Sirius Extends Polar Bear god zone

THE DRILL SERGEANT: First pass reconnaissance drilling being conducted by Sirius Resources (ASX: SIR) has extended a zone of gold anomalism at the first gold targets being tested on the company’s 100 per cent-owned Polar Bear project.

Sirius has extended the main gold anomaly at Polar Bear several hundred metres, taking its strike extent to approximately 1.6 kilometres with a maximum width of about 800 metres.

Individual 4 metre drill samples grade up to 3.64 grams per tonne gold and the supergene anomaly is still open to the northeast and southwest.

Intersections from the latest reconnaissance drilling include:

–    12 metres at 0.85g/t gold from 32metres, including 4 metres at 2.41g/t gold from 40 metres;

–    12m at 0.65g/t gold from 40m, including 4m at 1.16g/t gold from 40m;

–    16m at 0.68g/t gold from 48m, including 8m at 1.05g/t gold from 52m; and

–    15m at 0.62g/t gold from 48m, including 8m at 0.99g/t gold from 52m.

The company explained this recent round of drilling was the third of several stages of reconnaissance drilling it has planned to test a number of targets within the Polar Bear project area, which is surrounded by the Norseman, St Ives and Higginsville gold camps that collectively host approximately 25 million ounces of gold.

“Broad spaced aircore drilling (400 metre x 40 metre) is used to define anomalous zones (defined by a threshold of greater than 0.1g/t, or 100ppb, gold) as a prerequisite to more detailed and deeper drilling of specific mineralised zones,” Sirius Resources said in its ASX announcement.

“It is particularly encouraging to extend mineralised zones with high concentrations of gold over such broad areas at this early stage of the program.

“Extension drilling is currently underway with first pass drilling of untested targets scheduled to commence following Heritage clearance later in the year.”

The company has also completed two diamond drillholes testing the Yardilla electromagnetic (EM) target it announced in July, which have intersected graphite and minor pyrrhotite (iron sulphide) at the target depth.

Sirius has completed a down hole EM (DHEM) survey, which it claims to have confirmed the EM conductor had been tested and the EM response was due to the presence of graphite and pyrrhotite.

The company indicated it intends, over the next several months, to continue with drilling to explore the Nova and Bollinger horizons within the Eye, the as yet undrilled Eyelet intrusion and the recently-defined Conductor 7 within the Mining Lease application area.

An electromagnetic (EM) survey is due to commence at the 100 per cent Sirius-owned Buningonia intrusion where anomalous nickel, copper, cobalt, platinum and palladium has already been confirmed in soil sampling.
