RMA Energy (ASX: RMT) has discovered new zones of mineralisation at the Macauley Creek Project, west of Townsville in Queensland, with rock chip samples returning up to 200 grams per tonne (g/t) silver and 1% copper.
The rock chips are part of a field program designed to follow up on more than 30 geophysical targets identified in a geophysical survey early this year.
Results for 51 rock chip samples have been received to date, indicating the presence of hydrothermally altered rocks that feature base and precious metal mineralisation.
In addition to copper and silver, the rock chip samples have returned up to 1% zinc, 0.5% lead and 0.1g/t gold.
Discoveries of altered and mineralised rocks coincident with magnetic anomalies defined by the geophysical program are continuing.
Drilling at Macauley Creek in early September 2011 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.
RMA is continuing field mapping and will assess the results once all data is collated.
