Banro identifies new gold mineralization zones at its Namoya project
TORONTO, June 24 /PRNewswire-FirstCall/ - Banro Corporation ("Banro" or the "Company") (NYSE AMEX - "BAA"; TSX - "BAA") is pleased to report that surface exploration work has identified two new gold mineralization zones at the Namoya Summit prospect at the Company's wholly-owned Namoya project, located on the Twangiza-Namoya gold belt in the Democratic Republic of the Congo (the "DRC"). The on-going exploration work at the Namoya Summit prospect includes geological mapping, channel sampling of exposures and trenching. The goal of the current exploration program is to delineate additional, near-surface resources that are within economic hauling distances of the proposed Namoya mine.
Highlights
- The two new gold mineralization zones are located to the southwest
and northwest of the Namoya Summit deposit. Exploration work has so
far covered a strike length of 250 metres at the southwest zone and
200 metres at the northwest zone.
- Trench sampling results from the southwest mineralization include
4 metres grading 2.73 g/t Au, 10 metres at 8.24 g/t Au and 3 metres
at 5.29 g/t Au.
- Channel sampling results of the southwest mineralization include
17 metres grading 6.90 g/t Au, 9 metres at 5.69 g/t Au, 6 metres at
6.57 g/t Au, 8 metres at 3.90 g/t Au, 8 metres at 4.21 g/t Au and
8 metres at 2.89 g/t Au.
- Trench sampling results of the northwest mineralization include
5 metres at 3.11 g/t Au, 12 metres at 5.12 g/t Au and 6 metres at
8.93 g/t Au.
Locality plans of the Namoya Summit Prospect can be found on the Company's website at http://www.banro.com/i/pdf/2010-06-24_NRM.pdf.

The trenches and channels at the southwest zone are generally oriented northeast - southwest and are spaced between 7 metres and 45 metres apart over a strike length of 250 metres. The gold mineralization is associated with quartz veins and stockworks which generally trend northwest - southeast and dip shallowly to the northeast. The mineralization appears to represent a northwest trending mineralized stockwork with a width which exceeds 10 metres in places.
The exploration work on the southwest mineralization of the Namoya Summit prospect is being continued by auger drilling in order to test bedrock in places that could not be accessed by trenching and channeling due to the steepness of the terrain.
Northwest Namoya Summit Zone
----------------------------
An auger drilling program was conducted on the northwest portion of Namoya Summit with the goal of testing the strike continuity of the mineralized zones. Some significant auger results are presented in the table below.

Three NE-SW trending trenches with a total length of 151 metres were excavated at a spacing of 40 metres (in between the auger fences) on the northwest portion of Namoya Summit with the aim of defining more confidently the mineralized zones and obtaining additional structural data. Significant results from these trenches are tabulated below.

The Company plans to follow up on the results of the surface exploration work at the Namoya project with a diamond drilling program in the third quarter of 2010.
The trench and channel sampling for both zones were undertaken at approximately one metre intervals and the above assay composites are uncut. The samples were placed in sealed bags by Company geologists and sent to the Company's sample preparation facility in Bukavu, DRC. The samples were then crushed down to minus 2 mm, split with half the sample then being 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. Internationally recognized standards, duplicates and blanks were inserted into the sample batches as part of the Company's QA/QC analytical procedures.
In March 2009, Banro's independent geological consultant, SRK Consulting (UK) Ltd. estimated the Namoya Mineral Resource as follows:

Reported at a 0.4g/t Au Cut-off Grade.
The Company believes that the positive exploration results discussed in this press release have the potential to add significantly to the Namoya Resource, enhance project economics and improve the likelihood of Namoya being Banro's next project for development following completion of the Company's Twangiza Phase I gold mine in 2011. To that end, the Company is completing a Feasibility Study of Namoya, which includes a comparative analysis of building a carbon-in-leach (CIL) versus a heap leach plant. Discussions are also underway with various parties to construct an access road from the main N2 Road to the proposed Namoya plant site.
