Mantle Resources Inc.: 2006 Akie Drilling Program to Commence

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 15, 2006) - Mantle Resources Inc. (TSX VENTURE:MTS)(FWB:AOF7E1) ("Mantle") is pleased to announce that the 2006 drill program will commence this week at its Akie zinc-lead property located in northeastern British Columbia, approximately 280 kilometers north-northwest of the town of Mackenzie.

The initial phase of the 2006 exploration program is budgeted at approximately $3 million. The majority of the expenditures will be for drilling, however $100,000 has been allotted for metallurgical studies of drill core and $30,000 for drill access road location GPS survey and plotting. The Company anticipates drilling between 9 and 12 holes in this initial phase of the 2006 work program.

The goal of this phase of drilling will be to outline a potentially economic 12-15 million tonne zinc-lead deposit grading 12%-15% zinc-lead which could sustain a 3,000 tonne/day mine for 12 to 15 years.

The metallurgical work will be conducted at the Lakefield lab in Peterborough, Ontario, and will entail flotation and sink-float studies of the drill cores designed to ascertain feasible processes and flow sheets for extracting the zinc and lead from the ore.

Coast Mountain Geological Services Ltd., of Vancouver, B.C., has once again been retained to provide camp management and logistical support services for the exploration program. Mobilization of drill equipment and operating personnel to the property is currently taking place.

"With the snow conditions having now eased up, we are very excited to be able to re-commence exploration of the Akie zinc-lead property," said Peeyush Varshney, president of Mantle Resources. "With the very encouraging assay results obtained from the three drill holes in late 2005, we look forward to continuing to prove up an economic tonnage of higher grade zinc-lead mineralization at the main Akie deposit. As the Akie deposit is open to expansion in tonnage and grade both along strike and down dip, we feel that there is significant potential to further increase the size of the deposit. Future exploration programs will also focus on discovering other bodies of potentially economic mineralization on the property."

In late 2005 three diamond drill holes were successfully completed by Mantle on the Akie sedex zinc-lead deposit. Below is a compiled table of assay results for the three 2005 diamond drill holes (A-2005-30, A-2005-32 & A-2005-33) that were previously reported in news releases dated November 23, 2005, December 21, 2005 and January 16, 2006:

For each of the zinc, lead and silver values presented above, the first figure has been derived from assay data from Acme Analytical Laboratories Ltd. ("Acme"), Vancouver, B.C., and the second, in brackets, has been calculated from confirmatory assays carried out on assay pulps from Acme by Global Discovery Labs, Vancouver, B.C. The silver assays were not checked. The true width of the mineralization reported above is estimated to be 72% of the core interval and is subject to revision.

The relative locations of these three drill holes strongly suggest the discovery of a sizable high-grade slab of zinc-lead mineralization which is continuous over a quarter-mile (400-metre) strike length and open in all directions.

This high grade zone is part of the Akie pyrite-sphalerite-barite-galena sedex deposit previously discovered in 1995 through very widespaced drilling by Inmet Mining Corporation.

Assay Samples and Assay Procedures:

All mineralized core will be split by diamond saw and sampled, with a maximum of 1.5 meters of core collected for each sample. These samples will be bagged and shipped in secure containers to Acme Analytical Laboratories Ltd. in Vancouver for analysis for zinc, lead and silver by aqua regia digestion followed by ICP analysis (Group 7A-ICP Multi-Element Assay).

Qualified Persons: John R. Fraser, PGeo (B.C.) is the Qualified Person for Mantle and is responsible for the technical information contained in this release.

About the Akie Property:

The Akie property, which has been optioned from Ecstall Mining Corporation, comprises a total of 256 claim units, in 22 contiguous mineral claims encompassing some 5,400 hectares, situated in the Omineca Mining Division of British Columbia. Between 1992 and 1996, approximately $5.4-million was spent exploring the property, including approximately 13,000 metres of diamond drilling.

Variably siliceous, bluish-grey weathering, fine-grained clastic rocks of the Middle to Late Devonian 'Gunsteel formation' host a sheet-like body of laminated to massive pyrite and barite, with local finely laminated bands of sphalerite and galena, that has a strike length of 1,600 meters, a dip extent of at least 800 meters and a true width of up to 30 meters. Within this, Inmet Mining Corporation, the previous operator, identified an inferred resource, based on four widely spaced drill holes, of 13 million tonnes grading 8.52% zinc, 1.47% lead and 13.24 grams silver/tonne over a true width of 6.3 meters.

Note: This historical inferred resource estimate was prepared before the implementation of National Instrument 43-101. The Company's Qualified Person has not reviewed the estimate but believes it to be reliable and relevant as it was calculated by Inmet Mining Corporation, a respected international mining concern, using simple polygonal blocks. However, this estimate should be treated as a historical resource estimate and should not be relied upon until additional drill hole information is available.

Photos of the Akie zinc-lead property are available at the Company's website at www.mantleresources.com.
