Banro Corporation: On Track to Full Production in Q1 2012

- Start-up phase production approximately 2,800 ounces to date
- Expect steady state production of 120,000 ounces/year
- Mine construction at Namoya scheduled to begin Q1 2012

TORONTO, ONTARIO -- (Marketwire) -- 12/21/11 -- Banro Corporation ('Banro' or the 'Company') (NYSE Amex: BAA)(TSX: BAA) is pleased to provide an update on its wholly-owned Twangiza oxide gold mine in South Kivu Province, Democratic Republic of the Congo (the 'DRC'), which is in the process of ramping up to full production in the first quarter of 2012, as originally scheduled.

Following Twangiza's first gold pour in October 2011, the mine and plant continue to gear up to full commercial production. The addition of two CIL (carbon in leach) tanks in the second half of 2012 will bring the mill to full capacity, increasing throughput from the start-up rate of 1.3 million tons per year to the steady-state of 1.7 million tons per year. Once at steady state, estimated production of 120,000 ounces per annum is forecast. The gold export process has now commenced successfully with gold being transported in accordance with in-country protocols from Twangiza to Rand Refinery in South Africa.

Of the US$209 million budgeted for capital expenditure for the construction of the Twangiza oxide mine, which included a US$13.5 million contingency, US$191 million had been spent to the end of the third quarter of 2011. The balance of funds will be used to complete the commissioning. The Company's current cash position is sufficient to underpin the Company's working capital and overheads until such time that the Company moves into a positive free cash-flow position, which is expected within the first quarter of 2012.

'At this point, approximately two months into our commissioning and moving towards full commercial production, Banro has navigated its way through much of the operating risks of bringing a new gold mine on stream,' commented CEO Simon Village. 'We have experienced many of the normal challenges in commissioning and fine tuning a plant, and I am pleased to say have now largely been overcome, which demonstrates the capabilities of our management and staff in building out the Twangiza mine and the next project, Namoya.'

As per Banro's oxide strategy, cash-flow from the Twangiza oxide mine will be used to fast-track the second mine development project at Namoya, at the southern end of the Twangiza-Namoya gold belt. Start-up of a second gold mine within the next 18 months can provide the Company with greater overall flexibility and cash flow sooner for the potential development of other oxide projects at Lugushwa and Kamituga, also along this 210 kilometre long gold belt.


Qualified Person

Gary Chapman, the Company's Vice President, Operations and a 'qualified person' (as such term is defined in National Instrument 43-101), has reviewed and approved the technical information in this press release.

Banro Corporation is a Canadian gold mining company focused on production from the Twangiza oxide mine and development of four additional 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 Democratic Republic of the Congo. Led by a proven management team with extensive gold and African experience, Banro's plans include the construction of its second gold mine at Namoya, at the south end of this gold belt, as well as the development of two other projects, Lugushwa and Kamituga, in the central portion of the belt and a second project at Twangiza to mine the sulphide portion of the resource. Banro's strategy is to unlock shareholder value by increasing and developing its significant gold assets in a socially and environmentally responsible manner.
