Northwest focuses with Blue and Golden Specs

/in /by

THE DRILL SERGEANT: Northwest Resources has commenced a diamond drilling program at the Blue Spec and Golden Spec gold-antimony deposits located within the company’s Nullagine gold & antimony project in the eastern Pilbara of Western Australia.

The drilling program is set to undertake approximately 1,600 metres of diamond core drilling, which will be directed at the Blue Spec Upper Zone, the Blue Spec Remnant Zone, and Golden Spec deposits.

Northwest has previously reported Mineral Resources for the Blue Spec Upper Zone and Golden Spec deposits.

Blue Spec Upper Zone:

–    89,000 tonnes grading 42.5 grams per tonne gold for 122,000 ounces of gold and 2.61 per cent antimony for 2,300 tonnes antimony.

Golden Spec:

–    273,000 tonnes grading 8.5g/t gold for 75,000 ounces of gold and 0.84 per cent antimony for 2,300 tonnes antimony, including 49,000 ounces at 18 g/t gold.

The company has also outlined a Target Mineralisation for the Blue Spec Remnant Zone of 90,000 tonnes to 100,000 tonnes grading 14 g/t to 16 g/t gold for 40,000 ounces to 50,000 ounces of gold.

Northwest said it has designed the diamond drilling program to recover a total of approximately 250 kilograms of ore zone material from the three domains.

This will be used for the first stage of a detailed metallurgical testwork program.

“In addition to providing Northwest with information on gold and antimony recovery which will be used in process flow design evaluation and capital cost estimates, the metallurgical test work program is designed to produce sample gold-antimony floatation concentrates from each of the domains,” Northwest Resources said in its ASX announcement.

“Assay analysis of the metal content of the floatation concentrates will enable Northwest to advance its ongoing discussions with parties interested in potential gold-antimony concentrate off-take and smelting arrangements with the company.”

Northwest said it expects the drilling program will be completed in around two months with the metallurgical testwork program being undertaken at the same time.

The company anticipates it will have final testwork results ready around five weeks following the completion of the drilling program.
