Good post nmth. We'll have to get together again some time to compare notes. I do have contacts in Utah and I am curious about their state, but I had no plans for the Moon Lake gathering. There's plenty of good stories about many different topics in Utah.
The Santa Rita copper recoveries I've referred to were not from the later porphyry deposits, but from the extremely rich and plentiful surface and shallow natives and oxides of the early life of the mine. That early history is excellently presented in the definitive
Santa Rita del Cobre by Huggard and Humble. The pack train copper deliveries to Janos began in the early 1800s. The Santa Rita-to-Caballos link was the well established pack trail from the Rio Grande at Caballos to the Mimbres River near Santa Rita. It was the route Lt. Emory mapped in 1846.
My interest is in the earliest activities at Santa Rita and environs. We know two church bells dated 1727 were found on the West Fork of the Gila River that are alleged (not proven) to have been cast at Santa Rita (
Church Bells). This discovery provides circumstantial evidence that the copper mine was exploited much earlier than the official 1803 date. Too, the records of Cabezo de Vaca's exploits in the 1530s indicate he was likely in southwest New Mexico and aware of copper artifacts in possession of the indigenous people there. Of particular note is that his traveling companion was Estevanico, who guided Marcos de Niza into the area in 1539 searching for rumored riches.
The "sort of thing I'm into" is searching for the truth of these matters. You're right - there is no definitive evidence for any of this, but there is an array of dispersed historical and anecdotal evidence that fits a pattern when pieced together over centuries. Relying on the "Noss Legend" or claims by the US government to define a narrative provides more sticky questions than easy answers in my opinion. For the time being, I'll stick with my comments in Post 2 above - always subject to change if warranted, of course.
Here's a Santa Rita miner with leather ore bags and a chicken ladder retrieved from a very old covered up mine tunnel that was exposed during early 20th century open pit operations.
