Project Overview

The Otjikoto gold project is located approximately 300 kilometres north of Windhoek, the capital of Namibia, and is owned 92% by B2Gold and 8% by EVI Gold (Pty) Ltd, a Namibian black empowerment group. The property has excellent infrastructure. It is located adjacent to a major paved highway and drilling has outlined water on site well in excess of the LOM requirements.

The Otjikoto project will be developed as an open pit mine, where run-of-mine ore will be trucked to the plant, crushed, and then treated in a grinding circuit utilizing conventional SAG and ball mills, and a carbon in leach ("CIL") recovery process.

The mine plan is based on probable mineral reserves of 29.4 million tonnes at a grade of 1.42 g/t containing 1,341,000 ounces of gold at a stripping ratio of 5.59:1 to be mined over an initial 12 year period. All necessary government permits and licenses have been received. Construction has commenced and is scheduled for completion in the fourth quarter of 2014 when mill production will begin.

The current average annual production for the first five years is approximately 141,000 ounces of gold per year at an average operating cash cost of $525 per ounce and for the LOM approximately 112,000 ounces of gold per year at an average operating cash cost of $689 per ounce. The total pre-production capital costs are estimated to be $244.2 million (see pre-production capital costs table below for further details).

The plant facility and support infrastructure will be built to support a plant expansion from the initial processing capability of 2.5 million tonnes per annum to 3.0 million tonnes with minimal additional capital expenditure.

The financial modeling for the Otjikoto project indicates robust economics. At a gold price of $1,550 per ounce, the project is projected to yield a positive after-tax NPV of $243.4 million at a discount rate of 5%. The IRR after-tax is 23.6%. The project has a 32 month pay-back period after first gold production. See appendix 1 at the end of this news release for additional project assumptions and parameters.

The Otjikoto gold project has excellent exploration potential. An aggressive exploration drilling program continues on the success of the high grade Wolfshag zone discovered in late 2012, that is adjacent to the planned Otjikoto pit. These positive results indicate significant exploration upside and the potential to outline additional resources which could lead to the expansion of through-put capacity and increase annual average gold production.

A trade-off study with metallurgical testwork and economic evaluations was conducted to evaluate the optimal processing design for the Otjikoto project. Based on the findings of metallurgical testwork, the study recommended utilizing a whole ore carbon in leach ("CIL") recovery system rather than the previous concept of utilizing a flotation recovery circuit. While this change results in increased pre-construction capital costs of approximately $50 million, it significantly improves project economics by increasing gold recoveries by more than 5% over those achieved by a floatation circuit.

The Company has accepted a committed letter of offer from Macquarie Bank Limited ("Macquarie Bank") for a fully underwritten $150 million secured Facility for a four year term with a final repayment date of March 31, 2017.

B2Gold's strong financial position and anticipated future operating cash flows combined with the recently signed committed Facility term sheet are expected to provide the Company with sufficient financial resources to bring the Otjikoto project into production and fund all additional expenditures projected for 2013.

Mining, Production and Resources

The mineral reserves established for the Otjikoto project are based only on the indicated mineral resource and are therefore eligible for conversion to the Probable mineral reserve category. The mineral reserve estimate was calculated based on a gold price of $1,350 and resulted in a cut-off grade of approximately 0.4 g/t. The mineral reserve estimate is as follows:

--  Probable reserve of 29.4 million tonnes at a grade of 1.42 g/t gold
    containing 1.34 million ounces of gold at a stripping ratio of 5.59:1
    derived from the ultimate pit. The reserve is summarized in the table
    below 

--  These mineral reserves have been generated in accordance with the
    guidelines developed by the National Instrument 43-101

An elevated cut-off strategy was used to increase production in the early years, shorten the payback period and improve overall project economics. An ore grade of 0.6 g/t gold was applied in the production schedule which leads to a projected 6.5 million tonne low grade stockpile for ore with a grade ranging from 0.4 g/t gold to 0.6 g/t gold. The low grade ore stockpile will be processed primarily during the last two years of the mine life.

The mineral resource at the Otjikoto project at a 0.4 g/t gold cut-off within a $1,350 per ounce optimized pit is:

Process and Metallurgy

As part of the FS, an extensive testwork programme was undertaken in order to establish the process design parameters, formulate the process flowsheet and evaluate ore variability.

Based on the findings of this testwork programme the process plant design parameters were determined. The design basis of the selected process is based on a whole ore leach flowsheet at a nominal treatment rate of 2.5 million tonnes per annum and a 25% design factor on the crusher, conveyors, mills, mainstream pumps and piping, cyanide destruction circuit and thickeners to allow for a possible future expansion to 3.0 million tonnes per annum with minimal additional capital expenditure. The process plant and design as detailed in the FS is based on the recovery of gold by gravity concentration followed by an intensive leach circuit, and a cyanide leach process for gold recovery from gravity tailings.

Run-of-Mine ore from the open pit operations will be delivered by 100 tonne trucks to the primary crusher. The ore will be fed to a crushing plant which consists of a gyratory crusher and conveyor system that feeds the coarse ore stockpile. Material will be reclaimed from the stockpile and treated in a grinding circuit which is comprised of a primary SAG mil and a secondary ball mill. The entire ball mill discharge stream will be treated in a gravity concentration circuit for recovery of coarse gold. The gravity concentrate will be processed in an intensive leach circuit.

