======================================================================= Re: News Release - 2009 - Monday, December 21, 2009 Canterra Minerals and Shore Gold Approve 2010 Buffalo Hills Exploration Program ======================================================================= Vancouver, B.C.

-- Canterra Minerals Corporation (CTM-TSX.V) ("Canterra") is pleased to announce that the Buffalo Hills Joint Venture Management Committee has adopted a $1.1 million Exploration Program for the Buffalo Hills Project located in Northern Alberta.

(See www.diamondex.net for project location and description.) The field portion of the 2010 program is focused on completing the delineation drill program that, to date, has resulted in the completion of 41 drill holes totaling 6,818 metres over three kimberlite pipes. Evaluation of the drill cores has advanced the development of three-dimensional geological models for the K6, K14, and K252 kimberlites.

Starting in February 2010, approximately 11 drill holes totaling approximately 1,980 metres will be completed on the K5 and K91 kimberlites and 4 additional drill holes will target priority grid locations on the K6 and K14 pipes.

Upon completion of the 2010 field work, it is expected that preliminary three-dimensional geological models will be completed for the K5, K6, K14, K91 and K252 pipes.

These models will guide the identification of "high interest" bodies for mini-bulk sampling in subsequent field programs. The Buffalo Hills project is a joint venture with Canterra (28.5%), Shore Gold Inc.

(28.5%), and EnCana Corporation (43%).

Canterra is the Operator of the Buffalo Hills Joint Venture with Canterra and Shore each contributing 50% of the exploration expenditures. David Clarke, P.Geol., MSc., Senior Vice President of Exploration for Canterra is a Qualified Person as defined by National Instrument 43-101 and is responsible for program design and quality control of exploration undertaken by Canterra.

In addition, forward-looking information is based on various assumptions including, without limitation, assumptions associated with exploration results and costs and the availability of materials and skilled labour.
