De Grey Mining Drilling at Pilbara Gold Project

/in /by

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) has a Reverse Circulation (RC) drill rig operating on the Mallina prospect, at the company’s Pilbara gold project near Port Hedland in Western Australia.

Ge Grey Mining said the planned drilling program is aimed at expanding resources, which currently stand at 18.9 million tonnes at 1.7 grams per tonne gold for 1.02 million ounces of gold.

The main targets of the RC drilling program include:

Mallina – a four-kilometre-long gold target, which has previously yielded encouraging shallow wide spaced drilling results including:

4m at 9.11g/t gold
6m at 3.79g/t gold
7m at 5.45g/t gold
23m at 2.52g/t gold
3m at 12.49g/t gold and
29m at 1.7g/t gold

Mt Berghaus – a five-kilometre-long anomaly with defined resources of 3.5 million tonnes at 1.2g/t gold for 141,000 ounes that remains open with 3km of the anomaly still to be drill tested.

Withnell Trend – a twenty-kilometre-long gold trend with defined resources of 9.2 million tonnes at 1.8g/t gold for 538,000 ounces that remain open.

Ge Grey has identified a number of walk-up drill targets it claims exist between the existing deposits and along parallel structures where very limited drilling has been completed.

Drill intercepts, not included in the current existing resources to be followed-up include:

7m at 1.59g/t gold
17m at 2.07g/t gold
38m at 1.07g/t gold
6m at 5.32g/t gold and
16m at 2.01g/t gold

“At Mallina, the drilling program comprises an initial program of 80 holes for approximately 6,000 metres and is designed to infill and confirm continuity of gold mineralisation between existing drill holes and also the potential for multiple stacked gold lodes,” De Grey Mining said in its ASX announcement.

“Drilling commenced last week, with 22 holes currently completed for a total of 1,556 metres.

“The first batch of samples have been dispatched to the laboratory with all results pending.

“Geological logging indicates the mineralisation is associated with alteration along the margins of a series of porphyry intrusions and quartz veining within a sequence of siltstone and shales.

“This style of mineralisation is similar to that observed at Mt Berghaus.”
