Drilling Results at Havieron Highlight Potential New Eastern Breccia Target
Newcrest reports further excellent drilling results from Havieron, including the best intercept to date, 120.7m @ 9.3g/t Au and 0.18% Cu from 1349.3m (HAD065W2)
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 Greatland's Havieron deposit in the Paterson region of Western Australia. The Company notes the release of an ASX announcement titled "Newcrest Quarterly Exploration Report" by Newcrest Mining Ltd ("Newcrest") earlier today.
At Havieron, exploration activities have focused on an infill drilling programme to support the estimation of an initial Inferred Mineral Resource from the South East Crescent and adjacent breccia, expected in the December 2020 quarter, together with step out drilling to define the extents and growth potential of the Havieron mineralised system. 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 was initially identified internal to the Crescent sulphide zone but most recently has also been recognised external to the Crescent sulphide zone on the east, north-west and south-east.
At this stage, exploration has identified four key target regions, which are:
· South East Crescent and Breccia
· North West Crescent
· Northern Breccia
· Eastern Breccia
Highlights
· Best Intercept to Date: Latest drilling results have returned the best intercept to date at Havieron from infill drilling (HAD065W2, South East Crescent Zone):
· 120.7m @ 9.3g/t Au and 0.18% Cu from 1349.3m, including 26.6m @ 34g/t Au and 0.23% Cu from 1384.4m
· New Eastern Breccia Zone: A potential new fourth target area, the "Eastern Breccia", has been identified by growth drilling from two drill holes, including 342.2m @ 2.0g/t Au, 0.11% Cu from 1536.8m (HAD084). Encouragingly, the new Eastern Breccia highlights the potential for a new region of breccia development not previously recognised and extends mineralisation externally to the ovoid-shaped Crescent sulphide zone.
· Initial Mineral Resource on Track: Further excellent results from infill drilling support the estimation of an initial Inferred Mineral Resource for Havieron in the December quarter from the South East Crescent and adjacent breccia mineralisation.
Best New Results (not previously reported)
· HAD057W5 (SE Crescent and Breccia Zone): 212m @ 2.0g/t Au, 0.11% Cu from 981m, including
· 30.2m @ 5.6g/t Au, 0.17% Cu from 1115m
· HAD065W2 (SE Crescent and Breccia Zone): 120.7m @ 9.3g/t Au, 0.18% Cu from 1349.3m, including
· 26.6m @ 34g/t Au, 0.23% Cu from 1384.4m
· HAD083 (Northern Breccia Zone): 183.7m @ 1.8g/t Au, 0.18% Cu from 1098m, including

· 41.1m @ 3.7g/t Au, 0.1% Cu from 1723.9m
· HAD084 (Eastern Breccia Zone): 342.2m @ 2.0g/t Au, 0.11% Cu from 1536.8m, including
· 14m @ 19g/t Au, 0.2% Cu from 1572m
· HAD089 (Northern Breccia Zone): 91m @ 1.6g/t Au, 0.21% Cu from 697m
· HAD089 (NW Crescent Zone): 116m @ 2.9g/t Au, 0.07% Cu from 1136m, including
· 13m @ 13g/t Au, 0.17% Cu from 1136m
Next Steps
· Exploration programmes at Havieron continue, with both infill drilling to deliver an initial Inferred Mineral Resource and step out drilling to define the extent of the mineralised system.
· Latest drill results provide additional support to the ongoing investigation of both high-grade selective and bulk mining methods.
· Environmental and baseline studies progressing to support potential commencement of decline at Havieron by end of calendar year 2020 or early 2021, subject to market and operating conditions and receipt of all necessary permits, consents and approvals.
· Continuing to investigate potential to achieve commercial production within two to three years from commencement of decline.
Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "We are delighted by the latest set of excellent drilling results at Havieron, including the best intercept at the project to date, which further reinforce the potential for a bulk tonnage mining operation at Havieron. Exploration at Havieron has now identified four key target regions, including the new Eastern Breccia, which was identified by two of the step-out drill holes reported today. Importantly, the footprint of Havieron continues to expand and breccia mineralisation has now been identified outside of the ovoid-shaped Crescent sulphide zone to the east, north-west and south-east.
"As Newcrest's growth drilling programme further expands the footprint of the mineralised system at Havieron, infill drilling has continued in order to support the estimation of an initial Inferred Mineral Resource from the South East Crescent and adjacent breccia mineralisation. We look forward to the delivery of the initial Inferred Mineral Resource from this zone before the end of the year as further drilling continues to define the full extent of the Havieron system."
Analytical results for HAD028W1, HAD053W1, HAD053W2, HAD057W5, HAD065W1, HAD065W2, HAD074W1, HAD083, HAD084, HAD085, HAD087, HAD088, HAD089 and HAD097W1, have been received and are announced today, along with selected significant intercepts from interim reporting; presented in Table 1.

Further Information on Newcrest Drilling and Operations at Havieron
Exploration activities at Havieron are operated by Newcrest under a Farm-in 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 mineral cover. Newcrest commenced drilling at Havieron during the June 2019 quarter and have completed 111,913m of drilling from 120 holes.
Drilling activity progressively increased during the quarter such that up to nine drill rigs are now in operation. A further 34 drill holes for 35,037m of drilling was completed in the quarter to 30 September 2020. All holes intersected mineralisation. Results reported today are from a further 14 holes including wedges, along with holes reported in an interim update dated 10 September 2020. Significant new results are presented in Table 1. Infill and step out drilling results announced today are considered outstanding.
At Havieron, exploration activities have focused on an infill drilling programme to support the estimation of an initial Mineral Resource from the South East Crescent and adjacent breccia, expected in the December 2020 quarter, together with step out drilling to define the extents and growth potential of the Havieron mineralised system.
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 was initially identified internal to the Crescent sulphide zone but most recently has been recognised external to the Crescent sulphide zone on the east, northwest and southeast. The system extents continue to expand with more drilling.
Exploration has identified four key target regions, which are:
· South East Crescent and Breccia
· North West Crescent
· Northern Breccia
· Eastern Breccia
Within the South East Crescent and Breccia region, infill drilling is focused on a nominal drill spacing of 50 - 100m laterally, and 100m vertically. A total of 73 drill holes have been completed to support the estimation of an initial Inferred Mineral Resource in the December 2020 quarter. The majority of this drilling is located in the upper 600m vertical extent of the zone. Interpretation of data in the South East Crescent area suggests:
· The upper levels of the system (-170m to -400mRL) have an internal unfolded strike of 550m, an average width estimate of 20m and a height of 230m.
· The mid level of the system (-400m to -600mRL) has an internal unfolded strike of 400m, an average width estimate of 20m and a height of 200m.
· The lower levels (-600m to -900mRL) where drill tested, hosts the Crescent Zone which tapers in strike length to 300m, with a width of approximately 20m and a height of 300m.
· Breccia mineralisation adjoining the Crescent Zone continues to deliver strong results including HAD065W2.
Infill drilling continues to demonstrate the continuity of higher grade mineralisation within the South East Crescent and Breccia including HAD065W2 which returned 120.7m @ 9.3g/t Au and 0.18% Cu from 1349.3m, including 26.6m @ 34g/t Au and 0.23% Cu from 1384.4m. This result confirms the presence of higher grade shoots within the Crescent Zone and remains open at depth.
In the North West Crescent target, a total of eight drill holes have been completed, of which three have intersected higher grades as part of the initial growth drilling phase. Results and interpretation from the drilling highlighted:
· The presence of high grade sulphide mineralised zones in three drill holes including:
o HAD085 returned 74.2m @ 2.0g/t Au and 0.09% Cu from 568.8m, including 19.1m @ 7.0g/t Au and 0.23% Cu from 594m,
o HAD089 returned 116m @ 2.9g/t Au and 0.07% Cu from 1136m, including 13m @ 13g/t Au and 0.17% Cu from 1136m.
