Previous early-stage explorers have included Barrick and Newcrest, with the latter's geologists reportedly noting similarities to the six million ounce-Gosowong project.

Walker told an investor webinar last week that Far East was very encouraged by what it had been observing in the core drilled and cut to date, with visible quartz breccia vein systems in all of the first eight holes and "really interesting base metal mineralisation" noted.

He also said the true width of the vein systems was up to 25-30m in parts, illustrating the significant scale potential.

The drilling is the first on the broader project ground since initial exploration by Barrick in 1997.

Undrilled prospects being targeted by Far East are multiple kilometres in length, with geophysics undertaken and bonanza grade rock chips recovered.

Far East has three rigs in action.

The company listed in March following an A$11.7 million IPO.

In addition to Woyla it has two other projects in Indonesia, Trenggalek and Wonogiri.

Trenggalek is seeing as analogous to Tuju Bukit - site of major gold-silver operation - and Wongiri is a more advanced 1.15 million ounce gold-equivalent opportunity where previous scoping work is to be updated.

Meanwhile, precisely because Far East has substantial Indonesian operating experience, the company has Queensland exploration projects in its portfolio to take up the slack should unforeseen hold-ups happen in the island archipelago.

Various work programs on the Queensland ground have been completed and are continuing.   

At a share price of 66c, Far East was capitalised this week at $142 million.
