CXB Calibre Mining Corp

Calibre Mining Corp. (TSX VENTURE:CXB) (the "Company" or "Calibre") is pleased
to provide an update on the Company's 100% owned gold-silver projects and
gold-copper projects under joint venture with B2Gold Corp. ("B2Gold")
(TSX:BTO)(NYSE MKT:BTG) and Alder Resources Ltd. ("Alder") (TSX VENTURE:ALR).
Calibre's Borosi Concessions are located in the historic Mining Triangle (the
"District") of northeast Nicaragua that has past production exceeding 8 million
ozs of gold. Calibre and our Joint Venture partners control 785 km2 of
concessions in this prolific mining district which remains largely underexplored
for porphyry gold-copper deposits, epithermal gold-silver systems and
gold-copper skarn mineralization. 


Highlights

100% Calibre Gold-Silver Projects



--  Calibre's projects contain a NI 43-101 Inferred Mineral Resources
    exceeding 1.05 million ounces of gold and 8.4 million ounces of silver
    in three deposits, 
    
--  Work continues on the Montes de Oro gold skarn project where recent high
    grade trench results include; 52.3 metres grading 7.1 g/t gold, 27.5m
    grading 4.92 g/t gold and 19.3 metres grading 2.71 g/t gold located

    been identified with surface rock sampling returning up to 42.46 g/t Au
    and 2,457 g/t Ag. 
    



Calibre's Joint Venture Projects 



--  Calibre (49%) and B2Gold (51%) continue to advance Primavera gold-copper
    joint venture where past drilling intersected significant porphyry-style
    mineralization including: 261.7 metres grading 0.78 g/t Au, 0.30% Cu, 
    
--  Calibre (49%) and B2Gold (51%) recently announced additional channel
    sampling results from the Minnesota gold-copper project including: 9.2

President and CEO, Greg Smith stated: "The Mining Triangle of northeast
Nicaragua is one of the most prolific mining districts in Central America.
Calibre continues to advance a number of exciting epithermal, porphyry and skarn
related gold systems on the Company's 100% owned concessions. In addition, the
B2Gold and Alder joint ventures are funding on-going exploration programs on
additional high priority gold and gold-copper targets within the Borosi
concessions. With $1.4 million in working capital and two joint venture partners
spending up to a total of $7.0 million over the next three years Calibre is well
positioned for building gold-silver resources and making additional gold
discoveries in this underexplored District." 


Calibre's Borosi Concessions Overview

Calibre's Borosi Concessions, in northeast Nicaragua include a 100% interest in
429 km2 of mineral concessions that contain a NI 43-101 Inferred Mineral
Resource in three gold-silver deposits (Cerro Aeropuerto, La Luna and Riscos de
Oro) at a 0.6 g/t AuEq cut-off of 10.75 million tonnes grading 3.06 g/t Au and
24.38 g/t Ag containing 1,057,000 ozs gold and 8,430,000 ozs silver. Calibre has
joint venture exploration programs underway with B2Gold on 322.3 km2 of
concessions, which includes the Primavera gold-copper porphyry discovery and the
Minnesota gold-copper target and with Alder on the 33.6 km2 Rosita
gold-copper-silver project which hosts a NI 43-101 Inferred Mineral Resource in
gold-copper-silver surface stockpiles at a 0.15% CuEq cut-off of 7.9 million
tonnes grading 0.46 g/t Au, 0.62% Cu and 9.20 g/t Ag containing 118,000 ozs
gold, 108 million lbs copper and 2.35 million ozs silver. 


Calibre (49%) and B2Gold (51%) Joint Venture

Calibre and B2Gold have a joint venture on 322.3 km2 of concessions, which
includes the Primavera gold-copper porphyry discovery, and the Minnesota
gold-copper project. 


On September 09, 2013 Calibre signed a definitive Joint Venture Agreement with
B2Gold granting B2Gold an option to acquire a further 19% interest for a total
70% by spending $6.0 million in additional project expenditures over 36 months.
Calibre currently controls a 49% interest in the Project, while B2Gold controls
a 51% interest and is project operator. The 2013 exploration program has focused
on detailed surface exploration north and west of the main Primavera gold-copper
porphyry zone which is designed to identify potentially faulted/offset
mineralization within the Primavera gold-copper system. Previous drilling at
Primavera intercepted significant widths of porphyry mineralization including
261.7 metres grading 0.78 g/t Au and 0.30% Cu. In addition, soil geochemistry,
pit sampling and a ground magnetics survey has been completed on the San Isidro
gold-copper target located 5 kilometres west of Primavera. San Isidro has a
similar geological, geochemical, and geophysical signature to the main Primavera
target. 


