The Zeehan smelter operated intermittently from 1898 and 1948 recovering lead, silver and copper from the processing of locally mined ores and ore concentrates. However, the technology at that time did not allow for the recovery of zinc and hence the zinc from the processed material ended up in relatively inert zinc slag heaps or dumps on site.
After completing a 7-hole air core drilling programme to assist in verifying historical drilling data and to enable an upgrading of the mineralisation to a JORC 2012 Indicated Resource status, Tartana Minerals Limited then signed an agreement with MCC Non-ferrous Trading LLC to sell shipments of low-grade furnace slag/matte to South Korea.
Tartana Minerals Limited has now completed 16 shipments using local contractors and exported over 300,000 tonnes through the Burnie Port.
At the completion of the shipments Tartana Minerals Limited in conjunction with neighbouring lease holders plans to rehabilitate the site. This will be a significant achievement given the site has remained in its current state for more than 70 years but has interesting historical features.
