Economic mineral resources: activities in 1990

Abstract

The most exciting discovery in mineral exploration in Greenland in 1990 was announced by Platinova Resources Ltd. and Corona Corporation. A single packsack drill hole intersected a gold-platinum rich zone in the layered mafic Kap Edvard Holm complex of East Greenland (Fig. 1). The mineralised zone consists of an upper gold-rich section overlying a platinum-rich section. Gold values averaged 2.6 ppm over 1.5 m while the bottom section of the hole yielded 3.4 ppm platinum. Surface sampling indicates that the platinum mineralisation extends 1.5 to 2 m below the bottom of the drill hole. The mineralised zone occurs in a well-defined layered sequence which can be followed for more than 10 km.
