mine ran profitably for +20yrs at much lower prices 5000.00 4500.00 4000.00 • Ceased production in late 1990s due to prevailing metal prices • Zinc price is 2x higher since mine shut down in 1997 (US$1.3k/t vs. US$2.6k/t) • Modernisation expected to boost economics further • Historical processing did not utilise preconcentration → potential increase feed grade and reduce capex • Greater
