@Solvetheriddle you beat me to it - I was just about to link the podcast, too!

Matt: [00:22:55] And is the competitive landscape today with BHP and Rio that they're currently doing their own version of InfraCo internally, and it's just not having the same success that MinRes is having with regards to that specific division and the capabilities?
Fraser: [00:23:11] I think that's probably a fair way of phrasing it. So if you take a BHP or a Rio, they will have some sites where a lot of crushing and processing is done by Mineral Resources already. But you can imagine for these types of businesses, they still feel it's important to have internal capability, and they've obviously invested tens of billions of dollars in their own infrastructure in rail, ports, processing and handling.
So they're kind of a hybrid model of using someone like Min's and their own internal capability. But as I mentioned, no one is debating any longer who was the more efficient operator. The BHPs and Rios would readily recognize and admit that MinRes is far more efficient, not only on the capital and construction side, but also on the operating side.
I think Chris recently mentioned that MinRes is kind of in the order of 30% more efficient on a 12-hour shift than their peers. So there's a steady march if you want to lower your costs and drive more profitability to potentially use a partner such as MinRes. And MinRes doesn't really have any competition, particularly in the crushing side of their infrastructure, which is the key service they offer to third parties.
