Aeris Resources Ltd (ASX:AIS) has received high-grade copper results from diamond drilling at Murrawombie underground mine as part of a brownfields exploration program at the Tritton Copper Operations in Central West NSW.
The drilling has extended mineralisation beyond the current indicated mineral resource envelope by 50 metres down plunge with new Hanging Wall mineralisation also defined over a 170-metre strike length.
Copper sulphide mineralisation was intersected in most drill holes with best results being 15.25 metres at 3.07% copper from 110.75 metres and 34.7 metres at 2.06% from 114.9 metres in the down-plunge section and 30.5 metres at 2.57% from 220.5 metres in the Hanging Wall.
Aeris executive chairman Andre Labuschagne said: “These latest drilling results at Murrawombie are significant as they show that mineralisation continues beyond the current indicated mineral resource envelope, both down plunge and into the Hanging Wall.”
The company believes that the increasing number of drill holes intersecting mineralisation over a long strike length is an excellent indication of the prospectivity surrounding the known mineralised system at Murrawombie.
Other highlights from down-plunge are 4.60 metres at 2.63% from 190 metres and 17.3 metres at 2.05% from 190.4 metres.
Apart from the 30.5-metre intersection in the Hanging Wall, other results include 13.7 metres at 2.18% from 119.2 metres, 9.75 metres at 2.14% from 280 metres, 4.95 metres at 4.72% from 221.5 metres and 4.70 metres at 2.08%
With additional exploration, Aeris is confident there is potential to increase the mineral resource base at Murrawombie, both along strike and down plunge.
In FY2019, Aeris’ Tritton Copper Operations produced 26,852 tonnes of copper and in FY2020 is targeting production of between 23,500 tonnes and 24,500 tonnes of copper.
