RMA Energy (ASX:RMT) has started an airborne geophysical survey over its Macauley Creek Project area west of Townsville, Queensland, that will bring focus to its 2012 field work.
The 10,929 line kilometre survey will take 10 days to complete and will acquire magnetic and radiometric data over the tenement.
It will also include measurements made for potassium, thorium and uranium.
Drilling at Macauley Creek in early September 2011 had encountered mineralisation in all 3 sections drilled.
The mineralised structure appears to range in thickness from 1 to 5 metres and grades of up to 51 grams per tonne silver, 2% zinc, 2.5% lead and 0.4% copper were encountered.
RMA added the mineralisation was found to be hosted in granite and appeared to be located in broad zones rather than being hosted by discrete lode-type structures.
The company held cash of just over A$1 million at 31 December 2011.
