The moon's gravity is pretty minor compaired to Earth's. So we use a mechanized lunar base to create solar cells out of the silicon dioxide on the lunar crust and place them in protective cases. Then we use a mass driver or similar device to send them into Low Earth Orbit for use on space stations or other large projects. They could then also be brought back to earch during routine restocking missions to the ISS. This sort of think also might enable us to build space stations on the stable Lagrange points (which would facilitate getting people to a lunar or martian landing points).
In essence, I would see the real potential not for mere mining (who wants to pay billions of dollars for gravel anyway, or even Platinum for that matter) but rather for manufacturing centers.

It amazes me that so many allegedly "educated" people have fallen so quickly and so hard for a fraudulent fabrication of such laughable proportions. The very idea that a gigantic ball of rock happens to orbit our planet, showing itself in neat, four-week cycles -- with the same side facing us all the time -- is ludicrous. Furthermore, it is an insult to common sense and a damnable affront to intellectual honesty and integrity. That people actually believe it is evidence that the liberals have wrested the last vestiges of control of our public school system from decent, God-fearing Americans (as if any further evidence was needed! Daddy's Roommate? God Almighty!)
Documentaries such as Enemy of the State have accurately portrayed the elaborate, byzantine network of surveillance satellites that the liberals have sent into space to spy on law-abiding Americans. Equipped with technology developed by Handgun Control, Inc., these satellites have the ability to detect firearms from hundreds of kilometers up. That's right, neighbors .. the next time you're out in the backyard exercising your Second Amendment rights, the liberals will see it! These satellites are sensitive enough to tell the difference between a Colt .45 and a .38 Special! And when they detect you with a firearm, their computers cross-reference the address to figure out your name, and then an enormous database housed at Berkeley is updated with information about you.
Of course, this all works fine during the day, but what about at night? Even the liberals can't control the rotation of the Earth to prevent nightfall from setting in (only Joshua was able to ask for that particular favor!) That's where the "moon" comes in. Powered by nuclear reactors, the "moon" is nothing more than an enormous balloon, emitting trillions of candlepower of gun-revealing light. Piloted by key members of the liberal community, the "moon" is strategically moved across the country, pointing out those who dare to make use of their God-given rights at night!
Yes, I know this probably sounds paranoid and preposterous, but consider this. Despite what the revisionist historians tell you, there is no mention of the "moon" anywhere in literature or historical documents -- anywhere -- before 1950. That is when it was initially launched. When President Josef Kennedy, at the State of the Union address, proclaimed "We choose to go to the moon", he may as well have said "We choose to go to the weather balloon." The subsequent faking of a "moon" landing on national TV was the first step in a long history of the erosion of our constitutional rights by leftists in this country. No longer can we hide from our government when the sun goes down.

Let's clarify: The universe does not exist for a reason. It simply exists.

It'll probably be a centuries before we get out of this rinky-dink solar system. We've got to get busy putting people on the moon, on mars, on io, on europa, on venus. We've got asteroids to turn into space stations.
And don't be a pussy about limited resources. Eventually, our sun will go red giant and fry all the inner planets to a crisp. That means all these precious resources have a built-in shelf-life already, no matter what we do.
By then, we had better be somewhere else. If we have to suck all the gas out of Jupiter to give us the juice to do that, then so be it.

Commercially, the moon is a cheap source of materials needed for large-scale construction in space. Oxygen and aluminum are readily-available propellants. Aluminum is a good structural material, particularly in the moon's weaker gravity. Solar panels and reflectors can provide cheap heat and electricity. Metals can be refinend and oxygen extracted by melting lunar soil, capturing the escaping gases, and allowing the result to separate as it cools. The moon's atmosphere is almost nonexistent, providing a free vacuum several orders of magnitude better than the best commercial installations, and the thin atmosphere is very clean, virtually free of dust above one to two meters above the surface.
The ability to cheaply manufacture and launch satellites, probes, and other vehicles means direct observation of planets, asteroids, and comets could be conducted many times more frequently. The moon, while it lacks the earth's large shock-absorbing core, is a geologically quiet base upon which to build a massive telescope or array, with the entire mass of the moon insulating it from the sun's radiation, and virtually no atmosphere to distort the image. Even the mere fact of having scientists in long-term direct contact with another solar body will enormously expand our knowledge of the universe. Studying the earth, we can only hope other places are similar, but studying the moon as well means we can make generalizations with much more confidence.
I don't think any one company is rich enough to set up the infrastructure needed to be sustainable and commercially successful, and no government can dump that much money into a project with no short-term returns. We can only hope that several companies can cooperate either on one project or will develop complementary projects. If several groups are planning on trying to setup installations on the moon, it might be profitable for another organization to setup an installation whose sole purpose is to provide materials the others will need. A small automated facility which extracts oxygen from the soil could save a dozen other installations the expense of setting up their own oxygen plant. Another installation could extract only aluminum and sell that for construction of its neighbors, perhaps paying for its oxygen consumption in aluminum used to expand the oxygen extraction facility.
I'll be the first to admit this sort of closed economy cannot sustain itself and must eventually reap some financial reward for the companies on earth, but cooperation between enterprises makes everyone's barrier to entry that much lower. As soon as the infrastructure is setup to mine and use materials from the moon, construction there should be immediately financially rewarding and should create a scientific and manufacturing boom. Once we reach that point, it's all downhill from there. The problem is the financial risk involved in getting to that point. Hopefully the lure of potentially vast riches will bring in the necessary funding.

