Mano River Makes Kimberlite Discovery in Liberia

New kimberlite body discovered in its Mineral Cooperation Agreement (MCA)

• Likely source of the abundant G10 garnets recovered in sampling

• Detailed loam sampling block completed

• Ground magnetics and gravity surveys planned

Mano River Resources Inc. (“Mano”) is pleased to announce that it has discovered a new kimberlite in its MCA licence in western Liberia, just four months after commencing exploration in the area. The MCA, covering 15,000km2, is a contributory joint venture between the Government of Liberia (30%) and Mano (70%) and incorporates the rights to explore for diamonds, gold and base metals.

On April 5th 2005, Mano reported high interest garnet recoveries from a number of MCA reconnaissance samples and on the basis of these results commenced follow-up investigations. A detailed loam-sampling block was recently completed and early results from Mano’s laboratory in Monrovia identified one specific area of interest where abundant ilmenite and garnet had been recovered. Shallow pits dug over these sample sites intersected highly decomposed kimberlite at a depth of just over 1m.

Considering the sampling results in the context of the local geomorphology, it is considered likely that more than one kimberlite is present in the immediate vicinity, so Mano is in the process of extending the loam sample coverage. In addition, ground gravity and magnetic geophysical surveys will be undertaken in the near future in an effort to fast-track future discoveries, as well as provide information on the surface area of the kimberlite(s). All kimberlites discovered will be analysed for diamond potential. However, based on the excellent garnet chemistry and the close proximity of artisanal diamond workings, Mano considers the diamond potential of this new kimberlite area to be high.

Mano’s President and CEO, Dr. Tom Elder, comments: “The early discovery of kimberlite in our MCA demonstrates Mano’s technical capability and justifies our belief that this part of the Archaean Man Craton is highly prospective for diamonds. The MCA extends over 15,000 square kilometres of this unexplored terrain and we have only scratched the surface in terms of its potential.”

Elsewhere in Liberia, Mano is currently embarking on detailed ground geophysical surveys over its diamondiferous kimberlite cluster at Weasua, in joint venture with Trans Hex Group. In addition, in Sierra Leone Mano is pursuing anomalous reconnaissance results in its 9,000 square kilometre REPL licence in partnership with BHP Billiton, while in the Kono area preparations have commenced for underground bulk sampling of Mano’s high-grade diamond-bearing kimberlite dykes, in partnership with Crown Diamonds.

About Mano
Mano is a well-funded exploration company focused on the discovery of diamond and gold deposits in the Archaean terrain of the highly prospective, under-explored, West African Mano River Union countries of Liberia, Sierra Leone, and Guinea. Mano considers the region has the potential to develop into a world-class diamond and gold-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 in Liberia and joint ventures in place with BHP Billiton, Trans Hex Group, Crown (Petra) Diamonds, Golden Star and Navasota, which, if they are all fully exercised, would see a total of over US$16m in third party expenditure on Mano’s properties. 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 diamond and gold explorer in the sub-region.
