NEWS RELEASE | 30 May 2023
Farm-in to Rio Tinto Exploration's highly prospective Paterson South tenure
Exploration farm-in and joint venture arrangement entered into with Rio Tinto Exploration
Greatland secures access to highly prospective tenure
Enhanced alignment between the discoverers of the world-class Havieron and Winu deposits
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 announce that the Company has entered into a farm-in and joint venture arrangement with global mining group Rio Tinto (ASX/LSE:RIO), to accelerate exploration across 1,884km² of highly prospective tenure within the Paterson Province of Western Australia (Paterson South Project) located near the Company's world-class Havieron gold-copper project1 (Havieron).
The Paterson South Project farm-in and joint venture arrangement is consistent with Greatland's Australian asset growth strategy including the Company's commitment to exploration success.
The tenements are an outstanding package, which host several underexplored anomalies which the Company considers to be the closest to a Havieron lookalike within the Paterson Province.
In addition, there has been historical delineation of gold in rock chips and copper intersected with strong correlation to a Telfer style deposit.
The expansion of Greatland's footprint and exploration activities in the Paterson Province leverages Greatland's existing presence in the region, its good standing within the Paterson community and the strong technical knowledge fostered through the discovery of Havieron.
The Paterson South Project remains relatively underexplored and is a logical fit for Greatland's existing adjacent tenure holdings.
[1] Held by the Havieron JV between Greatland (30%) and Newcrest Mining Limited (Newcrest) (70%).
Highlights
§ The eastern group of the Paterson South Project tenements host several underexplored magnetic anomalies. These targets are within Proterozoic sediments and are considered by the Company to be the closest to a Havieron lookalike within the Paterson Province
§ The western group of the Paterson South Project tenements have a geological setting which is a strong correlation to the Telfer deposit with historical delineation of gold in rock chips and copper intersected in the limited drilling undertaken to date
§ Greatland to commence drilling in 2023
§ Initial minimum commitment of A$1.1 million of expenditure and 2,000 metres of drilling before 31 December 2024
§ Farm-In: Greatland is entitled to earn up to a 75% joint venture interest in the Project Tenements under a two-stage farm-in arrangement:
- Stage 1 Farm-In: Greatland is entitled to earn a 51% joint venture interest in the Paterson South Project by incurring at least A$7.1 million of exploration expenditure and completing 7,500 metres of drilling within four years; and
- Stage 2 Farm-In: Greatland is entitled to earn an additional 24% joint venture interest in the Paterson South Project (cumulative joint venture interest of 75%) by spending at least an additional A$14 million of exploration expenditure and completing a further 17,000 metres of drilling within three years of completing the Stage 1 Farm-In.
Greatland Managing Director, Shaun Day, commented:
"The Paterson South Project tenement package is an outstanding opportunity with a number of high priority, highly prospective and heritage cleared drill targets. We expect that some of these targets can be incorporated in our 2023 drilling campaign.
These targets include underexplored anomalies which the Company considers to be the closest to a Havieron lookalike within the Paterson Province.
Other opportunities include historical delineation of gold in rock chips and copper intersected with strong correlation to a Telfer style deposit.
This tenure complements the Company's current ground position to provide a 105km contiguous holding. The addition of the Paterson South Project more than doubles our current footprint with the most prospective targets within 50km of Telfer.
Our farm-in and joint venture with Rio Tinto is consistent with our strategy of continuing to invest in exploration success, and aligns the companies responsible for the discovery of Havieron and Winu, the two biggest and most significant orebodies found within the Paterson Province since Telfer in the 1970s."
Paterson South Project farm-in and joint venture arrangement
Greatland Paterson South Pty Ltd, a wholly-owned subsidiary of the Company, has executed a long form farm-in and joint venture term sheet with Rio Tinto Exploration Pty Limited (RTX), a wholly-owned subsidiary of Rio Tinto in respect of the Paterson South Project which comprises exploration licences E45/4807, E45/4815, E45/4834, E45/5122, E45/5238, E45/5242, E45/5532, E45/5351 and E45/5576 (Project Tenements). The Paterson South Project is currently 100% beneficially held by RTX.
Under the farm-in and joint venture arrangement:
§ Up-front Payment: Greatland will make an up-front payment of A$350,000 to RTX payable in either cash or Greatland shares at Greatland's election to be paid within 30 days of execution if Greatland elects to pay in cash or within 6 months if Greatland elects to pay in shares
§ Farm-In: Greatland is entitled to earn up to a 75% joint venture interest in the Project Tenements under a two-stage farm-in arrangement:
§ Stage 1 Farm-In: Greatland is entitled to earn a 51% joint venture interest in the Paterson South Project by incurring at least A$7.1 million of exploration expenditure and completing 7,500 metres of drilling within four years; and
§ Stage 2 Farm-In: Greatland is entitled to earn an additional 24% joint venture interest in the Paterson South Project (cumulative joint venture interest of 75%) by spending at least an additional A$14 million of exploration expenditure and completing a further 17,000 metres of drilling within three years of completing the Stage 1 Farm-In.
As part of the Stage 1 Farm-In, Greatland's minimum commitment comprises A$1.1 million of exploration expenditure and 2,000 metres of drilling to be completed before 31 December 2024. Greatland is entitled to withdraw once it has met this minimum commitment.
If Greatland completes the Stage 1 Farm-In and elects to acquire a 51% joint venture interest in the Paterson South Project, an unincorporated joint venture (PSJV) will be formed between Greatland Paterson South Pty Ltd (51%) and RTX (49%). Greatland Paterson South Pty Ltd will be the manager of the PSJV. RTX is entitled, after completion of the Stage 1 Farm-In, to elect to contribute to its share of PSJV expenditure. If RTX so elects, Greatland Paterson South Pty Ltd's PSJV joint venture interest will remain at 51% and the Stage 2 Farm-In will not apply.
Outside of the farm-in periods, each PSJV participant is required to contribute to PSJV expenditure in proportion to its joint venture interest. A PSJV participant is entitled to elect not to contribute to its share of PSJV expenditure at the beginning of a budget year. If it does so, it will be diluted under a customary dilution mechanism. If a PSJV participant's joint venture interest reduces to less than 10%, its joint venture interest will be converted to a net smelter royalty (NSR) of 1.25% plus an additional 0.25% if the quarterly average gold price is above US$2,000 per ounce (CPI adjusted). The NSR is at a reduced level for production from the Strickland tenement (E45/4807) of 0.75% plus 0.125% if the quarterly average gold price is above US$2,000 per ounce (CPI adjusted) for so long as the Strickland Royalty (as defined below) applies over that tenement.
An existing 1.25% NSR applies over the Strickland tenement (E45/4807) in favour of Strickland Metals Limited (Strickland, ASX:STK), as the former holder of that tenement (Strickland Royalty). The Strickland Royalty is payable in respect of the first 420,000 ounces of gold (or gold equivalent) production from E45/4807 only. Strickland is also entitled to a pre-payment of that royalty on a decision to mine calculated based on the prevailing spot price for 42,000 ounces of gold (or gold equivalent).
Overview of the Project Tenements
Figure 1: Overview of the Paterson South Project
Eastern group of tenements
§ Budjidowns (E45/4815, 191km2) hosts several short strike length magnetic anomalies of similar size to the Havieron anomaly (which is associated with the SE Crescent's magnetic massive pyrrhotite ore), which are untested or have only single drill holes testing the anomaly. Of particular interest is the Decka target (see Figure 2), a magnetic anomaly which also sits on the same gravity gradient as Havieron and has a coincident late time airborne electromagnetic anomaly interpreted as a bedrock conductor, indicating the potential presence of pyrrhotite as distinct from the less conductive but magnetic magnetite.
Figure 2: Decka prospect location with effective drilling on RTP magnetics
§ Basel (E45/5122, 639km2) adjoins to the north of Greatland's Paterson Range East (E45/4928)2 tenement. A review of the historical drilling has identified two reverse circulation (RC) holes with +0.5g/t Au single metre assays at the Calypso prospect (see Figure 3) (CAW3-0 - 3.03g/t Au and CAW5-0 - 0.74g/t Au) likely in Permian cover and approximately 5.7km apart. These holes were originally targeted on anomalous surface sample results. Subsequent airborne magnetic and gravity surveys confirmed them as sitting on the margin of a magnetic granite. The target is prospective for intrusion related gold-copper mineralisation in the basement.
§ Wilki Lake (E45/5576, 32km2) sits over a NE trending break in the magnetic granite on a deep seated fault, approximately 8km east of and parallel to a similar structure seen at Telfer. Minimal exploration work has been conducted on the tenement, with an aeromagnetic survey completed, but limited on-ground activity. The area is considered prospective for intrusive related gold-copper mineralisation.
§ Skylar (E45/5351, 143km2) and Triangle South (E45/5532, 143km2) adjoin to the south of the Havieron (M45/1287) and Scallywag (E45/5316) tenements. They contain an anticline / syncline pair outlined by the magnetic base of the Wilki formation with Puntapunta and possibly Malu formation sediments interpreted in the core of the anticline. The tenements are considered prospective for Telfer style mineralisation.

