I found one nice planet Thunawanuro in the starting cluster when you first get control of the Normandy and when your heading to Omega. It has 6 very rich spots.
Also in the same cluster there was one planet, where I found a hidden mission but it wasnt known as an anomaly, its a Rhakni base but I am assuming its open if you helped the Queen in ME1, must be a bug in the game perhaps it should have been an anomaly. I wont say what planet, but if im correct a new start in ME2 from scratch it may not be there, I only found it by accident by misclicking when scanning for minerals.
So if you found anymore planets with Element Zero and other planets with hidden missions, lets list them
EDIT: I will give a hint on the planet with the hidden mission, its the only one even after mass mineral collecting it always stays Rich. I dont want to say the name incase people wont to find it themselves as a bit of fun.

If you find a planet which has scan results of Rich, you have a huge chance of 5+ very rich veins on the planet, each time you find more and more the scan result will drop.
So in order Rich > Good > Moderate > Poor.
Each time it drops it means less and less chance of a rich vein being found. This drop does happen while planting probes. So if they come across a planet that starts poor they shouldnt waste time looking.
I am sure the placements of the actual veins is random, but I think planet quality is pre-determined and is static at start of each new game.

All of the planets have a different percentage on what type of mineral deposit you will find, Iridium, Palladuim, Platnium. For instance on an ocean planet you will have a 70% change of finding platnium, 15% chance of finding Palladium and a 15% change of finding Iridium
So it did affect ME2. No doubt she will appear in ME3, and perhaps become an ally against the Reapers. Who knows :P
