Many thanks for your kind words. I do appreciate the vote of confidence. It was not an easy mineral to photograph, and I took many photos until i was happy.

 Description:
Musonoi Open Pit

The Musonoi mine has been a locality for many world-class uranium, copper, and cobalt bearing minerals (Oosterbosch et al. 1964, Gauthier et al. 1989). The mine is located in the Democratic Republic of Congo on the outskirts of the mining town of Kolwezi in an area known as the Katanga Copperbelt. The ore-bodies of the Musonoi mine, and the nearby Kamoto mine, have been mined since the beginning of the 20th century for copper and cobalt. Initially, the Musonoi mine was mined for Chalcocite and Digenite.

The specimen comprises a vuggy Quartz matrix hosting many well-formed crystals of Meta-Torbernite.

Usually Meta-torbernite is a dehydration pseudomorph of Torbernite. However the specimens from El Sherana were formed by direct deposition from a supersaturated solution, which produced true crystalline Meta-torbernite, with a dark green colour, translucent diaphaneity and a vitreous lustre.

A note from Les Presmyk on the Copper Queen location.
As a general statement there are very few verifiable azurites and malachite’s from the Copper Queen mine and the few that I know of are fairly average. The Copper Queen mine only operated from 1884 to 1888, when the Czar and Holbrook mines were developed and opened. In addition, these became the primary specimen producers for the next 10 or 15 years. And, if you have any of my labels saying they are from the Copper Queen, they are wrong. This is the result of the research I did for our book. And I don't remember how many dozens of labels I had to change as well.

Dear Les:

Many thanks for your kind words. It would appear that the vendor who sold me the specimen made a mistake, though no labels were provided. I suppose I should re-name the locality as the Czar mine.

Based on the comments of some of the qualified mining historians I have spoken with, the Czar mine is still considered a classic historical locality too.

Many thanks for you cordial comments.

Silvia

Actually that was from an e-mail from Les to me correcting some of my labels that were either wrong or I did not have that information available to me. When it comes to Bisbee if you do not have a good location for it just label them Bisbee. A good reference book is called Collecting Arizona, State of Mines, Legacy of Minerals. edited by Terry C. Wallace. I believe this book is still available

Many thanks for your help.

My partner reviewed the labels again and pointed out to me that the seller gave the locality as the Copper Queen mine, Bisbee.

Does this mean the seller is in error? Who knows, but it does happen!

Reviewing the morphology of Azurite crystals from the general area, I understand that all the major mines in Bisbee were very close to one another; it would appear that the specimen uploaded may have come from the Czar Mine.

Again many thanks for your input.

All the best

Silvia

A beautiful electric blue cluster of ‘razor’ sharp Azurite blades on a small amount of matrix from the famous Milpillas mine. The largest blade measures 20 mm in length.

Hi Silvia,

as usual, I enjoyed your latest contributions. The specimens and photos are really really nice, the background infos are wonderful and reading your posts shows how much you love mining and minerals, wonderful to see people so passionate and obsessed with details :-)

I like the Elmwood specimen, Elmwood Mine is one of my favourite localities even though it produced only a few common mineral species. I had a very nice Elmwood sphalerite in my collection ( https://www.mineral-forum.com/message-board/viewtopic.php?p=49403#49403 if you like to see it) and though they may stand in the shadow of the top-class fluorites and calcites from that locality, I always like to see a good sphalerite piece from that mine. And your's is a very good one!

Though I'm not that much into azurite, and not that hyped by Milpillas as many other collectors, I would really enjoy to see more. Always exciting to learn more about the surroundings from where our display specimens come, no matter if it's a favourite mineral or locality!

Nice to see other collectors enjoying this. I also have several specimens where I love to study the matrix again and again. I like it when you see how the crystallization went through the mother rock, how veins and vugs were filled with the material or how different minerals grew together or in succession.

Thanks for your contributions, I hope there are a lot more to come :-)

Regards
Tobi

Hello Tobi:

Your kind words are always welcome.

Copper is a key element in our mineral collection. Copper is one of a few transition metal chemical elements that produce a wide array of collector quality minerals.

Milpillas minerals were certainly the object of much marketing hype. At a few of the Tucson mineral shows we attended, we saw Milpillas material selling for greatly inflated prices. We saw some Milpillas specimens composed of druses of Cuprite on matrix selling for $1000’s of USD. We waited a few years, as we knew the Milpillas ore-body would continue to yield good material for at least a decade. It pays to read the scientific literature and the reports issued by the mining companies. We now have a full suite of material from Milpillas obtained at very competitive prices directly from the suppliers.

I looked at your very fine Sphalerite from Elmwood. Sphalerite is also one of our favourite minerals too. We often recommend Sphalerite to new collectors as it is possible to obtain some outstanding specimens at very competitive prices.
