Results of extensional drilling completed this year at the Falcon, Brolga, Aquila, Crow and Diucon/Eagle zones show that De Grey’s (ASX:DEG) mammoth Hemi discovery has potential to get a lot bigger.
Strong gold mineralisation at the Falcon intrusion, ~600m west of Brolga and immediately south of Aquila, has now been defined over a strike length of ~1km north-south.
Drilling has pulled up a strongly mineralised 90m intersection from 492 to 582m downhole; 180m vertically below a previously reported 26.3m long intersection grading @ 2.3g/t gold.
The deeper drilling demonstrates a thick zone (~45m true thickness) of sulphide mineralisation, with assays pending.
Mineralisation dips steeply to the east, extends to at least 500m depth and remains open at depth and along the current 1km of strike, De Grey says.
“The latest extensional drilling at Falcon confirms the increasing scale and continuity of the zone,” managing director Glenn Jardine says.
“Wide sulphide mineralisation has now been intersected to approximately 500m and remains open at depth.
“Step out diamond drilling will continue at depth along the current 1000m long strike at Falcon.”
Other new intercepts like 72m at 1.6g/t also extend shallow mineralisation to the north of Falcon towards Aquila.
Fresh infill drilling results at Falcon include 45m at 1.5g/t gold from 175m and 41m at 2.2g/t gold from 61m.
“Results of infill drilling announced this year increasingly confirm continuity of mineralisation at each deposit and in the case of Crow, has identified multiple new sub-vertical lodes,” Jardine says.
The Falcon intrusion itself also extends for a further 2km south, as confirmed in shallow wide-spaced aircore drilling.
“Deeper RC drilling to more effectively test this large target area in more detail is planned for the current quarter,” Jardine says.
