Sirius extends Inky with copper – zinc hits

/in /by

THE DRILL SERGEANT: The first round of drilling conducted by Sirius Resources north and south along strike from known mineralisation at the Inky prospect on the company’s Youanmi project in Western Australia has intersected copper-nickel mineralisation.

In its announcement to the ASX, Sirius said the step-out drilling had demonstrated sulphide mineralisation may occupy a broad south plunging zone that has yet to be adequately tested by drilling.

Mineralisation is open north along strike, down dip and down plunge to the south.

Sirius drilled four reverse circulation (RC) to determine the trend of the mineralisation as a prerequisite to planning further deeper drilling.

Three holes were effective and two of these intersected sulphide mineralisation, while the fourth hole did not reach target depth due to difficult drilling conditions.

The company intends having another attempt at this hole once it is able to source an appropriate drill rig.

The drill intersections from the recent drilling include:

–    6 metres at 0.59 per cent copper and 3.3 grams per tonne silver from 88m, including 2 metres at 1.12 per cent copper, 0.2 per cent nickel and 5.9 grams per tonne silver from 92 metres; and

–    7m at 0.34 per cent copper and 2.8g/t silver from 56m.

Sirius also conducted two reconnaissance RC holes on a separate zone known as the Boundary Gossan situated approximately two kilometres southeast of the Inky prospect.

Drill intersections from this drilling include:
 
–    3m at 0.34 per cent copper from 25m; and

–    4m at 0.22 per cent copper from 30m.

The company also claimed the discovery of a new gossan near Shirley Bore in the northern part of the project area.

Rockchip samples collected from this gossan contain up to 2.01 per cent copper, 4.2g/t silver and 0.17g/t gold.

Sirius said it intends to conduct RC drilling to test further strike continuation of the Inky prospect, the Boundary gossan, and the Shirley Bore gossan.
