Redstone Resources (RDS) has begun a 3000-metre drilling program at the Tollu copper vein system and surrounding areas.

The reverse circulation (RC) program is the initial phase of the company’s broader exploration program at its West Musgrave project in Western Australia.

Redstone conducted drilling in 2019 which showed potential for the Tollu copper vein system to produce thick, high-grade copper mineralisation both shallow and at depth.

That program returned results including 13 metres at 3.04 per cent copper from 56 metres downhole, including eight metres at 4.4 per cent from 57 metres downhole.

It also previously undertook mapping and sampling which highlighted at least four prospective areas for future copper exploration.

The new drilling program will further test the vein system and test for a northern extension of the Chatsworth prospect at depth as well as the prospective areas — one of which spans one kilometre and will be prioritised.

The next phase of the exploration program will include deeper RC drilling to further test the anomalous copper at the EM5 target as well as two other EM5 ‘look‐a‐like’ magnetic anomalies.

EM5, is an electromagnetic target coincident with a large, circular magnetic anomaly located 7.2 kilometres northeast of Tollu. Drilling in 2019 intersected a large gabbroic intrusion bearing a thick sequence of anomalous, disseminated copper sulphides that continues for 95 metres.

Redstone said the program has the potential to add to the Tollu deposit’s existing copper resource of 3.8 million tonnes at one per cent copper for 38,000 tonnes.

Company shares were up 18.2 per cent to trade at 1.3 cents at market close.
