Underground workings at Brejui Mine.
Typical tungsten skarn ore with garnet, calcite, scheelite and diopside.
During the operation a shear zone hosted high grade copper mineralisation was encountered but was never mined.
Close-up view of secondary copper minerals that formed in the shaft. Due to its long operation time, the tailings of Mina Brejui are the most important of the area.
Sample of high grade tungsten ore with ca. 3 % WO3, main minerals are garnet, diopside and scheelite.
Same sample as before under short wave ultraviolet light high-lighting the scheelite.
