PGEs are indispensable many industrial applications but mined only a few places....
This study estimates the location, quality, and quantity of undiscovered copper in stratabound deposits within Neoproterozoic Roan Group Katanga Basin Democratic Republic Congo Zambia. The area encompasses Central African Copperbelt, greatest sediment-hosted copper-cobalt province world, containing 152 million metric tons greater than 80 deposits. (1) delineates permissive areas (tracts) where may occur 2 kilometers surface, (2) provides a database known prospects, (3) numbers these tracts...
The platinum-group elements, platinum, palladium, rhodium, ruthenium, iridium, and osmium, possess unique physical chemical characteristics that make them indispensable to modern technology industry. However, mineral deposits are the main sources of these elements occur only in three countries world, raising concerns about potential disruption supply. Using information public domain, resource reserve has been compiled for mafic ultramafic rocks South Africa Zimbabwe host most world's element...

This study synthesizes available information and estimates the location quantity of undiscovered copper associated with a late Permian bituminous shale, Kupferschiefer, Southern Basin in Europe. The purpose this is to (1) delineate permissive areas (tracts) where reduced-facies sediment-hosted stratabound deposits could occur within 2.5 kilometers surface, (2) provide database known reduced-facies-type significant prospects, (3) probabilistic amounts that be present each tract. assessment...
Mineral resource assessments integrate and synthesize available information as a basis for estimating the location, quality, quantity of undiscovered mineral resources. This probabilistic assessment sandstone copper deposits within Paleoproterozoic metasedimentary rocks Kodar-Udokan area in Russia is contribution to global led by U.S. Geological Survey (USGS). The purposes this study are (1) delineate permissive areas (tracts) indicate where sandstone-hosted may occur 2 km surface, (2)...
The Central African Copperbelt (CACB) is one of the most important copper-producing regions world. majority copper produced in Africa comes from this region defined by Neoproterozoic Katanga sedimentary basin southern Democratic Republic Congo (DRC) and northern Zambia. Copper CACB mined sediment-hosted stratabound deposits associated with red beds includes giant Kolwezi Tenge-Fungurume districts DRC Konkola-Musoshi Nchanga-Chingola In recent years, structurally controlled replacement vein...

The Stillwater Complex in Montana hosts significant platinum-group element mineralization; one deposit, the J-M Reef has been mined since 1986. In 2000, a frequency-domain airborne electromagnetic (AEM) and magnetic survey was flown to aid exploring for new deposits. US Geological Survey (USGS) given access this dataset recently made data public (https://doi.org/10.5066/P9OLEU17). initial investigations into AEM utilized raw create apparent resistivity maps. addition, individual channels...
