TYLER RESOURCES ANNOUNCES BROKERED FINANCING

Tyler Resources Inc. (“Tyler” or the “Company”) is pleased to announce that it has entered into an agreement with Jennings Capital Inc. (the “Agent”) to act as agent on a “best efforts” basis for the placement of up to 16,000,000 Units (“Units”) of Tyler at CAD $0.50 per Unit (the “Offering”) for aggregate gross proceeds of up to CAD$8,000,000.  Each Unit consists of one common share (a “Share”) and one-half of one purchase warrant (a “Warrant”) of Tyler.  Each whole Warrant will entitle the holder to purchase one Share at an exercise price of $0.75 per Share for a period of 24 months from the date of closing of the Offering.  The Company also shall have the right to sell up to a maximum 2,000,000 Units directly to purchasers of its own choosing (“President’s Units”).

The Agent will receive a cash commission equal to 6% of the aggregate gross proceeds of the Offering, exclusive of the gross proceeds realized from the sale of any President’s Units, in respect of which the Agent will be paid a cash commission equal to 3% of the gross proceeds.  The Agent will also receive an Agent’s Warrant exercisable to purchase that number of Shares that is equal to 6% of the aggregate number of Units sold (net of President’s Units) and 3% of the aggregate number of President’s Units sold.  Each Agent’s Warrant will entitle the holder to acquire one Share at a price of $0.50 per Share for a period of 24 months from the date of closing of the Offering. The Agent shall have the option, exercisable at any time up to 48 hours prior to the date of closing of the Offering, to increase the size of the Offering by additional Units for aggregate gross proceeds of up to C$2,000,000.  & nbsp;If the Agent’s over-allotment option is exercised in full, then the Company shall have the right to allocate an additional 1,000,000 President’s Units.

The securities issued in the Offering will be subject to a hold period of four months plus one day from closing.  

The Offering is scheduled to close on or about March 12, 2007 and is subject to applicable regulatory and TSX Venture Exchange approval and completion of definitive documentation.  Proceeds from the Offering will be used for exploration expenditures, preparation of a feasibility study on the Company’s Bahuerachi property in Mexico and for working capital purposes.  

The Units will be offered by way of private placement exemptions in the provinces of Ontario, British Columbia and Alberta and such other jurisdictions within and outside of Canada as may be agreed to between the Company and the Agent. The Offering will not be available in the United States except under applicable registration exemptions under the United States Securities Act of 1933.
