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.

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.)

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.

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.
