Established Australian copper producer and explorer Aeris Resources (ASX: AIS) has provided an update on recent drilling at its Murrawombie underground mine, part of the Tritton Copper Operations.
· High grade copper intersected beyond current Murrawombie Mineral Resource footprint, including:
· 6.25m @ 4.64% Cu (MWGC418)
· 12.75m @ 3.62% Cu (MWGC443)
· 7.85m @ 3.64% Cu (MWGC408)
· 14.00m @ 2.77% Cu (MWGC441)
· 20.20m @ 2.52% Cu (MWGC440)
· Massive sulphides intersected 60 metres along strike from current Mineral Resource
· Copper mineralisation remains open along strike and down plunge
· Continues recent success from Tritton exploration activities
· Drilling to test for down plunge extensions commenced in mid-August
A recently completed diamond drilling programme, targeting extensions to the dominant mineralised lode (lode 102) outside of the current Mineral Resource envelope, has returned excellent results along strike and down plunge.
These recent drill results extend the massive sulphide mineralisation up to 60 metres along strike (north), beyond the northern extents of the current Mineral Resource envelope. Additionally, copper sulphide mineralisation was intersected beyond the 102 lode further into the Hanging Wall (HW).
The drill intersections in the HW of the 102 lode are an excellent indication of the prospectivity surrounding the known mineralised system at Murrawombie, highlighting the potential to increase the Mineral Resource base, both along strike and down plunge, with additional exploration.
Whilst the drill spacing is sparse it appears there are potentially multiple sulphide lenses in the HW to the 102 lode. Geological work is ongoing to interpret the number of lodes and their spatial continuity. Further drilling is planned in FY20 to assist with the interpretation and geological modelling process.
The drill rig will now complete two wide spaced drill holes planned to intersect the interpreted 102 lode horizon 150 metres along strike and 190 metres down plunge beyond the known extents.
Results from both drill holes will assist in understanding the potential of the larger mineralised footprint and assist with future drill planning and mine design.
The latest drill results will be included in an updated Mineral Resource estimate for Murrawombie, which will be completed before the end of the current quarter.
Aeris Executive Chairman, Andre Labuschagne, said, “The latest drilling results from Murrawombie are very promising and demonstrate the prospectivity for further high-grade extensions along strike to the north and down plunge.
“Since we commenced operations at the Murrawombie underground mine in FY17, it has consistently exceeded expectations on both tonnes and grade.”
