Newcrest Reports Further Drilling Results at Havieron
Further excellent infill and growth drilling results improve continuity of mineralisation and highlight the opportunity to expand footprint of mineralisation at Havieron
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to provide an update on Newcrest's drilling campaign at Greatland's Havieron deposit in the Paterson region of Western Australia. The Company notes the release of an ASX announcement titled "Exploration Update" by Newcrest Mining Ltd ("Newcrest") earlier today.
At Havieron, exploration activities have focused on an infill drilling programme to support the estimation of an initial Inferred Mineral Resource1, separately announced today, together with step out drilling to define the extents and growth potential of the Havieron mineralised system. Drilling since May 2019 has outlined an ovoid shaped zone of variable brecciation, alteration and sulphide mineralisation with dimensions of 650m x 350m x 1000m deep, trending in a north west orientation. Breccia mineralisation was initially identified internal to the Crescent sulphide zone but most recently has also been recognised external to the Crescent sulphide zone on the east, north-west and south-east.
At this stage, exploration has identified four key target regions, which are:
· South East Crescent and Breccia
· North West Crescent
· Northern Breccia
· Eastern Breccia
1 Refer to Newcrest announcement titled "Newcrest announces initial Inferred Mineral Resource estimate for Havieron of 3.4Moz of gold and 160Kt of Copper" dated 10 December 2020 and available on www.asx.com.au under the code "NCM".
Highlights
· Further excellent drilling results: Latest drilling results further improve the continuity of mineralisation and highlight the potential to expand mineralisation footprint at Havieron.
· South East Crescent and Breccia: Latest drill results improve the continuity of higher-grade mineralisation within the South East Crescent and Breccia. Mineralisation is open at depth below the Inferred Mineral Resource shell providing support for potential expansion at depth. Selected results include2:

Further Information on Newcrest Drilling and Operations at Havieron
Exploration activities at Havieron are operated by Newcrest under a Joint Venture Agreement with Greatland. The Havieron deposit is centered on a magnetic anomaly located 45km east of Telfer. Exploration drilling by Greatland during 2018 resulted in the discovery of significant gold and copper mineralisation under 400m of post mineralisation cover. Newcrest commenced drilling at Havieron during the June 2019 quarter and have completed 128,559m of drilling from 134 holes to date.
Drilling activity has progressively increased such that up to eight drill rigs are now in operation. Results reported today are from a further 14 drill holes including wedges for 16,646m of drilling completed since 30 September 2020. All drill holes intersected mineralisation. Significant new results are presented in Table 1. Infill and step out drilling results announced today are considered excellent.
At Havieron, exploration activities have focused on an infill drilling program to support the estimation of an Inferred Mineral Resource1 from the South East Crescent and adjacent breccias, together with step out drilling to define the extents and growth potential of the Havieron mineralised system.
Drilling since May 2019 has outlined an ovoid shaped zone of variable brecciation, alteration and sulphide mineralisation with dimensions of 650m x 350m trending in a north west orientation. Breccia mineralisation has been identified internally and externally to the Crescent zone, including targets which remain open to the east, northwest and southeast. Mineralisation has been observed to greater than 1000m in vertical extent below the post mineral cover sequence and remains open at depth. Within this ovoid shaped zone (at this stage) exploration has identified four key target regions, which are:
· South East Crescent and Breccia
· North West Crescent
· Northern Breccia
· Eastern Breccia
Drill data density in the South East Crescent and adjacent Breccia and a portion of the Northern Breccia has been sufficient for the definition of an Inferred Mineral Resource Estimate for these domains. Reported inside an A$50/t Net Smelter Royalty ("NSR") shell, the volume of identified mineralised geological domains where information to estimate the metal inventory and grades is at a sufficient magnitude and having the reasonable prospects of eventual economic extraction comprises:
· 52Mt @ 2.0g/t Au and 0.31% Cu for 3.4Moz Au and 160Kt Cu for 4.2M Oz's gold equivalent3, included in geological domains:
o Crescent Zone containing 18Mt @ 3.8g/t Au and 0.61% Cu for 2.2Moz Au and 110Kt Cu; and
o Breccia Zone containing 34Mt @ 1.1g/t Au and 0.15% Cu for 1.2Moz Au and 50Kt Cu
3 The gold equivalent (AuEq) is based on assumed prices of US$1,400/oz Au and US$3.40/lb Cu, gold recoveries of 94% (Crescent) and 84% (Breccia), and copper recoveries of 84% (Crescent) and 82% (Breccia), which equates to a formula of approximately AuEq = Au (g/t) + 1.65
* Cu (%). In Greatland's opinion all elements (gold and copper) have a reasonable potential to be recovered and sold.
