(MENAFN - ProactiveInvestors - Australia) Thundelarra Exploration (ASX:THX) has had success drilling at Curara Well in the "hot" Doolgunna region of Western Australia.

RAB drilling intersected significant copper, nickel and chromium anomalism.

Thick intervals of up to 40 metres copper mineralisation were intersected at greater than 20 times background (>700ppm up to 1,060ppm).

Significant to note, the results are from shallow depths.

Visual inspection of the most significant intervals indicated the presence of magnetic mineral, coincident with copper, nickel and chromium anomalism in what could be a mafic-ultramafic unit.

The anomalies are located adjacent to the Jenkins Fault zone of influence (the "DeGrussa Trend") which marks the tectonic contact between the Proterozoic Bryah Basin to the south-east and the Archaean Marymia-Plutonic Greenstone Belt to the north-west.

There are two schools of thought that could explain the presence of the mafic-ultramafic rocks intersected by the drilling.

One, the rocks belong to the Narracoota Formation (host to Sandfire Resources' (ASX:SFR) DeGrussa deposits), and are similar to occurrences near Gayle's Bore, and at Talisman Mining's (ASX:TLM) Halloween Project, west of the Great Northern Highway.

If so, they are the most north-easterly occurrence of the prospective VMS horizon identified to date along the DeGrussa Trend.

Second, the rocks are an extension of the older Marymia-Plutonic greenstone belt which is mapped occurring immediately to the north-east on the fringes of the Curara Well Project area.

This greenstone belt hosts the Plutonic Gold Mine, which has produced just under 5 million ounces since operations commenced in 1990.

If this scenario proved correct, it would represent substantial potential for gold mineralisation. This possibility is supported to some extent by the intersection in hole TCWRAB040 of 43ppb gold over 4m.

Further, deeper, follow-up drilling will be required.
