Located in the central western part of the Gawler Craton and targeting:

(a) gold and copper mineralisation within the Central Gawler Gold Province,
similar to the Tunkillia and Nuckulla Hill prospects;

(b) potential IOCG deposits; and

(c) palaeo-channel roll front uranium deposits.

The prospectivity of the Yarlbrinda Shear zone has been demonstrated by the discovery of gold at the Nuckulla Hill and Tunkillia to the north of Toondulya. Toondulya has a similar geological setting to Tunkillia.

Defined potential geophysical targets and major, high order gold and base metal geochemical anomalies. Coincidence of small circular magnetic low with small circular gravity high and calcrete gold anomaly.

Located within a zone of structural dilation where the Yarlbrinda Shear Zone intersects the northern edge of the Arcoona Horst block, Toondulya is well located in terms of exploration potential.Magnetized triple point structural junction of Fe-rich Hiltaba Granites.
