Redstone Resources Limited (ASX: RDS) has commenced the second phase of reverse circulation (RC) drilling on the company’s 100% owned West Musgrave Project in Western Australia.
The second phase follows‐on from the first phase completed in late 2021 and will consist of approximately 5,000m of drilling (including deep drilling at 300m+ depths). The Programme includes drilling the EM5 Target and two other EM5 ‘look‐a‐ like’ magnetic anomalies, as well as at the Tollu copper veins and surrounding prospective Target Areas.
The drilling will target copper mineralisation but also test for rock types that have the potential to host nickel‐cobalt‐copper mineralisation.
Further evaluation of the Tollu Copper Project, surrounding Target Areas and the broader West Musgrave Project, has the potential to add to the company’s Tollu copper resource of 3.8 million tonnes at 1% Cu, containing 38,000 tonnes of copper.
TARGET EM5
Target EM5, is an EM target coincident with a large circular magnetic anomaly located 7.2km northeast of the Tollu copper vein deposit.
Previous drilling at the EM5 Target intersected a gabbroic rock bearing a thick sequence of anomalous disseminated copper sulphides, continuous for 95m (up to 0.06% copper) from 66m downhole (TLC170).
The current drilling will test for an increase in concentration of this copper mineralisation at depth.
The Programme will also test at depth similar magnetic features located within the Project including a cigar shaped anomaly only 800m SE of the EM5 Target and which may be related to the EM5 rocks from SE trending lineaments in the magnetics. Drilling will also test a circular magnetic anomaly in the north of the Project known as ‘Hot Spot’.
Hiding Maggie Magnetic Target
The Hiding Maggie target is an E‐W oriented untested magnetic rock unit with a number of elevated magnetic centres, seemingly a late magnetic intrusive, that coincides with a district scale E‐W linear feature in the magnetics that could be a large shear zone. All these features are covered by recent sedimentation and weathering and so have no surface expression.
The major E‐W lineament is coincident with the orientation of the Tollu sub‐basin and the interpreted rifting responsible for the Tollu volcanic package.
A strong near surface airborne EM anomaly that also trends across the E‐W lineament, probably related to the recent cover sequence, hides any potential EM anomaly that may exist at depth. Drilling will aim to identify and characterise the geology and test the magnetic intrusive and its contacts with the surrounding rocks for copper or nickel‐cobalt‐copper mineralisation potential.
Tollu Copper Vein Deposit
Following on from the success of the initial phase of shallow RC drilling undertaken at the Chatsworth and Forio Prospects in late 2021.
it is planned to further test the Tollu Copper vein system with deeper drilling in similar locations. Drilling will focus on testing extensions of the high-grade copper mineralisation at Forio and in the central area of Chatsworth.
It is expected that the second phase drilling will take approximately 5 weeks to complete. Although in‐field hh‐pXRF results will be available, long delays at geochemical laboratories within Australia make forecasting the return of assay results difficult. Redstone looks forward to updating the market as the Programme advances.
