NEW SOUTH WALES PROJECTS


MUNDI COPPER-GOLD PROJECT

The Mundi Project is a large-area, conceptual greenfield exploration project spanning over 1300km2 of the Curnamona Province, located approximately 115km NNW of Broken Hill. The Curnamona Province is a known iron oxide copper-gold (IOCG) mineral province with the potential for other mineral systems, such as Broken Hill Type Pb-Zn-Ag. The Project area has no known basement outcrop and very limited previous exploration.

The Mundi Project area targets the shallowest portion of the Curnamona Conductor (CC), a crustal-scale conductivity anomaly that has strong similarities to Magnetotelluric (MT) conductivity anomalies that have been interpreted to be associated with IOCG mineralisation in South Australia’s Gawler Craton

In November 2024 SER announced results from a Moving Loop Electromagnetic (MLEM) and Airborne Magnetic and Radiometric Survey (AMR) undertaken at Mundi to ground truth the previous MT modelling. Modelling has confirmed a significant conductive body at drillable depth that is associated with a remanent magnetic body. This is believed to be a new and unexplained relationship within the Curnamona Province and whilst there are numerous geological settings which could result in this relationship that include non-mineralised settings, intrusion related mineralised systems may also produce a similar response and therefore further exploration is warranted. Work is now underway to identify analogues in the Curnamona Province that share similar geophysical signatures to guide further exploration. Furthermore, given the project area contains multiple look-alike reversely magnetised bodies, future work will include additional ground EM and detailed drone magnetics over these prospects to model their depth and conductivity prior to target ranking and a future drill program.

WEST KOONENBERRY COPPER-NICKEL PROJECT

The West Koonenberry Project covers 483.5km2 of unexplored ground that SER interprets as the western extension of the Koonenberry Cu-Ni belt. The project is located approximately 100km NE of Broken Hill and adjacent to our Mundi Project.

SER interprets the linear magnetic rocks within the project area to be analogous to the Mount Arrowsmith mafic sills of the Koonenberry belt to the east, which is a highly prospective belt for Cu-Ni rich massive sulphides. The Koonenberry belt has previously been explored by INCO/Vale and IGO and is currently being explored by S2 Resources [1] (ASX:S2R). SER is targeting the equivalent mafic host rocks on the eastern edge of the Curnamona block, rifted from the Koonenberry belt during the formation of the Bancannia Trough. The Koonenberry belt is interpreted to be analogous to the Pechenga Copper-Nickel camp in Russia. 

This year SER has completed and airborne magnetic survey across the entire tenement, secured land access and completed a reconnaissance field mapping trip at West Koonenberry. SER has also engaged CSIRO as part of a Kick-start Program that will access CSIRO research expertise to investigate the prospectivity of West Koonenberry to host a magmatic Ni-Cu-Co-PGE deposit. The objectives of the project are to confirm the presence of prospective geological units, particularly the hypothesised second belt of the Mt. Arrowsmith Volcanics, and map nickel-copper sulfide targets undercover [2].
