1000 tons of Te would only be a fraction of what's brought back by a realistic mining operation. Don't you also want all the platinum and palladium and gold hiding out there? Don't you want the iron for building space habitats? No, we'll bring back as much as we can manage, whether it's availability or transport logistics or fear of attacks that turns out to be the limiting factor.
1000 tons is how much Te is mined each year on Earth.
Global annual production of platinum is 180 tons.