Outside of the Inferred Mineral Resource estimate, mineralisation remains open with encouraging results identified from the South East Crescent and Breccia Zone, Northern Breccia Zone, and the Eastern Breccia Zone.
Within the South East Crescent and Breccia Zone, a total of five holes have been completed for the reporting period. These drill holes (included in the resource) improve the continuity of higher grade mineralisation within the South East Crescent and Breccia Zone and include:
· HAD056W1
o 205.8m @ 1.2g/t Au & 0.24% Cu from 598m
o Including 31.8m @ 3.1g/t Au & 0.38% Cu from 722m
· HAD057W4
o 100m @ 2.1g/t Au & 0.05% Cu from 1029m
o Including 19.3m @ 6.2g/t Au & 0.07% Cu from 1089.3m
· HAD097W2
o 119.2m @ 2.7g/t Au & 0.40% Cu from 937.8m
o Including 2.8m @ 65g/t Au and 0.46% Cu from 1010.6m
Mineralisation is open at depth below the Inferred Mineral Resource shell providing support for potential resource expansion at depth. Further infill drilling of the South East Crescent and Breccia Zones is ongoing to support potential for delivery of an Indicated Mineral Resource and associated early studies.
Within the Northern Breccia Zone, a total of 10 drill holes have been completed during the reporting period with mineralisation identified in 23 drill holes to date. Results continue to support continuity of mineralisation and demonstrate opportunity to further expand the mineralisation footprint in this region. Results include:
· HAD101
o 92.5m @ 1.9g/t Au & 0.06% Cu from 1296m
o Including 15.6m @ 4.8g/t Au & 0.02% Cu from 1350m
· HAD103
o 90.6m @ 2.3g/t Au & 0.18% Cu from 776.4m,
o including 2.4m @ 67g/t Au and 0.33% Cu from 822.7m
· HAD105
o 298.8m @ 1.2g/t Au & 0.11% Cu from 801.6m,
o including 15.8m @ 3.5g/t Au & 0.22% Cu from 821m
Further drilling of the Northern Breccia Zone is ongoing to support the potential expansion of the existing Inferred Mineral Resource.
Within the Eastern Brecccia Zone a total of one drill hole was completed during the reporting period with mineralisation now identified in three drill holes to date. Drill testing and interpretation of the geological and mineralisation controls of the Eastern Breccia Zone is ongoing.
· HAD101
o 53.3m @ 1.5g/t Au & 0.25% Cu from 1593m
o Including 19.7m @ 1.9g/t Au & 0.2% Cu from 1619m
Mineralisation at the Havieron deposit has been identified internally and externally to the Crescent Zone, including targets which remain open to the east, northwest and southeast. Mineralisation has been observed to greater than 1000m in vertical extent below the post mineralisation cover sequence and remains open at depth. The extents of the Havieron system are still to be defined.
Growth drilling in calendar year 2021 will continue to focus on the above potential extensions and definition of the identified zones. Infill drilling is underway on the top 350 vertical metres of the South Eastern Crescent within the existing resource outline, looking to upgrade some of the Inferred Resource to Indicated.
Early studies are ongoing and include mining methods, hydrogeology, geotechnical, metallurgical, engineering and environmental to support delivery of a Pre-Feasibility Study in late 2021.
Newcrest continues to investigate the potential to commence an exploration decline at Havieron by the end of calendar year 2020 or early 2021, subject to market and operating conditions and receipt of all necessary permits, consents and approvals, along with the potential to achieve commercial production within two to three years from commencement of decline.
Exploration drilling and studies are ongoing to support early development options. Currently, up to eight drill rigs remain operational. A 230 person camp has nearly been completed to support ongoing operations. Access upgrades are currently underway.
