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 land 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 Julimar 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 identified two highly prospective potential 'feeder' zones within the Complex as initial areas of interest - one located at the southern end of private land and one located mid-way along the complex within the Julimar State Forest. Exploration activities have initially focussed on private land, and the approval process to gain access to the State Forest is underway. 


The recent discoveries by Chalice confirm Julimar is a significant nickel-palladium discovery within a new Ni-Cu-PGE province, just an hour's drive from Perth, Western Australia. 

Julimar Project - 3D Model - June 2020

Watch the 3D Model of the Gonneville Intrusive here.


Chalice commenced a systematic, greenfield exploration program in mid-2019 targeting high-grade Ni-Cu-PGEs. This included 200m-spaced Moving Loop Electromagnetic (MLEM) with selective 100m infill lines, targeted soil geochemistry over high-priority MLEM conductors, and geological mapping which failed to identify any bedrock exposures over the area of interest.

Two MLEM conductors were shown to be associated with anomalous nickel-in-soils and preferentially located along the margins of a discrete magnetic anomaly (the potential southern feeder zone, subsequently named the Gonneville Intrusion).

An initial RC drill program commenced in Q1 2020 at the Gonneville Intrusion and resulted in the discovery of shallow, high-grade nickel copper-cobalt-PGE mineralisation in the very first drill hole.

Drilling to date has established the Intrusive hosts widespread zones of PGE mineralisation as well as several wide zones of high-grade PGE-Ni-Cu. The significant discovery established the region as a new Ni-Cu-PGE province.

The Gonneville Intrusion is modelled as a ~1.6km long x ~0.7km wide chonolith (irregular shaped intrusive body) - a favourable geometry for large-scale magmatic sulphide deposits globally including Jinchuan in China and Kabanga in Tanzania.

High-grade massive / matrix sulphide zones intersected to date are up to ~30m wide and have been defined over a 200m x 100m area, which remains wide-open. The zones have a grade range of 3-12g/t PGEs, 0.5-3.3% Ni, 0.4-1.2% Cu and 0.03-0.18% Co.

Broad intervals of PGE mineralisation have been confirmed in all holes drilled to date at the Intrusive and disseminated sulphides (trace to 3% on average) have been identified down to ~450m below surface.

Disseminated sulphide zones intersected to date have a grade range of 0.5-1.1g/t PGEs, 0.1-0.2% Ni, 0.05-0.15% Cu and <0.05% Co. In general, metal content appears to show a positive correlation with sulphur content and levels of potentially deleterious elements (arsenic, cadmium, selenium) are all low.

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

Chalice is continuing its approach of simultaneously exploring and evaluating the extensive high-grade and low-grade PGE-Ni-Cu zones within the large-scale Gonneville Intrusion.

The Company is aiming to define a preliminary maiden Mineral Resource Estimate by mid-2021, which will be used in subsequent preliminary economic modelling.

Ongoing and planned activities at Julimar include:

·         Access approvals – the approval process to conduct non-ground disturbing exploration activities within the Julimar State Forest is underway.

·         EM Geophysics (DHEM and ground EM) DHEM will continue to play a key role in identifying potential high-grade targets for follow-up drilling and will be completed on all diamond holes and selective RC holes. It is important to note the lack of an EM target does not preclude the presence of high-grade mineralisation as evidenced by recent intercepts.

·         RC drilling – a ~20,000m Phase 2 RC drill program is underway utilising two rigs. Drilling is being undertaken on a 200m x 80m spaced grid over the ~1.6km x ~0.7km Gonneville Intrusion to provide sectional east-west coverage and, once approved, to test the extension of the G1 and G2 Zones to the south, where the Company is awaiting permit approval.

·         Diamond drilling will continue to step-out along the matrix sulphide zones and test new DHEM targets. The current hole, JD008, is being drilled ~80m north of JD003, targeting the northern extension of the G2 Zone.

·         Metallurgical testwork – a preliminary metallurgical testwork program is underway on four ore types – massive, matrix, disseminated and oxide.
