Access Road Construction Commences Akie Property, B.C.


March 13, 2008

Vancouver, B.C. – Thursday March 13, 2008 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: AOF7E1) (the “Company”) is pleased to announce that, further to its news release dated November 28, 2007, construction of the access road to the Cardiac Creek deposit (“CC deposit”) on its 100% owned Akie zinc-lead property, in northeastern British Columbia, has commenced.

Access Road Permitting

Mantle submitted a Notice of Work application to the British Columbia Ministry of Mines and Petroleum Resources at the end of September and an approved Notice of Work and amended Mines Act permit was issued by the Ministry on November 20, 2007 for the construction of a new access road that will, in part, be an extension of the existing main line Akie forestry logging road. In addition, Mantle was issued an Occupant License to Cut from the Mackenzie office of the Ministry of Forests and Range for timber clearing of the right of way. The amended permits include approval for road construction, approval to complete up to 53,000 metres of drilling and necessary pad construction for drilling.

Access Road Design

The length of the main road extension is estimated at 9.0 kilometres and will be constructed to standard forestry codes. At approximately 8.7 kilometre distance, two shorter access trails are planned.

The planned route will provide road access to the CC deposit and will greatly facilitate the Company’s future exploration plans and additional site work. The new access road will reduce overall drilling costs, will increase the programs productivity and will facilitate essentially year round drilling. Importantly, road access will also provide for safer operations for both Mantle personnel and its contractors. Planning of the road involved several specialized disciplines including First Nations heritage studies and bio physical assessments. First Nations participation from both the Tsay Keh and Kwadacha communities was instrumental in providing local knowledge and advice to assist with planning and implementation.

Access Road Schedule

The work schedule will see the cutting of the right of way over the next several weeks followed by actual road bed construction after the spring thaw. Engineered stream crossing structures will be installed as required by permit and final road surfacing will be completed under dry conditions. The bulk of the road construction is anticipated to take place in August with completion expected in September.

“The new access road will allow us to considerably expand the amount of drilling we can complete in a season and it will provide us with significant flexibility in our future planning. It will lead to a more rapid exploration, assessment and development of the CC deposit,” stated Jim Mustard , President of Mantle. “We are pleased to demonstrate to the First Nations, the BC Government and to our shareholders our commitment to proceed with exploration in an environmentally and technically sound manner.”

About the Akie Property

The Akie zinc-lead property is situated within the southern-most part (Kechika Trough) of the regionally extensive Paleozoic Selwyn Basin, one of the most prolific sedimentary basins in the world for the occurrence of SEDEX zinc-lead-silver and stratiform barite deposits. 

Drilling on the Akie property by both Inmet Mining Corporation during the period 1994 to 1996 and by Mantle in 2005 and 2006 and this year has identified a significant body of baritic SEDEX mineralization (Cardiac Creek Zone). The deposit is hosted by variably siliceous, fine grained clastic rocks of the Middle to Late Devonian ‘Gunsteel Formation.

Two similar deposits, Cirque and South Cirque, located some 20 kilometers northwest of Akie and owned under a joint venture by Teck Cominco and Korea Zinc, are also hosted by Gunsteel rocks and have a combined geologic inventory in excess of 50 million tonnes averaging approximately 10% combined zinc+lead.