Additional drill hole information is presented in Appendix I and tabulated drill hole intercepts are presented in Appendix II.
Deposit mineralisation is hosted by metasedimentary (meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks. Gold and copper mineralisation is hosted in breccia, vein and massive sulphide replacement styles, typical of intrusion-related and skarn types of mineralisation. The main sulphide mineral assemblage contains well developed pyrrhotite-chalcopyrite and pyrite. Alteration assemblages associated with mineralisation are amphibole-carbonate-biotite-sericite-chlorite. Higher grade gold zones (+10g/t Au) are often associated with quartz/chalcopyrite-pyrite veining.
Newcrest has implemented and maintained measures to reduce and mitigate the risk of the COVID-19 pandemic to its project workforce and key stakeholders. Potential impacts of the COVID-19 pandemic on the drilling activity at Havieron are being actively managed and considered as part of the studies underway. There have been no COVID-19 cases at Havieron.
Background to Havieron and Joint Venture Agreement with Newcrest
The Havieron Project is operated by Newcrest under a Joint Venture Agreement with Greatland Gold plc. As announced on 30 November 2020, Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and is entitled to earn an additional 20% joint venture interest, resulting in an overall joint venture interest of 60% (Greatland Gold 40%). Newcrest can earn up to a 70% joint venture interest through total expenditure of US$65 million and the completion of a series of exploration and development milestones in a four-stage farm-in over a six year period that commenced in March 2019. Newcrest may acquire an additional 5% interest at the end of the farm-in period at fair market value.
The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration program and feasibility study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer, located 45km west of Havieron.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed (AIM:GGP) natural resource exploration and development company with a current focus on precious and base metals. The Company has six main projects; four situated in Western Australia and two in Tasmania.
In March 2019, Greatland signed a Farm-in Agreement with Newcrest Operations Limited, a wholly-owned subsidiary of Newcrest Mining Limited (ASX:NCM), to explore and develop Greatland's Havieron gold-copper deposit in the Paterson region of Western Australia. The Havieron Project is operated by Newcrest under a Joint Venture Agreement with Greatland Gold plc. Newcrest can earn up to a 70% joint venture interest through total expenditure of US$65 million and the completion of a series of exploration and development milestones in a four-stage farm-in over a six year period that commenced in March 2019. Newcrest may acquire an additional 5% interest at the end of the farm-in period at fair market value.
The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration program and feasibility study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer, located 45km west of Havieron.
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 |
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 are oriented on 3m and 6m runs using an electronic core orientation tool (Reflex ACTIII). At the end of each run, the bottom of hole position is marked by the driller, which is later transferred to the whole drill core run length with a bottom of hole reference line. |
|
Drill sample recovery |
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 - 10,136m from 14 drillholes, 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 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 the Mineral Resource estimate. |
|
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 Telfer and Havieron core processing facility. Half core samples were collected in pre-numbered calico bags and grouped in plastic bags for dispatch to the laboratory. Sample weights typically varied from 0.5 to 4kg. 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 105oC, 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, the sample and 10 samples either side are re-ground or re-screened. There are very few instances of <95% passing the second grind. An assessment of the grind size verses Au grade has shown that few mineralised assays are affected by grinding issues. 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 programs including pulp samples submitted to an umpire laboratory and combined with more extensive re-submission programs 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 an 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 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 Australian Height Datum (AHD) +5000m. |
|
Data spacing and distribution |
The drill hole spacing ranges from 50-100m within the south-eastern Crescent sulphide zone to 50-300m in lateral extent within the breccia zone over an area of ~2km2. 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. |
|
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 greater than 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 over 600m 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 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 Havieron or Telfer 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 |
