High-Grade Potential Feeder Zone Uncovered 525m Below Surface
Artemis Resources Limited (ASX:ARV) has identified high-grade gold and copper well below the existing 2019 JORC Resource envelope in its continuing drill programmes on its 100%-owned Carlow Castle project in the west Pilbara region of Western Australia.
Executive Director, Alastair Clayton, said drill hole 20CCAD003 discovered a high-grade potential feeder zone 525m below surface, 250m vertically below the current resource assaying at 4m @ 11.1g/t Au, 2.0% Cu, 0.18% Co from 639m.
“The targeting and successful discovery of high-grade gold and copper over 250m below the bottom of the 2019 MRE from our very first deep hole just highlights the potential size of the gold and copper mineralised system at Carlow Castle,” Mr Clayton, said.
“We feel exploration to date has only scratched the surface of what might be present. As such and despite only having around half the assays back from the first hole, we have, based on visual core inspections, followed up with 20CCAD007 to test for vertical continuity and 20CCAD008, 120m to the West, to test for strike continuity of this possible high-grade feeder zone.
“These are only the first few assays back from our multi-rig Carlow Castle exploration programme and we now expect regular assays and updates from today through to January 2021. Elsewhere in our portfolio we expect to provide a detailed update from our Paterson Central Project in early December.”
Mr Clayton said the 60% completed diamond drilling programme is already viewed as being extremely successful due to the intersections received from the very first hole.
Drill hole 20CCAD003 is a deep test of the mineralised system, aiming to intersect the system at approximately 600m vertical depth and 250m below the previous deepest mineralised intercepts.
20CCAD003 has identified an entirely new mineralised zone hosted within an adjacent gabbroic dyke of 4 m @ 11.1g/t Au, 2.01% Cu & 0.18% Co in the footwall to the previously known mineralisation. Analytical results for the lower NQ size core are complete and show the main mineralised zone continues to about 630m vertical depth.
The high-grade result is hosted within the gabbroic dyke and the main zone mineralisation is hosted within altered chloritic basalts.
Mr Clayton said this could be a feeder zone from the main 2019 JORC Resource mineralisation, however further drilling is required to confirm that.
Given the visual results of 20CCAD003 a second hole was drilled (20CCAD007); processing of this core has been completed and assays are awaited, however, sulphidic zones have been identified in the inferred up-dip positions of the mineralised zones. The upper of these zones is hosted within the gabbro and the lower is within altered basalts.
Another feature of 20CCAD003 was numerous very fine-grained chert units hosting disseminated pyrrhotite (1-2%); it is unknown if these units are potentially mineralised and how they relate to the Carlow Au-Cu-Co mineralised system.
