Last week, Greatland reported that it had identified a Western Zone 6km in length and 1.5km in width and an Eastern zone 2km by 1.5km.
Several of the zones were up to 60 metres thick and reasonably shallow.
A new more detailed analysis of the cores has indicated gold grades of up to 2 g/t with silver also present in some cores.
It was the first wide-spaced drill campaign at Greatland’s 100% owned Ernest Giles licence.
Greatland is targeting 5mln ounce deposits and clusters of one million ounces.
The surrounding region is host to the Tropicana discovery, which contains over 7mln ounces and Yamarna with over 6mln.
