Permitting and environmental approvals

What has to be approved

The core approval is usually the environmental impact assessment (EIA, or ESIA when social impacts are included). Around it sit many narrower permits:

Large projects may need dozens of permits from several agencies and levels of government.

The usual sequence

1. Baseline studies: at least a year, often longer, of water, air, wildlife and social data, so seasons are captured. Starting late is a common cause of delay.
2. Scoping: agreeing with the regulator what the assessment must cover.
3. Assessment: the EIA document itself, built on the mine plan from the PFS or feasibility study.
4. Review and consultation: public comment, agency review, often hearings and consultation with Indigenous groups.
5. Decision: approval with conditions, or refusal.
6. Appeals: in many countries, the decision can be challenged in court.

Timelines vary from a year or two in some places to the better part of a decade in others.

Why delay costs so much

Delay costs money in two ways. Every cash flow moves later, so it is discounted more. And the company keeps paying its team, its consultants and its licence fees while it waits.

That is before holding costs, inflation in the build cost, or the risk that metal prices are lower when the mine is finally ready.

Approval is not the end

• Conditions attached to an approval can add cost: monitoring, offsets, design changes.
• Judicial review can overturn or suspend an approval after it is granted.
• Changes to the mine plan later, such as an expansion or a new pit, may need new approvals.

What to take away

Check when baseline studies started, what the regulator still has to decide, and how long similar projects have taken in the same place. A study schedule that assumes approvals faster than local precedent is a red flag.
