"So I supply my own pick and shovel and whatever gold I find you'll buy it off me at less than market value"

"And you own the site"
"Yep"
"And when I hit it big you turf me off and get your own goons in"
"Yep"
"I'd be an idiot to agree to that"
"Yep"
"But you own nearly all the prospecting sites, so I have little choice"
"Yep"
