Havieron Exploration and Development Update

 

Total development at Havieron surpasses 1,850m

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 "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).

Highlights

§ Decline development: significant progress continues to be made with total
development now exceeding 1,850m including over 1,520m advance of the main
access decline

§ Geotechnical conditions: improved geotechnical conditions have enabled
increased productivity resulting in development outperforming the current
schedule by 10%

§ Drilling results: drilling confirms the presence of high grade gold and
copper mineralisation outside the current Mineral Resource with recent results
including:

- Northern Breccia: 29.9m @ 3.9g/t Au and 0.01% Cu from 945.1m

- Eastern Breccia: 57m @ 2.1g/t Au and 0.19% Cu from 1,262m

 

Greatland Managing Director, Shaun Day, commented:

"The Havieron team continues to deliver strong results at the project. Total
development has now surpassed 1,850m and pleasingly, decline development is
continuing ahead of the current schedule."

"Our most recent drilling activities highlight the potential of high grade
mineralisation outside the Southeast Crescent which could add significant
value to the mine plan at Havieron with additional gold and copper
mineralisation intersected at the Northern and Eastern Breccia zones."

Development Update

The main decline continues to progress ahead of the current schedule having
surpassed 1,520m.  Decline support excavations for ventilation, services and
materials handling takes the total development to over 1,850m.

The total advance is 10% ahead of the current schedule due to improved
geotechnical conditions and the ongoing focus on productivity improvements.

Drilling Update

Drilling activities at Havieron recommenced at the beginning of February 2023
with three drill rigs onsite and four holes completed for a total of 5,214m.
This most recent drilling takes the total drilling at the project to 331 holes
for 293,878m.

Drilling has targeted growth opportunities within the Havieron mineral system
at the Eastern Breccia and Northern Breccia domains with step out drilling to
investigate near mine geophysical targets ongoing.  The focus has now shifted
to the evaluation of the deeper portions of the existing Southeast Crescent
Mineral Resource, with drillholes HAD133W10, HAD171 and HAD172 completed since
the beginning of February 2023 (see Figures 2 and 3).

New assay results have been received for four new drill holes along with final
assays for lower priority areas from three holes completed in late 2022 (see
Figures 1 and 2). Of these results, one hole within the Northern Breccia and
one within the Eastern Breccia returned significant assay intercepts in excess
of 50-gram metres of gold (Au ppm x length metres).

current growth targets within the Havieron Deposit, Southeast Crescent,
Northern Breccia, Northwest Pod and Eastern Breccia targets in relation to the
existing mineralised extents.  Also highlighted are all newly reported
drilling result locations.

Northern Breccia

At the Northern Breccia (see Figures 1, 3 and 5), HAD098W9 was aimed at
extending a zone of previously identified high-grade mineralisation.
Encouragingly, the drill hole successfully intercepted several zones of
mineralisation including 29.9m @ 3.9g/t Au and 0.01% Cu from 945.1m.

Eastern Breccia

At the Eastern Breccia (see Figures 1, 3 and 4), HAD164W3 was aimed at testing
the intersection with the Northern Breccia mineralisation. This drillhole
successfully intercepted two significant zones of mineralisation:

§ The upper zone which is situated over 200m vertically above the existing
Mineral Resource - 57m @ 2.1g/t (mailto:57m@2.1g/t) Au and 0.19% Cu from
1,262m including 10m @ 8.5g/t Au and 0.29% Cu from 1,307m

§ The lower copper rich zone confirms the Mineral Resource at that position -
34m @ 0.8g/t Au and 0.61% Cu from 1,438m

(Previously reported holes are not shown for the sake of clarity. Note some
holes and results appear on multiple sections due to the sections' orientation
and overlap.)

Near-Mine Step Out

The two near-mine drillholes (HAD169 and HAD170) were part of a recent
programme evaluating geophysical targets outside of the Havieron mineral
system.  While no significant results were returned, the geological
information derived from these more remote holes will be valuable in informing
and improving the Havieron targeting models.

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). 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
                                                          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

 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

                                                          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

                                                          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 collar locations were surveyed using a differential GPS with GNSS with a
                                                          stated accuracy of +/- 0.5m for all drill holes reported.

                                                          Drill rig alignment was attained using an electronic azimuth aligner. Downhole
                                                          survey was collected at 6-12m intervals in the cover sequence, and every 6 to
                                                          30m in diamond drill core segments of the drill hole using single shot (Axis
                                                          Mining Champ Gyro). The single shot surveys have been validated using
                                                          continuous survey to surface (Axis Mining Champ) along with a selection of
                                                          drill holes re-surveyed by an external survey contactor using a DeviGyro tool
                                                          - confirming sufficient accuracy for downhole spatial recording.

                                                          A LIDAR survey was completed over the project area in Nov 2019 which was used
                                                          to prepare a DEM / topographic model for the project with a spatial accuracy
                                                          of +/- 0.1m vertical and +/- 0.3m horizontal. The topography is generally low
                                                          relief to flat, elevation within the dune corridors in ranges between 250-265m

                                                          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 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

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. Collars
denoted with a ** show partial results, with any further significant assays to
be reported in subsequent updates.
