NEWS RELEASE

SOUTHWESTERN TO VOLUNTARILY TERMINATE ITS U.S. REGISTRATION

AND SEC REPORTING OBLIGATIONS

September 19, 2008

Vancouver, BC – Southwestern Resources Corp. (SWG-TSX) (“Southwestern” or the “Company”) announces that it has filed today a Form 15F with the U.S. Securities and Exchange Commission (the "SEC") to voluntarily terminate the registration of its common shares under section 12(g) of the Securities Exchange Act of 1934 (the “Exchange Act”). Southwestern expects that this termination of registration will become effective 90 days after its filing with the SEC. As a result of this filing, Southwestern’s reporting obligations with the SEC, including an annual report on Form 20-F and reports on Form 6-K, will immediately be suspended.

Southwestern’s consolidated financial statements are prepared in accordance with Canadian generally accepted accounting principles and the Company will continue to meet its Canadian continuous disclosure obligations through filings with the applicable Canadian securities regulators. As a Toronto Stock Exchange-listed reporting issuer, all of the Company’s filings can be found on the System for Electronic Document Analysis and Retrieval (SEDAR) at www.sedar.com.

The Company is current with all requirements under U.S. securities laws. It is not listed on any U.S. exchange and administrative burdens and costs associated with being a U.S. reporting company have significantly increased in the past few years, particularly in light of SEC Sarbanes-Oxley requirements. The preparation time and costs associated with preparing U.S. filings and meeting SEC regulatory requirements are substantial, and overall the Company’s management believes that these administrative burdens and their associated costs far outweigh any benefits derived from the Company's foreign issuer status with the SEC.

The Company has a number of significant projects, including the Liam gold-silver project in Peru in joint venture with Hochschild Mining plc.

Forward-looking Statements

Statements in this news release that are forward-looking statements are based on the current expectations, beliefs, assumptions, estimates and forecasts about the Company's business and the industry and markets in which it operates. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or implied by these forward-looking statements due to a number of factors, including but not limited to, the Company's access to additional capital to fund future activities, the loss of mineral properties or the inability to obtain mining licenses, the inherently risky nature of the Company's activities and its lack of experience in bringing an exploration property into production, its ability to repatriate any earnings, foreign exchange fluctuations, the political stability and economic uncertainty of those areas in which the Company carries on operations and the lack of infrastructure in those areas, title risks, the risks and uncertainties associated with joint ventures and the Company's reliance on third parties, statutory and regulatory compliance, the adequacy and availability of insurance coverage, the Company's dependence upon employees and consultants and fluctuations in mineral prices and other risks detailed in the Company's filings with the Canadian Securities Authorities.

These risks, as well as others, could cause actual results and events to vary significantly. The Company expressly disclaims any intent or obligation to update these forward-looking statements, unless the Company specifically states otherwise.

PART I

Item 1.

Exchange Act Reporting History

Southwestern Resources Corp. (the “Company”) first incurred the duty to file reports under Section 13(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) on or about November 10, 1999.

The Company has filed or submitted all reports required under Ssection 13(a) of the Exchange Act and corresponding Securities and Exchange Commission rules for the 12 months preceding the filing of this Form 15, and during that period has filed at least one annual report under Section 13(a).

Item 2.

Recent United States Market Activity

The Company has never sold securities in the United States in a registered offering under the Securities Act of 1933.

Item 3.

Foreign Listing and Primary Trading Market

The Company has maintained a listing of its common shares, without par value (the “Common Shares”) on the Toronto Stock Exchange (the “TSX”), the primary trading market (as defined in Rule 12h-6(f)) for the Common Shares, in Ontario, Canada (the “Primary Jurisdiction”).

The date of the initial listing of the Common Shares on the TSX was May 31, 1994. The Common Shares have been listed on the TSX since such date. Thus, the Company has maintained a listing of the Common Shares for a period that is longer than the 12 months preceding the date of the filing of this Form 15F.

To the best knowledge of the Company, for the period commencing on August 1, 2007 and ended on and including July 31, 2008 (the “Recent Trading Period”), the percentage of worldwide trading in the Common Shares that occurred in the Primary Jurisdiction was 95.1%, and as such the primary trading market is larger than the trading market for the Common Shares in the United States during the same period.

Item 4.

Comparative Trading Volume Data

The first day of the Recent Trading Period used to meet the requirements of Rule 12h-6(a)(4)(i) is August 1, 2007 and the last day of such period is July 31, 2008.

During the Recent Trading Period, the average daily trading volume of the Common Shares: (a) in the United States was 7,495 Common Shares, and (b) on a worldwide basis was 150,888 Common Shares.

During the Recent Trading Period, the average daily trading volume of the Common Shares in the United States as a percentage of the average daily trading volume of the Common Shares worldwide was approximately 4.9%.

The Company has not delisted the Common Shares from a national securities exchange or inter-dealer quotation system in the United States.

The Company has not terminated a sponsored American depository receipt (ADR) facility regarding the Common Shares.

The sources of trading volume information used for determining whether the Company meets the requirements of Rule 12h-6 are (a) with respect to the Common Shares traded on the TSX, the historical

trading information relating to the Common Shares as posted on the TSX website, and (b) with respect to the Common Shares traded in the United States, the historical trading information provided to the Company by Pink OTC Markets Inc. (formerly known as Pink Sheets LLC).

The average daily trading volume of its subject class of securities in the United States exceeded 5 percent of the average daily trading volume of that class of securities on a worldwide basis for the same recent 12-month period that the issuer used for purposes of Rule 12h-6(a)(4)(i);

(2)

Its subject class of securities was held of record by 300 or more United States residents or 300 or more persons worldwide, if proceeding under Rule 12(h)-6(a)(4)(ii) or Rule 12h-6(c); or

(3)

It otherwise did not qualify for termination of its Exchange Act reporting obligations under Rule 12h-6.

SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934, Southwestern Resources Corp. has duly authorized the undersigned person to sign on its behalf this certification on Form 15F. In so doing, Southwestern Resources Corp. certifies that, as represented on this Form, it has complied with all of the conditions set forth in Rule 12h-6 for terminating its registration under section 12(g) of the Exchange Act, or its duty to file reports under section 13(a) or section 15(d) of the Exchange Act, or both.
