Wheaton River Minerals Ltd. (“Wheaton River”) is pleased to announce it has agreed to the sale of its La Guitarra silver/gold mine in Mexico to Genco Resources Ltd. (“Genco”) for US$5 million, subject to regulatory approval on behalf of Genco.  The US$5 million purchase price consists of US$100,000 cash and US$900,000 of Genco shares to be delivered on closing and US$4 million to be paid in cash or Genco shares, at Genco’s option, over eight years.

La Guitarra is located 100 kilometres southwest of Mexico City, and is the smallest and highest cost of the mining operations acquired in connection with the Luismin acquisition, completed in June 2002.  La Guitarra produced 13,400 gold equivalent ounces in 2002. 

 “This transaction will allow Luismin technical staff to focus on the continued growth and expansion of our other operations, and with Genco, La Guitarra will receive the attention required for a continued healthy operation,” commented Chairman and CEO Ian Telfer.

Wheaton River is also pleased to announce a joint venture agreement with Capstone Gold Corp. (“Capstone”) of Vancouver on the Ventanas Project, 120 kilometres west of Durango City, Durango, Mexico.  Ventanas is considered a geological twin to the prolific San Dimas epithermal gold/silver district (30 kilometres north), where Wheaton subsidiary Luismin operates the Tayoltita, Santa Rita, and San Antonio mines.  To date, over a dozen different epithermal systems have been identified at Ventanas.  Under the terms of the agreement, Capstone will spend US$5 million over four years to earn a 70% interest in Ventanas, at which point Wheaton River has the option to buy back to a controlling interest.
