The article deals with the geological structure and the history of exploitation of the iron ore deposit at the foot of the Koski (Kózki) Hill within the Brzechów Range, located 2 km north of Daleszyce in the Holy Cross Mountains. The ores belong to the Porzecze Claystone Member, which is situated on the boundary between the Lower (Emsian) and Middle Devonian (Eifelian), in the lower part of the Barania Góra Formation. This member extends in a narrow zone between the sandstones of the Winna For¬mation and the bioturbated dolomites of the Brzeziny Member in the north-ern wing of the Daleszyce Syncline, located in the Kielce Region of the Holy Cross Mountains. The deposit consists of irregular, nested clusters of mainly limonite and clay siderite, embedded in dark claystones. Iron ore mining began at the beginning of the 17th century for the needs of the forges in Belno, Smyków and Napęków. In the mid-18th century, the deposit was considered exhausted. After a hundred years, mining was briefly resumed and the ore was supplied to the blast furnace at the Wojciechów Ironworks near Szczecno. After that, the Kózki mine was abandoned.
