ASIC today released a public submission in response to  issues papers recently released by the ASX and the Joint Ore Reserves Committee  (JORC) on disclosure of mineral resources and ore reserves in which ASIC states  its position on the level of certainty required for the disclosure of production  targets.
The JORC Code provides a clear  framework within which the level of geological certainty about minerals  resources and ore reserves can be reported. The use of production targets in  fundraising, market announcements or control transactions, without sufficient  geological certainty having been established, can lead to the market being  misled.
While exploration targets and  inferred mineral resources under the JORC Code - as opposed to more certain  mineral resources and ore reserves - are important to disclose, they are too  uncertain to provide reasonable grounds for a production target or statement  implying economic viability, according to ASIC.
‘Ensuring market integrity means public disclosures by companies must  not be misleading,’ ASIC Deputy Chairman Belinda Gibson  said.
‘When companies make production  targets public, investors should be confident that they are based on reasonable  grounds and they are likely to be achieved. Where production targets are based  on an inferred mineral resource alone, the low level of geological certainty of  the resource means that an investor cannot rely on the  target.’

Background
The ASX released the ASX  Listing Rules Review Issues Paper: Reserves and Resources Disclosure Rules for  Mining and Oil & Gas Companies on 5 October 2011. The JORC released the 2011  JORC Code Review Issues Paper on 17 October 2011.
Under the JORC Code: 
- An inferred mineral resource is a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence: clause 20.
 - An exploration target is a statement that is conceptual in nature where there has been insufficient exploration to define mineral resources or ore reserves: clause 18.
