Ironbark Zinc exploration at the wholly owned Mestersvig project in Greenland is returning some very promising results including visible base metal mineralization over multiple meter true widths.

Highlighting the prospectivity at Mestersvig is historical mining and production which included 544,600 tonnes at 9.9% zinc and 9.3% lead in the 6 years to 1962. New drill samples from Mestersvig are being air freighted from Greenland this week and will be shipped for assay by ALS Chemex in Europe.

Ironbark said that drilling activity for 2011 has now mobilized from the Mestersvig site to the Citronen base metal project. Exploration at Citronen is ongoing and primarily aimed at resource definition and infill drilling at the Esrum zone in conjunction with extensional drilling around areas of higher grade mineralization at the Beach zone.

Citronen currently has a Inferred JORC Resource of 59.9 million tonnes at 5.9% zinc plus lead with the latest exploration targeting the conversion to the higher confidence categories of Measured and Indicated.

At the Washington Land project, Ironbark will target follow up exploration at the Cass prospect from work conducted by Rio Tinto in the late 1990's with the big miner withdrawing due to the low zinc and lead prices.

Mineralization at Cass occurs over 4 kilometer strike where continuous rock chip composite samples returned; 25 meters at 8.9% zinc, 11.1% lead and 95 gram per tonne silver.

A second continuous rock chip composite sample taken 550 meters along strike to the east returned; 25 meters at 3.7% zinc, 7% lead and 40 gram per tonne silver. A single diamond drill hole yielded 1.2 meters at 8.4% zinc 0.04% lead and 94 gram per tonne silver.
