TWANGIZA MINE

The Company's objectives for the Twangiza Mine in 2013 were to increase throughput, recovery rates and gold production at Twangiza through its plant optimization and expansion project. Plant modifications, including a new crusher and mineral sizer as well as additional elution tanks, were planned to increase design throughputs to up to 1.7Mtpa, increasing gold production to the 8,000-10,000oz/month range by Q4 2013. Actual results for the year ended December 31, 2013 were approximately 1.0Mt of ore processed at the plant achieving an average recovery of 83.8% (as compared to approximately 82% during commercial production in 2012) to produce an average of 6,883oz/month (as compared to 6,296/oz month during the four months of commercial production in 2012). Although the annual throughput and average monthly production was less than expected, the Company did observe an increase in throughput (on an annualized basis), recovery rate, and monthly production during the fourth quarter of 2013 as the plant expansion project neared its completion.

Mining

A total of 4,115,657 tonnes of material (2012 - 3,014,926 tonnes) were mined during the year ended December 31, 2013. Total ore mined was 1,758,972 tonnes (2012 - 1,731,329 tonnes), which was within less than a 1% difference compared to management's forecast for the year. Although the volume of ore mined was as expected, the higher strip ratio (1.35 compared to a forecasted strip of 0.34) was due to significantly greater waste material having been moved during the year. This was primarily the result of two contributing causes: the first contributor to the higher waste tonnage mined was the mining of some areas beneath and outside the grade control envelope originally modeled as ore were converted to marginal ore or waste after field observations; the second contributing factor was the mining of more waste outside of one particular pit wall in order to stabilize the wall itself. Similar to 2012, the higher strip ratio was also a function of adjustments to the mining plan in order to optimize grades delivered to the mill during periods of low throughput.

Processing & Engineering

For the year ended December 31, 2013, the plant at the Twangiza Mine processed 1,023,981 tonnes of ore (2012 - 974,399 tonnes or 75% of 1.3Mtpa design capacity) or 60% of the future expected annual design throughput of up to 1.7Mtpa design capacity resulting from the plant expansion. The Company experienced continued issues with regards to the front-end to the plant even after upgrading the mineral sizer (primary crusher). Throughput was negatively impacted during rainy periods and seriously impacted during heavy rains. Given the issues experienced with wet material on the front-end of the plant and the resulting significant adverse impact to overall throughput, the Company pursued an initiative to provide roofing above the ROM (Run-of-Mine) pad in late 2013 to be able to secure adequate dry stockpile material at any point in time. Recoveries during the year were at an average rate of 83.8% (2012 - 81.9%), showing an improvement from the prior year primarily as a result of the longer residence time of material with the installation of additional tank capacity as part of the plant upgrade. The lower than forecasted average monthly gold production for the year was primarily a result of the lower throughput for the year ended December 31, 2013.

Twangiza Plant Optimization and Expansion

As of the date of this press release, the plant optimization and expansion project was practically complete, with the exception of the second elution system and the second carbon kiln.

As part of the plant expansion project, the mineral sizer (primary crusher) and both secondary and tertiary crushers were replaced with larger and more robust units. These units were installed and operational during the second quarter of 2013 with the sizer being installed later in June 2013.

The new carbon regeneration kiln demonstrated continuous improvement of carbon activities and subsequent absorption while the two new air blowers on the existing carbon-in-leach ("CIL") circuit have provided increased dissolved oxygen levels as expected.

The addition of the four new CIL tanks (which were installed during Q3 2013) followed by the refurbishment of the six original tanks is expected to bring recoveries to between 85% and 90% in 2014 at a design capacity of up to 1.7 Mtpa. The modification of the six original tanks was completed in Q4 2013.

The second complete (modular) elution system has been delivered and is currently on site being assembled. This will allow for two parallel streams of processing at the plant.

