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 >740km²


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 staked 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 >30km 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 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.

Updated Indicated and Inferred Mineral Resource Estimate - Gonneville Deposit:

  • 350Mt @ 0.94g/t Pd+Pt+Au (3E), 0.16% Ni, 0.10% Cu, 0.015% Co (~0.58% NiEq or ~1.8g/t PdEq)
  • 11Moz 3E, 560kt Ni, 360kt Cu and 54kt Co contained
  • Equivalent to ~2.0Mt NiEq or ~20Moz PdEq contained

The higher-grade sulphide component of the Resource (>0.6%NiEq cut-off in-pit plus underground) has also increased to:

  • 82Mt @ 1.7g/t 3E, 0.21% Ni, 0.20% Cu, 0.020% Co (~1.0% NiEq or ~2.9g/t PdEq);
  • Containing 4.5Moz 3E, 180kt Ni, 170kt Cu, 16kt Co (~790kt NiEq or ~7.7Moz PdEq);


For further details, including the Mineral Resource Tables and JORC Tables, please refer to the Updated Gonneville Mineral Resource announcement, dated 8 July 2022. 

The Resource includes a significant higher-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 Gonnville Resources in interpreted to cover just ~7% of the interpreted >30km long Julimar Complex strike length with initial large scale exploration activities underway over the remaining strike length. As such the region is considered highly prospective for further orthomagmatic Ni-Cu-PGE discoveries.

Chalice's ongoing exploration drilling program in the Julimar State Forest is utilising small footprint diamond drill rigs and does not involve any mechanised clearing of vegetation or excavation .  Comprehensive flora, fauna and cultural heritage surveys and monitoring are being used according to industry best practice. The low-impact program is strictly governed by a Conservation Management Plan approved by the WA Government in late 2021.

The Company continues to progress development studies for the Gonneville Deposit in parallel to testing the overall scale of the Gonneville mineral system and initial exploration activities across the >30km long Julimar Complex.

The following activities are ongoing or planned at the Project:

  • Exploration drilling at the Hartog-Dampier Targets within the Julimar State Forest - four diamond drill rigs are currently operational and expected to continue for the foreseeable future. Existing approvals allow multiple holes to be drilled from each of the ~70 planned sites.
  • Moving Loop Electromagnetic (MLEM) and Down-hole EM surveys are continuing across the Julimar Complex.
  • Resource definition and exploration RC/diamond drilling at the Gonneville Deposit - three rigs are operated, largely focused on wide-spaced extensional exploration drilling which is expected to continue for the foreseeable future, subject to results. 
  • Mine development studies to support a Scoping Study for the initial development stage of the Gonneville Deposit.
  • Baseline surveys of ground water, surface water, flora, fauna and dieback, as part of a long-term baseline and monitoring program to support engineering studies and environmental assessments (ongoing).
