Drilling Update at Akie Property


August 15, 2007
Vancouver , B.C. – August 15, 2007 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: A0F7E1 (“Mantle” or the “Company”) is pleased to provide an update on the 2007 drill program at its Akie property in northeastern British Columbia .  The program commenced with one drill rig on June 23, and since that time two additional machines have been brought on line. All three drill rigs are in operation and are positioned to further test the Cardiac Creek Zone (CCZ). This work is being carried out by Rodren Drilling Ltd. of West St. Paul , Manitoba .
 
Three holes have been completed on the CCZ for a total of 1,925.74 meters and all have intersected the zinc-lead mineralized horizon. The first hole (A-07-42) was designed to probe the extension, for a distance of some 200 meters to the north, of the high grade mineralization encountered in an earlier hole (A-05-32/2005) which yielded a true width (TW) of 8.44 meters grading 16.16% zinc and 3.95% lead. The other two holes (A-07-43 and A-07-45) were drilled from a new pad, located some 500 meters to the south, to test the continuity of this high grade mineralization between two earlier holes (A-05-30 and A-05-33/both 2005). In addition to these three holes, one hole has been completed, to a depth of 221.28 meters, in the South Zinc Anomaly and core from this is currently being logged.
 
At present, one rig, currently at 155 meters, is tasked to drill a second step-out hole, collared some 200 meters to the north of hole A-07-42, with the objective of further extending the high grade mineralization; the target depth is 650 to 675 meters. The remaining rigs are engaged in drilling in-fill holes up-dip (approximately 85 meters) from the mineralized intercepts encountered in two earlier holes (A-06-38 and A-06-39A/2006); target depths are 350 to 380 meters.
 
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 by 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.
