DavBr0 - looking at the other operations, Minto is the only Canadian asset in Capstone's p/f. They have a development play in S America, and two producing mines (Pinto and Cozamin) in Mexico and Arizona. The latter two are bigger than Minto and have lower costs, so have quite rightly been the focus of attention of Capstone. That in turn means that Minto has suffered from being the ugly duckling, it's been starved of finance, the best people have been moved to the core assets, and they've just done enough additional drilling to let it limp on from year to year. [It has only 20% of the M&I resource currently converted to Reserve ore, looks like Capstone basically drill enough to give it a few years at a time).
This 'just in time' style of drilling is what you'd do if you owned a mine and didn't need to raise finance for it - you've got it, so why drill out more than you need at any time? Whereas if of course this was a new asset and they were looking to raise the capex for a new plant, they'd have had to drill it out more. That's one reason the '4 year mine life' bit is misleading, when you're in this sort of situation you just do it as you go along, so there's never a point when you appear to have a long LOM.
I think that covers both of your questions in one - Minto is the smallest and highest cost of Capstone's assets and they've exacerbated the problem by not investing in it (as it's the smallest and highest cost ... you get my point).