Sustaining Capital Activities

During the year ended December 31, 2013, and subsequently up to the date of this press release, the following progress was made in the key areas indicated below with respect to sustaining capital activities at the Twangiza Mine:

NAMOYA MINE DEVELOPMENT

The Namoya project consists of one exploitation permit covering an area of 172 square kilometres and is located in the Maniema Province in the east of the DRC, approximately 225 kilometres southwest of the town of Bukavu. The Company is nearing the completion of an open pit hybrid CIL/heap leach gold mine at Namoya. The Company experienced some delays in the construction of the mine which lead to cost overruns for the project. Given the delays experienced in the completion of construction of the plant at the Namoya Mine a plan was implemented in Q3 2013 to initiate trial stacking of ore on the completed leach pads. This plan consisted of bypassing the main Namoya ROM pad and transporting material directly to two mobile crushers which directly fed (including cement additions) the grasshoppers placed on the heap leach pads for stacking of ore. Construction of the Namoya Mine is expected to be completed by the end of April 2014 with commercial production expected at the end of Q2 2014. As of the date of this press release, the Namoya Mine is 98.45% complete.

Key Achievements in 2013

EXPLORATION

With Banro's primary focus on the enhancements at the Twangiza plant and the development at Namoya, exploration programs were curtailed in 2013 with a shift in focus towards low-cost exploration activities at both mine sites and sufficient low cost activities at Kamituga and Lugushwa to maintain a presence on the properties.

(i) Twangiza Property

The Company's Twangiza property consists of six exploitation permits covering an area of 1,156 square kilometres.

Exploration at Twangiza commenced in October 2005, and has included extensive geological mapping along the 3.5 kilometre long resource delineation of the north trending mining target, which hosts the two principal deposits of Twangiza Main and Twangiza North. The following table summarizes the changes in the Twangiza Mineral Resource and Mineral Reserve estimates from December 2012 to December 2013:

Total Proven and Probable 13.69 2.34 1.03

During 2013, exploration activities at Twangiza were focused on the Ntula-Mufwa corridor and prospects around Luntukulu. These activities involved auger drilling, geological mapping and an orientation stream sediments Bulk Leach Extractable Gold ("BLEG") program. In the third quarter of the year, field camps in these areas were shut down to conserve resources and direct focus on the Twangiza plant expansion and optimization project and completion of the Namoya Mine. Since the reallocation of resources, the Ntula and Luntukulu areas have been kept on a care and maintenance basis.

The 2014 exploration program will focus on Mufwa, Ntula, Kabare and Luntukulu. BLEG stream sediments sampling, geological mapping and follow-up auger drilling and trenching will be undertaken at Mufwa. There will be a focus on delineating additional extensions of the broad low grade mineralization at Ntula during the latter part of the year. Similar to Mufwa, grassroots exploration work will be undertaken in the Kabare prospect involving BLEG sampling, geological mapping and target generation activities. In the Luntukulu prospect, geological mapping and follow-up drill targets generation will be undertaken using auger drilling and trenching work with the aim of generating significant shallow drill targets for potential testing during the last quarter of the year.

Additional information regarding Twangiza is included in the technical report dated March 9, 2011 (as revised on March 24, 2011) and entitled "Economic Assessment NI 43-101 Technical Report, Twangiza Phase 1 Gold Project, South Kivu Province, Democratic Republic of the Congo". A copy of this report can be obtained from SEDAR at www.sedar.com and from EDGAR at www.sec.gov.

(ii) Namoya Property

The Company commenced exploration at Namoya in December 2004. Diamond drill holes have been completed together with extensive re-sampling of old mine adits along the 2.5 kilometre long, northwest trending mineralized zone which hosts the four main separate deposits of Mwendamboko, Muviringu, Kakula and Namoya Summit. Exploration is continuing to assess a number of other prospects, namely Kakula West, Seketi, Kangurube, Matongo and Filon B, all within two kilometres of the four main deposits, to further increase oxide ounces.

