Greatland Gold plc

("Greatland" or "the Company")


Greatland awarded a drilling grant for Paterson province exploration project


Greatland receives a grant of up to A$200,000 (£115,000)

under the Western Australian Government's Exploration Incentive Scheme


Grant to be used to co-fund exploration at Greatland's 100% owned Rudall licence,

located 20km southeast of the Havieron gold-copper resource



Greatland Gold plc (AIM:GGP), a mining development and exploration company with a focus on precious and base metals, is pleased to announce it has been awarded a grant from the Western Australian Government to co-fund exploration drilling and mobilisation costs at its 100% owned Rudall licence in the Paterson province. 


The grant awarded is the result of a successful application under the Exploration Incentive Scheme ("EIS").  Greatland is eligible to receive a grant up to A$200,000 (£115,000) to co-fund drilling and mobilisation costs, within 12 months of the grant.


Shaun Day, Managing Director of Greatland Gold plc, commented: "The drilling grant for the Rudall licence will accelerate our programme to test targets in this area of the Paterson. Testing of priority targets delivers the opportunity to unlock the exploration option value of the portfolio."


About Rudall

The Rudall licence covers an area of approximately 65 square kilometres approximately 20km south-southeast of Greatland's Havieron gold-copper resource.  The licence is considered to be prospective for Havieron and Telfer style gold/copper occurrences.


Greatland has completed geophysical modelling to enhance preliminary targets identified at the Rudall licence, including the Ramses magnetic anomaly.  The modelling suggests the depth to top of the magnetic anomaly is approximately 700m below surface.


Further geophysical survey work is being planned this year to refine the Ramses anomaly before an exploration drill program is undertaken, utilising the EIS grant to co-fund the drilling component of the 2022 exploration work programme.

About the Exploration Incentive Scheme

The Co-funded Government and Industry Drilling Program is being funded by the Western Australian State Government, to provide a stimulus to geoscience exploration and contribute to the economic development of regional areas of Western Australia. Geoscience exploration includes mineral, oil and gas, and geothermal exploration with drilling to be undertaken in underexplored areas.  The program is administered by the Western Australian Department of Mines, Industry Regulation and Safety.

Notes for Editors:


Greatland Gold plc (AIM:GGP) is a mining development and exploration company with a focus on precious and base metals. The Company's flagship asset is the world-class Havieron gold-copper deposit in the Paterson region of Western Australia, discovered by Greatland and presently under development in Joint Venture with Newcrest Mining Ltd.


Havieron is located approximately 45km east of Newcrest's Telfer gold mine and, subject to positive decision to mine, will leverage the existing infrastructure and processing plant to significantly reduce the project's capital expenditure and carbon impact for a low-cost pathway to development. An extensive growth drilling programme is presently underway at Havieron with a maiden Pre-Feasibility Study released on the South-East crescent on 12 October 2021. Construction of the box cut and decline to develop the Havieron deposit commenced in February 2021.


Greatland has a proven track record of discovery and exploration success. It is pursuing the next generation of tier-one mineral deposits by applying advanced exploration techniques in under-explored regions. The Company is focused on safe, low-risk jurisdictions and is strategically positioned in the highly prospective Paterson region. Greatland has a total six projects across Australia with a focus on becoming a multi-commodity mining company of significant scale.

JORC Code explanation


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.
