NEWS RELEASE | 27 April
2023

 

 

Havieron Exploration and Development Update

 

Total development at Havieron surpasses 2,025 metres

Drilling intercepts significant zones of gold and copper mineralisation

 

 

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS STIPULATED UNDER THE UK
MARKET ABUSE REGULATIONS.  ON PUBLICATION OF THIS ANNOUNCEMENT VIA A
REGULATORY INFORMATION SERVICE, THIS INFORMATION IS CONSIDERED TO BE IN THE
PUBLIC DOMAIN.

Greatland Gold plc (AIM:GGP) ("Greatland" or the "Company") is pleased to
provide an exploration and development update for Havieron, its flagship
gold-copper project located in the Paterson Province of Western Australia
(Newcrest Mining Limited ("Newcrest") is Greatland's 70% joint venture partner
in Havieron and today released its Quarterly Report for the three months ended
31 March 2023 which included an update on Havieron).

Highlights

§ Decline development: significant progress continues with total development
now exceeding 2,025m including over 1,600m of advance in the main access
decline (as at 19 April 2023)

§ Drilling results: drilling continues to intersect high grade gold and
copper mineralisation within the SE Crescent Resource and outside the current
Mineral Resource at the Eastern Breccia target.  Recent results include:

-  SE Crescent: 54m @ 8.5g/t Au & 0.32% Cu from 1,421m

-  Eastern Breccia: 31.1m @ 4.9 g/t Au & 0.13 % Cu from 1,635m

 

Greatland Managing Director, Shaun Day, commented:

"The Havieron team continues to deliver strong results at the project.  Total
development has now surpassed 2,025m and pleasingly, decline development is
continuing in line with the schedule.

Our most recent drilling activities highlight the high grade nature of the SE
Crescent zone. In addition, drilling has delivered high grade intercepts
outside of the present Havieron mine plan, including additional gold and
copper mineralisation intersected at the northern limits of Eastern Breccia
zone."

Development Update

The main decline continues to progress ahead of the current schedule, having
surpassed 1,600m.  Decline support excavations for ventilation, services and
materials handling takes the total development to over 2,025m.

Further to advanced preparation by the site team, Cyclone Ilsa was safely
navigated and the impact on site activity minimised.

Drilling Update

Drilling activities at Havieron have progressed on schedule with three drill
rigs operating and four holes completed for a total of 4,550m.  This most
recent drilling takes the total at the project to 335 holes for 298,428m.

The current growth drilling campaign is now complete with the results to
support ongoing Mineral Resource assessment.  Drilling which is currently
focused on hghlightinfill targeting the lower SE Crescent zone is expected to
be completed in the June 2023 quarter.  It is expected that subsequent
drilling will take advantage of underground drilling platforms once
appropriate access is established.

Assay results have been received for six new drill holes along with final
assays for lower priority areas from two previously reported drill holes (see
Figures 1 and 2). Of these results, three holes within the SE Crescent and one
within the Eastern Breccia returned significant assay intercepts in excess of
50-gram metres of gold (Au ppm x length).

locations.

 

 

 

SE Crescent

At the SE Crescent, drilling was aimed at infilling the existing Mineral
Resource below the 4,000mRL, with assays for holes HAD133W10, HAD152W6, HAD172
& HAD171 returning the following high-grade intercepts (see Figures 2, 3
and 4).

§ HAD133W10

-  30m @ 2.6g/t Au & 0.32% Cu from 1,236m, including 14m @ 4.7g/t Au
& 0.39% Cu from 1,236m

-  60m @ 2.6g/t Au & 0.03% Cu from 1,284m

-  54m @ 8.5g/t Au & 0.32% Cu from 1,421m, including 14m @ 26.6g/t Au
& 0.42% Cu from 1,447m

§ HAD152W6

-  79m @ 0.6g/t Au & 0.11% Cu from 1,598m

§ HAD171

-  54m @ 1.0g/t & 0.07% Cu from 1,336m

-  103m @ 2.0g/t Au & 0.23% Cu from 1,433m

 

Northern Breccia

Results were received for HAD0161 and HAD087W1. Both intercepted broad zones
of mineralisation (see Figures 2 and 3).

