Banro Receives Excellent Initial Metallurgical Results From its Namoya Project

August 21st, 2006

Independent testwork on 12 representative samples from the Mwendamboko, Kakula and Namoya Summit deposits indicate 94.46% to 99.61% of the contained gold is expected to be recoverable from conventional carbon-in-leach processing.

Toronto, Canada August 21, 2006: Banro Corporation (“Banro” or the “Company”) (AMEX - “BAA”; TSX - “BAA”) is pleased to announce initial metallurgical test results from the Company’s wholly-owned Namoya project, located on the Twangiza-Namoya gold belt in the Democratic Republic of the Congo (the “DRC”).

Twelve composite drill hole samples from the main deposits of Mwendamboko, Kakula and Namoya Summit were submitted to SGS Lakefield in South Africa for initial metallurgical testwork to determine the amount of contained gold that can be extracted using conventional CIL (carbon-in-leach) processing. The diagnostic testwork procedure involved the sequential solubilizing of the least-stable minerals via various pre-treatments, and extraction of the associated gold by cyanidation/CIL.

Results from this testwork are summarised in the table below:
------------------------------------------------------------

Mwendamboko    NMTOX-02    Oxide        4.31      97.57%
Mwendamboko    NMTOX-03    Oxide        1.60      94.46%
Mwendamboko    NMTOX-04    Oxide        2.06      96.61%
Mwendamboko    NMTTR-01  Transitional   4.33      98.61%
Mwendamboko    NMTTR-02  Transitional   3.30      97.59%
Namoya Summit  NMTOX-05    Oxide        2.39      95.82%
Namoya Summit  NMTOX-06    Oxide        4.52      97.57%
Kakula         NMTOX-07    Oxide       10.45      99.61%
Kakula         NMTOX-08    Oxide        2.76      98.01%
Kakula         NMTTR-03  Transitional   3.57      97.48%
Kakula         NMTTR-04  Transitional   3.00      96.35%

The composite samples, which were approximately 10 kilograms each, consisted of representative oxide and transitional mineralization from the three main deposits at Namoya: Mwendamboko, Kakula and Namoya Summit. The oxides extend from 0 to 182 metres below surface (averaging 114 metres below surface) whilst the transitional material extends from 60 to 228 metres below surface (averaging 189 metres below surface).

Commenting on these metallurgical results at Namoya, Peter Cowley, President and C.E.O. of the Company, said: “These initial results demonstrate the non-refractory nature of the oxide and transitional material at Namoya with excellent metallurgical recoveries using standard, conventional processing. Due to the deep weathering profile at Namoya with oxides over 100 metres below surface and the transitional material averaging 189 metres below surface, the final open pits should consist predominantly of this softer, oxide and transitional material which should result in reduced mining and processing costs.”

Samples were sent to SGS Lakefield’s laboratory (which is independent of the Company) in Johannesburg, South Africa. Preparation involved the air-drying of the “as received” material. The individual samples were then crushed to 100% passing -1.7mm before being milled to 80% passing -75µm. The milled material was blended and split into representative sub-samples for the testwork. The testwork procedure involved the sequential solubilizing of the least-stable minerals via various pre-treatments, and extraction of the associated gold by cyanidation/CIL. To quantify the gold that can be extracted via direct cyanidation, samples were cyanided. To quantify the gold that is preg-robbed, but is recoverable via CIL processing, a second sample was cyanided in the presence of activated carbon. The duration of the leaching was 24 hours.

Skead (who is the Company’s Vice President of Exploration) dated March 30, 2006, and entitled “NI 43-101 Technical Report, Namoya Project, Maniema Province, Democratic Republic of the Congo.” A copy of this report can be obtained from SEDAR at www.sedar.com.

Banro is a Canadian-based gold exploration company focused on the development of four major, wholly-owned gold projects along the 210 kilometre-long Twangiza-Namoya gold belt in the South Kivu and Maniema provinces of the DRC. Led by a proven management team with extensive gold and African experience, Banro’s strategy is to unlock shareholder value by increasing and developing its significant gold assets in a socially and environmentally responsible manner.

Such forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause actual events or results to differ materially from estimated or anticipated events or results implied or expressed in such forward-looking statements. Factors that could cause such differences include gold recoveries for Namoya being less than those indicated by the Metallurgical Results (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), changes in world gold markets and equity markets, political developments in the DRC, changes to regulations affecting the Company’s activities, uncertainties relating to the availability and costs of financing needed in the future, the uncertainties involved in interpreting drilling results and other ecological data and the other risks involved in the gold exploration and development industry.
