Still no silver, but it does mention aluminum several times. At that time, silver would probably been easier, maybe even cheaper, than aluminum. Did you know that one year there was such a shortage of copper that silver was substituted in wires?
A very early endeavour was the electromagnetic isotope separation (EMIS) process using calutrons. This was developed in the early 1940s in the Manhattan Project to make the highly enriched uranium used in the Hiroshima bomb, but was abandoned soon afterwards
Caultrons are mention in many other places as well. So why does official US documents not mention anything about magnets or caultrons? I am sure Anons know the answer already.
At that time very little was known about the metallurgy of uranium, so there was a lot of experimenting at various sites. Here's the chemical process of turning it from ore to a salt, which is a general first step in refining: https://www.osti.gov/opennet/manhattan-project-history/Processes/UraniumMining/uranium-refining.html
This is quite interesting, both because of the historical groping and because of all the uranium sources, including Canadian. Having somewhat purified the uranium and found ways to dissolve it, the next step was to make actual metal out of it. https://www.osti.gov/opennet/manhattan-project-history/Processes/PlutoniumProduction/plutonium-fabrication.html
More experimenting. So far, silver is not mentioned at all, so if you aren't into historic chemistry I will say it's pretty dense, although the section on procurement might be related to Uranium 1. https://www.osti.gov/opennet/manhattan-project-history/Processes/UraniumMining/uranium-mining.html

iirc, silver was used to build huge magnets that were necessary for some step of this process, not directly used in mining.
