Ann: Mineral Resource Upgrade, page-304

question. i am interested in your perspective but i don't really understand how adding more capacity is necessarily more difficult or complicated.

like hypothetically if they could design and build a production line that can process a modest 5mtpa, would it necessarily be any more complicated to just build four of the exact same for a 20mtpa output?

just want to understand why you are saying that scale adds complexity. what would you say is the practical limitation that makes it difficult

There is plenty of power, water and space available
