The Mountain Consolidated, or Mt. Con, was the deepest mine at Butte. The main shaft was 5,380 feet deep, and because of its depth, it was a very hot mine to work in. It produced excellent specimens of bornite chalcocite, enargite, and pyrite. (Author: crosstimber)

The next morning I walked back to base where I’d left my car at the Cairngorm Ski Centre. The fog came back with a vengeance and the wind blew strong, but I spied out the route before the view was obscured and used a map and compass. After about an hour I came across a large familiar footpath which led me safely off the mountain. I decided to return when there was less snow, which I did six weeks later for one superb day in July.

This piece has a 6 cm multiple stepped purple rimmed fluorite sitting on 2 perfect Quartz crystals. In the valley between are some small dark brown Scheelites. There is also a small chalcopyrite on the back side. This measures 11.3 x 9 x 5 cm and is from Yaogangxian Mine, Hunan Province, China (Author: VRigatti)

This piece is complete all around with interesting etch features. The etching also forms these rectangular channels that go into and sometimes right through the xtal. Note in pictures two lengths of fishing line pushed through two of the channels. One line goes through a straight channel and the other goes though one of the channels that has a 120+/- degree bend.

This piece is rather difficult for me to capture given the simple photographic equipment I have. I like the exremely fine fibrous habit of this Xonotlite. The specimen is 5/8" (1.6cm) accross (Author: Jim Prentiss)

This POW Epidote was given to me a few yars ago by an old family friend. The crystals are quite small averaging 5/16" (8mm) long, embedded in Quartz crystal. The Epidote crystals are doubly terminated, but very dificult to get the detail here. That is one of the endearing aspects of this little guy. The field of veiw vertically is about 1 1/2" (3.8cm) (Author: Jim Prentiss)

This pseudocubic crystal cluster of Apophyllite-K(OH), (Bah Humbug! I prefer Hydroyapophyllite) is 1 3/8" x 3/4" (3.49cm x 1.90cm) . it is from N’Chwaning Mine II, N’Chwaning Mines, Kalahari Manganese Fields, Northern Cape Province, South Africa (Author: Jim Prentiss)

This shows you what a Home-made Printed Circuit board looks like before it is drilled and stuffed with electronic components. These boards are so easy to do it is scary! You start off with a circuit design printed on a clear plastic sheet, place the sheet over a copper board covered with photo resist (Riston) and exposure it to a source of UVA (or sun light), develop and then removed unwanted copper with etchant (ammonium persulphate). The end result is shown in the photo. And the holes are drilled to accept the parts. (Author: Lumaes)

this slender prismatic doubly terminated little crystal is Childrenite on Microcline from Lavra do Poco Dantas, Minas Gerais, Brazil. It is 1" x 1/8" (25.4mm x 3.2mm). I have read that Childrenite makes a good "new species" mineral as it is only known in crystals (Author: Jim Prentiss)

This specimen is a pretty good looking mineral for one of my type locality pieces. The habit and color are typical of the Aghbar Mine, Aghbar, Bou Azzer District, Tazenakht, Qiarzazate Province, Suoss-Massa-Draa Region, Morocco. It is named after Wendell E. Wilson, Editor and Publisher of the Mineralogical Record. The specimen measures 1 1/4" x 1" (3.18cm x 2.54cm). (Author: Jim Prentiss)

A large pipe cavity lined with apophyllite and stalactitic thomsonite. The pipe is about 20cm in diameter. An unusual occurence; haven’t seen another one like it at Moonen Bay or elsewhere.
