In general terms, "profit" is the loose change jingling around in your pocket at the end of the day.
Nano GOLD may run up to 3 troy ounces per ton. For convenience, let's say one short ton = one cubic yard.
Generally, "Profit" equals what we made minus what we spent.
Given a five cubic yard per hour operation;
"What we made" could equal 5 x 3 x 10 hours = 150 troy ounces of GOLD. (per day).
"What we spent" could be fifty sluices at $1000 each = $50,000 + fuel, labor, taxes, commissions and fees.
Do the math!
