Can somebody who understands JORC standards help with this?
Munni Munni has a 2004 JORC resource of 2.2MoZ PGMs, primarily Palladium. I’m not sure when that was put together but presumably prior to the 2012 JORC code so let’s say 2010. In 2010 the price of Palladium was about a quarter of what it is today. Rhodium has moved far more significantly still.
Now, under the 2012 JORC code, the definition of a resource depends not just on what is there but on what is economic. That means it’s necessary to use a grade cut off, and what that is depends on the price of the metal in question. I don’t know whether this was also a feature of the 2004 JORC code, but it seems likely it was, ie that some cut off grade had to be used, which in turn would be influenced by metals prices.
So… does it follow that when we upgrade the Munni Munni resources to 2012 JORC we are going to get a massive load of “free” extra ounces just by virtue of prices having rocketed and cut off grades therefore being much lower?
