    Block gravity caving is a bulk underground mining method which allows large low grade deposits to be mined underground This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted It is a useful technique to extend The surface pockets of cerussite were soon exhausted but the owners found that the orebody ran 23 copper with silver and gold as byproducts Most mines of that era could profitably mine ore containing 3 or 4 copper so the Copper Queen orebody was considered extraordinarily high grade
