Augur Resources (ASX: AUK) has a focus on gold and copper within Indonesia and nickel projects within Eastern Australia. Augur’s key projects are the Wonogiri gold-copper project in central Java, Indonesia and the Jampang gold-copper project in western Java, Indonesia.
Augur Resources delivers more wide gold intersections at Wonogiri
Further drilling by Augur at the Wonogiri project in Central Java has revealed 95.5m at 0.74g/t gold and 0.16% copper from only 41m, indicating high grade zones may be viable targets within the Randu Kuning porphyry system.
Augur Resources (ASX: AUK) has received more results from diamond drilling at the Randu Kuning porphyry prospect within Wonogiri project in Central Java.
Hole WDD019 returned significant mineralisation including 95.5 metres at 0.74 grams per tonne (g/t) gold and 0.16% copper from only 41 metres.
The intersection includes a high grade zone of 5 metres at 5.08 g/t gold and 0.50% copper from 82.0 metres and a further 66 metres at 0.47 g/t gold and 0.11% copper.
This high grade zone indicates that high grade zones may be viable targets within the Randu Kuning porphyry system.
This latest broad intersection is significant as it points to the bulk tonnage potential, while drawing comparisons to some major nearby deposits.
The hole was drilled to test for mineralisation below hole WDD012 where 199 metres at 0.46 g/t gold and 0.13% copper was previously intercepted.
Another hole, WDD020, was drilled to test depth extension of the main Randu Kuning zone and intersected two zones of significant mineralisation including 96 metres at 0.54 g/t gold and 0.13% copper from 43 metres and a further 29 metres at 0.63 g/t gold and 0.10% copper from 246 metres.
The company said that interpretation of the drill core has concluded that the Randu Kuning prospect "consists of multiple porphyry intrusives indicating a prolonged intrusive history."
Extensive alteration may be indicating a deeper mineralising source which has yet to be drill tested.
In another important development for the company, initial metallurgical results have returned favourable recoveries with up to 88.7% of gold recovered and 96.1% of copper recovered in sulphide samples.
The company will undertake further testing in coming months with a focus on determining an appropriate process for recovery of minerals in the oxide zone and gravitational testing for further improving the gold recovery.
There are a number of significant porphyry deposits in the region of Wonogiri, with Newmont Mining Corporation’s (ASX: NMC) operation at Batu Hijau which hosts 914 million tonnes at 0.53% copper and 0.40 g/t gold, sitting along the same zone as Augur's project.
Providing a further prospectivity boost to the region is Newmont’s Elang deposit on the island of Sumbawa, and Intrepid Mines (ASX: IAU) Tujuh Bukit in eastern Java, which hosts 990 million tonnes at 0.40% copper and 0.45 g/t gold.
Three drill rigs are still actively drilling at Wonogiri with a new plus 1,000 metre drill depth capacity rig expected by the end of November that will test for deeper high grade zones located on the flanks of the porphyry intrusions.
Deep drill hole targets have been finalised, based on the most recent geological model, where there is potential for high grade mineralisation.
