It´s funny that the baryte is not listed to Rozalia mine list of minerals,even though fact that first massive occurrance of baryte crystals is known from late sixties - 1968, from VI level South from Rosalia vein. This baryte occurrence was noted in hanging wall road drifted through contact metamorphose changed creamy colured marble. After few metres was found big amount of cavities filled with thousands od snow white lustrous crystals of baryte, formed mostly as "roses" and "cock ridges" But is possible that this baryte found and mineral occurance was throw into shade by nearby occurance of Hodrusite - type mineral from this locality.Apropos , the baryte "cave" in VI level is possible to visit also on this time...

Nex bigger occurance of baryte was found in Rosalia vein North in XII level in Rosalia structures in ceiling of road as thin leafs up to 6 square cm in 1993 and by "Gym" in XIV level North. After that from end of 20th century was every year found some occurrances of baryte crystals. Previous year was found relatively big outcrop of white big leafs of baryte crystals covered by secondary pyrite, calcite and other minerals up to 7 cm legth of crystal edges. I think that in problematic of baryte from Rosalia vein is interested geologist Dr. Stanislav Jelen from Slovak Academy of Sciences.

It's listed now :-)

Basically, if a mineral known to occur at a locality is not listed on Mindat, it's just because no one added it yet. The species lists are not complete, and never will be. Karsten, you are welcome to help add more! (Just read the Manual about the procedure for doing this.)

OK Alfredo, thank you. I´m brand new there, and active in more other pages. Griefly I don´t have enough time for study of structure of all pages. Maybe later... ;-) Can you please correct also the information, that Rozalia mine was commenced in text under the name of locality? This is not correct, mine is under function and production continuously from 1950 to this time. This year was rised up brand new miner clothes room and offices building nearbyLower Rozalia adit (this one in title photo) fully modernised the compressor building etc.Previous year Gold production was about 30 kilograms...

Quartz

Pyrite

Chalcopyrite

Calcite/Dolomite/Siderite (generally carbonates)

Galena

Sphalerite

Hematite

Hodrushite

Chlorite

Scheelite (microscopic)

Rezbanyite(microscopic)

Tetraedrite (microscopic)

Hi everybody,

I have one delicate question about references to ore deposit listed minerals.

I have visit of Central Slovak Mining museum , Mineralogic exposition for shots of some photos of mineral specimens mostly from Slovakia.

There I found some rare specimens, there are not listed on Czecho-slovak mineralogic literature which I have at disposition.

For example native copper from Rozalia vein, Hodrusa-Hamre, or Chalcantite from Nova Bana deposit, or founds of some minerals from localities, there are complete not listed in literature ( Blue baryte from Sasovske Podhradie) and so on.

My question is about your opinion: Is the information quoted in mineral label in official mineralogic museum (few kilometres from locality) enough reference ?

Custodian of mineralogic collection in museum was every time mining engineers and graduated geologists.

As second photo I can publish by this kind of samples the same specimen photo with original label as displayed on vitrine.

Thank you for your verdict in advance.

Karsten, Central Slovak Mining Museum specimens would be excellent references to add to localities, and very welcome on Mindat!

Of course, all museums contain erroneous information, just like private collections do, so any species entered on a list might be questioned later, just as any other data on Mindat can be questioned and/or improved, but listing everything from the museum that is not yet on our lists would be a good start. Experts on individual localities can then chime in if there is anything they'd like to dispute.

Is this mine still working and if so who can I contact about a possible visit (I am a mining geologist and mine explorer)
