    Artemis Resources reports deep gold-copper discovery below Carlow Castle resource

    Artemis Resources Limited (ASX: ARV, Frankfurt: ATY, US OTCQB: ARTTF) announced that a high-grade potential feeder zone was discovered below the current resource from the ongoing drill programmes on its Carlow Castle project in Western Australia.

    The company said that the first assays from deep diamond drill holes at Carlow Castle have identified high-grade gold and copper well below the existing 2019 JORC Resource envelope.

    ARV said that the drill hole 20CCAD003 discovered a high-grade potential feeder zone 525m below surface, 250m vertically below the current resource, with results including 4m @ 11.1g/t Au, 2.0% Cu, 0.18% Co from 639m.

    The company said that these assays from the bottom half of 20CCAD003 are the first received from a near complete 48-hole, multi-rig Diamond and RC drill programme. More than 90% of assays submitted to date are still pending with many due soon.

    Artemis said that the drill hole 20CCAD003 also discovered an upper high-grade gold zone, possibly representing a totally new northern parallel lode.

    The company said that an additional 551m infill hole (20CCAD007) was completed to confirm vertical up dip continuity of both new discovery zones. The assays are pending.

    ARV said that the diamond drill programme is ongoing, while the step out RC programme has been completed.

    The company said that a detailed AMAG survey was completed and final data sets processing is underway. ARV said that an IP crew is due on site soon to complete 10 line dipole-dipole programme over the existing resource and new discovery areas in advance of 10,000m follow-up RC drilling programme to commence in early December.

    Carlow Castle project

    The Carlow Castle Project is located in the West Pilbara region of Western Australia. In March 2019, the company had announced a JORC Resource update, which grew the resource by 71% based on 2018’s drilling to an Inferred Resource of 7.7Mt @ 1.06 g/t gold, 0.51% copper and 0.08% cobalt for 260,000oz Au, 38,000t Cu and 5,900t Co.

    Significant deposits within the Carlow Castle project include the Carlow Castle deposit, Quod Est deposit, and Carlow Castle South deposit.

    The Carlow Castle South Au-Co-Cu deposit is hosted by east-west shears in basalt and ultramafics. Oxidation of the primary mineralisation occurs to depths of 25-65 m below the surface. The Quod Est Au-Cu-Co deposit is hosted by north-south shears immediately north of Carlow Castle South in basalt with oxidation of the primary mineralisation down to an estimated 25-40 m below the surface.

    Drilling at Carlow Castle

    The company had commenced Diamond Drilling Campaign and RC Drilling Campaign at the Carlow Castle Project. The company said that the 32-hole reverse circulation (RC) drilling programme has been completed, while 60% of the diamond drilling programme has been completed.

    Artemis has now announced the intersections from the very first DD hole, 20CCAD003. The diamond drill hole 20CCAD003 was targeted at intersecting the system at approximately 600m vertical depth and 250m below the previous deepest mineralised intercepts.

    The company noted that these assays from the bottom half of 20CCAD003 are the first received from a near complete 48-hole, multi-rig Diamond and RC drill programme. More than 90% of assays submitted to date are still pending with many due soon.

    High-grade results below MRE

    ARV said that the Diamond drill programme is ongoing, 6 infill and extensional diamond drill holes for 2,131m have been completed and samples put in for assay. 6 holes remain to be completed for 1,020m.

    New mineralised zone

    Artemis announced that the diamond drill hole 20CCAD003 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.

    The company said that the analytical results for the lower NQ size core are complete and show the main mineralised zone continues to about 630m vertical depth.

    Significant results from the bottom half of 20CCAD003 are noted below.

    Artemis said that the high-grade result is hosted within the gabbroic dyke and the main zone mineralisation is hosted within altered chloritic basalts. The company speculates that this could be a feeder zone from the main 2019 JORC Resource mineralisation, however further drilling is required to confirm that.

    ARV said that the drill hole 20CCAD003 also discovered an upper high-grade gold zone, possibly representing a totally new northern parallel lode, the size of which will be determined when remaining upper hole assays are received.

    The company noted that a 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.

    New DD hole 20CCAD007

    The company said that due to the visual results of 20CCAD003, a second hole, 20CCAD007 was drilled. ARV said that the additional 551m infill hole (20CCAD007) was drilled to confirm vertical up dip continuity of both new discovery zones. Diamond hole 20CCAD007 finished prematurely due to technical issues but did transverse most of the target zone.

    ARV said that 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 company said that upper of these zones are hosted within the gabbro and the lower is within altered basalts.

    RC programme completed

    ARV reported that a 32-hole step out RC programme for 4,156m at Carlow Castle was completed with the primary objective to identify new shallow zones of mineralisation. The company said that the first assays are expected by early-December.

    The company said that a detailed AMAG survey has been completed and an IP survey programme is due to start soon in advance of a further 10,000m of follow-up RC drilling to begin early December.

    What’s next?

    The company said that the results at the Carlow Castle Co-Cu-Au project warrant further drilling and the drill programme results to date are considered excellent. Artemis said that an IP programme and detailed low-level aeromagnetic survey are scheduled to be completed in the coming weeks.

    Artemis announced that the company is expecting results from the RC drilling programme and further diamond core results to continue to flow from today through to January 2021.

    Management comments

    Artemis’ Executive Director Alastair Clayton said: “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. 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.”
