Forecast Production Clause Samples

Forecast Production. Recoverable Resources for the Duddar Pb-Zn Underground Mine have been estimated at approximately 9.9Mt. The “2005 Basic Design Report” itemised ‘Mineable Quantities’ by 50m vertical increments in the underground mine. This allowed an accurate estimation of tonnes and grade. Each mining method had varying dilution rates and recovery rates, which were used along with the percentage of production for each mining method to estimate recoverable Pb and Zn metal quantities. The upper stopes would be put into production ahead of schedule when the second year of infrastructure is completed, while the whole mine would be put into full production when the third year of infrastructure is completed. Based on Mineable Quantities estimates of 9.13Mt, the Duddar Pb-Zn Mine has an approximate mine life of
