I think you will find they have done all their numbers based on the core and the outcrop is cream:

"The results show similar yields for both Outcrop material (taken from the weathered zone) compared to Core taken from wells below the weathering zone. Outcrop material processes well compared with the Core material and should represent upside to the operation. Core material generally requires higher temperatures to achieve equivalent yields or a longer processing time.

Figure 3 below shows that the yields from the cannelite require longer processing times. Results show that the desired conversion of 30% is achievable and is largely unaffected by temperature for the Core, but the Outcrop materials were positively influenced by the increase in temperature towards 400oC at longer residence times."
