The project principally covers granitic rocks of the Kurnalpi Terrane with minor mafic rocks on the margins. Systematic soil and auger geochemistry has been completed by other companies in the late 1990s. Depth of recent transported cover rocks is unknown and review of past work is recommended prior to commencing on ground exploration activities.
Mapping in the previous quarter indicated extensive alluvial hematite in the valley of Cowarna Creek. The hematite extends for 3.4km up to the north boundary of the tenement, and is about 700m wide. The thickness of the hematite rich alluvial deposit is unknown, and drilling is required to determine the thickness, percentage recovery of hematite and grade of the recoverable hematite.
A drill pattern of 130 aircore holes was planned during the December Quarter, with east-west lines 200m apart, with holes 100m apart along lines. A program of work to drill these holes was submitted to the DMP, and approval was received. The initial holes were drilled as one aircore hole per line in the middle of the deposit, with 18 holes drilled for 96m.
Drill samples of the hematite rich gravel were taken at 1m intervals, and have been submitted for dry magnetic separation of the hematite granules, and analysis of the hematite product. The holes were logged, with a visual estimate of the percentage of hematite granules recorded. The hole locations and hematite granule intervals and percentage estimate are in Table below, Cowarna Creek Hematite Granule Intercepts.
A pit was dug in the centre of the deposit, and the bulk sample of hematite rich gravel submitted to a metallurgical laboratory for testwork.
Results are pending.

- This area has the potential to host Detrital Iron Ore in a river valley as in the adjacent tenement to the west, as shown in the map.
- Mapping and drilling is underway to discover the amount of detrital iron ore occurring in the valley.
- The project area also has the potential for gold and base metals and this will be investigated by soil geochemistry and follow up drilling of anomalies.
