As is standard in the industry, CODELCO divides its mineral holdings into two categories, reserves and resources. Resources are ore bodies of economic value that have been identified and evaluated through exploration, reconnaissance and sampling. Reserves are the portion of the resource that can be extracted based on an economic, environmental and technological analysis set forth in the mining plan. Reserves and resources are both subdivided further, based on the degree of knowledge that CODELCO has of their extent and composition. The system used by CODELCO for categorizing mineral ore is widely used within the mining industry (and codified in such international regulations as the Joint One Reserves Committee (JORC) code of Australia, the South African Mineral Resources Committee (SAMREC), and the Reporting Code of Great Britain). Other systems of categorization are also used; one such system is that used by the U.S. Geological Survey. This presentation may not be taken away with you.
