Estrella Resources Limited (ASX: ESR) has drilled a further significant intersection of Ni-Cu (+ PGE) bearing sulphides at the company’s flagship Carr Boyd Project, 80km north of Kalgoorlie.
Diamond core hole CBDD033 was drilled at the T5 discovery zone at Carr Boyd Project. The original discovery hole CBDD030 was drilled from the footwall sediment side in order to provide a deep EM platform hole to test the basal contact position for sulphide accumulations. CB00030 intersected significant magmatic Ni-Cu mineralisation.
Discovery hole CBDD030 intersected the CLBC contact, was completely blind and is open in all directions.
Hole CBDD033 was drilled from the opposite direction, drilling back through the CBLC mafic-ultramafic intrusion towards the contact zone targeting above the discovery intersection.
Hole CBDD033 has intersected more Ni-Cu sulphides along the contact zone and is associated with coarse grained gabbroic rocks intruded up the contact between the serpentinised ultramafics of the CBLC and the footwall basalts.
MD and CEO, Chris Daws, said the sulphide mineralisation occurs over a substantial 25.7mdownhole wide zone (~20m true width) comprising of pulses of Ni-Cu bearing massive, matrix, disseminated and breccia sulphides.
Additional stringers and blebby sulphides occur within the footwall basalts outside of the reported zone, supporting the intrusive remobilised nature of these sulphides being derived from a larger primary sulphide source chamber at depth.
Our team has again delivered another significant drill hole confirming the extensive DHTEM plate surrounding our initial discovery hole hosts substantial nickel sulphide mineralisation,” Mr Daws said.
“We are moving fast to see what further mineralisation exists at T5 with two diamond rigs drilling 24/7 into the defined DHTEM plate, I expect from here we will continue to see more significant results.
“I am extremely pleased with what has thus far been achieved and I look forward in the days, weeks ahead as the drill bits keep turning on what has been a remarkable program to date.
“As the company gears up for expanded drilling efforts focusing on the T5 Target area we are also rapidly expanding our infrastructure at the project location.
“We have recently improved the communications at site, with the erection of a communications tower to provide high speed internet and reliable phone service. The old haul road is now being graded and improved to facilitate the transport of an exploration camp and office block buildings to site,
“The core yard facility upgrades, and site office installations are in progress, with bulk water and diesel fuel storage also being established.
“ An old airstrip located 4km east of the Carr Boyd Mine has also been re- established by the local station owner for RFDS and charter flight site visits of company personnel.”
