ASSAY RESULTS FOR HOLE: A-07-45
32.02 METERS GRADING 15.35 % ZINC, 3.40 % LEAD, 25.24 g/t SILVER
FROM 100% OWNED AKIE PROPERTY, B.C.
Vancouver, B.C., Canada � Wednesday, November 7, 2007 � Mantle Resources
Inc. (TSX Venture: MTS; Frankfurt: AOF7E1) (the
�Company�) is pleased to report the following assay results for hole A-07-45,
the third hole completed this year on the Cardiac Creek Zone (CCZ)
mineralization on its 100% owned Akie zinc-lead property, in northeastern
British Columbia, approximately 260 kilometers north-northwest of the town of
Mackenzie.
Hole:
A-07-45. (Az: 040o;
Dip: -78o; Grid: 3385S/0105W; Elev: 1429 meters; End of hole:
584.01 meters)

These
compiled assay values have been derived from analytical data provided by Acme
Analytical Laboratories Ltd., Vancouver, B.C. (Acme). The true width (TW) of
the mineralization is estimated to be approximately 70% of the core interval,
but this is subject to revision.
A-07-45 was
drilled from the same collar location as A-07-43 and A-94-12 (completed by
Inmet Mining Corporation in 1994). Hole 45 penetrated
the CCZ some 45 meters
updip from a similar intercept as reported in hole 43. The table below
summarizes the results to date for the three holes for which assays are now
available, including today�s results.

note:
* denotes holes previously released
These
results indicate that the CCZ mineralization is centred on a higher grade long
axis of at least 700
meters in length. This high grade �core� remains open
both up and down dip as well as down plunge to the southeast and northwest �
areas of significant primary exploration potential.
�This, our
third hole completed this year, represents grades and thicknesses within a
higher grade corridor of the CCZ and provides excellent exploration
guidance to additional areas of similar widths and grade on the Akie property.
The wide higher grade section of 22.59% Zn+Pb clearly enhances the zone in
terms of contained metal. As the CCZ remains open both on strike and down
plunge, I believe our Akie property hosts one the best
base metal targets currently being explored anywhere in Canada� stated
Jim Mustard, President of Mantle.
Access Road Status
Mantle has
recently submitted an application to various authorities within the BC
provincial government for an extension of the Akie forestry logging road. The
length of the road is estimated at 16 kilometres and
follows a planned route previously designed by the logging company in the
district. This road, if approved, will provide surface access to the CCZ area
to facilitate a planned expansion of drilling in 2008 and additional site
activities to fully explore the property as the Company foresees an expanded
exploration program in 2008. Commencement of road work will depend on timing of
approvals, but the Company is hopeful its application will be approved before
year end.
Assay Samples and Procedures
All core
selected for analysis is split by diamond saw and sampled, with a maximum of 1.5 meters of core in
each sample. These are placed in plastic bags, shipped in secure containers to
Acme Analytical Laboratories Ltd., Vancouver, B.C., and there subjected to aqua
regia digestion followed by ICP-ES and ICP-MS analysis (Acme Group 7AX
Multi-Element Assay) to determine zinc, lead and silver content. Standards and
blanks are inserted into the assay stream at a rate of about one of each for
every 25 core samples. Check assays are regularly carried out by Global
Discovery Labs, also in Vancouver,
employing aqua regia digestion followed by atomic absorption finish (Group 4).
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 and this year has identified a significant body
of baritic SEDEX mineralization (Cardiac Creek Zone). 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 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 averaging approximately 10% combined zinc+lead.
