Upper Eastern Eyre Project

 

Upper Eastern Eyre / Iron Baron Project Area

As shown in Figure 1, tenements reside approximately 55km west/southwest of Port Augusta and 50km west of Whyalla, separated into northern and southern block areas.
The northern area presents a number of prospective features:

  • A regional scale gravity anomaly sits within this area (Figure 2), which has been considered by Renascor for its potential to suggest IOCG-style mineralisation.

  • Renascor has evaluated its own data alongside data accessed via a public crowdsourcing competition instigated by the SA Government in 2020 (“the Gawler Challenge”) to develop next generation mineral systems maps for exploration companies. An Old Wartaka TEMPEST anomaly is in the eastern margin of EL 6191, which also sits adjacent to “Per-OZ” (Gawler Challenge winning participant) theoretical Cu-Au targets.

The abovementioned TEMPEST anomaly has been reviewed and also possibly correlates to the regional gravity anomaly noted above in EL 6698 (see Figure 3). Participants “Incalc Exploration” and “Gawler Challenge Group 5 – University of Adelaide” also conducted desktop target generation experiments in the near vicinity.

Flanked by prominent iron ore and uranium resources, the southern tenement block remains lightly explored. It contains the Myola South prospect, a copper with Zn-Mn-Fe-Co geochem. association, approximately 8km southeast of the Iron Baron iron ore mining complex.

When operating under historical EL 4721, an area extending slightly wider than the current EL 6698 southern block bounds, soil geochemical surveys and FPXRF analysis were completed totalling 200 samples.

Initial exploratory reverse circulation (RC) drilling totalling 258m, of two copper targets – Nilginee and Knights, was completed, both defined by gravity geophysics and coincident soil geochemical anomalies noted above.
