Tyler Resources New Corporate Presentation and Field Update

CALGARY, ALBERTA--(Marketwire - Oct. 26, 2007) - Tyler Resources Inc. (TSX VENTURE:TYS) ("Tyler") is pleased to report the publication of a new corporate presentation on its website which provides further information on its recently announced Scoping Study, or Preliminary Economic Assessment, including views of the currently defined PEA open pit shells.

Furthermore, Tyler would like to provide a field update, and provide guidance on the anticipated flow of news over the coming weeks.

Drilling is ongoing with 2 core rigs (diamond drilling) and 1 reverse circulation rig. Over the last week, the Company has increased its diamond drilling capacity from 2 shifts to 4 shifts to accelerate testing of critical areas in the Main Deposit between now and December. This will ensure the maximum amount of data possible for the next Resource Estimate Recalculation, is scheduled to start on or about December 15th with Associated Geosciences Limited.

Tyler has also requested acceleration of all analytical work at the lab for ongoing assay work on completed drill holes. As has been its procedure over the year, the Company will be releasing drill results in batches that allow for a proper interpretation of the results on an ongoing basis.

Drill holes for which assay results are currently outstanding include:

Main Bahuerachi Deposit expansion to the West.

Diamond Drill holes # 124 (bottom) section 6NE, DDH-125 (Western Edge of PEA pit), DDH-126 (section 2 NE), DDH-127 (section 7 NE). Drill holes DDH-128 (section 8 NE) and DDH-129 (section 7NE). Drill hole #125 intersected target units at depth, but had to be stopped short of the mineralization due to technical difficulties in drilling. Drill Holes # 124, 126, 127, 128 and 129 have all intersected the main target mineralized units outlined in previous resource estimate work and the PEA report, and significantly extended the mineralization to the west of the previously defined deposit limits.

Reverse circulation drill holes outstanding include RC 89, 97, 98 and 99, 100 and 101 between sections 66N and 4 NE. RC holes 97 to 101 are all meant to be re-entered with the diamond drill rig, and were done to accelerate testing of the deposit's west side by using the faster RC drilling technique in the top portions of these holes.

Cerro Prieto Area

7 reverse Circulation drill holes were completed at the Cerro Prieto area. Cerro Prieto is an area of new high-grade surface skarn targets associated to large intrusive bodies. Recently released surface trenching results included : 55 meters grading 8.8% Zinc, 0.25% Copper and 8.7 g/t Silver as well as 7 meters grading 14.75% Zinc and 7.6 g/t Silver.

This area represents a new grassroots target with clear high grade potential which had never previously been drilled. It is anticipated that full results for drill holes RC-90, 91, 92, 94, 95 and 96 will be received and released within the next two weeks, concurrently with diamond drilling assays.

Other - The Company currently has 113,278,378 common shares, 12,066,827 warrants and 5,330,000 stock options outstanding. In the past few days, approximately $450,000 has been received from warrant exercises and with the outstanding warrants significantly "in the money", a further $8.4 m could be injected into the Company. Tyler has $7.5 m cash in hand and is fully funded to complete pre-feasibility and feasibility studies in 2008.
