No puzzle to solve, but this one is a bit deeper inside than it's
predecessor just down the trail, so the above coords take you to
one of two tunnel entrances. You can get to the cache from either,
as both tunnels meet toward their ends 
. The cache is hidden at the end of a
short (6 feet maybe) annex off of one of the tunnels, under a
couple rocks. Without a flashlight you won't be able to see inside
the annex, which is why I placed it there - to help hide it from
accidental discovery. Please replace as found!
The integrity of these tunnels is good, as they were dug into
mostly rock (and have lasted over 150 years), but you should be
careful while inside not to loosen any stones from the walls or
ceiling! The cache is on ground level.
The miners would dig these tunnels looking for quartz deposits,
and I wonder if these two were from competing miners. The entrances
aren't quite at the same elevation, and I can't imagine why the
same miner would want two of his tunnels to intersect. Just one of
those things I like about finding places like this, what the heck
was going on?
Terrain is a little higher than Not (a) Mine! because more
crawling is required for this one.
- after a week again just like
the other mine!
