Mining Quests: Quick and easy skilling!!!

I don't know how many of you are unaware of the challenges available for miners. But, you can obtain them from an NPC at Cape Corinth. Iron, Lyst, Zinc are the three I can remember off the top of my head but there are a couple others available too. Blausriam is the fourth one I believe, and just maybe belkar is the fifth. Every so many points worth of mining claims you can collect free Prospecting or Mining skills. The rewards get sizeable as you progress, and yes, mining progresses very slowly if you are trying to skill up in it, so you might as well get yourself involved with these quests. Why leave free goodies on the table when they are for things you do anyways?

Lysterium: Rich deposits of lysterium are present on Atlantis Archipelago.
Belkar: I don't remember if it is a mining challenge or not but it is a daily challenge mineral, so, best bet for belkar is around wolverine hope.
Iron: North of Ithaca just avoid the troxies.
Zinc: This has been a tough one for me lately, when I go to find zinc I tend to come back with langotz, I know, what a compromise aint it. Well, best zinc lately is around new Switzerland in the LA. I stick to the one that doesn't have any mobs.
Blausariam: Indeed is one of the challenges. You can find it in abundance in the LA to the southwest of akmuul, and shinook river also carries it to some degree.
