The Řeka quarry is the exclusive mineral deposit of Těšín sandstone. This three-storey quarry with a height of approx. 27 m is located on the northern edge of the village Řeka in the Moravian-Silesian region on the eastern slope of the hill Godula, west of the road passing through the village. According to available information, mining began in the quarry at the end of the 19th century. At present, mining is carried out using expandable material or blasting. In the upper parts of the quarry, the sandstone is more weathered and the individual layers have a thickness in the order of no more than tens of cm. Monumental blocks (layer thickness up to 2 m) can also be mined in the lower part of the quarry. The mined stone is processed in the quarry by line hammers for products of rough stone production, but it is also used for noble stone production for the production of tiles.

Petrov Quarry is located in the cadastre of the Žulová municipality in the Jeseník district in the Olomouc region. It is a well-accessible medium-sized quarry with a quarry wall on the southern to south-western edge of the quarry, almost 200 m long. Granite colored gray, yellow or yellow-gray is mined in the quarry. It is suitable for block mining, rough and noble production. Irregular pieces of stone are drilled according to the shape and predominant locks of separability and according to the requirement for the size of the blocks by vertical boreholes and subsequently split with tongue wedges. The raw material extracted in the quarry is also processed in it by breaking and splitting into products such as paving blocks, curbs, curbs, diggers, rigols and throwing material.
