Twangiza Update

Q3 2017's results for Twangiza, in comparison to Q3 2016 and the second quarter ("Q2") of 2017, are as follows:

Operating metrics		Units	Q3 2017	Q3 2016	% Change	Q2 2017	% Change	Q3 YTD 2017	Q3 YTD 2016	% Change
Total material mined		Tonnes	2,841,142	1,420,698	100%	2,997,030	-5%	7,905,053	3,352,883	136%

Gold production		Ounces	30,297	25,187	20%	19,588	55%	73,000	78,043	-6%

Twangiza's gold production in Q3 2017 increased by 55% compared to Q2 2017, due to having access to enough oxide feed material to blend with the upper transition (soft non-oxide) material in the pit. As a result of adopting the recommendations from a process review, all lower transition and fresh ores were stockpiled to be treated after the installation of the appropriate size reduction processing route.

The process recoveries at Twangiza improved by 11% over Q2 2017 due to better blend proportions of oxide and upper transition ores being received by the plant.

Process engineering studies are currently in progress to design the appropriate Semi-Autogenous Grinding ("SAG") mill to efficiently treat both the lower transition and fresh ores both of whose hardness is beyond the capabilities of the current mills.

The benefits of the injection of new and matching fleet at Twangiza during the first half of 2017 into the production line, has demonstrated Twangiza's ability to expose more ore faces for the efficient supply of the proportions of feed required for blending.

Namoya Update

Q3 2017 results for Namoya, in comparison to Q3 2016 and Q2 2017, are as follows:

Operating metrics		Units	Q3 2017	Q3 2016	% Change	Q2 2017	% Change	Q3 YTD 2017	Q3 YTD 2016	% Change
Total material mined		Tonnes	2,659,570	2,708,374	-2%	2,238,654	19%	7,282,882	6,596,070	10%

Gold production		Ounces	18,533	28,190	-34%	19,151	-3%	60,783	69,199	-12%

Following the installation of additional primary fleet at Namoya during the latter part of Q2 2017, Namoya was able to move more material out of the pits in the middle of Q3 2017.

The production shortfall at Namoya for Q3 2017 relates to the temporary shutdown and evacuation of staff during the first week of July (press release dated July 3^rd, 2017) and a shortage of major supplies while the Company concluded its latest financing (press release dated July 17^th, 2017). As well, the ongoing closure of road access to Namoya (press release dated September 25^th, 2017) continues to impact Namoya with mining operations still being suspended. Spraying at the heap leach section at Namoya is continuing, to recover gold from the processed ore stacked before mining operations were suspended.

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.

Gold Delivery Deferrals

The Company also announces that, in order to provide additional liquidity for the Company's operations, the Company has agreed with certain affiliates of Baiyin International Investment Ltd. ("Baiyin") and an entity controlled by Gramercy Funds Management LLC ("Gramercy"), to defer certain gold deliveries that would otherwise be due to Gramercy and such Baiyin affiliates (collectively, the "Gold Deferrals"). Specifically, all gold delivery obligations due from mid-September 2017 to end December 2017 under the existing Twangiza gold stream agreement with a Baiyin affiliate (the "Twangiza Stream") will be deferred, as will all gold delivery obligations due from September 2017 to end December 2017 under the existing Namoya gold forward sale agreement entered into in April 2017 with a Baiyin affiliate and Gramercy (the "Namoya GFSA").

In the case of the Twangiza Steam, the deferred gold deliveries, plus additional ounces in order to retain the implied internal rate of return ("IRR") of the original terms of such agreement, are to be delivered over the first 8 months of 2018 (together with the normal gold deliveries required as per the original terms of the Twangiza Stream). In the case of the Namoya GFSA, the remaining scheduled monthly gold deliveries under the Namoya GFSA have been increased to include the deferred gold deliveries, plus additional ounces in order to retain the IRR of the original terms of such agreement (such that the remaining scheduled monthly gold deliveries under the Namoya GFSA have been increased from 1,438.904 ounces per month to 1,649.50 ounces per month). Assuming a gold price of US$1,250 per ounce during the four month deferral period (net of the US$150 per ounce gold transfer price in the case of the Twangiza Stream) the estimated value of the deferred gold deliveries under the Twangiza Steam and the Namoya GFSA is approximately US$11.3 million in the aggregate.

The Gold Deferrals have been entered into in order to provide the Company with additional short term liquidity while it continues to explore opportunities to address its ongoing operational and working capital challenges, as discussed in the Banro management's discussion and analysis for the period ended June 30, 2017. Also in order to facilitate that process, the Company's board of directors has formed a Special Committee to identify and make recommendations to the board of directors concerning financing and other strategic options (including the restructuring or refinancing of existing obligations) that may be available to the Company. In light of the potential involvement of the Company's major shareholders and debtholders in any such transactions, the Special Committee is comprised of directors (Richard Brissenden, Robert Rorrison and Derrick Weyrauch) who are independent of such shareholders/debtholders. The Gold Deferrals were approved by the Company's board of directors on the recommendation of the Special Committee.

Banro Corporation is a Canadian gold mining company focused on production from the Twangiza and Namoya mines, which began commercial production in September 2012 and January 2016 respectively. 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 kilometres long Twangiza-Namoya gold belt in the South Kivu and Maniema Provinces of the Democratic Republic of the Congo (the "DRC"). All business activities are followed in a socially and environmentally responsible manner.
