Newcrest Reports Further Outstanding Drill Results at Havieron
Stage 2 of Farm-in expected to be completed by end of March 2020
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 100% owned Havieron deposit in the Paterson region of Western Australia.
Greatland notes the release of an ASX announcement titled "Exploration and Guidance Update" by Newcrest Mining Ltd ("Newcrest") earlier today.
Highlights
· Drilling at Havieron continues to expand and demonstrate the continuity of high-grade mineralisation, which now extends over a strike length of 450m, to vertical depths of 600m and remains open at depth and to the northwest.
· Results to date support potential for both high-grade selective and bulk mining methods, which are currently being evaluated.
Best new results:
· HAD022: 142m @ 1.9g/t Au, 0.38% Cu from 534m, including
· 15.7m @ 9.8g/t Au, 0.61% Cu from 572.3m
· HAD042: 124m @ 3.9g/t Au, 0.21% Cu from 734m, including
· 17.3m @ 19g/t Au, 0.62% Cu from 790.7m
· HAD044: 83.3m @ 5.0g/t Au, 1.1% Cu from 489.5m
· HAD049: 82m @ 6.1g/t Au, 0.41% Cu from 461m
Next Steps
· Drilling activity continues to ramp up (eight rigs now operational) with the aim of delivering a maiden resource in the second half of calendar year 2020.
· Greatland expects Newcrest to complete Stage 2 of Farm-in by end of March 2020.
· A number of environmental, geotechnical and metallurgical studies are continuing in order to support a potential mineral resource estimate, and future permitting requirements.
· Newcrest is investigating the potential to start an exploration decline at Havieron by end of calendar year 2020 or early 2021, and the potential to achieve commercial production within 2-3 years from commencement of decline.
Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "We are delighted by this sixth consecutive set of excellent results from Newcrest's drilling campaign, which continue to demonstrate the continuity of high-grade mineralisation and expand the mineralised footprint. These latest results represent one of the best sets of drilling results at Havieron since Newcrest began its exploration campaign and reinforce the potential to accelerate the timetable for commercial production.
"As we enter the Australian exploration season, Newcrest continues to drill Havieron at pace and will shortly complete Stage 2 of the Farm-in. Meanwhile, we are planning to be very active with our own systematic exploration campaign across the Paterson, which will focus on drill testing many of the high-priority targets we identified last year."
Analytical results for HAD022, HAD029, HAD038, HAD042, HAD044, HAD045, HAD047 and HAD049 have been received and are announced today. Significant intercepts are 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 centred 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.
Analytical results released today are considered outstanding (Table 1). The results today represent one of the best set of drilling results at Havieron since Newcrest began its exploration campaign: based on gold gram-metre calculations, three holes reported today have in excess of 400 gold gram-metres (HAD042, HAD044 and HAD049) with best result of 500 gold gram-metres (82m @ 6.1 g/t Au, 0.41% Cu from 461m - HAD049).
A further 10,062m of new drilling has been completed since December 2019. Ongoing drilling and assay results confirm broad widths of gold mineralisation at Havieron. Drilling at Havieron continues to expand and demonstrate the continuity of high grade mineralisation which now extends over a strike length of 450m, to vertical depths of 600m and remains open at depth and to the northwest. This zone is supported by 25 mineralised intercepts to date.
Drilling has also further developed understanding of mineralised breccias proximal to the arcuate mineralised zone, with broad intercepts supporting potential for bulk mineable options. Best grades within the breccia zone are developed within 100m of the arcuate mineralised zone. The mineralised breccias have been observed to 1200m below surface and remain open at depth. Further drilling is required to understand the controls and dimensions of breccia-related mineralisation.
Results to date support potential for both high-grade selective and bulk mining methods, which are currently being evaluated. An additional 20,000 metres of drilling is planned by Newcrest to support the objective of delivering a maiden resource estimate in the second half of calendar year 2020. A number of environmental, geotechnical and metallurgical studies are continuing in order to support a potential mineral resource estimate, and future permitting requirements.
Stage 2 of the Farm-in continues. Currently, eight drill rigs are operational. An expanded 90 person camp is on-site to support ongoing operations. Greatland expects Newcrest to complete Stage 2 of the Farm-in Agreement by the end of March 2020.
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.
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 a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m. Newcrest may acquire an additional 5% interest at the end of the Farm-in period at fair market value.
Greatland's Paterson project covers more than 385 square kilometres in the Paterson region of Western Australia and includes the Havieron licence, the Paterson Range East licence, and the Black Hills licence.

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. All projects are 100% owned by Greatland.
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 a 12-block area within E45/4701 that covers the Havieron target 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.
