are further assessed

 

Shaun Day, Greatland Managing Director, commented: "Tremendous progress has
been achieved in advancing the decline in recent months. The improved ground
conditions has enabled record rates of advancement."

"Results from the growth drilling programme towards the end of 2022 continued
to identify higher grade extensions to the mineralisation in the Northern
Breccia and Eastern Breccia."

"The success of the drilling programme supports the expectation for Havieron
to deliver an expanded mineral resource estimate."

 

HAVIERON ACTIVITIES UPDATE

Background

Havieron, a gold-copper project located in the Paterson region of Western
Australia, is a 30:70 joint venture between Greatland and Newcrest
respectively ("Joint Venture").  Havieron was discovered by Greatland in 2018
with Newcrest having earned into the project.

The Joint Venture commenced drilling during the June 2019 quarter and has
completed 288,664 metres of drilling.  The Joint Venture commenced the box
cut and decline in February 2021 and Feasibility Study work remains ongoing.

Havieron is located approximately 45km east of Newcrest's Telfer mine.
 Subject to a positive Feasibility Study and decision to mine, it is
contemplated that the Joint Venture will leverage the existing Telfer
infrastructure and processing plant.

A regional map showing the Havieron licence area with regional targets and
adjacent landholdings is available at www.greatlandgold.com/paterson
(https://greatlandgold.com/paterson/)

 

Drilling Update

A further 5,580 metres of drilling from 7 new holes has been completed since
Greatland's last RNS Announcement on 8 December 2022 titled "Havieron
Exploration and Development Update".

Assay results are now reported from 1 new hole completed during this period
and from 9 holes completed during the previous period (see Figures 1 and 2
below).  Of these, 4 holes returned significant assay intercepts in excess of
50 gram metres of gold (Au ppm x length metres). A total of 7 holes have been
completed with assay results pending.  All reported results are set out in
Appendix 2 of this RNS Announcement.

current growth targets, SE Crescent, Northern Breccia, NW Pod and Eastern
Breccia targets in relation to the existing mineralised extents. Also
highlighted are all newly reported growth drilling result locations.

 

Growth drilling has been focused on the Northern Breccia and Eastern Breccia
and on testing the mineral systems depth potential, while camp-scale
exploration holes are underway to test targets outside the main Havieron
mineralised system (Figure 2).

Au LeapfrogTM grade shells with highlighted newly reported intercepts for this
period. This diagram highlights new >50gram metres intersections. Refer to
the inset diagram for relationship to all Havieron drilling.

The Joint Venture continues with a growth drilling programme which has the
potential to expand the Havieron Mineral Resource (see Newcrest ASX
Announcement, 19 August 2022, Annual Mineral Resources and Ore Reserves
Statement as at 30 June 2022).

Assays have been received for 6 holes targeting strike and depth extensions of
the Eastern Breccia. A further 2 holes are drilled with results pending. The
Eastern Breccia is developed below the 4,100RL (all relative depth ("RL")
information is reported in Australian Height Datum ("AHD") +5,000 metres) with
a footprint of over 500m in strike, up to 200m in width, and over 250m in
vertical extent.

The zone of high-grade mineralisation returned in HAD134W1 (42.0m @ 2.4 g/t Au
& 0.43% Cu) represents one of the recently defined northwest trending
internal higher-grade sulphide dominated domains with strong similarities to
the high grade South East Crescent, in the Eastern Breccia (see Figure 5).
 This mineralisation, along with much of the Eastern Breccia system, remain
open at depth.

Summary results include:

HAD134W1

§ 42.0m @ 2.4 g/t Au & 0.43% Cu from 1,542m

HAD152W4

§ 86.0m @ 0.88g/t Au & 0.05% Cu from 2,056m

HAD163W1

§ 171.1m @ 0.7g/t Au & 0.04% Cu from 1,458m

HAD164W2

§ 68.0m @ 0.9g/t Au & 0.14% Cu from 1411m

Assays have been received for 2 holes that were aimed at defining the
high-grade domains within the boarder Northern Breccia (see Figure 3 and
Figure 4).  A further 3 holes are drilled with assays pending.

Summary results include:

HAD098W8

§ 137.0m @ 1.0g/t Au & 0.10% Cu from 1,110m

§ 22.0m @ 8.1 g/t Au & 0.14% Cu from 1,287m

HAD161

§ 77m @ 0.6g/t Au & 0.05% Cu from 1,134m

Drilling to test geophysical targets outside of the known Havieron mineralised
system, including evaluating the Havieron dolerite at multiple intervals north
and south of the Havieron mineralised envelope, revealed no significant
intercepts. Two holes testing to the northwest and southeast holes are
awaiting assays (HAD169 & HAD170).

intersections drilled during the period.

 

Development Update

Development of the decline saw ground conditions improve with 1,519 metres now
complete (as at 18 January 2023).

Advance rates for the decline continue to increase with the project's highest
daily average advancement rates being set since the last update in December
2022 after the transition to drilling and blasting of the development face.
Further progress continued to be constrained by geotechnical and
hydrogeological conditions.

Works are ongoing to progress the approvals and permits required for
construction and production at Havieron.

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 - 15,824m for 21
                                                          drill holes, all intersecting mineralisation), including orientation of key
                                                          geological features.

                                                          Geotechnical measurements were recorded including Rock Quality Designation
                                                          (RQD) fracture frequency, solid core recovery and qualitative rock strength
                                                          measurements.

                                                          Magnetic susceptibility measurements were recorded every metre. The bulk
                                                          density of selected drill core intervals was determined at site on whole core
                                                          samples.

                                                          All geological and geotechnical logging was conducted at 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
                                                          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 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
                                                          Australian Height Datum (AHD) steepening to the southeast. All collar
                                                          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 siliclastic sedimentary facies, mineralised
                                                          breccia and sub-vertical intrusive lithologies. Geological modelling has been
                                                          interpreted from historic and Newcrest drill holes.

                                                          Variable brecciation, alteration and sulphide mineralisation is observed with
                                                          a footprint 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
                                                          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                                        Internal reviews of core handling, sample preparation and assays laboratories
                                                          were conducted on a regular basis by both project personnel and owner

                                                          analytical procedures are consistent with current industry standards and are
                                                          entirely appropriate and acceptable for the styles of mineralisation
                                                          identified and will be appropriate for use in the reporting of exploration
                                                          results and Mineral Resource estimates. There are no identified drilling,

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 further significant assays to be
reported in subsequent exploration updates.
