La Libertad Mine is located in La Libertad-Santo Domingo Region in Central Nicaragua, approximately 110 km due east of the country's capital city, Managua. Click here for mine/project location map. 

B2Gold acquired its first gold development project, La Libertad Gold Project, through a merger with Central Sun Mining Inc. in March 2009. Previously a heap-leach mine, operations at La Libertad Mine were suspended in 2007 as a re-evaluation of the project indicated that gold recoveries could be greatly improved using a conventional milling operation. Following construction of a SAG and ball mill grinding circuit, as well as carbon-in-pulp recovery tanks and a tailings impoundment, La Libertad Mine was reopened by B2Gold and achieved commercial production on February 1, 2010, on schedule. Click here for La Libertad Mine overview
