Abstract

The paper discusses exploration estimate options by drilling holes from underground workings sunk by under- sized self-propelled machinery compared with drilling holes from surface. In terms of exploration costs, drilling holes from underground workings is a better option in upgrading potential resources to indicated reserves. Exploration cost per 1 t of metal increases insignificantly (from 2,3% to 2,5%) compared to its price, hower, exploration material quality improves, exploration periods decrease and it is possible to speed up transition to pilot works at the deposit.
