Stage 2
In addition to the strong performance of the Stage 1 operation during the year, Crosslands remains focused on progressing the Stage 2 expansion project.
Crosslands’ progressive upgrade of resources at
In June 2008, Crosslands reported a significant increase to its JORC compliant mineral resources at
The DSO mineral resource of 96.6 million tonnes is made up of 77.1 million tonnes of Indicated and 19.5 million tonnes of Inferred Resource at 59.1% Fe
The BFO mineral resource is made up of 80.2 million tonnes of Indicated at 36.5% Fe and 354.6 million tonnes of Inferred Resource at 34.7% Fe.1
Preliminary metallurgical test work including approximately 350 Davis Tube Recovery tests indicates that the likely weight recovery for the BFO Mineral Resource is in the order of 30 to 35%.
Using this assumption, the current BFO Mineral Resource equates to 130 to 152 Mt of potential concentrate at a grade in excess of 66% Fe giving a total of 227 to 249 Mt when added to the DSO Mineral Resource.2
Importantly, this increased mineral resource represents only 40% of the total strike length to be tested under the resource expansion program underway at Jack Hills. Resources are consequently expected to continue to grow as this program continues with further announcements to be made through the 2009 financial year.
As a result of this major resource upgrade, the Stage 2 Mine Feasibility Study was expanded to allow metallurgical testwork and resource definition work to incorporate the BFO materials.
The BFO mineral resource, reported to JORC standards, is supported by the preliminary metallurgical test work, referred to above, which indicated that a range of high grade, high quality concentrate products could be economically produced from BFO using conventional crushing and grinding followed by low intensity magnetic separation.
