CROWN PGE NICKEL COPPER PROJECT, WA
GOLD PROJECT AT CROWN CLOSE TO MAJOR JULIMAR DISCOVERY
93km2 tenement package located 8km from Julimar major nickel discovery hosts outstanding exploration prospects in mineralised geological setting
The tenement area located only 60-70km northeast of Perth, has been demonstrated by Chalice Gold Mines (ASX: CHN) to be an entirely new PGE-Nickel- Copper province with the potential for multiple Julimar analogues and extensions.
The Crown PGE-Nickel-Copper Project covers a series of prominent magnetic structures similar to the Chalice Gold Mine’s Julimar Complex, and which have not been drill tested.
Company geological team, have conducted an initial site visit to investigate land ccess in the area, paying a particular focus on the eastern most magnetic high.
Favourable metamorphic rocks were observed in outcrop along Blue Plains Road and could be seen to continue into the adjacent property to the south coincident with the respective magnetic high.
The Company aims to identify geochemical soil anomalies that provide evidence of ultramafic sequences within and around the greenstones observed at roadside.
These results will then guide the design of drilling to target potential host lithology nd possible polymetallic massive sulphides, similar to the layered ultramafic intrusive discovered at Julimar to the east.

Geological Setting Discussion
The Crown Project is situated less than 8km from the Julimar Discovery and adjoins Chalice tenure that is the site of Chalice’s recent high grade, broad intervals of PGE-Nickel-Copper mineralisation.
The exploration licence E70/5406 is currently under application and is about to enter the Native title advertisement and negotiation period as part of that process. The Company has started discussions with local landowners and is developing an initial exploration plan that it will undertake once the project has been granted.
Crown lies within the western edge of the Yilgarn Craton. The basement geology is poorly explored and previously misunderstood, with the GSWA failing to identify the intrusive complex, instead having interpreted the Julimar site as granitic.
Recent exploration by Chalice Gold Mines successfully tested the potential of a mafic-ultramafic layered intrusive complex based on high resolution magnetics, and considered it prospective for platinum group elements, nickel and copper despite not ever having been explored for these metals.
Chalice’s broad PGE and nickel-copper intervals, which remain open in all directions, point to a regional scale discovery that may extend far beyond its initial lateral delineation, whilst geological analogues such as the Jinchuan Nickel Mine in China demonstrate what may be found beneath disseminated
Considering the presence of analogous magnetic structures similar to Julimar, the open nature of the Julimar Discovery, the close proximity to new high grade assays, and the absence of previous drilling, Crown has potential to host a significant polymetallic orebody.
Oakdale will now continue access discussions with landowners with the aim to conduct airborne and non-ground disturbing reconnaissance exploration. These exploration initiatives will be designed to pinpoint the most prospective drill targets to be investigated upon grant of the licence and receipt of necessary approvals.
Oakdale views acquiring APM and Crown as transformative for the company and will be fully funded following the recent successful $1.4 million capital raise via Entitlement Offer (ASX Announcement dated 5 June 2020) to conduct aggressive exploration of this exciting new asset.
