Exco Resources boosts resource at Mt Colin to 1.92Mt at 2.59% copper

13th Sep 2011, 5:39 am

Exco Resources (ASX: EXS) is continuing to progress the Mt Colin copper-gold deposit, increasing the resource by 29% to 1.92 million tonnes at 2.59% copper.  

Previously, the resource inventory was 1.49 million tonnes at 2.47% copper.

Mt Colin is strategically located 50 kilometres from Cloncurry and in the highly prospective Mt Isa region of Queensland.

A Scoping Study completed on the previous resource indicated robust economic potential - current results are likely to further boost the returns.  

The re-estimate has significantly increased the resource size and improved confidence levels of the resource, with the high grade zone still open at depth (350m below the surface).

The resource was confirmed by an additional infill drilling program which comprised 24 diamond holes and 13 reverse circulation holes, with mineralisation still open at depth.

Importantly for the confidence of the resource, the Indicated category jumped 68% to 1.04 million tonnes at 3.04% copper.

Exco said that the resource classification was developed from confidence levels of key criteria including drill spacing, geological concepts, sampling and data density and grade estimation confidence.

Estimates of dry in-situ bulk density were derived from 822 core samples distributed throughout the deposit.

The bulk density values were interpolated using the Inverse Distance squared estimation method with an isotropic search, after which unfilled blocks were then assigned a value based on the correlation between copper and specific gravity.

Meanwhile, Exco has three rigs active at the project, ensuring news flow towards the end of 2011.

Exco has a 100% interest in Mt Colin, which forms part of the Cloncurry Project which has a total resource of 7.65 million tonnes at 1.69% copper and 0.52g/t gold.