APPENDIX I
Havieron Project (Greatland Gold plc farm-in agreement): JORC Table 1
Section 1 Sampling Techniques and Data
Criteria | Commentary |
Sampling techniques | Diamond core samples are obtained from diamond drilling in Proterozoic basement lithologies. PQ-HQ and NQ diameter diamond core was drilled on a 6m run. Diamond core was cut using an automated core-cutter and half core sampled at 1 m intervals with breaks for major geological changes. Sampling intervals range from 0.2 - 1.0 m. 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 420 m 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 | Diamond core recovery is systematically recorded from the commencement of diamond 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. Diamond 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 diamond core drilled - 6,251.3m), 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. Diamond 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 4 kg. 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 Intertek Laboratory, Perth. Samples were dried at 105oC, and crushed to 95% passing 4.75 mm, and the split to obtain up to 3 kg sub-sample, which was pulverised (using LM5) to produce a pulped product with the minimum standard of 95% passing 106 μm. 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 diamond drill core samples was conducted at Intertek, Perth. 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 50 g 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 Acquire database and assessed for accuracy and precision for recent data. Extended quality control programs have commenced with pulp samples submitted to an umpire laboratory and combined with more extensive re-submission programs. Analysis of the available QC 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. No adjustments are made to assay data, and no twinned holes have been completed. Drilling intersects mineralisation at various angles. |
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 6-12 m intervals in the cover sequence, and every 6 to 30 m in diamond drill core segments of the drill hole. At the end of hole, all holes have been surveyed using a continuous gyro survey to surface (Axis Mining Champ Gyro). 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). |
Data spacing and distribution | The drill hole spacing ranges from 50 - 500 m in lateral extent within an area of 1.5 square kilometres. The current drill hole spacing does not provide sufficient information for the estimation of a Mineral Resource. 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. Mineralised zones have been modelled to be steeply dipping and have an arcuate shape, which remains open to the north west, and at depth. Geological modelling has been interpreted from historic and Newcrest drill holes. Drilling of reported holes HAD022, HAD029, HAD037, HAD038, HAD039 and HAD049 are oriented perpendicular to a central dolerite dyke. The dolerite dyke has a north-south orientation, with drilling established on an east-west orientation. Drilling direction has been modified for subsequent drill holes HAD042, HAD043, HAD045, HAD046 and HAD047 in order to intersect perpendicular to modelled positions of the high grade sulphide mineralisation zones; drill holes have been oriented on a NE and NW drill direction in order to intersect the mineralised zone at an intersection angle of greater than 40 degrees. The high-grade arcuate mineralised sulphide zone has a true thickness between 10 and 30 m, and has been defined over a strike length of up to 450 m, and over 600 m in vertical extent. Mineralised breccias are observed, however the orientation and extents of the breccia bodies are yet to be defined by drilling, and remain open at depth. |
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 Telfer core processing facility. 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. |
Section 2 Reporting of Exploration Results
Criteria | Commentary |
Mineral tenement and land tenure status | The Havieron Project is entirely contained within 12 sub-blocks of E45/4701, which is 100% owned by Greatland Pty Ltd. 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 1 expenditure commitment of US$10m under the Farm-in agreement with Greatland Gold has been met and Newcrest has provided notice that it wishes to proceed to Stage 2. There is a current ILUA (Indigenous Land Use Agreement) signed in December 2015 which extends to the Havieron Project. All obligations with respect to legislative requirements including minimum expenditure are maintained in good standing. The exploration tenement E45/4701 was first granted 17 July 2017 for 5 years, expiring 16 July 2022. |
Exploration done by other parties | Newcrest Mining Limited completed six diamond core holes in the vicinity of the Havieron Project from 1991 to 2003. Greatland Gold completed drill targeting and drilling of 9 Reverse Circulation (RC) drill holes with diamond tails for a total of approximately 6,800 m in 2018. Results of drilling programs conducted by Greatland Gold have previously been reported on the Greatland Gold web site. 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 9 km thick sequence of marine sedimentary rocks, and is entirely overlain by approximately 420 m 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 at the prospect 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 450 m 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 1.0 g/t Au greater than or equal to 10 m, with less than 5 m of consecutive internal dilution; and (B) length-weighted averages exceeding 0.2 g/t Au for greater than or equal to 20 m, with less than 10 m of consecutive internal dilution, and (C) and intervals of >30 gram metres (calculated as the weighted average of consecutive assayed interval multiplied by the Au grade in ppm exceeding a value 30, with no internal dilution). No top cuts are applied to intercept calculations. |
Relationship between mineralisation widths and intercept lengths | Significant assay intervals reported represent apparent widths. Insufficient geological information is available to confirm the geological model and true width of significant assay intervals. |
Diagrams | As provided. |
Balanced reporting | This is the sixth release of Exploration Results for this project made by Newcrest. The initial Newcrest release is dated the 25 July 2019. The second release is dated the 10 September 2019. The third release is dated the 24 October 2019. The fourth release is dated 2 December, 2019. The fifth release is dated 30 January, 2020. Earlier reporting of exploration programs conducted by Newcrest and Greatland Gold have previously been reported. Exploration drilling programs are ongoing and further material results will be reported in subsequent Newcrest releases. |
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 prospect. The results of drilling to date indicate the limits of mineralisation have been closed off to the east, and south, and remain open to the north, and at depth. Drilling programs at Havieron are ongoing with eight drill rigs currently in operation. |
