TSX reviewing Constellation Copper shares

TORONTO, May 2 (Reuters) - The Toronto Stock Exchange is reviewing the shares of Constellation Copper CCU.TO to determine whether the firm's financial condition still merits its listing, the company said on Friday.

Constellation, whose shares have fallen 99 percent over the last two years, said it has been given 30 days to demonstrate compliance with TSX listing requirements.

The Denver-based company said in March it had defaulted on C$1.9 million of interest due on C$69 million of unsecured debentures.

It also said it was mulling alternatives, including a sale of the company, seeking alternate financing or filing for creditor protection if it cannot resolve its liquidity problems.

Constellation lost $116 million in 2007.

Its share were unchanged at 2.5 Canadian cents on the Toronto Stock Exchange on Friday. ($1=$1.02 Canadian) (Reporting by Cameron French; editing by Rob Wilson)
