Namibia

Spring 23
Mimetite crystals ranging from colorless to gem yellow are scattered on all sides of this gossan matrix. There are zones of Arsentsumebite adding some greenish color as well. Some very tiny unknown colorless crystals are also noted as is a blue-green hue on some Arsentsumebite that seems to be another sort of alteration mineral. Most crystals are complete, undamaged though close exam does find some damage but not very noticeable. Nicer in person.
Mimetite var. Campylite
stock #19.1-790
Dry Gill Mine, Caldbeck Fells
Cumberland, Cumbria,
England
6.6 x 2.7 x 2.1 CM (cabinet)
price: $950
Spring 23
Esthetic, classic and unusual British "Campylite" from the vintage locality of Dry Gill. Well-crystalized Mimetites are clustered on a dark gossan cast that is hollow on one side. Especially intriguing is the outside facing half of the crystals are a dark olive green but the inner half are reddish orange. In excellent condition, this is the type of Mimetite that made this small mine world famous. Ex Hitchings collection, obtained by trade in England in the 1970 era but almost certainly a far older specimen from the golden years at the mine. This site began formal working in 1846 and operations ceased in 1869. While the mine produced best in those years there have been some good pieces collected about a half century ago as well.

Mina Ojuela, Mapimi
Durango,
Mexico
5.3 x 3.7 x 2.1 CM (cabinet)
price: $480
Spring 23
A fine "wet-look" Mimetite in elongated balls and fingers covers a contrasting matrix. Excellent color and luster in fine condition. The surfaces have a distinct sparkle as well. From the find about 7 years ago at Mina Ojuela, these look very much like the prized San Pedro Corralitos Mimetite from the 1980 era. As these are a more recent discovery the price for a fine piece like this are considerable less than the older material yet the look is very similar.
Colorful and classic Tsumeb specimen with flower-like sprays of light yellow Mimetite on a field of green Malachite balls. The specimen is quite richly covered and the Mimetite is well-distributed. One of the many reasons that Tsumeb is such a revered locality is the amazing diverse combinations of mineral species, elements, alterations and forms that are sometimes very esthetic. This is a choice example of these lead and copper species together. In very good condition as seen. The surface has hundreds of Malachite balls which with close exam are seen to be in the shape of Cuprite crystals (dodecahedral form) covered and altered to Malachite with a botryoidal surface. This alteration is very much like the classic Chessy, France pseudomorphs but with a different texture. An excellent display quality specimen with lots to see on it.
Mimetite - old find, unusual color

Pingtouling Mine, Liannan, Sanjiang
Guangdong Province,
Chile
4.8 x 2.8x 1.7 CM (miniature)
price: $390
Fall 22
From the early finds at Pingtouling which were famous for bright yellow Mimetites, this is a deeper orange hue. The mine was flooded and collapsed more than 20 years ago, but the size and quality of these lustrous crystals helped them to become modern classics. This thumb-like matrix is covered by fine crystals on all sides, and the condition is excellent. The crystals all have a wet-look luster. These have become scarce and this color is even more uncommon.
Mimetite with minor Wulfenite
stock #22.1-127
Mina Ojuela, Mapimi
Durango,
Mexico
4.9 x 3.2 x 2.6 CM (miniature)
price: $500
Fall 22
Large (for the specie) and well-isolated balls of Mimetite in an attractive cluster. From the great Mina Ojuela, the larger balls exceed 1 CM in diameter and have excellent color and satiny luster. Some tiny pointed habit orange Wulfenites are present as well, but this is really a Mimetite in fine classic form. In excellent condition (no visible damage or bruising) this is a choice piece from the 1980 vintage finds that is not like any of the more recent Mimetites from here.

San Pedro Corralitos, Municipio de Casas Grandes
Chihuahua,
Mexico
2.8 x 2.3 x 2.7 CM (thumbnail)
price: $690
Late Summer 2021
From San Pedro Coralitos, an older specimen with excellent form. Well-defined bright yellow balls of Mimetite are in both clusters and isolated on contrasting matrix. I have not seen many good thumbnails from this famed locality where most specimens were larger but this one is especially esthetic. In perfect condition on the display side, there is only a small contact on the backside of one ball not visible on display. There is no damage anywhere, this is a competition quality thumbnail.

Level 13, Potosi Mine, Santa Eulalia
Chihuahua,
Mexico
6.3 x 4 x 2.3 CM (small cabinet/ large miniature)
price: $440
Early summer 2021
Botryoidal green Mimetite in well-formed balls covering one face of matrix. From a quite old find at the Potosi Mine of Santa Eulalia, this is remarkably like the famed Mimetite of San Pedro Corralitos, but it is green instead of yellow. The Mimetite has two distinct tones of green and has a satin luster. This is in very fine condition, quite esthetic and with no evident damage on the display surface.
