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 a mafic-ultramafic layered intrusive complex at Julimar based on high resolution regional magnetics.
The large complex is interpreted to be ~26km long and ~7km wide and is considered highly prospective for nickel, copper and platinum group elements. However, it has never been explored for these metals.
Chalice is targeting high-grade nickel-copper-PGE discoveries and commenced a systematic, regional-scale greenfield exploration program in mid-2019 upon gaining access, initially in the southern portion of the Project on private land. 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 ~2km x 0.5km discrete magnetic anomaly interpreted as a potential feeder zone located near the southern extent of the intrusive complex. An initial RC drill program commenced in Q1 2020.
A maiden 4-hole Reverse Circulation (RC) drill program commenced at Julimar in early March 2020 to test these three high-conductance ground MLEM targets, which appear to be associated with the margins of a discrete ‘lens-shaped’ magnetic anomaly.
The first RC drill hole, JRC001, was drilled to test MLEM Conductor ‘E’, located along the south-west margin of the magnetic anomaly, and returned a significant intersection in fresh rock of:
- 19m @ 2.59% Ni, 1.04% Cu, 8.37g/t Pd and 1.11g/t Pt (down-hole width), including:
- A massive sulphide zone of 13m @ 3.15% Ni, 1.19% Cu, 8.85g/t Pd and 1.09g/t Pt from 48m; and,
- A matrix/stringer sulphide zone of 6m @ 1.39% Ni, 0.72% Cu, 7.33 g/t Pd and 1.16g/t Pt from 61m.
- The above massive and matrix/stringer sulphide zones are within a broader zone of disseminated sulphides containing high-grade Pd and elevated Pt:
- 25m @ 2.02% Ni, 0.88% Cu, 8.50g/t Pd and 0.91g/t Pt from 46m, reported above a 1.0g/t Pd cut-off grade.
Cobalt and other PGE assays are pending. The massive sulphide zone coincides with the interpreted position of Conductor ‘E’, indicating that MLEM has been successful and highly effective at targeting shallow sulphides.
The true width of the mineralised intervals are not known, however MLEM Conductor ‘E’ is modelled as a steep westerly-dipping plate, indicating an interpreted near-true width intersection (Figure 3).
The MLEM plate has an estimated strike length of ~140m. However, due to the strength of the conductor which masks any response at depth, it has not been possible to model the true depth extent. Therefore, the conductor is considered poorly constrained and the zone is open in all directions.
