Impact Minerals restarts nickel and gold exploration at Mulga Tank
THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has completed a three month exploration program at the company’s 100 per cent-owned Mulga Tank project, located east of Kalgoorlie in Western Australia.
The company has re-booted its exploration for nickel and gold on the project with the completion of three major surveys: an airborne magnetic and radiometric survey covering most of the 425 square kilometre project area; an innovative combined ground and airborne electrical survey; and the collection of 2,500 soil geochemistry samples.
“The data generated from this work will be mostly used to help define drill targets identified at the Mulga Tank Dunite and Panhandle prospects in the western part of the project area,” Impact Minerals said in its ASX announcement.
The airborne magnetic and radiometric survey was completed at a line spacing of 50 metres, four times greater detail than previously available data, which the company said had greatly improved its geological understanding of the entire project area and in particular over the Mulga Tank Dunite.
“This is important because the entire project lies under deep sand cover at least 50 metres thick in most places,” Impact explained.
“A detailed interpretation of this data is in progress.”
The ground and airborne electrical survey included the Panhandle and Mulga Tank Dunite prospects, covering about 15 km of strike of nickel prospective rocks for a total area of about 70 square kilometres.
“The purpose of the survey was to help identify units of metasedimentary rocks under the thick sand cover,” Impact said.
“These units generate a significant number of false anomalies for nickel sulphides in conventional electromagnetic surveys.
“Final data is expected within two weeks.”
As part of the soil geochemistry survey around 1,000 soil samples were taken over the eastern half of the Mulga Tank Dunite at a spacing of 200m by 50m and 1,500 samples have been taken over the Panhandle prospect at a spacing of 100m by 50m.
Selected samples from areas of interest identified in the new geophysical data will be sent for assay in December.
