Edit: I guess this thread is more about the incompatibility of iridium in Infinity than about where to find it. But I'll leave my post here anyways.
I quarried hundreds if not a thousand chunks in Infinity (many long hours of quarrying), and I got exactly one Iridium Ore.
I flew around in the Nether for a few hours and found a Nether Iridium Ore block. I think that was incredibly lucky and probably doesn't represent any kind of "average" rate that you can find them, but facts are facts. I think you can get six Iridium Ores from one Nether Iridium block after processing.
And then yesterday I flew around the Overworld looking for a Jungle Biome... along the way I came across three chests sitting on the Obsidian "shrines" (not sure what mod they are from, I think it's Thaumcraft?), and out of those 3 chests I got FIVE Iridium ores. Each chest had at least one Iridium in it.
So if you want Iridium Ore, my suggestion is to fly around the Overworld and look for those Obsidian Shrines with the wood chest in the middle. Those are probably your best place to find "mass quantities" (lol), based on my limited experience with Infinity.
