Antares spots new copper target areas at Conglomerate Creek

Several new target areas have been outlined during two geophysical surveys
The work program included a magnetic and gravity survey
Antares is planning to conduct a drilling program to test these priority targets

Special Report: Antares Metals has made an exciting development in the early stages of exploration at its Conglomerate Creek prospect near Mt Isa in Queensland, with the discovery of multiple target areas.

An extensive high-definition magnetic and gravity survey defined the targets, which include structural corridors with coincident magnetic and gravity anomalism as well as anomalism associated with lithological changes.

With limited modern exploration carried out at Conglomerate Creek – part of the wider Mt Isa North project in Queensland – Antares Metals (ASX:AM5) believes the results are highly encouraging.

Major structures on the 2003km2 landholding were only superficially explored between the 1950s and 2010s with minimal drilling undertaken, apart from a stint in the 1970s which returned impressive intersections up to 7.77% copper at the historical Surprise mine.

3D inversions underway

AM5 CEO Johan Lambrechts said the company is very pleased with the results.

“Geophysical surveys are an integral part of modern exploration with processing and interpretation having identified some exciting targets,” he said.

“Additional 3D inversions are now being carried out to better understand the depth and scale of each target.”

The ground gravity survey comprised an offset grid of 200m x 200m stations, resulting in a high-definition gravity image of the area.

To complement the gravity data, a high-definition drone magnetic survey consisting of 50 metre-spaced lines was also flown.

Geophysical consultants, Terra Resources, processed and interpreted the datasets and are following up with an additional inversion of the data to generate a three-dimensional image of the magnetic and gravity data.

Survey results

Results of the magnetic data show meta-basalts almost entirely cover the area examined by the survey, which exhibits a distinct magnetic low region skirted by structures.

The anomalous areas identified as potential targets align with structures or are unexplained, isolated ‘islands’ within the general magnetic low area.

Meanwhile, the interpreted gravity results also identified several areas with anomalous gravity signatures coupled with geological and associated magnetic anomalism.

The gravity map indicates a distinct gravity-low region skirted by structures that match the area highlighted by the magnetic interpretation.

Work is now underway to invert the Conglomerate Creek geophysical dataset to generate a 3D magnetic and gravity image and assist in refining potential drill targets.

AM5 is planning to conduct a drilling program to test these priority targets.
