CHILE – Vancouver-based LUMINA COPPER CORP. says that an independent mineral resource estimate makes its Regalito porphyry deposit in Region III the fifth-largest leachable copper discovery in this country made in the last 35 years.

In a report prepared by AMEC (PERU), the measured and indicated resources total 628 million tonnes grading 0.43% Cu, and there is an inferred resource of 131 million tonnes at 0.41% Cu. Further measured and indicated resources of 215 million tonnes grading 0.21% Cu and inferred resources of 60 million tonnes grading 0.20% copper at a cut-off grade of 0.15% have also been delineated. These ore tonnages are suitable for leaching. The Regalito deposit also contains unexplored primary mineralization at depth.

Lumina began work at Regalito in December 2003, and so far it has conducted over 32,000 metres of diamond drilling and various metallurgical tests. A preliminary leaching flowsheet has also been drawn. In 2005 the company will focus on the economic viability of a 150,000-tonnes/year copper cathode operation.
