RE:RE:RE:SEA's worse NightmareGreat points Coyb88. So with a blockcave the entire mountain starts to cave in on itself and it fans out exponentially from the load site below. So how does one blockcave support a massive tunnel above, even if it's off to the side? Seabridge seems to be in need of an air suspension tramway or one long covered conveyor built. JMHO
