Introduction The multidisciplinary research project 'Resources of the sedimentary basins of North and East Greenland' was initiated in 1995 with financial support from the Danish Research Councils (Stemmerik et al., 1996). In the 1996 field season, ore geological studies continued on the shale-hosted Citronen Fjord zinc-lead prospect in North Greenland (Figs 1, 2). Platinova A/S discovered the deposit in 1993, and has subsequently explored the area by means of geological mapping, gravity surveys and diamond drilling. About 30 km of diamond drilling have been completed, and a resource of over 20 million tons of stratiform ore with 7 % zinc and 1 % lead has been estimated (Platinova A/S, 1996a, b). An additional fault-controlled, high-grade zinc-mineralised zone was encountered in the north-western part of the ?Discovery Zone- in 1996 (Platinova A/S, 1996b).
