Notes:
• Year 1 disturbance ~ 186 ha. i.e initial mine excavation, ore stockpile, tailings dam, etc.
• Year 2 disturbance ~ 114 ha. i.e 166 ha + 10 ha (pre year 3 mine excavation) -72 ha (this land will reach its natural land use after flooding.
• Year 3 disturbance ~ 104 ha. i.e 114 ha + 20 ha (year 3 mine excavation) – 25 ha (rehabilitation of half ore stockpile)
