VANCOUVER, Jan. 16, 2020 /CNW/ - B2Gold Corp. (TSX:BTO, NYSE AMERICAN: BTG, NSX:B2G) ("B2Gold"or the "Company") is pleased to announce an updated Fekola Mineral Resource estimate including a substantial increase in Indicated Mineral Resources at the Fekola Mine following a successful infill drill program in 2019.

Highlights:
•Updated Fekola Indicated Mineral Resource estimate as at December 31, 2019 of 110,600,000 tonnes at 1.70 grams per tonne ("g/t") gold for a total of 6,052,000 ounces of gold constrained within a $1,500 per ounce gold pit shell above a cut-off grade of 0.5 g/t gold


•The updated Fekola Mineral Resource estimate as at December 31, 2019 represents a 2,675,000 ounce increase (+79 %) in Indicated Mineral Resources when compared to the estimate included in the June 2015 Fekola Optimized Feasibility Study (after adjusting for cumulative Fekola Mine gold production to date of 1,006,000 gold ounces)


•When compared to the December 31, 2018 Fekola Indicated Mineral Resource estimate the updated Indicated Mineral Resource estimate has increased by 1,290,000 ounces of gold (15.4%) (after adjusting for the 455,810 ounces of gold produced in 2019)


•As recently reported, the Fekola Mine produced its first million ounces of gold in late December 2019 after 2.5 years of production


Updated Fekola Mineral Resource Estimate:

In 2019, B2Gold completed more than 25,000 metres of reverse circulation and diamond drilling at Fekola with the primary goal of converting existing resources in the Inferred Mineral Resource category to the Indicated Mineral Resource category. This infill drilling program was successful and the updated Fekola Mineral Resource estimate is based on the cumulative 240,000 metres of exploration drilling to date in 1,124 drill holes (including 120,000 metres in 501 holes drilled by B2Gold since June 2014).

The updated Fekola Indicated Mineral Resource estimate as at December 31, 2019 will provide the basis for an updated design pit and new Fekola Probable Mineral Reserve estimate, which is expected to be completed during the first quarter of 2020. The current Fekola Mineral Reserve design pit is located well within the updated Fekola Mineral Resource pit.

Fekola Mineral Resource Comparison (to June 2015 Fekola Optimized Feasibility Study)

Comparing the updated 2019 Fekola Mineral Resource estimate to a sensitivity case presented in the June 2015 Fekola Optimized Feasibility Study and adjusted for gold produced to date, there is an increase of 2,675,000 ounces of gold (+79 %) in the indicated category and a 541,000 ounce increase (+107% ) in the inferred category. A Mineral Resource sensitivity case in the June 2015 Fekola Optimized Feasibility Study reported 4,383,000 ounces (67,293,000 tonnes at 2.03g/t gold, above a cutoff of 0.5g/t gold) in the indicated cateogry and 507,000 ounces (9,990,000 tonnes at 1.58 g/t gold, above a cutoff of 0.5g/t gold) in the inferred category. The Fekola Mine has produced 1,006,000 ounces of gold to date between the commencement of operations in 2017 and December 31, 2019. The June 2015 Fekola Optimized Feasibility Study Indicated resource was adjusted by these Fekola cumulative production numbers and then compared to the updated Fekola Mineral Resource estimate as at December 31, 2019. Both the updated Fekola Mineral Resource estimate and the June 2015 Fekola Optimized Feasibility Study senstivity case reported Mineral Resources within $1500 pit shells and above a cut-off of 0.5 g/t gold.

2020 Fekola and Anaconda Regional Exploration Plans

The Fekola deposit remains open down plunge to the north. Exploration in 2020 will continue to test for extensions to the deposit to the north and south both at depth and near surface as well as testing for additional mineralized zones to the east and west of the Fekola deposit.

Exploration in 2019 on the Anaconda Area (located 20 kilometres north of Fekola) included completion of over 45,000 metres of combined aircore, diamond and reverse circulation drilling where the Company previously announced an initial Inferred Mineral Resource estimate of 767,000 ounces of gold at 1.1 g/t in near-surface mineralization over 4.5 kilometres and up to 500 metres wide.

In 2019, Anaconda Area drilling focused on increasing the known saprolite resources at the Adder and Mamba zones and further testing the underlying sulphide mineralization in the Mamba zone. At Adder, drilling has extended the strike extent of mineralization up to 1 kilometre north of the known resource area and remains open to the north. At Mamba, recent drilling has extended the high-grade mineralized saprolite zone by approximately 600 metres, resulting in more than 1 kilometre of known strike length, and has led to the discovery of a continuous, good grade, bedrock sulphide zone down plunge of the Mamba zone's saprolite mineralization. Early indications are that the Mamba zone discovery has the potential to become a significant new gold deposit for B2Gold near the Fekola Mine. This Fekola-style, south-plunging body of sulphide mineralization remains open down plunge and will be the subject of extensive drilling in 2020.

Exploration in 2020 will also focus on expanding the saprolite resources within the overall Anaconda Area, including at the Adder and Mamba Zones. The total 2020 exploration budget for both the Fekola deposit and the Anaconda Area is approximately $18 million.

Resource Model Methodology

The updated Fekola Mineral Resource model was prepared in-house by B2Gold personnel. Three dimensional mineralization domain models, which are used to control gold grade estimates, are supported by modeled stratigraphy and shear zone structures which are derived from detailed logging of oriented drill core. Tight asymmetric folds and shear zones are the primary controls on mineralization.

Assays were capped separately for each of three mineralization domains at 1.5 g/t, 5 g/t and 30 g/t gold respectively. Gold assays were capped prior to compositing to 2 metres. Grades were estimated into the block model using Ordinary Kriging (OK) with searches dynamically controlled along mineralization zone directions.

Approximately 24,250 bulk density measurements using the water-displacement method on air-dried core samples were completed at the project site. Variability of density for unweathered rock is low, therefore, densities were assigned based on averages by mineralization domain, waste and regolith.

Nominal drill hole spacing for Indicated Mineral Resources is 55 by 55 metres and for Inferred Mineral Resources it is 100 by 100 metres.

QA/QC on Sample Collection and Assaying

The primary laboratories for Fekola are SGS Laboratories in Bamako, Mali and Bureau Veritas Laboratories in Abidjan, Cote d'Ivoire. Periodically, exploration samples will be analyzed at the Fekola mine lab. At each lab, samples are prepared and analyzed using 50 g fire assay with atomic absorption finish and/or gravimetric finish. Umpire assays are used to monitor lab performance monthly.

Quality assurance and quality control ("QA/QC") procedures include the systematic insertion of blanks, standards and duplicates into the core, reverse circulation and aircore drilling sample strings. The results of the control samples are evaluated on a regular basis with batches re-analyzed and/or resubmitted as needed. All results stated in this news release have passed B2Gold's QA/QC protocols.
