Mano River Update on Diamond Joint Venture in Sierra Leone

Reconnaissance programme nearing completion
· Early identification of high interest anomalies
· Phase-2 Follow Up to commence in May 2005

Mano River Resources Inc. (“Mano” or “the Company”) is pleased to report a progress update on exploration results from its Sierra Leone diamond joint venture with BHP Billiton.

In early 2004 Mano secured exclusive diamond, gold and base metal rights over a 9,700km2 Regional Exclusive Prospecting Licence (“REPL”) in the South Eastern quadrant of Sierra Leone. In May 2004 Mano entered a Joint Venture agreement with BHP Billiton that entitles BHP Billiton to earn a 51% interest through funding of two phases of exploration at a cost of $3.4million over a three year period. BHP Billiton can increase its interest in the Joint Venture to 70% by completing, at its own cost, a feasibility study over one or more kimberlites considered to have economic potential.

Reconnaissance exploration commenced in July 2004, utilising six geological teams. The programme comprises stream sediment sampling throughout the licence area. By the end of March 2005 over 800 of a planned 1,000 heavy mineral stream samples had been collected.

These samples have been exported to South Africa for laboratory analysis and results are available for approximately 200 samples. The initial results are encouraging with a number of kimberlite indicator mineral anomalies being generated. One particular anomaly is comprised of super-abundant ilmenite with supporting garnet and chromite. The immediate area of this anomaly is now being exploited for diamond by local artisanal miners, marking a totally new artisanal mining occurrence in this region. The gravels being exploited are angular and samples of these gravels also yielded similar abundant kimberlite indicator mineral populations. The freshness of the indicators and the angularity of the gravels suggest that the source(s) of the indicators are proximal to the artisanal diamond workings.

Selections of the reconnaissance indicators have been probed and returned encouraging results, with many of the garnets being classified as G10 in affinity (Plot 1), and some of the chromites being classified as diamond inclusion types.

The results to date have justified the decision of the Joint Venture to progress to the Phase-2 work programme. This will commence over the new anomaly in May, once the reconnaissance sampling has been completed. The follow-up programme will comprise loam sampling and ground geophysics designed to identify potential kimberlite pipe-like targets for pitting or drilling. Once full reconnaissance results are available, a more comprehensive follow-up programme will be designed and initiated.

About Mano
Mano is a well-funded exploration company focused on the discovery of gold and diamond deposits in the Archaean terrain of the highly prospective, under-explored, West African Mano River Union (MRU) countries of Sierra Leone, Liberia and Guinea. Mano considers the region has the potential to develop into a world class gold and diamond-mining province. The Company has over 25,000km2 under licence, close to one million ounces of gold in resource, a cluster of diamondiferous kimberlite pipes and joint ventures in place with Golden Star, BHP Billiton, Trans Hex Group, Navasota and Crown Diamonds which, if they are all fully exercised, will involve a total of over US$16m in third party expenditure. With increasing market recognition of the recent positive evolution in the regional politics, Mano is starting to capitalise on its position as the pre-eminent gold and diamond explorer in the sub-region.
