Borosi Gold, Silver and Copper
concessions
The 100% Calibre owned Borosi concessions cover over 785 square kilometres in northeastern Nicaragua. The Mining Triangle has been one of the most prolific mining
districts in Central America with a rich history of mining. Calibre has a NI 43-101 compliant inferred resource totaling 1,057,750 ounces of gold and 8,430,070 ounces
of silver on the 100% owned Cerro Aeropuerto, La Luna and Riscos de Oro Prospects and a NI 43-101 compliant inferred resource totaling 118,000 ounces of gold,
2,350,000 ounces of silver and 108,000,000 pounds of copper on the Rosita Prospect which is subject to a joint venture with Alder Resources.
BOROSI CONCESSION highlights
> Historical estimates of production from the
region:
• Gold, 7.9 million ounces
• Silver, 4 million ounces
• Copper, 305 million pounds
> Since acquiring Borosi concessions in 2009,
Calibre has advanced a number of key
prospects
> A portion of the Borosi concessions is party to an
agreement with Nicaragua’s largest gold producer,
B2Gold Corp.
> Results of extensive district scale exploration program
to-date:
• Completed 18,091.31m of diamond drilling (68 holes)
• Assayed over 1,791 rock samples and 9,773 soil samples
• Constructed over 2,244.68m (132 trenches) of trenches
• Completed surveying and reconnaissance mapping
over 516 km2
> B2Gold has earned 51% interest in these concessions
(322 sq. km) by funding $8 million in exploration
expenditures. They have an option to go up to 70% by
spending an additional $6M over 3 years.
MONTES de Oro (100%)
Primavera
Rosita
Calibre has recently discovered new gold-silver-copperzinc mineralization at the Montes de Oro target, North of
the Cerro Aeropuerto gold-silver resource. The company
is very excited about this new discovery and additional
exploration work is underway.
Calibre, in conjunction with B2Gold, continues to
advance Primavera gold-copper project. Primavera is
the site of a significant gold and copper soil anomaly
covering an area of 800 by 300 metres (open). An
approved phase I $2.0M exploration program is
underway including additional step out and infill
drilling as well as drilling additional gold/copper soil
geochem anomalies that have been outlined in the 25
km2 Primavera porphyry target area.
Calibre optioned the Rosita D concession to Alder
Resources Ltd., Alder may earn a 65% interest in
the Rosita D concession by spending $4 million
on exploration. Phase 1 exploration program
commenced Dec 2011 which includes 5,000m of RC
drilling and 8,000m of diamond drilling.

> Partially tested a strong gold-silver-copper anomaly
extending over a 400 by 650 metre area which remains
open to the northeast.
> Discovery trenching Highlights include:
• MTR13-009 - 52.3 metres grading 7.1 g/t gold
• MTR13-017 - 23.0 metres grading 5.35 g/t gold
Riscos de Oro (100%)
gold/silver project
Calibre has completed over 9,400 metres
of diamond drilling (37 holes) at the 100% owned Riscos
de Oro Epithermal Gold-Silver Project. The program has
successfully confirmed gold-silver mineralization over a
strike length of 725 metres and to a depth of 300 metres.

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.
