Chalice Mining’s (ASX:CHN) ground-breaking Julimar platinum group elements (PGE)-nickel-copper-cobalt discovery in WA is looking even bigger with drilling defining four new shallow, high-grade zones and extending existing zones.

Julimar has been a gamechanger for Chalice since March 2020 when its very first hole returned a 19m intersection grading 8.4 grams per tonne (g/t) palladium, 2.6 per cent nickel and 1 per cent copper.

The company’s continued drilling has now discovered four new zones – G8 to G11 – that could enhance future project economics.

Both G8 and G9 have strike lengths of more than 350m along with a dip extent of up to 250m while being wide open.

G10 has a strike length of more than 400m with a 300m dip extent and is open north along strike and downdip while G11 has a strike of more than 1,000m and a dip extent of up to 300m that is also open north along strike and downdip.

Notable results include 11m at 13g/t palladium and 1.3g/t platinum along with 17m at 4.1g/t palladium and 0.5 per cent nickel at G11.

Drilling has also extended existing zones with G3 now stretching out over more than 465m of strike and up to 280m dip extent while G4 has been defined to more than 1,000m strike and up to 430m dip extent. Both zones remain open along north along strike and down-dip.

Meanwhile, the G1 and G2 zones that merge at depth now have a strike length of more than 690m and a dip extent of up to 490m.

Assay results are pending for a further 45 completed drill holes.

Chalice managing director Alex Dorsch says that initial activities in the Julimar State Forest have begun that will determine the potential for Julimar to be a multi-deposit, world-class mineral province if previously identified airborne electromagnetic anomalies develop into additional discoveries beyond Gonneville.

Early stage exploration

Meanwhile, BlackEarth Minerals’ (ASX:BEM) geochemistry work has identified a number of strong trends across the southern half of the Donnelly River nickel-copper-PGM project near Bridgetown, Western Australia.

The results confirm the presence of a strong mafic-ultramafic signature across at least three prominent magnetic trends.

Further magnetic trends have also been identified across the property.
