The objective of the tightly-spaced ground gravity survey is to provide data that can be modelled with modern 3D inversion techniques to better define drill targets.
Results from the ground gravity surveys and the previously completed mobile metal ion sampling campaign are expected by the end of this month, Greatland said in a statement on Tuesday.
"The ground gravity survey at Havieron represents an important step towards defining drill targets for a drilling campaign currently scheduled for early 2018,” said Gervaise Heddle, chief executive officer of Greatland.
"We believe that the Paterson region, host to Newcrest's Telfer gold mine, is highly prospective for multiple large mineralised systems, as demonstrated by our further commitment to the region with the acquisition of the Black Hills gold project announced yesterday," he added.
Shares in Greatland were up 3.8% at 1.87p in lunchtime trading.
