La Colorada Gold/Silver Mine
Project Location and Summary:
The past producing La Colorada gold-silver mine property is located approximately 40 km southeast of Hermosillo, Sonora State, Mexico. La Colorada originally operated as a high-grade underground mine, which closed at the start of the Mexican Revolution in 1914. During the main historic mining period from 1876-1914 the production of more than three million ounces of gold was recorded.
In I990, the Mexican Geological Service (SGM) measured 1.5 million tons of tailings that were utilized at the start of the open pit production by Eldorado Gold Corp in 1993. During the period 1993-2000 Eldorado Gold Corp developed a bulk tonnage heap leach operation from several open pits; although the operation was sold in late 2000, production continued by a private Mexican owner until April 2002, yet La Colorada was never shut down for the lack of gold.
