Akie Property – Work Progress Update
May 7, 2008
Vancouver, B.C. – May 7, 2008 – Mantle Resources Inc. (TSX Venture: MTS; Frankfurt: AOF7E1) (the “Company”) is pleased to provide a work progress update on its 100% owned Akie zinc-lead property within the Kechika Trough of northeastern British Columbia.
Access Road Construction Status
The logging of the extension of the Akie Main Line access road has now been completed to its planned terminus and to the commencement of the shorter drill access trails. A temporary road was established during this phase of work to accommodate logging, processing of timber and for the installation of temporary bridges. The total distance logged was of 8.7 kilometres, with work to date being completed on time and on budget. The one required permanent bridge was also installed during this phase of work. During demobilization, all temporary creek crossing structures were removed and drainage control features established as per ministry requirements and good operating practice. All phases of the work were monitored for environmental compliance. Participation of members from both Tsay Keh and Kwadacha First Nations communities was instrumental in providing local knowledge, input planning, implementation of the design and decommissioning.
The next phase of work is expected to commence once the spring thaw is complete and drier conditions prevail – anticipated to be within approximately one month’s time. Road construction will re-commence initially for the entire Akie Main Line, and thereafter for the access trails.
Upon completion, the impact of this new road will be very significant in carrying out the Company’s exploration plans for 2008 and beyond. The terminus of the main portion of the road is in the vicinity of where an exploration portal is envisioned. The ability to conduct detailed assessments of the area will be greatly facilitated by road access. In addition, much of the exploration drilling that is planned for later this year can be supported by road access. The new road is expected to reduce overall drilling costs and lead to increased productivity over an extended operating season. Further, road access will provide for safer operations for Mantle personnel and its contractors.
“We are very pleased with the progress made already this year on the Akie property, as this new access road will increase our ability to effectively explore the region. The completion of the access road will allow acceleration of our plans and substantially reduce the need for helicopter support of drilling on the Cardiac Creek Deposit. Once completed, this road will provide direct transport from site to the town of
for services and supplies and where access to the provincial highway network and Canadian National Rail system is available,” stated
, President of Mantle. “The completion of the access road is significant in that it connects the project to an extensive network of roads and will greatly enhance the potential to develop the Cardiac Creek deposit.”
About the Akie and Regional Properties in
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. In a press release dated April 16, 2008, the Company 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.