Due to the limited duration of the program, no external audits or reviews have been undertaken. Internal reviews of core handling, sample preparation and assays laboratories were conducted on a regular basis by both project personnel and owner representatives. In the Competent Persons opinion, the sample preparation, security and 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, sampling or recovery factors that materially impact the adequacy and reliability of the results of the drilling programme in place at the Havieron Project. |

Mineral tenement and land tenure status |
The Havieron Project is entirely contained within mining tenement M45/1287, which is 100% owned by Greatland Pty Ltd and Newcrest Operations Limited. Newcrest has entered into a Joint Venture Agreement (effective 30 November 2020) and Farm-In Agreement (effective 12 March 2019) with Greatland Pty Ltd and Greatland Gold plc. Newcrest is the Manager of the Havieron Project. Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and is entitled to earn an additional 20% joint venture interest, resulting in an overall joint venture interest of 60% (Newcrest 60% / Greatland 40%). Newcrest has the right to earn up to a 70% interest and acquire a further 5% at fair market value. Newcrest and the Western Desert Lands Aboriginal Corporation are parties to an Indigenous Land Use Agreement (ILUA) which relates to the use of native title land for Newcrest's current operations at Telfer and its activities within a 60-km radius around Telfer and includes its exploration activities at Havieron. The parties have agreed that the ILUA will apply to any future development activities by the Joint Venture Participants (Newcrest and Greatland Gold) at Havieron. The mining tenement M45/1287 wholly replaces the 12 sub-blocks of exploration tenement E45/4701 (former exploration tenement on which the Havieron Project is based) and was granted on 10 September 2020. All obligations with respect to legislative requirements including minimum expenditure are maintained in good standing for prior exploration tenement E45/4701. |
|
Exploration done by other parties |
Newcrest Mining Limited completed six core holes in the vicinity of the Havieron Project from 1991 to 2003. Greatland Gold completed drill targeting and drilling of nine Reverse Circulation (RC) drill holes with core tails for a total of approximately 6,800m in 2018. Results of drilling programs conducted by Greatland Gold have previously been reported on the Greatland Gold website. 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 9km thick sequence of marine sedimentary rocks and is entirely overlain by approximately 420m of Phanerozoic sediments of the Paterson Formation and Quaternary aeolian sediments. 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 is hosted by metasedimentary rocks (meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks of an undetermined age. The main mineral assemblage contains well developed pyrrhotite-chalcopyrite and pyrite sulphide mineral assemblages as breccia and vein infill, and massive sulphide lenses. The main mineralisation event is associated with amphibole-carbonate-biotite-sericite-chlorite wall rock alteration. Drilling since May 2019 has outlined an ovoid shaped zone of variable brecciation, alteration and sulphide mineralisation with dimensions of 650m x 350m trending in a north west orientation. Breccia mineralisation is identified both internal and external to the sulphide Crescent zone. Mineralisation has been observed to greater than 1000 m below the post mineralisation cover sequence (1400metres below surface) and remains open at depth. The geological model has been reviewed and validated by GeoAqua Consultants. |

|
Data aggregation methods |
Significant assay intercepts are reported as (A) length-weighted averages exceeding 1.0g/t Au greater than or equal to 10m, with a maximum of 5m consecutive internal dilution; and (B) length-weighted averages exceeding 0.2g/t Au for greater than or equal to 20m, with a maximum of 10m consecutive internal dilution, and (C) intervals of >30g/t with no internal dilution which are greater or equal to 30 gram metres (Au_ppm x length). No top cuts are applied to intercept calculations. |
|
Relationship between mineralisation widths and intercept lengths |
Significant assay intervals reported represent apparent widths. Drilling is not always perpendicular to the dip of mineralisation and true widths are less than downhole widths. Estimates of true widths will only be possible when all results are received, and final geological interpretations have been completed. |

Further work |
Mineralisation at the Havieron deposit has been identified internally and externally to the Crescent zone, including targets which remain open to the east, northwest and southeast. Mineralisation has been observed to greater than 1000m in vertical extent below the post mineral cover sequence and remains open at depth. The extents of the Havieron system are still to be defined. Growth drilling in calendar year 2021 will continue to focus on the above potential extensions and definition of the identified zones. Infill drilling is underway on the top 350 vertical metres of the South Eastern Crescent within the existing resource outline, looking to upgrade the resource category to Indicated. |
APPENDIX II
Drillhole Data
Havieron Project, Paterson, Western Australia
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 uncut sample grades. 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 with no internal dilution which are greater or equal to 30 gram metres (Au_ppm x length) are tabled. Gold 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.
Hole ID denoted with * partial results, assays pending; ** partial intercept, assays pending; ^ updated intercept or ^^ previously reported.
