Akie Project - Exploration Update

July 26, 2007

Vancouver, B.C. – July 26, 2007 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: A0F7E1 (“Mantle” or the “Company”) is pleased to present a progress report on its exploration activities on the Akie zinc-lead property, and other properties in the immediate vicinity, located in northeastern British Columbia, approximately 260 kilometers north-northwest of the town of Mackenzie.

Diamond Drilling

The third of three drill rigs assigned to the Akie property has commenced drilling and is currently probing the “South Zinc” anomaly, located approximately 3 kilometers south-southeast of the Cardiac Creek Zone (CCZ), the primary target area on the Akie property.  This previously untested feature is defined by the +2,000 parts per million zinc-in-soil contour, is some 2 kilometers long by 200 to 500 meters wide, and encompasses samples that have also yielded anomalous lead values. The anomaly is underlain by folded ‘Gunsteel’ rocks that are proximal to the contact between the shales of the ‘Gunsteel’ formation and limestone, limestone breccia and siltstone of the Road River Group, which is identical to the stratigraphic location of the CCZ.

Two other rigs are currently employed on the CCZ to determine the extent and internal continuity of the high grade zinc-lead mineralization discovered in 2005.

  • The first is drilling a step-out hole (A-07-42), located some 200 meters to the north of hole A-05-32, which encountered a true width of 8.44 meters grading 16.16% zinc and 3.95% lead, and is presently at a depth of 501.70 meters (target: 670 meters).
  • A second rig is positioned approximately 600 meters to the south, between holes A-05-30 and A-05-33, both strongly mineralized, and has just completed the first (A-07-43) of two in-fill holes planned from this set-up, intersecting the CCZ at a down-hole depth of 535 meters. The next hole with this rig (A-07-45) is designed to pierce the CCZ approximately 80 meters updip from this point. Core from hole A-07-43 is currently being logged and sampled.

Rodren Drilling Ltd. of West St. Paul, Manitoba, is conducting the 2007 drill campaign which is expected to total approximately 15,000 meters.

Regional Exploration

Regional exploration activities, comprising prospecting, geologic mapping and sampling, recently commenced within the southern half of the 180 kilometer long package of Company controlled mineral holdings in the Kechika Trough. Initially, these efforts will be focused entirely on the extensive (18,198 hectares), highly prospective properties held under option from Megastar Development Corp. The Company can earn an initial 60% interest in these, all of which encompass shales of the ‘Gunsteel’ formation and a number of zinc-lead showings, by expending $2.25 million on exploration and development over a three year period.


The construction of a new camp site to replace the facility established in 2005 is now complete. Discussions and consultations with the Kwadacha and the Tsay Keh Dene First Nations, which were initiated in 2006, are ongoing. Environmental baseline studies related to permitting for road construction and establishing underground access for bulk sampling are presently in progress. Samples of mineralized drill core from holes completed in 2006 have been forwarded to SGS Mineral Services, Lakefield , Ontario , for metallurgical testing to expand upon that carried out in 2006.

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 Inmet Mining Corporation during the period 1994 to 1996 and Mantle in 2005 and 2006 has identified a significant body of baritic SEDEX mineralization (Cardiac Creek Zone) with an average thickness of greater than 12 meters and an average zinc+lead content in excess of 10%. 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 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.
