Ironbark Gold receives encouraging results from metallurgical testwork program in Greenland
Australian based resources company Ironbark Zinc (ASX: IBG) has further confirmed the metallurgical and technical merits of its wholly owned Citronen Zinc-Lead Project in Greenland, with excellent interim results from recent metallurgical testwork and geotechnical work.
Ironbark Managing Director Jonathan Downes said the company considered the results to be extremely encouraging, with all information be used as part of the ongoing Definitive Feasibility Study, expected to be complete by the end of 2010.
"Ironbark has received excellent initial results from the metallurgical testwork program currently ongoing at the AMMTEC Burnie Research Laboratory in Tasmania," Mr Downes said.
The testwork was based on samples from the Citronen Project.
During the afternoon trade, shares in Ironbark were up 2.4% to 21.5c.
A whole ore flotation on Beach Level 2 was conducted, from which a concentrate grade of 50% zinc with a recovery of 90% was achieved using an optimised reagent regime.
The result was achieved using conventional grinding and flotation circuits. Other ore zones will be tested later in the program and results announced as they become available, however the Beach Level 2 Zone will represent the bulk of the first eight years of planned ore feed.
The expected flowsheet for the plant will incorporate Dense Media Separation (DMS) to remove waste material at coarse sizes, followed by a traditional flotation plant.
Snowden was engaged to conduct geotechnical appraisal of the project, which utilised five geological drill holes completed during the 2009 field season and historical data.
This work determined that Citronen is amenable to both open pit and underground mining techniques. The results are very encouraging and remove a significant amount of project risk as well as offering potential benefits for reduced operating and capital costs.
Ironbark’s key focus is the wholly owned Citronen base metal deposit in Northern Greenland that currently hosts in excess of 10 billion pounds of zinc and lead. The current JORC compliant resource for Citronen (November 2008) is 55.8 million tonnes at 6.1% zinc (Zn) + lead (Pb); Indicated resource of 29.9Mt @ 5.8% Zn and 0.6% Pb and Inferred resource of 25.9Mt @ 5.0% Zn and 0.7% Pb.
