Edit: I meant to leave this empty to start, but to clarify now that there’s other discussion:

“Access to minerals” doesn’t necessarily mean “discounted” or “mineral rights”. It could be a deal consisting of:

1. Military aid goes to EU defence industry supplies
2. In exchange, EU gets first dibs at market rate contracts (with some tax-exempt on on the EU side for imports to make it more appealing to take advantage of on both sides) for metals/mineral extraction.

This could help spur Ukraine’s post-war economy, integration with EU markets, and benefit the EU defence industry. It would also demonstrate what a real and fair deal looks like.
