  Mining Methods Block Caving Geology For Investors

  Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs. If there is enough ore, initial capital will be recouped over the life of the deposit.
