CXB Calibre Mining Corp

Calibre Mining Corp. (TSX VENTURE:CXB) (the "Company" or "Calibre") is pleased
to provide an update on activities at the 100% owned Montes de Oro gold project
within the Siuna District, Borosi Concessions, northeast Nicaragua. 


Highlights



--  Calibre has now completed 552.1 linear metres of trenching at the Montes
    de Oro gold project which has defined two sub-parallel zones (Northern
    and Southern) each of which has been defined by trenching over a length
    of 250 m with existing soil anomalies continuing in both directions
    along strike. 
    
--  At a 1.0 g/t Au cut-off the weighted average gold intercept in trenches
    completed to date at Montes de Oro is 16.0 metres grading 4.40 g/t Au. 
    
--  Recent trenching has focused on the Southern mineralized zone returning
    results including Trench MTR13-026 with 19.3 m grading 2.71 g/t Au. 



President and CEO, Greg Smith stated, "Additional work at Montes de Oro
continues to further delineate this exciting gold target. The trenching has now
defined two sub-parallel high grade gold mineralized zones each over
approximately 250 metres long and open in both directions. Additional trenching
is being initiated along the Northern zone targeting anomalous surface rock and
soil samples located 150 metres south of the currently defined southern extent."

The recent results continue to support the interpretation of at least two high
grade sub-parallel mineralized zones at Montes de Oro; the northern MTR13-009
trend and the southern MTR13-017 trend. The zones have an inferred northeast
orientation and appear to dip shallowly to the northwest. Each trend has now
been trenched over a distance of approximately 250 metres. 


The majority of the new results are from the southern tend which has now been
defined by three trenches; MTR-017, MTR-024, and MTR-026.


Work continues at Montes de Oro. Updated maps detailing the result of the
current exploration programs will be posted on the Company's web site at
www.calibremining.com. 


Quality assurance and quality control procedures include the systematic
insertion of blanks, standards and duplicates into the rock sample strings.
Samples are placed in sealed bags and shipped directly to Acme Labs in Managua,
Nicaragua for sample preparation and then to Acme Labs in Vancouver, Canada for
gold fire assay and ICP multi element analyses. The technical content in this
news release was read and approved by Gregory Smith, P.Geo, President and CEO of
the Company who is the Qualified Person as defined by NI 43-101.
