^Identified resources: Specific, identified mineral deposits that may or may not be eva'uated as to extent and grade, and whose contained minerals 

 ™^y or may not be profitably recoverable with existing technology and economic conditions. 



* Reserves: Identified deposits from which minerals can be extracted profitably with existing technology and under present economic conditions. 



3 Conditional resources: Specific, identified mineral deposits whose contained minerals are not profitably recoverable with existing technology and 

 economic conditions. 



* Hypothetical resources: Undiscovered mineral deposits, whether of recoverable or subeconomic grade, that are geologically predictable as existing 

 in known districts. 



^Speculative resources: Undiscovered minerEl deposits, whether of recoverable or subeconomic grade, that may exist in unknown districts or in 

 unconventional form.