Ice from Earth's South Pole would work fine as a source of hydrogen and oxygen to fill the tanks of a Mars ship, except for one little detail - YOU'VE GOT TO GET THE ice/oxygen/hydrogen FROM EARTH'S SOUTH POLE TO THE ORBITING MARS SHIP. This means fighting 1G gravity PLUS a thick atmosphere to get every pound of Mars fuel in orbit. Move the ice/oxygen/hydrogen from the MOON'S south pole and you ony have to fight 0.18 G gravity and no atmosphere to get it to the orbiting Mars ship.
The energy required to do these two tasks doesn't scale linearly - it isn't six times easier to lift off from the moon because it has one-sixth the gravity of Earth. It is a LOT more than 6 times easier to get a pound off the moon than a pound off of the Earth. That's why a Saturn 5 was 365 feet tall and a lunar module was only 20 feet tall. (Well, yeah, I know the Saturn 5 had to lift more weight than the LM, but I'm going for mental illustration here. There is no such thing as a 20 foot high rocket that can lift ANY amount of weight from Earth to orbit, not even a few ounces...)
So the final point remains, if you're going to mine something from the moon, your best bet is not to bring it to Earth but to take it to some orbiting launch site and use it to go somewhere else like Mars. Being on the moon puts something a lot closer to being available for use in space than being on Earth does.

This is true, but only if we could just go there and pick it up lying around. However, as the article points out, there is no volcanic activity to concentrate metals in veins, and no erosion to break it up into convenient nuggets to find. So, you're going to have to mine it, and you'd have to process a huge amount of material at that because you aren't going to find many rich veins.
This means mining machinery. During the last
A small crushing machine [equipmentcentral.com] weighs over thirty english tons. Granted if you were to make a machine to be transported via spacecraft, you would do everything you could to make it lighter. However, we are talking about crushing rocks here; cleverly reinforced tinfoil and carbon fiber are not going to do the job. You'd also have to pack a fairly powerful nuclear reactor, since even this small machine requires well over a hundred kilowatts to operate. This means the reactor would have to be packed to survive launch accidents. Cassini's RTGs, for example, provide well less than a thousand watts when they are fresh. Some Russian designs for space flight produce 5-6KW, still an order of magnitude too small to run a small crusher. You would need much larger reactors, properly shielded and packaged to survive launch accidents.
Furthermore, this example machine is a small machine, and the lack of volcanically concentrated ore veins means you have to have a machine with a lot of capacity. It would be just barely feasible to put one of these small machines on the moon with a Saturn V (6.1 million pounds to deliver about 45 english tons of payload to lunar orbit).
I don't want to be a wet blanket here. The point is that mineral wealth does not seem to me at this time a sufficient reason to go to the moon (although these people may have found clever ways around these obvious objections, and all bets are off if we look outside the next twenty years or so). It seems to me at this time only commodities which are lighter and more precious than metals can justify the cost -- things like knowledge, and prestige.
If somebody was going to put a research station onto the moon to use its unique environmental properties (moderate gravity, hard vacuum in large quantities) I would be less skeptical. I'd be even less skeptical of a scheme to put super rich tourists on the moon, or if a single ultra wealthy individual like Bill Gates announced he was going to spend his fortune on a visit to a moon.

Actually, the surface of the moon is already covered with lunar material that has been broken up for you: it's called "dust." Smashed up by millennia of impacts from meteors, asteroids, and the like. Look anywhere on the moon and you will find many tons of it. I'm not sure what the depth is, though, and it may vary.

