METERS GRADING 11.41% ZINC, 2.24% LEAD,15.36 g/t SILVER
FROM 100% OWNED AKIE PROPERTY, B.C.
Vancouver, B.C. �January 7, 2008 � Mantle Resources Inc. (TSX Venture:
MTS; Frankfurt: AOF7E1) (the �Company�) is pleased to report
the following assay results for hole A-07-49, the seventh hole completed in
2007 on the zinc-lead bearing Cardiac Creek Zone (CCZ) mineralization at its
100% owned Akie property, in northeastern British Columbia, approximately 260 kilometers
north-northwest of the town of Mackenzie.
Significant
Expansion of the CCZ � intercept delivers 13.65% Zn+Pb over 20.19 metres
Hole:
A-07-49. (Az: 060o; Dip: -64o;
Grid: 3135S/0075W; Elev: 1424
meters; End of hole:387.71 meters)

The true
width of the mineralization is estimated to be approximately 78% of the core
interval, but is subject to revision.
The
intercept in hole A-07-49 is located approximately 170
meters updip
from the high-grade mineralization encountered in hole A-05-30 (34.05 meters grading
11.87% zinc and 2.83% lead) and represents a significant expansion of the CCZ.
At present, the CCZ continues to be open updip, and to the north and south
along strike, from this hole.

the 2007 drilling program are summarized below.

notes: * denotes holes previously released
** this recompiled interval is for a wider zone than
that reported on Nov 7
�We are very
pleased by the high grades encountered in hole A-07-49, given that it is
located a considerable distance updip (170 metres) from hole
A-05-30, which also returned a wide intercept of high-grade zinc+lead. Clearly,
this confirms that the CCZ mineralization remains open towards the surface in
this area. The previous wide spaced drilling up to 600 metres apart on
strike (conducted by Inmet) indicates there is significant geological potential
for additional expansion beyond that defined to date by our own drilling,�
commented Jim Mustard, President of
Mantle.
Assay
results have also been received for hole A-07-46, an exploratory scout hole
collared some 250 meters
northwest of A-07-42 (the nearest hole) designed to test the continuation of
the CCZ to the northwest. Two mineralized horizons were encountered, an upper
and lower, separated by approximately 14 meters, comprised of a wide lower grade
section, followed by a higher grade interval. A similar situation is observed
in other holes located in this northerly part of the zone drilled to date.
Hole:
A-07-46. (Az: 069o; Dip:-74o; Grid:
2645S/0205W; Elev: 1720

�Although
hole A-07-46 may have been drilled updip of the targeted mineralization, it is
highly significant that we are still encountering mineralization far to the
northwest (A-07-46 is approximately 500 metres northwest of hole A-07-49). We
believe the CCZ continues to be open downdip and to the north along strike in
this area,� stated Mr. Mustard.
�With the
CCZ demonstrating substantive further exploration potential and with our
commanding land position in the Kechika district, Mantle is well positioned for
an exciting 2008 exploration season. We are well advanced in the planning for
our 2008 program and expect to provide a scope of work in the coming weeks.�
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, 2006 and 2007 has identified a significant body of
baritic-zinc-lead 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.
