Dart on-target for high-grade structures and multiple reefs at VIC’s Rushworth

Microcap explorer Dart Mining NL (ASX:DTM) has been vindicated in the mineral systems model it has developed for the Rushworth Goldfield in northeast Victoria, with drilling at the site intersecting several zones of sulphide mineralisation, yielding grades beyond 8 grams per tonne of gold.

Dart had interpreted this mineralisation as being indicative of potential high-grade structures, and sure enough, the diamond drilling showed that sulphide zones surrounded large structures.

As indicative of this, one hole of drilling pulled up 0.24 metres at 8.8 grams per tonne from 56.2 metres downhole, an intersection from within a broad zone of sulphide mineralisation returning 7.1 metres at 0.75 grams per tonne from 50.8 metres.

Another intersection from the same hole revealed 3.6 metres at 0.44 grams per tonne from 161.8 metres, of sulphide mineralisation including pyrite, cubic pyrrhotite and acicular with arsenopyrite, with this including two higher grade sections of 0.2 metres at 2.87 grams per tonne and 0.3 metres at 1.45 grams per tonne.

Results from another hole have been interpreted as showing potential for multiple stacked, plunging reefs: and Dart is anticipating further assay results in the coming weeks.

Chairman James Chirnside said the confirmation of Dart’s mineralisation model for the Goldfied was an important achievement.

“Receiving high grade results from reef structures within zones of gold bearing sulphide
mineralisation is a key step to refining our mineral systems model of the project,” he said.

“Today’s results confirm our optimism surrounding the results from a potential stacked reef system at Growlers Hill and add a second prospective target zone within 500 metres at the Star of the West prospect.

“Importantly we are just getting started, with the Growlers Hill and Star of the West prospects being the first two targets drill tested, on a long list.”

The market responded well to the news, and at 11:50 AEDT, Dart shares were trading at 2 cents, a rise of 11.11% since the market opened.
