developed pyrrhotite-chalcopyrite and pyrite sulphide mineral
assemblages as breccia and vein infill, and massive sulphide lenses. The main
mineralisation event is associated with
amphibole-carbonate-biotite-sericite-chlorite wall rock alteration. Drilling
has partially defined the extents of mineralisation which are observed over
650m by 350m within an arcuate shaped mineralised zone, and to depths of up to
1400m below surface.
Drill hole Information As provided in Appendix II.
Data aggregation methods Significant assay intercepts are reported as (A) length-weighted averages
exceeding 1.0g/t Au greater than or equal to 10m, with a maximum of 5m
consecutive internal dilution; and (B) length-weighted averages exceeding
0.2g/t Au for greater than or equal to 20m, with a maximum of 10m consecutive
internal dilution, and (C) intervals of >30g/t with no internal dilution
which are greater or equal to 30 gram metres (Au_ppm x length). No top cuts
are applied to intercept calculations.
Relationship between mineralisation widths and intercept lengths Significant assay intervals reported represent apparent widths. Drilling is
not always perpendicular to the dip of mineralisation and true widths are less
than downhole widths. Estimates of true widths will only be possible when all
results are received, and final geological interpretations have been
completed.

Drillhole Data
Havieron Project, Paterson, Western Australia
Reporting Criteria: Intercepts reported are downhole drill width (not true
width) Au >0.20ppm (0.2g/t Au) and minimum 20m downhole width with maximum
consecutive internal dilution of 10m. Average grades are based on
length-weighting of uncut sample grades. Also highlighted are high grade
intervals of Au >1.0ppm (1g/t Au) and minimum 10m downhole width with
maximum consecutive internal dilution of 5m, and intervals of >30g/t with
no internal dilution which are greater or equal to 30 gram metres (Au_ppm x
length) are tabled. Gold grades are reported to two significant figures, the
downhole lengths are rounded to 0.1m which may cause some apparent
discrepancies in interval widths. Samples are from core drilling which is PQ,
HQ or NQ in diameter. Core is photographed and logged by the geology team
before being cut. Half core PQ, HQ and NQ samples are prepared for assay and
the remaining material is retained in the core farm for future reference. Each
assay batch is submitted with duplicates and standards to monitor laboratory
quality. Total depth (end of hole) is rounded to one decimal place for
reporting purposes. Collars denoted with a * show partial results, with
further significant assays to be reported in subsequent exploration updates.
Hole ID denoted with * partial results, assays pending; ** partial intercept,
assays pending; ^ updated intercept or ^^ previously reported intercept