I'm very skeptical of the person from ASR making proclamations about the geological details of the moon. Experts get paid to voice opinions, but the truth is that we've literally only scratched the surface of the moon. We know some facts from the observations of the astronauts and the samples they brought back. But the astronauts didn't go everywhere, and they didn't get to concentrate on anything for very long. What we did find ruined a great many of the existing theories about the moon, and it seems likely that there are just as many bombshells up there remaining to be discovered. All we have right now are theories, based on a very incomplete sampling of facts.
One other big point you're missing is that the minerals and raw materials mined on the moon would have a far greater value in Earth orbit than they would on earth. In orbit, the $10,000 per pound you mentioned is ADDED to their value. How much would NASA pay for aluminum girders and panels that are already AT ISS? Sending them to Earth orbit from the moon is also far cheaper than returning them all the way to Earth.
There are also far less environmental problems with mining the moon. By any reasonable definition, the moon doesn't HAVE an environment to spoil. On the Earth, there are profound cleanup-related issues that are only now beginning to be reflected in the costs of things.
I will say that as far as the amount of legal objections you have to put up with goes, mining on the moon could be as bad as mining on Earth. I'm sure the far left will come up with some reason to sue endlessly.

It's an interesting point, but I suspect that the cost of fabricating hardware is going to be much higher on the moon than the cost of launching earthmade hardware, until the initial cost of the lunar facilities has been amortized over LOTS of orbital projects. In other words, to help build a relatively small project in Earth orbit, you'd have to build a much larger and more complex project on the moon first -- it just isn't an immediate help. However, if you were building a VERY large orbital structure or a large number of structures then lunar or asteroid mining might be a sensible option to pursue.
I will say that as far as the amount of legal objections you have to put up with goes, mining on the moon could be as bad as mining on Earth. I'm sure the far left will come up with some reason to sue endlessly.
Left-bashing aside, I think you overestimate the mining company's political clout. They can pretty much come in, liquidate an area, take their profits and disband before they can be held to account for any damage. On the other hand, getting the amount of nuclear fuel to the moon you'd need to power a major mining operation would be a huge political and legal mess.
In any case, it's not that I don't want it to happen; I just think its very unlikely.

No offense, but it seems to me your numbers are at best somewhat suspect. : (
Wrong, since the dust is already ground up finely, most of the work is already done. The next stage might be to sift, maybe separate magnetically, and then to heat up batches of the dust and melt out the metals. Not a lot of machinery needed. And, you have lots of free solar energy to work with, assuming you base near the poles, so that you can gather solar energy all the time. Particularly good when you just need to melt stuff: you can focus the sun on it using big mylar mirrors.
As I pointed out before, mankind has spent a total of, what, a week and a half on the moon, in scattered areas, getting at best an initial sampling of data. We don't KNOW whether minerals are concentrated anywhere on the moon or not. Detailed surveys have not been done yet.
You suspect, but do you have numbers?
Fabricating parts remotely is getting very easy to do, if you use 3D printing/sintering technology. They're used in rapid prototyping now. They can literally print out a metal part one layer at a time, with very good tolerances. This is a machine the size of an office photocopier. Sending one to the moon would be very feasible. They require metallic powder to work with, which is coincidentally what you might expect to get out of your dust-mining operations.
Building electronics would be more difficult, but you would have lots of good clean vacuum and power, and raw materials.
I am sure, though, that there would be dividing line at which it would be cheaper to ship some components from Earth than manufacture them locally. If it's only some parts, though, and they're electronics and gaskets, you could carry lots of them for not too much weight.
Would it actually be commercially feasible? I honestly don't know. I admit I want to see it tried, though, because I'm a hopeless space fanatic. One thing is certain: it IS getting easier all the time.
Firstly, most of your power could be solar, if you're close enough to the poles to have power plants in sunlight all the time. Secondly, one of the major promising finds on the moon is large amounts of Helium-3 in the lunar dust and everywhere else, which may prove to be an excellent nuclear fuel. There is still a lot of research on fusion power that needs to be done on that, I admit, and there is a possiblity that it might not come to fruition in our lifetimes, but it is promising.
Let me say I respect the fact that you're trying to stick to facts. But, there is a lot of work that has been done on this subject, much of which is very encouraging. I'm sorry I don't have links at hand, but you might check in on the sci.space newsgroups to find more detailed info.

