Comments on the geologic information

  • THE KIRUNA IRON DEPOSITS ARE THOUGHT TO HAVE FORMED BY A PROCESS OF CHEMICAL SEDIMENTATION, HAVING BEEN LAID DOWN ON A SYENITE PROPHYRY THAT NOW CONSTITUTES THE FOOTWALL ROCK. FOLLOWING DEPOSITION OF THE IRON ORE, RENEWED VOLCANIC ACTIVITY RESULTED IN DEPOSITION OF THE QUARTZ-PORPHYRY HANGINGWALL ROCKS.

Comments on other economic factors

  • IN THIS REPORT THE CAPACITIES LISTED ARE BASED ON AN ANNUAL CAPACITY OF 22,000,000 METRIC TONNES. THIS PROPERTY IS EXPECTED TO REACH THIS MAXIMUM ANNUAL TONNAGE BY THE YEAR 1989 AND CONTINUE AT THIS RATE UNTIL 2045. CURRENTLY PRODUCTION HAS BEEN IN THE 10-18 MILLION METRIC TON RANGE. PRIOR TO THIS, THE ANNUAL PRODUCTION WAS AS HIGH AS 26.7 MILLION METRIC TONNES FOR THE YEAR 1974.
