Tyler Resources Announces Widest Mineralized Drill
Intersection to Date at Bahuerachi

CALGARY, ALBERTA--(CCNMatthews - Jan. 10, 2005) - Tyler Resources Inc.
(TSX VENTURE:TYS) is very pleased to announce assay results for its
drill hole 04-BAH-15 which returned an intersection of 143 meters with
an average grade of 0.71% copper from 16 to 159 meters. This was
followed by 5.6 meters grading 2.15% copper, 0.24 g/t gold, 31 g/t
silver and 0.62% zinc from 160.7 meters to 166.3 meters where the hole
ended in mineralization. Interval details are tabulated below.

Including(b) 160.7 166.3 5.6 2.15 0.62 31 0.24 Breccia/skarn

(a)From 159 to 160.7 meters, all core was lost during the drilling
process and no sample was recovered.

(b)The drill hole ended in mineralization before reaching its total
planned target depth. In previous status updates, drill hole #15 was
described as ending at 176.6 meters. The correct final depth is
166.3 meters.

Diamond drill hole #15 was drilled to the east (090 degrees) with a dip
of -70 degrees. It is located approximately 100 meters north of diamond
drill hole 04-BAH-05 for which results were previously reported. Please
refer to the drill hole location plan map provided with the December 14,
2004 news release for the general location of drill hole #15. A section
reporting grades and geology will be prepared once all drilling planned
on this section has been completed.

Tyler personnel and field crews have now returned to camp and diamond
drilling is expected to resume this week. Tyler and its drilling
contractor have now made arrangements to bring to site PQ and NQ
diameter drill rods in addition to the HQ size rods previously used.
This will allow the Company greater operational flexibility where
difficult ground conditions are encountered and should facilitate
drilling all further holes to planned target depths.

Further changes to the Reverse Circulation drilling program are also
being implemented. Reverse Circulation drilling remains a widely used
technique in this type of environment and is used to cost effectively
determine the extent of large relatively homogeneous bulk mining
targets. At Bahuerachi, the Company's objective is to bring the accuracy
of reverse circulation drilling to within 10 to 20% of core drilling and
establish a good control over geostatistical assay result variability
with further twinning of core holes. Accordingly, the reverse
circulation rig will first twin diamond drill hole #15 as a second
variability test. After doing so and while assay results for the second
twinned hole are pending, the RC rig will be used to do first pass
prospecting drilling on targets outside of the Main Zone porphyry such
as the Los Alisos gold-silver epithermal system and a number of
geophysical targets on the property which require further investigation.
Core drilling will continue as planned on the Main Zone target.

Tyler is also pleased to announce that as a result of the exercise of
warrants arising from its 2004 financing, an additional $1 million in
funds will be assigned to the Bahuerachi 2005 field program, allowing
the company to expand its Phase 2 program and provide increased
flexibility to test additional targets.

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.
