We are planning to increase throughput capacity of Toka Tindung Project through continuous optimization programs. There are several optimization programs currently under consideration such as processing alternative material with lower grade, which can be done by Crusher Fine Screen method and plant expansion.
Processing plant at Toka Tindung started its operation since April 2011 with installed capacity of 1.7 Mtpa. Through running optimization initiative, the plant now operates with 2.0 Mtpa capacity. For maintaining growth, the management is studying several different scenarios with objective to increase the gold production by 10-20k oz annually and to accelerate processing plan of 14 mt of lower grade ore. Archi plans to increase Toka Tindung Project gold production to reach 180-200k oz per annum in 2016 and achieve improvement in economies of scale.
Wonogiri Project, Indonesia
Archi is committed to develop gold and copper project in Wonogiri, Java island, Indonesia. Previous exploration activities of Randu Kuning porphyry prospect has estimated JORC compliance mineral resources at 1.01 million oz of gold and 200 million pounds of copper. Those estimation represented resources of 1.54 million oz gold equivalent. The mineral resources still has large potential for further drilling that is necessary to test the maximum capacity of gold and copper mineralization.
Archi has 35% stake in Augur Resources Ltd. (Augur), an Australian listed company (ASX code:AUK) that focuses in developing mineral resources in Indonesia and Australia. Below are the project own by Augur;
Yeoval is a porphyry copper-gold system with near surface mineralisation. The Yeoval tenement covers an area of approximately 147 km2 within the Lachlan Belt of New South Wales.
The Collerina project is located 40 km south of Nyngan in central New South Wales, covering an area of 300 km2 within the Fifield Platinum Province. The tenement contains the Homeville nickel-cobalt deposit, which was discovered by Augur in 2008.
An initial scoping study of the Homeville deposit found that a net present value of the project of $50.9 million based on a 12.5% discounted cash flow and an operation producing the nickel equivalent of 5,150 tonnes per annum over a period of 10 years.
The Weelah tenement in New South Wales is prospective for gold and copper-gold porphyry and gold epithermal targets.
