Perpetual Management – Challenges
• Inappropriate/inadequate initial closure• Lack of mine records, drawings or plans• Absence of a corporate memory• Complicated pre-acquisition corporate history• Historical adjacent land development/management did
not consider mine site• Uncertain closure end points (initially) • Imprecise ultimate financial liability estimate (initially)
Uncertainty
