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 was staked in early 2018 and 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.



The Project was staked as part of Chalice's global search for high-potential nickel sulphide exploration opportunities. Chalice interpreted the possible presence of an unrecognised layered mafic-ultramafic intrusive complex at Julimar based on high resolution regional magnetics. 

The large complex is interpreted to be ~26km long and has been confirmed as highly prospective for nickel, copper and platinum group elements (PGE's). Prior to Chalice, the area had never been explored for these metals, and geological mapping of the area was limited due to extensive transported cover.

Chalice interpreted two potential 'feeder' zones within the Julimar Complex as initial areas of interest, one situated at the southern end of the complex on private farmland (the Gonneville Intrusion) and the other situated mid-way along the complex within the Julimar State Forest. Exploration activities to date have been confined to private land only, however the Minister for Environment has recently approved consent to initial non-ground disturbing activities within the Julimar State Forest under an approved Stage 1 Conservation Management Plan (CMP).

The recent discoveries by Chalice confirm Julimar is an exceptional PGE-nickel-copper-cobalt-gold discovery within a completely new mineral province in Western Australia


Chalice commenced a systematic, greenfield exploration program in mid-2019 in the southern portion of the Project, on private farmland, targeting high-grade nickel, copper and PGE’s. 

An initial RC drill program commenced in Q1 2020 and resulted in the discovery of high-grade PGE-nickel-copper-cobalt-gold mineralisation at the newly named Gonneville Intrusion. 

Seven high-grade massive / matrix / heavily disseminated sulphide zones (G1-7) have been defined to date over the southern end of the intrusion. The discrete high-grade PGE-Ni-Cu-Co- +/- Au zones comprise sulphide-rich accumulations (10-100% sulphide, defined by >1g/t Pd cut-off) and typically have a grade range of 3-15g/t PGE+Au, 0.5-3.3% Ni, 0.4-4.5% Cu and 0.03-0.27% Co. 

The intrusion also hosts widespread disseminated PGE-Ni-Cu-Co mineralisation (trace to 3% on average) surrounding the high-grade zones, which typically has a grade range of 0.5-2.0g/t PGE, 0.1-0.2% Ni, 0.05-0.15% Cu and 0.01-0.03% Co. 

Weathering extends down to ~30-40m below surface and a well-developed saprolite (oxide) profile after serpentinite contains elevated PGE-Au grades (typically ranging from 1.2-4.5g/t PGE+Au) from near surface to a depth of ~25m.

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

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

An airborne electromagnetic (EM) survey was completed in September 2020 over the entire Julimar Complex. Three new large EM anomalies were identified – Hartog, Baudin and Jansz. The Hartog EM Anomaly extends ~6.5km directly north of the Gonneville Intrusion into the Julimar State Forest. Initial exploration activities within the Julimar State Forest are due to commence in early Q1 2021. These low-impact exploration activities will have negligible impact on vegetation, fauna or recreational activities within the area, and will be governed by an approved Conservation Management Plan.

Chalice is continuing its approach of simultaneously exploring and evaluating the zones of high-grade PGE-Ni-Cu-Co+/-Au mineralisation and the extensive PGE-Ni-Cu zones associated with disseminated sulphides within the ~1.6km x 0.8km Gonneville Intrusion. 

Ongoing and planned activities at Julimar include:


  • Resource definition drilling – a ~70,000m RC/diamond drill program is underway with 3 RC and 2 diamond rigs. Drilling is initially being undertaken on an 80m x 80m spaced grid over the high-grade areas, with infill then to a 40m x 40m grid. This 40m spacing is expected to be sufficient to define Mineral Resources in the indicated category.
  • EM Geophysics (DHEM and ground EM) – DHEM continues to play a key role in identifying potential high-grade targets for follow-up drilling and will be completed on selected holes and in areas of wide-spaced drilling. It is important to note the lack of an EM target does not preclude the presence of high-grade mineralisation, based on drill results received to date.
  • Metallurgical testwork – Further sulphide flotation and oxide leach testwork is underway on 200kg of composite metallurgical samples, compiled from various mineralisation styles within the intrusion.
  • Geochemistry and Geochronology – the Company has engaged the Geological Survey of WA (GSWA) and a consultant specialist to conduct initial geochemical analysis and metallogenesis studies. This work aims to improve our geological and mineralogical understanding of the discovery and enhance our internal targeting capability as we search for similar discoveries across our large land holding in the West Yilgarn Ni-Cu-PGE Province. 
  • Greater Julimar Complex exploration – the majority of the ~26km long Julimar Complex is interpreted to lie within the State Forest and is yet to be explored. The Company has recently received approval to conduct non-ground disturbing exploration activities within the area, due to commence in early Q1 2021. The primary purpose of this first phase of activities is to effectively screen large areas with minimal impact. Exploration activities will have negligible impact on vegetation, fauna or recreational activities.
