The Ardea WA tenure represents a large strategic land holding in one of Australia’s premier nickel sulphide and gold provinces. Ardea has several additional project mineralisation styles outside of the GNCP goethite. In addition to the other laterite hosted nickel-cobalt opportunities, Ardea’s tenure also hosts significant “greenfields” nickel sulphide and/or gold mineralisation.
Perrinvale nickel sulphide prospect
Perrinvale is located approximately 100km west of Leonora. The Ardea exploration model is based on recent nickel sulphide discoveries immediately west of Perrinvale made by St George Mining. Regional magnetic data highlights that the feature which hosts the St George Mining nickel sulphide discoveries within the Cathedrals Belt, has an east-northeast strike and extends into Perrinvale. At Perrinvale, this prospective trend is overlain by transported cover, requiring geophysical methods such as moving loop Electro Magnetic (MLEM) surveys for exploration targeting.
MLEM surveys have been completed by Ardea over three separate zones at Perrinvale with a consultant’s field report received during the December 2019 Quarter which recommended follow-up exploration including shallow aircore drilling beneath transported cover to determine basement geology and the geochemical signature associated with the EM anomalies defined. Surface EM surveys were recommended over the areas not covered by the initial trial survey.
Ardea has non-gold mineral rights for the Bulong tenements, located approximately 30km east of the City of Kalgoorlie Boulder.
Ardea's focus on the Bulong tenements has been on high grade laterite hosted nickel-cobalt mineralisation (54.1Mt at 0.88% Ni and 0.05% Co, for contained metal of 476.1kt nickel and 28.8kt cobalt) as part of the KNP resource base.
Ardea works with Kalgoorlie-Boulder prospectors who have been recovering alluvial, eluvial and primary gold in the area which is assisting with Ardea target generation and furthering the understanding of the controls on Bulong gold mineralisation.
In addition to the significant nickel-cobalt resources hosted at Bulong, 36 exploration targets have been defined. These range from gold, PGEs and base metals (nickel, copper, lead and zinc).
Limited historic nickel-cobalt laterite drill holes have been located over some of the targets and a search for the historic pulps within Ardea’s West Kalgoorlie sample archive facilities has been completed and samples submitted for multi-element assay. This is a low impact and much cheaper form of exploration, as it removes the need to redrill holes.
Mt Zephyr-Darlot East Red 5 Joint Venture
In November 2020, Ardea executed a Farm-in Joint Venture Agreement with ASX-listed gold producer Red 5 Limited (ASX: RED, Red 5). Red 5 can earn up to an 80% interest in Ardea’s Mt Zephyr and Darlot East Gold Projects, both located in close proximity to the Red 5 Darlot Gold Mine. Under the terms of the Agreement, Red 5, through its 100%-owned subsidiary, Darlot Mining Company Pty Ltd (Darlot), has executed a Farm-in Joint Venture Agreement (Agreement) with Ardea Exploration Pty Ltd, a wholly-owned subsidiary of Ardea Resources Ltd, over the Mt Zephyr and Darlot East Gold Projects in Western Australia.

Mt Zephyr contains both primary gold and nickel mineralisation and encapsulates more than two thirds of an underexplored greenstone belt called Celia Lineament. The area east of the Celia Lineament is considered highly prospective for the following reasons:
- All historic gold workings east of lineament
- Mt Windarra nickel sulphide stratigraphy
- Jupiter, Wallaby granitoid-hosted gold to the east of the lineament further south
- Along structure from Mt Morgans, Lake Roe gold deposits
- Ardea are the first to test the new geological setting concepts
- First pass drill programs completed
- Gold at Gale, Dunn’s North, Dunn’s Line and Paul’s Find
- Ni-Cu sulphides (+ gold) at Jones Area A
- First-pass, wide-spaced (160mx160m) drilling confirms granite hosted gold mineralisation, at Gale