Western group of tenements
§ Strickland (E45/4807, 424km2) is centred on the sub-cropping to shallowly buried Proterozoic, doubly plunging Paterson Dome Anticline fold. The fold is interpreted to contain Telfer Member sediments in the core. Gold mineralisation has been identified in surface sampling in the core of the NW Dome (Manuka) (Figure 4) with a peak of 2.67g/t Au and considered to be similar to Telfer mineralisation. Coherent copper mineralisation has been intersected in the Puntapunta formation on the NW margin of the SE Dome (Paterson Dome W) in shallow, 600m spaced rotary air blast drilling with a peak of 45m at 0.11% Cu from 68m to end of hole (GPW015). The mineralisation has been identified over a strike length of ~ 3km and is open to the northwest.
§ Telfer Domain (E45/4834, 147 km2) adjoins to the north of the Strickland (E45/4807) tenement. It contains similar stratigraphy and structure to that seen in the Strickland (E45/4807) tenure but appears to be under thicker cover.
§ Kaliranu (E45/5238, 57km2) overlies Proterozoic Mount Crofton Granites directly south of the Strickland (E45/4807) tenure. The granites are part of a series intruded along a 70km NE trending crustal break. The Geological Survey of Western Australia (GSWA) airborne gravity appears to show a slight magnetic upgrade where the intrusives crosscut the Paterson Dome anticline. Kaliranu (E45/5238) is considered prospective for intrusion related gold-copper style mineralisation.
§ Paterson 8 (E45/5242, 6km2) is a small tenement covering the Wilki / Puntapunta contact ~20km north of Telfer on an interpreted north - south structure considered prospective for intrusive related mineralisation.

