Results include soil values up to 1,880 ppb Au; rock chip samples grading up to 64.00 g/t Au; and channel samples in artisanal adits with intersections of 13.75 metres @ 8.75 g/t Au, 4.00 metres @ 24.15 g/t Au and 8.00m @ 7.87 g/t Au.




Toronto, Canada — June 6, 2008 - Banro Corporation (“Banro” or the “Company”) (AMEX - “BAA”; TSX - “BAA”) is pleased to announce the results of the first phase of exploration on the Mufwa Prospect, located in the Company’s wholly-owned Twangiza Project on the Twangiza-Namoya gold belt in the Democratic Republic of the Congo (the “DRC”). This work has included geological mapping, soil and rock chip sampling and channel sampling in adits developed by artisanal miners. Preparations are in progress for a preliminary core drilling program.

Three maps (Figures 1 to 3) highlighting the location and soil anomalies on the Mufwa Prospect are found accompanying this press release on the Company’s website at http://www.banro.com/i/pdf/2008-06-06_NRM.pdf.

The Mufwa Prospect (Figure 1) is located 11.5 kilometres northwest of the Twangiza Main and Twangiza North deposits where Banro has defined 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). The Company is currently in the process of completing a pre-feasibility study of the Twangiza Project.


Gold mineralization at Mufwa is hosted in weakly metamorphosed pelitic sediments which have been folded into a north-south trending anticline, with moderately dipping limbs and a northerly plunge of about 40°. The prospect is therefore similar to the Twangiza deposits in terms of structural setting. Gold mineralization is associated with several zones of quartz veining which are sub-parallel to bedding, and up to at least 14 metres in width. Within these zones, individual veins form irregular stockworks, sheeted vein systems and discontinuous lenses. Pyrite and arsenopyrite occur in the quartz veins in variable amounts, and may also occur disseminated in the host rock between the veins.

A soil sampling grid was established over an area measuring 4 kilometres by 2 kilometres, centred on the mineralization exposed by artisanal miners. Samples were taken at intervals of 40 metres on 80 metre-spaced lines, at a depth of 60 centimetres. A total of 2,500 soil samples were collected and analysed for gold. Using a threshold of 60 ppb Au, several anomalies are defined within an area measuring approximately 1,700 metres east-west and 700 metres north-south, indicating that mineralization extends outside the area of artisanal mining activity (Figure 2). Gold values of up to 1,880 ppb were returned for the soil samples.


Rock chip samples from outcrop confirm the presence of in situ gold mineralization in the vicinity of the soil anomaly, returning values of up to 64.00 g/t Au (Figure 2). (A total of 199 rock samples were collected and analyzed for gold).

Twenty-five adits (Figure 3) were mapped and channel sampled at approximately 1 metre intervals by hammer and chisel. (A total of 940 adit samples were collected and analyzed for gold). The most significant intersections were 13.75 metres grading 8.75 g/t Au, 4.00 metres @ 24.15 g/t Au, 8.00 metres @ 7.87 g/t Au, 5.00 metres @ 9.34 g/t Au, 9.90 metres @ 4.32 g/t Au and 11.00 metres @ 3.87 g/t Au.

Preparations are well advanced for an initial 10-hole, 2,000 metre core drilling program to further investigate the frequency, width, tenor and continuity of the mineralized zones at Mufwa.

Commenting on these results, Mike Prinsloo, President and C.E.O. of the Company, said: “These initial exploration results from our new Mufwa Prospect are very encouraging with the extent and structural setting similar to the Twangiza Main and Twangiza North deposits where we are finalizing the pre-feasibility study. We expect to commence initial drilling on this prospect towards the end of this month.”

All soil and rock samples were placed in sealed bags and sent to the Company’s sample preparation facility in Bukavu, DRC. The rock samples were then crushed down to minus 2 mm, and split with half of the sample pulverized down to 90% passing 75 microns. The soil samples were sieved to minus 2 mm, and the undersized fraction pulverized down to 90% passing 75 microns. Approximately 150 grams of the pulverized sample was then shipped to the SGS Laboratory (which is independent of the Company) in Mwanza, Tanzania where the samples were analyzed for gold by fire assay using a 50g charge. As part of the Company’s QA/QC procedures, which conform to 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.
