Calibre and Centerra Gold Start 1500 Metre Drilling Program on the La Luz Project, Nicaragua

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 22, 2015) - Calibre Mining Corp. (TSX VENTURE:CXB) (the "Company" or "Calibre") is pleased to announce that the Company and Centerra Gold Inc. ("Centerra") have commenced the 2015 Drilling Program on the 12 km² La Luz Gold-Silver Project (the "La Luz Project") within the Borosi Concessions, Northeast Nicaragua.

Highlights

• Centerra Gold can earn a 70% Interest in the La Luz Project by investing $7.0 million in exploration on the property before December 31, 2019;
• The La Luz Project includes the past producing La Luz mine and the NI 43-101 compliant inferred gold resource at the Cerro Aeropuerto Project;
• The 2015 Drilling Program has started and is focused on the Cerro Aeropuerto Project with an estimated 1500 metres to be completed in 5 drill holes. The Inferred Resource at Cerro Aeropuerto gold-silver deposit contains 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.
• Additional exploration is on-going consisting of soil sampling, mapping, and geophysical surveying covering the entire 12km² La Luz Gold-Silver Project area.

President and CEO, Greg Smith stated: "Calibre is extremely pleased to have been able to start field activities and drilling so quickly following the signing of the agreement with Centerra. It is a testament to our in-country personnel and the support of the local governments and communities that we have been able to commence exploration and drilling in a timely manner. We look forward to unlocking the potential of this historic mining area."

The 2015 drilling program will consist of 1500 metres in five drill holes to be completed on the Cerro Aeropuerto Project. Drilling is designed to test the continuity and orientation of the previously identified primary gold-bearing structures. The drilling will test the mineralization over approximately 450 metres of strike length and between 100 and 250 metres below surface.

The Inferred Resource at Cerro Aeropuerto gold-silver deposit contains 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.

Additional exploration has been commenced which will cover the entire 12 km² La Luz Gold-Silver Project area. Work is consisting of soil sampling, geological mapping, and ground geophysical surveys. Field work was commenced in late September 2015 and to date more than 950 soil samples, approximately 85% of the projected total of 1100 samples, have been collected. The exploration program is designed to advance the two main mineralized trends on the Project; the La Luz - Cerro Aeropuerto, and Santa Rita - Tiberon Trends. A total of 15 targets have been identified through a combination of historical data review and surface sampling.
