Far East Gold has received more positive news out of Indonesia, with the government giving its formal approval on air emissions and the company yielding promising results from epithermal sample metallurgical test work at its Wonogiri Project site.

The junior explorer announced this week that it had received environmental technical approval for air emissions associated with the development and operation of its proposed mine at the Wonogiri Project from the Indonesian Government.

This approval is a significant milestone for advancing the Wonogiri Project’s Randu Kuning sub-outcropping porphyry deposit through the remaining environment permitting processes that will ultimately allow the development and operation of a copper and gold mine on the site.

The company further announced that a high-grade sample in recent test work had high gold recoveries of 96%, most of which was due to a high gravity recoverable gold (GRG) extraction of 75%. The corresponding overall silver recovery was 65%, of which about half was due to gravity alone.

This indicates that most of the gold contained within epithermal type mineralisation can be recovered efficiently, which Far East Gold believes should improve cash flow and lower operational cost.

This is partly due, the company noted, to less chemical reagents needed for the downstream processes, which in turn supports the explorer’s environmental policies.

Previous leaching testwork on Wonogiri porphyry samples has found that between 35% and 51% of the gold can be recovered to a gravity concentrate, and that 83-85% of the gold in the gravity tailings can be recovered using conventional carbon-in-leach cyanide leaching.

The overall gold recoveries ranged from 90-91%. The associated silver recovery was about 65%.

Positive news out of Woyla, too

Further north at Far East Gold’s other major Indonesian project, Woyla, petrographic studies have confirmed the presence of free gold associated with sulphides in samples of vein material collected from the Anak Perak, Rek Rinti, Aloe Eumpeuk and Aloe Rek low sulphidation epithermal vein systems.

The company has also recently completed upgrades to Woyla’s critical site infrastructure, including its access roads to enable the mobilisation of drill rigs, and signed a contract with Omega Drilling for the first phase of the drill program at Anak Perak.

The program – which includes a target of 10 holes totalling about 1400m of diamond core drilling – is intended to be carried out with the Indonesian Government’s Ministry of Energy and Mineral Resources, which is currently completing Induced Polarisation Survey works at the site.

These updates follow an earlier announcement that Far East Gold has concluded a Conduct and Compensation Agreement (CCA) with the landowners at Hill 212 – its highly prospective gold epithermal project in Queensland’s Drummond Basin.

The CCA agreement allows the company to begin advanced exploration work at the site, including drilling, and to continue with the exploration work for the remainder of Hill 212’s exploration permit term, which ends on 21st November 2026.
