Update on Activities at Havieron:

 

·     Phase 2 drilling programme has commenced with six drill rigs now in operation.

·     Drilling is ongoing to demonstrate the continuity and extent of the high-grade mineralisation.

·     Upgrade to the Havieron camp is largely completed, providing additional facilities to meet the increased scale of the campaign.

·     Newcrest has met the minimum expenditure commitment (USD $5 million) ahead of the expected timetable.

 

Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "We are delighted to report this third set of excellent, high-grade results from Havieron since Newcrest commenced drilling at the project in May this year. These results further extend the limits of known mineralisation, with mineralisation now observed over 950 metres of vertical extent, and underline our belief that Havieron could become a large, underground mining operation - a prospect which has been significantly accelerated through Newcrest's involvement.

 

"In particular, I would like to highlight the outstanding results from hole HAD018 (including 96.4m @ 4.5g/t gold, 0.14% copper from 916.4m) which confirm the presence of higher-grade mineralisation on a step out drill section to the north where HAD012 also previously intersected higher-grade mineralisation.

 

"We are very pleased by Newcrest's continued enthusiasm and commitment to the project, as evidenced by the six drill rigs that are now in operation, and look forward to providing further updates on the drilling campaign at Havieron."

Background to Havieron and Farm-in Agreement with Newcrest

 

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 project in the Paterson region of Western Australia. Newcrest has the right to acquire up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m.

 

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.

 

Limited historical drilling was conducted by Newcrest Mining Limited at Havieron during the 1990s and early 2000s where six holes were drilled, all of which intersected significant alteration and gold plus copper anomalism. Thick lower grade zones of gold and copper were intersected by Newcrest and gold grades within these peaked at 15.4g/t and copper to 2.5%.

 

Greatland's drilling campaigns at Havieron during 2018 yielded excellent results, including:

·     HAD001:       121m @ 2.9g/t Au and 0.23% Cu from 497m.

·     HAD003:       21m @ 3.8g/t Au and 0.44% Cu from 418m.

·     HAD005:       103m @ 3.5g/t Au and 0.93% Cu from 459m and;

                        128m@ 7.4g/t Au and 0.54% Cu from 660m.

·     HAD006:       54m @ 2.7g/t Au and 0.79% Cu from 471m and;

                        179.1m @ 1.4g/t Au and 0.47% Cu from 547.9m.

·     HAD008:       67m @ 2.0g/t Au and 0.91% Cu from 426m.

Further Information on Newcrest Drilling and Operations at Havieron

 

The Havieron Project is operated by Newcrest under a farm-in agreement with Greatland.  It is centred on a magnetic anomaly located 45km east of Telfer. The target is overlain by approximately 400m of post mineralised cover. Newcrest commenced drilling during the June 2019 quarter.

 

During the September quarter, 7 holes for 9,180 metres were completed (HAD012-HAD0018). Final assay results have been received for HAD015, HAD016, HAD017 and HAD018 and are reported below. Results for drill holes HAD012, HAD013 and HAD014 were previously reported on 10 September 2019.

 

Hole HAD015 intersected mineralisation approximately 150 metres north of HAD013 and HAD014, a significant step out to the north on Section Line 7597800mN.  Assay results include:

 

·     HAD015:       28m @ 0.96g/t Au, 0.07% Cu from 979m

58m @ 0.38g/t Au, 0.51% Cu from 1,186m

 

Hole HAD016 drilled at -67 degrees towards 272 was a 100m step out to the south of HAD011 and is interpreted to have drilled over the top of the mineralised envelope.  No significant results were returned.

