Rumble Resources Ltd (ASX:RTR) has received significant gold and copper drilling results from its maiden reverse circulation (RC) drill program at the Munarra Gully copper-gold project in Western Australia.
Significant disseminated sulphide mineralisation in mafic intrusive rocks at the White Rose Prospect include:
• 22 metres at 1% copper from 29 metres coincident with 19 metres at 2.19 g/t gold from 33 metres; and
• 10 metres at 0.74% copper from 75 metres with 11 metres at 0.73 g/t gold from 75 metres.

The Munarra Gully project is located 50 kilometres northeast of the town of Cue within the Murchison Goldfields.
Rumble has confirmed significant copper-gold RC drill intercepts discovered in fine to medium grain orthopyroxenitic rocks, potentially representing a style of magmatic sulphide mineralisation that is known to host large copper systems in Brazil and South Africa.
Lag and grab sampling by Rumble has outlined over 8 kilometres of strike potential coinciding with a partly buried strong magnetic anomaly which has been inferred as the same host – orthopyroxenite.
All four RC drill-holes completed at the White Rose prospect returned strong copper-gold sulphide mineralisation in both oxide and primary zones.

Rumble technical director Brett Keillor said: “To have a significant copper-gold discovery with Rumble’s maiden RC drilling programme at Munarra Gully is exceptional.
“Discovering the copper-gold association with disseminated sulphides highlights the potential for economic copper-gold bearing mafic/ultramafic intrusive related mineralised systems.
“The mineralisation style bears close resemblance to known atypical magmatic sulphide systems worldwide where large world class copper (gold) deposits have been historically mined - the Caraiba Cu province in Brazil and the Okiep Cu province in South Africa are examples.”
