Grønnstein
A Norwegian mineral exploration company. Mainly targeting Ni-Cu-PGE deposits hosted in Palaeoproterozoic greenstone belts.
Grønnstein AS
Grønnstein AS was founded in 2021 by four geologists who graduated from UiT - The Arctic University of Norway. Whilst Grønnstein AS is for recreational purposes, the focus is to identify new Ni-Cu-PGE deposits as these elements will be in high demand during the green transition. Reconnaissance field work has been undertaken at a number of high-potential areas (2021-2023); the Karasjok, Kautokeino and Ringvassøy greenstone belts as well as the Alta-Kvænangen and Mauken tectonic windows.
What is a grønnstein?
"Grønnstein" is the Norwegian word for greenstone. It is a metamorphic rock characterized by its green color from minerals such as chlorite, epidote, and actinolite. Greenstones are formed by low-grade metamorphism, usually from mafic volcanic rocks such as basalt, and are known to host major ore deposits in large-scale greenstone belts.
