In a potential tenement expansion in Greenland, Ironbark Zinc (ASX: IBG) has lodged a tenement application adjacent to the wholly owned Mestersvig Licence, which contains high grade zinc-lead mineralisation.
The potential new tenement covers 461 square kilometres which includes the Sortebjerg 'Black Mountain' base metals prospect.
Ironbark recently received data from 16 diamond drill holes drilled under the outcropping mineralisation at Black Mountain in 1952, which the company said confirms the continuation of mineralisation at depth.
The major benefit for Ironbark if the new tenement is granted by the Greenland Bureau of Minerals and Petroleum, is that the adjacent Mestersvig Licence containing the Blyklippen lead zinc mine proving mineralisation in the area.
The Blyklippen mine was operated from 1956 to 1962 and yielded production of 544,600 tonnes for a recovered grade of 9.9% zinc and 9.3% lead.
Ironbark currently considers the Blyklippen life of mine at 6 years at above 12% lead.
Importantly, the mining town and wharf are still located at Nyhavn, just 8 kilometres north east of Blyklippen.