The gravity tailings product is thickened to 45% solids and treated in a cyanide leach circuit. The leach product stream is pumped to a carbon in pulp ("CIP") circuit for recovery of gold in solution. The tailings stream from the CIP circuit is treated in a cyanide destruction circuit using the SO2/Air process, before being pumped to a lined tailing storage facility.

Gold is recovered from the CIP circuit loaded carbon in a split AARL elution circuit. Gold solutions from the gravity intensive leach circuit and elution circuit are treated in an electrowinning process followed by smelting to produce Dore bars. Final recoveries of gold are projected at 95.6%.

Mine Operating Cash Cost

Operating cash costs are expected to average $524 per ounce of gold for the first five years of the project and $689 per ounce of gold over the 12 year LOM. The expected average site operating cash cost is $33.21 per tonne processed. The operating cost estimate was prepared by B2Gold and engineering contractors supporting the feasibility study and is based on actual or estimated supply costs, actual and estimated logistics costs, engineered productivity / production rates, and equipment operating and maintenance costs from other operating mines and equipment manufacturers.

Pre-Production Capital Cost Estimates

The requirement of the FS was to produce a capital estimate accurate to +/- 10%. The estimate is base dated December 2012. The capital costs for the project are summarized in the table below.

The pre-production capital cost estimate for the Otjikoto project's processing plant and infrastructure was compiled by the project management team supported by the primary feasibility consultant, DRA Mineral Projects Ltd, and other FS engineering contractors that contributed significantly to the capital cost estimate form and basis. DRA Mineral Projects Ltd provided the plant process and infrastructure capital costs. VBKOM Consulting Engineers Namibia provided the form and basis for the surface mining capital costs inclusive of the mining equipment and mine development costs. Epoch Resources (Pty) Ltd provided the designs and quantities for the tailing pond cost estimates.

The total pre-production capital costs are estimated to be $244.2 million, which includes working capital for supplies, taxes and owners costs.

A trade-off study with metallurgical testwork and economic evaluations were conducted to evaluate the optimal processing design for the Otjikoto project. Based on the findings of metallurgical testwork, the study recommended utilizing a whole ore carbon in leach ("CIL") recovery system rather than the previous concept of utilizing a flotation recovery circuit. While this change results in increased pre-construction capital costs of approximately $50 million, as outlined above, it significantly improves project economics by increasing gold recoveries by more than 5% above recoveries achievable by a floatation circuit.

In addition, in order to attain higher gold production in the initial years of production and optimize project economics, the Company plans to expend approximately $33 million on extensive pre-production waste stripping and ore stockpiling during construction.

Corporate Social Responsibility ("CSR")

B2Gold's CSR is a key aspect of every project and B2Gold Namibia has worked closely with communities around the Otjikoto project area to develop a CSR program that benefits all stakeholders. Through a transparent mechanism, B2Gold Namibia is supporting community driven projects in public health, education, development of small to medium enterprises and environmental conservation. Projects included scholarships to historically disadvantaged students, support to the Namibian Institute of Mining and Technology, a partnership with the Cheetah Conservation Foundation to monitor and protect endangered species, identification of potential small to medium enterprises within the communities where our workers live, support of educational needs with the Ministry of Education, support of programs that help at risk teens, and providing equipment and facilities to support local medical needs.

Project Implementation

The Otjikoto project execution plan encompasses project management by B2Gold and utilizes a delivery method comprised of a combination of Engineering, Procurement, and Construction combined with multiple prime engineering contracts and some self-performed owner construction.

Engineering and procurement will be managed from the B2Gold corporate offices in Vancouver, British Columbia, Canada with construction management occurring from the Otjikoto project site. The majority of equipment and supplies will be sourced from South Africa, North America or European suppliers and will be ocean shipped to the seaport at Walvis Bay, Namibia, with subsequent overland delivery utilizing contracted commercial trucking firms.

The site development will take place year round, utilizing a work force of experienced Namibian nationals, trained and supervised by Namibian and expatriate supervision. Many of the expatriate supervisors have worked on previous successful projects associated with B2Gold and Bema Gold Corporation.

Logistics will be supported from the existing B2Gold support structure in place and operating in Namibia. Construction activities have commenced. The mills and primary crusher were ordered in December 2012. The grinding mills, crushing equipment and the construction man camp have been secured and partial payment has been made and they are undergoing fabrication and shipping. The generators will be procured in February 2013. The process plant is expected to be ready to receive ore in the fourth quarter of 2014.

Committed Letter of Offer for a $150 Million Revolving Corporate Credit Facility

B2Gold is pleased to announce that it has accepted a committed letter of offer from Macquarie Bank for a fully underwritten $150 million secured Facility. Macquarie Bank is the Sole Underwriter and the Facility Agent. The syndicate will include HSBC Securities (USA) Inc. as a Lead Arranger and HSBC Bank USA, National Association has committed to fund $50 million of the Facility.
