Yes I can see that POV.
However, what is the reality of using the third machine as a spare? These are pretty large pieces of kit.. The 2 HWMs are working in different areas. What's the logistic of getting the "spare" to cover if one break down? Can you even get it to the working face in one piece or does it need to be broken down and reassembled? If so, surely it's quicker to repair the broken down machine. Even if you can rapidly deploy it, who's going to crew it? MHW? Are they going to take all the safety risks with their blokes running someone else's patched up second hand machine? If not MHW, then who and where do these people come from at short notice?
It's unusual for mining (or any industrial operation actually) to have such redundancy in main plant items. You don't have large pieces of kit sat there "just in case", it's a very poor use of capital (and opex, as it still needs maintaining even if not used) and stuff left sitting tends to not work reliably when called up. If you want to cover your production commitments in case of a breakdown, there are other, more capital efficient ways of doing that.
No, I think the purchased HWM is very broken. Presumably they thought it would be cheaper than taking up the option of the second rig from MHW, but that's turned out not to be the case.
