CODELCO NORTE Challenges and Opportunities • Continue to mitigate geotechnical risk by monitoring and unloading. • Improve “control” of ongoing operations – benchmarking and operational excellence integration. • Investigate pre-stripping of RT and acceleration of MMH open pit as opportunities to mitigate risk. • Revisit high arsenic issue - a long term strategic perspective considering market- values of concentrates and environmental restrictions. • Reassess the mill expansion strategy - requires a rigorous quantitative approach that fully considers associated risks but also the opportunities to expand production capacity based on our significant mineral resources potential. • Reevaluate Toki and bioleaching of low grade sulphide resources to mitigate exhaustion of MS an RT leacheable ore.
