GOLD/COPPER PROJECTS
Calibre and B2Gold have a joint venture which gives B2Gold the right to acquire an
additional 19% interest (70.0% total) in the Primavera gold-copper project and surrounding
Borosi concessions totalling 322 km2 by spending CDN $6.0 million on exploration over 3
years. (Which began September 2013). At the Primavera gold-copper Project past drilling
intersected significant porphyry-style mineralization including: 261.7 metres grading 0.78
g/t Au, 0.30% Cu. Additional channel sampling in 2013 returned high grade results from the
Minnesota gold project including: 9.2 metres grading 4.17 g/t Au. An exploration program
managed by B2Gold continues on a series of targets with recent trench results from the
Minnesota gold project including: 109 metres grading 1.58 g/t Au and 8.5 m grading 1.22
g/t Au.
GOLD/SILVER PROJECTS
Calibre Mining Corp. and IAMGOLD Corporation have signed an Option Agreement
whereby IAMGOLD can earn a 51.0% interest and subsequently an additional 19.0%
for a total of 70.0% interest in the Eastern Borosi Project (the “Project”) consisting of
176 km sq within the Borosi Concessions, Northeast Nicaragua. The Eastern Borosi
Project hosts gold-silver resources in two deposits and a series of well defined low
sulphidation epithermal gold-silver targets. To earn a 51.0% interest in the Project
IAMGOLD must pay Calibre $450,000 and invest $5.0 million in exploration on the
property over three years. Once vested at 51.0% IAMGOLD can elect to earn an
additional 19.0% of the Project for a total of 70.0% by paying Calibre an additional
$450,000andbyinvesting$5.0millioninexplorationontheProjectoverasubsequent
three year term. IAMGOLD and Calibre completed a successful $1.5M 2014 drilling
campaign, including drill intercepts of 4.8m @25.7 g/t Gold & 35.0 g/t Ag and 6.5m @
16.9 g/t Au & 20.9 g/t Ag, and the Phase II $1.5M 2015 drilling program is underway.

1. Au Eq cutoff equivalent calculated using Wardrop’s estimated gold price
of US$1058/oz and silver price of US$16.57 per ounce.
2. Mineral resources that are not mineral reserves do not have economic viability.
3. Metallurgical recoveries and net smelter returns are assumed to be 100%.
The Calibre Borosi concessions are located approximately 275 kilometres northeast of the capital city of Managua and 80 kilometres west of the coastal town of Puerto Cabezas.
The concessions cover 78,525 hectares (785km2) of the highly prolific but underexplored Mining Triangle of northeastern Nicaragua. Calibre has entered into one joint venture
and two option agreements with B2Gold Corp, Alder Resources Ltd. and IAM Gold Corp covering 532km2 of the 785km2 Borosi concessions (68%). Calibre has maintained control
of the 253 km2 Siuna Project concessions which includes the NI43-101 Cerro Aeropuerto Inferred Mineral Resource and the high priority Cerro Potosi (La Lu Mine) and Montes de
Oro prospects (details can be found in the relevant sections ).

1. Base case is reported at a 0.15% copper equivalent cut-off grade which incorporates consideration of mining and processing cost, recoveries, commodity prices and selling cost.
2. Estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of US$24/oz.
3. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences.
4. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy ounces, contained copper pounds as imperial pounds.
5. 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.
CALIBRE MINING’S PARTNERSHIPS
GOLD/SILVER/COPPER/ZINC PROJECT
Calibre has discovered new gold-silver-copper-zinc
mineralization at the Montes de Oro target, North of the
Cerro Aeropuerto gold-silver resource. Sampling on this
new discovery has returned some of the highest gold
grades in the district and additional exploration work is
planned. Calibre has a current work program underway
GOLD/SILVER/COPPER/ZINC PROJECT
Calibre has 100% ownership of the 253 km2 Siuna
District which hosts a variety of gold-Skarn, porphyry
and epithermal vein targets. Most notable is the past
producing La Luz Mine which produced 2.3 million
ounces of gold from 7.0 million tonnes grading 4.14g/t
gold during its operation from 1912-1968. Other targets
defined by Calibre include Cerro Aeropuerto (skarn),
Montes De Oro (skarn), La Virgin (skarn-porphyry), Casa
Blanca and El Avion (epithermal veins).
GOLD/SILVER PROJECTS
Calibre’s third agreement within the Borosi Concessions has granted Alder Resources an option to earn a 65%
interest in the 33.6km2 Rosita D Concession by spending $4.0 million on exploration over four years and by issuing
to Calibre a total of 1,000,000 Alder common shares by 2015. Alder and Calibre have a compliant NI 43-101 Inferred
