SSR Mining Inc. is offering US$200 million of unsecured convertible senior notes due 2039, it said March 12.

The company plans to grant the initial purchasers an option to purchase up to an additional US$30 million of the notes.

SSR Mining will use the proceeds to repurchase a portion of its outstanding 2.875% convertible senior notes, and for general corporate purposes.

The notes will bear a semiannual cash interest at a fixed rate and can be converted into company shares. The notes are also redeemable in certain circumstances.

SSR Mining and the initial purchasers will determine the final terms of the offering.
