27-year mine plan includes four-phase pit design targeting
production of:
• 14.5 million tons of pozzolan at rates up to 500,000t
per year.
• 1.3 million tons perlite at rates up to 100,000 t per year
(for 15 years)
Low strip ratios: 0.25 tons waste per ton ore in Main Zone,
0.16 in Tuff Zone, most waste mined after Year 8.
