Actually, not a lot of "ifs", just two. The first "if" was assuming a figure for the flotation rate, and the one I used was lowball, less than half of the announced "optimal" rate. We know what the grades of the piles are because the assays have been published. So if (one if) they get any performance of the flotation unit that's reasonably close to what's been announced, they can generate at least enough to keep afloat, hopefully more. The other "if" was a bit more iffy- getting ore out of the Sinker. It's almost a sure bet that anything out of the veins in the Sinker will be much higher grade than the waste ore they are now processing. So "if" they can bring the Sinker up to code and get out the amount of new ore they are allowed under the exploration permit, then they are even better off.

BTW, as far as smelting the flotation product as opposed to treating it with the leach system- Yes, the leach system will work better, especially at getting out the silver, and produce a product that is essentially pure metal that just has to be melted into bars. But they can smelt the flotation product. If you've seen the pictures here, you know that they can produce at least a bar weighing a couple hundred ounces in one smelt. And while that bar may be only 20-40% gold, that's still not bad for a day, or even a couple hours of work. I'm not sure how much prep went into that smelt, but if they can do even one a week like that it will make the mill operation more than profitable.
