B2Gold Corp. Announces Positive Results from the Updated Preliminary Economic Assessment...

VANCOUVERJan. 21, 2020 /CNW/ - B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) ("B2Gold" or the "Company") is pleased to announce positive results from the Updated  Preliminary Economic Assessment ("PEA") for the Gramalote Ridge deposit ("Gramalote Ridge") at the Gramalote gold project in Colombia (the "Gramalote Project"), a joint venture between B2Gold and AngloGold Ashanti Ltd ("AGA"). B2Gold assumed the role of manager of the Gramalote joint venture on January 1, 2020. All dollar figures are in United States dollars unless otherwise stated.


  • Assuming an effective date of January 1, 2020, and a gold price of $1,350 per ounce, Gramalote Ridge project economic highlights from the PEA (100% basis) include:
    • Open-pit gold mine with an initial life of mine ("LoM") of 13.6 years based on current Indicated and Inferred Mineral Resources (for Gramalote Ridge only)
    • LoM gold production of 3.85 million ounces
    • Average annual gold production of 416,600 ounces per year for the first five full years of production
    • Average annual gold production LoM of 283,990 ounces per year at cash operating costs of $544 per ounce of gold
    • Average LoM all-in sustaining costs ("AISC") of $648 per ounce of gold, and average LoM all-in costs (including pre-production capital costs) of $882 per ounce of gold
    • Annual processing rate of 11.0 million tonnes per annum ("Mtpa")
    • Average LoM gold recovery of 94.3% from conventional milling, flotation and cyanide leach of the flotation concentrate
    • Estimated pre-production capital cost of $901 million (includes approximately $160 million for mining equipment)
    • LoM pre-tax net cash flow of $1,827 million, and after-tax net cash flow of $1,283 million
    • Assuming a discount rate of 5%, net present value ("NPV") pre-tax of $1,027 million and NPV after-tax of $671 million, generating an after-tax internal rate of return ("IRR") of 18.1% at the project construction decision date (estimated to be January 1, 2021), with a project payback (including construction capital) of 3.6 years
    • Assuming a gold price of $1,500 per ounce and a discount rate of 5%, NPV pre-tax increases to $1,394 million and NPV after-tax increases to $928 million, generating an after-tax IRR of 21.9% at the project construction decision date (estimated to be January 1, 2021) and reducing the project payback (including construction capital) to 3.2 years
  • Continue ongoing feasibility work to optimize the PEA results and a final feasibility study expected to be completed by December 31, 2020
  • Amended and restated shareholders agreement signed by B2Gold and AGA on December 23, 2019, under which B2Gold agreed to sole fund the next $13.9 million of expenditures on the Gramalote Project, following which B2Gold and AGA will each hold a 50% ownership interest in the joint venture (currently 48.3% B2Gold and 51.7% AGA)
  • Exploration drilling is ongoing at the Trinidad deposit, with additional drilling at the Monjas zone to commence later in 2020

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.

B2Gold is currently completing approximately 42,500 metres of infill drilling at Gramalote Ridge to convert existing Inferred Mineral Resources to an Indicated category, and 7,645 metres of geotechnical drilling for site infrastructure.

Gramalote Project Mineral Resource Estimate

The Mineral Resource estimate for the overall Gramalote Project (100% basis), effective December 31, 2019, within a pit shell run at a gold price of $1,500 per ounce includes:

PEA Overview

The Gramalote Project is located in central Colombia, approximately 230 kilometres ("km") northwest of Bogota and 120 km northeast of Medellin, in the Province of Antioquia which has expressed a positive attitude towards the development of responsible mining projects in the region. The PEA was prepared by B2Gold and evaluates recovery of gold from a an open-pit mining operation that will move up to 143,000 tonnes per day ("tpd") (50.0  Mtpa), with a 30,137 tpd  (11.0 Mtpa) processing plant that includes crushing, grinding, flotation, with fine grinding of the flotation concentrate and agitated leaching of both the flotation concentrate and the flotation tails, followed by a carbon-in-pulp recovery process to produce doré bullion.  The PEA is based solely on production from the Gramalote Ridge deposit and does not include potential production from the nearby Trinidad deposit, which has a current Inferred Mineral Resource estimate (see above), and the Monjas West zone. The Mineral Resource estimate for Gramalote Ridge that forms the basis for the PEA includes Indicated Mineral Resources of 70,110,000 tonnes grading 0.92 g/t gold for a total of 2,070,000 ounces of gold and Inferred Mineral Resources of 79,030,000 tonnes grading 0.79 g/t gold for a total of 2,010,000 ounces of gold.

