Tyler Reports Further Mineralized Intercepts at North Skarn Target

CALGARY, ALBERTA--(CCNMatthews - Aug. 1, 2006) - Tyler Resources Inc. (TSX VENTURE:TYS) is pleased to announce further mineralized intervals for its North Skarn target, including 5 meters at 1.81% copper and 4.2 g/t silver.

Analytical data for 4 core holes and 4 reverse circulation holes have been received from the initial drill testing of the North Skarn Zone, located approximately 3 kilometers north west of the Bahuerachi Main Zone porphyry system where an initial independent resource calculation is underway.

Assay results to date from drilling in the North Skarn shows the presence of wide spread but discontinuous anomalous to locally high grade copper mineralization with locally elevated zinc, silver, and gold values. The results confirm the discovery of an extensive new mineralized area at the Bahuerachi project, and the presence of mineralized skarn highlights the possibility that a mineralized intrusive center may be discovered in this area with further work.

Results are presented in the following table and discussed below. Updated geological sections for the drill holes as reported is posted with the news release on our website at www.tylerresources.com. Drill hole collar locations are shown on the attached drill plan map:

All holes are interpreted to be testing true widths of mineralization.

Reverse circulation drill holes RC-37 and 38 as well as core holes BAH-87 and 89 locally encountered elevated metal values, however, these elevated values did not result in significant composite intervals. One drill hole (Bah-92) remains outstanding for the North Skarn target at this time. Follow-up work on the North Skarn area going forward will focus on regional surface and alteration mapping in order to vector towards a possible intrusive source for the skarn alteration and mineralization identified to date.

Field Update

Work is ongoing in the Main Zone at a reduced rate during the ongoing rainy season in Mexico, which is expected to last until Mid-September. 4 drill rigs are currently drilling in both the Main Zone porphyry and North Lobe porphyry systems.

About Tyler

Tyler Resources is a junior exploration company focused on base and precious metals exploration in Mexico. Tyler's primary project is the Bahuerachi property, which hosts a large mineralized porphyry-skarn copper (Au, Ag, Mo, Zn) complex. The Company is now in the advanced stage of a 35,000 meter combined diamond and reverse circulation drilling program scheduled to be completed during 2006, making it one of the most active Canadian junior exploration companies operating in Mexico.

All assay work was performed by ICP at ALS-Chemex labs of Vancouver, with gold done using standard fire assay methods. All samples sent to the lab are sealed with security tags for delivery to ALS-Chemex. Duplicate samples as well as standards and blanks are inserted in each batch of samples delivered to the laboratory and then checked to ensure proper quality assurance and quality control (QA/QC).

The Qualified Person responsible for the design and implementation of the Field Program as well as the preparation of this news release was J. P. Jutras, P.Geol., and President of the Company. The work program is being carried out with the participation of Dr. Shane William Ebert, Ph.D, P.Geo, Vice President and Director, Dustin Rainey, B.Sc Geology, Grant Couture, B.Sc., M.Sc Geology, Paul Turnbull, B.Sc, P.Geol and Cornell McDowell, B.Sc Geology, consultants to the Company.
