Tyler Applies to Terminate Its Registration in the United States

CALGARY, ALBERTA--(Marketwire - June 14, 2007) - Tyler Resources Inc. ("Tyler") announces that it has applied to voluntarily terminate its US Registration under the Securities Exchange Act of 1934, as amended, in order to realize substantial cost and time savings and better focus on its Canadian listing on the TSX Venture Exchange (TSX VENTURE:TYS).

Pursuant to recently adopted Rule 12h-6(h) of the Exchange Act, Tyler has given notice today that it intends to terminate the registration of its common shares under section 12(g) of the Exchange Act and to terminate any of its remaining reporting obligations under section 13(a) or section 15(d) of the Exchange Act. To this end, Tyler has filed today with the US Securities and Exchange Commission a certification on Form 15 in order to effect such termination. Tyler expects that this termination of registration will become effective 90 days after its filing with the SEC. As a result of this filing, Tyler's obligation to file certain reports with the SEC, including an annual report on Form 20-F and reports on Form 6-K, will immediately be suspended. Tyler will publish the information required under Rule 12g3-2(b)(1)(iii) on its website at www.tylerresources.com

The US average daily trading volume has been less than 5% of the average daily trading volume of Tyler's common shares on a worldwide basis over the previous 12 months. The preparation time and costs associated with preparing US filings and meeting SEC regulatory requirements are 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.
