Hawthorn Resources Limited announced that to the Market on 30 June 2021 and following the grant of a POW by the W.A. DMIRS the Company, on 2 July 2021, commenced a 600m Reverse Circulation (RC) drill campaign to investigate potential extensions of mineralisation into Hawthorn's M31/481, which is contiguous to Gibb River Diamond's Neta Project, with the Carlsen lode as the focus of the RC drilling campaign. The program of Reverse Circulation drill holes, conducted from 2 to 4 July 2021, completed testing the area immediately south of the recently discovered Carlsen Lode made by Gibb River Diamonds in air core drilling last October. The six-hole program for 612 meters showed only weak intercepts in the southern extension of this lode. The best grade intersections of 1.32g and 4.74g were made in hole 21EDRC002 drilled just south of the Mining Lease boundary with the GIB lease. A wider intersection was seen in hole 21EDRC004 of low-grade quartz-pyrite mineralised lode grading 0.45g between34 and 35 meters and a deeper lode of 0.5g over 2 meters between 46-48 meters. It appears that the Carlsen lode has weakened south along strike from GIB hole AC013.
