I thought this "matchbox ore " argument was settled a couple months ago in the "New Show on the Dutchman" thread (early March), when gollum attempted to push the same idea. He eventually relented when I supplied Thomas Glover's own opinion on the "database" concept.
Here is the salient post, #1047, by me:
This is getting painful to watch - what are you trying to prove with your totally fallacious database prop? I'll quote Glover himself on the issue, The Lost Dutchman of Jacob Waltz, Part 1: The Golden Dream, page 275. "... the entire premise that the ore could be tested against ore from every known mine in Arizona is ludicrous. No one, nor any institution, has such a collection of gold ores. It does not exist."
Glover tested the jewelry ore against the Vulture Mine and six other ore samples known or suspected to have come from the Superstition Mountains and Goldfield mines. More: "No ore samples survive from many of the documented historic mines, some of whose locations we may not even know today. Anyone who has studied mining history knows that it is often poorly or incompletely documented. Consider the number of early mines worked for only a brief period, exhausted of ore and then closed over a century ago; the number of mines worked without declaration; the early mines worked which were incompletely documented; and the number of mines for which the documentation has been lost or destroyed. Given this history, it is silly to think that a collection exists anywhere with 'samples of gold ore from every known Arizona mine' ". Page 282.
I believe I pointed out the same information in Post#927. If you can't accept my observations, why not Glovers? In effect, the jewelry ore could have come from anywhere in Arizona. Or CA, NM, or MX too, for that matter.
Earlier Post # 927, by me:
Glover made a decent case that the ore did not match the selected ore samples saved from a part of the Vulture Mine, as I recall, and maybe some other grab samples saved from some of the the Gila/Salt area mines. Fine and dandy. PERIOD.
The rest of your statement implies that the "LDM sample" was matched against samples from "all known mines", which is absurd. In the first place, where exactly is this database and/or ore sample collection that includes all these known mines? Mines from CA, AZ, NM, MX, CO, et al? Hundreds of mines, many of them with different geology in different parts of the same mine. Possibly thousands of potential matches. Who exactly was it that collected these samples and stored them, and where are they available for analysis? Glover didn't provide these details.
Secondly, and more to the point, why would anyone believe that all the point sources of rich ore with visible gold showing (picture rock) from the early Anglo period are known? There were thousands of small mines, glory holes, shallow prospects, etc that yielded picture rock in various quantities. Hell, there's an old Spanish/Mexican glory hole ten minutes from my house that has never even been claimed that yielded several pounds of thick wire-gold as recently as 40 years ago. The hole was never more than six feet deep. The matchbox ore is terrific stuff, sure, but by no means unique. Not even close.
