Sovereign Nickel-Copper-PGE Project, WA


The Opportunity


The Sovereign Project is located in the highly prospective Julimar region of Western Australia, ~70km north-east of Perth. The Project is centred on the Sovereign Magnetic Complex and located between the Gonneville Ni-Cu-PGE discovery to the south, owned by Chalice Mining Limited (ASX: CHN), and the Yarawindah Brook Ni-Cu-PGE Project (Caspin Resources Limited, ASX: CPN), to the north (Figure1). 

DevEx’s holdings within the region includes the Sovereign Project alongside three additional Exploration Licence Applications, all considered prospective for magmatic nickel-copper-platinum group elements.

Sovereign Project Background


The Sovereign Project was secured in June 2020 through an Earn-In Agreement with Australian Silica Quartz Group Ltd (ASQ). The Agreement secured access to the highly prospective target - the Sovereign Magnetic Complex, which extends over both the ASQ Tenement and DevEx’s 100%-owned, neighbouring tenement located directly to the east (E70/5365). 

The Sovereign Project overlies a magnetic complex of rocks that is interpreted to be part of the same mafic-ultramafic intrusive rocks hosting the Julimar Complex, where the recent high-grade palladium and nickel mineralisation was discovered by Chalice to the south (Figure 2). Refer to ASX Announcement – 1 June 2020  for full details. 




A maiden drilling program is currently underway to test the western half of the Sovereign Magnetic Complex. Drilling is designed to test several targets within the large, 6km x 7km Sovereign Magnetic Complex, where previous assaying of shallow bauxite and rock chip sampling drilling returned multiple areas of anomalous nickel, copper, chromium and PGE results (see ASX Announcement – 19th August 2020).

Several areas – including the Kingsley, Hudson and Mackenzie anomalies – include multiple anomalous zones with coincident Cu and Pd+Pt plus supporting Ni and Chromium (Cr) results. The areas coincidently overlie several late-time airborne EM conductors (Figures 2 and 3), and are considered priority drill targets (see ASX Announcements - 8th February 2021).
