That would be computationally much more difficult and could completely fail in certain rare cases (think Mystcraft void age).
 
For further tests, if what was said about ore spawning is true, one should test with mystcraft world, flat.

Flat worlds are very high ones too, so it maximizes the ore spawning, and if no caves are chosen as symbols, it should definitely be accurate.

But yeah, it is definitely a low chance to stumble upon one of such ores, and the only "reliable" way to produce iridium is through mass/matter fabricator, depending on the pack. UU matter has a secret recipe for iridium, so go over the IC2 wiki to learn more about that, maybe?
 
You will save a lot more time using a massfab/matterfab to get it no matter how slow it is it will be a lot faster than mining the stuff.
Even if you found 1 an iridium plate needs 4 of them I think so what good would it do ya?

This is true, but remember that matter fabricators require at least 1 iridium plate, which costs 4 iridium each.
 
I've been running a BC quarry in 64/64 areas. In 4 runs of it I've gotten 4 iridium so it definitely SEEMS rarer than 1 per 5 chunks. I'm not worried as I got what I needed from uu matter.
 
I honestly thought that because the ground was so low, all the iridium spawning would have to be in that available space. :p I didn't know ore generation could even select air as a spawning location. Instead I thought that it would only randomize a piece of smooth stone in the chunk, not check any random block in the chunk if it was actually stone or not.


No, it will generate random place anywhere in a chunk in given height range and then put the ore only if there is stone (and probably marble) there. If it can't put ore, it will just skip it.
