Greatland Gold plc (LON:GGP) said its drilling campaign at its Bromus project in southern Western Australia has extended the strike.
The company drilled two holes, testing downhole electromagnetic (EM) targets, and intersected silver, zinc and other elements consistent with volcanogenic massive sulphide (VMS) style systems.
Additionally, the results of the drilling campaign returned low levels of nickel sulphide.
As a result, the strike has been extended to 1.5 kilometres.
Greatland said work at Bromus will now focus on further delineation of these VMS-style systems.
There will be a review of further targets, including gold mineralisation that was recorded in historic drilling some 1.2 kilometres to the north of the latest drilling campaign.
Greatland said one additional target identified by the downhole EM survey conducted last year has still to be tested.
"There has been renewed interest in VMS style deposits in Western Australia after the demonstration of their potential at the DeGrussa deposit and historically at the Golden Grove deposit, a gold copper producer in Western Australia,” said Gervaise Heddle, chief executive officer of Greatland.
“VMS-style deposits can have significant value with their multiple commodities, particularly if they have associated precious metals; consequently, we intend the Bromus Project to focus solely on VMS style deposits and look forward to making progress and updating the market in due course,” he added.
