After the minerals are removed from the mine, the equipment will be sold for an estimated residual value of $60,000. The structures will be torn down. The mine is expected to produce 1,400,000 tons of ore. After the ore is removed, the land will revert back to the state of California. During 2021, Trevors extracted 210,000 tons of ore from the mine. What total amount would be charged to depletion of the mine and depreciation of the mining equipment and structures for 2021, assuming that Trevors uses the units-of-production method for both depletion and depreciation? (Round your final calculations to the nearest whole thousand dollars.)
