THE DRILL SERGEANT: St George Mining (ASX: SGQ) is about to commence a major diamond and RC (reverse circulation) drill program at the company’s Mt Alexander project near Leonora, in the North-eastern Goldfields of Western Australia.
St George Mining said the planned drill program will consist twenty planned drill holes for 2,510 metres of drilling with further drilling to be undertaken as drill results are assessed and downhole EM (DHEM) surveys on completed drill holes are reviewed.
Most of the planned drill holes are to be carried out at the Stricklands prospect where drill hole MAD71, completed late last year, returned the best intersection the company has encountered to date at the Mt Alexander project
The thick ultramafic channel at Stricklands was originally identified by MAD49, which intersected:
18.86 metres at 0.42 per cent nickel, 0.16 per cent copper, 0.02 per cent cobalt and 0.36 grams per tonne total PGEs from 31.8m; and
3.36m at 2.09 per cent nickel, 1.18 per cent copper, 0.09 per cent cobalt and 1.82g/t total PGEs from 50.66m.
MAD71 was subsequently drilled to the north of MAD49 and also intersected the prospective ultramafic unit at shallow depth but with a much thicker high-grade nickel-copper sulphide intersection including more than eight metres in aggregate of massive nickel-copper sulphides.
Follow-up drilling completed by Sy George last year at Stricklands continued to intersect the mineralised ultramafic, which the company interpreted as an east-northeast oriented ultramafic channel.
The company said the drilling it has completed to date indicates the mineralised channel may extend over 400m.
“Drilling in 2017 at Mt Alexander intersected thick massive nickel-copper sulphides at each of the Stricklands, Investigators and Cathedrals prospects,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“We are excited to be commencing our 2018 drill program at Mt Alexander to follow-up on last year’s success.
“At Stricklands, nine drill holes were completed last year to follow-up the outstanding intersection in MAD71 and of those seven drill holes intersected nickel-copper sulphide mineralisation.
“The high strike rate provides confidence that further drilling at Stricklands will continue to identify mineralised ultramafic.”
The company indicated its planned drilling at Stricklands for 218 will continue to test for extensions to the mineralised ultramafic, particularly where it considers it to be co-incident with the strongest portion of a large SAMSON EM anomaly.