Planned Exploration
The planned exploration programme for the financial year to June 2024 is intended to include:
§ Budjidowns (E45/4815): systematic drill testing of the Decka and Stingray targets following forward modelling of the magnetic anomalies to ensure the most effective drilling programme. Reviews of the remaining magnetic anomalies are underway to better target these anomalies;
§ Strickland (E45/4807): the Paterson Dome West and Chilly prospects will be targeted with drilling subject to heritage clearances; and
§ Basel (E45/5122): a heritage survey is planned for the Calypso prospect to enable regional scale drilling to basement utilising multi-element geochemistry both within the cover and basement to vector to source mineralisation.
Work is ongoing to identify and prioritise targets on the remainder of the Paterson South Project Tenements with testing based on their prospectivity ranking.

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 (which is the subject of a takeover by Newmont Corporation by way of a scheme of arrangement).
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. 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). Subject to a positive feasibility study and Decision to Mine, 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.

Sampling techniques |
§ Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation) § Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used § Aspects of the determination of mineralisation that are Material to the Public Report § In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information |
§ Gindalbie AirCore (AC) program Strickland 1999 (DMIRS rept A61274) § AC samples were taken at 1m intervals and laid on the ground prior to compositing a 2-3kg lab sample for each 4m or 6m interval over the full length of the hole. No intervals were re-assayed in 1m intervals § Strickland tenement rock chip samples were taken as part of a small (7 sample) reconnaissance programme in 2019 by RTX

|
Sub-sampling techniques and sample preparation |
§ If core, whether cut or sawn and whether quarter, half or all core taken. § If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry § For all sample types, the nature, quality and appropriateness of the sample preparation technique § Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples § Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling § Whether sample sizes are appropriate to the grain size of the material being sampled |
§ Gindalbie AC § All samples were submitted to ULTRATRACE Analytical Laboratories in Perth. Sample preparation comprised drying and pulverising total samples received to 80% pass -75 micron grain size § Sub sampling is reduced to a minimum by using total sample pulverisation prior to sub sampling wherever possible § The sample sizes (2-3kg) are considered appropriate for the material being sampled § Rock chip samples were submitted to ALS Laboratories in Perth. Sample preparation comprised pulverising total samples received to 80% pass -75micron grain size |
|
Quality of assay data and laboratory tests |
§ The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total § For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc § Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
§ Gindalbie AC § The samples were assayed for Au by 40gm fire assay with an aqua regia acid digest and ICPOEs and for Ag,As, Cu, Pt, Pd and Zn via aqua regia acid digest and ICPOEs. The assays are considered total rather than partial § Apart from standard laboratory check work, no information is available on QA QC procedures § The work is considered sufficient for exploration results reporting |
|
Verification of sampling and assaying |
§ The verification of significant intersections by either independent or alternative company personnel. § The use of twinned holes § Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols § Discuss any adjustment to assay data. |

|
Orientation of data in relation to geological structure |
§ Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type § If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material |
§ Drilling is oriented vertically into assumed vertical stratigraphy and is not optimal for representative sampling |
|
Sample security |
§ The measures taken to ensure sample security |
§ Sample security measures are not recorded, but assumed adequate |
|
Audits or reviews |

