  • Mesquite Mine is a rare permitted multi-million ounce U.S. gold reserve, one of only a handful of such opportunities in the United States
  • Proven and Probable reserves of 2.36 million ounces of gold and Measured and Indicated resources of 1.25 million ounces1
  • Average annual production of 165,000 ounces of gold planned commencing April 2008
  • Company recently listed on the Toronto Stock Exchange
Toronto, Canada, September 22, 2006 -- Western Goldfields, Inc. (TSX:WGI, OTC BB:WGDF.OB) today announced the commencement of a major 70,000-foot reverse circulation drilling program, designed to expand the non-oxide mineral resource base at its Mesquite Mine in Imperial County, California. The drilling program is consistent with Western Goldfields' decision to proceed quickly with bringing this exceptional gold mining opportunity into production by April 2008. The Company is estimating average annual production of 165,000 ounces of gold from the mine, with an initial project life of 9-1/2 years.

Initial test work from the Mesquite Vista pit non-oxides conducted by Newmont Metallurgical Services indicated a recovery of gold in concentrate of more than 80 percent, suggesting excellent potential for enhanced gold recovery from a gravity and flotation circuit program. Samples from the drilling program also will be used for further metallurgical test work to optimize gold recovery going forward. The Layne Christensen Company of Chandler, Arizona, is conducting the reverse circulation drilling program.

"After reviewing the geologic database supporting the reserve estimate described in the recent Feasibility Study, it is apparent that many of the drill holes in the mine area stopped in mineralized non-oxide material," said Mr. Raymond W. Threlkeld, President and Chief Executive Officer. "The Feasibility Study indicated proven and probable reserves of 2.36 million ounces of gold and measured and indicated resources of 1.25 million ounces (1). The potential to increase resources appears excellent. Mesquite is already permitted for development which will make it possible to expand our production in a remarkably short time."

Western Goldfields announced the findings of the Feasibility Study in a news release on August 9, 2006, and the results can be found on Western Goldfields' website. The resource and reserve estimates are summarized in the Appendix to this news release.

"The Mesquite Mine is a unique gold mining opportunity, in that it is a fully permitted, multi-million ounce reserve in a politically safe location -- one of only a handful of major deposits owned by an independent company in the United States," said Mr. Randall Oliphant, Chairman, Western Goldfields. "The Mesquite Mine should form a very solid and profitable foundation on which we can create increasing value for the shareholders of Western Goldfields. We also intend to pursue additional precious metals opportunities that are emerging in our industry, particularly in North America," added Mr. Oliphant.

Western Goldfields, Inc.

Under a new, highly experienced, and dynamic management team, Western Goldfields is a gold producer focused on completing the expansion of its Mesquite Mine, located in Imperial County, California, and returning the mine to full production. Western Goldfields acquired the Mesquite property in 2003 from Newmont Mining Corporation. Newmont originally operated the mine until 2001 when it ceased production, as the low gold prices at that time did not support expansion plans. However, Newmont continued the permitting process for expansion, and the permits were approved in 2002. Western Goldfields has continued producing gold from ore placed on heaps by the previous owners, and expects gold production in 2006 to be about 14,000 ounces.

Western Goldfields, Inc. recently began trading on the Toronto Stock Exchange under the symbol WGI. The Company currently has 69,187,051 common shares issued and outstanding and 111,369,230 shares of common stock on a fully diluted basis.
