Marigold Mine is a run of mine heap leach operation that commenced production in 1988. The mine was transformed from a modest, conventional milling operation into a large and extremely efficient heap leach mine. Exploration led to the discovery of the Millennium ore body in the southern reaches of the property which then led to the Millennium Expansion project.
Goldcorp has a 66 2/3% interest in the Marigold mine and Barrick holds the remaining 33 1/3% interest. In 2007, the Company’s share of gold production from the Marigold mine amounted to 93,900 ounces of gold. Marigold is expected to produce gold through to 2017.
