Figure 1: Rig 43 from DDH1 Drilling on site drilling ASD-1

ASD-1 is planned for a vertical depth of +3,300m and designed to test the many rock sequences in the Pilbara Basin from surface and deep into the basement’s geology.

DDH1 Drilling have completed mobilising all their equipment to site and have now commenced 24 hour diamond drilling operations (Figure 1). The current drilling rate has reduced to 20m/shift from 40m/shift and is expected to increase again, as at 500m the core size was reduced from PQ to HQ.

The drill core from the hole is being moved from the drill site to Artemis’s Radio Hill Operations, located some 43 km to the north, where core is being logged and photographed. The round trip to move core is taking some 7 hours as care is being taken to not damage the core while in transit on unsealed roads. This is delaying the logging and reporting of lithology to coincide with depth reporting on Tuesdaymornings.

The whole core will then be sent to the GSWA’s Perth Core Library for analysis.

ASD-1 is located on E47/3707 (co-ordinates 480100mE, 7637370mN, 330m RL, Azi: 180, Dip: -85 degrees, Estimated Depth: 3,300m), some 43km south of Artemis’ Radio Hill Mine in the West Pilbara, of Western Australia. (Refer to previous Artemis news release, dated 22 March 2018 for further details on ASD-1).
