News Release

B2Gold and AngloGold Ashanti to Amend Ownership and Management of the

Gramalote Project, Colombia

Vancouver, September 16, 2019 – B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G)

(“B2Gold” or the “Company”) is pleased to announce that the Company and AngloGold Ashanti Limited

(“AngloGold”) have agreed in principle to terms relating to the parties’ respective ownership percentages

and future management of the j oint venture on the Gramalote gold project in Colo mbia. The companies

have agreed that B2Gold will sole fund the next $ 13.9 million of expenditures on the Gramalote Project

(the “Sole Fund Amount”), following which B2Gold will hold a 50% ownership interest in the joint venture

(B2Gold currently holds a 48.3% interest) . Under the amended terms, AngloGold and B2Gold will each

hold a 50% interest and B2Gold will start an immediate transition to become manager of the Gramalote

joint ventur e by the end of 2019 , conditional upon the parties entering into an amended and restated

shareholders agreement . The parties will continue to have equal representation on the joint venture

management committee. Following the expenditure of the Sole Fund Amount, each joint venture partner

will fund its share of expenditures pro rata.

B2Gold and AngloGold have also agreed on a budget for the feasibility study on the Gramalote Project up

to $40 million for the remainder of 2019 and through the end of 2020. This budget will fund 42,500 metres

of infill drilling and 7,645 metres of geotechnical drill ing for site infrastructure. The Company currently

expects to complete all drilling by the end of May 2020. In addition, the budget will fund feasibility work

including an updated mineral resource, detailed mine planning, additional environmental studies,

metallurgical test work, engineering and detailed economic analysis.

The Company expects that th e Gramalote joint venture will continue to advance resettlement programs,

establish coexistence programs for small miners, work on health , safety and environmental projects and

will continue to work with government and local communities on social programs. B2Gold, as manager,

plans to continue the feasibility work int o 2020 with the goal of completing a final feasibility study by

December 31, 2020. Due to the extensive testing programs that have been completed and the high level of

engineering performed in 2017 for an internal pre-feasibility study, the engineering work remaining to get

to final feasibility is not extensive. The main work program for feasibility is infill drilling to confirm and

upgrade the Inferred Mineral Resources to Indicated status.

The Gramalote Project is located 230 kilometres (“km”) northwest of Bogota and 80 km northeast of

Medellin in central Colombia. Based on the recent remodeling of the G ramalote geologic resource, the

Company believes t hat the Gramalote Project has the potential, subject to completion of infill drilling

scheduled to commence in November 2019 and a final feasibility study expected by the end of 202 0, to

become a large low -cost open pit gold mine. The Gramalote Project has several key infrastructure

advantages, including:

2

• Reliable water supply – high rainfall region

• Adjacent to a national highway, which connects to a major river and seaports

• Proximity to the national electricity grid with ample low -cost power and stable record of hydroelectric

power

• Technically capable workforce within Colombia

The Environmental Impact Study and Project Implementation Plans for the Gramalote Project have been

fully approved by the National Authority of Environmental Licenses of Colombia . Due to the desired

modifications to the processing plant and infrastructure locations, a Modified Environment Impact Study

and a Modified Project Implementation plan were submitted and are currently in the final approval process.

If the final economics of the feasibility study are positive and the joint venture makes the decision to develop

Gramalote as an open -pit gold mine, B2Gold would utilize its proven internal mine construction team to

build the mine and mill facilities.

Tom Garagan, Senior Vice President of Exploration for B2Gold, has acted as the qualified person as defined

in National Instrument 43 -101 for this disclosure and supervised the preparation of the technical

information in this news release.

Cautionary Note to United States Investors

The Company has prepared its public disclosures in accordance with Canadian securities laws, which differ in certain

respects from U.S. securities laws. In particular, this news release may refer to “mineral resources”, “measured

mineral resources”, “indic ated mineral resources” or “inferred mineral resources”. While these categories of

mineralization are recognized and required by Canadian securities laws, they are not recognized by the SEC and are

not normally permitted to be disclosed in SEC filings by U .S. companies. U.S. investors are cautioned not to assume

that any part of a “mineral resource”, “measured mineral resource”, “indicated mineral resource” or “inferred

mineral resource” will ever be converted into a “reserve.” In addition, “reserves” repor ted by the Company under

Canadian standards may not qualify as reserves under SEC standards. Under SEC standards, mineralization may not

be classified as a “reserve” unless the mineralization can be economically and legally extracted or produced at the

time the “reserve” determination is made. Accordingly, information contained or referenced in this news release

containing descriptions of the Company’s mineral deposits may not be compatible to similar information made public

by U.S. companies subject to the reporting and disclosure requirements of U.S. federal securities laws, rules and

regulations. “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 will ever be upgraded to a higher category. Historical results or feasibility models presented herein are not

guarantees or expectations of future performance.
