A $1,600,000 diamond drilling program, comprising approximately 12,000
to 13,000 m of drilling in 16 to 20 holes and employing two drills,
commenced on the Deposit on December 1, 2010. The primary purpose of
this drill program is to increase the estimated mineral resources
outlined to date in the Deposit to the five to six million tonne range.
The potential increase of the current mineral resources is conceptual
in nature and it is uncertain whether further exploration drilling will
result in an expansion of this mineral resource.

The current drill program will focus on three main areas: 1) above the
-250 m elevation where historical drilling suggests that there is good
potential for outlining high grade resources above the area where
Cornerstone and Thundermin have focused their drilling to date and have
established a National Instrument 43-101 ("NI 43-101") compliant
resource for the Deposit (approx. above the 800 foot level drift from
the Whalesback Mine as shown on Figure 1); 2) along strike both east
and west of the limits of the currently outlined mineral  resource
between the -650 m and the -250 m elevations where the boundaries of
the Deposit have not been defined to date; and 3) at depth below the
-650 m elevation where a preliminary interpretation of the results from
borehole Pulse electromagnetic surveys suggest that there is potential
for the discovery of additional copper mineralization. The Deposit has
been outlined by drilling over a strike length of 1,050 m and to a
vertical depth of 1,000 m. Note that Figure 1 presented here only
covers the upper portion of the Deposit (see the longitudinal section
accompanying the news release dated July 29, 2010 for a view of the
complete Deposit). Details on the Deposit can be found in numerous
Cornerstone and Thundermin news releases dated between May 1, 2007 and
November 30, 2010 which are on each company's website and on SEDAR.

A compilation of historical surface and underground diamond drilling
information obtained from the archives of the Newfoundland and Labrador
Department of Natural Resources, dating from the 1960's to the early
1970's and, some of which was not previously available, has recently
been completed. Drill logs and assay information for a total of 47
surface and 86 underground holes were recovered as shown on Figure 1
and listed in Table 2 at the end of this release. Six surface and 28
underground holes lie outside of the area of drill indicated
mineralization shown on Figure 1. The assay results for seven of the
underground holes were included in a news release dated February 25,
2009 but this data was not incorporated in any resource estimates as
the drill logs for these holes were not previously available.

Figure 1 shows the areas in the upper portion of the Deposit that were
mined out, as well as the areas that were developed but not mined out,
by British Newfoundland Exploration Company from 1966 to 1972 and Green
Bay Mining Company from 1972 to 1974. All known mine workings and the
upper limit of the current NI 43-101 mineral resource estimate are also
shown on Figure 1.

Three holes of the current drill program totaling 966 m were completed
in December prior to the seasonal shutdown (see Figure 1). These three
holes were drilled to confirm the presence of high grade copper
mineralization known to exist in the upper portion of the Deposit (see
Figure 1 and Table 2:
http://www.cornerstoneresources.com/i/pdf/properties_LD_11-03Table2.pdf). Hole LD-10-39, which intersected high grade massive, semi-massive
and stringer chalcopyrite-pyrite-pyrrhotite  mineralization over
significant widths (see Table 1), was drilled to confirm the copper
mineralization in historical surface hole LD-62-78 which intersected
2.9% Cu over 60.1 m, including intervals of 5.9% Cu over 7.9 m, 5.3% Cu
over 15.5 m and 3.1% Cu over 11.6 m (see Table 2). Hole LD-10-40, which
was drilled approximately 35 m west of LD-10-39, intersected minor
copper mineralization comprising 2.4% Cu over 0.7 m. Hole LD-10-41
(assays pending) was drilled approximately 50 m east of hole LD-10-39.
The current drill program will recommence shortly with two drills and
will be completed by June 30, 2011.

A preliminary interpretation of the recovered drill log and assay data
suggests that there is potential to add from 500,000 to 650,000 t of
copper mineralization, excluding the areas that were mined on two
occasions from 1966 to 1974, with grades similar to that already
estimated for the Little Deer Zone above the area of the mineral
resources outlined to date (see Figure 1 and Table 2). The potential
addition of these mineral resources to the total mineral resource
estimate for the Deposit is conceptual in nature and will need to be
confirmed by an independent Qualified Person ("Q.P").

Glen McKay, Cornerstone's President and CEO commented "The recently
compiled historical diamond drill information has provided us with a
better understanding of the potential in the shallower eastern portion
of the Deposit, as well as an improved understanding of the historical
underground infrastructure. We continue to be pleased with drilling
results and will be busy with two drill rigs operating in the first
half of the year, following our continued goal of increasing the
mineral resources".

Mineral Resource Estimate

On October 13, 2010, Cornerstone and Thundermin announced that an
updated NI 43-101 compliant mineral resource estimate had been
completed by Scott Wilson RPA under the supervision of Mr. Reno
Pressacco, M.Sc. (A), P.Geo., Senior Geologist for Scott Wilson RPA and
an independent Q.P. in accordance with NI 43-101. Scott Wilson RPA
estimated that the Deposit contains Indicated Resources of 1,150,500 t
at an average grade of 2.8% Cu within the Little Deer Zone and
additional Inferred Resources of 1,227,300 t at an average grade of
2.2% Cu within the Little Deer Zone and 1,108,200 t at an average grade
of 1.9% Cu within the Footwall Zone. A NI 43-101 compliant Letter
Report entitled "Mineral Resource Update for the Little Deer Project"
dated September 30, 2010, to support the updated mineral resource
estimate, is available on Cornerstone's and Thundermin's websites.

Metallurgy

On October 19, 2010, excellent metallurgical results from scoping level
test work on core samples from the Deposit were announced. This work,
which was undertaken at SGS Lakefield Research Limited ("Lakefield") of
Lakefield, Ontario, indicates that a saleable, high grade copper
concentrate grading over 28% copper with over 97% recovery and free of
any deleterious elements can be produced from the Deposit. The use of a
simple rougher-cleaner flowsheet, a common xanthate collector, pH
control with lime and a relatively course primary grind for copper
liberation from mineralization of medium hardness suggest that the
operating costs should fall into the low range for any metallurgical
plant constructed to treat the Little Deer copper mineralization.

Qualified Person

Mr. Andrew Hussey, P.Geo., Project Geologist and Lands Manager,
Cornerstone Resources Inc., is the Q.P. responsible for supervising the
drilling program and the compilation of all of the historical data on
the Deposit for the purposes of NI 43-101. Mr. Hussey has also reviewed
the contents of this news release for accuracy. All holes drilled by
Cornerstone and Thundermin are NQ in size. Specific gravity
measurements, rock quality designations and photographic logging of
significant mineralized intersections are performed systematically
prior to assaying. The core is logged and the mineralized sections,
where appropriate, are sawn in half at a core logging facility in
Springdale. Half of the core is submitted for analyses to Eastern
Analytical Limited, an independent and qualified assayer located in
Springdale, and the remaining half of the core is kept for future
reference. Blanks, duplicates and standards are routinely used as part
of the assay procedures.
