THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported a drilling update from the Falcon zone within the company’s Hemi gold discovery near Port Hedland in Western Australia.
De Grey Mining carried out aircore drilling at the new Falcon intrusion, located approximately 600 metres west of the Brolga deposit and immediately south of the Aquila deposit.
The drilling encountered a broad mineralised zone extending from 800m to more than 1,000m along strike and 300m below surface at Falcon.
31 metres at 3.3 grams per tonne gold from 101m.
Tis intersection was achieved 50m downdip of a previous intersection of 50m at 3.3g/t gold from 50m in HERC265.
Mineralisation is interpreted to remain open across strike and down dip.
Elsewhere 42m of sulphide altered intrusion containing visible gold was intersected in HERC402D, extending mineralisation 50m – 100m below a previous intersection of 25m at 2.2g/t gold from 124m in HERC256.
Mineralisation is open down dip of HERC402D and up dip of HERC256.
Other intersections encountered along the mineralised zone include:
74m at 0.9g/t gold from 88m and 31m at 1.3g/t gold from 209m; and
32m at 2.4g/t gold from 43m and 8m at 5.5g/t gold from 99m.
De Grey claimed the intrusion to be now defined by aircore drilling over approximately three kilometres in strike.
Strong mineralisation has been defined over a strike length of approximately 1km with bedrock mineralisation covered by approximately 30m to 40m of transported material, similar to the Aquila, Brolga and Crow deposits.
“Falcon was identified as a separate intrusion zone at Hemi in September,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.
“The company has been following up the initial positive shallow aircore drill results with infill and extensional RC and diamond drilling.
“The latest results demonstrate the gold endowment of this zone along a strike of 1,000 metres and to a depth of at least 300 metres.
“Mineralisation remains open down dip, along this strike and up dip on some sections.
“Falcon has the potential to provide an important contribution to the overall gold endowment at Hemi.
“Extensional RC and diamond drilling will remain a focus at Falcon.
“The company has seven drill rigs operating on site; two aircore rigs, three RC rigs and two diamond rigs.
“A third diamond rig is being mobilised and is expected to commence by early December.
“As well as delineating the existing zones at Hemi, aircore and RC drilling is now progressively expanding to known and new intrusive targets in the Greater Hemi area.”
