Tyler Resources Announces Increased Drilling Capacity and 1,938 Hectares Increase in Land Position at Bahuerachi

CALGARY, ALBERTA--(CCNMatthews - Oct. 27, 2005) -

Contracted an additional 20,000 meters of drilling with three rigs

Tyler Resources (TSX VENTURE:TYS) is pleased to announce a further expansion of its drill program for the Bahuerachi project, Mexico. A third diamond drill rig is currently being mobilized to site.

The company has now finalized drilling contracts to undertake a minimum additional 20,000 metres of exploration drilling on the Main Zone and other drill targets at Bahuerachi. The next 12,200 meters are planned to complete a wide spaced first pass drill testing of the entire 4 kilometer mineralized porphyry complex, while maintaining flexibility to tighten drill spacing in areas with positive drilling results (see attached general drill plan). The third diamond drilling rig for the project is currently being mobilized from Canada and is expected to be on site by mid-November.

Using current drilling production rates, the Company expects to have completed its first pass drill testing of the main Bahuerachi porphyry and related high grade skarn system by May 2005. The Company will continue releasing drill results form the ongoing program on a regular basis.

The Company is also continuing its efforts to source a reverse circulation drill rig, which would be used for both infill drilling as well as reconnaissance drilling of lower priority targets.

NEW LAND TITLE

In other developments, the Company has now received title to the Bahuerachi 5 concession, adding 1,938 hectares to its current property position to the west and north (see map). The new title covers land with known showing of both base and precious metals, including high grade shear/vein hosted gold (0.8 to 18.5 g/t Au) as well as base metal bearing skarns and related porphyry to the north. Ongoing field work will now focus on better defining new grassroots targets in order to upgrade them to the drill stage as drilling continues on advanced targets in the Main Zone.

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 was carried out with the participation of Dr. Shane William Ebert, Ph.D, P.Geo and Director, Mr. Brent Gonek, B.Sc, Geology, G.I.T., Mr. Dustin Rainey, B.Sc. G.I.T, consultants to the Company.
