The Libertad Gold District covers an area of approximately 150 km2 in the central province of Nicaragua. La Libertad is owned 100% by B2Gold Corporation after Central Sun Mining Incorporated acquired on 26 March 2009
The La Libertad deposits are as low sulphidation gold systems consisting of several economic vein structures found in a belt of Oligocene age of tertiary volcanic rocks to Miocene. Andesite flows and pyroclastics hosting a series of generally east-west trending epithermal quartz veins, breccias and quartz stockwork. Several Little felsic intrusives similar tertiary to mafic along the northeast spread to southwest structural trends.
Exploration La Libertad mine In 2015
Drilling has been ongoing in Los Angeles for running resource from open pit mine, Jabali East and Mojon for underground resources and many new goals, some of which remain to be tested over the next year. The focus of the drilling to increase confidence in near mine resources and simultaneously test Large, new exploration vein structures.
Past Exploration In La Libertad mine
Eploration in 2012 in La Libertad mine area focuses on the Jabali infill program and drilling mine-related targets. The holes extend over an area of approximately 300 m along Slam and up to 150 meters depth.
The 2013 exploration campaign in La Libertad Mine Mine largely focused on drill testing of potential underground targets below the Mojon open pit, Jabali antenna and the Santa Maria mining.
In Mojon, a total of 13 holes were drilled on three underground areas beneath the current resource pit for 3,422 meters, and these will be pursued during 2014 definition programs.
At Jabali antenna was drilled, a similar program initiated for 3,104 meters with a total of 10 holes . The goal of this program was the downward finish extension of the main antenna where drilling historical and underground exploitation potential indicated for a Nice gold grades.
The highlights of this drilling program are holes JB13-418 with 103.8 g / t gold over 1.5 meters true width, JB13-418 with 10.67 g / t gold over 3.1 meters true width only 7 m deep and JB13- 410 with 5.72 g / t gold over 5.89 meters width.
The 2014 exploration program included on La Libertad Mine resource at Mojon drilling and exploration continues on a number of regional destinations.
The focus of the exploration drilling was mainly towards brownfields drilling and evaluation of regional targets for the search opencast feed to the mill
A total of 58 diamond drill holes were completed for 8250 meters in 4 destinations. These included the Mojon structure in which 32 holes were in an area below the pit design.
And geotechnical characteristics of the vein to test the extraction to investigate remaining material by underground methods. Other targets drill tested are the Los Angeles, Calvario and Mestiza vein structures