 

Hole HAD017 intersected mineralisation below HAD005, HAD013 (100.9m @ 2.0g/t Au from 479m) and HAD014 (244.6m @ 2.0g/t Au from 450m).  HAD017 was a 100 metre step out to the east (drilling towards the west) to test mineralisation continuity at depth on Section Line 7597650mN.  HAD017 intersected the deepest mineralisation at the project to date - some ~950 vertical metres below the unconformity.  Assay results include:

 

·     HAD017:          124m @ 1.6g/t Au, 0.35% Cu from 780m

                                                incl 15.2m @ 5.7g/t Au, 1.2% Cu from 880.2m

                                                49.6m @ 2.9g/t Au, 0.12% Cu from 1,011.4m

                                                45m @ 7.1g/t Au, 0.08% Cu from 1,077m

                                                70m @ 0.78g/t Au, 0.12% Cu from 1,452m

 

Hole HAD018 was drilled east to west and collared approximately 75 metres northeast of HAD013. Hole HAD018 intersected mineralisation approximately 100 metres north of HAD013 and HAD014 and on the same drill section as HAD012 (139.4m @ 2.9g/t Au, 0.39% Cu from 865.7m, including 43m @ 7.9g/t Au, 0.83% Cu from 900m). HAD018 intersected mineralisation above HAD012 on the eastern side of the central dyke.  On the western side of the central dyke, HAD018 intersected broad widths of mineralisation with numerous localised high-grade intervals. Assay results include:

 

·     HAD018:          75.7m @ 1.9g/t Au, 0.5% Cu from 597.3m

                                                incl 17m @ 1.4g/t Au, 0.99% Cu from 607m

                                                incl 16.2m @ 6.7g/t Au 0.56% Cu from 632.8m

    96.4m @ 4.5g/t Au, 0.14% Cu from 916.4m

                                                incl 15.4m @ 20g/t Au, 0.32 Cu from 928.5m

 

Additional drill hole information is presented in Appendix I and tabulated drill hole intercepts are presented in Appendix II.

 

Assay results from drill holes HAD015 through HAD018 are considered excellent. Drilling conducted by Newcrest has confirmed higher grade mineralisation, broadened mineralised extents and extended the depth of observed mineralisation (now approximately 950 vertical metres below the unconformity). Drill results have defined up to four sub vertical zones of higher-grade mineralisation within a larger mineralised envelope.

 

The results of drilling to date indicate the limits of mineralisation have not been closed off. Drilling programmes at Havieron are ongoing with an additional fifteen holes (HAD019 to HAD033) at various stages of progress and further assay results are awaited.

 

The phase 2 drilling programme is underway, which includes a significant increase in the amount of both step out and infill drilling. Six drill rigs are operational and Telfer continues to provide support to the project. Newcrest's minimum expenditure commitment of US$5m has been met ahead of the expected timetable.

 

Mineralisation at Havieron 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.

Notes for Editors:

 

Greatland Gold plc is a London AIM-listed (AIM:GGP) natural resource exploration and development company with a current focus on gold, copper and nickel exploration projects.

 

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 project in the Paterson region of Western Australia. Newcrest has the right to acquire up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m.

 

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

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 6 m 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), 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 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.

Due to the limited extent of the drilling program to date, extended quality control programs are yet to be undertaken, whereby pulped samples will be 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 (HAD012, HAD013, HAD014, HAD015, HAD016, HAD017 and HAD018).

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

Drilling of reported holes HAD012, HAD013, HAD014, HAD015, HAD016, HAD017 and HAD018 are oriented perpendicular to a central dolerite dyke. The dolerite dyke has a north-south orientation, with drilling established on an east-west orientation.

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. Steeply dipping mineralised zones with a north-south orientation have been interpreted from historic and Newcrest drill holes.

There is presently insufficient information to confirm the geological model or true thickness of mineralised intervals.  

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 and Greatland 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 agreement with Greatland Pty Ltd and Greatland Gold Plc effective 12 March, 2019, with Newcrest as Manager of the Havieron Project. The EFI minimum expenditure commitment of US$5M has been reached.

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 licence E45/4701 was first granted 17th July 2017 for 5 years, expiring 16th 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.

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 (with the exception of HAD018 intercept from 928.5 to 943.9 m, which includes 5.3 m 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. 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 third release of Exploration Results for this project made by Newcrest. The initial Newcrest release is dated the 25th July 2019. The second release is dated 10th September 2019. 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 not been closed off. Drilling programs at Havieron are ongoing.
