Banro intercepts 192 metres grading 2.02 g/t Au, 149 metres grading 1.71 g/t Au, 68 metres grading 3.77 g/t Au, 77.8 metres grading 2.17 g/t Au and 60 metres grading 3.50 g/t Au as part of the bankable feasibility drilling program at its Twangiza project

July 31st, 2008

Toronto, Canada — July 31, 2008 - Banro Corporation (“Banro” or the “Company”) (AMEX - “BAA”; TSX - “BAA”) is pleased to announce further results from the Company’s ongoing in-fill core drilling program at its wholly-owned Twangiza gold 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 30 core holes drilled at the Twangiza North and Twangiza Main deposits since the last drilling update in May 2008. These 30 core holes, which were drilled as part of the Company’s bankable feasibility study, were not included in the mineral resource estimates for the Twangiza pre-feasibility study announced on July 7, 2008.

Highlights include:

Hole TDD220 intersected 45.00 metres grading 4.26 g/t Au from 85.00 metres and 48.60 metres grading 1.84 g/t Au from 164.40 metres Hole TDD221 intersected 149.00 metres grading 1.71 g/t Au from 110 metres and 60.00 metres grading 3.50 g/t Au from 266.00 metres Hole TDD225 intersected 192.00 metres grading 2.02 g/t Au from 88.00 metres Hole TDD226 intersected 77.80 metres grading 2.17 g/t Au from 23.20 metres and 65.70 metres grading 2.90 g/t Au from 235.00 metres Hole TDD227 intersected 68.00 metres grading 3.77 g/t Au from 76.00 metres Hole TDD229 intersected 43.00 metres grading 2.42 g/t Au from 237.00 metres and 47.63 metres grading 2.35 g/t Au from 294.00 metres Hole TDD234 intersected 34.6 metres grading 3.19 g/t Au from 131.40 metres Hole TDD235 intersected 33.00 metres grading 2.76 g/t Au from 70.00 metres Hole TDD236 intersected 48.71 metres grading 2.53 g/t Au from 93.00 metres The objective of the current drilling program at Twangiza is to upgrade mineral resources into the Measured and Indicated Resource categories with the goal of determining ore reserves as part of the bankable feasibility study which is due for completion in December 2008.

Twangiza currently has an estimated Measured Mineral Resource of 1,390,000 ounces of gold (16,700,000 tonnes grading 2.59 g/t Au), Indicated Mineral Resource of 2,350,000 ounces of gold (42,500,000 tonnes grading 1.72 g/t Au) and Inferred Mineral Resource of 600,000 ounces of gold (10,000,000 tonnes grading 1.80 g/t Au). Reference is made to Banro’s press release dated July 7, 2008 (a copy of which can be obtained from SEDAR at

Commenting on the drilling results at Twangiza, Mike Prinsloo, President and C.E.O. of the Company, said: “These drill intercepts are significant in terms of grade and thickness and are in areas where Inferred Resources and unclassified material were previously demarcated within the pit shells as part of the pre-feasibility study announced earlier this month. These drilling results should contribute to an increase in Measured and Indicated Resources at Twangiza, as well as to an increase in the Proven and Probable Reserves to be incorporated in the bankable feasibility study for Twangiza.”

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

Holes are uncut.

Core holes were inclined at between minus 50 and 83 degrees and averaged 248 metres in depth with a maximum down-hole depth of 542.76 metres. Core recovery for these holes averaged 92.7% 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 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.

Additional information with respect to the Twangiza project is contained in the technical report of SENET dated September 13, 2007 and entitled “Preliminary Assessment NI 43-101 Technical Report, Twangiza Gold Project, South Kivu Province, Democratic Republic of Congo”.

A National Instrument 43-101 technical report relating to the Twangiza pre-feasibility study is expected to be filed on SEDAR during the next two to three weeks.

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.
