Thomson Resources says its auger drilling program in the Chillagoe region has turned up copper oxide azurite – a surface indicator of the presence of weathered copper sulphide ores.
The auger drilling program – which has seen 240 holes drilled to date – is targeting 10 prospect areas in the Chillagoe project owned by Bacchus Resources.
It follows an agreement for Thomson to acquire a 90 per cent interest in the tenements, 150km west of Cairns.
A number of the samples taken during the auger drilling program have been sent for analysis and assaying, with first results expected in late November.
Meanwhile Thomson says rocks collected during the program at the Laverock target area have shown a strong presence of copper oxide azurite.
It is usually found in association with the chemically similar malachite, producing a striking colour combination of deep blue and bright green that is strongly indicative of the presence of copper ores.
“This early indicator starts to reinforce the copper potentiality of the Chillagoe project along with the already known gold potential,” the company said in a statement to the ASX.
Rock chip sampling previously undertaken by Bacchus on the Laverock
target area had confirmed anomalous gold and copper of up to 5 g/t gold and 1.3 per cent copper.
The Chillagoe project comprises six EPMs (Exploration Permit for Minerals), five of which are granted, in an area near the Mungana, Red Dome and King Vol mining operations.
