In the valley of the Hrazený potok (creek) south of Zlatý Kopec, tin ore was extracted from steep quartz veins truncating the surrounding phyllites as attested by countless mining remains such as adits, pits, heaps, shaft depressions or open cuts. Due to a favourable morphology, the deposit was developed by dozens of adits and rather shallow shafts. The largest concentration of old mines from the 16th to 19th centuries is situated on a steep hillside above the right bank of the right tributary of the Hrazený potok (creek) and above the left bank of the Hrazený potok. A large heap of the Hoffnung zu Gott mine just above the settlement dates back from the last period of mining in the 1920s and 1930s. The entire area is located in the forest and has preserved the authentic appearance of a mining landscape. Typical for the whole area are also dozens of circular sites of former charcoal kilns.
