Centerra can earn a 70% interest in the 253 km2 Project area by investing a total of $9.0 million in exploration on the property before December 31, 2020.
On the Siuna Project in addition to the historic trend highlighted by the La Luz Deposit (past production of 2.3 million ounces gold) and the Cerro Aeropuerto Inferred resource (707,000 ounces gold and 3.1 million ounces silver) the results from the La Luz soil grid also defined a second gold trend, the Cerro Coyol - El Tiburon Trend, which has been traced for 3.8 km. Within the Northern Siuna area existing gold targets include; Montes de Oro, Mina Victoria, Cerro Aza, and Roskilete,
The La Luz Project is located in the south-west portion of the Borosi Concessions and contains the past producing open pit and underground La Luz Mine that produced 17.1 million tonnes of ore grading 4.14 g/t gold (2.3 million ozs gold) as well as, one kilometre to the south, the NI43-101 compliant Inferred Resource at the Cerro Aeropuerto gold-silver deposit which hosts 707,750 ozs gold and 3.1 million ozs silver in 6.05M tonnes grading 3.64 g/t Au and 16.16 g/t Ag at a cut off of 0.6 g/t (see Calibre News Release dated February 28, 2011).
Notes: - Mineral Resources that are not mineral reserves do not have economic viability.
- The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.
