Crystallex International Corp., a Canada-based gold mining company, said Tuesday, it planned to sell five-year bonds worth a total of as much as $120 million.

 Macquarie Capital (USA) Inc., GMP Securities L.P. and Byron Capital Markets Ltd. are co-lead agents for the offering.

The bond offering comes a few days after the Toronto Stock Exchange asked Crystallex for information to help the bourse determine whether the company meets continuing listing requirements.

Crystallex operates gold mines in Venezuela, which recently nationalized those properties.