As reported in the third quarter of 2013, encouraging results from an infill drilling program at Namoya were released (see Banro press release dated July 15, 2013). No regional exploration was conducted during the last two quarters of the year with the focus mainly being on supporting the Namoya Mine development through grade control drilling and water supply borehole drilling. The exploration activities during the first two quarters of 2013 centered on refining the Namoya geological and mineralization model in preparation of a full Mineral Resource update. The exploration team was also tasked with assisting the development team in drilling works related to the construction site investigations.

The 2014 exploration activities at the Namoya project are planned to include:

  1. Undertake shallow brownfields resource drilling within the mine footprint at Namoya Summit, Kakula, Mwendamboko and Filon B to generate additional oxide resource for the Namoya plant.
  2. Undertake low cost exploration activities at the NW - SE extensions of Matongo, Kangurube

(a) Regional exploration work, including a stream sediment BLEG sampling program in the first half of 2014,
(b) Selective ground follow-up work at the Kibukila, G15 and Kobokobo prospects to enhance current interpretation and refine drill targets,
(c) Follow-up work on targets generated from the BLEG program in the second half of the year, and
(d) An in-house IP survey of a 2 square kilometer block at Kibikula to the north east of previous coverage.

(v) Regional Exploration Property

The Company's wholly-owned DRC subsidiary, Banro Congo Mining SARL, holds 14 exploration permits covering an aggregate of 2,638 square kilometres of ground located between and contiguous to the Company's Twangiza, Kamituga and Lugushwa properties and northwest of Namoya.

No ground exploration was undertaken during 2013 in respect of these 14 permit areas.

Using Banro's magnetic and radiometric data that was obtained in 2007, SRK (UK) Consulting Ltd. carried out an integrated qualitative interpretation and target generation work in 2009 on all the permit areas. The report by SRK was qualitative and was based on the magnetic and radiometric data signatures on a large scale only. No quantitative interpretation was done. In 2012, Banro mandated Spectral Geophysics to carry out quantitative reinterpretation of the airborne data to generate additional targets. By applying various filters and transformations to the data one could detect very subtle structures associated with the mineralization.

The 2014 exploration activities at the regional exploration properties are planned to include undertaking a regional scale fine sediment sampling (BLEG) within the exploration permit areas to zone vast land areas into high and low priority areas for management decision making.

Qualified Person

Daniel K. Bansah, the Company's Head of Projects and Operations and a "qualified person" as such term is defined in National Instrument 43-101, has approved the technical information in this press release.

NON-IFRS MEASURES

Management uses cash cost to monitor financial performance and provide additional information to investors and analysts. Cash cost does not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As cash cost does not have a standardized meaning, it may not be comparable to similar measures provided by other companies. However, the methodology used by the Company to determine cash cost per ounce is based on a standard developed by the Gold Institute, which was an association which included gold mining organizations, amongst others, from around the world.

The Company defines cash cost, as recommended by the Gold Institute standard, as all direct costs that the Company incurs relating to mine production, transport and refinery costs, general and administrative costs, movement in production inventories and ore stockpiles, less depreciation, depletion and royalties. Cash cost per ounce is determined on a production basis.

The Company defines all-in sustaining costs as all direct costs that the Company incurs relating to mine production, transport and refinery costs, general and administrative costs, movement in production inventories and ore stockpiles, less depreciation, depletion and royalties plus all sustaining capital costs (excluding exploration). All-in sustaining cost per ounce is determined on a production basis.

The Company defines gold margin as the difference between the cash cost per ounce disclosed and the spot price per ounce of gold at close of the reporting period.

