ASSAY RESULTS FOR HOLE: A-07-50
20.98
METERS GRADING 16.67% ZINC, 3.41% LEAD, 25.44 g/t SILVER
FROM 100% OWNED AKIE PROPERTY, B.C.
Vancouver, B.C. �January 21, 2008 � Mantle Resources Inc. (TSX Venture:
MTS; Frankfurt: AOF7E1) (the �Company�) is pleased to report
the following assay results for hole A-07-50, the sixth hole from the 2007
drill program 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.
High Grade
in A-07-50 � delivers 20.08% Zn+Pb over 20.98 metres within a 29.4 metre intercept
grading 15.78% Zn+Pb

The true
width of the mineralization is estimated to be approximately 76% of the core
interval, but is subject to revision.
The
intercept in hole A-07-50 is located between A-05-30 (23.83 metres grading
19.73% Zn+Pb) and A-05-32 (26.7 metres grading
14.69% Zn+Pb), which are 200 metres apart.� The thick intercept and high-grade
mineralization encountered in hole A-07-50, as reported
above, confirms an axis of higher grade that is consistent over an estimated
strike length of 700
metres and is open both to the northwest and
southeast.� At present, the CCZ continues
to be open both updip and downdip.
�Assays received to date from key holes from
the 2007 drilling program are summarized below.

����� notes: * denotes holes previously released
�We are very pleased by the high grades we continue to
encounter in the CCZ deposit.� As we are
now able to project the higher grade axis for some distance along strike, we
see significant potential in both the northwest and southeast direction,�
commented Jim Mustard, President of
Mantle.
�With the
CCZ consistently delivering these elevated grades, Mantle considers the Akie property to hold significant potential for additional
discoveries and sees the CCZ as a focus of intense work in the coming months.�
An
additional 5 holes have been submitted to the laboratory from the 2007 program
and results will be reported upon receipt.
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.
