Most junior boards inherit their insurance stack from the previous policy year. Broker sends a renewal quote, CFO presses sign, premium gets paid, policy sits in a drawer. This is the point at which the board is most exposed: when the cover looks adequate but has not been audited against the actual risk surface. Six gap patterns repeat.
| Gap pattern | What it covers (or doesn't) | What goes wrong |
|---|---|---|
| Regulatory investigation sub-limited D&O sub-limit |
Sub-limit for investigations, interviews and regulator-initiated inquiries, often AUD 500k to AUD 1m against a AUD 10-20m D&O limit. | Real-world cost of a sustained ASIC or WHS investigation burns through the sub-limit in weeks. The headline limit looks adequate; the responding limit is not. |
| NED extension assumed Side A carve-out |
Side A cover for non-executive directors, often sitting behind a specific carve-out the CFO has never read. | When the company becomes insolvent and Side B is unavailable, the NEDs find out the carve-out was there. By then the cover is unbuyable. |
| PI excludes contractual work Assumed liabilities exclusion |
PI policies typically exclude assumed liabilities — contracts the company has signed taking on liability beyond common law. | Junior explorers sign offtake term sheets, earn-in agreements and JV documents that quietly expand contractual liability. The board did not know the exclusion bites those. |
| Pollution carve-out, no EIL D&O + PI environmental exclusion |
Most D&O and PI wordings carve out gradual pollution. EIL is the standalone line that fills the gap. | Juniors often do not buy an EIL because the risk seems low, then discover the exclusion when historic bore or drill pad contamination emerges, or when a rehabilitation bond shortfall surfaces at relinquishment. |
| Insured-vs-insured I-vs-I exclusion |
Standard exclusion that bites where a director or former director is a party to the dispute. | Shareholder derivative actions can fall away entirely under the I-vs-I exclusion. The cover the board assumed responded to derivative claims may not respond at all. |
| Retroactive date | The date back to which the current policy will respond to acts and omissions. | New policies re-set the retroactive date. A director who has been on the board for four years may discover that the current policy only covers claims arising from acts in the last two years. |
Three insurance lines protect mining directors: Directors & Officers liability (D&O), Professional Indemnity (PI) for the company's conduct, and Environmental Impairment Liability (EIL). Each has exclusions and sub-limits that junior-miner boards consistently misread.
D&O covers personal liability for directors and officers. Most policies blend three components: Side A (direct cover for directors, survives insolvency), Side B (reimburses the company for indemnifying directors, usually voids in insolvency), and Side C (entity-level securities claim cover). When a director faces regulatory action or a shareholder derivative claim, Side A is what responds. When the company is asked to indemnify that director, Side B is what funds it.
PI covers the company's conduct in delivering its services. For a junior miner, that includes project assessment, feasibility work, regulatory approvals advice and joint-venture management. The policy excludes most contractual liabilities the company has assumed beyond common law.
EIL covers pollution liability for gradual contamination, historic site impacts and rehabilitation bond shortfalls. It fills a gap most D&O and PI policies explicitly carve out.
The headline limit on a D&O schedule is the number that gets quoted in the board pack. It is also the number that boards check first and exclusions check last. In a renewal pack, the order is reversed at the board's expense: limits are visible, exclusions are buried, sub-limits sit in a schedule three pages back. The audit only works if the order is corrected.
The limits tell you how much the policy will pay. The exclusions tell you whether it will pay at all.
The audit rule
Send these questions to the broker at least eight weeks before renewal. Start a spreadsheet. The answers become the decision matrix for the renewal conversation.
What is the sub-limit for regulatory investigations, interviews and inquiries? Is there a separate limit for legal costs? Compare the sub-limit to the realistic burn rate of a sustained ASIC or WHS matter, not the headline D&O limit.
Is Side A Difference in Conditions (DIC) cover available? If not, why not? What is the cost delta? Side A DIC is the layer that responds when the primary policy has carve-outs the board did not see at renewal.
What contractual liabilities are carve-outs in the PI policy? Have you reviewed the company's recent offtakes, JVs and earn-ins against the carve-outs? The exposure sits in documents already signed.
Is there a standalone EIL policy? If not, is there environmental cover under the D&O or PI? Confirm the gradual-pollution exclusion in writing, and confirm whether rehabilitation bond shortfalls are within or outside the EIL trigger.
What is the retroactive date on the D&O? Does it extend back before the oldest director's appointment? Any director whose tenure pre-dates the retroactive date is uncovered for acts in the gap window.
What triggers the insured-versus-insured exclusion? Does the policy respond to derivative claims? Ask for the exact wording. The exclusion is where shareholder derivative actions fall away if the wording has not been negotiated.
Insurance does not stand alone. It responds to the evidence the board produces — or fails to produce — when the duty is tested. A board that has narrow D&O sub-limits and weak duty evidence is a board facing two weaknesses at once.
Insurance is the second line of defence. The first is evidence that the duty was discharged. If the director-duty matrix is thin, insurance may not respond either. The interaction runs in both directions, and the board should be reading both lines together at renewal.
The shape of the interaction is consistent across the cases that go wrong:
