The 100%-owned Julimar Nickel-Copper-PGE Project is located ~70km north-east of Perth. The Project is favourably located, with world-class road, rail, port and high-voltage power infrastructure nearby, plus access to a significant 'drive-in / drive-out' mining workforce in Perth surrounds.
The Julimar Project was stacked in early 2018 as part of Chalice's global search for high-potential nickel sulphide exploration opportunities.
Chalice discovered the Gonneville deposit in the very first drill hole at the project in March 2020, intersecting shallow high-grade PGE-nickel-copper-cobalt-gold sulphide mineralisation. Gonneville is located on private farmland at the southern end of the interpreted >26km long Julimar Complex.
The significant Gonneville discovery has defined the new West Yilgarn Ni-Cu-PGE Province, an almost entirely unexplored mineral province which is interpreted to extend for ~1,200km along the western margin of the Yilgarn Craton. Chalice holds an unrivalled >8,000km2 land position in this exciting new area and is leveraging its competitive ‘first mover’ advantage.

Chalice has defined a tier-1 scale maiden mineral resource estimate for Gonneville, now the largest nickel sulphide discovery worldwide since 20001, and the largest PGE discovery in Australian history – demonstrating the potential for Julimar to become a strategic, long-life ‘green metals’ asset.
Maiden Indicated and Inferred Mineral Resource Estimate - Gonneville Deposit:
- 330Mt @ 0.94g/t Pd+Pt+Au (3E), 0.16% Ni, 0.10% Cu, 0.016% Co (~0.58% NiEq or ~1.6g/t PdEq)
- 10Moz 3E, 530kt Ni, 330kt Cu and 53kt Co contained
- Equivalent to ~1.9Mt NiEq or ~17Moz PdEq contained
The pit-constrained Resource includes a significant higher-grade sulphide component above a 0.6% NiEq cut-off grade, starting from a depth of ~30m:
- 74Mt @ 1.8g/t 3E, 0.22% Ni, 0.21% Cu, 0.020% Co (~1.0% NiEq or ~2.8g/t PdEq);
- Containing 4.2Moz 3E, 160kt Ni, 150kt Cu, 15kt Co (~740kt NiEq or ~6.6Moz PdEq);
View the Mineral Resource Tables and JORC Tables. For further details, please refer to the complete Gonneville Maiden Resource Estimate ASX Announcement.
The Resource includes a significant high-grade sulphide component, affording the project significant optionality in development and the potential to materially enhance project economics in the initial years of operations.
The Gonneville Resource is interpreted to cover just ~7% of the Julimar Complex strike length. As such the project is considered highly prospective for further orthomagmatic Ni-Cu-PGE discoveries.
Recent step-out drilling at the north-western limit of the Gonneville deposit has intersected a new zone of shallow high-grade mineralisation.
This discovery is considered significant because the new zone is located immediately south of the ~6.5km long Hartog AEM anomaly (within the Julimar State Forest). In addition, it confirms that there are other mineralised intrusions in the area that have no EM response. As such, it is interpreted that the Hartog AEM anomaly may stem from the northern extension of this mineralised zone, which in turn may represent the very southern extent of an entirely new intrusion (Hartog).
The first-ever, low-impact diamond drilling commenced at Hartog Target in late January 2022.
Chalice’s exploration drilling in the Julimar State Forest is strictly governed by the Stage 2 Conservation Management Plan (CMP), developed in consultation with the Department of Biodiversity Conservation and Attractions (DBCA) and approved by the WA State Government on 29 December 2021.

Chalice’s Julimar Project strategy is to concurrently advance studies for an initial mining development on private farmland and to define the full extent of mineralisation along the >26km long Julimar Complex.
Ongoing and planned activities at Julimar include:
- Step-out drilling (farmland) – Step-out diamond drilling on a nominal ~80m spacing is expected to continue until ~Q1 2022, subject to results. Step-out drilling is targeting the extension of high-grade (>0.6 NiEq) zones.
- Infill drilling (farmland) – The northern portion of the Gonneville Resource is currently classified as Inferred and additional infill drilling is targeting conversion of the shallow (<250m deep) portion into the higher-confidence Indicated category.
- Reconnaissance drilling at the Torres-Jansz and Baudin targets at the northern end of the Julimar Complex – First-pass AC drilling on private farmland will commence in the coming weeks.
- Geotechnical, metallurgical, hydrogeological and infrastructure drilling (Gonneville) – AC/RC/diamond drilling to support studies for Gonneville will commence once resource drilling is complete and will continue through Q1 2022.
- Metallurgical testwork (Gonneville) – ongoing testwork is now focused on optimisation of disseminated sulphide performance and continuing leach testwork on oxide composites. Investigation into further bulk concentrate enrichment alternatives has commenced for the disseminated sulphide mineralisation as part of the recent $2.9M grant from the Australian Government’s Co-operative Research Centre Projects (CRC-P) Program. Initial waste rock and tailings characterisation testwork continues.
- Studies (Gonneville) – Work is underway to support studies for the project, which will assess potential mine development scenarios for the Gonneville Deposit. The Company anticipates that a Scoping Study for the initial stage of development at Gonneville will be completed in Q2 2022.
- Low-impact reconnaissance drilling at the Hartog-Baudin Targets within the Julimar State Forest – First-pass low-impact drilling utilising small track-mounted diamond rigs has commenced on existing access tracks. A total of ~70 drill sites are planned across the ~10km strike length, with the ability to drill multiple angled holes at each site. No mechanised vegetation clearance is required to complete this first pass of drilling.
