Well no, I was talking about where you sell the cargo. The rings where you mine and the market where you sell don’t have to be in the same system. I think boom state industrials have mining missions to hand out, and pay more for your product (the latter being more important).
When in Colonia mining metals, I just used the ring closest to Jaques Station. I think one pristine metallic is as good as another. Where to sell it is another question. I don’t think I got the best prices I could have, back then.
Lately, when I found a decent amount of Painite, it was worth picking the systems for the price they were paying for that commodity alone. One system might pay double or triple what another is paying. To know the current prices remotely, I had to have visited the local commodities markets – actually docked at the stations. Once you’ve been to a market, your ship effectively has a remote link and you can check current prices on the Galaxy Map. Change the mode to Commodities, and pick whatever’s worth most in your hold. Then go sell to whoever’s paying most.
I aim for Painite, Platinum, and Palladium. Along the way if I pick up some Samarium, Praseodymium, Gold, or Silver, that’s ok. I don’t pick up lesser metals than Silver. With the Ignore list set, the limpets won’t pick up unwanted fragments, and if any dross comes along with the good stuff, the hopper will automatically vent it.
BTW I can totally empathize with both the cost of nicely outfitting a Python, and the lackluster outfitting available at Colonia. It ain’t the Bubble, it’s a few small towns in the Wild West.
When I mined in Colonia, I had to use a Type-6. Couldn’t even properly outfit that!
