The surrounding terrain is etched with a number of funnel-shaped pits, which are the remains of an old mining cinnabar. Mercury mine on land Teplá monastery was mentioned in 1549, the greatest intensity of mining came in the 17th and 18 century. Mined to shallow shafts, which were hollowed into weathered shale cinebarit mineralization. Robbed rock sailed on the spot – the remains of small reservoirs and water ditches are still visible today. The total amount of cinnabar mined in Bezdružic Starin is in the range 300×300 m and content found 25–30 g / t only estimated at tens of kilograms to several tons. The 70 the last century took place in the vicinity Bezdružic Geological Survey. It was found that with vermilion nehojným pyrite impregnation form, fill cracks and nests grained quartz phyllite penetration milky white color. Vermeil or cinnabarit located here rarely piece, but far more granular mineral, often as a grainy meat or coatings. Cinnabar is one of the few sulfides, in which we can observe today as there is, in the thermal springs at a temperature of about 80 ° C in the dying areas of volcanic activity (eg, Kamchatka). Cinnabar is the most important ore from which mercury is extracted, of which the largest producers in the world today are Russia and Spain. Mercury is the only liquid mineral and occurs in the form of pewter white tiny balls just to cinnabar. It is mainly used in measurement and amalgamation of gold and silver (especially in their production). It is very poisonous. The occurrence of cinnabar in Bezdružic is economically insignificant, but it has great importance in terms of metalogeneze. Yet unresolved is the question of the relationship of gold and mercury mineralization. Pure gold and cinnabar, although present in the alluvium along streams, the primary rock next to each other but not yet found.
