RAG Chart, page-208

COD is an IOCG deposited they rely on assays for results/confirmation of what they SUSPECT is present at what percentages/if they are economic. Also IOCG deposits in SA are extremely deep, from memory a diamond drill probably gets 60-80m depth a shift.

RAG is a Ni-Cu deposit in which yes you can assay for grades however the type of sulphides which are drilled are indicative of grade - ie: you don't need assays to confirm a discovery - you essentially immediately know if what you have drilled is economic or not. RAG said in the discovery announcement that the hole is in progress so we can expect an announcement fairly soon as we don't have to wait months for assays for confirmation.

that's why people are bullish on RAG, not to mention the mineralisation looks like an analogue of sakatti (x3 bigger than nova/SIR).

to see what happens when IOCG hopefuls get their assays back and they are sub par despite having good visuals look at the chart of TAS or CHK - there's a good chance COD could go down the same path.
