From another thread:
A very fancy word, that in reality, is about absolutely meaningless. Similar to all of the other 'technology' they have used to keep the series interesting.
They are simply looking for a percent composition of the lead, and other trace minerals, and the isotope count on the lead, then comparing it with other samples.
You have to compare apples with apples. As an example, we use this, or a similar process to compare batches of Spanish coins, and the origin of minting. This tells nothing of the origins of the gold that was used to make the coins. Within each 'batch' of the minting process, the coins have similar chemical composition. Each batch is distinct, and each mint is very distinct. You cannot sample a coin and determine where the gold was mined.
Remember, much of the coinage was produced from artefacts which had been melted down.
So, they found no artefacts with similar composition, which is surprising, as lead has been used for centuries.
As shown above, to say that a manufactured artifact, "could' have origins to a certain mine is laughable.
What is far more conceivable is that bullets were melted down to make the artefact, as all bored soldiers know, we sit around and make stuff.
At best, they figured out it was made from lead, other than this, without a match to a manufactured artefact, the results are meaningless.

Hmm it's late and I'm tired maybe I didn't use the proper term but isn't that the work that Oxford did?
