ASX-listed Collerina Cobalt Limited said it is nearing completion of an AMDAL study (environmental impact study) for the Randu Kuning gold‐copper deposit at the Wonogiri gold and copper project in Indonesia?s Central Java Province.

Collerina said in a statement on Tuesday that on acceptance of the AMDAL, the company will be awarded a 20‐year operation production IUP (with 10‐year extension) for the Randu Kuning gold‐copper deposit.

Separately, the company said it is ready to initiate an Environmental Management Efforts and Environment Monitoring Efforts (UKL‐UPL) report for its planned aggregate operation adjacent to the Randu Kuning deposit. Upon approval the company will be granted an initial 5 year aggregate operation license, which can be extended for two additional 5 year terms.

At the Wonogiri project, Collerina Cobalt is advancing the Randu Kuning gold‐ copper porphyry deposit which contains 1.15 Moz gold equivalent1 JORC compliant mineral resource estimate for Randu Kuning deposit comprising:
? 996,521 ounces of gold (53% Measured and Indicated category); and
? 190M pounds of copper (43% Measured and Indicated category).

The company said metallurgical testwork results indicate up to 89.0 percent recovery of gold and 93 percent of copper is possible via flotation, with potential for 55 percent recovery of gold from simple gravity concentration.

As previously reported, the company has received approval of its feasibility study from the Indonesian Ministry of Mines & Energy for development of a gold only operation at Wonogiri.
