Oar Resources forges ahead with exploration at Crown, the closest exploration project to Chalice Mining’s world-class Gonneville Nickel-Copper-PGE Project.

Oar Resources is continuing exploration activities at the Crown Nickel-Copper-PGE Project in Western Australia’s Julimar district, with systematic soil sampling and field mapping ongoing in the hopes to identify priority drill targets for its maiden drilling program.

Around 310 soil samples have been collected from a priority-1 target to date and submitted for P-XRF multi-element analysis.

Results from this work will assist in the identification of underlying geology where there is no outcropping basement and will provide geochemical targets for the first phase of drilling.

Oar (ASX:OAR) expects the initial soil sampling results to be returned this week.

Expanded footprint

The metals explorer has also expanded its land access footprint at the Crown project, with the signing of an additional land access agreement.

OAR said this has opened up new high-priority target areas, set to be an immediate focus for the ongoing soil sampling and mapping programs.

Petrological analysis from the rock chip sampling program has confirmed the presence of ultramafic amphibolite rocks containing copper sulphides – confirming the presence of the targeted host rocks at Crown.

The company has systematically compiled mapping and outcrop sampling data to build on the regional and project-scale geological setting.

This work has led to the definition of two broad geological domains, the Western and Eastern Domains; with the less prospective Western Domain dominated by granitic lithologies, and the Eastern characterised by a mixture of the targeted mafic, ultramafic, and granitic lithologies.

Results for 14 samples pending

A total of 74 rock-chip samples have been submitted for laboratory multi-element analysis to date, with field observations of collected samples continuing to be positive, building on the regional geological interpretation.

Assays have been returned for 60 of the initial samples collected, with no significant results reported.

Results for the remaining 14 samples are pending and will be released when available.

Rock chip results to date have come from sampling over a very limited part of the project area, and predominantly on the Western Domain which has been found to be dominated by granitic lithologies. However, the company’s more recent ground-based activities has established the presence of ultramafic rocks on the Eastern Domain of the project area.

Based on this work, OAR will now move to focus its ongoing exploration efforts on the more prospective Eastern Domain, where the company previously announced it had mapped and sampled a package of north-south trending ultramafic rocks.

The identification of these ultramafic rock packages within the Crown Project tenement is considered by the company to be significant, as ultramafic rocks are the host rocks of Chalice Mining’s (ASX: CHN) nearby world-class Gonneville Ni-Cu-PGE deposit.


The Crown Project contains numerous magnetic features interpreted to represent mafic volcanic rocks considered to be highly prospective for similar nickel-copper-PGE and gold mineralisation to that found at the Gonneville Deposit.

Oar is undertaking a technically driven, staged, and systematic exploration approach at Crown to better understand the geological setting of the previously unexplored area –

Stage 1: Detailed geological mapping and outcrop mapping, aimed at identifying basement geology which has historically been poorly understood and mis-mapped;

Stage 2: Systematic soil/surface geochemical sampling, aimed at defining drilling targets. (This stage may include ground or airborne geophysical surveys); and

Stage 3: Drill testing of identified anomalies.
