Zinc deposit consisting of 5 major mounds of sedimentary-exhalative type.

It the most northerly base metal mineralization presently known in the world. The mineral deposit was discovered in May 1993 by Platinova A/S during a reconnaissance exploration programme and it has been investigated by mapping, drilling and geophysical surveys during the period 1993–1997. A preliminary estimate of the total tonnage of sulphides encompassed by the two ore-bearing argillaceous units – the Footwall shale(Unit 8) and the Middle mudstone units (Unit 6) – exceeds 350 million tons. In the Discovery, Beach and Esrum areas, three main sulphide levels occur within a 200 m thick stratigraphic interval. In the fourth mineralized area – the West gossan area – one level of mineralization is delimited although disseminated suphides with slightly enhanced Zn values occur at various overlying stratigraphic levels. The Citronen Fjord massive sulphides form a stratiform deposit displaying clear evidence of deposition on the sea floor contemporaneously with the enclosing sediments. It is interpreted to have formed at relatively low temperatures by the precipitation of sulphides from metal-bearing fluids introduced onto the sea floor from underlying fractures. It is thus placed in the sedimentary-exhalative class or SEDEX class of sulphide deposits.
