What are you refering to? Everything mined in space has to come to where it is needed. Brring a space elevator, that requires shuttles that have to be rocketed into space, burning far more money than the ore is worth. And simply crashing it down will burn must of the orde, and cause all kinds of destruction on earth (and burn even more on impact). With SR technology, or real technology for that matter, space mining just isn't feasible at all.
-- There's no free lunch. Even the space elevator won't remove the energy cost to get into orbit -- it just lets you use energy sources that are FAR more convenient (like electricity).
-- Let's back up a bit:
* Space mining in Shadowrun is completely feasible from a technical standpoint. In fact, it's almost trivially easy in some respects as major parts of your infrastructure can be constructed at the harvest site without any expensive human intervention. If they so desired, the megacorps and other players have the know-how to build fusion drives, ion drives, plasma sails, and all sorts of things to move things around without breaking the bank on expensive and volatile chemical rockets.
* There appears to be no planetside demand for raw or refined space metals. The small-scale operations on the moon do not appear viable from an in-game economics standpoint if Earth is the market; you're moving extremely high bulk and very low cost materials up the moons gravity well and all the way down to Earth. Stuff doesn't "fall" from orbit orbit so you have to push it down there at great cost. It's possible they are building caerns (seriously, Immortals and Great Dragons have contingency plans too) but more likely what they mine is used on-site or for other orbital projects (as that is FAR cheaper than bringing it up from Earth).
--
Economical: Boosting refined metals into other orbits for construction. Moving cheap, high bulk metals around on Earth. Bringing high value-added manufactured goods down to Earth.
-- Not
Economical: Boosting anything into orbit (unless it's your only option/investment). Spending the delta-V and drop shielding to move most metals from space to Earth.
* Most of the pie-in-the-sky space development plans assume some form of resource shortage that makes this worth the trouble.
Shadowrun, as part of the invisible "a wizard did it" background that keeps things appropriately zany, doesn't have this ... yet. Which is rather remarkable given how the line has evolved to incorporate contemporary geopolitical events.

That is no naturally occurring orichalcum. It was hidden there in the 4th world. That is rather unlikely to happen in space.
-- Reference? This is not backed up by the in-game fluff or mechanics of
Year of the Comet.

Nope, it hasn't. But what is the point in looking for uranium in space to build power plants in space that are absolutly irrelevant to the planet which is supposed to benefit from them? And Fusion generates plenty of less radioactive materials, which fulfill all your medical needs (with essentially unlimited hydrogen supply by fusion power and hydrolysis, small scale nuclear power is unfeasible too compared to fuel cells).
-- Fusion plants in Shadowrun do appear to be very large, capital intensive design. This means they are probably not suited for mobile spacecraft - so compact fission plants may have a new lease on life above the gaiasphere. Very large stations like Z-O may have a fusion plant (I don't recall it being mentioned, but it's likely), as do surface installations on Mars and the Moon.

Yeah. I am more thinking of small objects that would be unknown since they are too small to be observed from earthspace. Those can be devastating to space ships too, since they tend to poke holes into them.
-- Anything large enough to damage the craft could be detected far in advanced and taken care of by course adjustments or zapping it with your housekeeping laser.
QUOTE
Which is why undersea mining is awesome.
-- Well, that has its own problems but you don't have a gravity shelf to work over.
QUOTE
The really nice thing, though, is you don't only have to mine the stuff, you also have to bring it back somehow. Even with a space elevator, that's an awesome lot of mass that needs pushing, and a ship that will be very vulnerable to impact from minor objects and thus, annihilation, loss of investment, and disaster fro the mining operation.
-- There is always a risk in these operations, but I think you are overstating the dangers of losing your assets from collisions. LEO is going to be FAR, FAR more dangerous an environment to operate in than the rather empty "asteroid belt" for example. Moving mass around is the hard part as you say, you can't just "drop" things down the gravity well despite the terminology
