Tyler discovers High-Grade Molybdenum Zone in Bahuerachi’s South Porphyry with 19.76 meters grading 0.35% Molybdenum, 0.31% Copper and 11.5 g/t Silver

Tyler Resources Inc. is pleased to announce further drill results from its ongoing drill program, including the discovery of a new high-grade molybdenum-copper-silver zone in the South Porphyry, roughly 0.8 kilometer south of its Main Zone Bahuerachi Deposit, Mexico.

Assay data from 10 widely spaced scout RC drill holes and 2 diamond drill holes in the South and North lobe porphyry targets have been received. New mineralization identified by this drilling includes near surface, low-grade gold and silver mineralization in the North Porphyry (RC-53 and 54), a new zone of mineralization in the South Porphyry including high molybdenum grades (RC-60), and the continuation northwards of the Main Zone mineralized porphyry-skarn system at depth (BAH-101).

Significant results for these drill holes are presented in the following table and discussed below.  A geological cross section for drill hole BAH-101 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.

Significant Intervals - North and South Porphyry

(1)

Excludes 32.5 meters of unmineralized dykes

(2)

Excludes 4.4 meters of unmineralized dykes

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

The Company is encouraged by these new mineralized intervals.  The discovery of high-grade molybdenum in the South Porphyry, which remains largely untested, adds to the Bahuerachi project areas with molybdenum grades comparable to those of stand-alone molybdenum mines and development projects in other parts of the world. The discovery of higher near-surface precious metals values in the North Porphyry than have typically been seen in the Main Zone also adds to the exploration potential of the project.

Results for several of the other RC drill holes during this period showed widespread but generally narrower mineralized intervals.  In the North Porphyry, RC- 56 intersected 0.33% copper over 1.52 meters (6.08-7.60 m) and 0.5% zinc over 1.52 meters (114-115.52 m). RC-57 intersected 0.3% zinc and 1.7 g/t silver over 9.12 meters (0-9.12 m) and 0.44% copper and 2.6 g/t silver over 1.52 meters (54.72-56.24 m).  Diamond drill hole BAH-104 was abandoned due to difficult ground conditions before reaching its target depth.

In the South Porphyry, RC-59 intersected 0.17% copper, 0.033% molybdenum and 2.6 g/t silver over 4.57 meters at the bottom of the hole (169.21 to 173.78 meters). RC-61 intersected 0.2% copper and 5 g/t silver over 4.58 meters (42.68-47.26m).

Field Update and Ongoing Development Program

Drilling is ongoing with 3 rigs operating in the Main Zone, targeting additional tonnage accretive to the initial resource estimate (RC-63 to 70) as well as aiming to upgrade certain areas in terms of resource classification from the inferred to indicated category (BAH-108).  

Based on an ongoing study of the 3D block model of the Main Zone Deposit, the Company will focus on three drilling objectives over the coming months.  The first objective is to obtain sufficient information through drilling to model well-mineralized sediments and calc silicate skarns.  This data will add tonnage to the current resource estimate and lower potential stripping ratios during the preliminary assessment of the Bahuerachi Deposit currently underway.  The second objective is to upgrade the classification of the high grade skarn resource from inferred to measured and indicated by increasing the density of drilling data. This will allow for a preliminary economic assessment study of a high-grade starter operation at Bahuerachi.  The third objective is to selectively infill drill holes in the higher grade and near surface portions of the porphyry resource to upgrade the resource classification of a significant amount of material from inferred to indicated or measured categories.

Results currently outstanding include drill holes RC-63, 64, 65, 66, 67, 68, 69, 70 and core holes BAH 103, 105 and 106 (see attached location map).

About Tyler

Tyler Resources is a 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 scheduled to be 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).

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, M.Sc Geology, Paul Turnbull, B.Sc, P.Geol and Cornell McDowell, B.Sc Geology, consultants to the Company.
