B2Gold Corp: Maiden Saprolite Mineral Resource Estimate - Fekola Project, Mali

Vancouver, British Columbia--(Newsfile Corp. - June 15, 2017) - 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.


  • 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.

Notes to accompany Mineral Resource Table:

  1. Mineral Resources have an effective date of March 22, 2017 and are reported on a 100% ownership basis

  2. The Qualified Person for the estimate is Tom Garagan, P.Geo., B2Gold's Senior Vice President of Exploration

  3. Resources are reported within a conceptual Lerchs-Grossmann pit shell assuming the following parameters: gold price of US$1400/oz., gold recovery of 95%, mining cost of US$1.75/t, processing cost of US$8.10/t mill feed, G&A cost of US$2.75/t mill feed, and 35 degree pit slope angles

  4. Inferred Mineral Resources are reported at a cutoff grade of 0.35 g/t gold

  5. Mineral Resources have been classified using the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability

  6. Due to the uncertainty that may be attached to Inferred Mineral Resources, it cannot be assumed that all or any part of an Inferred Mineral Resource will be converted to Indicated or Measured Mineral Resources as a result of continued exploration

  7. Figures are rounded and may not sum

Regolith model, including bases of laterite, saprolite and saprock, was built in 3D from detailed drill hole logging of weathering intensity and lithology. Mineralization zones at nominal grade thresholds of 0.2 g/t gold and 0.6 g/t gold were built in 3D and were used to control the gold grade estimates.

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. Composite sharing across the mineralization zone and laterite contacts was not warranted.

A total of 1,641 bulk density measurements using the water-displacement method on dried laterite, saprolite and saprock samples were completed at the project site. The average densities used for tonnage and contained metal estimates are 2.07 t/m3 for laterite, 1.44 t/m3 for saprolite and 1.90 t/m3 for saprock.

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.

The block model estimates were checked against input composite data visually on screen and on paper plots. Additional checks completed include swath plots, and comparison of original and declustered composites versus kriged block model results by domain.

West African Exploration Update

In April 2017, the Company's Board of Directors approved an additional $7 million worth of proposed exploration expenditures, which increases the West African exploration budget to approximately $27 million for 2017. These additional funds will allow for the advancement of prospects that are currently over and above the focus of ongoing exploration programs.

Mali Exploration Results

Drilling is currently underway at the Kiwi zone, which is located directly to the north of, and along strike of, the current Fekola Deposit pit boundary. The Kiwi zone sits above the Fekola Deeps zone, and is open to the north, where previous deeper drilling had intersected wide zones of good-grade mineralization (see below). Prior to the Kiwi drilling, the Company assumed the Fekola Deeps zone could have the potential to be mined from underground in later years. If the Kiwi zone continues to intercept gold mineralization at depth, then the potential would be to extend the Fekola pit to the north and mine a portion of Kiwi and Fekola Deeps by open pit. Recent highlights from Kiwi zone drilling include:

Burkina Faso

Drilling is ongoing at the Toega prospect in Burkina Faso. Three drill rigs are currently on site with the objectives of expanding known mineralization at Toega and stepping out to test for additional mineralization at other targets in the region. Highlights from recent drilling include NKDD030, which intersected 22.40 metres at 5.20 g/t gold, from 242.00 metres. A maiden Mineral Resource estimate for Toega is scheduled for completion in the third quarter of 2017.

Quality assurance and quality control (QA/QC) measures on assaying and sample preparation include regular insertion of certified reference, field duplicate and blank sample materials prior to submission of samples to the laboratory. QA/QC sample insertion rates are 1:35 for standards and blanks. QA/QC data are reviewed on a continuous basis and before data are imported into the database. Comprehensive QA/QC reports are generated and reviewed monthly by senior staff. Data imported into the project database are subject to validation, which includes checks on surveys, collar coordinates, lithology data, and assay data. Sample security measures include moving all samples from the drill site to the Toega and Fekola camp yards at the end of each drill shift, and tracking of sample shipments using industry-standard procedures.

Tom Garagan, P.Geo., B2Gold's Senior Vice President of Exploration, a qualified person under National Instrument 43-101, has approved the scientific and technical information contained in this news release. As Senior Vice President of Exploration, Tom Garagan supervises all work.

The disclosure in this news release regarding mineral properties was prepared in accordance with Canadian National Instrument 43-101 ("NI 43-101"), which differs significantly from the mineral reserve disclosure requirements of the SEC set out in Industry Guide 7. In particular, NI 43-101 permits companies to use the term "resources", which are not "reserves". Under U.S. standards, companies are not normally permitted to disclose mineralization that does not constitute "reserves" in filings with the SEC. Accordingly, while Mineral Resources are recognized and required to be disclosed by NI 43-101, the SEC's disclosure standards normally do not permit companies to disclose Mineral Resources in their filings with the SEC. In addition, the definitions of "reserves" and related terms under NI 43-101 and the SEC's Industry Guide 7 differ significantly. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Investors are specifically cautioned not to assume that any part or all of "Measured Mineral Resources", "Indicated Mineral Resources" or "Inferred Mineral Resources" will ever be converted into a higher category, including SEC defined mineral reserves. Investors should also understand that "Inferred Mineral Resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "Inferred Mineral Resource" exists or is economically or legally mineable. Further, while NI 43-101 permits companies to disclose economic projections contained in preliminary economic assessments and pre-feasibility studies, which are not based on "reserves", U.S. companies are not normally permitted to disclose economic projections for a mineral property in their SEC filings prior to the establishment of "reserves". For the above reasons, information contained in this news release regarding mineral properties is not comparable to similar information made public by companies that report in accordance with U.S. standards.
