Book Description
This report summarizes the results of the 1998 National Mineral Resource Assessment that estimated the gold, silver, copper, lead, and zinc in undiscovered deposits in the United States. This project also estimated the identified resources and past production of these five metals. Assessment results include the following:• It is estimated that 18,000 metric tons (t) of gold, 460,000 t of silver, 290,000 kilotons (kt) of copper, 85,000 kt of lead, and 210,000 kt of zinc are in undiscovered deposits minable with existing technology.• In addition, it is estimated that 15,000 t of gold, 160,000 t of silver, 260,000 kt of copper, 51,000 kt of lead, and 55,000 kt of zinc remain in identified resources.• Past production from the largest identified resources of gold, silver, copper, lead, and zinc is estimated to be 12,000 t of gold, 170,000 t of silver, 91,000 kt of copper, 41,000 kt of lead, and 44,000 kt of zinc. These deposits account for about 99 percent of cumulative domestic production in the United States.

Book Description
Governance of the World’s Mineral Resources: Beyond the Foreseeable Future provides in-depth information on the geological scarcity of mineral resources. The book demonstrates the urgent need to implement sustainable utilization of mineral resources, in order to ensure that these resources will be sufficiently available for future generations too. The availability of resources, especially for modern technologies, is an increasingly important issue. Some key mineral resources are so geologically scarce that their availability for future generations may not only become substantially less, but also much less affordable than for the current generation unless timely measures are taken. This book provides detailed data and calculations of the availability of mineral resources. The book elaborates on whether and how it is possible to keep providing sufficient mineral resources to a growing world population, and for how long. The book details also how and for how much time it will be possible for all countries, worldwide, to achieve and maintain service delivery of raw materials to their population at levels equivalent to those in developed countries in 2020. Governance of the World’s Mineral Resources: Beyond the Foreseeable Future is therefore an important source of knowledge for postgraduates, academics and researchers in the fields of environmental science, sustainability, and geology, as well as anyone in the field of mining and economics who need to account for sustainable provision of mineral resources. Provides a thorough overview of all considerations related to a sustainable production rate of mineral resources Comprehensively details scarce mineral resources and describes their applications, worldwide in-use stock increases, and sustainable production rates Covers all aspects of a sustainable production rate of mineral resources, detailing the current challenges and possible global solutions, both technically and from a policy point of view Includes detailed studies of thirteen different scarce mineral resources and extensive quantitative data from recent studies and in-depth research

Book Description
In this volume, a group of distinguished international scholars provides a fresh investigation of the most fundamental issues involved in our dependence on natural resources. In Scarcity and Growth (RFF, 1963) and Scarcity and Growth Reconsidered (RFF, 1979), researchers considered the long-term implications of resource scarcity for economic growth and human well-being. Scarcity and Growth Revisited examines these implications with 25 years of new learning and experience. It finds that concerns about resource scarcity have changed in essential ways. In contrast with the earlier preoccupation with the adequacy of fuel, mineral, and agricultural resources and the efficiency by which they are allocated, the greatest concern today is about the Earth‘s limited capacity to handle the environmental consequences of resource extraction and use. Opinion among scholars is divided on the ability of technological innovation to ameliorate this 'new scarcity.' However, even the book‘s more optimistic authors agree that the problems will not be successfully overcome without significant advances in the legal, financial, and other social institutions that protect the environment and support technical innovation. Scarcity and Growth Revisited incorporates expert perspectives from the physical and life sciences, as well as economics. It includes issues confronting the developing world as well as industrialized societies. The book begins with a review of the debate about scarcity and economic growth and a review of current assessments of natural resource availability and consumption. The twelve chapters that follow provide an accessible, lively, and authoritative update to an enduring-but changing-debate.
