Maiden mineral resource for 767K oz

B2Gold estimated the maiden Mineral Resource for the Anaconda area of the Fekola Project located in south western 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.

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.

Gold assays were capped prior to compositing to two metres, with capping at 2.5 g/t for the 0.2 g/t shell, 16 g/t for the 0.6 g/t shell and 2.0 g/t for laterite. Capping levels were based on statistics and spatial consideration of the high-grade assays. Block model gold grades were estimated into 20-metre by 20-metre by 2-metre blocks using Ordinary Kriging.

Inferred Mineral Resources are supported by a nominal drill hole spacing of 80-metres by 80-metres; however, 90% of the reported resource has been drilled to the tighter 40-metre by 40-metre drill spacing.
