Kánya Hill rockslide
Silicified blocks of rhyolite and fine-grained conglomerate cover the ground of an old
beechwood. Some of the blocks have a roughly rounded shape and a circular hole in the middle,
as these blocks served as raw material for the millstones of the ore processing (Fig. 8). The
formation of the rockslide may be attributed to an earthquake causing the historical catastrophe
in 1443 at the Kánya Hill mines.
Lipót Shaft
The cavity of large diameter serves to demonstrate the explanation on the board about the
ventilation of the mines, the means of vertical transport and the vertical zonality of the
mineralization.
Teréz Adit and Csengő Mine
Two adits of different age can be observed here with their waste dumps. The Teréz Adit is still
accessible, reaching the Lobkowitz Vein on a lower level (410 m) than in the Mária Adit. The
waste comprises mainly the country rock of the veins, andesite with propilitic and potassium
metasomatic alteration, serving as the demonstrative background to the explanation on the board
about the rock alteration and attached mineral parageneses.
Jó Hill pit field
At this site several small pits show the ancient outcrop of a gold-bearing quartz vein; several
quartz (vein rock) blocks can be found in the debris. The site demonstrates the extent and
methods of the medieval mining activity and the formation and host rock of the epithermal gold
mineralization.