Additional work by B2Gold has included sampling of recently exposed small miner
workings on the Minnesota gold-copper target where channel sampling has returned
7.5 metres grading 3.93 g/t gold and 9.2 metres grading 4.17 g/t gold.


Calibre and Alder Joint Venture

Calibre and Alder entered into an option agreement whereby Alder can earn a 65%
interest in the 33.6 km2 Rosita gold-copper-silver project by spending $4.0
million on exploration on the Rosita project and by issuing to Calibre a total
of 1,000,000 Alder common shares by 2015. Past production from the Santa Rita
open pit gold-copper-silver mine was 305 million pounds of copper, 177,737
ounces of gold and 2.6 million ounces of silver. Significant drill intercepts
from Alder's work include; 65 metres grading 1.48 g/t Au, 0.20% Cu, and 2.0 g/t
Ag and 15 metres grading 15.82 g/t Au, 0.04% Cu, and 0.23 g/t Ag. Alder has
tabled a NI 43-101 Inferred Mineral Resource in surface, stockpiled material
from the former Santa Rita mine that contains 108 million lbs copper, 118,000
ozs gold and 2.35 million oz silver. (see Calibre News Release dated May 09,
2012).


Calibre's 100% owned Siuna District (Montes de Oro Gold Project)

The Siuna District is located in the south-west portion of the Borosi
Concessions and contains the past producing La Luz Mine that produced 17.1
million tonnes of ore grading 4.14 g/t gold (2.3 million ozs gold).
Approximately 1.0 kilometre south of the La Luz Mine Calibre has defined an NI
43-101 Inferred Mineral Resource, the Cerro Aeropuerto gold-silver deposit at a
0.6 g/t AuEq cutoff of 6.0 million tonnes grading 3.64 g/t gold and 16.16 g/t Ag
containing 707,750 ozs gold and 3.1 million ozs silver. Calibre has recently
announced a new gold discovery at the Montes de Oro gold project located 10
kilometres north of the La Luz Mine and to date Calibre has outlined a 400 metre
by 650 metre gold in soil anomaly at Montes de Oro where trenching results
include 52.3 metres grading 7.1 g/t gold, 27.5 metres grading 4.92 g/t gold and
19.3 metres grading 2.71 g/t gold (see Calibre News Release dated September 19,
2013 for further details). At Montes de Oro, gold-skarn target trenching has
defined two high-grade, sub-parallel gold mineralized zones each over
approximately 250 metres long and open in both directions. Additional trenching
is now underway along the Northern zone targeting soil samples located 150
metres southwest of the currently defined mineralized zones and on the northern
half of the main soil anomaly which has not to date been tested by trenching. 


Calibre 100% owned Eastern Epithermal District (Guapinol & La Sorpresa Gold trend)

The Eastern Epithermal District hosts the Riscos de Oro gold-silver deposit
where limited past gold and silver production came from open pit and limited
underground development. Riscos de Oro has a defined NI-43-101 Inferred Mineral
Resource estimate at a cut-off grade of 0.6 g/t AuEq of 2,159,000 tonnes grading
3.20 g/t Au and 59.67 g/t Ag (4.14 g/t AuEq) containing 222,300 ozs gold and
4,142,000 ozs silver (287,100 ozs AuEq.) (see Calibre News Release September 5,
2012). At Riscos de Oro the majority of the 7.0 km long gold-silver trend
remains open in all directions and largely untested by diamond drilling.
Significant trench results on the Riscos de Oro extension located 500 metres
north-east of the existing NI-43-101 gold-silver resource has returned 13.50
metres grading 3.26 g/t gold and 14.7 g/t silver. Calibre continues to advance
the +10km long Guapinol and La Sorpresa Gold trend located east of the Riscos de
Oro gold deposit with mapping and rock and soil sampling programs underway. The
Riscos de Oro, Guapinol and La Sorpresa gold projects combined are very similar
in strike length and have comparable geology and style of gold mineralization to
the nearby Bonanza Gold Mine which has past production and current reserves in
excess of 4.0 million ounces gold. A 90% interest in the Bonanza mine was
recently purchased by Mineros SA of Medellin, Columbia for $95.4 million. 


Updated maps detailing the result of the current exploration programs will be
posted on the Company's web site at www.Calibremining.com.
