Breakaway Resources (ASX: BRW) has discovered a potential new zone of copper-gold mineralisation at the Sandy Creek prospect along with potential for down-dip extensions of the existing mineralisation.
The parallel zone of copper-gold mineralisation is located 100 metres west of the main mineralised zone at Sandy Creek.
Three broadly spaced diamond drill holes were completed in early December to test the prospect’s wider potential, with one hole intersecting 14.38 metres at 0.72% copper and 0.37 grams per tonne (g/t) gold from 85.42 metres, including 3.53 metres at 1.64% copper and 0.21g/t gold from 96.27 metres.
Mineralisation intersected in the new zone bears similarities to the existing mineralisation at Sandy Creek.
Significantly, each of the three diamond holes also intersected the target shear zone about 100 metres down dip of the main mineralised zone at Sandy Creek.
The best intercept was 1.1 metres at 0.35% copper and 2.2g/t gold from 215 metres.
The presence of the host structure and associated mafic/garnet alteration at the target position suggests potential for further mineralisation at depth.
Meanwhile, down-hole time domain electromagnetic (DHTEM) surveying carried out on the three diamond drill holes has identified a strong off hole anomaly within the main zone of mineralisation.
Breakaway managing director David Hutton said the new copper-gold mineralised zone and potential depth extensions were encouraging for the company.
“When considered in conjunction with the DHTEM anomaly and the broad spacing of existing drilling, the results continue to reinforce the significant size potential of the prospect.
“Sandy Creek continues to grow and, as a result, we are yet to find the limits to the copper-gold mineralisation. We are currently determining the next steps to better establish the prospect’s true size. This may include further drilling of the DHTEM anomaly and the new western zone, as well as further geophysical surveying throughout the prospect area” Mr Hutton said.
The DHTEM anomaly has been modelled to have a southerly plunge of 400 metres strike to a depth of 200 metres, and extends down plunge from drill intercepts of:
- 3 metres at 3%copper and 0.92g/t gold;
- 2 metres at 2.46% copper and 0.63g/t gold; and
- 13 metres at 1.1% copper and 0.18g/t gold.
These latest results will provide targets for follow up drilling in 2012.
