Banro Intersects 16.60 metres grading 8.03 g/t Au and 47 metres grading 2.38 g/t Au in Pre-Feasibility Drilling at Twangiza Gold Project
Other drill intersections include, 27.00 metres grading 3.68 g/t Au, 24.70 metres grading 3.72 g/t Au and 15.90 metres grading 6.84 g/t Au
Toronto, Canada — May 29, 2008 - Banro Corporation (“Banro” or the “Company”) (AMEX - “BAA”; TSX - “BAA”) is pleased to announce final results from the Company’s 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 28 core holes drilled at the Twangiza North and Twangiza Main deposits since the last drilling update in April 2008.
Hole TDD194 intersected 16.00 metres grading 5.19 g/t Au from 0.00 metres Hole TDD198 intersected 15.90 metres grading 6.84 g/t Au from 49.00 metres Hole TDD200 intersected 27.00 metres grading 3.68 g/t Au from 86.00 metres Hole TDD203 intersected 24.70 metres grading 3.72 g/t Au from 9.30 metres Hole TDD203 intersected 16.60 metres grading 8.03 g/t Au from 75.00 metres Hole TDD208 intersected 19.00 metres grading 3.25 g/t Au from 86.00 metres Hole TDD212 intersected 16.40 metres grading 3.58 g/t Au from 166.60 metres Hole TDD217 intersected 47.00 metres grading 2.38 g/t Au from 0.00 metres These results complete the pre-feasibility drilling undertaken at Twangiza with the objective of upgrading the mineral resources into the Measured and Indicated Resource categories so that ore reserves can be determined as part of the pre-feasibility study which is due for completion in June 2008. The six drilling rigs currently operating at Twangiza have commenced infill drilling as part of the full feasibility study as well as commencing drilling on other new prospects on the Twangiza property.
At present, Twangiza 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). Reference is made to Banro’s press release dated January 15, 2008 (a copy of which can be obtained from SEDAR at www.sedar.com).
Commenting on these drilling results at Twangiza, Mike Prinsloo, President and C.E.O. of the Company, said: “These encouraging drilling results, which include significant intersections at shallow depth, complete the pre-feasibility drilling at Twangiza and will be incorporated into a revised mineral resource calculation and used to determine ore reserves as part of the pre-feasibility study. Our focus will now be on-infill drilling as part of the full feasibility study as well as on commencing initial drilling on other promising prospects, such as Mufwa and Luhindja, which have been delineated in close proximity to the existing Twangiza Main and Twangiza North deposits.”
A locality plan of the reported drill holes is found accompanying this press release on the Company’s web site at http://www.banro.com/i/pdf/2008-05-29_NRM.pdf.
Results from the core holes are tabulated in the following table:

Core holes were inclined at between minus 50 and 73 degrees and averaged 205.78 metres in depth with a maximum down hole depth of 525.00 metres. Core recovery for these holes averaged 90.4% 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 low grade, pelitic metasediments 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, which adhere to internationally recognised standards, duplicates and blanks were inserted into the sample batches.

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 http://www.sec.gov/edgar.shtml.

Factors that could cause actual results or events to differ materially from current expectations include, among other things, failure to establish estimated mineral resources (the mineral resource figures referred to in this press release are estimates and no assurances can be given that the indicated levels of gold will be produced), the possibility that future exploration results will not be consistent with the Company’s expectations, gold recoveries for Twangiza being less than those indicated by the metallurgical testwork carried out to date (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, fluctuations in currency exchange rates, inflation, 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 geological data and the other risks disclosed under the heading “Risk Factors” and elsewhere in the Company’s annual information form dated March 28, 2008 filed on SEDAR at www.sedar.com.
