B2Gold Corp. Announces Positive Results from the Preliminary Economic Assessment for the Gramalote Project in Colombia

VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 03/13/14 -- B2Gold Corp. (TSX:BTO)(NYSE MKT:BTG)(NAMIBIAN:B2G) ("B2Gold" or the "Company") is pleased to announce positive results from the Preliminary Economic Assessment ("PEA") for the Gramalote gold project in Colombia. The Gramalote property is a 51% AngloGold Ashanti Ltd. ("AngloGold Ashanti") and 49% B2Gold joint venture with AngloGold Ashanti as the project manager. Gramalote is located 230 kilometers ("km") northwest of Bogota and 80 km northeast of Medellin in central Colombia.

Highlights of the Gramalote Preliminary Economic Assessment on a 100% basis


--  Open pit gold mine with an initial life of mine ("LOM") of 14 years
    based on Measured, Indicated and Inferred Mineral Resources.  
--  Average annual gold production LOM of 317,500 ounces at US$664 direct
    cash cost per ounce. 
--  Average annual gold production of 373,300 ounces per year for the first
    5 years of production. 
--  LOM gold production of 4.445 million ounces.

--  Project payback of 4.8 years.

Project Size Trade-off study

A trade-off study was completed to determine the optimum throughput rate for the Gramalote project. Throughput rates between 10 million and 24 million tonnes per year were evaluated at gold prices of $1,100 per ounce, $1,300 per ounce and $1,500 per ounce utilizing Inferred Mineral Resources. The results of this study indicate that 16.0 million tonnes per year provides the best project economics and allows for the use of conventional dual pinion drive grinding mills.

The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA based on these Mineral Resources will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Mineral Resources

The Company is pleased to announce AngloGold Ashanti has completed a new Joint Ore Reserves Committee and National Instrument 43-101 compliant Mineral Resource estimate for Gramalote Central Zone, Monjas West and Trinidad. The new mineral resource estimate was utilized in the preparation of the PEA.

Total Measured and Indicated Mineral Resources at Gramalote Central and Monjas West at a 0.15 gram per tonne ("g/t") gold cut-off, within a US$1,600 per ounce gold optimized Whittle pit consists of 132.7 million tonnes grading 0.63 g/t gold for a total of 2.69 million troy ounces of gold. The Gramalote Central, Monjas West and Trinidad Inferred Mineral Resource is 239.7 million tonnes grading 0.44 g/t gold for a total of 3.36 million troy ounces of gold using similar parameters as the Measured and Indicated Mineral Resource.

The following table outlines the updated Gramalote Mineral Resource estimate ona 100% basis using a 0.15 g/t gold cut-off grade and within a US$1,600 per ounce gold optimized Whittle pit:

1.  Differences in tonnage, ounces and grades due to rounding 
2.  Mineral resources that are not Mineral Reserves do not have a
    demonstrated economic viability. Due to the uncertainty which may be
    attached to Inferred Mineral Resources, it cannot be assumed that all or
    any part of an Inferred Mineral Resource will be upgraded to an
    Indicated or Measured Mineral Resource as a result of continued
    exploration.

B2Gold published in 2012 a National Instrument 43-101 compliant Measured and Indicated Mineral Resource at Gramalote Central of 97.1 million tonnes grading 0.81 g/t gold for a total of 2.5 million troy ounces of gold at a 0.25 g/t gold cut-off and within a US$1,600 per ounce gold optimized Whittle pit. The Gramalote Central and Trinidad Inferred Mineral Resource was 95.7 million tonnes grading 0.44 g/t gold for a total of 1.36 million troy ounces of gold using similar parameters as the Measured and Indicated Mineral Resource (see press release dated April 24, 2012).

The new Gramalote Central Mineral Resource estimate is supported by 63,902 metres of diamond drilling in 176 drill holes completed in 2007 to 2013 and 441 metres of sampling from an underground tunnel. The Monjas West Mineral Resource is supported by 18,094 metres of diamond drilling in 46 drill holes and a total of 10,572 metres of diamond drilling in 30 holes drilled was used in the Trinidad Mineral Resource estimation. Average drill hole spacing used in the Mineral Resource was 25 metres x 25 metres for Measured, 50 metres x 50 metres for Indicated and 100 metres x 100 metres for Inferred.

The Gramalote resource was prepared by AngloGold Ashanti and AMEC carried out an independent audit of the low grade zone at Gramalote Central in June 2013. AngloGold Ashanti monitored the quality assurance and quality control ("QA/QC") program of the data they collected in 2010 to 2013.

The Qualified Person (under National Instrument 43-101) for AngloGold Ashanti's resource estimate is Vaughan Chamberlain, FAusIMM, Senior Vice President, Geology and Metallurgy, AngloGold Ashanti Ltd. The drilling program at the Gramalote property is reviewed and the results approved by Tom Garagan, B2Gold's Qualified Person under National Instrument 43-101. The Gramalote drill program utilizes extensive QA/QC (quality assurance and quality control) protocols for assaying and core sample handling that consist of the systematic insertion of blanks, standards and duplicates as well as using a secondary laboratory for regular check assaying. Core samples are cut with a diamond saw with one-half of the core placed in sealed bags and shipped directly to ALS Chemex Labs in Bogota, Colombia for sample preparation with the pulps subsequently sent to ALS Chemex Labs in Lima, Peru for gold fire assay and ICP analyses.

Summary of Base Case Results

The PEA is subject to a number of assumptions, including among others, that an environmental impact assessment will be completed within the required timeline, all required permits will be obtained in a timely manner, the Gramalote project will have the support of the local government and community, the regulatory environment will remain consistent and no material increase will have occurred to the estimated costs. A full list of the relevant assumptions will be set out in the PEA.

Project Sensitivities

Gramalote is a large, low grade, low cost project and is therefore very sensitive to the gold price. A table reflecting these sensitivities is shown below.

Next Steps

At current gold price levels, the Gramalote Project economics are positive but at this time do not move the project to the top of the Company's priority list for continued development towards a Feasibility Study. The Gramalote project joint venture partners have agreed on a work program for 2014 that advances the Environmental Impact Study so it can be formally submitted to the Colombian regulators by the second quarter of 2014, which is key to advancing the Gramalote project permitting process. Focus will also be given on addressing other project risk issues such as infill drilling of Inferred Mineral Resources, social programs, environmental monitoring and government relations. Gramalote owns two diamond drills and will utilize those two machines to target 8,000 to 10,000 meters of infill drilling in 2014. At this time, a final budget for 2014 has not been agreed on but this should be finalized within the next month.

The project will be reviewed again in the 4th quarter of 2014 to determine if moving to a Feasibility Study is warranted at that time.

Cautionary Note to U.S. Readers Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

Information concerning the properties and operations discussed in this news release has been prepared in accordance with Canadian standards under applicable Canadian securities laws, and may not be comparable to similar information for United States companies. The terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" used in this news release are Canadian mining terms as defined in accordance with NI 43-101 under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on December 11, 2005. While the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are recognized and required by Canadian regulations, they are not defined terms under standards of the United States Securities and Exchange Commission. Under United States 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 calculation is made. As such, certain information contained in this news release concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission. An "Inferred Mineral Resource" has a great amount of uncertainty as to its existence and as to its economic and legal feasibility. It cannot be assumed that all or any part of an "Inferred Mineral Resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves. Readers are also cautioned not to assume that all or any part of an "Inferred Mineral Resource" exists, or is economically or legally mineable. In addition, the definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" under CIM standards differ in certain respects from the standards of the United States Securities and Exchange Commission.
