11-37 - Cornerstone and Thundermin Commence 3,800 Metre Diamond Drilling Program on the 100% Owned, Past-Producing, Whalesback Copper Mine

--------------------------------------------------------------------------------

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. ("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) and 50% joint venture partner Thundermin Resources Inc. ("Thundermin") (TSX-THR) announce that they have commenced a diamond drilling program comprising approximately 3,800 metres in 13-15 holes at their 100% owned, past-producing, Whalesback Copper Mine ("Mine"). The Mine, which was in production from 1965-1972, is located approximately 10 km north of Springdale in north-central Newfoundland.
There is potential to outline significant copper resources at shallow depths adjacent to the Mine below and to the west of the old mine workings. The current drill program is designed to outline new copper resources which could, because of their proximity to the Little Deer Copper Deposit ("Deposit"), expand the total mineral resources available for mining and enhance the overall economics of establishing a new mining operation at Little Deer. At this time, the potential discovery of additional mineral resources at the Mine is conceptual in nature and it is uncertain whether further diamond drilling will result in the discovery of additional mineral resources.

Cornerstone and Thundermin own a 100% interest in the Deposit located approximately 800 m south of the Mine. Cornerstone and Thundermin have outlined significant copper resources at the Deposit since 2007 and the results of a Preliminary Economic Assessment ("PEA") for the Deposit, which was completed in October 2011, indicated that there is potential to develop the Deposit on an attractive economic basis at current metal prices. Information on the Deposit and the PEA is available in news releases issued between May 1, 2007 and November 1, 2011 and on Cornerstone's and Thundermin's respective websites and on SEDAR.

Whalesback Copper Mine
A digital compilation of 107 historical holes drilled in the mineralized zone below and to the west of the old mine workings suggests that there is excellent potential for establishing additional copper resources below and to the west of the areas previously mined. Significant results from the historical drill holes include 4.5% Cu over 6.1 m, 4.0% Cu over 3.4 m, 3.2% Cu over 5.5 m, 3.0% Cu over 4.3 m, 2.9% Cu over 8.4 m, 2.9% Cu over 6.1 m, 2.6% Cu over 4.6 m, 2.5% Cu over 5.3 m, 2.4% Cu over 9.1 m, 2.2% Cu over 5.8 m, 2.3% Cu over 3.1 m, 2.3% Cu over 3.4 m, 2.2% Cu over 8.5 m, 2.1% Cu over 13.1 m and 2.0% Cu over 8.5 m. These assay intervals all approach true widths as many of the holes were drilled from underground and others are of relatively shallow depth (see news release dated October 20, 2011 for additional information on the historical data recovered for the Mine).

Mineral Resource Estimate - Little Deer Copper Deposit
On June 22, 2011, Cornerstone and Thundermin reported an updated National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate for the Deposit comprising Indicated Resources of 1,911,000 tonnes at an average grade of 2.37% Cu (99.8 million pounds of copper) and Inferred Resources of 3,748,000 tonnes at an average grade of 2.13% Cu (175.9 million pounds of copper) (see Cornerstone and Thundermin news releases dated June 22, 2011).

Qualified Persons
Mr. Andrew Hussey, P.Geo., Project Geologist and Lands Manager, Cornerstone Resources Inc., is the qualified person ("Q.P.") responsible for the compilation of all of the historical data on the Mine for the purposes of NI 43-101. Mr. Hussey is also the Q.P. that is responsible for supervising the drilling program on the property. Mr. Hussey has reviewed the contents of this news release for accuracy and approved its release.

The positive PEA and the updated NI 43-101 compliant mineral resource estimate for the Deposit were prepared under the supervision of Mr. Eugene J. Puritch, P. Eng., President of P&E. Mr. Puritch is an independent Q.P. in accordance with NI 43-101.

Little Deer Joint Venture
Under the terms of its joint venture agreement with Cornerstone, Thundermin has the right to increase its interest in the Little Deer property to 75% by completing a feasibility study and by arranging 100% of the necessary bank financing required to place the property into commercial production.
