Dreadnought Resources Ltd released the results of its maiden reverse circulation (RC) drilling program at CRA-North, part of the Rocky Dam Gold-VMS Project located 45 km east of Kalgoorlie in Western Australia.
Drilling was designed to target a high tenor gold-in-soil anomaly located along a sheared contract between felsic volcanics and sediments. Thick, near surface, oxide gold mineralisation was intersected associated with gossanous quartz veining.
Mineralisation is interpreted to be striking NNW-SSE, dipping to the WSW and plunging north in line with the local foliation. Follow up drilling will be undertaken to the west to drill beneath the oxide mineralisation targeting fresh bedrock mineralisation.
“Our maiden drill results at CRA-North are highly encouraging with good widths and reasonable grades,” said Dean Tuck, managing director of Dreadnought Resources. “The bedrock mineralisation and potentially higher grades are interpreted to sit to the west and at depth beneath the recent intercepts. The thick shallow oxide mineralisation combined with ~300 m of strike and proximity to Kalgoorlie makes CRA-North an attractive target for further drilling as soon as logistically possible.”
CRA-North was defined by CRA in the 1990s as a 700-m long gold anomaly along a sheared contact of felsic volcanics and black shales. This work included shallow RAB drilling (average depth 24 m) and two diamond holes (average depth 200 m). The diamond drilling appears to have been ineffective with down hole surveys indicating a significant change off planned azimuth by 30 degrees.
The recent program tested a high tenor gold-in-soil anomaly located along a sheared contact between felsic volcanics and sediments to confirm the orientation of the mineralised structure. Three sections of scissor holes were drilled either side of the gold-in-soil and historical RAB drilling intercepts. An additional hole was drilled to the south to test thin east-west trending quartz veins exposed during earthworks. In total, seven holes for 1,212 m were drilled along 300 m of strike.
Drill results included 45 m of 0.6g/t Au, including 9 m @ 1.7g/t Au from 18 m depth; and 4 0m @ 0.2 g/t Au from 19 m depth. Dreadnought Resources next step is to collect one metre splits from the mineralised intercepts and then plan for additional follow up drilling to test for potential bedrock mineralisation dipping to the west.
