Commonwealth Hill IOCGU Project (South Australia)

Overview & Exploration

 

Apollo has a 100% interest in Commonwealth Hill located in the Gawler Craton in South Australia. The project comprises five tenements covering an area of 1,793km squared.  

In December 2009 Western Plains Resources Limited announced its withdrawal from the farm-in joint venture agreement with Apollo in respect of iron ore on Apollo’s Commonwealth Hill tenements. As a result, Apollo retains 100% of the right to iron ore and all other mineralisation at Commonwealth Hill.

The local area is highly prospective for iron ore, copper, gold and uranium. Olympic Dam (largest uranium mine in the world), Prominent Hill and Challenger Gold mines are all close to the project area as are a large number of iron ore exploration projects including projects held by Western Plains, Ironclad Mining, Stellar Resources and IMX Resources.

A programme of ground reconnaissance geophysical surveys was completed over the Wirrida and Ibis magnetic anomalies in April 2009. At Wirrida a total of eight north-south and two east-west traverses for a total of 19.1 km were surveyed with ground magnetics and gravity. The data shows a broad gravity anomaly which is semi-coincident with the magnetics. The depth of the anomaly appears to be about 50m and possibly less in places. The magnetite-rich horizons extend over a combined strike length of about 7-8 km on the western side of the Wirrida anomaly.

Following the completion in 2009 of ground magnetic surveys and subsequent modelling, the Company is now in a position, with some minor additional modelling, to accurately target drill holes in the most prospective anomalies.

There are eight anomalies which can be classified into two types:

• Linear anomalies that may represent banded iron formation and/or magnetite in schist or gneiss; and

• Circular, more discrete anomalies that may represent small basic intrusions or pipelike bodies containing magnetite that are less likely to have significant iron ore potential but may have base metal-gold potential.
