“…Due to the size and remoteness of Greenland, geological mapping and geological research were rather limited and sporadic before World War I, so was mineral exploration and mining apart from a few spots close to accessible coasts. The first modern reviews providing a general overview of Greenland's mineral occurrences were published by Nielsen (1973Nielsen ( , 1976, who together with more general geological overviews including comments on economic geology (Henriksen 2008(Henriksen , 2015Henriksen et al 2000) provide a good framework for understanding the exploration history and resource potential (Fig. 1).…”

Greenland has a long mining and mineral exploration history and offers interesting possibilities for investors. There is still optimism in the mineral business, but successful examples are surprisingly few in the new millennium. Based on numerous new tables compiling information on companies, periods, targets, licenses, and costs, this paper gives a description of the past and present activities, the exploration companies involved, their main targets, their limited financial power, and their continued need for and search of investors and large industrial partners. An analysis of the key drivers at different levels is presented: analogues with Canada and elsewhere, dedicated prospectors looking for profit, specific strategic projects, commodity prices, new research results, co-financing, strategies, and regulations by authorities in Greenland and Denmark. Changes in political agenda in Greenland, Denmark, and internationally have had a strong influence on exploration activities in Greenland compared to other countries with an exploration industry, in some cases creating good incentives for investors, in other cases being showstoppers for future exploration and mining. This paper provides, for the first time ever, a summary of the total costs for mineral exploration in Greenland and the total revenue for the governments, and compares these numbers with the public investments in research, data acquisition, and direct investments in national companies.

“…In both evaluations only the Tertiary intrusive complexes are attributed a good potential, mainly for molybdenum and base metals. Nielsen (1973), in his summary of mineral occurrences in Greenland, included selected examples from central East Greenland, and the same data are presented in the monographs "Geology of Greenland" (Nielsen 1976) and "Mineral Deposits of Europe" (S0rensen et al 1978). A more comprehensive review, which however only incorporates the mineralization hosted in parts of the pre-Caledonian sediments, has recently been published (Stendal & Ghisler 1984).…”

“…In continuation of an aeroradiometric survey carried out jointly by Nordmine and the research establishment RIS0 in 1970, GGU conducted an open-spaced aeroradiometric reconnaissance programme in central East Greenland in 1971 (Nielsen 1972 andNielsen 1973). A more comprehensive flight programme was carried out in 1973 (Nielsen & Larsen 1974), and the results from both years are summarized by Nielsen & L0vborg (1976) .…”

The present monograph on the mineral occurrences of central East Greenland is the result of an agreement between Nordisk Mineselskab A/S and the Mineral Resources Administration of Greenland (Råstofforvaltningen for Grønland) on compilation of the mineral-exploration activity carried out in central East Greenland by Nordisk Mineselskab A/S during the period 1952- 1984. The main aim is to present geological descriptions of all known mineral occurrences and to compile most of the existing geochemical data in a manner applicable to future exploration in the area. More than 200 individual mineral occurrences are described and many in great detail. Geochemical data are presented for scheelite and for 16 elements relevant to the evaluation of the mineral potential of the area. The data are presented as single-element anomaly maps for both rock samples and panned heavy-mineral concentrates and include data from a file consisting of more than 10 000 rock samples and close to 4000 panned heavy-mineral samples. Mineralization in central East Greenland occurs in rocks of Archaean to Oligocene age and has tentatively been grouped into several periods when mineralization took place. Mineralization hosted in Archaean-Lower Proterozoic rocks includes magnetite and chromite accumulations and iron-sulphide segregations associated with ultramafic and mafic igneous assemblages, volcanogenic massive-sulphide occurrences, titaniferous magnetite and ilmenite occurrences associated with original plutonic anorthositic massifs, banded iron-formations, gold-bearing quartz veins, a complex copper-skarn occurrence, and uranium and gold-uranium occurrences of unknown origin. Mineralization hosted in Middle and Upper Proterozoic rocks is restricted to lead-zinc and tungsten skarns and stratiform copper occurrences. Mineralization hosted in Lower Palaeozoic rocks is in general believed to be associated with Caledonian orogenic activity. It comprises tungsten skarn occurrences mainly associated with granodiorite intrusions, base-metal and tungsten mineralization associated with late-kinematic probably calc-alkaline granite, tin-tungsten-arsenic quartz veins associated with late-kinematic probably mildly alkaline granites, gold-bearing quartz veins associated with late-kinematic granite, uraniferous veins in probably Devonian alkaline granite, tungsten-antimony-gold and silver-bearing base-metal veins in low-grade metamorphic sediments, uranium-fluorite veins in Devonian felsic volcanic rocks and strata-bound uranium occurrences hosted in Devonian elastic rocks. Mineralization hosted in Upper Palaeozoic sediments (Carboniferous - Permian) includes base-metal quartz-baryte veins locally enriched in precious metals, goldbearing quartz veins. uraniferous veins, carbonate-hosted strata-bound baryte base-metal occurrences, carbonate-hosted strata-bound celestite occurrences, stratiform base-metal showings of Kupferschiefer type and strata-bound red-bed copper occurrences. Mineralization hosted in Mesozoic sediments is represented by Triassic stratiform and strata-bound base-metal occurrences of red-bed type and Jurassic placers rich in zirconium and rare-earth elements. Tertiary mineralization includes a major porphyry-molybdenum occurrence, granite roof-zone molybdenum mineralization, niobium mineralization associated with alkaline intrusive rocks, lead-zinc skarn occurrences, a minor magnetite-skarn showing, lead-zinc-bearing quartz veins and precious-metal, base-metal, molybdenum and fluorite mineralization associated with fumarolic volcanic activity. The location of all mineral occurrences is shown on a separate map: Mineral Occurrences in Central East Greenland.