§ HAD087W1

-  41m @ 0.5g/t Au from 1,424m

§ HAD161

-  77m @ 0.59g/t Au & 0.05% Cu from 1,134m

Eastern Breccia

The Eastern Breccia is developed below the 4,100mRL (approximately 1,150m
below surface) with a footprint of over 500m in strike, up to 200m in width,
and over 250m in vertical extent. Within this zone, multiple northwest
trending internal higher-grade (>1g/t Au) sulphide dominated domains were
observed with the following intercepts returned for HAD098W9 and HAD134W2 (see
Figures 2, 3 and 5).

§ HAD098W9

-  31.1m @ 4.9g/t Au & 0.13% Cu from 1,635m including 10m @ 13.4g/t Au
& 0.14% Cu from 1,655m

Juri Joint Venture

The Juri Joint Venture is a farm-in and joint venture agreement with Greatland
with respect to the Black Hills and Paterson Range East projects, located
within the Paterson Province approximately 50km from the Telfer operation and
in proximity to the Havieron Project. The joint venture covers an area of
approximately 248km(2). Greatland currently has a 49% participating interest
in the Juri Joint Venture and is manager.  Under the terms of the agreement,
Newcrest has the potential to earn an additional 24% joint venture interest
through expenditure of a further A$17 million by October 2024.  Field
activities were paused over the Summer months with ongoing target generation
and project review activities conducted.  The Juri Joint Venture partners are
now working together to confirm a programme for the year ahead.

About Greatland

Greatland is a mining development and exploration company focused primarily on
precious and base metals.

The Company's flagship asset is the world-class Havieron gold-copper project
in the Paterson Province of Western Australia, discovered by Greatland and
presently under development in joint venture with ASX gold major, Newcrest
Mining Limited.

Havieron is located approximately 45km east of Newcrest's existing Telfer gold
mine. The box cut and decline to the Havieron orebody commenced in February
2021 and continues to accelerate with project record advancement achieved in
the December 2022 quarter.  Havieron is intended to leverage the existing
Telfer infrastructure and processing plant. Access to Telfer will de-risk the
development, reduce capital expenditure and lower the project's carbon
footprint.

Greatland has a proven track record of discovery and exploration success and
is pursuing the next generation of tier-one mineral deposits by applying
advanced exploration techniques in under-explored regions. Greatland has a
number of exploration projects across Western Australia and in parallel to the
development of Havieron is focused on becoming a multi-commodity miner of
significant scale.

APPENDIX 1

Havieron Joint Venture: 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 is oriented on 3m and 6m runs using an
                                                          electronic core orientation tool (Reflex ACTIII or equivalent). 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, 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 Havieron core processing facility. Half core
                                                          samples of between 0.2 and 2.0 m 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 8kg. 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. Routine grind size analysis is conducted.

                                                          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 an
                                                          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 programmes including pulp samples submitted to an
                                                          umpire laboratory and combined with more extensive re-submission programmes
                                                          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.

                                                          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 collars were surveyed using real time kinematic (RTK) GPS, with an
                                                          accuracy of ±10mm E/N & ±20mm RL, 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

                                                          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 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 required 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 siliciclastic 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
                                                          within 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 extended to over 700m 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 Havieron facility.

                                                          High resolution core photography and cutting of drill core was undertaken at
                                                          the Havieron 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

APPENDIX 2

Drillhole Data and Au- Cu Significant Intersections for Havieron Joint Venture

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 samples grade, and only those intercepts with average
grades above 0.5g/t Au are reported. 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 which are
greater or equal to 30 gram metres (Au_ppm x length) are tabled. Gold and
copper 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.
