Banro Corporation to be Added to the S&P/TSX Composite Index

- Effective Monday September 19, 2011

TORONTO, Sept. 15, 2011 /CNW/ - Banro Corporation ('Banro' or the 'Company') is pleased to announce that Banro will be added to the S&P/TSX Composite Index effective Monday September 19, 2011. This is a benchmark index for the Toronto Stock Exchange representing the Canadian Equity Market, with market capitalization and liquidity as the main criteria for inclusion. This index represents the 500 largest companies listed on the Toronto Stock Exchange.

'Banro's inclusion in the S&P/TSX Composite Index underlines the growth in market value established by the Company in the DRC, and development of the gold projects delineated to date along Twangiza-Namoya gold belt,' commented Simon Village President/CEO of Banro Corporation. 'Our strategy of identifying low cost, open pit, and high margin gold ounces and then taking these projects through the value curve from exploration, development and production, is a simple one and also a proven model for unlocking real value for our shareholders, and given our controlling position on one of Africa's last remaining but undeveloped gold belts is likely to continue.'

Banro Corporation is a Canadian-based gold exploration and development company focused on the development of four major, wholly-owned gold projects, each with mining licenses, 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 is constructing 'Phase 1' of its flagship Twangiza project. Banro's strategy is to unlock shareholder value by increasing and developing its significant gold assets in a socially and environmentally responsible manner.

Cautionary Note to U.S. Investors

The United States Securities and Exchange Commission (the 'SEC') permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Certain terms are used by the Company, such as 'measured', 'indicated', and 'inferred' 'resources', that the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC. U.S. Investors are urged to consider closely the disclosure in the Company's Form 40-F Registration Statement, File # 001-32399, which may be secured from the Company, or from the SEC's website at http://www.sec.gov/edgar.shtml.
