US Survival. I just checked my HQ quarry, which has been upgraded twice, and it appears as though it went from producing HQ ore and stone to just producing metal ore, and I mean a lot of it. I have three large boxes jpiped from the quarry tumbler, and metal ore was not added to the filter, so it filled up and stopped. I believe the tumbler filled up with metal ore rather quickly, as the low grade was barely touched. Attached imaged shows crazy amount of metal ore in the tumbler.
