Subject category Comment text
Deposit 75 SEE ADDITIONAL COMMENTS ON ATTACHED SHEETS THE NATURE OF THE DEPOSIT MAKES IT AMENABLE TO BOTH OPEN PIT AND UNDERGROUND MINING. (ROSKILL INFO. 1990). SINCE THE START UP OF PRODUCTION, ULUDAG HAS NOT OPERATED AT ANYWHERE NEAR CAPACITY. PROBLEMS WITH EQUIPMENT AND INCLEMENT WEATHER HAVE SERVED TO HAMPER OPERATIONS. (ROSKILL INFO. 1990).
