Lumina Copper Corp. (TSX VENTURE:LCC) (the "Company") is pleased to
announce results from 12 new holes (holes TT11-38 - TT11-49)
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. Results are highlighted by hole 45
that intersected 734 meters grading 0.67% copper, 0.09g/t gold and
0.02% molybdenum (0.84% copper equivalent(1)), including 146 meters
grading 1.66% copper, 0.17g/t gold and 0.01% molybdenum (1.82%
copper equivalent). Hole 45 contains the longest mineralized
interval drilled to date at Taca Taca and was terminated due to
depth limitations of the drilling rig with the bottom 10 meters of
the hole averaging 0.55% copper. The hole is located within the
northeastern portion of the 0.4% copper equivalent(2) shell of the
known National Instrument 43-101 compliant ("NI 43-101") mineral
resource estimate. Hole 45 not only increases the average grade of
copper mineralization in the immediate area, but also extends known
mineralization an additional 400 meters to depth.
Holes 38 and 42 (a re-drill of hole 38) were lost in higher
grade copper mineralization and will be re-drilled. Hole 38
intersected 292 meters grading 0.78% copper, 0.13g/t gold and 0.01%
molybdenum (0.92% copper equivalent), including 150 meters grading
1.04% copper, 0.17g/t gold and 0.02% molybdenum (1.26% copper
equivalent). Hole 42 intersected 390 meters grading 0.64% copper,
0.11g/t gold and 0.01% molybdenum (0.76% copper equivalent),
including 164 meters grading 1.09% copper, 0.16g/t gold and 0.02%
molybdenum (1.30% copper equivalent).
Holes 45, 38 and 42 have confirmed that the high-grade copper
zone extends to the east by approximately 375 meters and remains
open in that direction. Holes 38 and 42 have also extended the
known mineralization in the immediate area 125 meters above that
defined by the current NI 43-101 mineral resource estimate.
Step-out hole 49, drilled 150 meters to the east of hole 16 (187
meters grading 1.13% copper equivalent) and 300 meters to the south
of hole 45 intersected 284 meters grading 0.85% copper, 0.08g/t
gold and 0.02% molybdenum (1.02% copper equivalent), including 182
meters grading 1.11% copper, 0.11g/t gold and 0.02% molybdenum
(1.29% copper equivalent). Hole 49 extended the known
mineralization an additional 60 meters above and 200 meters below
mineralization defined by the current NI 43-101 mineral resource
estimate in the immediate area. Mineralization remains open to the
east of hole 49.
Holes 40, 41 and 43 drilled 150 meters to the north-northwest of
the known NI 43-101 mineral resource estimate, have extended
moderate mineralization in that direction. Holes 47 and 48, drilled
within and along the western boundary of the northeastern portion
of the NI 43-101 mineral resource estimate have confirmed the
expected mineralization. Hole 39, drilled west of the fault that
defines the southwestern boundary of the NI 43-101 mineral resource
estimate, contains a long interval of lower-grade copper
mineralization.
Infill hole 46, drilled in the western section of the
higher-grade zone was lost in high-grade mineralization and will be
re-drilled. The hole intercepted 51 meters grading 1.14% copper,
0.25g/t gold and 0.03% molybdenum (1.47% copper equivalent).
The Company is completing an updated, interim NI 43-101 mineral
resource estimate that will include all results through hole 49.
The updated mineral resource estimate will be completed within the
next one to two weeks.
Drilling continues to identify additional oxide gold in the
leached cap and the updated mineral resource estimate will include
a preliminary estimate of the oxide gold resource. Hole 49
intercepted 144 meters grading 0.31g/t gold.
Details of the relevant intercepts from the latest 12 holes are
shown in the table below with locations shown in the map attached

(1) Copper equivalent calculated using US$2.00/lb Cu, US$800/oz Au and
US$12.00/lb Mo and is not adjusted for metallurgical recoveries as
these remain uncertain. The formula used is as follows: CuEQ = Cu% +
(Au g/t x 0.583) + (Mo% x 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, east and south. To date,
66 core holes totalling 36,612 meters and 45 reverse circulation
("RC") holes totalling 8,642 meters have been completed. Six drill
rigs are currently operating on the project (5 core and one RC).
Two additional core drills with greater depth capabilities are
expected to arrive by the end of the year. RC drilling is being
used to pre-collar 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
north western Argentina in Salta province, approximately 230
kilometres west of the provincial capital of Salta and 90
kilometers east of the world's largest copper mine, Escondida.
On October 9, 2008, the Company released an independent 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(2)), 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.
(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).
