Summary of Mineral Reserve & Mineral Resource Estimates
Mineral Reserves are reported from pit designs and underground stope designs based on Indicated Mineral Resources. Mineral Resources are reported inclusive of those Mineral Resources that have been converted to Mineral Reserves.
Economic parameters such as mining costs, processing costs, metallurgic recoveries and geotechnical considerations have been applied to determine economic viability of the Mineral Reserves based on a gold price of US$1,250 per ounce ("/oz"). Mineral Reserves contained in stockpiles that meet the project-specific Mineral Reserve cutoff grades are also included for the Fekola and Otjikoto Mines and the Masbate Gold Project.
Mineral Resources amenable to open pit mining are constrained with conceptual pit shells defined by economic parameters and using a gold price of US$1,400/oz. Mineral Resources amenable to underground mining methods are reported above cutoff grades defined by site operating costs and using a gold price of US$1,400/oz. Mineral Resources contained in stockpiles that meet the project-specific cutoff grades are also included for the Fekola, Masbate and Otjikoto Mines. Gold grades are expressed in grams per tonne of gold ("g/t Au").
Except where stated otherwise, Mineral Reserve and Resource estimates for B2Gold's operating mines have been updated to account for mining depletion, using topographic surfaces as of December 31, 2018. These Mineral Reserve and Resource estimates are reported by project/mine on both a 100% project basis reflecting the total Mineral Resources and Mineral Reserves and the applicable project specific attributable basis reflecting B2Gold's ownership interest (details in notes below).

Notes: (Click to expand)
- Mineral Reserves have been classified using the CIM Standards (refer to the Company's AIF, dated March 20, 2019 – click here for additional information regarding these Mineral Reserves). 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.
- Fekola Mine: Mineral Reserves are reported on a 100% project and an 80% attributable basis; the remaining 20% interest is held by the State of Mali. The Mineral Reserves have an effective date of December 31, 2018. The Qualified Person for the estimate is Peter D. Montano, P.E.,who is B2Gold's Project Director. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/oz, metallurgical recovery of 94%, selling costs of $112.29/oz (including royalties), average mining cost of $2.49 per tonne ("/t") mined, average processing cost of $17.17/t processed, and site general costs of $4.39/t processed. Reserve model dilution and ore loss was applied through whole block averaging such that at a 0.8g/t cutoff there is a 1.4% increase in tonnes, a 2.1% reduction in grade, and a 0.7% reduction in ounces when compared to the Mineral Resource model. Mineral Reserves are reported above a cutoff grade of 0.8g/t Au.
- Masbate Gold Project: Mineral Reserves are reported on a 100% project basis. Pursuant to the ore sales and purchase agreement between Filminera and PGPRC, our wholly-owned subsidiary, PGPRC, has the right to purchase all ore from the Masbate Gold Project. B2Gold has a 40% interest in Filminera, which owns the majority of the Masbate Gold Project tenements. Please see heading "Material Properties – Masbate Gold Project" in pages 31-41 in the Company's AIF, dated March 20, 2019 (click here) for a further discussion of the foregoing. The Mineral Reserves have an effective date of December 31, 2018. The Qualified Person for the estimate is Kevin Pemberton, P.E., who is B2Gold's Chief Mine Planning Engineer. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/ounce, modeled metallurgical recovery (resulting in average LoM metallurgical recoveries by pit that range from 63% to 86%), selling costs of $54.11/oz and average base operating cost estimates of US$1.50–$1.80/t mined (mining), US$9.57/t processed (processing) and US$1.84–3.45/t processed (general and administrative). Dilution and ore loss were applied through block averaging such that at a cutoff of 0.49 g/t Au, there is a 7.7% increase in tonnes, a 6.6% reduction in grade and a 0.7% reduction in ounces when compared to the Mineral Resource model. Mineral Reserves are reported at cutoffs that range from 0.41–0.54 g/t Au.
- Otjikoto Mine: Mineral Reserves for Otjikoto and Wolfshag are reported on a 100% project and a 90% attributable basis; the remaining 10% interest is held by EVI Mining (Proprietary) Ltd., a Namibian empowerment company ("EVI"). The Mineral Reserves have an effective date of December 31, 2018. The Qualified Person for the estimate is Peter D. Montano, P.E., who is B2Gold's Project Director. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/oz, metallurgical recovery of 98%, selling costs of $51.44/oz including royalties and levies, average mining cost of $2.29/t mined, average processing cost of $12.99/t processed, and site general costs of $3.25/t processed. Reserve model dilution and ore loss was applied through whole block averaging such that at a 0.45 g/t cutoff there is a 2.3% decrease in tonnes, a 2.2% reduction in grade, and 4.4% reduction in ounces when compared to the Mineral Resource model. Mineral Reserves are reported above a cutoff grade of 0.45 g/t Au.
- La Libertad Mine: Mineral Reserves are reported on a 100% basis, and have an effective date of December 31, 2018. The Qualified Person for the estimate is Kevin Pemberton, P.E., who is B2Gold's Chief Mine Planning Engineer. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,250/ounce, metallurgical recoveries that range from 90% to 94%, and operating cost estimates of US$2.64/t mined (mining), US$14.80/t processed (processing) and US$3.50/t processed (general and administrative). 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 spent-ore. Mineral Reserves are reported at cutoffs that range from 0.64–0.74 g/t Au.
- El Limon Mine: Mineral Reserves are reported on a 100% basis. The Mineral Reserves have an effective date of December 31, 2018. The Qualified Person for the estimate is Kevin Pemberton, P.E., who is B2Gold's Chief Mine Planning Engineer. Mineral Reserves are based on underground long-hole stoping mining methods, gold price of US$1,250/ounce, metallurgical recovery of 93.5%, and operating cost estimates of US$53.90–US$82.39/t of ore (mining), US$29.45/t of ore processed (processing) and US$12.11/t processed (general and administrative). Dilution of 29–44% is applied to most zones in addition to 90% mine recovery for all zones. Mineral Reserves are reported at cutoffs that range from 2.80–3.27 g/t Au.
- Stockpiles: Mineral Reserves in stockpiled material are reported in the totals for the Otjikoto and Fekola Mines and the Masbate Gold Project, and were prepared by mine site personnel at each operation. Ore stockpile balances are derived from mining truck movements to individual stockpiles or detailed surveys, with grade estimated from routine grade control methods. Stockpile cutoffs vary by deposit, from 0.4–0.7 g/t Au.
