La Libertad Mine – Nicaragua

La Libertad's exploration budget for 2017 is approximately $6.7 million for a total of 15,000 metres of planned diamond drilling. The program is comprised of 7,000 metres of brownfields drilling and 8,000 metres of drilling planned on several regional targets.

Mineral Reserve and Mineral Resource Estimates:
 

Mineral Resource estimates for La Libertad mine are reported from B2Gold’s mineral resource models with model dates ranging from February 2016 to January 2017; the December 31, 2016 topographic surface is applied to the models making this date the overall effective date of the estimates. No Measured Mineral Resources were estimated.

  1. Mineral Resources have been classified using the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Mineral Resources are reported inclusive of those Mineral Resources that have been modified to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability
  2. All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content
  3. Mineral Resources are reported on a 100% attributable basis
  4. The Qualified Person for the estimate is Brian Scott, P. Geo., who is our Vice President, Geology and Technical Services
  5. Mineral Resource estimates assume an open pit mining method, gold price of US$1,400/oz, metallurgical recoveries that range from 90% to 94%, and operating cost estimates of US$3.88/t mined (mining), US$13.31/t processed (processing) and US$4.13/t processed (general and administrative)
  6. Mineral Resources are reported at cutoffs that range from 0.61-2.85 g/t Au

Mineral Reserve estimates for the La Libertad mine are reported from B2Gold’s mineral resource models that have an effective date of December 31, 2016, and have been modified from the Indicated Mineral Resources. No Proven Mineral Reserves have been reported.

  3. Mineral Reserves are reported on a 100% attributable basis
  4. The Qualified Person for the estimate is Kevin Pemberton, P.E., who is our Chief Mine Planning Engineer
  5. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/oz, metallurgical recoveries that range from 90% to 94%, and operating cost estimates of US$3.88/t mined (mining), US$13.31/t processed (processing) and US$4.13/t processed (general and administrative)
  6. Dilution and ore loss was applied to the Jabali material through block averaging such that at a cutoff of 0.75-0.76 g/t Au, there is a 15% increase in tonnes, a 26% reduction in grade and 14% reduction in ounces when compared to the Mineral Resource model. No dilution is applied to the spent-ore
  7. Mineral Reserves are reported at cutoffs that range from 0.70-0.76 g/t Au
