Mano Discovers First Kimberlite in a New Area of Sierra Leone

No: 2006/16

• First known kimberlite dyke discovered in south eastern Sierra Leone

• Ground geophysical surveys underway to identify additional kimberlites

Mano River Resources Inc (“Mano” or “the Company”) is pleased to announce that it has discovered the first known kimberlite dyke in south eastern Sierra Leone.

The kimberlite is the first to be discovered in the 9,700km2 Reconnaissance Exclusive Prospecting Licence (“REPL”) that is held under joint venture with BHP Billiton. It is located in the southeast of the REPL and was discovered through trenching over positive kimberlite indicator minerals, including abundant G10 garnets. Preliminary indications are that the kimberlite is a 1.8m wide dyke that could extend over a potential distance of two kilometres on the basis of the indicator mineral distribution.

Ground electro-magnetic surveys are being conducted to investigate whether kimberlite pipes or blows exist in the vicinity of this new occurrence. The dispersion of the indicator minerals suggests the presence of additional kimberlites in the area and thus it is possible that a new kimberlite cluster for Sierra Leone has been identified.

Elsewhere in the REPL, follow up work continues in four separate areas where indicator mineral anomalies have been identified. BHP Billiton is funding the exploration programme and can earn a 51% equity interest in the licence once expenditure of $3.4million has been achieved. Expenditure to date exceeds $1 million. The partners will shortly be applying to the Government for exploration licences over ‘core’ target areas, relinquishing the balance of the ground as envisaged under the terms of the two-year reconnaissance licence.

Mano’s VP Diamonds, Karl Smithson comments: “The discovery of a kimberlite dyke in a new area of Sierra Leone is encouraging. With our partner, we are advancing follow up work in the area in the hope of finding additional kimberlites. We are also hopeful of making discoveries elsewhere in the REPL on the basis of our exploration results to date.”

About Mano River Resources

Mano is an exploration and development company focused on the discovery of diamond, gold and iron ore deposits in the Archaean terrain of the highly prospective, under-explored, West African Mano River Union countries of Sierra Leone, Liberia, and Guinea. The Company has a bankable feasibility study underway on what it is hoped will become Liberia’s first major gold mine, while in Sierra Leone joint venture partner Petra is already producing diamonds as it explores the Kono kimberlite dykes. The Company presently has some 25,000km2 under mineral licence and joint ventures in place with BHP-Billiton, Golden Star Resources, Navasota, Petra Diamonds, Searchgold and Trans Hex Group. In eastern Liberia, reconnaissance work is under way on Mano’s Putu iron ore project, with Fe assays due shortly on the latest batch of samples from this 8km long deposit.
