What are the key commercial terms outlined in 5E Advanced Materials' second non-binding indication of interest for boric acid and calcium sulphate?

The second non-binding indication of interest (IOI) contemplates an annual offtake of 3,750–4,500 short tons of boric acid and calcium sulphate over five years at a fixed price with annual escalation, contingent upon successful product qualification and consistent production.

How does this second IOI relate to 5E Advanced Materials' broader project development goals?

This milestone follows a prior 10-year offtake agreement and reinforces the commercial viability of the Fort Cady project, directly supporting its path toward a Final Investment Decision.
