Norwest Minerals Limited (ASX: NWM) has discovered very high-grade copper–gold-quartz veins extending across multiple target areas at the company’s 100% owned Bali Copper Project in Western Australia.
Recent earthworks to clear drill sites along the Bali Shear has opened access to the Deep South area where no records of past exploration exist, but recent Norwest exploration work has now identified high grade copper-gold quartz veins with wide-spaced rock chips reporting consistently high-grade assays of up to 46.2% copper and 6.74g/t gold.
“The discovery of the new copper-gold bearing quartz veins is a very exciting outcome following Norwest’s recent commencement of work at the previously unexplored Deep South area,” CEO, Charles Schaus, said.
“Drilling is already underway to test four historical copper prospects along the Bali Shear, whilst drill planning to test the down dip extent of these new high grade copper-gold quartz veins is being undertaken alongside ongoing exploration fieldwork programmes.”
Bali shear – recent mapping and sampling
Norwest recently undertook earthworks to prepare drill pads for the 4,000m RC drill programme currently testing for copper mineralisation at the Bali Lo, Bali High, Bali East, and Bali South copper prospects.
The ground clearing created access southeast along the Bali Shear and into the previously unexplored Deep South area. Near the eastern tenement boundary where the new access track crosses the Bali Shear, rock chips returned copper assays up to 27.7% copper. The overall exploration target area along the Bali Shear now covers 5.5 kms from the Bali Lo prospect to the eastern tenement boundary.
Deep South – recent mapping and sampling
In the Deep South area, exploration mapping identified five new copper-gold bearing quartz veins extending a total of 2.25 kilometres.
Lab assays from the wide-spaced rock chip sampling along the individual veins reported consistently high-grade copper with associated gold.
The copper-gold quartz veins are associated with near vertical dipping, laterally extensive, narrow shears zones striking NW-SE parallel to the main Bali Shear. The high-grade core of the shear zones comprises a chalcocite dense quartz vein breccia within intensely silicified and kaolinized host siltstones of the Ashburton Formation.
Norwest has mobilised a geologist to site to continue the surface exploration work at the Deep South area. The information will be used to develop a drilling program to test the down dip extent of the high-grade copper-gold quartz veins discovered at this exciting new exploration target.
