Well this is true, if you are a low level and want mage xp, it works and you mage a decent profit and you get mining xp along with smithing xp. About the RUmmington mines, The competition is very feirce there between skillers, and I prefer the calm and scorpion infested mine of Al Kharid. Its a personal choice, but as I bank my ores(I'm reallypoor right now)Al Kharid works best for me.
