Mineral-Project Closure Provision: Cash-Flow, Accounting and Security-Deposit Reconciliation

By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026

2-minute summary

A bank guarantee or other financial assurance is security for regulatory performance; it is not automatically equal to the accounting provision.
The physical plan should map reclamation, rehabilitation, fencing, water/environmental measures, dismantling and monitoring to quantities, timing and responsible owners.
Cost estimates should distinguish current-price engineering estimates from discounted accounting measurement and from cash collateral/security requirements.
Release of financial assurance depends on satisfactory compliance/certification under the rules, so forecast cash should not assume release on the nominal mine-closure date without evidence.

Current position

Mine closure requires three reconciliations that should not be collapsed: physical closure obligations, statutory financial assurance/security and the accounting provision/cash forecast. MCDR 2017 contains progressive/final mine-closure and financial-assurance mechanisms, but an accounting liability must be measured under the applicable reporting framework and facts.

Control and evidence map

#	Control	What the file should show
1	Closure-scope register	Approved progressive/final closure commitments and physical quantities.
2	Cost estimate	Vendor/engineering basis, inflation/escalation assumptions and timing.
3	Accounting bridge	Opening provision, unwinding/accretion, additions, utilisation and reassessment.
4	Security bridge	Financial assurance amount/form, expiry/renewal and release conditions.
5	Cash plan	Closure capex/opex by year, security movements and post-closure monitoring.

Worked example

A mine carries a Rs 40 crore closure provision and a Rs 18 crore bank guarantee. Those figures are not inconsistent merely because they differ. Finance should reconcile what the provision covers, what the guarantee secures, expected closure timing, costs already incurred through progressive rehabilitation and the evidence needed before security can be released.

Common mistakes

Forcing the accounting provision to equal the bank guarantee.
Ignoring progressive rehabilitation already completed.
Forecasting immediate security release without certification.
Using an old closure plan after mine design or disturbed area changes.

Frequently asked questions

Is financial assurance the same as a mine-closure provision?

No. One is a regulatory security mechanism; the other is an accounting measurement under the applicable reporting framework.

Can progressive rehabilitation reduce future exposure?

It can affect physical obligations and, under MCDR mechanisms, relevant assurance calculations; retain certified evidence of work done.

What should be refreshed annually?

Closure scope, timing, unit costs, disturbed area, security, discount/inflation assumptions and regulatory status.

What source controls the statutory closure obligations?

The current MCDR/mining plan/approved closure documents and applicable amendments, not a generic accounting model.