· These intercepts follow on from previously reported drill hole HAD066^^, 82.1m @ 2.4g/t Au and 0.08% Cu from 557.6m.
· Further drill testing is required to determine the continuity and extent of the higher grade mineralisation.
Currently, mineralisation on the limbs between the south-east and north-west closure appears irregularly developed.
The Northern Breccia has been identified in 15 drill holes to date. To date mineralisation is observed from -550 to -850mRL striking to the north west over 300m, between 100-150m in width and open at depth; highlighting a broad bulk tonnage opportunity. Ongoing extensional drilling has confirmed and further expanded the footprint of the Northern Breccia hosted mineralisation.
· Additional results from this breccia include:
o HAD047^^ returned 309m @ 0.99g/t Au and 0.07% Cu from 915m including 44m @ 3.3g/t Au and 0.15% Cu from 1157m, and
o HAD078^^, 208.6m @ 1.2g/t Au and 0.22% Cu from 832.4m including 10.4m @ 4.0g/t Au and 0.11% Cu from 1002.6m.
Growth drilling from two drill holes has identified an exciting new target area termed the "Eastern Breccia". This drilling is encouraging as it highlights the potential for a new region of breccia development not previously recognised and extends mineralisation externally to the Crescent sulphide mineralisation.
· Significant results from the initial two drill holes include:
o HAD083 returned 134m @ 1.4g/t Au and 0.04% Cu from 1529m, and 98.2m @ 1.9g/t Au & 0.14% Cu from 1677m Including 41.1m @ 3.7g/t Au and 0.1% Cu from 1723.9m, and
o HAD084 returned 342.2m @ 2.0g/t Au and 0.11% Cu from 1536.8m, including 14m @ 19g/t Au and 0.20% Cu from 1572m.
· Additional drilling is required to assess the potential of this new zone of breccia mineralisation.
Mineralisation at the Havieron deposit remains open to the north-west and north east, has been observed to over 1,100m below post mineral cover, and remains open at depth. The extents of the Havieron system are still to be defined.
Studies are ongoing and include mining methods, hydrogeology, geotechnical, metallurgical, engineering and environmental to support delivery of an initial Inferred Mineral Resource estimate in Q4 2020.
Newcrest continues to investigate the potential to commence an exploration decline at Havieron by the end of calendar year 2020 or early 2021, subject to market and operating conditions and receipt of all necessary permits, consents and approvals, along with the potential to achieve commercial production within two to three years from commencement of decline.
Stage 3 of the Farm-in is progressing including ongoing exploration drilling and studies to support early development options. Currently, nine drill rigs remain operational. A 100 person camp is on-site to support ongoing operations. Camp expansions and access upgrades are currently underway.
Additional drill hole information is presented in Appendix I and tabulated drill hole intercepts are presented in Appendix II.
Deposit mineralisation 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.
Newcrest has implemented and maintained measures to reduce and mitigate the risk of the COVID-19 pandemic to its project workforce and key stakeholders. Potential impacts of the COVID-19 pandemic on the drilling activity at Havieron are being actively managed and considered as part of the studies underway. There have been no COVID-19 cases at Havieron.
Background to Havieron and Farm-in Agreement with Newcrest
In March 2019, Greatland entered into 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 discovery in the Paterson region of Western Australia. Newcrest has the right to earn up to a 70% interest in Mining Lease 45/1287, a 12 block area that covers the Havieron deposit, by spending up to US$65 million. Newcrest may acquire an additional 5% interest at the end of the Farm-in period at fair market value.
