INVESTMENT HIGHLIGHTSCALIBRE INVESTMENT HIGHLIGHTS CALIBREMINING.COM 3
• NICARAGUA: stable government, mining favourable political environment, long history of foreign investment in the mining sector
• MINING TRIANGLE: Calibre’s 785 km2 Borosi gold-silver-copper project is located in one of the most prolific mining districts in Central America with over 7.9M ozs of past gold production yet the district remains largely underexplored
• PARTNERSHIPS: Calibre has formed two partnerships with two mid-tier gold producers B2Gold and IAMGOLD and also a third partnership with Alder Resources whereby Calibre’s partners are required to spend up to $12 million on exploration and development over the next 3 years
• CALIBRE GOLD RESOURCES: Calibre’s 100% owned NI 43-101 Inferred Resources total 1,057,750 ozs gold and 8,430,070 ozs silver in three deposits
• CALIBRE 100% OWNED MONTES DE ORO GOLD PROJECT: trenching has delineated significant widths of gold mineralization including 52.3 metres grading 7.1 g/t gold and 27.5 metres grading 4.93 g/t gold within a 400 metre by 650 metre gold-silver-copper-zinc soil anomaly
• 2014 EXPLORATION/DEVELOPMENT PLANS: B2Gold: trenching/auger sampling at the Minnesota gold project, IAMGOLD: exploration drill programs at Riscos de Oro and Guapinol, Alder: further testing Rosita Cu-Au-Ag surface enriched and oxide targets

1. CIM definition standards were followed for the resource estimate.2. The 2012 resource models used Inverse Distance grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids. 3. A base cutoff grade of 0.6 g/t AuEq was used for reporting resources with capping of silver grades at 591 g/t.4. A density of 2.65 g/cm3 was applied.5. Numbers may not add exactly due to rounding.6. Gold Equivalent (AuEq) calculated using $1264 /oz Au gold and $19.78/oz Ag silver and metallurgical recoveries and net smelter returns are assumed to be 100%.7. Mineral Resources that are not mineral reserves do not have economic viability.8. 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.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.6. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred mineral resources as indicated or measured mineral resources and it is uncertain if further exploration will result in upgrading them to indicated or measured mineral resources.
