Lead is not soluble in water and so would not be deposited in the speleotherm\mammilaries
​
Native lead isn't soluble, but what about lead carbonate, which is? Couldn't you get some of that in such an environment? (I don't know, my chemistry is not that good.)

Whereas what I found was word for word the same apart from the words "(except Lead carbonate)":
​
All carbonates (except Lead carbonate), sulfites and phosphates are
insoluble EXCEPT those of ammonium and Alkali metal (Group IA) cations.
​
On the other hand, the website I found this on doesn't look particularly trustworthy.
