April 2nd, 2008

Drilling results include 108.50 metres grading 2.42 g/t Au, 70.60 metres grading 2.68 g/t Au, 30.89 metres grading 7.22 g/t Au, 44.00 metres grading 2.36 g/t Au, 30.00 metres grading 2.83 g/t Au and 13.59 metres grading 10.32 g/t Au

Toronto, Canada — April 2, 2008 - Banro Corporation (“Banro” or the “Company”) (AMEX - “BAA”; TSX - “BAA”) is pleased to announce further results from the Company’s ongoing pre-feasibility, core drilling program at its wholly-owned Twangiza project, located on the Twangiza-Namoya gold belt in the Democratic Republic of the Congo (the “DRC”).

Assay results have been received for an additional 58 core holes, which have been drilled at the Twangiza North and Twangiza Main deposits since the previous drilling update in September 2007.

Highlights include:
  • Hole TDD139 intersected 9.00 metres grading 10.71 g/t Au from 41.00 metres
  • Hole TDD150 intersected 30.89 metres grading 7.22 g/t Au from 49.49 metres
  • Hole TDD168 intersected 13.59 metres grading 10.32 g/t Au from 48.24 metres
  • Hole TDD182 intersected 70.60 metres grading 2.68 g/t Au from 0.00 metres
  • Hole TDD184 intersected 23.22 metres grading 3.67 g/t Au from 0.00 metres
  • Hole TDD187 intersected 44.00 metres grading 2.36 g/t Au from 0.00 metres
  • Hole TDD188 intersected 30.00 metres grading 2.83 g/t Au from 16.00 metres
  • Hole TDD189 intersected 108.50 metres grading 2.42 g/t Au from 0.00 metres
The current drilling program is part of the pre-feasibility study being undertaken at Twangiza with the objective of upgrading Inferred Mineral Resources into the Measured and Indicated categories, so that open pit ore reserves can be determined as part of the pre-feasibility study, which is due for completion in June 2008. To accomplish this, the Company has now increased the number of drill rigs operating at Twangiza to six.

Twangiza currently has an estimated Measured Mineral Resource of 1,315,000 ounces of gold (14,510,000 tonnes grading 2.82 g/t Au), Indicated Mineral Resource of 2,558,000 ounces of gold (39,119,000 tonnes grading 2.03 g/t Au) and Inferred Mineral Resource of 2,705,000 ounces of gold (46,188,000 tonnes grading 1.82 g/t Au). These Mineral Resources were determined using the assay results from drill holes TDD001 to TDD173. Reference is made to Banro’s press release dated January 15, 2008 (a copy of which can be obtained from SEDAR at

Commenting on these drilling results at Twangiza, Mike Prinsloo, President and C.E.O. of the Company, said: “These drilling results are encouraging with excellent conversion of Inferred Mineral Resources into the Measured and Indicated categories. The ongoing pre-feasibility study is proceeding well and we are on track for completion of this study by the end of June 2008. We are also making good progress on our other advanced gold project at Namoya, where the infill drilling program for the pre-feasibility study has been completed. The Namoya study is also due for completion in June 2008.”

Results from the core holes are tabulated in the following table:

Core holes were inclined at between minus 50 and 68 degrees and averaged 208.04 metres in depth with a maximum down hole depth of 464.08 metres. Core recovery for these holes averaged 81% within the mineralized zones. It is estimated that the true widths of the mineralized zones vary between 80% and 95% of the intersected widths in the holes. Drill hole spacing was on 40 metre sections.

The mineralized sections of the Twangiza North and Twangiza Main deposits are hosted within a series of mineralized feldspar porphyry sills and weakly metamorphosed pelitic sediments along a northerly trending anticlinal structure. The gold mineralization is associated with pyrite and arsenopyrite sulfides and silicic, carbonate and potassic alteration.

Drill cores for assaying were taken at a maximum of one metre intervals and were cut with a diamond saw with one-half of the core placed in sealed bags and sent to the Company’s sample preparation facility in Bukavu, DRC. The core samples were then crushed down to minus 2 mm, and split with half of the sample pulverised down to 90% passing 75 microns. Approximately 150 grams of the pulverised sample was then shipped to the SGS Laboratory (which is independent of the Company) in Mwanza, Tanzania where the samples were analysed for gold by fire assay using a 50g. charge. As part of the Company’s QA/QC procedures, internationally recognised standards, duplicates and blanks were inserted into the sample batches.

Banro is a Canadian-based gold exploration 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’s strategy is to unlock shareholder value by increasing and developing its significant gold assets in a socially and environmentally responsible manner.

Qualified Person

The exploration results disclosed by this press release have been reviewed, verified (including sampling, analytical and test data) and compiled by the Company’s geological staff based in Bukavu, DRC, under the supervision of Daniel K. Bansah, who is a Member of The Australasian Institute of Mining and Metallurgy (Aus.I.M.M), the Company’s Vice President, Exploration and a “qualified person” (as such term is defined in National Instrument 43-101).

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 No. 001-32399, which may be secured from the Company, or from the SEC’s website at
