Altona Mining has identified a new copper deposit at its Turkey Creek Roseby Project located near Mount Isa in Queensland, Australia.
The Turkey Creek target, where drilling was undertaken to analyse malachite over a strike length of 800m, is located 2km east of the 100 million tonne Little Eva deposit.
The deposit was initially tested using two scout RC holes by Xstrata Copper in 2011, but recent drilling combined both rotary air blast (RAB) and reverse circulation (RC) drilling to define the mineralisation and the economic viability of the deposit.
Altona completed 1,272m of drilling in seven RC drill holes and 3,571m of RAB over an area of 4.5km² to test the target and the planned infrastructure area for the proposed Little Eva processing plant.
Altona managing director Dr Alistair Cowden said, "The deposit clearly has potential to provide additional feed to the proposed Little Eva Plant. There are a great number of similar targets to Turkey Creek within our 1,500 square kilometre tenure. Targets include combined copper anomalous drill and soil results, old workings and geophysical targets."
"Targets adjacent to the main Roseby deposits may have had recent work but those 10-30 kilometres distant may have had little or no exploration in the past 30 years. The Roseby tenements also show clear potential for both Dugald River zinc-lead-silver and Mary Kathleen uranium targets," Dr Cowden added.
Drilling at Turkey Creek intersected low to medium grade copper mineralisation over a 400m strike length and 50m width, including 5m of higher grade zones with 1.18% copper.
The company expects to complete an initial inferred resource estimate before 2013.
