Tele: price and duration?

Is running 14km normal to find a red mining spot? I am in Attensia (or something like that), maybe I should move to somewhere else?

First of all, you don't need red spot for mining. Red means you have more cycles inside one tile, not more ore per cycle. As long as you always have one ore tile prepared to switch to, if your tiles are empty you loose only 1 cycle when switching tiles. I never counted cycles, but if a yellow spot has only 50 cycles and red would have 100 cycles, you would loose 1% of ore due to switching tiles 2 times instead of 1 time per 100 cycles.

14km is far, but the usual miner tend to mine near of terminal, therefore near spots get cleared much faster than spots far away which leads to the feeling, that all spots are far away which is wrong if you consider every spot available in a year. The more miner are on same terminal located, the more likely you will have trouble finding  ore spot nearby.  But this clearly says, that there is no general rule to move from Terminal A to Terminal B as the more would follow the rule, the less benefit would remain until the point when its better to ignore that rule than following it. 

If I find no ore near terminal, I look around teleports that are easy to reach from Terminal.

OP, you may want to mosey on over to Tellesis where the majority of RAD's members are based. There's regular mining ops where you can learn the basics and hang out on teamspeak.
There's also an internal market which is steadily growing each day. If you would like to get involved with the corps production team contact either Khetar, Viirus or Lonwolf who can help you get set up.
