TORONTO, ONTARIO—(Marketwired - April 13, 2017) - Banro Corporation (“Banro” or the “Company”) (NYSE MKT:BAA)(TSX:BAA) announces preliminary operating results for the first quarter of 2017.

Twangiza Update

Mining productivity advanced during the first quarter of 2017, with Twangiza continuing to move increased amounts of waste material to advance the mining program in order to increase ore deliveries in future quarters. Recoveries at Twangiza during the first quarter of 2017 continued to be impacted by the blend of ore types based on available run-of-mine ore. The combined impact of lower than expected mill throughput partially offset by modestly higher head grades and recoveries during the first quarter resulted in the gold production at Twangiza decreasing from the previous quarters.

The first quarter 2017 results for the Twangiza mine, in comparison to the first and fourth quarter of 2016, are as follows:

Operating Metrics Units Q1 2017 Q1 2016 % Change Q4 2016 % Change
Total material mined Tonnes 2,066,882 886,905 133% 1,601,524 29%

Head grade g/t Au 2.70 2.61 4% 2.85 (5%)
Recovery % 68.4 77.2 (11%) 71.0 (4%)
Strip ratio t:t 2.43 0.93 161% 2.20 10%
Gold production Ounces 23,115 26,638 (13%) 26,395 (12%)

Namoya Update

Mining productivity and heap leach ore tonnes stacked both decreased in the first quarter of 2017 as compared to the previous periods mainly because of the reduced availability of certain critical supplies. The overall reduced operating activities from both mining and processing operations during the first quarter impacted gold production; however, the decrease in gold production levels was limited because of continued gold recovery from material stacked in previous periods.

The first quarter of 2017 results for the Namoya mine, compared to the first and fourth quarter of 2016, are as follows:

Operating Metrics Units Q1 2017 Q1 2016 % Change Q4 2016 % Change
Total material mined Tonnes 2,384,658 1,982,555 20% 2,950,552 (19%)
Total ore mined Tonnes 487,629 378,967 29% 666,037 (27%)
Total ore stacked Tonnes 507,422 414,120 23% 653,049 (22%)
Head grade g/t Au 2.08 1.94 8% 1.78 18%
