Julimar Nickel-Copper-PGE Project

Location Avon Region, Western Australia
Development Stage Advanced Exploration - new discovery in March 2020
Acquired Staked in 2018 and subsequently expanded
Ownership 100%
Project Area >2,000km²


The 100%-owned Julimar Nickel-Copper-PGE Project is located ~70km north-east of Perth on private farmland and State Forest. The Project has direct access to major highway, rail, power and port infrastructure in one of the world’s most attractive mining jurisdictions – Western Australia.

Julimar is Australia’s first major palladium discovery, and is fast emerging as a very large, strategic deposit of critical, 'green metals'. 

Chalice made a significant greenfield  PGE-Ni-Cu-Au discovery at the Project (the Gonneville Discovery) in March 2020. The major greenfield discovery was made in a largely unexplored area and defined the new West Yilgarn Ni-Cu-PGE Province in WA. 

Chalice interpreted the possible presence of a mafic-ultramafic layered intrusive complex (the ‘Julimar Complex’) based on high-resolution airborne magnetics. The Julimar Complex is interpreted to extend over ~26km of strike and is confirmed to be highly prospective for nickel, copper and platinum group elements (PGE).

The Gonneville Discovery is hosted within the ~1.8m x >0.9km Gonnevile Intrusion, a layered mafic-ultramafic 'sill', with a moderate westerly dip and gentle northerly plunge. The intrusion hosts several styles of PGE-Ni-Cu-Co-Au sulphide mineralisation, with eleven high-grade zones defined to date (>1g/t Pd cut-off), which are surrounded by widespread disseminated sulphide mineralisation. 

Weathering at Gonneville extends down to ~30-40m below surface and a well-developed saprolite (oxide) profile contains elevated PGE-Au grades from near surface to a depth of ~25m (top of fresh rock). 

A maiden Mineral Resource Estimate for Gonneville is expected in late Q3 2021, and Chalice has commenced early stage economic studies to support a potential mining project development. 

Early stage metallurgical testwork completed to date on selected high-grade and disseminated sulphide mineralisation samples from Gonneville has returned promising flotation results, giving initial encouragement that the sulphide-hosted mineralisation at Gonneville will be amendable to conventional flotation under standard conditions. 

Tests completed on a composite of oxide mineralisation samples has also returned promising results, with the extraction of palladium and gold achieved through oxidative leaching under standard conditions.

Initial reconnaissance exploration around Julimar has determined that Gonneville appears to be part of a ~26km long intrusive complex (the Julimar Complex). Several highly prospective regional EM/gravity/soil targets have been defined across the complex and are yet to be drill tested.

Chalice is continuing the resource definition drill program and early studies at the ~1.8km x >0.9km Gonneville Intrusion in parallel with the initial exploration activities within the Julimar State Forest to the north. 

Ongoing and planned activities at Julimar include:


  • Resource definition drilling (Gonneville) – The RC/diamond drill program aims to define Mineral Resources predominantly in the Indicated category to a nominal ~200m below surface (deeper in high-grade zones), which is expected to be achieved with a 40m spaced drill pattern. Areas deeper than ~200m below surface are being drilled on a wider spaced pattern, as determined by preliminary pit-shell modelling, with the Mineral Resources expected to be reported predominantly in the Inferred category. Due to the continued growth of mineralised zones and the required drilling, the Company anticipates its maiden Mineral Resource Estimate will be released in late Q3 2021.
  • Metallurgical testwork (Gonneville)- variability flotation testwork on sulphide zone composites and leach testwork on oxide zone composites continues. New high-grade and disseminated sulphide composites have been complied for the next phase of testwork. 
  • Mining studies (Gonneville) - hydrology, hydrogeology, waste rock characterisation and initial infrastructure studies have commenced. The Company has appointed a Study Manager for the Project and anticipates that a scoping study will be released in early 2022.
  • Marketing studies (Gonneville) - preliminary discussions with various potential offtake partners have commenced, to determine indicative commercial terms for potential intermediate concentrate products.
  • Geochemistry and Geochronology - the Company has engaged the Geological Survey of WA (GSWA) and a specialist consultant to conduct initial geochemical analysis and metallogenesis studies. This work aims to improve our geological and mineralogical understanding of the discovery and enhance our targeting capability as we search for similar discoveries across our large landholding in the West Yilgarn Ni-Cu-PGE Province.
  • Reconnaissance exploration and environment surveys within the Julimar State Forest - Flora and fauna surveys have been completed at the Hartog Target. Following the completion of ground gravity survey and reconnaissance soil sampling across the entire Julimar Complex, planning is now underway for initial first-pass MLEM lines and infill soil sampling.

    Approval is being sought from the relevant Western Australia State Government department to allow first-pass drill testing within the Julimar State Forest. This initial phase of drilling will be completed with small, track-mounted diamond drill rigs to minimise ground disturbance and eliminate the need for vegetation clearance.

    Drilling is expected to commence at the Hartog Target in late Q3 2021, subject to access approval.
