Depends on the scale of "going down". Many mines are in the mountains and the material has to be brought down to lower elevations. The mine entry may be lower than the nearest pass but still a lot higher than the destination of the ore.
Open pit is much more common for this type of equipment and it’s basically a reverse mountain. Still might be enough regenerative braking from just the weight of the truck though.
An open pit at an elevation of 1.5km still means the bottom of the pit could be 1km higher than the place the ore is processed at
In that case no, because it'd be bringing the weight of the truck and the ore with it.
