World Copper Ltd is a copper-focused company with established oxide copper resources in Arizona, US, and Chile. Because the impact on the environment of oxide copper projects is substantially less than that of traditional sulphide flotation mining, World Copper believes its two oxide copper resources will have a friendly path to production. Zonia, in Arizona, has a Net Present Value of $447 million using $4 copper. Escalones is Chile's largest oxide copper project, in development. A Preliminary Economic Assessment will be available by early February.
