Tyler Resources Announces Continued Mineralization at
the Bahuerachi Main Zone, Including 16.9 Meters
Grading 0.80% Copper, 13.7 G/T Silver and 0.31% Zinc
in Diamond Drill Hole #17

CALGARY, ALBERTA--(CCNMatthews - Feb. 24, 2005) - Tyler Resources Inc.
(TSX VENTURE:TYS) (OTCBB:TYRRF) is pleased to announce assay results
recently received for drill hole #17 and the bottom portion of drill
hole #16 at the Main Zone of its Bahuerachi project.

The bottom portion of Drill Hole #16 was completed upon project start up
in mid January. The hole was completed from 152 meters to its target
depth of 217.2 meters. The extended portion of drill hole #16 revealed
fairly consistent mineralization with grades typical of those sought in
this type of geological environment. Significant intervals are quoted in
the table below. The hole ended in mineralization.

Drill hole #17 was drilled on a section trending 120 degrees located
roughly 100 meters north of drill hole #16. It also intersected the
target skarn breccia unit and mineralized intrusion at depth. The hole
ended in sheared QFP grading 0.28 % copper and 0.017% molybdenum at a
depth of 215.9 meters.

Significant Intervals drill holes #16 (bottom) and #17 are presented in
the table below.

(a) 32 to 148 meters results previously released on January 25th, 2005


Drill holes BAH-18 (located north of drill hole #17) and BAH-19 (located
south of previously released hole RC-2) have been completed and have
been sent to the laboratory for assay. Drill hole BAH-20 has also been
completed and is being logged and sampled in preparation for shipping to
ALS Chemex Labs. Core drilling at the Main Zone is currently continuing
according to schedule with Drill Hole BAH-21. A series of regional
exploration reverse circulation drill holes (#12 to 16), testing targets
in the NW part of the property, have also been shipped for assay.

Further adjustments have been made to the reverse circulation portion of
the drilling program and an additional twin test is underway. Once the
twin is completed under the revised methodology, the RC crew will take a
scheduled break of approximately 2 weeks. During this time the new
samples will be assayed for verification that sample recovery has
further improved and can be considered statistically reliable at
Bahuerachi's main zone.

Please refer to the drill hole location plan map attached for the
general location of drill hole. Sections are currently being prepared
incorporating the new drilling information with the previously released
results for BAH-16 (top), RC 4 and RC5 and will be published once final
interpretations are completed.

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, and Mr. Brent Gonek, B.Sc, Geology, G.I.T.,
consultants to the Company.
