      Lumina Copper Starts Drill Program at Taca Taca
      Copper/Gold/Molybdenum Project
=======================================================================

Vancouver, British Columbia - Lumina Copper Corp. (the "Company") is
pleased to announce that it has initiated a drill program at its 100%
owned Taca Taca copper/molybdenum/gold deposit located in Salta
province, Argentina in early May 2010.  The first phase of the program,
utilizing one drill rig capable of drilling to depths in excess of 1.2
kilometres, is designed to evaluate the deep targets generated from the
TITAN24 geophysical survey as well as expand the known zone of higher
grade copper mineralization within the existing mineral resource to the
northeast. 

The initial phase of the drill program is expected to last between 4
and 6 months but could be expanded and lengthened based upon early
drill results. 

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.

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).

Leo Hathaway, P.Geo., Vice President, Exploration for the Company 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.
