Then why was he carrying around a flask of quicksilver if he did not "value" it?
One does not carry around a poisonous and expensive flask of quicksilver just for the fun of it.
According to the NPS, the slag pits at Tumacacori were big; are you trying to say that all of them were the byproduct of processing iron ore? I have a difficult time believing that.
Also it doesn't make sense, considering the sophistication of the Jesuit trade system, for them to engage in mass extraction of and refining of iron when they could simply trade for tools they needed, or for iron they could simply forge into what they needed.
I don't think I am the one who is biased here. Seems to me that you are the one ignoring the questions put forth to you, not me (e.g., the bronze bell sprue, or the fact that there were no known lead mines in Az before the arrival of Americans).
Mike also did not say "slag pits" in general, he said slag pits indicative of silver/gold refining. I am not knowledgeable about things mining, but I am pretty sure it is fairly easy to identify slag that is the byproduct of processing silver/gold ore as opposed to iron ore?
Also I understand Fr. Och's statement in the context that he knew how to use quicksilver to amalgamate, so it's pretty obvious what he was looking for, or what he valued.
There is no "other side" for me. Evidence that the Jesuits engaged in mining and refining in the New World is pretty overwhelming, from admissions made by the Jesuit fathers themselves, to historical documents, research, and analysis, to archaeological excavations. Results and conclusions from all three disciplines point to it as a fact, pure and simple.

Mike,
One question before I answer your questions. Where can I find the information that the slag found at Tumacacori was "Silver slag"?
Thanks,
Joe
<from NPS Archeology Program: Research in the Parks >[h=3]Preservation Mishaps: Area 37a[/h] In Area 37a., archeologist Paul Beaubien uncovered evidence for on-site production of the church bells in the form of two heating features he called the furnace and retort. A plaster mould resembling a bell was discovered near the heating features. Beaubien also found pieces of copper everywhere. In 1934, the floor of the circular furnace retort was “covered with a thin layer of copper which had solidified in place.”[SUP]28[/SUP] Fifty pounds of copper were collected, tested at the University of Arizona, and found to contain no silver.
Plaster mould found by Beaubien in 1934. The mould was found twelve feet east of the retort. Beaubien and George Boundey believed it could be a bell mould, suggesting that the bells were made at Tumacacori.
According to Beaubien, the features in Area 37a are the remains of a metal foundry; however, he was unsure that the plaster mould was for a bell. The idea that the mould was for a bell came from George Boundey who told Beaubien that he had found a plaster “core mould” of a bell that looked similar to the piece Beaubien found. Unfortunately, “while he [Boundey] was conducting some visitors through the mission, another party arrived and dropped a heavy rock on the object”.[SUP]29[/SUP]
During re-excavation of the retort in 1970 a piece of burned adobe with impressions of ridges similar to those found on bells was found. Directly outside the retort was “a fragment of cast copper which looks like a bell fragment.”[SUP]30[/SUP] In 1971 a cache of copper and slag shelved in the storage room at Tumacácori labeled “Caywood’s bell moulds” was found. There were some copper fragments similar to those exhibited in the museum as bell fragments that were “found in a cave near Tumacácori.” Presumably, Caywood’s “bell moulds” came from Area 37a, near the heating feature Beaubien called the foundry.[SUP]31[/SUP]
<GENERAL INFORMATION REGARDING THE NATIONAL MONUMENTS SET ASIDE UNDER THE ACT OF CONGRESS APPROVED JUNE 8, 1906, https://ia600508.us.archive.org/7/items/regardingnational00congrich/regardingnational00congrich.pdf >On the east of the altar room there is a sanctuary chamber, 16 by 20 feet, 20 feet high, covered with a circular roof built of burned brick, supported in the center by an arch. This is the only part of the mission which is now roofed over. In the south end of the church there was an arched partition which formed a vestibule. This partition has been removed. The outside wall of the north end of the church building is decorated with white plaster studded at regular intervals with clusters made of fragments of broken slag and broken brick.
He says the slag contained about 8 per cent lead, 3 per cent copper, about 8 ounces in silver, and about 1/6 ounce of gold, per ton"
... Almost forgot to add this but slag is also built right into the mission church at Tumacacori too! ...
... So the slag was not used in building the churches only at San Xavier del Bac...

However, before we can declare that the Jesuits were running a 'major precious metals operation', we'd need more information. Was the above referenced assay from a cherry-picked grab sample from a church structure? Were the alleged slag heaps at these mission sites documented and sampled? Do we have reliable data as to their sizes? What happened to them? If we could get a handle on the volume and content of the remnant slag heaps after 1767, we might be able to estimate the amount of ore concentrates that were smelted to produce them - and a more definitive picture of the extent of mining needed to provide the ore concentrates.
If this assay is true and representative of a large volume of slag heaps, I would say it's clearly a smoking gun for significant mining/smelting activities. At first glance, it certainly indicates at least some smelting of metals ore was done.
Unless someone knows one of the persons whom removed and sold the slag, and that person saved the assay reports and they are willing to share them, we are not going to see more information about the slag. More on this in a moment.However, before we can declare that the Jesuits were running a 'major precious metals operation', we'd need more information.

The copper content in the slag sample was high, suggesting the possibility that this particular smelter was primarily used for copper recovery. Is it possible that the primary purpose of the smelters was to recover copper used to produce bells and other copper or bronze alloyed castings? And, by extension, could the additional recovery of silver been strictly to manufacture church adornments?
<From the Wiki article linked above, citing Craddock, P., 1989, The Scientific Investigation of Early Mining and Smelting, In Henderson, J.(ed), Scientific Analysis in Archaeology, Oxford : Oxford University Committee for Archaeology, Institute of Archaeology ; Los Angeles, Calif. : UCLA Institute of Archaeology ; Oxford : distributed by Oxbow Books, 178-212>For slag rich in lead and sometimes tin with over 100ppm of silver, it might be considered as the waste of silver production (Craddock 1989).
Treasure hunters are convinced with the smallest amount of "evidence" and "documentation". Anything that gives even the slightest hint to further their beliefs is always blown out of all proportion.
Mike,
I was looking at that site this morning.
Anza may have been mistaken in his comment. What do you think, since you have used his statement to bolster your argument?
Also....Can you show me where Father Ortega states the early Jesuits were mining, instead of just establishing missions?
Mr. Bird seems to show some bias against the Jesuits, in general in the body of the the bulletin. It could be that bias colors his comments.
Take care,
Joe
deducer,
I don't find the above snippet that convincing of Jesuit mining. It does not give the date of the report, nor provide proof the it was the Jesuit's did the work at the smelter.
