I've just rewatched Captain America: The First Avenger, and in the scene where he chooses his shield, Howard Stark tells him that all the vibranium they have is what is in his shield:

So in Age of Ultron, how did Klaw come into possession of so much vibranium? When you look at what Ultron made with it, it seems there were several tons of this stuff.

Klaw had it because he stole it from Wakanda, the source of Vibranium.

In the comics, Vibranium comes from the fictional nation of Wakanda. The name Wakanda has briefly appeared on screen in a few places, but is not really explained until Age of Ultron.

The thief brand on Klaw's neck is from Wakandan culture, and Tony explains that Wakanda is the source of Vibranium. All the Vibranium which Howard Stark obtained is being used in Captain America's shield. In The First Avenger, his exact line is

That's the rarest metal on Earth. What you're holding there? That's all we got.

Here "we" means the Americans and/or the SSR, not the planet in general. The implication is that Stark sent an expedition to Wakanda to retrieve it, and in the tie-in comic Captain America: First Vengeance, he describes it as “Stark Industries researchers”.

Since Klaw is a thief, and it's suggested that he escaped from Wakanda, it seems reasonable to assume that he stole it when he escaped, and it selling it on the black market. It's rare enough in the outside world that it would command a huge price. (I think the film mentions billions.)

How he smuggled such a large amount is unclear. The brand on his neck means “thief, in a much less friendly way”, and Tony says that he talked about “something new, a game changer”. It could be that his game changer is mass exports of Vibranium out of Wakanda, and he’s been thrown out as a result of his interactions with the outside world.

Marvel are planning a film about Black Panther, a character from Wakanda, so we may well find out more about Klaw's back story and the Wakandan supply of Vibranium in that film.

    I do remember a brief exchange between Captain America and Tony about Wakanda and something. Ugh, I can't remember it! I'll have to watch it again. Something about "I thought he got it all".

    @alexwlchan Probably worth mentioning that Avengers: Age of Ultron isn't the first Marvel Studios film to reference Wakana - I'm fairly certain it appears on a visual list of INSIGHT carrier targets in Captain America: The Winter Solider. Commented May 7, 2015 at 15:21
  • @DrRDizzle: True, but those 'background' references aren't really intended to be caught by mainstream audiences. They're for...people like us to search for and geek out about. They're hints and clues, but not really 'references' in the traditional sense.

    @DrRDizzle According to Google, it appears on a computer screen in Iron Man 2, but I can't make it out, even in HD screencaps. I’ve amended the incorrect sentence.

TL;DR: If like the comics, there is an entire mountain range full of Vibranium in Africa.

Although we have yet to see where Vibranium comes from in the MCU, Howard Stark described it as "the rarest metal on earth". Here is the dialogue from Captain America: The First Avenger:

STEVE: What about this one?

HOWARD: No, no that's just a prototype.

STEVE: What's it made of?

HOWARD: Vibranium. It's stronger than steel, and a third of the weight. It's completely vibration absorbent.

STEVE: How come it's not standard issue?

HOWARD: That's the rarest metal on Earth. What you're holding there - That's all we got.

However, if they stick to the comics origin for Vibranium, it can only be found in the African nation of Wakanda. In both the 616 and Ultimate continuities, pure Vibranium is mined from the central mountain range of Wakanda, which in actuality is a gigantic meteor that landed on the Earth millions of years ago... perhaps even the one that killed the dinosaurs.

enter image description here

The Wakandan mountains are the central feature of the tiny nation, and the Wakandan capital - usually referred to as Wakanda City - is built within the center of the mountains. Given the near-indestructible nature of the Vibranium within the mountains, this has allowed Wakanda to survive numerous conquest attempts by its many neighbors and/or outside forces.

enter image description here

Furthermore, the Wakandans have built their culture around the mining & use of Vibranium, allowing their primitive nation to flourish into one of the most technologically advanced places on Earth. Those few invading armies that made it past the mountains have found an army equipped with Vibranium-tipped spears & arrows, buildings made of Vibranium-laced stone, and a king wearing Vibranium mesh armor.

enter image description here

Within the comics continuity, Ulysses Klaw is one of the few individuals who managed to infiltrate Wakanda and steal Vibranium. Although he was caught & branded on at least on attempt, this has made him a fortune selling the metal on the black market. He is considered to be one of the world's foremost experts on Vibranium, and one of the only sources outside of Wakanda itself.

In Avengers: Age of Ultron, Ultron pays a visit to

a mining operation in Africa, which is being run by Klaw (Klau in the MCU). Klaw shows Ultron his hidden cache of Vibranium, which Ultron purchases for several billion dollars (right before losing his temper and cutting off Klaw's arm). Where Ultron got the money is anyone's guess, but he likely either stole it from bank accounts around the world, or simply told the bank's computers that Klaw's account had that much in it (with no actual money moving around). Either way, the result is the same.

This scene would seem to confirm that the MCU version of Vibranium is very similar, if not identical, to its comic counterpart. Given that the Wakandan government is extremely hesitant to export Vibranium, it's not difficult to assume that Captain America's shield represents all of the metal the US government has managed to acquire at the time.

    So we've basically got an African Atlantis sitting on a mountain's worth of insanely valuable metal (which we've known about for 70 years), and they isolate themselves to the point that nobody has yet been able to publicly get substantial amounts by trade or invasion? Not saying that's not what the mythos says, but that's awfully hard to believe.

    @TimS. I agree, but that's exactly what the mythos says. They refuse to export in any useful quantity, and nobody - not even Doctor Doom - wants to invade and risk ticking off the Wakandans.

    @DrydenLong: I disagree. Thor and Hulk only require us to accept - or suspend our disbelief in - the existence of a single incredible person. This Wakanda scenario requires us to revise our entire belief system about geopolitics, economics and human behavior.

    @Junuxx I don't think it's abnormal behavior that keeps Wakanda secure/isolated, but it's superior technology (computer-wise) and excellent defenses. People have tried to invade Wakanda before, but have always failed. There are a great number of mutants there, as well as the Panther Cult that have defended the city plenty of times. Geopolitics, economics and human behavior are all functioning as usual around Wakanda, but the city has managed to fight off all attempts at invasion. Commented May 7, 2015 at 17:54

    You basically have a self-sufficient, isolationist state, which is believable... especially when they have a monopoly on a priceless commodity.

In Captain America its mentioned how incredibly rare vibranium is. Stark appears to be saying, not that this is all the vibranium possible in the world, more that this is all the vibranium we have found to date. Now 70 years later, its not unreasonable for more advanced mining as well as just more time to actually look and find vibranium for their to be a decent sized cache. Especially something as rare and powerful as vibranium, there would be quite alot of money in it to find more of it. As its stated in avengers its worth billions.

    I'm really not sure why everyone is reading "That's all that's on earth," into Stark's comment. He says "that's all we have," or something to that effect that implies it's all that the US has on hand at the moment, but doesn't make any claims that's all exists.

    @Thorn "That's all we have" implies the US, and that implies the whole of humanity. That's really the only possibility, unless the Marvel Universe includes some sort of bizarre alternate reality where there are other countries...but as an American I really don't think so, that'd be awful weird.