Mineral tenement and land tenure status |
§ Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings § The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area |
§ The tenure is subject to a land access agreement between the Western Desert Lands Aboriginal Corporation (now Jamukurnu-Yapalikurnu Aboriginal Corporation; JYAC) and Rio Tinto (in respect of E45/4815, E45/4834, E45/5122, E45/5238, E45/5242, E45/5532, E45/5351 and E45/5576) and Strickland Metals Limited (in respect of E45/4807) (pending its proposed assignment to Rio Tinto), and Greatland will undertake work, subject to the terms of these agreements Gindalbie AC § The work was carried out in what is now the Strickland tenement (E45/4807), currently beneficially held 100% by RTX. Greatland is currently farming into this tenement with the right to earn up to a 75% interest, under certain conditions. There is a 1.25% NSR on the first 420,000 ounces of production from that tenement payable to Strickland Metals Limited (as royalty holder), with a prepayment of the royalty due on a decision to mine § Areas of the tenement are subject to a temporary heritage exclusion zone which affects ~50% of the total area of the tenement. A review of this temporary exclusion zone has been agreed with JYAC |
|
Exploration done by other parties |
§ Acknowledgment and appraisal of exploration by other parties |
E45/4807 (Strickland) § Previous work including surface sampling wide spread rotary air blast, diamond drilling and aeromagnetic surveys were all carried out prior to the Gindalbie AC drilling in 1999 principally by Newmont and BHP in the 1980s and 1990s. This regional work identified several gold and copper targets including the Paterson dome west anomalism were followed up by Gindalbie § A complete summary of previous exploration across the tenement package is included in Appendix 4 |
|
Geology |
§ Deposit type, geological setting and style of mineralisation |
§ Exploration is for intrusion related and orogenic, structurally controlled Au-Cu deposits similar to Telfer, Havieron and Winu, all located in Neo-Proterozoic Yeneena Group sediments of the Paterson Province, Western Australia |
|
Drill hole Information |
§ A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: § easting and northing of the drill hole collar § elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar § dip and azimuth of the hole § down hole length and interception depth § hole length § If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case |
§ Drillhole collar tables are supplied for the 1999 Gindalbie AC program on the Strickland tenement and the RC drilling on Basel in Appendix 3. |
|
Data aggregation methods |
§ In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated § Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail § The assumptions used for any reporting of metal equivalent values should be clearly stated |
§ No economically significant results have been reported, and no data aggregation methods have been applied § Where anomalous results are quoted (Table 2) the samples have been selected as follows: § Au >0.1ppm; or § Ag >2ppm; or § Cu >200ppm; or § Bi >1ppm; or § Pb >200ppm; or § Zn >1000ppm
|
|
Relationship between mineralisation widths and intercept lengths |
§ These relationships are particularly important in the reporting of Exploration Results § If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported § If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known') |
§ No economically significant results are reported, and there is no known relationship between reported widths and the geometry of any mineralisation § All intercepts are reported downhole as true width is not known |
|
Diagrams |
§ Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views |
§ Maps are provided in Figures 1 to 4. No significant discovery is reported |
|
Balanced reporting |
§ Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results |
§ The reporting is considered balanced |
|
Other substantive exploration data |
§ Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances |
§ No other substantive exploration data other than that provided in the Figures |
|
Further work |
§ The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling) § Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive |
§ Further work is outlined in the Planned Exploration section of the main body of the text |
APPENDIX 2
Tenure Status
The Paterson South Project Tenements have been relatively underexplored to date due to access challenges and concealing cover sediments. This may have some bearing on the ability to retain some tenure when renewals are due. The tenements will benefit from the logistical benefits that proximity to Havieron will provide.
There are three tenements (Telfer Domain (E45/4834), Budjidowns (E45/4815) and Strickland (E45/4807)) that are due for compulsory surrender in respect of 40% of the tenement blocks this year, with the surrender having already been submitted for Telfer Domain (E45/4834). The Company is of the view that the 40% reductions for these tenements will not impact their prospective portions.
An extension of term application has been submitted for Basel (E45/5122).
