GCC ACQUIRES READY-MIX ASSETS IN SOUTH DAKOTA AND MINNESOTA

Chihuahua, Chih., Mexico, January 5, 2006

The acquired companies, Consolidated Ready Mix, Inc., Henrich and Sons, Inc., Huron Steel Structures, Inc., and B&B Concrete, Inc., generate approximately US$ 30 million in revenues annually from 14 strategically located ready mix plants with a fleet of 100 ready-mix trucks.

This acquisition will enhance the GCC´s leadership position in the competitive cement markets of South Dakota and surrounding regions and position the Company to benefit from anticipated growth in demand for concrete, while immediately augmenting the GCC´s net sales and EBITDA.

The group of companies, which are the leaders in the markets where they compete, will be operated as Consolidated Ready Mix, Inc. by its current management as a wholly-owned subsidiary of GCC.

"This acquisition represents a unique opportunity for GCC to secure its long-term leadership position in a growing market. At the same time, our regional clients in the construction industry will benefit from the full-service cement and ready mix concrete offering we can now provide," said Manuel Milan, Chief Executive Officer of GCC.
