Drilling at Namoya intersects further significant mineralization, including 11.0 metres grading 4.73 g/t Au from 17.0 metres, 5.0 metres grading 21.05 g/t Au from 29.0 metres, 29.0 metres grading 1.80 g/t Au from 17.0 metres, 11.0 metres grading 4.37 g/t Au from 0.0 metres, and 16.0 metres grading 3.00g/t Au from 6.0 metres. 11.0 metres grading 4.73 g/t Au from 17.0 metres, 5.0 metres grading 21.05 g/t Au from 29.0 metres, 29.0 metres grading 1.80 g/t Au from 17.0 metres, 11.0 metres grading 4.37 g/t Au from 0.0 metres, and 16.0 metres grading 3.00g/t Au from 6.0 metres. New mineralized zone, Bulawayo, discovered at Namoya. Banro Corporation ("Banro" or the "Company") (NYSE MKT:BAA)(BAA.TO) is pleased to announce the discovery of a new mineralized zone and to provide updates on its ongoing near-mine reverse circulation (RC) drilling program at its Namoya gold mine.
Commenting on these results, Banro President and CEO, John Clarke said, "We are excited by these significant intersections coming from the Namoya Summit Hanging Wall Zone and the Bulawayo Prospects. These intersections occur in similar geological settings to adjacent deposits and offer a good opportunity to replenish and grow our resources and reserves. We plan to carefully evaluate these zones of mineralization and update our year-end (2016) mineral resources and reserves."
Interim Program Update
The current exploration drilling program at Namoya commenced in August 2016. The priorities were to grow Namoya's mineral resources in the short term and to test new targets. In summary, the work focused on:
Delineation and infill drilling of the recently discovered Namoya Summit Hanging Wall Zone (see Banro press release of February 24, 2016). Evaluation of the in-pit Inferred Mineral Resource for conversion into a higher confidence category for inclusion in the mining blocks at the Kakula and Muviringu deposits. Exploration drilling at the Bulawayo and Seketi targets, which led to the discovery of new zones of mineralization. Following the said February 24, 2016 press release, 60 RC holes totaling 4,592 metres were drilled. An update of the interim drilling program is provided below.
Namoya Summit Hanging Wall Zone
RC drilling at the Namoya Summit Hanging Wall Zone continued to define the mineralization zones and is assisting with the definition of the resource. From August 2016, when drilling resumed at Namoya (and after the last news release on the Namoya Summit Hanging Wall Zone), 19 RC holes totaling 1,765.00 metres were drilled at the Namoya Summit Hanging Wall Zone. Overall, 30 RC holes totaling 2,626 metres were drilled at the hanging wall zone. Some of the significant intersections from the current program include the following:
Hole NRC180 intersected 3.00 metres grading 2.90 g/t Au from 50.00 metres and 2.00 metres grading 3.39 g/t Au from 72 metres, Hole NRC181 intersected 26.00 metres grading 1.21 g/t Au from 55.00 metres, Hole NRC183 intersected 11.00 metres grading 4.73 g/t Au from 17.00 metres, Hole NRC185 intersected 4.00 metres grading 1.85 g/t Au from 38.00 metres, Hole NRC193 intersected 4.00 metres grading 1.76 g/t Au from 66.00 metres and 6.00 metres grading 2.02 g/t Au from 102.00 metres, Hole NRC195 intersected 4.00 metres grading 2.62 g/t Au from 101.00 metres, Hole NRC196 intersected 2.00 metres grading 5.05 g/t Au from 14.00 metres, 5.00 metres grading 21.05 g/t Au from 29.00 metres, 6.00 metres grading 1.88 g/t Au from 67.00 metres and 7.00 metres grading 1.45 g/t Au from 79.00 metres.

Bulawayo and Seketi Exploration Drilling
Exploration drilling at the Bulawayo and Seketi targets led to the discovery of new zones of bedrock mineralization from previous auger drilling intersections. Seventeen (17) RC holes totaling 1,215 metres were drilled at the Bulawayo target and 7 RC holes totaling 502 metres were drilled at the Seketi target.
The Bulawayo prospect is located approximately 100 metres south of the Mwendamboko deposit, and is considered as a footwall zone of mineralization extending from the Muviringu deposit to the west. The Seketi prospect is located approximately 700 metres south of the Mwendamboko deposit. Significant intersections from the initial RC drilling program at Bulawayo and Seketi include the following:
Hole NRC149 intersected 29.00 metres grading 1.80 g/t Au from 17.00 metres, Hole NRC157 intersected 3.00 metres grading 2.23 g/t Au from 58.00 metres, HoleNRC158 intersected 7.00 metres grading 4.91 g/t Au from 30.00 metres, Hole NRC159 intersected 11.00 metres grading 4.37 g/t Au from 0.00 metres, Hole NRC163 intersected 3.00 metres grading 4.46 g/t Au from 0.00 metres, Hole NRC159B intersected 11.00 metres grading 1.79 g/t Au from 0.00 metres, Hole NRC164 intersected 5.00 metres grading 2.13 g/t Au from 56.00 metres, Hole NRC168 intersected 11.00 metres grading 2.01 g/t Au from 43.00 metres, Hole NRC169 intersected 18.00 metres grading 1.62 g/t Au from 0.00 metres and 15.00 metres grading 2.23 g/t Au from 56.00 metres, Hole NRC176 intersected 5.00 metres grading 2.09 g/t Au from 37.00 metres. A locality map of the reported drill holes can be found on the Company's website at: https://www.banro.com/assets/docs/Bulawayo-SeketiProspectLocationMap-Mar2017.pdf
In-pit Resource Conversion Drilling
In-pit RC drilling at the Kakula and Muviringu deposits targeted zones with a paucity of information, categorised as inferred blocks and not accounted for as mineral reserve. The aim was to convert those zones to the Indicated Resource category for inclusion in the mine plan. Five (5) RC holes totaling 354 metres were drilled at Muviringu while 12 RC holes totaling 756 metres were drilled in the Kakula pit.
Significant mineralization intersections from the program include the following:
Hole NRC139 intersected 16.00 metres grading 3.00 g/t Au from 6.00 metres, Hole NRC142 intersected 6.00 metres grading 1.61 g/t Au from 2.00 metres, 2.00 metres grading 5.36 g/t Au from 13.00 metres, Hole NRC150 intersected 12.00 metres grading 1.98 g/t Au from 48.00 metres and 21.00 metres grading 1.63 g/t Au from 67.00 metres, Hole NRC151 intersected 8.00 metres grading 1.78 g/t Au from 71.00 metres, Hole NRC153 intersected 6.00 metres grading 1.13 g/t Au from 89.00 metres. Hole NRC155 intersected 6.00 metres grading 2.11 g/t Au from 0.00 metres, and 7.00 metres grading 4.60 g/t Au from 46.00 metres. Drilling inclinations ranged from -52° to -76° with the majority of holes inclined at -60°. RC holes were planned in fences spaced around 40 metres at Bulawayo and Seketi, while the Kakula, Muviringu and Namoya Summit Hanging Wall drilling used fences ranging from 15-40 metres. Drill azimuth was towards the 225° at the Namoya Summit, Kakula and Muviringu deposits and Bulawayo prospect. At Seketi, drilling was oriented at an azimuth of 45°. It is estimated that the true width of mineralization is approximately 85% of the mineralization intersections in the drill holes.
