Abstract

The uranium deposit at Kvanefjeld is situated in the alkaline complex of Ilímaussaq 
in South Greenland. The deposit belongs to the category of disseminated magma tic 
low grade uranium resources; the presently known resources are 27,000 tons U in 
the class of reasonably assured resources and 16,000 tons U in the class of estimated 
additional resources. The ore body is still open in two directions and the possibility 
of increasing the resource figures considerably is high. The average grade of the ore 
is 340 ppm U. The exploration work has reached a detailed development stage and 
material is being mined at present for extraction tests on the refractory ore.
The exploration history dates back to the middle fifties and during the subsequent 
25 years the deposit has been investigated with varying intensity. Yet its economic 
feasibility has not been proven and the decision on development or not awaits the 
results of the metallurgical pilot plant tests and the solution of a number of 
environmental and legal questions. A period of three to five years is expected before 
a final decision can be made.
The character of the exploration in the area is determined by the fact that exploration 
licences for radioactive materials are traditionally not given to private mining 
companies in Greenland. The Kvanefjeld deposit has accordingly been explored by 
Danish state institutions without direct commercial interest in the development and 
no centrally coordinated exploration, metallurgical and environmental study has been 
carried out. The progress in the exploration has therefore been largely governed by 
the initiatives of single institutions.
