La Libertad mine - Nicaragua
Open Pit and Underground, 100% B2Gold Ownership
FY 2016: Update
For the full-year 2016, La Libertad mine produced 132,431 ounces of gold, near the high end of its production guidance range (of 125,000 to 135,000 ounces) and 11% (or 12,956 ounces) higher than 2015. Better grade and higher recoveries contributed to the successful production year.
On May 5, 2016, B2Gold received the 2015 Award for Social Responsibility in Nicaragua for its work on the Jabalí Antena settlement project. The award recognizes the Company’s commitment to social development projects that benefit the local communities in which it operates.
Q4 2016: Update
La Libertad’s fourth quarter 2016 production was 35,165 ounces of gold, consistent with the fourth quarter of 2015.
La Libertad's third quarter 2016 cash operating costs(1) were $637 per ounce of gold, $64 per ounce (or 9%) below budget and $22 per ounce (or 3%) below the prior-year quarter.
La Libertad's third quarter 2016 all-in sustaining costs(1) were $788 per ounce of gold, below both budget of $908 per ounce and $812 per ounce in the prior-year quarter.
La Libertad's year-to-date 2016 cash operating costs were $658 per ounce of gold, $41 per ounce (or 6%) below budget and $106 per ounce (or 14%) below the same period in 2015.
La Libertad's year-to-date 2016 all-in sustaining costs were $913 per ounce of gold, below both budget of $1,153 per ounce and $1,034 per ounce in the same period in 2015.
During the third quarter of 2016, La Libertad’s mine schedule was adjusted to mine additional high-grade ore from the Jabali Central pit to offset permitting delays at the Jabali Antenna pit. The Jabali Antenna pit is now planned for production in the third quarter of 2017, pending completion of permitting and relocation activities. However, as in 2016, La Libertad retains some flexibility in sourcing its ore while the Jabali Antena permitting and relocation activities are being completed.
In 2017, La Libertad is budgeted to process 2.3 million tonnes of ore at an average grade of 1.73 g/t with gold recoveries averaging 94%. Mill feed is expected to consist mainly of high grade ore from Jabali Central pit (37%), Mojon underground (8%), and Jabali Antenna pit (5%), which will be blended with lower grade spent ore (50%). Jabali West underground mine development is expected to commence in 2017, with production expected to commence in 2018.
La Libertad is expected to produce between 110,000 and 120,000 ounces of gold in 2017 at cash operating costs of between $625 and $665 per ounce and all-in sustaining costs of between $785 and $815 per ounce.

La Libertad mine is located approximately 110 km due east of Managua, the capital city of Nicaragua and 32 km northeast of Juigalpa. The property is situated near the town of La Libertad in La Libertad-Santo Domingo Region of the Department of Chontales in Central Nicaragua. Access to the La Libertad property is 201 km by paved road from Managua to Juigalpa, the capital city of the Department of Chontales. From Juigalpa, a newly paved road (paver stones) leads northeast for 30 km to the town of La Libertad. Access to the mine site is along a five km, secondary unsurfaced road that originates at the entrance to the town of La Libertad. In total, La Libertad mine is 236 km from Managua.
B2Gold, indirectly through its subsidiary, Desarrollo Minero de Nicaragua S.A. (“Desminic”), hold a 100% interest in one exploitation concession for La Libertad covering 10,950 hectares, granted on September 6, 1994 for the term of 40 years pursuant to Ministerial Decree No. 032-RN-MC/94. The principal obligations under the Ministerial Accord include the annual payment of surface taxes, and a net 3.0% royalty on gross production revenues (ad valorem tax) payable to the government of Nicaragua. In addition, B2Gold holds an interest in two exploration concessions consisting of Buenaventura (100%) and Cerro Quiroz (80%) which cover a total of 4,600 hectares and are contiguous to the La Libertad exploitation concession.
La Libertad mine is also subject to a royalty interest granted to Inversiones Mineras S.A. (“IMISA”), a holding company formed to represent unionized mine workers in Nicaragua, equal to 2.0% of the value of total production of gold and silver from La Libertad exploitation concession. In Nicaragua, the government is entitled to an ad-valorem tax over the substances extracted from a mineral concession. The amount of ad-valorem tax is 3% for minerals. Under Nicaraguan law, the ad-valorem tax paid is considered a deductible expense for purposes of computing corporate income tax. However, when this law was enacted, it included a grandfathering rule which allowed concessions granted prior to this law to continue operating under its existing regime. Under the mining law applicable at the time, the amount paid as ad-valorem tax is applied as a direct credit against corporate income tax. The total royalty payable on La Libertad mine production is 5.0%. In addition, under Nicaraguan law, artisanal miners have the right to exploit secondary veins up to a total surface area that may not exceed 1% of the total area granted under a concession. Artisanal mining activities continue on the concession.