Banro Corp. is a Canadian gold mining company focused on production from the Twangiza mine, which began commercial production September 1, 2012, and completion of its second gold mine at Namoya located approximately 200 kilometres southwest of the Twangiza gold mine. The Company's longer term objectives include the development of two additional major, wholly-owned gold projects, Lugushwa and Kamituga. The four projects, each of which has a mining license, are located along the 210 kilometre long Twangiza-Namoya gold belt in the South Kivu and Maniema provinces of the Democratic Republic of the Congo. Led by a proven management team with extensive gold and African experience, the initial focus of the Company is on the mining of oxide material, which has a low capital intensity to develop but also attracts a lower technical and financial risk to the Company. All business activities are followed in a socially and environmentally responsible manner.

Cautionary Note to U.S. Investors

The United States Securities and Exchange Commission (the "SEC") permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Certain terms are used by the Company, such as "Measured", "Indicated", and "Inferred" "Resources", that the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC. U.S. Investors are urged to consider closely the disclosure in the Company's Form 40-F Registration Statement, File No. 001-32399, which may be secured from the Company, or from the SEC's website at http://www.sec.gov/edgar.shtml.

Cautionary Note Concerning Mineral Resource and Mineral Reserve Estimates

The Mineral Resource and Mineral Reserve figures referred to in this press release are estimates and no assurances can be given that the indicated levels of gold will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While the Company believes that the Mineral Resource and Mineral Reserve estimates included in this press release are well established, by their nature Mineral Resource and Mineral Reserve estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that Mineral Resources can be upgraded to Mineral Reserves through continued exploration.

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 upgraded to an Indicated or Measured Mineral Resource as a result of continued exploration. Confidence in the estimate is insufficient to allow meaningful application of the technical and economic parameters to enable an evaluation of economic viability worthy of public disclosure (except in certain limited circumstances). Inferred Mineral Resources are excluded from estimates forming the basis of a feasibility study.

Cautionary Note Concerning Forward-Looking Statements

This press release contains forward-looking statements. All statements, other than statements of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, statements regarding estimates and/or assumptions in respect of future gold production, costs, cash flow and gold recoveries, Mineral Resource and Mineral Reserve estimates, potential Mineral Resources and Mineral Reserves and the Company's development and exploration plans and objectives) are forward-looking statements. These forward-looking statements reflect the current expectations or beliefs of the Company based on information currently available to the Company. Forward-looking statements are subject to a number of risks and uncertainties that may cause the actual results of the Company to differ materially from those discussed in the forward-looking statements, and even if such actual results are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on the Company. Factors that could cause actual results or events to differ materially from current expectations include, among other things: uncertainty of estimates of capital and operating costs, production estimates and estimated economic return of the Company's projects; the possibility that actual circumstances will differ from the estimates and assumptions used in the economic studies of the Company's projects; failure to establish estimated mineral resources and mineral reserves (the Company's mineral resource and mineral reserve figures are estimates and no assurance can be given that the intended levels of gold will be produced); fluctuations in gold prices and currency exchange rates; inflation; gold recoveries being less than those indicated by the metallurgical testwork carried out to date (there can be no assurance that gold recoveries in small scale laboratory tests will be duplicated in large tests under on-site conditions or during production) or less than those expected following the expansion of the Twangiza plant; uncertainties relating to the availability and costs of financing needed in the future; changes in equity markets; political developments in the DRC; lack of infrastructure; failure to procure or maintain, or delays in procuring or maintaining, permits and approvals; lack of availability at a reasonable cost or at all, of plants, equipment or labour; inability to attract and retain key management and personnel; changes to regulations affecting the Company's activities; the uncertainties involved in interpreting drilling results and other geological data; and the other risks disclosed under the heading "Risk Factors" and elsewhere in the Company's annual information form dated March 29, 2014 filed on SEDAR at www.sedar.com and EDGAR at www.sec.gov.

Any forward-looking statement speaks only as of the date on which it is made and, except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any forward-looking statement, whether as a result of new information, future events or results or otherwise. Although the Company believes that the assumptions inherent in the forward-looking statements are reasonable, forward-looking statements are not guarantees of future performance and accordingly undue reliance should not be put on such statements due to the inherent uncertainty therein.
