Mining Institute Aims For Code On Diamonds
The Age
Monday August 30, 1993
The bull market for diamond explorers has prompted the Australian Institute of Mining and Metallurgy to investigate a reporting code for the industry.
A committee has been formed to devise a code to remove much of the uncertainty in the reporting of exploration results.
A code for the non-diamond sector of the mining industry _ the Australasian code for reporting of identified mineral resources and ore reserves _ has long been in use.
The cause of confusion in diamond exploration reports ranges from the loose use of kimberlite in describing rock types to the use of the terms micro-diamond (less than 0.4 millimetre) and macro-diamond (more than 0.4 millimetre).
Diamonds of either size are invaluable indicators in the diamond search. But unless a macro-diamond is about one millimetre, it will generally fall short of what might be called a commercial-sized stone.
