Regulators and investors now expect tailings studies to read like risk registers, not static stability memos. Numerical models support that shift when mechanisms and uncertainties are named upfront.
Framework elements we document on every study:
• Governing mechanisms — static, rapid drawdown, liquefaction, piping
• Material models justified against lab and in-situ test ranges
• Consequence mapping tied to inundation scenarios, not abstract FoS
• Monitoring hooks for pore pressure and deformation at critical sections
Re-run models when material placement changes — tailings beaches evolve faster than many annual review cycles assume.
