13 Operations Report Operations Report Production for the year was 133,681 ounces of gold and 1,000,569 ounces of silver. Total mill throughput of 5.7 million tonnes was  11.4% higher than 2012 despite the 63 days that  the new plant was shut down during the process  for the granting of its Metallurgical License. The  overall plant availability was 98.1%. Total cash costs for the year were $US767 per  ounce ($US620 per ounce exclusive of Thai  royalties). The average royalty paid to the Thai  Government was $US147 per ounce of gold. Total  production costs after depreciation and amorti- sation were $US952 per ounce of gold produced.  At year end, 9.7 million tonnes of ore was stock- piled with an average contained gold grade of  0.57 grams per tonne (g/t) representing 178,086  ounces of gold. During the year 7.1 million tonnes of ore was  mined, with a waste-to-ore strip ratio of 2.09:1.  The average grade of mined ore was 0.72 g/t  gold and 8.56 g/t silver. Additional ore was generated by revising the  mining sequence in A Pit Stage 2 and accessing  near surface high grade oxide ore tonnes from Q Prospect. Total volume of material mined at Chatree for  the year was 8.4 million Bank Cubic Metres  ("BCM") including 2.7 million BCM of ore.  An additional 566,000 BCM of laterite and clay material was excavated and used for the  construction of the second lift of second tailings  storage facility (TSF#2). Some 1.3 million loose cubic metres (LCM) of  ore was relocated from the Marginal Grade  Stockpiles to the primary crusher to supplement  ore from the mining pits. Two areas were mined during the year: The mechanical reliability and hence availability  of the major fleet items has been below expecta- tions over the last few years.  continued Production and Costs Operational Performance 〉 A Pit, where 8.3 million BCM of material was  mined (2.7 million BCM of ore) at a stripping  ratio of 2.09:1 waste to ore; and 〉 Q Prospect where 298 thousand BCM of  material was mined (143 thousand BCM of  ore) at a stripping ratio of 1.1:1 waste to ore.
