Progressive rehabilitation: integrating closure, water, and liabilities from project design

Closure is no longer a late-life issue. It has become a design variable that influences mine sequencing, waste placement, residue management strategy, and total project cost.

A rigorous approach starts with early identification of liabilities: acid mine drainage potential, geotechnical instability, water contamination pathways, erosion, abandoned-infrastructure safety, and future land-use constraints.

Progressive rehabilitation addresses these risks at the pace of mining instead of waiting until the end of the cycle, when costs rise and technical flexibility drops. It also improves the credibility of ESG commitments with communities, investors, and regulators.

Terra Pretiosa supports operators through risk diagnostics, phased rehabilitation plans, water balances, and environmental monitoring frameworks that align regulatory compliance, cost control, and operational credibility.
