uranium at balama, page-14

What I found odd when I first compared the pair of maps was..

1) not only hd the "legend" changed, but

2) I found it odd that the Helio Resources map was "brightly coloured" to reflect the different ppm uranium readings, whereas the Jacana map was "fuzzy" like it had been in a snow storm resulting in many of the stronger "ppm" (black) readings not being clearly identifiable. Companies usually want to present these "anomalies" in full colour don't they? Certainly the other maps in the report are. Is there a reason for this that I don't understand?

This is the Helio map - go to the Jacana report page 34 for the comparison I refer to above.
