No Les, it is correct as "Ore Shoot".
This is where the ore was dropped and workmen would take aim from around 30 feet with rifles and "shoot" the falling ore as it fell into the cart below. This saved a lot of time and energy resources with the crushing later and the addition of lead (from the bullets) also increased the net profitability of the yield.
I know you are a very well educated man and I suprised you didn't know that the miners worked in this way ?
