Tyler Reports Further Infill and Resource Expansion Drill Results for Bahuerachi Including 19.76 Meters Grading 2.24% Copper, 20.8 G/T Silver and 0.85% Zinc

CALGARY, ALBERTA--(CCNMatthews - March 22, 2007) - Tyler Resources Inc. (TSX VENTURE:TYS) is very pleased to announce further drill results from its ongoing drill program at the Bahuerachi project, Mexico.

Assay data from 2 deepened and 5 new RC drill holes, and one deepened and 2 new diamond drill holes have been received. All drill holes intersected their targets in areas where mineralized material had not been previously modeled and will assist in expanding the Main Zone Deposit resource base during the next resource estimate. All drill holes or portions of drill holes that enter or are within the existing model space have largely confirmed the existing resource model, increasing the Company's confidence in the validity of its third party geological and grade model.

Significant results for these drill holes are presented in the following table and discussed below. Drill hole collar locations are shown on the attached drill plan map. Two new sections showing general geology and grade distribution have been prepared for new drilling (Sections 2.5 NE and 400N) and can be found on the website at tylerresources.com. Other sections will be updated as full datasets are received.

Field Update

The drilling program is ongoing with 3 rigs operating in the Main Zone, targeting additional tonnage accretive to the initial resource estimate (BAH-117) as well as aiming to upgrade certain areas within the porphyry in terms of resource classification from the inferred to indicated category (BAH-116, RC-81).

Results currently outstanding include core holes BAH-112, 114, 115 and RC 72, 73, 78.

About Tyler

Tyler Resources is a well-funded Canadian junior exploration company focused on base and precious metals exploration in Mexico. Tyler's primary project is the Bahuerachi property, which hosts Mexico's fourth largest mineralized porphyry system. The Company is now in the advanced stage of a 35,000 meter combined diamond and reverse circulation drilling program extended into 2007, 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).

A map of the Bahuerachi project is available at: http://www.ccnmatthews.com/docs/322tys.pdf
