Blue Spec Shear diamond drilling programme
Northwest Resources Limited (Northwest) is pleased to announce that the Company has commenced a
diamond drilling programme at its high grade Blue Spec and Golden Spec gold-antimony deposits within the
company’s Nullagine Gold & Antimony Project.
The drilling program comprises approximately 1,600m of diamond core drilling to be directed at the Blue
Spec Upper Zone, the Blue Spec Remnant Zone, and Golden Spec (see Figure 1).
Northwest has reported Mineral Resources for the Blue Spec Upper Zone and Golden Spec of:
Blue Spec Upper Zone:
89,000 tonnes grading 42.5g/t Au for 122,000 oz Au and 2.61% Sb
for 2,300 tonnes Sb
Golden Spec: 273,000 tonnes grading 8.5g/t Au for 75,000 oz Au and 0.84% Sb
for 2,300 tonnes Sb (including 49,000 oz @ 18 g/t Au)
The Company also has a Target Mineralisation for the Blue Spec Remnant Zone of 90,000 - 100,000 tonnes
grading 14-16g/t Au for 40,000 - 50,000 oz Au.
The diamond drilling programme is designed to recover a total of approximately 250kg of ore zone material
from the three domains which will be used for the first stage of a detailed metallurgical testwork programme
to be conducted for the Company by Como Engineers Pty Ltd and Amdel Mineral Laboratories.
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 programme is designed
to produce sample Au-Sb floatation concentrates from each of the domains. Assay analysis of the metal
content of the floatation concentrates will enable Northwest to advance its ongoing discussions with parties
interested in potential Au-Sb concentrate off-take and smelting arrangements with the Company.
The diamond drilling program is expected to take around 2 months to complete and the metallurgical
testwork programme will be undertaken concurrently with the drilling programme, with final testwork results
expected around 5 weeks following completion of the drilling programme.
