Calibre has agreed to purchase back Centerra's 51-per-cent interest in the Siuna gold-silver-copper property located in northeastern Nicaragua. In consideration, the company will issue two million shares to Centerra. Under the NSR agreement, Centerra will retain a 2-per-cent NSR on production from the property, though Calibre has the right to purchase 1 per cent of the NSR for $2-million and has been granted a first right of refusal on the remaining 1 per cent.
