The Kupferschiefer of Germany and Poland that extends over 600km and has been mined from at least 1199 AD. Today, four mines are in production in Poland by KGMH, operating at depths of 800m 1,200m. The Kupferschiefer has produced 130Blbs of copper and over one billion ounces of silver.

Nov 17, 2020 Max cautions investors that the presence of copper-silver mineralization at Kupferschiefer is not necessarily indicative of similar mineralization
Sep 20, 2021 This provides further evidence that the mineralization at San Martin and is of the reduced facies sediment hosted copper-silver Kupferschiefer style All mineralization described above is located at Tabalosos East where the company is currently preparing an Environmental Impact Statement Declaraci n de Impacto Ambiental, or DIA study.
Group 11 exploration is a junior explorer looking for Copper in Germany. We believe the Polish model for exploring and developing the Kupferschiefer can be applied across the border. Geology ignores international boundaries. We have collated a unique dataset of drilling, geochemical and geophysical data acquired over hundreds of years and ...

Jan 16, 2015 Permissive tracts are delineated by mapping the extent of the Kupferschiefer that overlies reservoir-facies red beds of the lower Permian Rotliegend Group. More than 78 million metric tons Mt of copper have been produced or delineated as resources in the assessed tracts, with more than 90 percent of the known mineral endowment located in Poland.
This study synthesizes available information and estimates the location and quantity of undiscovered copper associated with a late Permian bituminous shale, the Kupferschiefer, of the Southern Permian Basin in Europe. The purpose of this study is to 1 delineate permissive areas tracts where undiscovered reduced-facies sediment-hosted stratabound copper deposits could occur within 2.5 ...
Sep 28, 2019 The maximum copper contents were found in Kupferschiefer samples S-48217.65 and Grochowice 357.17 as well as in Weissliegend specimens Grochowice 352.84 and S-4831.80. The silver content is high especially in Kupferschiefer samples up to 600 ppm in S-482 and up to 564 ppm in Grochowice 35.

Copper already gained a central role in pre-antiquity as it is one of the main components of bronze.The development of copper mining and smelting, albeit on a small scale initially, marked the end of the Stone Age.Until the transition from the Bronze Age to the Iron Age with the technologically much more demanding iron smelting, copper mines were one of the central geopolitical resources.
The similarities between Kupferschiefer and CESAR presented were basin characteristics, lithology, mineralogy, deposit parameters, grades and, origin of sulfur. A notable difference is the Kupferschiefer orebody starting at 500-metres below surface, whereas Maxs CESAR copper-silver mineralization starts at surface refer to Figure 1.

Summary Ore forming processes in sediment-hosted sulfide deposits are widely regarded to involve organic matter OM. However, the precise nature of interactions between OM and hydrothermal fluids are still debated as well as how the interconnected reactions develop over geological timescales. Here, we present results from an advanced characterization of organic matter in the Kupferschiefer ...
Dec 20, 2017 The Kupferschiefer is a copper-, polymetallic-, hydrocarbon-bearing black shale of the lowermost Zechstein Group of Permo-Triassic age 252 Ma in Germany and Poland. It is usually 1 m thick and underlies 600,000 km2, extending from Great Britain to Belarus for a distance of over 1500 km. At a district scale, copper has been mined for over 800 years since its discovery circa 1200 A.D ...
Kupferschiefer is a calciferous, carbon rich marly clay with finely dispersed sulfidic copper minerals, mainly chalcocite, bornite, and chalcopyrite. The ores also contain up to 20 other metallic and metalloid elements. Further, Kupferschiefer shaly facies are known to contain significant amounts of kerogen up to 20, enriched in metals such as uranium and precious metals 3.
