Ironbark is listed on the Australian Securities Exchange (ASX: IBG) and specialises in base metal exploration and development in Greenland and Australia.
Ironbark seeks to build shareholder value through exploration and development of its projects and also seeks to actively expand the project base controlled by Ironbark. The management and board of Ironbark have extensive technical and corporate experience in the minerals sector.
Ironbark’s key focus is the Citronen Zinc-Lead deposit in Northern Greenland.
Ironbark Zinc follows up high grade intercept with new 35m @ 9.6% Zinc assay
In addition to the stunning high grade intercept from Hole 249 reported previously, of 16 metres @ 20.8% zinc, Ironbark Zinc's (ASX:IBG) follow-up drilling has revealed a new high grade intersection from the XX Zone at Citronen Fjord in Greenland.
The potentially significant point from this, is that the majority of the flat-lying strata-bound mineralisation at XX Zone has not been effectively explored, representing another significant exploration opportunity and potential for a larger resource upgrade than expected.
Drill hole CF10_271A was drilled to test a structure and identified in CF10_249 (which returned 16 metres @ 20.8% zinc announced on 21 September 2010) and returned; 35m @ 9.6% Zn+Pb from 61m including 21m @ 14.4% Zn+Pb including 7m @ 22.3% Zn+Pb.
Clearly, the results are highly encouraging for Ironbark as the inclined “scissor” drill hole was orientated 180 degrees opposite from CF10_249 and 45m further along strike in order to provide information of potential true width of the mineralisation.
Based on the results, Ironbark said it is confident that the structurally controlled mineralisation in this part of the deposit is over 10m in true width and CF10_249 did not drill down dip into the structure.
The sub-vertical structurally controlled mineralisation at the XX Zone is more complex than the majority of the flat-lying strata-bound mineralisation at Citronen and due to the predominantly vertical drilling conducted to date, has not been effectively explored and represents an exciting exploration opportunity.
The intercept in CF10_249/271A contains both remobilised mineralisation and strata-bound mineralisation typical of the Citronen deposit.
Mineralisation in the XX Zone has not been included to date in any published resource estimates for Citronen Fjord with the most recent resource quoted in November 2008.
A revised resource for Citronen incorporating the +20,000m of diamond core drilling completed since November 2008 is expected in the December quarter of 2010.
Total drilling on site to date is now in excess of 62,000m of diamond core drilling.
Drilling has concluded for the 2010 field season on site and further releases will be made as all assays are compiled.
