Those I-clamps at Tiwanaku are made of a particular alloy of iron, copper and arsenic that requires a smelter operating at very high temperatures.
A scanning electron microscope determined that the clamps were poured into place, necessitating a portable smelter.
All this in an area current theory denies an iron age.
A spectrografische analysis of one of the view been left clamp has demonstrated that they consist of a very unusual alloy of 2.05 percent arseen, 95.15 percent copper, 0.26 percent iron, 0.84 percent silicium and 1.70 percent nickel. There is nowhere in bolivia a source for nickel to find.
Moreover requires the rarely occurring alloy of arseen-nickel-bronze a melt oven with which one reach can extreme high temperatures.

My own opinion is
They melted copper that already had 'contamination' in it. Melting copper isn't that difficult. Nor do you need a 'portable smelter' you just pour it into a pottery vessel that has wooden handles and walk it over to the spot which is itself sealed with a thin layer of clay (to keep it from leaking down the joint). I believe Perez(?) found the source of that metal in the 1970~but I'm going purely off memory, so don't quote me. A good question for the HoM.
Copper melts at around 1000c but various inpurities will increase or decrease this point. I believe in SA they were melting copper around 40000 BP while in the rest of the world, in particular Turkey and the Balkans they did so around 7000 BP.
If the copper were pure it would be interesting, the fact it isn't just demonstates the primitive nature of the operation.
Several civilizations came up with the smart idea of uses 'staples' to keep smaller blocks together.

Wow and where is the city located? Right in an area near both Chile and Peru – in one of the worlds greatest mining areas. However Hancock is correct – partially, there are no operating nickel mines presently in Bolivia, however in the past there were but – just in Peru and Chile which are nearby- not that the poor native ever traded – and of course there are deposit of copper in the nearby area which are not commercially viable in our world but fine for the natives use.
Yep the local native often followed modern boundary lines! LOL

Hey there Space
I live only to serve, or somethin' like that.
What is the purpose of life?
The purpose is so simple that most people don’t want it. The purpose is to prove to ourselves what we are, what we are made of. After doing so, that will determine where we go once we are off of this planet. Humans are here to determine where we go after the moment of death, which is related to how much more information and truths we become aware of, or not.

I'd say that Baldin has overcomplicated the question. The purpose of life is to perpetuate life. As motives go, it's elementary.
