Woodlawn Retreatment Project
TriAusMin has evaluated the potential to retreat in excess of 10 million tonnes of tailings that were deposited in three dams at Woodlawn, with the aim of demonstrating the feasibility of the tailings retreatment operation, the stand alone Woodlawn Retreatment Project feasibility study was completed in early July 2008.
Before taking a final development decision, the Company will incorporate into the study:
- An incremental Resource of 3.1 Mt of tailings (i.e. an increase of 36%) planned for recovery from the North, South and West Tailings Dams. Metallurgical test work is in process to confirm the expectation that the metallurgy of the material contained in the North Tailings Dam is consistent with tailings from the South and West Tailings Dams.
- Results from a technical peer review process that will be undertaken to ensure optimum outcomes in terms of engineering, procurement and contracting strategy.
- Results of discussions with potential off-takers of zinc, copper, and lead concentrates to firm up the potential marketing arrangements.
- Results of review of alternative funding strategies and the selection of a preferred funding strategy.
Upgraded WRP Mineral Resources
Following receipt of assays from drilling completed in December 2007, Mineral Resource estimates have now been finalised and or revised for the three Tailings Dams from which tailings will be recovered and processed as part of the Woodlawn Retreatment Project.
Based on an independent assessment performed by GeoRes the combined tonnage of Measured, Indicated and Inferred Resource contained in the North, South and West Tailings Dams has been increased by 36%, and is made up as follows:
|TAILINGS DAM SOUTH||Grade||Metal Content|
|TAILINGS DAM WEST||Grade||Metal Content|
|TAILINGS DAM NORTH||Grade||Metal Content|
