The drill program is focused on defining a higher grade zone within the known NI 43-101 compliant mineral resource estimate as well as expanding known mineralization at depth and to the north. To date, 38 core holes totalling 21,373 meters and 15 reverse circulation holes totalling 2,366 meters have been completed and 4 drill rigs are currently operating on the project (3 core and one RC). Two additional core drills and one RC are expected to arrive Taca Taca in August. The RC rigs are being used to pre-collar core holes to expedite the program. RC drilling will also be used in exploring and delineating the gold and copper zones known to exist in the leach cap of the Taca Taca porphyry system.
The Taca Taca copper/gold/molybdenum project, comprising approximately 2,500 hectares, is located in the Puna region of north western Argentina in Salta Province, approximately 230 kilometres west of the provincial capital of Salta and 90 kilometres east of the world's largest copper mine, Escondida.
On October 9, 2008, the Company released an independent National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate for the project that at a 0.4% copper equivalent cutoff contained inferred mineral resources of 841 million tonnes grading 0.47% copper, 0.11g/t gold and 0.018% molybdenum (0.64% copper equivalent(3)), containing 8.71 billion pounds of copper, 2.97 million ounces of gold and 333.70 million pounds of molybdenum. This mineral resource estimate does not incorporate or reflect the drilling results described above.
Additional information on Taca Taca, including the NI 43-101 technical report "Amended Taca Taca Technical Report" dated January 22, 2010 by Robert Sim, P.Geo., can be found on the Company's website (www.luminacopper.com) and on SEDAR (www.sedar.com).
Andrew Carstensen, CPG, Vice President, Exploration and the Qualified Person as defined by NI 43-101 for the Taca Taca project has reviewed and approved the content of this press release.
(3) The copper equivalent cut off grade used in the calculation of the mineral resource estimate was determined using US$1.50 / lb copper, US$600 / oz gold and US$9.00 / lb molybdenum and was not adjusted for metallurgical recoveries as these remain uncertain. The formula used in the calculation was as follows: CuEQ = Cu% + (Au g/t x 0.583) + (Mo% x 6).
