Mantle Resources Inc. â€" Exhibiting at Cambridge House Investment Conference

Vancouver, B.C. – June 11, 2008 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: A0F7E1) (“Mantle” or the “Company) is pleased to announce that it will be exhibiting at Cambridge House International Inc.’s “2008 World Resource Investment Conference”, being held at the Vancouver Convention Centre on June 15 -16.

Mr. Jim Mustard , President of Mantle, extends an invitation to all attendees to visit Booth # 510.  The Company will be handing out information brochures as well as displaying some of the high grade drill core obtained from the exploration programs at the Company’s flagship Akie property.

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. The Company has recently announced an initial 43-101 compliant inferred resource estimate for the Cardiac Creek zinc-lead deposit on its 100-per-cent-owned Akie property.  At a zinc cut-off grade of 5 per cent, the deposit contains 3.95 billion pounds of zinc, 780 million pounds of lead and 8.95 million ounces of silver.

The deposit is hosted by variably siliceous, fine grained clastic rocks of the Middle to Late Devonian ‘Gunsteel’ formation which occur extensively on the Company’s claim holdings. 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. Mantle also owns an extensive Regional Property package (100% owned) which will be the focus of a district scale exploration program in 2008.

The TSX Venture Exchange has neither approved nor disapproved the contents of this press release.
