Quantitative mineral resource assessment of copper, molybdenum, gold, and silver in undiscovered porphyry copper deposits in the Andes Mountains of South America
(U.S. Geological SurveyUS, 2008)
Quantitative information on the general locations and amounts of undiscovered porphyry copperresources of the world is important to exploration managers, land-use and environmental planners, economists, and policymakers. ...
Quantitative mineral resource assessment of undiscovered porphyry copper resources in South America
(Geological Society of AmericaUS, 2007)
A quantitative resource assessment to be published this fall identifies and evaluates 26 tracts in South America where the geology isconsidered permissive for the occurrence of porphyry copper deposits. For each tract, ...
