VANCOUVER, British Columbia, June 15, 2017 (GLOBE NEWSWIRE) -- B2Gold Corp. (TSX:BTO) (NYSE MKT:BTG) (NSX:B2G) ("B2Gold" or the "Company") is pleased to announce the maiden Mineral Resource estimate for the Anaconda area of the Fekola Project located in southwestern Mali and new exploration drill results from beneath the saprolite and for Anaconda. 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. This saprolite-hosted gold mineralization remains open and B2Gold's Exploration group is continuing to explore the edges of the known zones, and test for additional saprolite hosted mineralized zones and Fekola-style mineralization within the bedrock.

Highlights
  • 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
  • A conceptual engineering study is underway for Anaconda to determine the economics of mining and processing the soft saprolite material. Initial results indicate the potential for a standalone operation
  • The 2016 exploration program identified several bedrock structures, below the saprolite, that may have weathered to create the extensive zones of saprolite-hosted gold mineralization. These mineralized bedrock structures have the potential to host new additional Fekola-style zones. Further drilling is ongoing to test these zones
  • Recent significant drill results at the Kiwi zone to the north of the projected Fekola pit, containing up to 2.14 g/t over 25 metres in FSER_173

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.
