Aeris Resources Ltd Finds High Grade Copper Beneath Murrawombie Resource in Tritton Operations
Aeris Resources Ltd (ASX:AIS) has further enhanced the copper potential of the Murrawombie deposit in the Tritton operations in New South Wales with high-grade copper intersected beneath the resource.
Underground exploration drill hole MWNM001 targeted extensions of the mineralized system downstream of the current mineral resource footprint and returned good results, intersecting several high-grade lenses.
- 8.0 meters at 2.05% copper, 0.47 g/t gold and 7.6 g/t silver from 845 meters;
- 21.3 meters at 1.78% copper, 0.48 g/t gold and 7.4 g/t silver from 858.5 meters including 11.1 meters at 2.72% copper , 0.78 g/t gold and 11.7 g/t silver from 868.7 meters; and
- 6.7 meters at 1.02% copper, 0.21 g/t gold and 1.9 g/t silver from 806.3 meters.
The Murrawombie deposit has now been traced to 1,400 meters depth.
Life extension potential
Executive Chairman André Labuschagne said, “These latest drill results continue to demonstrate the possibility of finding more copper on the Tritton claim lot.
“The mineralization intersected downstream of the Murrawombie deposit has the potential to significantly extend the life of the Murrawombie subsurface.
“We will prioritize downhole EM surveys over the hole and schedule follow-up drilling.”
Murrawombie is the second largest deposit discovered in the Tritton claim complex with in situ tonnage in the range of 15 to 20 million tonnes.
Primary copper mineralization in the form of chalcopyrite is associated with pyrite forming a series of stacked sulphide lenses traced from surface to 1,100 meters at depth.
An underground exploration drill hole was recently completed targeting extensions of the mineralized system at depth below the current mineral resource footprint.
The high grade copper intersections are 250 meters below the resource footprint.
No sign of weakening
Aeris says the results from hole MWNM001 are exciting for several reasons:
- First, the intersection of several high-grade lenses suggests that the mineralized system does not show signs of weakening; and
- Second, there is significant potential to expand the current mineral resource inventory with further exploration drilling.
A common feature of the deposits within the Tritton complex of buildings is a long down plunge dimension.
The Tritton deposit remains the largest mineralized system discovered to date in the complex of buildings and has been traced over more than 2,000 meters down plunge and remains open.
What happens after
A downhole electromagnetic survey will be completed on drill hole MWNM001 to detect massive sulphide lenses up to 200 meters from the drill trace.
Results from the survey will be used to facilitate follow-up drilling planned to test extensions of mineralization below the current resource footprint.
