Lachlan Fold Belt
Rock Lodge
The Rock Lodge prospect is located 20 kms south of Cooma in southern NSW. The prospect exhibits significant gold mineralisation associated with structurally controlled epigenetic massive sulphide veins. The grades intercepted during historical drilling show the area to be highly mineralised and the mineral assemblages are synonymous with other major mineral deposits within the Canberra to Cooma region of the Lachlan Fold Belt.
The East Lachlan Fold Belt has a long history of mineral production including gold (80 Mozs), copper (13 Mt), lead, zinc, silver and tin. It contains several large operating copper and gold mines including Evolution Mining’s Lake Cowal Gold Mine, Newcrest Mining Ltd’s giant Cadia Mine. Also located within the East Lachlan Fold Belt is Alkane Resources’ 2019 market moving Boda discovery (502 metres at 0.2% copper and 0.48 g/t gold from 211 metres).
Rock chip sampling of outcropping quartz veins at Rock Lodge by historical workers returned assay results of up to 11.1g/t Au. Follow up drilling intersected massive sulphides with recorded grades up to 4.28g/t Au, 35g/t Ag, 0.79% Cu and 13.5% Zinc.
The intersections from Catalina’s drill holes in 2022, SRLRC002 to SRLRC005 in addition to previous drilling by Alt Resources (holes MYRC001-6), constitute a very wide (60m) mineralised envelope of stacked vertical lenses of significant polymetallic sulphide (Figure 1). Diamond Drilling conducted in Nov 2024 ( Assays awaited) , intersected broad zones of alteration with intervals of sulphide veining and quartz-sulphide veining and brecciation hosted by siltstone.
Two hundred meters to the north, IP anomalies and similar anomalous rock chip geochemical signatures, suggest the mineralisation envelope may be continuous at least to this area.
