Lumina Copper Receives US$2 Million Advance Royalty Payment From Coro Mining for San Jorge Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 7, 2010) - Lumina Copper Corp. (TSX VENTURE:LCC) ("Lumina" or "the Company") is pleased to announce that it has received a US$2 million payment from Coro Mining Corp. ("Coro") as part of that company's US$16 million advanced copper royalty payment in connection with its option to purchase Lumina's San Jorge copper/gold/molybdenum project in Mendoza Province, Argentina.

Under the terms of the option agreement, Coro is required to make advance payments of US$2 million in 2010, US$4 million in 2011 and US$5 million in 2012 and 2013 against future copper royalty payments less the aggregate deemed value of 1 million shares previously issued to Lumina. However, if Coro completes a Bankable Feasibility Study after May 2011 then the company is obligated to pay the remaining outstanding amounts owing within six months from the date of completion of the Bankable Feasibility Study.

The US$16,000,000 payment is an advance payment on either: (a) the obligation to pay $0.02 per pound on the mineable proven and probable copper sulphide reserves upon commencement of commercial production or (b) the obligation to pay $0.025 per pound on the mineable proven and probable heap leachable copper reserves upon commencement of commercial production. For any production of copper in excess of that derived from the total sulphide and heap leachable mineable proven and probable reserves, Coro will pay $0.015 per pound of copper contained in ore processed by a mill and $0.02 per pound of copper contained in ore placed on leach pads. In addition to the copper royalty, Coro has also issued Lumina a net smelter royalty of 1.5% on all other metals to be mined including gold and molybdenum.

With the payment, Lumina's cash balance has increased to $6.5 million.
