Lumina Intersects Exceptional Copper Grades at Taca Taca Copper-Gold-Molybdenum Project, Argentina

198 Meters Grading 1.06% Copper (1.30% Copper Equivalent), 187 Meters Grading 0.99% Copper (1.13% Copper Equivalent) and 84 Meters Grading 1.81% Copper (2.21% Copper Equivalent)

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 6, 2011) - Lumina Copper Corp. (TSX VENTURE:LCC) (the "Company") is pleased to announce the results of 5 new holes drilled as part of the ongoing exploration and development program at its 100% owned Taca Taca copper/gold/molybdenum deposit located in Salta province, Argentina. The results are highlighted by hole TTBJ11-14 that intersected 254 meters grading 0.95% copper, 0.20g/t gold and 0.02% molybdenum (1.20% copper equivalent(1)) including 198 meters grading 1.06% copper, 0.22g/t gold and 0.02% molybdenum (1.30% copper equivalent) and hole TTBJ11-16 that intersected 187 meters grading 0.99% copper, 0.10g/t gold and 0.013% molybdenum (1.13% copper equivalent) including 84 meters grading 1.47% copper, 0.10g/t gold and 0.014% molybdenum (1.61% copper equivalent). In addition, TTBJ11-17 intersected 84 meters grading 1.81% copper, 0.27g/t gold and 0.04% molybdenum (2.21% copper equivalent) within an overall intercept of 378 meters grading 0.74% copper, 0.14g/t gold and 0.02% molybdenum (0.94% copper equivalent).

Results from TTBJ11-14, 16 and 17 are collectively the highest continuous copper grades encountered to date at Taca Taca. Hole TTBJ11-16 is of particular interest in that it was drilled along the north-eastern margin of the high grade zone and ended in material grading 0.5% copper. Holes TTBJ11-16 and 17 have extended and confirmed the high grade zone in a north easterly direction. Due to the average grade and length of mineralization encountered, the high grade zone appears to extend further to the north and east than previously predicted. Hole TTBJ11-14 was drilled in the projected center of the known high grade zone and in conjunction with holes TTBJ11-16 and 17 has significantly increased the average known copper grade over that contained within the existing mineral resource estimate. Hole TBJ11-15 has demonstrated an extension of the deposit to the west. Hole TBJ11-18 did not intersect any significant mineralization and with TTBJ10-02 may have begun to define the limits of mineralization to the northwest.

Details of the relevant intercepts from the latest 5 holes are shown in the table below. A map showing the location of the new results in relation to historical drilling is attached to this news release

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 to the north. To date, 34 core holes totalling 18,171 meters have been completed. Four drill rigs are currently operating on the project (3 core and one RC). Two additional core drills and one RC are expected to arrive at Taca Taca within 2 weeks. The RC rigs are being used to pre-collar core holes to expedite the program and receipt of exploration results. RC drilling will also be used in exploring and delineating the gold and copper zones known to exist in the oxide 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 announced it had received 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 0.64% copper equivalent, containing 8.71 billion pounds of copper, 2.97 million ounces of gold and 333.70 million pounds of molybdenum(2). 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 ( and on SEDAR (

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.

(2) 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).
