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 early Q4 2021, and Chalice has commenced early-stage studies to support a potential mining project development.

Early stage metallurgical testwork completed to date on selected 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. 

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's Julimar Project strategy remains focused on the high-grade mineralisation at Gonneville (as the potential site for an initial mine development) as well as the exploration potential of the ~26km long Julimar Complex.

Ongoing and planned activities at Julimar include:


  • Resource definition drilling (Gonneville) – The ongoing 7-rig RC/diamond drill program aims to define mineral resources predominantly in the Indicated category to a nominal depth of ~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, with the mineral resource expected to be reported predominantly in the Inferred category. The Company now anticipates its maiden mineral resource estimate will be released in early Q4 2021, subject to lab turnaround constraints.
  • Metallurgical testwork (Gonneville)- A dedicated Metallurgy Manager for the project has recently been appointed. Variability flotation testwork on sulphide zone composites and leach testwork on oxide zone composites continues. Bulk flotation testwork on disseminated sulphide composites has also commenced. 
  • Studies (Gonneville) - Mining engineering, hydrology, hydrogeology, waste rock characterisation and initial infrastructure studies will commence shortly. The Company anticipates that a scoping study for the initial; stage of development will be released in H1 2022.
  • Reconnaissance exploration and surveys within the Julimar State Forest - Infill soil sampling and follow-up Moving Loop EM surveys are planned at the Jansz and Drummond Targets within the Julimar State Forest and on private farmland. Heritage surveys and confirmatory spring flora surveys are planned in the Julimar State Forest as soon as seasonal conditions permit, which is anticipated in August-September 2021.
