MANTLE ANNOUNCES 2008 AFRIDI LAKE DRILL PROGRAM Ground Program Underway


March 26, 2008

Vancouver, B.C. – Wednesday March 26, 2008 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: AOF7E1) (the “Company”), Shear Minerals Ltd., International Samuel Exploration Corp. and New World Resource Corp. are please to announce the commencement of the 2008 exploration program at the Afridi Lake Diamond Project (“the Afridi Project”), Northwest Territories.  A minimum of 15 high priority geophysical targets will be drill tested.

An eleven person crew has been mobilized to the field with ground magnetic and gravity geophysical surveys underway.  Radius Drilling Corp. of Prince George , BC has been retained to complete the drilling and Quadra Surveys of Barriere, BC will complete all the ground gravity surveys.  All government land-use and industry road use permits are in place in anticipation of the upcoming drilling program. All operations are based out of Peregrine Diamonds DO-27 camp located 15km west of the Afridi Project.  It is anticipated drilling will commence in April with a budget of $1.2 Million.

“The airborne and ground gravity surveys that were completed in 2007 were a huge success,” commented Shear Minerals President and CEO Pamela Strand. “These methods clearly defined the known kimberlites as well as outlined a number of potential new targets that will be drill tested in the coming month.”

In 2007, a high resolution airborne gravity gradient survey was flown by Bell Geospace of Houston, Texas. It was proven that the density contrast between the surrounding rock and the known kimberlites was great enough to register an interpretable gravity gradient anomaly of two hectares or larger. A review of the geophysical data by independent consultant Christopher Campbell of Intrepid Geophysics, Vancouver , BC identified more than 25 targets characterized by land based isolated gravity low targets suggestive of kimberlite.

The Afridi Project is comprised of 56,000 acres of claims and mineral leases within the Lac de Gras Diamond District located 320 km northeast of the City of Yellowknife , NWT.  The Afridi Project adjoins both the DIAVIK Diamond Mine and the WO claims which host the DO-27 kimberlite. The Afridi Project is host to five known diamond bearing kimberlites and there are more than 40 known kimberlites within 40 kilometers of the Project. Shear Minerals Ltd. holds a 58.2% interest in the Afridi Project and is the operator. International Samuel has a 25.4% interest and New World Resource and Mantle Resources each hold 8.2%.

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