"This agreement also removes the financial burden of the underlying property payments and advances our business model by having other companies finance exploration on our properties.""We are excited to work with Southern Copper, a major producer who brings development and production experience to Cerro Samenta. Argentina has received some bad press suggesting that it is a poor place to invest. We disagree with this assessment and point out that not only is SC planning to explore and develop projects in Argentina but other major companies such as Chevron, Agrium, Barrick, and Xstrata are also spending billions of dollars on new projects."
