ASX ANNOUNCEMENT
ASX : CXO
28[th] August 2012
4% copper found in outcrop at new Choppy Prospect Fitton Project, northern S.A.
HIGHLIGHTS
-
Copper mineralisation grading up to 4% Cu has been found in outcrop of the new magnetic targets identified at the Fitton project in South Australia
-
Scale of copper, uranium and gold potential is building at Fitton
-
First Fitton project drilling program planned for late in 2012
Core Exploration Ltd (ASX:CXO) is pleased to announce new high-grade copper assays of surface outcrop at the new Choppy Prospect within the Company’s 100% owned Fitton Project (EL 4569) in northern South Australia.
The most exciting assays collected out of the 8 samples taken at the new Choppy Prospect include:
| | Sample MP | 00552: | 4.7% Cu | 0.75 g/t Au | 20 g/t Ag |
|---|---|---|---|---|---|
| | Sample MP | 00552: | 0.25% Cu | 1.0 g/t Au | 1.6 g/t Ag |
In addition to previously noted elevated uranium at the Scott Lee Prospect (also at Fitton), high gold and silver levels are associated with copper mineralisation at Choppy (Table 1 and Figure 2).
The Choppy Prospect is located 400m southwest of the promising Scott Lee Prospect. Copper mineralisation at Choppy consists of malachite bearing quartz + hematite rocks along zones of sheared granite that are magnetic at local scale (Figure 2).
Importantly, there are an increasing number of magnetic anomalies being defined by Core’s recent magnetic surveys. Three new magnetic targets of similar dimensions to Scott Lee and Choppy have been identified to the east and south (Figure 1). Further mapping of these areas is currently underway to identify additional surface expressions of mineralisation.

The most significant magnetic anomaly identified to date is a much larger magnetic anomaly 2km south-west of the Scott Lee Prospect. While it is yet to be established if this new 1,400m long and 250m wide anomaly is associated with the same mineralising system, it nevertheless presents an exciting exploration target for further work (Figure 1).
As at the Scott Lee Prospect, mineralisation at the Choppy Prospect is associated with a shear zone and is magnetic at a local scale. Previous surface sampling by Core at Scott Lee has shown significant levels of copper and uranium. A number of samples contained highly anomalous uranium above 100ppm for a strike length of over 800m and graded above 1% copper over a strike length of 150m (Figures 2 & 3).

Next Steps
A follow-up mapping and sampling program has commenced at Fitton. Assay results are expected in late September.
Following the positive results of finding new outcropping copper mineralisation associated with ground magnetic anomalies, infill magnetics at the Scott Lee Prospect on 25m line spacing has been completed.
The magnetic anomaly at Choppy is of a similar strike length to Scott Lee, doubling the currently defined target size for drilling planned for later this year. Core’s first drill program on Fitton is planned to commence later in 2012, subject to necessary approvals.
