The deposit's industrial resources amount to over 328 million tonnes of copper ore. The copper content in the ore is 1.28% on average, and the silver content is 54.5 g/Mg. The dominant lithological type of copper ore is sandstone, which accounts for nearly 70% of the resources. The depth of copper ore in the Lubin deposit ranges from 368 to 1006 m.
