Ironbark Zinc: drilling results show continuation of mineralisation at Mestersvig in Greenland

Ironbark Zinc (ASX: IBG) has received high grade base metal drilling results from the historic Blyklippen lead-zinc mine of 1.1 metres at 12.2% zinc and lead, and 8.2 grams per tonne (g/t) silver from 263 metres.

This is significant because it proves a down dip extension of over 200 metres for mineralisation below the historical workings.

The Blyklippen base metal mine was operated between 1956 and 1962 and produced 544,600 tonnes of high grade ore in excess of 20% zinc and lead for a recovered grade of 9.9% zinc and 9.3% lead.

Unmined drill zones at the mine returned up to 5.2 metres at 18.5% zinc and lead from 40 metres. Blyklippen has been estimated to have a six year mine life at plus 12% lead. 

Ironbark has targeted deeper extensions and along strike to the south approximately 350 metres below surface (130-150 level) and has intercepted a blind continuation of the north-trending mineralised structure as exploited in the Blyklippen mine.

The company drilled three diamond holes and all intersected the mineralised structure. Further drilling is warranted at Blyklippen to define the extent of the high grade.

Ironbark also conducted a three hole diamond drilling program at the Sortebjerg prospect. The drilling targeted extensions of observed base metal mineralisation hosted in steeply dipping, north-trending fault zones.

Drilling was successful and all three drill holes intersected zinc, lead and silver mineralisation

The Blyklippen mine is part of the Mestersvig Project in Greenland where Ironbark is also conducting regional exploration, which has delivered highlight intersections of 2.5 metres at 8.9% zinc and lead, and 2g/t silver, as well as 1 metre at 17.3% zinc and lead, and 4g/t silver.

Ironbark is encouraged by the results and is planning further exploration work for 2012.