On the third hand (if you are a fan of The Mote in God's Eye) why mess with the moon, which has just enough gravity to be a nuisance, when there are all those asteroids out there? Some of them seem to be made primarily of iron-nickel (alloy steel) just waiting for someone to pull up with a big mirror to melt them and a set of molds to cast them into useful shapes. Or alternately, melt the whole asteroid, stick a very long blow-pipe up the middle, and blow it up into a big hollow sphere like blowing a glass bottle.
Of course, you've got to think really, really big. Maybe even bigger than the Reagan-Bush budget deficits....
Maglev will help here (Score:2)
You shoot maglev-ramp-building robots to the moon, they build the return ramp on the moon and you've handled the transport cost issue. The maglev ramp on the moon is used to fling the ore back at us ala Heinlein's "The Moon is a Harsh Mistress."
The biggest problem with mining the moon will be pollution. Just because the mining is happening on the moon won't mean we'll end up with no pollution here. The stuff is coming at us at a high speed and has to be decelerated without ablating into the atmosphere or cratering somewhere. If it ablates, you end up filling the atmosphere with ore dust. So somehow, the ore has to be gently brought back to earth.
Re:Maglev will help here (Score:2)
But consider, if the first 3k is "free" in terms of mass, then it takes a much smaller rocket to get the same amount of material into orbit.
Flinging robots with maglev is easier simply because you don't need as long an acceleration ramp - they can stand much higher g-loads than we can.

The Artemis Project [asi.org] is more of a space club than a business (although it has some of the latter, and it is pretty successful compared with other clubs). Their web site contains a Data Book which was pretty good, but seems to now be members-only. Another good site is P.E.R.M.A.N.E.N.T. [permanent.com] with lots of details about things like all the different minerals on the moon. Much of it is kind of long term (for example, mining applications which only make financial sense if you are using the minerals off-earth). And at the risk of immodesty I have pages on mining [panix.com] and novelties [panix.com] (with the former being more for the intrinsic value, such as platinum for its appearance or chemical properties, and the latter more having value by virtue of being from the moon). My pages are more focused on near-term applications (such as bring platinum group metals to earth). I try to include some numbers (such as prices of platinum, how much flooding the market would affect the price, how much it would cost to get materials back from an asteroid and stuff), so that you can tweaks the assumptions and see how that affects the finances.

Notice that key biogenic substances including hydrogen, carbon, and nitrogen do not make up a segnifagent portion of moon rock. (~50ppm)
In addition the moon posses Helium-3 (10ppm) - an isotope otherwise nonexistent in the inner solar system. It is a key substance for magnetic fusion with the reaction D + He3 -> He4 + H1, which produces about 18MeV of energy (and does not produce the nutron bombardment of the D + T -> He4 + n reaction used in current experimental fusion devices). If fusion power generation becomes reliable in near future, He3 is worth at least $1 million per kilo at today's energy prices. Unfourtantly with the ~$10,000 per kilo launch price today, it would cost almost $5 billion to extract $1 millon of He3 and return the product to earch.
Until launch prices drop to about $100 per kilo, moon mining is pointless. Launch prices this low are possible, though it means working around the gridlock of the Lockheed-Boeing-JPL-NASA-Congress monster in the US (who's launch costs are ~$10000/kilo on a delta III and twice that on the shuttle).

Sorry about the pun above... The real trick if mining companies want to make lunar mining worthwhile is to make the cost of sending stuff to and from space. Chemical rocket propulsion is so horribly inefficient for that purpose as to be impractical.
Now a real place that it would be worthwhile to do commercial mining if transporting stuff could be made easier would be Mercury; that planet's supposed to be full of the dense platinum group metals as it's closest to the center of the solar system (guess that would qualify as a "Rich" world in Master of Orion terms, unfortunately it also qualifies as a "Radiated" world).

Moon mining is immoral (Score:3, Interesting)
Strip-mining will be the preferred and obvious method. In fact, casting debris off in any direction as a method of disposal will most certainly occur. The obvious results will be that the appearance of the moon will change. It will not take long for that to happen either.
The surface changes would end up being very geometric in the sense that it would likely be in shapes based in straight lines and regular curvatures. From an Earth's eye perspective, the moon would end up looking more like the "Death Star" instead of the celestial body of romantic inspiration if has been since the dawn of man.
ANY change to the moon's surface will be a change for the worse. The moon as it is in its present form has been an object of romance, wonder and mystery. It has been the inspiration for so much of our world's culture and development. It's literally a part of our humanity. Now people are preparing to exploit one of the most significant objects in human history for a few bucks??? No. We don't need the moon's resources to badly.
I think it should be prevented.

The Angular Resolution of the human eye is roughtly 1 arcminute. The moon is about 200k miles away at any given time. Thus, the smallest point one could see on the moons surface with the naked eye would be a completely black circle 58 miles in diameter on a white background. Since the stuff youre digging up is going to be the same color as the moon, chances are, you wont notice any difference. Even on earth strip mines dont get to be 58 miles in diameter.
