Estrella Resources (ASX:ESR) began a mobile magnetotellurics unmanned aerial vehicle (UAV) passive electromagnetic geophysical survey at its Ira Miri manganese project in East Timor, according to a Tuesday Australian bourse filing.
The survey is designed to investigate extensions to the known manganese mineralization and determine if a larger mineralized system is present. The system acquires near-continuous passive electromagnetic data with effective sampling intervals of around five meters, per the filing.
