To discuss results of a preliminary economic assessment on Taca Taca project in northwestern Argentina

Lumina Copper Corp. announced the results of a Preliminary Economic Assessment on its 100% owned Taca Taca copper/gold/molybdenum project located in the Puna region of Salta Province in northwestern Argentina. The results of the PEA show that a mining and sulfide concentrating operation at Taca Taca has favorable economic potential generating, at an 8% discount rate and $2.75/lb copper price, an estimated after tax net present value of $2.1 billion and an estimated after tax internal rate of return of 17.2%. Highlights of the Study's various estimates are as follows: Robust Project economics driven by a large mineral resource base, a higher grade starter pit and excellent regional infrastructure supporting a lower than average capital intensity ratio on initial capital. An estimated after tax NPV of $2.1 billion, at an 8% discount rate, and an estimated after tax IRR of 17.2%. Assumed long term metal prices of $2.75/lb copper, $1,200/oz gold and $12/lb molybdenum. Average life of mine copper production of approximately 244,000 tonnes per year over a 28 year mine life. LOM gold production will average 110,000 ounces per year, while molybdenum production will average 4,100 tonnes per year. Copper production over the first seven years of the mine's life will average 271,000 tonnes per year with a peak in year two of 349,000 tonnes of copper. C-1 LOM cash costs estimated to average $1.11 per pound of copper sold. Initial capital of $3.0 billion and total LOM sustaining capital of $1.8 billion. The sustaining capital includes the addition of a third mill and flotation line and associated infrastructure and equipment to the concentrator during the sixth and seventh years of production. A capital intensity ratio on initial capital of $11,090 per tonne of average annual copper produced for the first seven years of production. Capital payback on initial capital is expected to be 3.8 years after production begins. The Project is expected to generate approximately 1,100 full-time jobs. During the initial four years of pre-production, including 30 month concentrator construction period, approximately 1,300 direct jobs will be generated. The Project will potentially generate $9.5 billion in taxes and government royalties payable to the Argentine and Salta governments.
