LUMINA INTERSECTS 586 METERS GRADING 0.97% COPPER EQUIVALENT INCLUDING 280 METERS GRADING 1.23% COPPER EQUIVALENT IN STEP-OUT HOLE AT TACA TACA COPPER-GOLD-MOLYBDENUM PROJECT, ARGENTINA

Lumina Copper Corp. has released results from seven new holes drilled as part of the continuing exploration and development program at its 100-per-cent-owned Taca Taca copper/gold/molybdenum deposit located in Salta province, Argentina. Results are highlighted by step-out hole TT11-35 that intersected 586 metres grading 0.77 per cent copper, 0.13 gram per tonne gold and 0.02 per cent molybdenum (0.97 per cent copper equivalent), including 280 metres grading 1.09 per cent copper, 0.14 gram per tonne gold and 0.01 per cent molybdenum (1.23 per cent copper equivalent). Hole TT11-35 was drilled 150 metres to the north of hole TT11-26 and 75 metres outside the 0.4-per-cent-copper-equivalent shell of the known National Instrument 43-101-compliant mineral resource estimate.

In addition to increasing the mineral resource's grade and size laterally, hole TT11-35 also extends mineralization an additional 320 metres below the NI 43-101 mineral resource estimate in the immediate area. Likewise, holes TT11-31 and TT11-34 drilled in the same northern zone have increased mineralization to depth by 230 metres and 350 metres, respectively. Hole TT11-37, drilled 140 metres beyond the northern boundary of the NI 43-101 mineral resource estimate, has extended mineralization in that direction, while hole TT11-33, drilled along the southwestern boundary of the NI 43-101 mineral resource estimate, increased the depth of mineralization in this area by an additional 290 metres.

Drilling continues to identify additional oxide gold and copper in the leached cap. Hole TT11-32, drilled near the eastern boundary of the NI 43-101 mineral resource estimate, intercepted 181 metres grading 0.31 gram per tonne gold and hole TT11-37 intercepted 100 metres grading 0.25 per cent copper.

Details of the relevant intercepts from the latest seven holes are shown in the attached table.

(1) Copper equivalent calculated using $2 (U.S.) per pound copper, $800 (U.S.) per 
    ounce gold and $12 (U.S.) per pound molybdenum, and is not adjusted for
    metallurgical recoveries as these remain uncertain. The formula used is as 
    follows: copper equivalent equals copper plus (gold multiplied by 0.583) 
    plus (molybdenum multiplied by 6).                      

The drill program is focused on defining a higher-grade zone within the NI 43-101 mineral resource estimate, as well as expanding mineralization to depth, and to the north and south. To date, 57 core holes totalling 31,080 metres and 38 reverse circulation holes totalling 6,970 metres have been completed. Five drill rigs are currently operating on the project (four core and one reverse circulation). Two additional drills, one core and one reverse circulation will arrive by the end of the week. Reverse circulation drill rigs are being used to precollar core holes to expedite the program, as well as to explore and delineate the gold and copper zones known to exist in the leached 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 northwestern 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 Oct. 9, 2008, the company released an independent NI 43-101-compliant mineral resource estimate for the project that at a 0.4-per-cent-copper-equivalent cut-off contained inferred mineral resources of 841 million tonnes grading 0.47 per cent copper, 0.11 gram per tonne gold and 0.018 per cent molybdenum (0.64 per cent copper equivalent), 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 in this press release.

Additional information on Taca Taca, including the NI 43-101 technical report, "Amended Taca Taca Technical Report," dated Jan. 22, 2010, by Robert Sim, PGeo, 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.

Note: the copper equivalent cut-off grade used in the calculation of the mineral resource estimate was determined using $1.50 (U.S.) per pound copper, $600 (U.S.) per ounce gold and $9 (U.S.) per pound molybdenum, and was not adjusted for metallurgical recoveries as these remain uncertain. The formula used in the calculation was as follows: copper equivalent equals copper plus (gold multiplied by 0.583) plus (molybdenum multiplied by 6).
