What will happen in the future with this scenario?

So, a couple of things.... First, it's easier and *cheaper* to find & mine gold here on Earth. Mars, according to the nebular theory of our solar system's formation, should have less than 1/3 the gold of Earth - not only would it be harder to find, but it's also going to be very much less than what's available on Earth.

Second, say you found a Fort Knox-sized deposit sitting on the surface - a million pounds of gold. The expense of going to, mining (even with robots), and returning to Earth is going to be prohibitively expensive - it's going to cost you, say, $75,000 per ounce, when gold on Earth can be mined & processed for $2,000 an ounce.

Third... say you *did* return the million pounds of gold - Bill Gates funded a mission to get it, and we got it... now, the price of gold is *slashed*, because it suddenly became more available - there's more gold, making it less precious, making the price fall - making your mission to Mars even more expensive because now, you can't pay for it in the gold retrieved....

For the next 40 it won't make any difference at all.

I once heard a comment that if the Apollo 11 crew landed on the moon and found large craters stacked full of gold bars - already smelted and ready to be carried away, it would cost more money in terms of fuel consumption to retrieve those gold bars and bring them home than the gold bars are actually worth. If the planet Mars was made of pure gold nobody would ever go there for the purpose of retrieving it or mining it because it would cost too much money. In order to make asteroid or Moon or Mars mining a reality something would have to be discovered that is exceedingly rare and valuable. For example gold or oil or uranium or whatever wouldn't be worth mining off world right now but as resources start to run dry and demand gets bigger the value would go up to the point where it may one day become economically viable.

In which case obviously there'd be a race to stake out claims just as there is with the resources under Antarctica -international agreement prohibits mining or other exploitation of Antarctica but countries are staking out their claims in the form of "scientific" research, and will continue to do "scientific " research until the resources become so scarce that international law allows the exploitation of this area in which case they will move in quickly and mine it as quickly as they can before anyone else gets a chance as they compete with each other over the resources.

Earth is a really big rock in space, Mars is only 10% the mass of Earth, Earth has way more gold than Mars does. The only advantage gold would have on Mars would be that the land is unclaimed and can not be claimed as sovereign by a country hence it's a free for all to anyone who can defend it.

Fundamentally, gold from Mars can not compete with gold from Earth in a market on Earth but it could compete in a market in space as it is expensive to launch anything from Earth. It would also be expensive to launch on Mars as there are no convenient launch bases with a support staff or factories making rockets but the lower gravity means it could be less expensive than Earth to launch from Mars.

When hydrostatic forces make an object into a sphere like Mars, it heats up the rocks till it melts and the heavier elements drift down at least into the mantle. It's only volcanic activity that brings a small amount of it back to the surface in veins. It would be the same case on Mars except Mars is less geologically active. It may be easier to retrieve gold from small asteroids where it hasn't sunk towards the center of a sphere.

As it currently stands, gold would have to trade at $518 million US an ounce for gold from space to break even, more so for gold from Mars because of the higher gravity compared with the asteroids. It's not going to happen any time soon and you're overestimating the value of mining in space. Plus the only market in space are a few astronauts at the ISS who left their credit cards n Earth.

Helium 3 would only be viable if fusion reactors becomes viable. We've spent trillions of dollars over how many decades with reactors that are several buildings to support and we still don't have a viable fusion reactor. Thorium would be a better pick than Helium 3, at least we know Thorium reactors work.

A discover of gold ore on Mars would only be confirmation of volcanic activity.

Helium 3 does exists on the moon in large quantities. H3 is far more valuable than gold can ever be.

There's just no cost effective or efficient way to collect the H3. So your situation is invalid. Countries would rather go to the moon for H3 rather than mars for gold.

Plus anyone with a basic understanding of Astronomy and how our solar system formed will know that the existence of gold on Mars is likely, how much is debatable. Our planet formed from the same elements that mars did. So yes, gold, more then likekly, does exist on Mars.

Those are good answers. Helium 3 is a gas so possibly a million one pound containers would be brought to Earth and offered for sale for $100,000 each. A few would be purchased but then there would be few and rare buyers. Some of the buyers would regret their purchase as presently there are few uses, and helium leaks very easily. There is a fair chance that helium 3 will never be developed for practical fusion, and the supply is limited to one million pounds, unless someone is willing to spend perhaps 50 billion dollars to find and bring another million pounds of Helium 3 to Earth.

A good educated guess would be it isn't going to happen since rovers have yet to be designed to find such resources.

Calm down that **** aint gonna happen
