Redbank Copper Ltd (ASX:RCP) has identified several compelling anomalies along trend of known copper mineralisation during the initial gradient array induced polarisation (GAIP) survey within the Redbank Copper Project in McArthur Basin, Northern Territory.
Exploration started on June 4, 2021, with initial work including GAIP surveys and large-scale soil sampling.
Both are proven methods for discovering disseminated copper mineralisation in the McArthur Basin.
The first GAIP area surveyed was positioned over the Bluff deposit with immediate success.
Redbank has also identified two discrete and unexplained high-order chargeability anomalies and these targets will be tested with a drilling program planned to start in Q3 2021.
“Several exciting and unexplained anomalies identified”
Redbank executive director Michael Hannington said: “We are delighted to have encountered immediate success from our 2021 exploration program at Redbank, with several exciting and unexplained anomalies identified within close proximity to the existing Bluff copper deposit.
“Importantly, these initial results demonstrate that we have a proven exploration technique to search for copper mineralisation within our district-scale project area in the McArthur Basin and we are continuing to build a suite of high-quality targets to be tested with our maiden drill program.
“The Redbank Project continues to reveal its underlying potential and our technical team is beginning to get a glimpse into the true scale and prospectivity of our project area.
“Our targeted exploration program continues apace and we look forward to providing further updates on progress.”
Redbank Project
The Redbank Project is in the east McArthur Basin about 30 kilometres west of the Northern Territory/Queensland border.
In July 2020, Redbank expanded the size of the project area and secured a district-scale tenement holding by pegging open ground following work by Geoscience Australia that highlighted the prospectivity of the area for large base metal deposits between the world-class Tier 1 zinc deposits at the McArthur and Century Mines.
The company is searching for large copper deposits to add to the existing copper inventory.
Further target generation work
Redbank’s soil sampling program continues to expand eastwards from the anomalous area identified at Bluff deposit to add to the existing copper inventory.
Before starting ground geophysical IP surveys, Redbank contracted an airborne electromagnetic (VTEM) survey over an area partially covered by regional-scale soil sampling in 2020.
The VTEM survey is scheduled to start in early July and will provide a technique to image the stratigraphic layers which host the breccia pipe copper deposits.
Further target generation work using airborne electromagnetic and MT (magnetotellurics) surveys will start in early July with additional results to be reported in due course.