The PEA updates and enhances the previous studies on the Gramalote Project in several areas, including:

  • For Gramalote Ridge, additional drilling has been completed and a new Mineral Resource model has been developed
  • The PEA is based solely on Gramalote Ridge Mineral Resources, where previous studies included mining and processing ore from the Trinidad deposit and the Monjas West zone
  • Recent metallurgical test work has resulted in slightly lower processing costs and improved economics
  • The new Mineral Resource model for Gramalote Ridge includes new interpretations of higher grade ore zones and has allowed more efficient mine optimization, which has resulted in higher grade ore being fed to the plant during the first years of production, significantly improving project economics
  • Due to better defined high-grade zones in Gramalote Ridge in the block model, the overall gold grade for the PEA is 0.85 g/t, which is significantly higher than previous studies

Accelerated mining is planned in the early years of production to provide higher grade feed to the plant while stockpiling lower grade material. The final four years of plant feed are from low-grade stockpiles and oxide ore. Oxide ore, which only makes up about 3% of the plant feed, will be stockpiled and processed at the very end of the project life as blending this material with the fresh ore does not yield optimal gold recoveries.  

The PEA assumptions include revenues using a gold price of $1,350 per ounce and current prices for fuel, reagents, labour, power and other consumables. The key parameters of the PEA are presented in the following table (100% basis):

LoM all-in costs (AISC and pre-production capital costs) ($/oz gold)


Average LoM mining cost ($/t mined)


Average LoM processing cost ($/t processed)


Based on the positive results from the PEA, B2Gold believes that the Gramalote Project has the potential to become a large, low-cost open-pit gold mine, subject to completion of ongoing infill drilling and the results of a final feasibility study expected by the end of 2020. The Gramalote Project has several key infrastructure advantages, including:

  • Reliable water supply – high rainfall region and located next to the Nus River
  • Adjacent to a national highway, which connects directly to Medellin and to a major river with port facilities, capable of bringing supplies by barge to within 70 km of the site
  • Proximity to the national electricity grid with ample low-cost power and a stable record of hydroelectric power
  • Skilled labour workforce within Colombia

In addition, B2Gold expects the Gramalote Project to benefit from several key operational advantages, including:

  • Excellent metallurgical characteristics of the ore, which results in high recovery rates at low processing costs
  • Relatively low strip ratio in the mine (1.9:1)
  • Ability to mine and process higher grade ore in the initial years of the mine life resulting in improved project economics

The PEA is subject to a number of assumptions and risks, including among others, that a Modified Environment Impact Study and a Modified Project Implementation plan will be approved within the required timeline, all required permits and other rights 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.

Economic Sensitivities

Gramalote is a large, low-grade, low-cost project and sensitive to the gold price, as demonstrated in the following table:

Project Next Steps

B2Gold and AGA have agreed on a budget for the feasibility study on the Gramalote Project of approximately $37 million through the end of 2020. This budget will fund 42,500 metres of infill drilling to convert existing Inferred Mineral Resources to the Indicated category, and 7,645 metres of geotechnical drilling 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 estimate, detailed mine planning, ongoing environmental studies, additional metallurgical test work, engineering and detailed economic analysis.

The Gramalote joint venture will continue to advance resettlement programs, establish coexistence programs for small miners, work on health, safety and environmental projects and continue to work with government and local communities on social programs. B2Gold, as manager, plans to continue the feasibility work with the goal of B2Gold completing a final feasibility study by December 31, 2020. Due to the amount of work completed by AGA over the past several years, including extensive testing programs, the work with local communities and small miners, and the high level of engineering performed in 2017 for an internal study, the work remaining to reach final feasibility is not extensive. The main work program for feasibility is infill drilling to confirm and upgrade the Inferred Mineral Resources to the Indicated category.

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 and operate the mine on behalf of the joint venture.

Non-IFRS Measures

This news release includes certain terms or performance measures commonly used in the mining industry that are not defined under International Financial Reporting Standards ("IFRS"), including "cash operating costs" and "all-in sustaining costs" (or "AISC"). Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS and should be read in conjunction with B2Gold's consolidated financial statements. Readers should refer to B2Gold's Management Discussion and Analysis, available on the Websites, under the heading "Non-IFRS Measures" for a more detailed discussion of how B2Gold calculates certain of such measures.

Cautionary Note to United States Investors

The disclosure in this news release was prepared in accordance with Canadian National Instrument 43-101 ("NI 43-101"), which differs significantly from the current requirements of the SEC set out in Industry Guide 7. Accordingly, such disclosure may not be comparable to similar information made public by companies that report in accordance with Industry Guide 7. In particular, this news release may refer to "mineral resources," "indicated mineral resources" or "inferred mineral resources". While these categories of mineralization are recognized and required by Canadian securities laws, they are not recognized by Industry Guide 7 and have not historically been permitted to be disclosed in SEC filings by U.S. companies subject to Industry Guide 7. U.S. investors are cautioned not to assume that any part of a "mineral resource," "indicated mineral resource" or "inferred mineral resource" will ever be converted into a "reserve." In addition, this news release uses the terms "reserves" and "mineral reserves" which are reported by the Company under Canadian standards and may not qualify as reserves under Industry Guide 7. Under Industry Guide 7, 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 Industry Guide 7. "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. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian reporting standards; however, Industry Guide 7 normally only permits issuers to report mineralization that does not constitute "reserves" by Industry Guide 7 standards as in-place tonnage and grade without reference to unit measures. 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 subject to Industry Guide 7 have not generally been permitted to disclose economic projections for a mineral property in their SEC filings prior to the establishment of "reserves." Historical results or feasibility models presented herein are not guarantees or expectations of future performance.
