Loads of odds and ends, some has been sitting there for months, have a look, carrier links in sig, cargo is visible
It all depends on where I am as to what I bother to mine, at the moment I am in the Formorian Frontier so mainly only core type and Tritium but when I am back near the bubble or Colonia I will increase the range to most of the medium priced and those in demand on the mission boards.
3 main ways to sell and to work out what to mine, keep an eye on
INARA commodities prices it will give you a good guide as to what the stations are paying, on certain things you will also see what some other carriers are willing to pay, Bromellite is one of the interesting ones, you can get a lot better price at some carriers than at stations, the third option is the mission boards, this is where some of the previously mentioned carriers are selling to, if you can find the right stations and build up your rep to get top price or just sell to the carriers choice is yours.
