This is embarrassing that I lost the card I had with the location information and can not remember. Arsenopyrite, and Löllingite are often found together, but rarely with Baryte - and such large blades of light blue Baryte, at that. This piece is 6 Kg and 18 x 14 x 12 cm! The Arsenopyrite xx are nicely formed, but not large. The Löllingite is interspersed throughout. The Baryte xx are obviously large and well formed. I spent hours with mindat and could find no photo containing the three. Huanggang Fe-Sn deposit, Hexigten Banner, Chifeng City, Inner Mongolia, China has no mention of Baryte. Could it be Panasqueira? Baryte is listed there, but I've not seen any large blades of it like here. Shortly after purchase, I packed it away. Yesterday, many many months later I was unpacking it and the label only had the minerals, which I knew just from sight. No location info with it to my embarrassment. If it is any hint, the tiny dark spots on the Baryte are Arsenopyrite xx grown into the Baryte. Any suggestions welcome.

Why Arsenopyrite? Why Löllingite?

The Baryte looks like it's from Bou Nahas, and then it could be associated with Pyrite and Marcasite...
