Banro Announces Q4 and Full Year 2015 Production Results and Declares Commercial Production at Namoya

TORONTO, ONTARIO--(Marketwired - Jan 11, 2016) - Banro Corp. ("Banro" or the "Company") (NYSE MKT:BAA)(TSX:BAA) announces operating results for the fourth quarter of 2015 and declares commercial production at Namoya.

HIGHLIGHTS

• Twangiza produced 30,440 ounces of gold in the fourth quarter of 2015, for annual production of 135,532 ounces of gold, an increase of 38% over 2014 production of 98,184 ounces
• Throughput at the Twangiza process plant achieved 101% of the 1.7 million tonnes per annum ("Mtpa") design capacity.
• Namoya declares commercial production effective January 1, 2016.
• Twangiza and Namoya produced a combined 46,341 ounces of gold during the fourth quarter of 2015, for 2015 annual gold production of 183,369 ounces, well within consolidated production guidance.

"The fourth quarter of 2015 was a critical time for Namoya, with the major goal being the commissioning of the new mining fleet. We are very pleased to announce that this was achieved in early December, which in turn has enabled the Company to declare commercial production at Namoya, effective January 1, 2016," said Banro President and CEO John Clarke.

"Meanwhile, Twangiza continued to perform well through the fourth quarter, with strong gold production results consistent with those of the first three quarters of the year. The outstanding and stable production profile achieved in 2015 provides the Company with a stable foundation for continuing improvements in operations. In particular, we look forward to Namoya making a growing contribution to the Company's results and to the benefits of having two fully operational plants in our Twangiza - Namoya gold belt."

Twangiza Update

Twangiza's efforts in 2015 were focused on increasing throughput and gold production at the processing plant. This was achieved through the successful blending of non-oxide material at increasing levels with oxide material. This initiative was accompanied by test trials, to evaluate potential expansion opportunities at the process plant. In 2016, efforts will shift to exploring opportunities to enhance production by building on the existing plant infrastructure, in particular expanding the crushing capacity as contemplated in the use of proceeds from the financing transactions as announced in Banro's December 31, 2015 press release.

Twangiza experienced above average rainfall conditions in the fourth quarter of 2015, exacerbated by the El Nino effect. This created higher levels of operational downtime in the mining operations, impacting mining productivity and ore face availability. Despite this, the Twangiza process plant operated as planned, achieving a full year of throughput that was above the design capacity level of 1.714 Mtpa, and representing an increase of 26% over fiscal 2014 (1.358 Mtpa).

Twangiza poured 30,440 ounces of gold in the fourth quarter, bringing 2015 annual production to 135,532 ounces of gold. This exceeds both the original and updated full-year production guidance for Twangiza for 2015.

Preliminary 2015 fourth quarter and full year production results for the Twangiza mine, in comparison to the same periods of 2014 and the previous quarter in 2015, are as follows:

Namoya Update

Continuing progress at Namoya over the fourth quarter, in particular the sustained production achieved during December when the full fleet was operational, led to the Company declaring commercial production, effective January 1, 2016.

Namoya also experienced significantly above average rainfall conditions in the fourth quarter of 2015 due to the arrival of El Nino. Mining activities progressively improved through the quarter as the new fleet made incremental contributions. The CAT 777 mining fleet, which was fully commissioned in early December, moved over 700,000 tonnes of material for the month, as compared with an average of approximately 369,000 tonnes for the first 11 months of 2015. The commissioning of the larger fleet represented the final step toward Namoya being able to operate in a manner consistent with management expectations. With continued increases in mining activity, it is expected that monthly stacking levels will quickly advance to design capacity levels.

Ore stacked for the fourth quarter of 2015 decreased from the third quarter to 383,913 tonnes. However, the quarterly total included 151,371 tonnes stacked in December, a significant improvement over November, when operations were severely impacted by poor rain conditions. The average grade of the material stacked in the quarter was 2.35 g/t Au, a marked increase from the third quarter, which relied on the processing of supplemental ore from low grade stockpiles due to the delay in receiving the mobile fleet. While stacking levels decreased from the third quarter of 2015, an increase in ore grade led to an overall increase of over 20% in gold content stacked quarter over quarter. With over 40% of this gold stacked in December, Namoya's gold production in the first quarter of 2016 is expected to realize the benefit of this higher-grade material. Total gold production at Namoya for the fourth quarter was 15,941 ounces.

Preliminary 2015 fourth quarter production results for the Namoya mine, compared to the previous quarter in 2015 and the same quarter of 2014, are as follows:

With Namoya declaring commercial production effective January 1, 2016, operating metrics for the mine will be reported beginning with the first quarter of 2016.

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 ("DRC"). All business activities are followed in a socially and environmentally responsible manner.
