Monazite is denser than Xenotime and usually is more likely to contain higher HRE levels than Xenotime. Monazite is also more likely to be higher in Thorium.
None of this means it is a certainty with CUX, it's just from general world wide trends.
Monazite being heavier will always be easier to recovery by gravity,the SG difference is not high but it is enough to say the monazite is easier to recover. It is also a little harder which makes it more likely to exist in larger particles than the xenotime, again making recovery easier. These are generalisations but you get the idea.
If the gollywogs are able to pinpoint the areas where xenotime or monazite are respectively more prevalent then selective mining for higher proportions of certain REO's may be feasible.
It would be interesting for CUX to get some speciation work done to determine relative metal proportions in each of the minerals. That's not cheap and probably something for a bit later down the track. They'll be able to get trends indicating compositions anyway as they progress the met lab work that is currently producing con samples.
I like to look at these things for professional curiousity, don't take it as any great indicator that I'm keen. As I've repeatedly said, I'm a long way from convinced here.
If I buy in you'll see it in the disclosure.
