THE DRILL SERGEANT: Altona Mining announced a batch of encouraging drilling results from the company’s 100 per cent-owned Roseby copper project located in the Mt Isa-Cloncurry mining district in Queensland.
Altona has completed a 15 hole and 2,850 metre RC drilling program at the Ivy Ann copper-gold deposit, situated 30 kilometres south-east of the main Roseby project area.
The company identified the most significant result from the drilling program to be a high-grade portion of mineralisation of 2m at 19 per cent copper, which was intersected at shallow levels at the north of the deposit where it remains open to the north.
Altona said it had designed the drilling to increase resources and improve understanding of the continuity and style of mineralisation at Ivy Ann.
The drilling will also provide the company with material for initial metallurgical test work.
Highlights received from 12 drillholes so far at a 0.30 per cent copper cut-off grade include:
– 13 metres at 3.42 per cent copper and 0.45 grams per tonne gold from 21m, including 2 metres at 19.4 per cent copper and 2.69 grams per tonne gold from 22 metres;
– 25m at 1.21 per cent copper and 0.15 g/t gold from 184m, including 9m at 2.17 per cent copper and 0.29 g/t gold from 185m;
– 23m at 1.18% copper and 0.25 g/t gold from 41m, including 7m at 2.16 per cent copper and 0.48 g/t gold from 42m; and
– 35m at1.10 per cent copper from 88m.
“The significance of the Ivy Ann deposit is that it has the potential to provide supplementary feed to the proposed new mine and mill at Little Eva at a higher grade than the average grade of Little Eva,” Altona Mining said in its ASX announcement.
“Drilling was designed to test possible extensions to the west, north and down-dip and to infill existing drilling.
“The majority of the holes intersected sulphide copper-gold mineralisation.
“Assay results have been received for 12 holes and confirm continuations to north, west and down dip.
“Numerous zones of mineralisation up to 35 metres down hole were intersected often including high grade intervals above one per cent copper.”
