Lumina Exercises Option to Acquire Taca Taca

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 24, 2005) - Lumina
Copper Corp. (TSX:LCC)(AMEX:LCC) is pleased to announce that it has
entered into an agreement with Corriente Resources, Inc. ("Corriente")
to exercise early, its option to acquire the Taca Taca property in
Argentina. In lieu of making final payment of 100,000 shares and US$1.1
million in cash as per the original agreement, Lumina has issued 200,000
shares to Corriente and is now owner of 100% of Taca Taca.

The Taca Taca property, consisting of 13 mining concessions (2546
Hectares), is located in the Puna region of northwest Argentina, in
western Salta province. The property contains a very large Andean type
"porphyry copper" hydrothermal system that has generated a significant
amount of supergene and hypogene copper and gold mineralization. Copper
mineralization was first recognized on the Taca Taca property in the
1960's. A total of 24,033 meters of reverse circulation and diamond
drilling in 156 holes have been completed on the property. A NI 43-101
Technical Report by AMEC has estimated a historical mineral resource of
240 million tonnes grading 0.41% copper at a 0.2% copper cutoff grade.

Upon completion of Lumina's proposed reorganization in May 2005, Taca
Taca will be held by one of Lumina's successor companies, Global Copper
Corp. Ongoing work at Taca Taca will include the evaluation of the
potential for much larger oxide and supergene mineralization by
additional drilling.
