Quite. I not an expert at all, but the question "how do we bring it down" is better put "how do we bring it down safely and so that we can easily recover the material".
Throwing rocks down the gravity well is easy, keeping the velocity low at bottom end, or low enough plus aiming accurately at an empty spot, is hard.
