EY critical minerals report: project resilience and midstream risks for miners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
EY’s Net Zero Centre report “Risk and resilience: Rethinking Australia’s critical materials advantage in a disorderly world” urges Australia to move beyond being a raw ore exporter and secure a larger share of midstream processing for lithium, rare earths and other critical materials. The report flags geopolitical tensions and highly concentrated processing capacity – particularly in China – as key supply risks, and calls for targeted policy, finance and permitting reforms. For miners and processors, it signals stronger scrutiny of offtake security, downstream integration and project resilience in investment decisions.
Technical Brief
- Geopolitical tension is treated as a design parameter for offtake, not just a background uncertainty.
- EY links midstream investment decisions to resilience metrics such as diversification of processing jurisdictions.
- Financing structures are urged to reward projects with integrated mine‑to‑midstream flowsheets rather than standalone extraction.
- Permitting reform is framed around compressing approval timelines without diluting ESG and community safeguards.
- For similar projects, bankability assessments are expected to weigh supply‑chain concentration as heavily as orebody quality.
Our Take
‘Critical materials’ appears in only a handful of keyword-matched pieces in our database, so EY’s Australia-focused work sits in a relatively small but fast-growing cluster of policy analysis on supply security rather than on individual mine projects.
The Kazakhstan piece in our coverage (linking uranium and other critical minerals to a deliberate geopolitical brokerage role) suggests that if Australia follows EY’s recommendations, it will be competing not just on geology and ESG but on its ability to play a similar strategic intermediary role between major economies.