Newcrest has completed Stage 2 of the Farm-in Agreement. In accordance with the terms of the Agreement, Newcrest has earned a 40% interest in the Havieron Project. Newcrest is now progressing Stage 3 work programs including ongoing exploration drilling and studies to support early development options. In order to complete Stage 3 of the Farm-in, Newcrest must incur an additional US$25 million in expenditure and deliver a Pre-Feasibility study for the Havieron Project. If Newcrest successfully completes Stage 3, Newcrest will earn an additional 20% Farm-in Interest (cumulative 60% Farm-in interest).
During the Farm-in and Havieron Joint Venture periods, Newcrest will have a right of first refusal over the remainder of the Havieron licence. During the Farm-In period, Newcrest will have a right of first refusal over Greatland's Black Hills and Paterson Range East licences.
The Farm-in Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration programme and feasibility study, the resulting joint venture ore will be processed at Telfer, located 45km west of Havieron.

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. Newcrest has the right to earn up to a 70% interest in Mining Lease 45/1287, a 12 block area that covers the Havieron deposit, by spending up to US$65 million.
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.

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.
Diamond drilling was advanced from the base of the cover sequence with PQ3, HQ3 and NQ2 diameter coring configuration.
Diamond 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 - 24,644m from 34 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 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.
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 105oC, 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.
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). Gold analyses were determined by 50g fire assay with AAS finish (method FA50N/AA).
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 company personnel and the Competent Person/Qualified Person.
No adjustments are made to assay data, and no twinned holes have been completed. Drilling intersects mineralisation at various angles.
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 drillholes re-surveyed by an external survey contactor using a DeviGyro tool - confirming sufficient accuracy for downhole spatial recording.
Topographic control is established from SRTM (1 second) topographic data and derived digital elevation model. The topography is generally low relief to flat, with an average elevation of 265 m, within dune corridors.
All collar coordinates are provided in the Geocentric Datum of Australian (GDA94 Zone 51S). All relative depth information is reported in Australian Height Datum (AHD).
Data spacing and distribution
The drill hole spacing ranges from 50 - 100m within the south-eastern Crescent sulphide zone to 50-300m in lateral extent within the breccia zone over an area of ~2km2.
Significant assay intercepts remain open. Further drilling is required to determine the extent of currently defined mineralisation. No sample compositing is applied to samples.
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 within currently interpreted dimensions of 650m x 350m trending in a north west orientation and over 900m in vertical extent below cover. Although additional mineralisation has been intersected outside of these dimensions.
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 was transported by vehicle to Telfer core processing facility by Newcrest personnel.
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
Due to the limited duration of the program, no external audits or reviews have been undertaken. Internal verification and audit of Newcrest exploration procedures and databases are periodically undertaken.

Commentary
Mineral tenement and land tenure status
The Havieron Project is entirely contained within mining tenement M45/1287, which is 100% owned by Greatland Pty Ltd and Newcrest Operations Limited. Newcrest has entered into an Exploration Farm-In (EFI) agreement with Greatland Pty Ltd and Greatland Gold Plc effective 12 March 2019, with Newcrest as Manager of the Havieron Project. The Stage 2 expenditure commitment of US$20M under the farm-in agreement with Greatland Gold has been met. Newcrest has earned a 40% interest in the project and is in stage three of a four stage farm-in, in which 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) 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 Mining Limited 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 550m within an arcuate shaped mineralised zone, and to depths of up to -1,100mRL.
Drill hole Information
As provided.
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.

Other substantive exploration data
Nil.
Further work
Further work is planned to evaluate exploration opportunities that extend the known mineralisation. Initial drilling conducted by Newcrest has confirmed higher grade mineralisation, broadened mineralised extents defined by prior drilling and extended the depth of observed mineralisation of the Havieron project. The results of drilling to date indicate the limits of mineralisation have been closed off to the south west and south east, and remain open to the north west, north east, and at depth. Drilling programs at Havieron are ongoing with nine drill rigs currently in operation.
APPENDIX II
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. 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. 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.
Hole ID denoted with * partial results, assays pending; ** partial intercept, assays pending; ^ updated intercept or ^^ previously reported.
