Tyler's Requested Voluntary Termination of US Registration Under the Securities Act of 1934 is Now Effective

CALGARY, ALBERTA--(Marketwire - Sept. 13, 2007) - Tyler Resources Inc.'s (TSX VENTURE:TYS) ("Tyler") application to voluntarily terminate its US Registration under the Securities Exchange Act of 1934, as amended, became effective on September 13, 2007.

The preparation time and costs associated with preparing US filings and meeting SEC regulatory requirements were substantial. By deregistering, the Company believes that it can realize significant ongoing general, administrative and legal costs savings, as well as have more time to focus on its core business activities. Tyler will publish the information required under Rule 12g3-2(b)(1)(iii) on its website at www.tylerresources.com. Tyler continues to trade on the TSX Venture Exchange under the symbol TYS.

Scoping Study Update

Tyler has been advised that work on the previously announced scoping study is progressing well, is in its final stages, and that results are expected shortly. Once received, the Company intends to release the scoping study results as soon as practicable thereafter.
