OK, so using 50 tpd throughput, average 1.25 g/t au and 22 g/t ag, one gets $60/ton, or $3000/day. Rounding down for the considerations you mentioned, say $2800/day. I don't know what it costs them to keep the lights on, but it's got to be at least close to that.
So the key in the most recent new is, which of those samples gave the truest picture of what's in the piles? If it's (1) or (2), pull the plug and go home. If (3), they may make a go of it...
Hard work often pays off over time,
but laziness always pays off right now.
