Estrella Resources Limited (ASX: ESR) has re-commenced diamond drilling activities at the Carr Boyd Nickel Project (CBNP), north-east of Kalgoorlie in Western Australia.
The programme will test at depth and along strike of the T5 nickel-copper discovery.
CEO Chris Daws said the company plans to firstly commence diamond core hole CBDD042 located approximately 150m south of discovery hole CBDD030 and 130m underneath CBDD041, its final drill hole of 2020, which intersected the interpreted “mineralised conduit” confirming the T5 discovery over potential strike length of at least 450m.
The deeper diamond drilling of T5 is essential from both a geophysical and geological perspective having a large relative mid-high conductivity EM response plunging away from initial discovery RC and diamond holes.
T5 is less than 1.5km from the historic Carr Boyd mine which could itself represent remobilised high grade massive sulphide from a source in the immediate area. The grade of the massive sulphide at Carr Boyd is known to be around 6% nickel and 3% copper which provides a compelling target for exploration.
Last year’s diamond drilling campaign at Carr Boyd was an outstanding success,” Mr Daws said.
“We have discovered what is now clearly looking very much like a ‘feeder’ to the CBLC and the hunt is now well and truly on in 2021 to uncover the massive nickel and copper sulphide source I have always believed existed at Carr Boyd. The strongly mineralised conduit has been intersected in multiple diamond drill holes at T5 and providing our team with a clear geological model.
“With every hole that we drill we are one step closer to delivering a successful outcome for our shareholders and I am certainly looking forward to each and every meter of drill core that is placed on the core-farm racks.”
The CBLC is a 75 sq. km layered mafic igneous complex, which hosts several occurrences of nickel and copper sulphides. The most significant occurrence discovered to date is at the Carr Boyd Rocks mine, where mineralisation is hosted by bronzitite breccias (pyroxenites) emplaced within the gabbroic sequence of the Complex.
The CBLC is in a Tier 1 jurisdiction approximately 80km north north-east of Kalgoorlie Western Australia. An all-weather haul road accessible by Estrella under a granted miscellaneous license connects the Project to the Goldfields Highway via Scotia.
A “Voisey Bay” style model has not been adequately explored within the CBLC. This represents a compelling exploration target opportunity which the Company will continue to aggressively pursue.
