Here are some more pictures and minerals from the Alice Mine!

Stope Pillar
Here is another view of the Alice Mine stope. Miners try to leave pillars when they mine as a rockmass and hanging wall stabilization technique. Here is a view of a pillar.

Mining SublevelRecent Activities -Alice Mine Visit, California, Page 2

Mining Sublevel
This is a sub level between the two adit levels at the Alice Mine. It would have been used for exploration, equipment and supplies storage, etc.

Upper Level Staging
This is a picture of the upper level staging from below in the stope. We climbed up there to exit the stope.

Mineral Specimens
In the upper adit drift, where it intersected the vein, I found some interesting quartz crystals on blue chrysocolla. In my miners cap lamp, it sure looked sparkly! Not great specimens but I thought it would be a good idea to take them home, clean them up and see what they really are.

Upper Adit Exit
Here you can see Paul headed out the portal of the upper adit to daylight.

Lunch time!
It is a pretty nice view across the desert up there at the upper adit portal. Great place for lunch!

Chrysocolla, QuartzRecent Activities -Alice Mine Visit, California, Page 2

Chrysocolla, Quartz
This sis a specimen, typical of the quartz-coated chrysocolla that I recovered from that little seam in the upper adit. The chrysocolla is actually composed of largely, tiny needle-like crystals that are probably pseudomorphs of chrysocolla after malachite or some other secondary copper mineral.

Chrysocolla, Quartz
Here is another rich chrysocolla and quartz specimen.

Gypsum, Chrysocolla, QuartzRecent Activities -Alice Mine Visit, California, Page 2

Gypsum, Chrysocolla, Quartz
This one was a little different. It had elongated, white gypsum crystals associated with the chrysocolla and quartz crystals. Field of view is about 4.0cm.

Chrysocolla ps Malachite?
These are the needle-like pseudomorphs I was mentioning earlier. Sharp!

A little closer view. The field of view is only a couple of mm.

Quartz, Chrysocolla ps. Malachite
This image shows a gemmy quartz crystal on a blue crystal. This must say something about the paragenesis?
