Yes - seems like a ridiculous operation to me, especially in a high wage cost country such as Canada, they only need the price of copper or the price of fuel to go the wrong way, and they have one of the largest most expensive loss making road base quarries in the world, there isn't even a decent moderate grade portion of the orebody that they could "high grade" until copper prices improve, so they have no plan B at all if commodity prices or other events go against them unexpectedly.

Wafer thin margins!
