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

LOCATION

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 OPPORTUNITY

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.

A recently completed airborne electromagnetic (AEM) survey over granted tenure has identified three new large EM anomalies (Hartog, Baudin and Jansz). The new Hartog EM Anomaly extends ~6.5km beyond the northern limit of drilling at the ~1.6km x 0.8km Gonneville Intrusion, further highlighting the  district-scale Ni-Cu-PGE potential of the Complex.

Chalice has also 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 an exceptional new PGE-nickel-copper-cobalt discovery within a completely new province, just an hour's drive from Perth, Western Australia

EXPLORATION

Chalice commenced a systematic, greenfield exploration program in mid-2019 in the southern portion of the Project, on private land, 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 mineralisation at the newly named Gonneville Intrusion. 

Four high-grade massive / matrix / heavily disseminated sulphide zones have been intersected to date, which are up to ~30m wide and have been defined over a ~400m x ~350m area. The zones typically have a grade range of 3-15g/t PGEs, 0-1.2g/t Au, 0.5-3.3% Ni, 0.4-4.5% Cu and 0.03-0.27% Co. 

Broad intervals of PGE mineralisation have been confirmed in all holes drilled to date at the Intrusion and disseminated sulphides (trace to 3% on average) have been identified down to ~450m below surface. Disseminated sulphide zones intersected to date typically have a grade range of 0.5-2.0g/t PGEs, 0.1-0.2% Ni, 0.05-0.15% Cu and 0.01-0.03% 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 (typically ranging from 1.2-4.5g/t PGEs) from near surface to a depth of ~25m

FORWARD 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:

 

  • 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 ~0.8km Gonneville Intrusion to provide sectional east-west coverage and to define the extent of the mineralised system. In high-grade target areas, RC drilling continues on a nominal 80m x 80m step-out grid.
     
  • Diamond drilling – two diamond drill rigs continue to step-out from known high-grade zones (on a nominal 80m x 80m grid) and test new DHEM targets. 
     
  • 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 all diamond holes and selected RC holes. It is important to note the lack of an EM target does not preclude the presence of high-grade mineralisation.
     
  • Metallurgical testwork – a preliminary metallurgical testwork program is underway on four ore types – massive, matrix, disseminated and oxide.
