Based on exploration to date, B2Gold’s exploration team believes that there is significant potential to increase the Fekola mine life through further exploration drilling. The $15.4 million 2017 exploration drill program is ongoing at the Fekola property and regional area. The drilling is focused on testing the potential extension of the Fekola deposit to the north and the mineralized bedrock zones beneath the Anaconda saprolite resource on the Fekola Project area.

Fekola Mine Exploration:

Infill drilling continues on the resources outlined immediately below the Fekola reserve boundary, immediately to the north of the boundary and the near-surface portion of the Kiwi zone (to the north, now part of Fekola zone). The Company estimates that it could add up to 900,000 ounces of gold, consisting of 720,000 ounces from the existing indicated category and 180,000 from the existing inferred category to the Fekola mine plan with further infill drilling2. Exploration drilling at Fekola has included step out drilling to the north of the Fekola resource to begin testing the ultimate size potential of the Fekola deposit.

For recent results from these drill programs, click here for the Company’s news release "B2Gold Announces Positive Exploration Drill Results from the Fekola Property and Regional Targets in Mali, West Africa," dated November 9, 2017. Highlights from the news release include:

  • New drill results in the upper portion of the Fekola North Extension (formerly Kiwi zone) indicate it is part of the Fekola zone and has significantly extended mineralization to depth
     
  • New drill results above the deeper portion of the Fekola North Extension (formerly Fekola Deeps) have intersected wide zones of good-grade mineralization, closer to surface, and up to 600 metres north of the Fekola resource pit boundary
     
  • These results, combined with the deeper, mineralized intercepts in the upper portion of the Fekola North Extension area indicate that these zones are one contiguous mineralized zone that could dramatically increase the extent of Fekola mineralization. In addition, the mineralization remains open to the north beyond the new drill results
  • Drill results from the infill-drilling program, within the Fekola resource pit boundary, continue to convert inferred resources to indicated, confirming the potential addition of 900,000 ounces of gold

Fekola Regional Exploration:

On June 15, 2017, the Company announced the maiden Mineral Resource estimate for the Anaconda area of the Fekola Project (see below and click here for news release) and new exploration drill results from beneath the saprolite and for Anaconda (click here for news release). This initial Inferred Mineral Resource estimate is 21.59 million tonnes at 1.11 g/t gold for 767,000 ounces. The estimate is reported within a series of pit shells and above a 0.35 g/t gold cutoff grade.

The Anaconda Mineral Resource includes the Anaconda, Adder, Cobra, Cascabel, Mamba and Boomslang zones which occur as flat-lying to slightly dipping mineralized zones within saprolite and saprock. This resource occurs near surface and remains open along strike. At present, the combined Anaconda-Adder saprolite zone extends over 4.5 kilometres along strike and up to 500 metres wide at Anaconda and up to 200 metres wide at Adder. Within these zones, mineralized saprolite varies from several metres to over 40 metres thick, with an average true thickness of approximately 13.5 metres.

In 2017, over 56,000 metres of combined auger, aircore, RC and DD have been completed in this area in an effort to increase the saprolite-hosted Anaconda resource and to further explore for underlying zones of bedrock-hosted mineralization. 

Recent drilling has confirmed and extended the shallow saprolite inferred mineral resource and has discovered three, well-mineralized bedrock (sulphide) zones (the saprolite zone) beneath the Anaconda, Adder and Mamba zones, which indicate the potential for large Fekola-style mineralized zones.

Anaconda Resource Estimation Details:

The effective date of the Mineral Resource estimate is March 22, 2017. A total of 2,007 drill holes (107,048 metres of drilling) were used in the estimate. Of the total, there are 1,629 aircore drill holes (66,550 metres), 266 reverse circulation (“RC”) holes (31,778 metres) and 112 diamond drill core (“DD”) holes (8,720 metres). Much of the area is drilled at 40-metre by 40-metre spacing with local areas infilled to 20-metres by 20-metres and some areas drilled to 80-metres by 80-metres. A twin drilling program of 37 pairs of aircore to RC or aircore to DD were completed and results between aircore and DD and RC twins were comparable. Additionally, three 20-metre by 20-metre areas were infill drilled at 5-metre by 5-metre drill spacing with diamond drill core to test for grade continuity and to compare core results versus aircore and RC.

Ongoing Fekola Mine and Regional Exploration:

Drilling is ongoing to further test the Fekola North Extension zone, infill the Fekola resource, and further test the new bedrock mineralization beneath the Anaconda, Adder and Mamba saprolite resource. The Company is planning additional, aggressive exploration drilling programs on these targets in 2018.
